1862 COMMISSION TO STUDY THE DEFENSES REPORT

WASHINGTON, December 30, 1862. Hon. E. M. STANTON, Secretary of War:

SIR: I herewith present you the report of the Commission ordered by you to examine the Defenses of Washington, and report to you as to their efficiency, &c. It will be seen that the Commission approve generally of the lines established and of the works, and that they attach very great importance to them; that they recommend some additions to or modifications of the existing works; some new works (five or six) to strengthen certain parts of the line, and that they purpose to add a new feature to the defensive system by the construction of works to defend the river from maritime attack. Their reasons are given in full, and it is not necessary for me to dwell upon them in this place. The amount expended upon the system up to the time when I relinquished the charge last spring to take the field with the Army of the Potomac was about $550,000. This applied to the construction of upward of fifty forts and a number of batteries. Some of these works were of large dimensions, and many had, besides the usual magazine, extensive bomb-proofs, for the protection of the garrisons. Notwithstanding the number of works built, the defensive system was in some parts still very weak, and everywhere there was need (as I stated in a report to the Chief Engineer U.S. Army a year ago) of auxiliary works, more efficient armament, &c.; and I also stated that there were important gaps in the line which should be filled. When the Army of the Potomac retired from the James River, I was ordered to assume the command of the works and troops of Washington, and there was apprehension felt (as the result proved, rightly) for the safety of Washington. Of course, it was my duty, both as engineer and commanding officer, to use the time and means disposable to increase the strength of the defenses. The northern side of the city, between the Potomac and Eastern Branch, which had been little exposed to attack the summer before, was, in August and September of this year, the most likely to be assailed, and from the Potomac to the Seventh street road it was exceedingly weak. When, for want of rank, I was superseded in the command, I continued to discharge the duties of engineer, under the full conviction that in that crisis (September 1) I could render no more valuable service to my country than to perfect the defenses of Washington. I commenced on my first arrival to strengthen this part of the line. I directed the enlargement of Fort Massachusetts, and laid out forts and batteries to make a complete connection between the first-named work and Fort Alexander on the Potomac; at the same time I felled the timber to a distance of a mile in front, thus exposing the ground and making it impracticable to the enemy's movements. Ci vii War Defenses of Washington PageC-7 Historic Resources Study Part I-Appendix C

On the south of the Potomac, rifle-pits were thrown up between the works, new gun-platforms laid, and the armament improved; obstructions made across the valleys of Four-Mile Run and Hunting Creek; Fort Lyon strengthened by advanced works, and batteries for field guns prepared. On the most prominent or commanding points 100-pounder rifled guns, on center-pivot carriages, were introduced, to bring under fire the whole external area an enemy must occupy in approaching our lines. These, and similar works, are fully described in the report of the Commission. With no other assistance from engineer officers than that of a single officer (valuable, indeed-that of Lieut. Col. B. S. Alexander), it has been necessary to employ a large number of civil assistants, superintendents, and overseers, to supervise the works and troops and laborers employed. This, together with the hire of laborers, the purchase of lumber and other materials, has required a large cash expenditure. You authorized (in August, I think) the application of $50,000 from the appropriation for the contingencies of fortifications, field works, &c.; to the Defenses of Washington, $50,000 more. This last sum will have been nearly exhausted at the end of this month. It is exceedingly difficult to estimate for this kind of expenditure, and as the exigencies of the service have, since my return here, made it impossible to furnish the number of troops required for the labor, I am obliged to suppose that much of the additional work proposed by the Commission will be done by hired labor, and, making reference to past results, to estimate that an additional sum of $200,000 will be needed; for which I ask that an appropriation of Congress be requested. I also request that, until such an appropriation be made, I may be authorized to apply an additional $50,000 from the existing appropriation for contingencies of fortifications. There has been but one other system of field works that I know of that is analogous to this in extent and character-the famous lines of Torres Vedras. These frustrated the design of Napoleon of driving the English from the Peninsula. They consisted of a greater number of works, but the works were smaller, and much less expensive in workmanship; yet on these lines, in a country where labor commanded but one tenth of what is paid in this country, $1,000,000 was expended from first to last. I am, very respectfully, your most obedient, J. G. BARNARD, Brig. Gen., and Chief Engineer Defenses of Washington.

[lnclosure.] WASHINGTON, December 24, 1862.

Hon. E. M. STANTON, Secretary of War: SIR: The Commission appointed by Special Orders of the War Department, No. 312, dated Washington, October 25, 1862, "to examine and report upon the plan of the present forts, and sufficiency of the present system of defenses for the city," report as follows: The system of works constituting what are called the Defenses of Washington may be divided into four groups: First, those south of the Potomac, commencing with Fort Lyon, below Alexandria, and terminating with Fort De Kalb, opposite Georgetown; second, those of the Chain Bridge; third, those north of the Potomac, between the Potomac and the Eastern Branch, commencing with Fort Alexander and terminating with Fort Lincoln; fourth, those south of Eastern Branch, commenting with Fort Mahan and terminating with Fort Greble, nearly opposite Alexandria. The perimeter thus occupied, not counting the interval from Fort Greble to Fort Lyon, is about 33 miles, or, including that, 37 miles. In the first group are twenty-three field forts (including the small , Forts Bennett and Haggerty, and the external works of Forts Lyon and Blenker). In the second group are two forts (Ethan Allen and Marcy) and three batteries for field guns. In the third are eighteen forts, four batteries, permanently armed with heavy guns, besides about fourteen batteries for field guns, some of which are of heavy profile, with stockaded gorges, magazines, &c. r--- In the fourth group are eleven forts (not including the in progress of Fort Meigs), besides the armed battery connected with Fort Carroll. There are, therefore, in the whole system, as it now exists, fifty-three forts and twenty-two batteries. Civil War Defenses of Washington PageC-8 Historic Resources Study Part I-Appendix C

In addition to these, is the small group consisting of Forts Ramsay and Buffalo and intrenchments on Munson's and Perkins' Hills, which do not properly belong to the fortificatioris of Washington. The total armament in the different works, at the date of this report, is six hundred and forty-three guns and seventy-five mortars. The total infantry garrisons required for their defense, computed at 2 men per yard of front perimeter, and 1 man per yard of rear perimeter of works, is about 25,000. The total number of artillerymen (to furnish three reliefs for each gun) required is about 9,000. Aggregate, 34,000. It is seldom necessary to these infantry supports attached to the works. The 25,000 infantry should be encamped in such positions as may be most convenient to enable them, in case of alarm, to garrison the several works, and a force of 3,000 cavalry should be available for duty, to give notice of the approach of any enemy. The artillerymen, whose training requires much time, having learned the disposition of the armament and computed the distances of the ground over which attacks may be looked for, and the ranges and service of their guns, should not be changed. They should remain permanently in the forts. Whenever any enemy is within striking distance of the capital-able by a rapid march to attempt a coup de main, which might result in the temporary occupation of the city, the dispersion of the Government, and the destruction of the archives, all of which could be accomplished by a single day's possession-a covering army of not less than 25,000 men should be held in position to march to meet the attacking column. Against more serious attacks from the main body of the enemy, the capital must depend upon the concentration of its entire armies in Virginia or Maryland. They should precede or follow any movement of the enemy seriously threatening the capital. The Commission do not deem it necessary to enter into a history of the construction of these works, though, fully to appreciate their merits or demerits, that history should be known (as it is presumed to be by those immediately interested), and it is fully given in the engineer's report to the Chief Engineer U.S. Army, dated December 10, 1861. The Commission deem it only necessary to remark that, in general, the lines and locations of works are well chosen; that where the works are not altogether adequate for their positions, or the lines fail to occupy the best ground, the causes are to be found in the exigencies under which the ground was selected and the works built. They find that the defects in the system, arising from these causes, were clearly understood by the engineer, and that on his reassuming charge, in August last, prompt and vigorous measures were taken to remedy them, and that at the date of the examination by the Commission some of fine most serious deficiencies in the line had been remedied; that other works had been laid out or proposed which would judiciously strengthen weak portions of the line, and they learn, from his own statements, that only the impossibility of getting adequate working parties from the troops, and the want of means for hiring the large bodies of laborers which would have been necessary, have prevented the execution during the past season of all the works so proposed. Though from such causes much remains to be done, the Commission find the line throughout its whole extent respectably strong, the works in good condition generally, garrisoned with artillerymen, and the armament in good order, and well supplied with ammunition, and well served. · With these preliminary remarks, the Commission will proceed to mention the individual works, with such recommendations as they deem necessary. Fort Lyon.-This work forms the extreme.left of our line south of the Potomac, and its function is a most important one-that of holding the heights south of Hunting Creek, from which Alexandria could be shelled and our left flank exposed. The work is the largest of all, excepting Fort Runyon. If it had been placed on the higher ground in front of its present position, it would have better fulfilled its object. The engineer is now constructing three advanced works, two on this higher ground and one to command the extensive ravine on the southeast. The Commission further recommend the construction of an interior reduit, by which the main work will be made more secure against assaults; the construction of traverses, particularly on the southern front, and of additional gun platforms, in order, if required, to bring more fire to bear on the heights to the westward. On examining the ground between the Mount Vernon and Accotink roads, the Commission recommend a small work on the spur, with an advanced battery or batteries to sweep the river fiats, the Mount Vernon road, and the ravine before mentioned. This work will better cover the Alexandria Bridge, and give great additional strength to Fort Lyon and to this left flank of our lines. Civil War Defenses of Washington PageC-9 Historic Resources Study Part I-Appendix C

Fort E;llsworth.-This work is well situated, covering immediately Alexandria and the railroad depot. Though a work in second line, it fulfills an important purpose in closing the gap between Forts Lyon and Worth, and sweeping by its fire of rifled guns the approaches to those works, and, uniting its fire with theirs, preventing the establishment of batteries on the heights south of Hunting Creek. The work is amply provided with bomb-proofs and magazines. The Commission recommend platforms and for field guns on the flanks. Traitors' Hill.-This is a very excellent position, forming a point d'ap-pui of the line of obstructions across the valley of Hunting Creek, and commanding the deep ravine which envelopes the rear of Fort Worth. It is important to hold it, and it is valuable as a position for artillery to fire upon the opposite heights; and the Commission recommend that a work be constructed to admit of guns, in conformity to a plan presented by the engineer. Fort Worth occupies a very commanding position. A larger work would have been desirable, but the site would not have permitted it, even if the exigencies of the times in which it was built had not limited the size to a minimum. The work is deficient in fire (and from its figure cannot bring a sufficient fire) upon the heights directly opposite, south of Hunting Creek. Such additional_ guns as its form permits, to bear in this direction, should be introduced. The work has sufficient bomb-proof and magazines. A 100-pounder is being mounted to sweep the sector from Fort Lyon around to Fort Ward. The works previously enumerated, with a chain of obstructions across the valley from Fort Lyon to Cooper's Hill, will secure Alexandria and the left flank of our general defensive line, and, by their powerful artillery, prevent the establishment of field batteries on the heights south of Hunting Creek, and make even the establishment of siege batteries a work of great difficulty and danger. The Commission recommend the introduction of another 100.pounder into this work, to be placed in the salient of the south . Fort Ward occupies a very commanding and important position, defending the Leesburg and Alexandria turnpike and lateral roads, and overlooking the country northwardly and westwardly toward Fort De Kalb and Bailey's and Ball's cross-roads. It contains a sufficient armament and ample bomb-proofs and magazines. It was built in great haste, and with too thin parapets on the exposed fronts. The Commission recommend the thickening of the front parapets to 14 feet, and the construction of , for reversed fires, at the northwest and southwest angles. A 100-pounder is being placed in this work, which will sweep a large extent of country in front of our lines, and, in conjunction with those of Fort Richardson and the batteries north of the Potomac, will furnish a flank fire upon every part of the line hence to Fort De Kalb. Fort Blenker.-The site was selected for its command of the valley of Four-Mile Run. It is defective in trace and in having no view of the approaches from the west, the ground rising in that direction. The latter defect is being remedied by the construction of a seven-gun battery, with stockaded , about 200 yards to the westward. The work being in a re-entrant, and its approaches under powerful fire from Forts Ward and Barnard, it is believed to answer sufficiently well its purpose. The ravine in rear affords much protection to the garrison against shelling, and it is not proposed to construct bomb-proofs. The magazines are adequate. The valley of Four-Mile Run is obstructed by , the rifle-pits only occupying a part of the interval near Fort Blenker. It is recommended to continue the rifle-pits across the valley, and to construct a battery for field guns on the spur east of the fort, by which an important enfilading fire up the valley will be obtained. Fort Barnard occupies a commanding position, and one naturally very strong. It covers the head of ravines, in which large bodies of troops can be collected and concealed in a favorable position for making flank attacks upon an enemy's columns assaulting our line between it and Fort Craig, or attempting to penetrate the valley of Four­ Mile Run. Taken in connection with its outworks and rifle-pits, the ground may be considered well occupied, though the work itself is rather small. Its magazines are adequate, and, considering the protection given to troops by ravines in its rear, it is not considered necessary to build more bomb-proof accommodation. The Commission recommend that casemates, for reversed flank defense, be prepared in the northwestern angle, and that the exterior covert-way be prepared with platforms and embrasures for a battery of field artillery. The works thus far mentioned form a group by themselves, and can scarcely be called "Defenses of Washington," though doubtless having an important bearing on its defense. To defend Washington, strictly speaking, requires simply that the enemy shall be kept off from the banks of the Potomac to such a distance that he cannot shell the city, and this object is accomplished by the chain of works from Fort Scott to Fort De Kalb, resting its left on Four- Civil War Defenses of Washington PageC-10 Historic Resources Study Part I-Appendix C

Mile Run and its right on the Potomac. The works in question are, strictly speaking, for the defense of Alexandria and the railroad terminus. It is unnecessary to expatiate on the importance of holding these points; and these remarks are made to show that the hues of works necessarily embrace something more in their objects than the mere defense of Washington. Fort Scott forms the left interior line covering Washington. That is, in connection with Fort Richardson, it continues the line to the Potomac, thus forming a complete defensive system independent of the works previously mentioned, which cover Alexandria. Its position is important and commanding, and the work is well constructed and provided with ample bomb-proofs and magazines. Under existing circumstances, the Commission do not find cause to recommend any modifications. They would recommend, however, the eventual filling up of the gap between this work and Fort Richardson, by a small work on the elbow of the ridge, and such other additional arrangements as may be necessary to make this interior line complete. Fort Richardson occupies a very commanding position. It is small, but well built, well armed, and amply provided with bomb-proofs and magazines. The ravines in front will be seen by the rifle-pits in construction. A 100-pounder is being placed in this work, which will sweep a sector from Fort Ellsworth to Fort De Kalb. Considering its position (in a re-entrant) and difficulty of access, the Commission do not judge it necessary to recommend the construction of reversed flank defenses. Fort Albany is a work partly bastioned, well built, and in admirable condition, the parapets being turfed and scarps revered with boards. It is well defiladed, and in a very advantageous position to cover the Long Bridge, and look into the gorges of Forts Richardson and Craig. It sees the high ground in front of Fort Tillinghast, and commands the valley between Forts Richardson and Scott. It is well provided with magazines, embrasures, and bomb-proofs. Some heavy rifled pieces are wanted. Fort Runyon.-Though this work has not the importance it first had, it should not have been permitted to fall to decay, nor to be disarmed, as has very improperly been done. As a tete-de-pont, it should be re-armed, and kept in perfect condition in every respect. The five works, Forts Craig, Tillinghast, Cuss, Woodbury, and De Kalb, extend the line from Forts Richardson and Albany to the Potomac, opposite Georgetown, covering what are usually called the Heights of Arlington, heights from which the enemy would have within long range of rifled guns the most important public buildings of the city. The line would have been better had it been thrown half a mile farther forward; but its location where it is, on ground by no means unfavorable, was not an error of judgment, but a necessity of the circumstances under which it was built. In reference to this part of the line, the following general remarks are made: The line south of Fort Richardson, either by magnitude or commanding positions of works, or both, has great strength; if broken, the enemy has yet another line to carry before he can reach the bridges or the heights opposite Washington. If he attempts the left flank of the Arlington lines, by the Columbia turnpike, he takes a line of attack through comparatively low ground, swept to a greater.or less degree by cross-fires or front-fires from Forts Ward, Blenker, Barnard, Richardson, Craig, Tillinghast, and Albany. The route from Ball's ·cross-Roads, approaching the center and right flank of the Arlington lines, is, from the configuration of the ground, not thus closely swept and commanded. It forms the most practicable approach; it leads most directly to the point to be gained. All the ground 1n front, to the distance of a mile, is, however, in fact, swept in flank by the 100-pounders and other rifled guns of Fort Richardson, and of Batteries Cameron and Parrott, at an extreme range of 2 miles, and from the 100- pounder of Fort Ward and the two 100-pounders of Battery Kemble at an extreme range of 3_ miles, while it is under the direct fire, to a distance of at least 1,000 yards of the works (closely contiguous to each other), of the line. The Commission are of opinion that this part of the line needs further strengthening, and recommend the following: 1st. A work at the red house, which shall strengthen the extreme flank of the line on the Potomac, and enfilade the long and deep ravine on the right and front of Fort De Kalb. · 2d. A work on the spur behind Forts Cass and Tillinghast, which shall see into the gorges of these works, give an important fire upon the high ground in front of the line, and flank that line from Fort Woodbury to Fort De Kalb. This work will give great additional strength to Fort Corcoran, enabling it to be held, even should the two Civil War Defenses of Washington Page C-11 Historic Resources Study Part I-Appendix C

works in its front fall, and thus will enable us to maintain a tete-de-pont at the aqueduct, which cannot be held after Fort Corcoran falls. 3d. The construction of batteries for field guns along the intervals of the works, or in the lines of rifle-pits, wherever favorable locations offer themselves. 4th. The construction of sufficient bomb-proofs, to shelter the garrisons of the works named, Fort Corcoran included. 5th. The strengthening of the tete-de-pont at the aqueduct. The Commission also recommend the construction of two works in advance of the line, at points which have been examined and indicated-one opposite the interval between Forts Craig and Tillinghast, the other opposite the interval between Forts Woodbury and Cass, and 700 or 800 yards in front, these works to have stockaded gorges. Fort Ethan Allen.-This is a large work, bastioned on its exposed fronts, and pretty well adapted to its important position. The Commission recommend that a be made to cross the gorge of the west bastion; that the fire on this capital be increased by placing 20-pounder rifled guns in the adjacent flanks, and two of the same class of guns on the pan-coupe of the salient; that additional bomb-proofs be built, so as to furnish sleeping accommodations for one-half the garrison; that the parapets of the northwest front be thickened to 14 feet; that additional platforms be provided for field guns, and that traverses be constructed on the northwest and south fronts. Fort Marey.-Bomb-proofs are in course of construction, as well as additional platforms for guns. The Commission make no further recommendations. The two works just named form no part of the Defenses of Washing ton, strictly speaking, but are of the utmost importance as a tete-de-pont to the Chain Bridge, over which it is indispensable to secure a debouch. The position is strong and well occupied. The lines of rifle-pits which connect the works with each other, and with the banks of the river, afford, with the auxiliary batteries, full view and defense of the numerous ravines, and give all the artificial strength which the position needs. The heights from which the works can be commanded, and the approaches to them, are under the fire of the heavy guns (the 100-pounder Parrott, and rifled 42-pounders and 30- pounder Parrotts, and 32-pounder sea-coast guns) of Batteries Cameron, Parrott, Kemble, Vermont, and of Forts Alexander and Franklin. The Commission suggest that some defensive arrangements are necessary immediately about the head of the bridge; probably two or three small works, or, perhaps, block-houses would suffice. Forts on Upton's, Taylor's, and Munson's Hills.-An army falling back on Washington after defeat, or on account of inferiority of numbers, might find it advantageous or desirable on many accounts to occupy temporarily or permanently this advanced position; its left resting on these naturally strong points, its right on the works at Chain Bridge. On the other hand, should Washington be threatened while held merely by a garrison, these works are too far advanced to be held. We recommend that the existing works be preserved from dilapidation, and consider nothing more necessary. Forts Alexander, Franklin, an·d Ripley.-This group of small works occupies a commanding, but advanced, position. The occupation is in dispensable to the security of the Chain Bridge, and protection of the receiving reservoir. The fires from these works add, at the same time, greatly to the strength of the works and position in advance of the Chain Bridge. The salient position of these works throws them, in great degree, upon their own unaided strength, while there are heights to the northward dangerously near, affording convenient emplacements for the enemy's artillery. The fire from the 100-pounder at Fort Pennsylvania reaches the heights in question; so, too, to a certain degree, that of the rifled guns of Fort Mansfield and adjacent batteries. The fire from the works themselves upon these heights is quite inadequate; the guns (32-pounders) crowded and wholly exposed. The Commission recommend, first, the union of the three works into (essentially) one, by connecting parapets; second, the removal of three 24-pounders now useless, from Fort Ripley, and placing them in battery behind the connecting exterior parapets; third, the building of , to protect all the guns bearing toward the heights mentioned; fourth, the construction of traverses on the southwest faces of Fort Alexander; fifth, the providing of platforms behind the external parapets for at least a dozen field guns to bear upon the heights; sixth, the introduction of another 100-pounder into Fort Alexander or Fort Franklin. (Part of the matters here Civil War Defenses of Washington Page C-12 Historic Resources Study Part I-Appendix C

recommended are in course of execution.) Between these works just named and Fort Mansfield are two well­ constructed and well-located batteries for field guns, for sweeping the ravine in front of Fort Mansfield. Fort Mansfield.-The name is applied to two considerable redoubts and an exterior battery, connected by a substantial rifle-pit. The works are well located, as connecting links between Forts Ripley and Pennsylvania; are well built, and deemed adequate for their purpose. Still another redoubt (not named) is in construction on this line, near the Great Falls turnpike. Fort Pennsylvania.--This .work occupies a commanding position, at a point where the dividing ridge between · the Potomac and Rock Creek narrows so as to expose the slopes in both directions. It commands the three avenues to Washington which unite at Tennallytown. The work, as originally built, was deficient in size; its exposed parapets too thin, and it had not a good view of_the approaches from the northward. A battery for eight guns has been constructed on an advanced point of the ridge (say 300 yards northward), with magazine and inclosed gorge. This is connected with the work by a double line of rifle-pits, with a flanking battery, making of the ensemble a very strong position. The armament of the fort has been increased, and its disposition improved; platforms constructed for additional field guns, and a 100-pounder rifled gun mounted to sweep the sector from Fort Marcy to Fort Massachusetts. The Commission recommend an increased thickness for the parapets of exposed fronts, and the construction of a bomb-proof for garrison. Between Forts Pennsylvania and Kearny is a battery for eight field guns, very substantially constructed, with magazine, but with open gorge. It has good views of the cross valley running from near Fort Pennsylvania to Broad Branch (of Rock Creek), and sees well the ridge of high ground in front of Forts Pennsylvania, Kearny, and De Russy. The Commission recommend that its gorge be closed by a , and extend this recommendation to the different batteries of similar construction between Forts Ripley and Massachusetts. Fort Kearny (recently built), occupying an excellent position, is a necessary connecting link between Forts Pennsylvania and' De Russy. It sees well the upper valley of Broad Branch, and crosses its fires with those of Forts Pennsylvania and De Russy and intermediate batteries upon the dangerous heights in front. It has a powerful armament, and is provided with ample magazines and bomb-proofs, and is well adapted to its location. A field battery, just across Broad Branch, has been built to sweep part of the ravine immediately in front of Fort Kearny; otherwise unseen. Fort De Russy occupies a very commanding point, overlooking the deep valley of Rock Creek, and throwing a cross-fire upon the approaches to Fort Massachusetts, and (together with Fort Kearny)controlling the country roads between the Rockville turnpike and Rock Creek. It is too small, and its fire was inadequate to its position. The site does not admit of an easy extension. This defect is partially remedied by the construction of batteries on either flank, and a few hundred yards to the left, having a better view of the Milk-House Ford road and ravines toward Broad Branch; the other, on the right, sees the slopes toward Rock Creek. The Commission recommend the introduction of a 100-pounder, on center pintle carriage, in place of one of the 32-pounders, to sweep the sector from Fort Pennsylvania to Fort Massachusetts; the fire of which will be particularly important upon the approaches to Fort Massachusetts also; the construction of casemates for reverse fires in the east and west angle of the counterscarp. Fort Gaines is a work in second line. Should the enemy succeed in forcing the interval between Forts Ripley and Pennsylvania, he could not establish himself on the secondary ridge, on which Fort Mansfield is situated, under the fire of this work, by the rifled guns of which the magazines of Fort Mansfield may be exploded. The Commission believe nothing further is required at this work. Batteries Cameron, Parrott, and Kemble.-The first, of two rifled James 42s, the other two of one 100-pounder each, are designed, first, to enfilade the front of the Arlington lines from Fort De Kalb to Tillinghast; second, to operate on the heights between Forts De Kalb and Marcy, <:ar31_911> on which the enemy could plant artillery to bear upon these works, and upon the marginal spurs on which batteries could be established, to bear on the aqueduct or Chain Bridge. Considering how important these functions are, the Commission recommend the substitution of 100-pounders for the rifled 42s in Battery Cameron, and the addition of another 100-pounder to each of the other batteries. Civil War Defenses of Washington PageC-13 Historic Resources Study Part I-Appendix C

Battery Vermont was constructed before the other shor!! of the Potomac was occupied. It has a good view of the Leesburg turnpike, and the Commission recommend the substitution of rifled guns for the 32-pounders, to bear on that approach. Battery Martin Scott sweeps the Chain Bridge. It now contains field 6-pounders. Two 8-inch siege howitzers are recommended. Returning now to the principal line, and proceeding from Fort De Russy eastward, near Rock Creek, on the heights, on the east side, is a battery for field guns, on the line of rifle-pits, intended to command the broad ravine which crosses the interval between Rock Creek and Fort Massachusetts. Fort Massachusetts, in conjunction with Fort Slocum, commands one of the principal avenues of approach to Washington. The original work was entirely inadequate to its important purpose. It has recently been judiciously enlarged, and, with the addition, is a powerful and satisfactory work. The Commission recommend that merlons be raised on the exposed front of the old work, which will, at the same time, defilade the rear and lateral faces; that the parapet of the exposed front be thickened; that bomb-proofs for garrison and casemates for reverse fire at the southeast angle of the old work and at the north angle of new work be constructed. Fort Slocum.-From two-thirds of a mile to 1 mile in advance of Forts Massachusetts and Slocum the country rises to heights say 20 to 30 feet higher than the crests to those works, furnishing to an enemy most advantageous emplacements for artillery. Along the dividing ridge of this high ground, between Rock Creek and the Eastern Branch, leads the Seventh street turnpike road. These two works are, therefore, exposed to the most powerful efforts of the enemy. Fort Slocum, though originally of more respectable dimensions than Fort Massachusetts, was, nevertheless, a small work, and quite inadequate in strength, armament, and bomb-proof. The work is undergoing a considerable and judicious enlargement. The Commission recommend merlons and traverses on the exposed fronts of the old work, by which the work will be defiladed and the guns better protected. The high ground spoken of in advance of these works will be under the fire of the 100-pounders and other rifled guns of Forts De Russy and Totten, besides that of the powerful batteries of the works themselves. Fort Totten occupies a most commanding and strong position, and exercises a powerful influence upon the approaches from the northward and those through the valley between it and Fort Lincoln. It is well adapted to its position, well built and well armed, and amply provided with magazines and bomb-proofs. The 100-pounder here placed will sweep the sector froin Fort De Russy to Fort Lincoln. Merlons and traverses are not called for in this work. The position is so strong that reverse fires are not considered necessary for the ditches. No recommendations made. Fort Slemmer.-A well-placed battery for three 32-pounder guns. No recommendations made. Fort Bunker Hill occupies a very commanding position, but it is deficient in interior space. It should contain at least two rifled guns, and needs additional fire upon its capital. An advanced battery for field guns is designed, with covered approaches or rifle-pits, connecting with the flanks of the work. A covered way would have been a valuable addition, and could have been easily made in the first construction. The Commission recommend a platform for the 8-inch howitzer, to be made in the pan-coupe, and a rifled 30-pounder to be placed on the existing platforms, on each of the two short lateral faces; also a battery for field guns upon the spur to the southward ; also the moving of the two guns on the gorge to more advantageous positions. Forts Saratoga and Thayer are minor works, forming connecting links between Forts Bunker Hill and Lincoln. They are both lunettes, with faces of 100 feet, and stockaded gorges. The first furnishes valuable cross-fires upon the approaches to Fort Bunker Hill, and its situation is commanding. It is desirable that at least one rifled gun should be in this work, and a platform for such a gun is recommended to be made at the, salient. The heavy guns on the flanks should be moved on to the faces, and field guns placed in embrasures substituted. Merlons should be raised on the faces. It is amply provided with bomb-proofs. Fort Thayer is located to command a spacious ravine, which otherwise would afford an ample cover and convenient approach to an enemy. The useless gun on the west-shoulder angle should be moved to the east face, to increase the fire upon this ravine. A platform for a siege gun should be made on the pan-coupe and platforms for field guns on the flanks, and merlons raised on faces. A should be made along the stockade of the gorge. Civil War Defenses of Washington Page C-14 Historic Resources Study Part I-Appendix C

Fort Lincoln is situated on an eminence, overlooking the extensive valley formed by the Eastern Branch and its tributaries, and commanding the Baltimore turnpike, the railroad, and several minor roads, which, passing through or near Bladensburg, lead into Washington. At the foot of this eminence was fought the battle of Bladensburg. The narrowness of the summit, on which it is situated, is unfavorable to a good trace. The exterior batteries and rifle-pits, however, thoroughly see the ground over which assaulting columns must pass, and the bomb-proofs and magazines, arranged as traverses, protect the long and narrow interior from enfilading fires. A 100-pounder is being mounted in the northeast angle, which will sweep the sector from Fort Slocum around to Fort Mahan. The Commission recommend reversed casemates in the northeast angle of counterscarp and a few additional platforms for guns on the western long face. An additional magazine is in construction. From the fort the ridge runs easterly to the Eastern Branch, about three-fourths of a mile distant. About midway is a half-sunk battery for field guns, connected with the work by a double caponiere. At this point the ridge falls abruptly 40 or 50 feet, and the line is continued by rifle-pits to the extremity, where a powerful battery has just been built, terminating this part of our line. A deep, and for three fourths its length impenetrable, ravine takes its origin near the fort, and runs behind and parallel to this ridge. On the spurs immediately south are two half-sunk batteries for field guns, bearing upon the margins of the Eastern Branch. Fort Mahan may be considered an advanced tete-de-pont to Benning's Bridge, and commands the valley of the• Eastern Branch as far as Bladensburg, as well as the immediate approaches to the bridge. It is situated upon an isolated hill, the steep slopes of which are unseen from the fort, and are necessarily defended by external rifle-pits. As long as this work is held, an enemy cannot bring artillery to bear upon the bridge, nor move in force along the road which leads from Baldness-burg to the Navy-Yard Bridge. Between this road and that leading along the summit of the highlands southeast of the Eastern Branch the ground is very much cut up by wooded ravines perpendicular to the direction of the roads. Hence, this single work exercises a powerful influence in preventing an enemy, coming from the direction of Bladensburg, from reaching the margin of the Eastern Branch opposite Washington. It should be capable of holding out for a few days without external aid. The work is well built and sufficiently large. The Commission recommend the construction of bomb-proofs for the garrison, and to contain, besides five days' provisions, reversed casemates at three of the angles of counterscarp and a few more platforms for field guns on east and west faces; also a stockaded , to cover the entrance and flank the gorge. It should be remarked that Benning's Bridge itself is guarded by a tete-de-pont for infantry. The chain of works (ten in all) from Fort Meigs to Fort Greble occupies the summit of the ridge between the Eastern Branch and Oxen Creek from almost all points at which, in this distance of 6 miles, an enemy can bring batteries to bear upon the navy-yard or arsenal. Fort Meigs occupies a key-point to the ridge. It is the extreme point in this direction from which the arsenal and the navy-yard can be seen and reached by an enemy's batteries. To reach this point from Bladens-burg, an enemy must take the Eastern Branch and Benning's Bridge roads, or, by a considerable detour, strike the Marlborough road to the eastward. Obstructed at Fort Meigs, if he would reach the ridge at a lower point, he must make a more extensive detour, cross the valley of Oxen Creek above Fort Meigs, and recross it again; the only public road available being the one ascending the ridge at Fort Wagner and leading to the Navy-Yard Bridge. Fort Meigs should be a work capable of resisting a vigorous assault. It is not so (no isolated small field-work can be so), and no single large work on this difficult ground, even if the topography permitted, can be made so without numerous outworks. The object can only be attained by a congeries of works, which shall sustain and flank each other, and, from numerous points of vie~. see and guard all the ravines and otherwise hidden surfaces. To accomplish this­ to a great degree, at least-several auxiliary works are necessary-say, a work some 300 yards distant, on the Marlborough road (under construction); a battery in connection therewith, near the road, to command a ravine of gentle slopes which extends from near Fort Meigs southward to Oxen Creek; a small work (under construction) on a knob a few hundred yards north of Fort Meigs (of much lower elevation), to see, in reverse, the steep slopes and ravines which approach the fort from the northward. These works, with Fort Du Pont, will form a congeries, which may be considered a single fortification or fortified camp, in which the garrison must sustain itself for a few days. The various ravines and inequalities of the ground furnish ample protection against direct or covered fires, and, as vertical fires are not to be apprehended, bomb-proofs are unnecessary., except for the ground of the forts themselves and for storage of provisions. The guns of Fort Meigs are all sea-coast 32s, and in barbette. As Civil War Defenses of Washington Page C-15 Historic Resources Study Part I-Appendix C

these guns will be useful for their distant fire, the light guns of surrounding works being depended on for flanking purposes, it may be well to let them remain as they are. -Fort Du Pont, after what has been said, requires no especial remark. A deep ravine to the westward may, perhaps, be best defended by a block-house, which can be pretty well screened from an enemy's artillery. The system we have just spoken of may require two or three of these structures. Fort Davis requires no especial remark. It may be regarded as an «58 RR-VOL XXI» to Fort ·Baker, having a pretty good view of approaches on either side of the ridge, not seen from Fort Baker. Fort Baker was designed on correct principles as a strong point on the ridge. Its site is the only one between Forts Meigs and Stanton admitting considerable dimensions. It is a strong and well-armed fort. A ravine near and parallel to its front requires a battery or block-house to guard it. The steep slopes behind it may be well defended by rifle-pits. Additional bomb-proofs are necessary for the garrison. The magazine entrances at this and several other works of this group should be screened by traverses. Fort Wagner is a battery intended to sweep the valley through which the road leads up the heights. Fort Ricketts is a battery intended to see the ravine in front of Fort Stanton, which it does but imperfectly. Fort Stanton occupies the nearest point of the ridge to· the arsenal and navy-yard, and overlooks Washington, the Potomac, and Eastern Branch. It is a work of considerable dimensions, well built, and tolerably well armed. Casemates for reversed fires are recommended in northwest and southwest counterscarp angles, and platforms for two or three rifled guns on the east front. The deep ravine which flanks this work on two sides requires some additional precaution, and further study of it is recommended. Fort Snyder may be regarded as an outwork to Fort Stanton, guarding the head of one branch of the ravine just mentioned. Except additional platforms for field guns, and a ditch in front of the gorge stockade, and block­ houses, nothing further seems necessary. Fort Carroll. --South of the ravine already spoken of, the character of the ridge between Oxen Creek and the Eastern Branch changes. Instead of a narrow ridge, it expands, at a level 60 or 70 feet lower, into a plateau of considerable width. At Fort Carroll this plateau narrows so as to afford a view of both slopes. A spur toward Oxen Creek gives a fine view of its valley opposite Fort Snyder to opposite Fort Greble. This point is occupied by a battery, inclosed at gorge by a stockade. The fort itself is large and well built. The Commission recommend bomb­ proofs for garrisons and provisions, and additional platforms for field guns, and counterscarp casemates for flanking the ditches. Fort Greble occupies the extremity of the plateau. It is a large and powerful work, well provided with magazines and bomb-proofs. The Commission recommend the construction of flanking casemates in counterscarp and additional platforms for field guns. In relation to this group of works, the Commission express the opinion that an enemy wiB not attempt to enter Washington from this direction, and that we cannot (as a general rule) expect to be able to meet him with a line of troops. What is to be prevented is the seizure of these heights for the purpose of establishing batteries to destroy the navy-yard and arsenal. For this purpose the works should be self-sustaining, or relying only upon such aid as a small movable body of troops can furnish, and upon succor, which may be thrown over the Branch after an attack is developed. It is under this view that the considerable increase of strength to Fort Meigs is deemed necessary, and other recommendations are made. Rifle-pits.-A line of rifle-pits commences at Fort Lyon and is continued to the Potomac near Fort De Kalb, interrupted only in the bottoms of Hunting Creek and Four-Mile Run (where obstructions replace it), or occasionally by ground so broken that continuity is not necessary. In this line are frequent emplacements for field guns, openings for sorties, &c. It is not entirely completed. At the Chain Bridge the position is enveloped by a well-arranged system of rifle-pits. The line commences again at Fort Alexander, and continues to the Eastern Branch; from the first-named point to Fort Massachusetts being of dimensions enough to cover entirely a man standing in the trench, and to contain two ranks. From Fort Massachusetts to the Eastern Branch the pits are intended only for one rank. The Commission recommend that the dimensions be increased to admit two ranks. Fort Mahan is surrounded by rifle-pits, and some have been constructed in connection with other works over the Eastern Branch. The Commission recommend the construction of rifle-pits in connection with each work, or system of works, of this group, so as to view and defend its own approaches, a continuous line not being necessary. Civil War Defenses of Washington PageC-16 Historic Resources Study Part I-Appendix C

Wells.-Generally the works are (in some cases at great expense of labor) provided with copious wells. There are yet some, however, where they are wanted, and where they should be provided. Roads.-On the south side of the Potomac there are roads enough, or nearly so; but they require much work, such as widening, raising, constructing of culverts, &c., to make them practicable for winter. A new military road has been constructed from Fort Alexander to Fort Massachusetts, having branches connecting with the different works. The roads along the line thence to Fort Lincoln (partly made by the engineers) make the chain complete. Much work, however, is required on the main stems leading from the city, to make them practicable in the winter. A military road has been made to Fort Stanton; another is in construction behind the ridge from Fort Baker to Fort Meigs, to enable succor to be given promptly to the works. The communications with Forts Carroll and Greble are probably sufficient. It has been estimated that the work on roads about Washington requires ten regiments for twenty days, and efforts have been made to obtain this or an equivalent of labor in some other shape. The Commission further state their opinion that the Defenses of Washington cannot be considered complete without the defense of the river against an enemy's armed vessels. Foreign intervention would bring against us maritime forces, and we could not depend upon being always in superior naval force on the Potomac, and we are, even now, threatened with Confederate iron-clads fitted out in English ports. Fort Washington is too distant for defense of the river under existing circumstances, for the superiority of the enemy in the field, which would drive us behind the Washington lines, would prevent our supporting that work if attacked by land. The Commission believe that a satisfactory defense may be afforded by placing on Jones' Point, near Alexandria, a battery of six guns of the heaviest caliber, say, four 200-pounders and two 15.inch guns in caserriates, and by constructing a battery of ten guns and a covering work on the opposite shore of the Potomac, at or near Rozier's Bluff. An examination has been made, revealing a most favorable and strong position on that side, easily communicated with by water. Surveys are in progress. The occupation of a point on the other shore in this vicinity will likewise protect Alexandria from cannonade, to which it would be exposed if left open to the enemy. The Commission recommend, as an additional security to Washington, the establishment of two heavy guns on Giesborough Point. The Commission conclude their report by expressing their convictions of the great importance of this system of defenses to Washington, and by urging upon the War Department and Congress to take steps and provide means for a full and early completion of the work. The great authority of Napoleon is on record upon the necessity of fortifying national capitals. He gives his opinion that 50,000 men, national guards or volunteers from the citizens, and 3,000 artillerymen will defend a capital against an army of 300,000, and that had Vienna, Berlin, and Madrid been fortified and defended, the countries of which they are the capitals would have been preserved from the fatal results of his campaigns of 1805, 1806, and 1808 against them, and that, had Paris been fortified in 1814, his own Empire would have been saved from overthrow. The position of Washington, on the very borders of the insurgent territory, exposes it to great danger in cases of serious reverse to our arms in Virginia, and twice already have its defensive works been the means of saving the capital and enabling us to reorganize our defeated armies.

Appendix D: Correspondence Concerning Appropriations for the Defenses of Washington

WASHINGTON, December 6, 1861.

Maj. Gen. GEORGE B. MCCLELLAN, Commanding Army of the Potomac, &c.:

GENERAL: It appears probable that our available appropriations will not suffice to complete entirely the defensive works about Washington. Forty-eight different works, some of which, like Forts Ethan Allen, Runyon, and Lyon, are of very large size, extensive abatis, &c., have been constructed, and many of them, besides the usual magazines, are provided with extensive bomb-proofs for quarters. For these constructions the sum of $344,053.46 has been available. It is probable that this sum will not entirely suffice, and that it will be more than exhausted by the close of the present month. I therefore request that an application be made to Congress for the immediate appropriation of the sum of $150,000 for completing the defenses of Washington. You are aware that while hired labor has been extensively employed south of the Potomac, the works north of the river have been almost exclusively constructed by it. I am, very. respectfully, your obedient servant,

J. G. BARNARD, Brigadier-General and Chief Engineer, Army of Potomac.

WAR DEPARTMENT, December 11, 1861.

Hon. SPEAKER, OF THE HOUSE OF REPRESENTATIVES: SIR: I have the honor to transmit herewith a copy of a letter of Brig. Gen. J. G. Barnard, chief engineer of the Army of the Potomac, setting forth the necessity for an early appropriation of $150,000 for completing the defenses of Washington. In view of the urgency of the case, as expressed by the commanding general of the Army in his indorsement submitting the letter to this Department, I commend it to the early and favorable action of Congress. Very respectfully, , Secretary of War. [lnclosure.] Maj. Gen. GEORGE. B. McCLELLAN, Commander-in Chief Commanding Army of the Potomac: GENERAL: By letter of the 6th I requested that an immediate appropriation of $150,000 be asked for "completing the defenses of Washington." I mentioned in that letter that our defensive system thus far consisted of about forty­ eight works, mounting over 300 guns, some of which are of very large size; and I may add that the actual defensive Civil War Defenses of Washington PageD-2 Historic Resources Study Part I-Appendix D

perimeter occupied is about thirty-five miles, exceeding the length of the famous (and hitherto the most extensive fortified by extemporized field-works) lines of Torres Vedras by several miles. The amount which has been expended will not, therefore, considering the pressure under which the works have been built, appear extravagantly large. I now remark that in asking for the sum of $150,000 for "completing the defenses of Washington" I have in my mind the fact that many of the works have been thrown up in the very face of the enemy, and are deficient in profile; and in many other respects the system requires auxiliary works to complete it, which it will probably be deemed advisable to undertake early in the spring. For this reason I have asked the sum of $150,000, but it is not likely that the works now in hand, and for which payments must be made this month, will require more than the balance remaining available. Hence the necessity of an immediate appropriation. I am, very respectfully, your obedient servant,

J. G. BARNARD, Brigadier-General, Chief Engineer Army of the Potomac.

WASHINGTON, October21, 1862.

Hon. E. M. STANTON, Secretary of War: SIR: In applying for authority (as I did about the 1st of September) to expend $50,000 upon the fortifications around Washington, I had not had time to make a thorough study of the matter, and asked this suin to meet the most obvious demand for additional works. An attentive examination of the whole line shows me that much modification and much auxiliary work is necessary in all the works heretofore built. The inclosed extract(*) from a letter from Colonel Kelton, assistant adju-tant-general, will explain this. No work is so indefinite as an extensive system of field defenses like this. There is scarcely a·ny limit to the amount of work which may be bestowed on it, and the practical limit will depend on varying circuinstances and individual judgment. The importance of such a system of defenses for Washington has been so fully demonstrated by events that there need be no argument on this score, and it is quite as clear that if defenses are necessary they must be so adequate, so complete, that in the hour of need they shall be fully equal to what is expected of them. Although they proved the means of saving Washington, they had not been made entirely so up to the time when Washington w,as recently threatened. I now desire, and am expected, to make them so. For this purpose I desire authority to expend to the amount of $100,000 more (should so much prove necessary) from the current appropriation for contingencies of fortifications and field works. I would make a suggestion in connection with this subject. Every one in authority is too busy to give any attention to this matter, and the consequence is that I am the sole judge, all questions therewith being referred to me. . A work involving so great an expenditure, and which is so important to the national safety, should have other authority than the opinion of a single individual, who may be influenced by personal motives. I would, therefore, suggest that a commission of three or four officers, of high rank, be directed to examine into and report upon the subject. I commenced this work as chief engineer of the Anny of the Potomac. When I was again (unsolicited by myself) put in charge of the defenses of Washington, it was at a moment of danger, and I felt the immense importance of bringing these works to the proper condition of efficiency. From previous familiarity, I was probably better qualified than any other to carry on the work. Under this impression, I accepted the task, and have no desire to remain connected with it a day after my services become more valuable elsewhere than here, a matter which it belongs to others to decide. Should the idea of a commission to examine and report upon the defenses of Washington be approved, I would suggest the names of Maj. Gen. N. P. Banks, commanding Defenses of Washington, &c.; Bvt. Brig. Gen. J. G. Totten, chief engineer, U.S. Anny; Brig. Gen. M. C. Meigs, Quartermaster General, and Brig. Gens. G. W. Cullum and W. F. Barry. Such a commission would be the more proper that Congress, at the last session, in making a special appropriation for fortifications of Washington, prohibited that appropriation from being applied to the commencement of any new works. I am, very respectfully, your most obedient,

J. G. BARNARD, Brig. Gen. and Chief Engineer, Defenses of Washington.

ORA, I, 19, Part2 (serial 28), 461-62. Civil War Defenses of Washington PageD-4 Historic Resources Study Part I-Appendix D

WASHlNGTON,December30, 1862.

Hon. E. M. STANTON, Secretary of War:

SIR: I herewith present you the report of the Commission ordered by you to examine the Defenses of Washington, and report to you as to their efficiency, &c. It will be seen that the Commission approve generally of the lines established and of the works, and that they attach very great importance to them; that they recommend some additions to or modifications of the existing works; some new works (five or six) to strengthen certain parts of the line, and that they purpose to add a new feature to the defensive system by the construction of works to defend the river from maritime attack. Their reasons are given in full, and it is not necessary for me to dwell upon them in this place. The amount expended upon the system up to the time when I relinquished the charge last spring to take the field with the Army of the Potomac was about $550,000. This applied to the construction of upward of fifty forts and a number of batteries. Some of these works were of large dimensions, and many had, besides the usual magazine, extensive bomb-proofs, for the protection of the garrisons. Notwithstanding the number of works built, the defensive system was in some parts still very weak, and everywhere there was need (as I stated in a report to the Chief Engineer U.S. Army a year ago) of auxiliary works, more efficient armament, &c.; and I also stated that there were important gaps in the line which should be filled. When the Army of the Potomac retired from the James River, I was ordered to assume the command of the works and troops of Washington, and there was apprehension felt (as the result proved, rightly) for the safety of Washington. Of course, it was my duty, both as engineer and commanding officer, to use the time and means disposable to increase the strength of the defenses. The northern side of the city, between the Potomac and Eastern Branch, which had been little exposed to attack the summer before, was, in August and September of this year, the most likely to be assailed, and from the Potomac to the Seventh street road it was exceedingly weak. When, for want of rank, I was superseded in the command, I continued to discharge the duties of engineer, under the full conviction that in that crisis (September 1) I could render no more valuable service to my country than to perfect the defenses of Washington. I commenced on my first arrival to strengthen this part of the line. I directed the enlargement of Fort Massachusetts, and laid out forts and batteries to make a complete connection between the first-named work and Fort Alexander on the Potomac; at the same time I felled the timber to a distance of a mile in front, thus exposing the ground and making it impracticable to the enemy's movements. On the south of the Potomac, rifle-pits were thrown up between the works, new gun-platforms laid, and the armament improved; obstructions made across the valleys of Four-Mile Run and Hunting Creek; Fort Lyon strengthened by advanced works, and batteries for field guns prepared. On the most prominent or commanding points 100-pounder rifled guns, on center-pivot carriages, were introduced, to bring under fire the whole external area an enemy must occupy in approaching our lines. These, and similar works, are fully described in the report of the Commission. With no other assistance from engineer officers than that of a single officer (valuable, indeed-that of Lieut. Col. B. S. Alexander), it has been necessary to employ a large number of civil assistants, superintendents, and overseers, to supervise the works and troops and laborers employed. This, together with the hire of laborers, the purchase of lumber and other materials, has required a large cash expenditure. You authorized (in August, I think) the application of$50,000 from the appropriation for the contingencies of fortifications, field works, &c.; to the Defenses of Washington, $50,000 more. This last sum will have been nearly exhausted at the end of this month. It is exceedingly difficult to estimate for this kind of expenditure, and as the exigencies of the service have, since my return here, made it impossible to furnish the number of troops required for the labor, I am obliged to suppose that much of the additional work proposed by the Commission will be done by hired labor, and, making reference to past results, to estimate that an additional sum of $200,000 will be needed; for which I ask that an appropriation of Congress be requested. I also request that, until such an appropriation be made, I may be authorized to apply an additional $50,000 from the existing appropriation for contingencies of fortifications. Civil War Defenses of Washington PageD-5 Historic Resources Study Part I-Appendix D

There has been but one other system of field works that I know of that is analogous to this in extent and character-the famous lines of Torres Vedras. These frustrated the design of Napoleon of driving the English from the Peninsula. They consisted of a greater number of works, but the works were smaller, and much less expensive in workmanship; yet on these lines, in a country where labor commanded but one tenth of.what is paid in this country, $1,000,000 was expended from first to last. I am, very respectfully, your most obedient,

Hon. E. M. STANTON, Secretary of War; SIR: On the 30th of December, 1862, I addressed you a letter(*) to accompany the report of the commission ordered by yourself "to examine and report upon the plan of the present forts, and sufficiency of the present system of defenses for the city." * * * * * * * * * * I would add that in asking for all appropriation of $200,000, far the largest part of this sum is required to carry out the recommendations of the Commission, to connect with the system of defenses already established forts and batteries for the defenses of the Potomac. Such works, though of earth and timber, must necessarily be expensive; and, indeed, they should be so carefully planned that hereafter they may be converted into permanent works, if desirable. I am, very respectfully, your most obedient,

HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, May 22, 1863.

Maj. Gen. S. P. HEINTZELMAN, Commanding, &c. : GENERAL: In informing you that on being deprived entirely, as I have been, of the assistance of troops on the south side of the Potomac, I should be obliged to suspend much important unfinished work, I only conformed to a necessity I cannot control. My pay-rolls for hired labor were, for the month· of April, over $30,000, and at the end of that month only $14,000 of the $200,000 appropriated by Congress remained. At the end of the current month, probably not much over$ 10,000 will remain, and I have yet the important works recommended by the Commission appointed by the Secretary of War for the defense of the river to commence, besides the several new works commenced in progress. But it is out of the question to complete all that should be done with hired labor alone. At the Chain Bridge there remains much to be done, and I will continue a force of mechanics, with some laborers, provided I can have the assistance of the troops. Fort McDowell (or fort at the red house) is defensible, and can receive its armament. I shall be obliged probably to defer the construction of bomb-proofs. So at De Kalb, Woodberry, Cass, Tillinghast, a)ld Craig, the thing to be done is the bomb-proofs, and I can do little on these except through the aid of the garrisons. Civil War Defenses of Washington PageD-6 Historic Resources Study Part I-Appendix D

The fort behind Cass requires the labor of 500 men. All I can do is to keep a small force of laborers at work on it. The lines of rifle-pits and batteries are essentially complete. There is some interior work on the different forts from Craig to Mott, but I can do no better than to furnish instructions, supervision, and some assistance to the garrisons. The new works on the river, and those recommended on Traitor's Hill and at Corbett's house. I had expected to do with hired labor, and it is that I may be able to do them that I am forced to withdraw hired labor in great degree from finished works. No one is more tired of this work than I am. The probable allegation that it is endless may be frankly admitted. The works, in the hasty construction and imperfect development given them two summers ago, were certainly a vast addition to the defensibility of Washington, but to make this line, 35 miles Jong, really a strong line, such as we need about Washington, the works of 1861 were but the beginning. The artillery (the best we could get) was improper and not adapted to the purpose or the age. The garrisons need (if a protracted resistance is expected) to be sheltered by a certain amount of bomb-proof; and that these works should be, as intended, the points d'appui for movable troops, it was important that these last should have the protection of rifle-pits and properly located batteries for field guns. Your own observation must have shown you that in the last eight months vast amount of important work has been done, and that there is no comparison between the defensibility of Washington as it was eight months ago and as it is now. It is extremely difficult to keep up a large force of hired laborers, and as to contrabands, of which there are multitudes somewhere, cultivating Arlington or employed by the quartermaster, I have never been able to get any number. I am, very respectfully, your obedient servant,

J. G. BARNARD, Brigadier-General.

HEADQUA.ITTERS CHIEF ENGINEER OF DEFENSES, Washington, July 7, 1863.

Col. J. C. KELTON, Assistant Adjutant-General: COLONEL: In November and December last, a commission of officers, appointed by the War Department, investigated and reported upon the Defenses of Washington, recommending additional works at certain points they deemed weak; the perfection and improvement of other works; and the building of two· water batteries for the protection of the city against naval attack. To carry out these suggestions (approved by the War Department), I asked for and obtained an appropriation of $200,000. The work has been prosecuted with all the vigor the means at my disposal would admit. Although the winter season was most unfavorable for such work, and with the limited amount of money available, as well as with regard to economy, it was not deemed advisable to employ very large gangs of hired laborers, yet, by aid of the troops, working whenever the weather and state of the ground would permit, the most essential works recommended by the commission, such as the advanced works around Fort Lyon; Fort Williams, on Traitor's Hill; Forts Whipple and C. F. Smith, on the Arlington lines; the additional works at the Chain Bridge; the union of Forts Alexander, Franklin, and Ripley into one (Fort Sumner); the completion and construction of Forts Mansfield, Simmons, and Bayard; the · modifications of Forts Reno, De Russy, and Stevens; the extension of Fort Slocum, &c., and the connecting system of rifle-pits and batteries for field guns, were all pressed forward, so as to be in a condition, if not complete, at least of efficiency, for their uses, with the return of the season, when active field operations might throw Washington upon its defenses. Civil War Defenses of Washington PageD-7 Historic Resources Study Part I-Appendix D

The two water batteries were commenced in May, one of them, being out of the line, requiring a very expensive work to render it self-sustaining. My estimates, however (so far as I could estimate at all), were founded upon my previous experience, in which I had been aided freely by troops, and I counted on their aid in doing most of the earthwork and rifle-pits. Instead of this, however, as soon as the season favorable for work actually set in, almost every detail of troops was withdrawn. The extensive system of rifle-pits, incomplete and demanding thousands of men, was left for me to complete unaided. While I was conscious that the appropriation would not by any means suffice to do, thus unaided, all I had expected and was expected to do, I could not blink the necessity of applying it unsparingly to those matters most urgent. I employed 1,000 hired men. When everything depended upon the results of the campaign in Maryland, and an unfavorable result would have brought the rebels upon us in a week, I took off all the force from Rosier's and put it upon rifle-pits and batteries between Rock Creek and Fort Lincoln. About $50,000 of the appropriation now remains. I cannot with this finish what I have in hand. Under the circumstances I have been obliged to expend this .money, I think it proper to ask that $100,000 from the appropriation for "field works" may be made available for the Defenses of Washington. This appropriation is under control of the Engineer Department, but as the chief engineer has no control of field operations, and is not the judge of the necessity of field works of the campaign, I presume the General-in-Chief or the Secretary of War is the proper person to direct its disposition. · Details will be given, if required, as to the importance of continuation. Among other things is the important and expensive work of Rosier's-so important in case of a European difficulty. I am, respectfully, &c.,

OFFICE CHIEF ENGINEER ARMY OF POTOMAC, Washington, D.C., December.IO, 1861.

General J. G. TOTTEN, Chief of Engineers, &c.:

SIR: The resolution of the House of Representatives of July 8, of which the following is the tenor­ Resolved, That the Secretary of War be requested to furnish this House, as soon as practicable, plans and estimates, to be prepared by the Engineer Department, for completing the defensive works on the south side of the Potomac, near this city; and also to report upon the expediency of constructing similar Works of defense on the northern _side of this city, with estimates for the same, so as to reduce to a minimum the number of troops required for the protection and defense of the- capital- having been submitted to me in July last, I now make the following statement: At the time when the resolution was referred to me I was attached to the headquarters of Brigadier-General McDowell as chief engineer, and a few days thereafter I was in the field engaged in the campaign of Bull Run. Previous to this movement the army of Washington, yet weak in numbers and imperfectly organized. under General Mansfield, had crossed the Potomac and occupied the south bank from opposite Georgetown to Alexandria. The first operations of field were, necessarily, the securing of our debouches to the other shore and establishing of a strong point to strengthen our hold of Alexandria. The works required for these limited objects (though being really little towards constructing a defensive line) were nevertheless, considering the small number of troops available, arduous undertakings. Fort Corcoran, with its auxiliary works, Forts · Bennett and Haggerty, and the block-houses and infantry_ parapets around the head of the Aqueduct, Forts Runyon, Jackson, and Albany (covering our debouches from the Long Bridge), and Fort Ellsworth, on Shooter's Hill, Alexandria, were mostly works of large dimensions. During the seven weeks which elapsed between the crossing of the Potomac and the advance of General McDowell's army the engineer officers under my command were so exclusively occupied with these works (all of which were nearly completed at the latter date), to make impracticable the more general reconnaissances and studies necessary for locating a line of defensive works around the city and preparing plans and estimates of the same. The works just mentioned on the south of the Potomac, necessary for the operations of an army on that shore, were far from constituting a defensive system which would enable an inferior force to hold the long line from Alexandria to Georgetown or even to secure the heights of Arlington. On the retreat of our army such was our situation. Upon an inferior and demoralized force, in presence of a victorious and superior enemy, was imposed the duty_ of holding this line and defending the city of Washington against attacks from columns of the enemy who might cross the Potomac (as was then deemed probable) above or below. Undecided before as to the necessity, or at least the policy, of surrounding Washington by a chain of fortifications, the situation left no longer room to doubt. With our army too demoralized and too weak in numbers to act effectually in the open field against the invading enemy, nothing but the protection of defensive works could give any degree of security. Indeed, it is probable that we owe our exemption from the real disaster which might have flowed from the defeat of Bull Run-the loss to the enemy of the real fruits of his victory-to the works previously built (already mentioned), and an exaggerated idea on his part of their efficiency as a defensive line. The situation was such as to admit of no elaborate plans nor previously-prepared estimates. Defensive arrangements were improvised and works commenced as speedily as possible where most needed. A belt of woods Civil War Defenses of Washington PageE-2 · Historic Resources Study Part I-Appendix E

was felled through the forest in front of Arlington and half. sunk batteries prepared along the ridge in front of Fort Corcoran and at suitable points near Fort Albany, and a battery of two rifled 42-pounders (Battery Cameron)was established on the heights near the distributing reservoir above Georgetown to sweep the approaches to Fort Corcoran. Simultaneously a chain of Iunettes (Forts De Kalb, Woodbury, Cass, Tillinghast, and Craig) was commenced, connecting Fort Corcoran and the Potomac on the right with Fort Albany on the left, and forming a continuous defensive line in ·advance of the heights of Arlington. The wooded ridge, which lies north of and parallel to the lower course of offered a position from which the city, the Long Bridge, and the plateau in advance of it could be overlooked and cannonaded. While our external line was so incomplete, it was important to exclude the enemy from its possession. Access to it was made difficult by felling the forest, which covered it (about 200 acres), and the large Junette (Fort Scott) was commenced as soon as the site could be fixed (about the middle of August). The subsequent establishment of our defensive line in advance throws this work into the same category with Forts Corcoran, Albany, Runyon, &c., as an interior work, or second line, but it is nevertheless an important work, as, taken in connection with Forts Richardson, Craig, &c., it completes a defensive line for Washington independent of the extension to Alexandria. The defense of Alexandria and its connection with that of Washington was a subject of anxious study. The exigency demanding immediate measures, the first idea was naturally to make use of Fort Ellsworth as one point of our line, and to connect it with Fort Scott by an intermediate work on Mount Ida. An extended study of the topography for several miles in advance showed that such a line would be almost indefensible. Not only would the works themselves be commanded by surrounding heights, but the troops which should support them would be restricted to a narrow space, in which they would be overlooked and harassed by the enemy's distant fire. The · occupation of the heights a mile in advance of Fort Ellsworth, upon which the Episcopal Seminary is situated, seemed absolutely necessary. The topography proved admirably adapted to the formation of such a line, and Forts Worth and Ward were commenced about the 1st of September, and the line continued simultaneously by Forts Blenker and Richardson to connect with Forts Albany and Craig. Somewhat later the work intermediate between Blenker and Richardson-filling up the gap and having an important bearing upon the approaches to Forts Ward and Blenker and the valley of Four Mile Run-was commenced. The heights south of Hunting Creek, overlooking Alexandria and commanding Fort Ellsworth, had been always a subject of anxiety. The securing to our own possession the Seminary Heights, which commanded them, diminished materially the danger. As soon, however, as a sufficient force could be detached to occupy those heights and protect the construction of the work it was undertaken, and the large work (Fort Lyon) laid out and commenced about the middle of September. Previous to the movement of the army defensive measures had been taken at the Chain Bridge, consisting of a barricade (bullet proof, and so arranged as to be thrown down at will) across the bridge, immediately over the first pier from the Virginia side, with a movable staircase to the flats below, by which the defenders could retreat, leaving the bridge open to the fire of a battery of two field guns immediately at its Maryland end, and a battery on the bluff above (Battery Martin Scott) of one 8-inc.h sea-coast howitzer and two 32-pounders. As even this last battery was commanded by heights on the Virginia side, it was deemed proper, after the return of the army, to erect ·another battery (Battery Vermont) at a higher point, which should command the Virginia Heights and at the same time sweep the approaches of the enemy along the Maryland shore of the Potomac. During the months of May and June the country between the Potomac and the had been examined mainly with the view of obtaining knowledge of the roads and.defensive character of the ground, not in reference to locating field defenses. At the period now in question there was apprehension that the enemy might cross the Potomac and attack on this side. Of course what could be done to meet the emergency could only be done without that deliberate study by which a complete defensive line would best be established. The first directions given to our labors were to secure the roads, not merely as the beaten highways of travel from the country to the city, but also as in general occupying the best ground for an enemy's approach. Thus the sites of Forts Pennsylvania, Massachusetts, Slocum, Totten, Bunker Hill, Saratoga, and Lincoln were rapidly chosen, and works commenced simultaneously at the first, second, third, and sixth of these points Civil War Defenses of Washington PageE-3 Historic Resources Study Part I-Appendix E

early in August.. The.others were taken up as speedily as the clearing of the woods and the means at our disposal would admit, and the gaps in the line afterwards partially filled up by construction of Fort Gaines, Forts De Russy, Slemmer, and Thayer. The works mentioned are at this date essentially completed and armed, though there is still considerable to do in auxiliary arra~gements. Our first ideas as to defensive works beyond the Anacostia contemplated only the fortification of the debouches from the bridges (Navy-Yard Bridge and Benning's Bridge), and the occupation of the heights overlooking the Navy-Yard Bridge. With that object Fort Stanton was commenced early in September. A further examination of the remarkable ridge between the Anacostia and Oxen Run showed clearly that, to protect the navy-yard and arsenal from bombardment, it was necessary to occupy an extent of 6 miles from Berry's place (Fort Greble) to the intersection of the road from Benning's Bridge (Fort Meigs). Forts Greble and Carroll were commenced in the latter part of September, and Fort Mahan, near Benning 's Bridge, about the same time. Forts Greble and Stanton are completed and armed; Forts Mahan and Carroll very nearly so. To fill up intervals or to sweep ravines not seen by the principal works, Forts Meigs, Dupont, Davis, Baker, Good Hope, Battery Ricketts, and Fort Snyder have been commenced, and it is hoped may be so far advanced before the winter sets in as to get them into a defensible condition. The occupation of the Virginia shore at the Chain Bridge was essential to the operations of our army in Virginia. It was only delayed until our force was sufficient to authorize it. General Smith's division crossed the bridge September-, and Forts Ethan Alien and Marcy were immediately commenced and speedily finished. A few weeks later (September 28) the positions of Upton's and Mun-son's Hills and Taylor's Tavern were occupied and Fort Ramsay commenced on Upton's Hill. The enemy's works on Munson's and the adjacent hill were strengthened and a Junette built near Taylor's Tavern. Comprised in the foregoing categories there are twenty-three field forts south of the Potomac, fourteen field forts and three batteries between the Potomac and Anacostia, and eleven field forts beyond the Anacostia, making forty-eight field forts in all. These vary in size from Forts Runyon, Lyon, and Marcy, of which the perimeters are 1,500,937, and 736 yards, down to Forts Bennett, Haggerty, and Saratoga, &c., with perimeters of 146, 128, and 154 yards. The greater portion of them are inclosed works of earth, though many-as Forts Craig, Tillinghast, Scott, &c., south of the Potomac, and Forts Saratoga, Gaines, &c., on the north-are lunettes with stockaded gorges. The armament is mainly made up of 24 and 32 pounders on sea-coast carriages, with a limited proportion of 24-pounder siege guns, rifled Par-rott guns, and guns on field carriages of lighter caliber. The larger of the works are flanked; but the greater number are not, the sites and dimensions not permitting. Magazines are provided for one hundred rounds of ammunition, and many of the works have a considerable extent of bomb­ proof shelter, as Forts Lyon, Worth, and Ward, in the bomb-proofs of which probably one-third of the garrison might comfortably sleep and nearly all take temporary shelter. In nearly all the works there are either bomb­ proofs like the above, or log barracks, or blockhouses of some kind. It would be impossible to go into any details about these constructions. I am in hopes ultimately to be able to deposit in the Engineer Office drawings of each work with sufficient detail for most purposes. The accompanying sheets, Nos. l and 2, will exhibit the general location and bearings of the works.(*) The tabular statement herewith will show the perimeters, number of guns, amount of garrison, &c.( +) It should be observed that most of the works south of the Potomac, having been thrown up almost in the face of the enemy, have very light profiles, the object having been to get cover and a defensive work as speedily as possible. The of all the works, with few exceptions, are surrounded by abatis. It is impossible, at present, to indicate the exact extent of forest cut down. (The drawings herewith represent the forest as it existed before the works were commenced.)(++) The woods in advance of Forts Worth, Ward, and Blenker have been felled; all surrounding and between the next work on the right and Fort Richardson; all the wood on the ridge on which is Fort Scott-a square mile probably-in advance of and surrounding Forts Craig, Tillinghast, and Woodbury, besides large areas north of the Potomac, &c. This fallen timber (most of which still lies on the ground.) rendered an enemy's approach to the lines difficult. The s.ites of Forts Totten, Slocum, Bunker Hill, Meigs, Stanton, and others were entirely wooded, which, in conjunction with the broken character of the ground, has made the selection of sites frequently very embarrassing and the labor of preparing them very great. Civil War Defenses of Washington PageE-4. Historic Resources Study Part I-Appendix E

The only case in which forts are connected by earthworks is that of Forts Woodbury and De Kalb, between which an infantry parapet is .thrown up, with emplacements for field guns. The construction here was suggested by the fact that this was on one of the most practicable and probable routes of approach for tlie enemy. Infantry trenches have, however, been-constructed around or in advance of other works, either to cover the construction (as at Fort Lyon), or to see ground not seen by the work (as at Forts Totten, Lincoln, Mahan, &c.). The works I have now described do not constitute a complete defensive system. We have been obliged to neglect much and even to throw out of consideration important matters. We have been too much hurried to devise a perfect system, and even now are unable to say precisely what and how rriany · additional points should be occupied and what auxiliary arrangements should be made. It is safe to say that at least two additional works are required to connect Fort Ethan Allen with Fort De Kalb. . The necessity of protecting the Chain Bridge ·compelled us to throw the left of our northern line several miles in advance of its natural position, as indicated by the topography to the sites of Forts Ripley, Alexander, and Franklin. Between these and Forts Gaines or Pennsylvania one or two intervening works are necessary. Between Forts Pennsylvania and De Russy at least one additional work i.s necessary. Fort Massachusetts is entirely too small for its important position. Auxiliary works are necessary in connection with it. Small tetes-de-pont are required around the heads of Benning's and the Navy-Yard Bridges. Between Forts Mahan and Meigs one or more intervening works and between Forts Du Pont and Davis another work of some magnitude are required, the ground along this line not being yet sufficiently known. A glance at the map will show it to be almost a continuous forest. It is not deemed necessary to connect the works by a continuous line of parapet, but the intervening woods should be abatised and open_ground traversed by a line of artificial abatis, and infantry parapets, half:sunk batteries, &c., piaced so as to protect these obstructions and to see all the irregularities of the ground not now seen from the works. Considerable work is also required in the way of roads, the amount of which I cannot state with any precision. Several miles of roac,ls have actually been made. The works themselves would be very much strengthened by caponieres in the ditches, additional internal block-houses, or defensive barracks, &c. The aggregate perimeter of all the works is about 15,500 yards, or nearly 9 miles, including the stockaded gorges, which, however, form a small proportion of the whole, requiring, computed according to the rule adopted for the lines of Torres Vedras, 22,674 men (about) for garrisons. The number of guns, most of which are actually mounted, is about four hundred and eighty, requiring about 7,200 men to furnish three reliefs of gunners. The permanent garrisons need consist of only these gunners, and even in case of attack it will seldom be necessary to keep full garrisons in all the works. The total garrisons for all the works (one hundred and fifty-two in number) of the lines of Torres Vedras amounted to 34,125 men; and as the total perimeters are nearly proportional to the total garrisons, it appears that the lines about Washington jnvolve a magnitude of work of about two-thirds of that in the three lines of Torres Vedras. The works themselves, fewer in number, are generally much larger than those of Torres Vedras, and involve, I believe. when the amount of bomb-proof shelter in ours is considered, more labor per yard of perimeter; but the latter lines involved a greater amount of auxiliary work, such as the scraping of mountain slopes, palisading, abatis, roads, &c., than we have had occasion to make. The lines of Torres Vedras were armed with five hundred and thirty-four pieces of ordnance (12, 9, or 6 pounders, with a few field howitzers); ours with four hundred and eighty pieces, of which the greater number are 32-pounders on barbette carriages, the rest being 24~pounders on the same carriages, 24-pounder siege guns, 10, 20, and 30 pounder rifled guns (Parrott), with a few field pieces and howitzers. As to number of guns, therefore, our·armament approaches to equality ·with that of the famous Hnes mentioned; in weight of metal more than doubles it. The above applies to our works as now nearly completed, and has no reference to the additional works I have elsewhere mentioned as hereafter necessary. It is impossible to give any other statement of actual cost of the Civil War Defenses of Washington PageE-5 Historic Resources Study Part I-Appendix E

works than the total amount expended thus far. The work has been done partly by troops and partly by hired laborers, the works north of the Potomac being· mostly done by the latter. The large amount of carpentry in magazine frames and doors and blindages, barrier gates, , block-houses, defensive barracks, &c., has kept a large gang of carpenters all the time at work, and caused a iarge expenditure for lumber. The entire amount made available by the Department for these works has been $344,053.46, and this will all have been expended (or more) by the end of the present month. This would give an average of a little over $7,000 for each of the. forty-eight works; but of course the real cost of them has been very unequal. · The importance of perfect security to the capital of the United States in the present state of affairs can scarcely be overestimated, and these works give a security which mere numbers cannot give, and at not a tithe the expense of defense by troops alone. It is impossible to make anything like a reliable estimate of what additional amount of funds will be required. In a letter to the General-in•Chief commanding Army of the Potomac, of December 6, I urged an immediate appropriation of $150,000, and this appropriation has been asked for of Congress by the Secretary of War. Should the auxiliary works which I have suggested be undertaken and the scarps be revetted, I believe a larger sum than this may be judiciously expended. I therefore recommend that an additional $100,000, or $250,000 in all, be provided for the continuation and completion of the defenses of Washington. These works acquire new importance if the probability of a foreign war is taken into consideration. In view of this new importance, of the semi-permanent or possibly permanent necessity for such works, it is proper to suggest that early in the spring the scarps be protected by a timber or thin brick revet-ment, and the exterior and other slopes, where not already done, be sodded, and that wooden caponieres, or counterscarp galleries, be arranged to flank all unflanked ditches-at least of important works. The strengthening of the profiles where necessary has already been mentioned as important. It remains with me to express my sense of the zeal and efficiency with which the officers of engineers serving with me since April have discharged their duties. T9 their energy and skill I am mainly indebted for the successful accomplishment of this really great work, and I feel that I have a right to say that for the safety of the capital in the hour of its greatest danger; for saving the cause of established government and the Constitution from the most serious blow the rebels could have inflicted, the country owes much to the labors of the engineers. From their great experience and constant association with me since April the services of Colonels Woodbury and Alexander have been particularly important in the laborious reconnaissances and in directing the execution of extensive lines of works. General Wright laid out and superintended the construction of Fort Ellsworth, and General Newton, who since the 1st of September until recently had charge of the works below Four Mile Run, laid out and directed the construction of Fort Lyon. Captains Blunt and Prime, Lieutenants Comstock, Houston, McAlester, Robert, Paine, Cross, Babcock, and Dutton have served with efficiency during the whole or part of these constructions, and the lamented Snyder lost his life from over-zealousness in discharge of his duties while in impaired health from his services at Charleston Harbor and . Since the relief of Captain Prime, Lieut. H. L. Abbot, of the Topographical Engineers, has taken his place, proved himself a most energetic and valuable assistant, having completecl Fort Scott and built Forts Richardson and Barnard. In carrying out so many works at the same time, and for organizing and managing the large bodies of hired laborers employed, it has been found necessary to call in the aid of civil engineers, not only because the engineer officers were too few to keep proper supervision, but because a large portion of those under my orders have been called off to other duties, such as the organization of bridge trains, the instruction of engineer troops, &c. Civil Engineers Gunnel, Frost, Faber, Childs, and Stone have rendered valuable services; also Mr. (now major of the Fifteenth Volunteer Regiment) Magruder. I should also express my warmest acknowledgment to Mr. James Eveleth, of your office, who, as clisbursing agent and paymaster of the large bodies of hired laborers, has performed an amount of duty I should hardly have expected from one individual. I could wish that the law under which he serves the Engineer Department, might be so modified in his case as to enable him to receive some adequate compensation for the extra duties he has voluntarily assumed. I Civil War Defenses of Washington PageE--6 Historic Resources Study Part I-Appendix E

should have mentioned, in connection with my statement of the amount actually expended, that the Treasury Department has advanced over $20,000 on account of the defenses of Washington, which should be refunded. I feel it my duty in this place to urge that Congress should take immediate measures to assess the land and other damages arising from these works and from the occupation of troops. In most cases the owners are ill able to bear temporarily the losses to which they have been subjected. In conclusion, I would add that to the great importance attached io these works by the commanding general (now Commander-in-Chief), to his valuable suggestions and prompt and cordial co-operation, the present state of efficiency of the defenses of Washington is in no small degree due. I am, very respectfully, your obedient servant,

ALEXANDRIA, VA., March 29, 1862.

Col. D. B. SACKET, Inspector-General, U. S. Army :

COLONEL: Agreeably to orders, with Colonel Tyler, Fourth Connecticut Volunteers, I proceeded to inspect the following forts on the south side of the Potomac: I. Bamard.-Armed with eight guns, as follows: Three 32-pounders; one 24-pounder barbette; one 24- pounder siege; one 30-pounder Parrott, and two 8-inch sea-coast howitzers. The armament, ammunition, parapets, slopes, and abatis in good order. 2. Fort Richardson.-Nine guns, as follows: Two 24-pounder barbette; three 24-pounder siege guns; two 30- pounder Parrotts, and two IO-inch siege mortars. One of the mortars is unserviceable from its trunnions being too large for the bed. One magazine leaks slightly. In other respects fort in good condition as to guns, ammunition, parapets, and abatis. 3. Fort Albany.-Twelve guns, as follows: Eight 24-pounder barette; two 6pounder field, and two 24- pouilder howitzers. The guns and ammunition and abatis in good condition. The sides of the ditches by caving in has made the parapet so thin in some places as to be of no protection from the shot of the ordinary guns used in service. 4. Fort Craig.-Seven guns: Five 24-pounder guns and two 24-pounder siege. Guns, ammunition, parapets, and abatis in good order. 5. Fort Tillinghast.-Seven guns: Three 24-pounder siege; one 20-p·ounder Parrott; two IO-pounder Parrotts, and one 2A-pounder field howitzer. All of the above-named forts are just being occupied by the Fourteenth Massachusetts Volunteers, Colonel. Greene. Not yet being fully in possession, the gunners could not be exercised. The armament, ammunition, parapets, and abatis of Fort Tillinghast" are in good order. 6. Fort Cass.-Five guns: Two 24-pounder siege guns; two 20-pounder Parrotts, and one 24-pounder field howitzer; garrisoned by a company of Heavy Artillery, Lieutenant Ward. 74 strong. Guns, ammunition, parapets, and abatis in good order. Men well instructed. The captain of this company has been absent since after the battle of Bull Run on sick report, and now nominally on recruiting service, though not getting any recruits, except three, during a period of several months. Lieutenant Ward has brought the company to a very fine state of discipline and efficiency, and it would be to the interest of the service if Capt. A. J. Langworthy were discharged the service. Civil War Defenses of Washington . PageE-7 Historic Resources Study Part I-Appendix E

7. Fort Woodbury.-Five guns: Two 24-pounder barbette; two 24-pounder siege, and one 24-pounder field. howitzer. This fort is not garrisoned, having an ordnance sergeant and two sentinels. The slopes are caving in. One of the magazines is flooded with water, the ammunition all being stored in the other one. The guns, ammunition, and abatis in good order. 8. Fort De Kalb.-Nine guns: One 24-pounder barbette; four 24-pounder siege; two 24-pounder field howitzer, and two 24-pounder flanking howitzers. No garrison; an ordnance sergeant and two sentinels. Slopes washing; guns, ammunition, and abatis in good order. All of the above-named forts being now newly occupied, or the garrisons soon to take possession, will require definite instructions, which will be required in writing, as verbal instructions, If not repeated periodically, are of little weight. An artillery officer should have a general supervision of these forts, who should see that the instructions are obeyed, and he should make written reports that stated inspections are made, noting the condition of material and works and efficiency of garrison. These works are in general good condition for field works, considering the season of the year; well armed and supplied with ammunition. The proper manning of these works and their efficiency in case of attack will depend on the officers having the future charge of the troops occupying them. The works are good and well armed. I am, sir, very respectfully, your obedient servant,

N. B. SWEITZER, Lieutenant-Colonel and Aide-de-Camp.

WASHINGTON, October 6, 1862.

Col. J. C KELTON, Assistant Adjutant-General:

COLONEL: I am informed, by Captain Sawtelle, that probably about 500 contrabands can be obtained from Fort Monroe. I desire them very much for work on the fortifications of Washington, and request that, if consistent with other requirements of the service, they may be ordered here at once. There are steamers at Fort Monroe, by which they can be brought up immediately. As everything connected with this subject of the fortifications of Washington is left to my individual will, I take this occasion to state what I am doing, and what, I think, is required. Before the battle of Bull Run, the idea of the fortifications of Washington was not broached, the works previous to that (Forts Ellsworth, Runyon, Albany, and Corcoran) being for special purposes. Imperfect, as a system of defense, as those works were, they doubtless exercised an important influence in deterring the enemy from following up his success by an assault upon Arlington or Alexandria, and the necessity of completing the fortification of .Washington became evident. · It was an immense undertaking, for the line to be held was 35 miles long, through a country extensively wooded and of intricate topography. The work was not fully inaugurated until the latter part of August, and its extension around the northern sides of the city, and over the Eastern Branch, was of later date. During, therefore, the five months of August, September, October, November, and December, the entire defensive line, 35 miles in length, consisting of about fifty different works, and mounting four hundred and forty-three guns, was, though not completed, essentially brought to the condition in which it was left when the Army of the Potomac commenced its campaign in Virginia. It is no matter of surprise that a work which, to be thoroughly well done, required so much preliminary study and reconnaissance and which was execuied under the pressure of an enemy in our front, allowing no time for such thorough study, should be found in many respects imperfect; besides, it was necessary to commence works in many cases before the woods could be cleared away enough to give that perfect knowledge of the ground essential to their best location. As the season of construction drew to a close, the sense of danger to the capital in great measure passed away, and,in making an appropriation to meet liabilities actually incurred, Congress prohibited the application of that appropriation to the . commencement of any new works, although there were several gaps to be filled, and much work necessary on some parts of the line to give them any real defensive strength. On resuming charge of these works, in August last, the condition may be briefly stated as follows: On the south side of the Potomac there were probably works enough, and the woods had been pretty well cleared from the front. A few auxiliary batteries have been judged necessary, as well as the connection of the works by rifle-pits ·or infantry parapets. A remark should be made about Fort Lyon. It is a very large work, and a very important one. In its location there were Civil War Defenses of Washington PageE-10 Historic Resources Study Part I-Appendix E

many conditions to be fulfilled, more than were reconcilable. There is now a most serious defect, which is, that over the readiest approach of an enemy the ground is not seen beyond 200 or 300 yards. I consider it absolutely necessary to remedy this defect, and it can only be done by building lunettes in advance, which I am now doing, or, rather, about doing. At the Chain Bridge extensive clearing of woods, rifle pits, auxiliary batteries, &c., have been found necessary. The most defective part of the line, and it was one the most liable to attack during the recent demonstrations of the ~nemy-was from the Potomac to Fort Massachusetts. The left was occupied by a cluster of three small works, Alex-under, Franklin, and Ripley. The turnpikes from Great Falls, Rockville, and Brookville, uniting at Tennallytown, were commanded by Fort. Pennsylvania, and an intermediate point and road was held by Fort De Russy. The country is very broken, and was thickly wooded, the woods having been cleared only in the immediate vicinity of the works. At present the woods have been cleared. Two additional forts, se~eral batteries, have been built and are in progress, and a road of communication is likewise in progress. From Fort Massachusetts to the Eastern Branch the line of forts might be considered complete, though it may be determined to enlarge Fort Slocum. Fort Massachusetts itself, the earliest work of this line, was entirely inadequate to its most important position. It has been extensively enlarged. The country in from of this position was more open than usual, but it has been found necessary to fell large quantities of timber. Rifle-pits and some additional batteries have been constructed. The portion of the Jines over the Eastern Branch is the least satisfactory of the whole, particularly that portion from Fort Meigs to Fort Stanton. The topography was very hard to deal with, and, unfortunately, the works were located before the woods were cut. The works, serving very imperfectly the approaches, and surrounded by woods, were nearly indefensible. One of the first measures I took was to order a regiment there for clearing. This was to a considerable extent, done, but while my attention has been directed elsewhere, the work of clearing has been suspended. As the enemy cannot enter the city from this direction, the object of the works is to prevent him seizing these heights, and occupying them long enough ·to shell the navy-yard and arsenal. For this, the works must be made secure against assault, and auxiliary to this object is the construction of roads by which succor can be readily thrown to any point menaced. Some general remarks will apply to the whole line. When these works were commenced, neither field nor siege guns could be obtained in any adequate numbers; hence the only resource was to arm them with sea-coast 24's and 32's from the arsenal. It always appeared to me objectionable, and I regret that, even in the absence of other guns, I permitted so many guns of this character to be mounted. These guns can only be used upon the enemy's batteries or troops at a distance. At close quarters not only are they too unmanageable, but, with all expedients used for protection, they are too exposed to permit the men to stand by the guns. In many of the works, such as Forts Pennsylvania, Totten, Lincoln, &c., the objection is not so strong, as the artillery is mainly intended for distant action. But in others, such as Forts Ripley, Franklin, Meigs, &c., it is a most serious evil. I have not investigated the subject thoroughly, but it is probable that, many of these guns should be dismantled and it is certain that a great many emplacements should be prepared for field and siege guns. Applying these remarks to the whole line, it is probable that two hundred platforms should be made, embrasures cut, &c., for field or siege guns, which earthwork included, is alone a very considerable work. If the enemy attack Washington, it will be with a large force and numerous artillery. He will concentrate upon the point of attack a large number of pieces that the garrison should not be exhausted or driven out by shells, adequate bomb-proof shelter should be provided. This is already done to a great extent, but there are yet probably one-half or one-third of the works where such shelter is needed. This is a heavy and expensive work. To obviate further-or rather, to prevent as much as possible­ the concentration of the enemy's artillery, I am placing in secure positions, such as Fort Ellsworth and Fort Alexander, inn the heights near Battery Cameron (already constructed and armed with rifled 42-pounders, for the same purpose), JOO­ pounder Parrott guns, to sweep the ground where such concentrations are most likely and dangerous. The preservation of these works is another important consideration. The winter acta severely upon these earthern scarps and exterior slopes. Much repair is now needed. It has not yet been made, owing to the pressure of other matters. Perhaps it will be best to revet all the scarps and timber. Presuming that none now doubt the necessity of maintaining an adequate defensive line around Washington, I have thrown together these remarks that the commanding general and the War Department may be better able to understand the actual condition and the requirements, that the existing defensive line shall be adequate, as well as to explain the considerable works of different kinds I have ordered since my return, and what I propose to order. I am unable to estimate what expenditure will ultimately be made, probably $100,000. J.G.BARNARD, Brigadier-General.

WASHINGTON, March 31, 1863. Maj. Gen. S. P. HEINTZELMAN; · Commanding Department of Washington: GENERAL: I herewith send a tabular statement(*) of armament, garrisons, &c., of the forts constituting the Defenses of Washington. Also a statement of the length of lines of rifle-pits.(*) Also a statement giving a list of batteries for field guns, indicating their location and the number of guns they will receive.(*) Drawings will be made and sent to you, which will indicate the position of these rifle-pits and batteries, as also of all the forts. It will be seen that the total of full garrisons for all the forts is 26,725 men, of which 10,305 consists of artillerymen and 16,420 of infantry. These garrisons are apportioned as follows: Location. Artillery. Infantry. Total. Fort Lyon position 890 · 1,260 2150 From Fort Ellsworth to f:ort Corcoran 3,315 4,730 . 8,045 Chain Bridge position 600 1,000 1,600 Potomac to Eastern Branch 3,500 5,700 9,200 Over Eastern Branch 2,000 3,730 5,730 Total 10,305 16,420 26,725 It is a matter of some difficulty to say with any precision what additional troops are necessary to hold Washington, as it would depend much upon the circumstances and force of the attack, and also upon the condition of the Potomac. It may be stated, in the first place, that besides the full garrisons at the Chain Bridge, there should be, when the enemy is, or can be, near enough and strong enough to attack in any force, an additional infantry force there (with some cavalry) of about 2,000 men, making, say, 3,600 in all. With this force, the rifle-pits can be sufficiently manned to resist a strong attack. Should an attack be protracted, or should an enemy appear before the position in force, about 4,000 more men, and at least three field batteries, would be required for a protracted resistance. The rifle-pits of the position are 3,500 yards (say 2 miles) long, but here, as elsewhere, it will be never necessary to man the whole length. A considerable portion of those between Fort Ethan Allen and the Potomac, for example (behind the ravine), would be sufficiently guarded by two companies, as it is almost unassailable, and needs only to be carefully watched. At Fort Lyon and outworks there should be permanently, I think, a force equal to the full garrisons (2,150 men), and, if the enemy's movements or positions are such that he can throw himself in force upon this «12 R R-VOLXXV, PT II» position, 1,000 men, in addition, should be added to guard the rifle-pits about 1 mile long); and this latter number may need to be increased from the reserves in case of a prolonged attack. The artillery garrisons of all the forts should be kept full. I have calculated for three reliefs of gunners for all the guns. This provides for contingencies, and the artillerymen are counted as part of the garrison, as all not serving guns would be subject to man the parapets in case of assault; 10,305 men are necessary for this purpose. There should be at least infantry enough to fill up all the.garrisons of all the works south of the Potomac; to supply an additional 1,000 men at Fort Lyon, and 2,000 at the Chain Bridge, and a reserve of 15,000 men, besides 2,000 or 3,000 cavalry and eight or ten batteries of artillery, making 35,000 men in all, besides cavalry and field artillery; and this is the very lowest estimate for defense, under the most favorable circumstances, as will be seen hereafter. If the enemy was in front of Washington in force, and the Potomac was low, we might expect him to threaten both siqes, and it would be necessary to have the works between the Potomac and Eastern Branch fully garrisoned. Finally, should he establish himself in force on the north side of the Potomac, we might expect formidable assaults upon the works over the Eastern Branch, unless they were fully garrisoned. In general, however, the defenses of part of the works might be safely trusted to their artillery garrisons. The following extract from the report of the commission ordered last autumn by the Secretary of War to report on the Defenses of Washington may be interesting: Civil War Defenses of Washington, PageE-12 Historic Resources Study Part I-Appendix E

The total infantry garrison required for their defense, computed at 2 men per yard of front perimeter, and 1 man pei- yard of rear perimeter of works, is about 25,000. The total number of artillerymen (to furnish three reliefs for each gun) required is about 9,000. It is seldom necessary to keep these infantry supports attached to the works. The artillerymen, whose training requires much time, having learned the disposition of the armament, and computed the distances of the ground over which attacks may be looked for, and the ranges and service of their guns, should not be changed; they should remain permanently in the forts. The 25,000 infantry should be encamped in such positions as may be most convenient to enable them, in case of alarm, to garrison the several works, and a force of 3,000 cavalry should be available for outpost duty, to give notice of the approach of any enemy. . Whenever an enemy is within striking distance of the capital, able by rapid march to attempt a coup de main, which might result in the temporary occupation of the city, the dispersion of the Government, and the destruction of the archives, all of which could be accomplished by a single day's possession, a covering army of not less than 25,000 men should be held in position, ready to march to meet the attacking column. Against more serious attacks from the main body of the enemy, the capital must depend on the concentration of its entire armies in Virginia or Maryland. They should precede or follow any movement of the enemy seriously threatening the ·capital. You will observe that from Hunting Creek north to the Potomac there are about 11,000 yards of rifle-pits. As observed elsewhere, it will never be necessary to man the whg)e at once. Take that part between Hunting Creek and Four-Mile Run, for example. There are 5,100 yards of rifle-pits connecting the works, but the actual front before which the enemy could arrange his line of battle will not be more than 2, JOO yards. He will not mass his men in the valleys, or on the slopes of the valleys of these streams,. where they would be seen and cut up by plunging and cross­ fires of our forts. He may try their flanks with small columns, favored by darkness, &c., and they would be resisted by the fire of the forts, and by a few men holding the pits until reserves could be brought up. Let it be supposed that the total of 35,000 men were provided, and that the enemy attacked our lines on the south side; of these 35,000, there would be appropriated as artillerymen for all the works, 10,300; for complement of infantry, to make up full garrisons for all the works south of the Potomac, 7,000; for additional supports to Fort Lyon and Chain Bridge position, 3,000; making a total of 20,300. This force would hold our two flanks at Fort Lyon and the Chain Bridge strongly, and would distribute along the line of forts from Ellsworth to Corcoran, as artillerymen and supports, 8,045 men, of which the infantry supports would be posted near the works, and need not be shut up in them except in case of actual assault. There would remain 15,000 men, of which 4,000 might be in reserve at Arlington, 2,000 men where the Military road crosses Four-Mile Run, and 4,000 or 5,000 near the toll-gate, on Alexandria and Leesburg turnpike, leaving but 4,000 or 5,000, and such portions of the cavalry not employed in patrolling, and portion of the field artillery as a general reserve north of the Potomac, the works of which would only be held by their artillery garrisons. It will be seen, therefore, that a force of this magnitude would not furnish a satisfactory defense against a powerful and prolonged attack. It would be necessary to sustain it by arming all the able-bodied men in the District, and putting them upon the lines and in garrisons in the northern forts, and even then the defense would be weak. If the river was low, and the enemy held both shores, the necessity of more troops would be still more apparent, and it would be unsafe to mention a less number than 50,000 or 60,000 men as sufficient to make a good defense, and this last number coincides nearly with what the commission thought necessary to hold and cover the city in case an enemy is within "striking distance," and even then they would rely only upon the concentration of our entire armies "for ultimate security against more serious attacks from the main body." The tabular statement of armament, garrison, &c., gives the number, caliber, and character of guns in the works.(*) In those few cases where the guns are not on hand, the figures are entered in red; so also are the names of two or three forts not actually commenced, or as yet not materially advanced. Most of the guns wanting can be supplied at short notice from the Arsenal, as soon as the works are ready to receive them. It should be remembered that the commission recommended a strong work on Rozier's Bluff, opposite Fort Lyon, to defend water batteries on the left bank of the Potomac; a water battery on Jones' Point, below Alexandria, and two Civil War Defenses of Washington Page E-13 Historic Resources Study Part I-Appendix E

works in advance of the Arlington lines, none of which are included in the statement. They would probably require in all 2,000 more men. The figures representing actual garrisons at this date are the numbers of "enlisted men" present at the work. While in some few cases (as at Fort Corcoran) there are more than required as artillery garrisons, in others there is a deficiency. The rifle.pits south of the.Potomac require but a very short period of good working days to be completed, with the force now detailed for that purpose. At the Chain Bridge they are completed; at Fort Lyon, nearly so. From the Potomac to Eastern Branch the line has been run through, but it is proposed ultimately to enlarge the part from Rock Creek to the Eastern Branch. This, with good weather, would require a regiment a couple of weeks to do. I understand from General Barry that there are on hand in the forts 100 rounds of ammunition per gun, and sometimes more, except for the 100-pounders, for which ammunition is now being supplied. The statements as to number of guns required for new or old works are not regarded as final and exact. There is indetermination on these points and others in some few eases. J. G. BARNARD, Brigadier-General, &c.

HEADQUARTERS OF ARTILLERY, U.S. ARMY, Washington, May 18, 1.864. Maj. Gen. H. W. HALLECK, Chief of Sia.ff:

GENERAL: I have the honor to transmit herewith a· report of the inspection of the defenses of Washington, made by order of the Secretary of War. I am, general, very respectfully, your obedient servant,

A.P.HOWE, Brigadier-General, Inspector of Artillery.

HEADQUARJ'ERS INSPECTOR OF AITTILLERY, Washington, May 17, 1864. Major-General HALLECK, Chief of Staff: Civil War Defenses of Washington PageE-18 Historic Resources Study Part I-Appendix E

SIR: In compliance with the directions of the Secretary of War, received on the 29th ultimo, I have made an inspection of the works in the defenses of this city, and beg leave to submit the following report of the inspection: My time being broken by court duties, I was unable to make but little progress in the inspection until the 10th instant, and since that time the movement of troops within the line of defenses has somewhat embarrassed the completion ·of the inspection. The character and strength of the troops garrisoning the different forts, their discipline, drill, and efficiency, the kind and extent of the armament, the condition and supply of the magazines, ammunition, and implements are found in this report under the names of the respective forts. After a careful examination of the line of works I am of the opinion that they are ample in their engineering and artillery strength for the purpose for which they were intended-the defense of Washington. The works on the south side of the Potomac may be divided into three classes: First, those which immediately cover approaches to the city, and are within artillery command of the city; second, those which cover approaches, and are beyond the range of artillery command; third, those which do not cover approaches to the city, and are beyond the range of artillery from the city. Of the first class, which I regard as the most important, are the works extending from Fort C. F. Smith on the right to Forts Richardson and Scott on the left, inclusive. The consecutive works in this line are within close artillery support of each other and with good field of fire. Forts Corcoran, Whipple, and Albany, Bennett, Haggerty, and Runyon are interior works of this class, Forts Whipple and Corcoran being of the first importance, having a strong command over five of the works in the front line. Fort Runyon is out of repair, and is at present unoccupied. It holds, however, an important position, being at the head of Long Bridge, and if occupied would hold the bridge and guard it from a surprise. I recommend that it be put in order and occupied. The exterior works of this class are connected with a strong earthen epaulement, and extending along the line of works to the Potomac on the left, with embrasures for light artillery at favorable points. If this class of works is held, it is not; in my judgment, in the power of an enemy seriously to annoy Washington with a fire from the south side of the river. With an artillery strength of men sufficient to develop the fire of the forts, and a proper support of infantry, I am of opinion that the works cannot be carried by an assault. The weakest feature in this line of works, and it obtains more or less throughout the whole line of the defenses, is their liability to be surprised. The garrisons of the works, with the exception of small guards, are quartered outside the works. No infantry force has been kept between and near the line of the works. The outpost guards have been very weak. The character of the topography of the country for miles outside of the works, with the numerous roads, all favor and invite a sudden and covered dash upon the works. With a view to strengthen the works in this particular, I recommend that regiments of the [Veteran] Reserve Corps be stationed at the following points: One regiment between Forts Richardson and Craig; one regiment between Forts Craig and Tillinghast; one regiment between Forts Tillinghast and Woodbury and in advance of Fort Whipple; one regiment between Forts Woodbury and Strong and in advance of Fort Corcoran; one regiment between Forts Worth and Ward; one regiment between Forts Garesche and Berry, and one regiment between Forts Ethan Allen and Marcy. From the troops of the Reserve Corps thus posted I recommend that the officers commanding the defenses south of the Potomac be instructed to establish outposts as follows: A picket reserve of three companies at Ball's Cross-Roads; a picket reserve of three companies at Bailey's Cross-Roads; a picket reserve of two companies on the Little River pike, between Clover Hill and Hunting Creek; a picket reserve of two companies on the Leesburg and Georgetown pike at the cross-roads, between Langley and Fort Marcy. I recommend that the best instructed and most efficient artillery troops in the line of defenses be kept in the works of the first class. Forts Ethan Allen and Marcy, in the second class, cover the approaches to the city by the Chain Bridge; they are in close artillery support of each other, but beyond the range of artillery support from the nearest work (Fort Smith) on their left. If the cover of these works and their connections are properly. manned it is believed they cannot be carried by assault. From the position of these works they do not offer advantages sufficient to an enemy, if possessed, to make them worth the operations of a siege; they do not immediately command the bridge, and the right bank of the river at the head of the bridge is commanded by Batteries Vermont, Cameron, Kemble, and Parrott on the left bank, and the bridge is swept by Battery Martin Scott on the left bank. The strength of artillerymen at Battery Civil War Defenses of Washington Page E-19 Historic Resources Study Part 1-Ap'pendix E

Martin Scott I do not consider sufficient. I found .but I non-commissioned officer and 3 men in charge of four guns. I recommend that I officer, 4 noncommissioned officers, and 24 men be allowed this battery. The works of the third class, extending to the left from Fort Berry to the Potomac, do not immediately command approaches to the city, and are beyond artillery range from it. They, however, command important ground, and cover the depot at Alexandria, and are in good supporting distance; and they are sufficiently strong, if properly manned, to resist an assault. The possession of them would offer no objective point to an enemy that would render them liable to a siege. Battery Rodgers, below Alexandria, and Fort Foote, on the left bank of the river, are important works for river defense. Battery Rodgers received ammunition for its two guns on the 9th instant, and Fort Foote ammunition for its 15-inch guns on the 13th instant. From the length of time that is necessarily occupied in serving guns of the c·aliber in these two works, and the unfavorable heighth of these batteries above the water-line for accuracy of firing, the guns of the two works do not afford sufficient reliable fire as would insure the checking of an attempt to pass the batteries. I would, therefore, recommend that these two works be furnished with the full armament for which they are constructed, and that they be manned by efficient artillerists. The works on the north side of the Potomac are a continuous line of forts from Fort Sumner, on the river above the city, to Fort Greble, on the river below the city. The forts in this line are in artillery support of each other, and connected.throughout by earthern epaulements. Fort Gaines is an interior work. The most important position of this line is that part included between Forts Sumner and Slocum, as it covers the approaches to the city on the river line of roads. The most important works in this portion of the line are Forts Stevens, Reno, Sumner, and Slocum. The portion of the line between Fort Slocum and the Eastern Branch is less liable to be assailed, and that portion of the line east of the Eastern Branch the least liable to attack of any part of the whole defenses. The most important works between Fort Slocum and the Eastern Branch are Forts Lincoln, Bunker Hill, and Totten. · The most important works east of the Eastern Branch are Forts Stanton, Carroll, and Greble, which, from their position, are in range of the Arsenal and Navy-Yard, and Fort Stanton in easy command of both. With a view to guard these works from a surprise, I recommend that regiments of the Reserve Corps be stationed at the following points: One regiment between Forts Sumner and Mansfield, one regiment near Fort Reno, one regiment near Fort Stevens, one regiment between Forts Slocum and Totten, one regiment between Forts Lincoln and Bunker Hill; the officer commanding the division north of the Potomac to establish a picket-line from this force. The cavalry force at the fords of the Potomac, beginning at Great Falls and extending to the Monocacy, is sufficient, as is the force on the south side to guard the railroad. The forts throughout the line are advanced to completion, sufficient for defensive purposes, except Forts Ward and Stanton, in which I found but few guns mounted, and the work on them progressing but slowly. · The guards at the different bridges I think have been insufficient, and the guard duty generally loosely and carelessly performed. This has arisen in some degree from the guards being composed of detachments of companies and commanded by non-commissioned officers. I recommend that the following changes be made in the guards at the bridges: One full company at , at the head of Long Bridge; one full company at the new stockade at the head of Aqueduct Bridge; one full company at the Georgetown head of the Chain Bridge, with a guard of 10 men and 2 non-commissioned officers from this company at the iron gates of the bridge; one platoon of a company at the Navy-Yard bridge, and the other platoon of the same company at the upper bridge of the Easiem Branch. The performance of the guard duty as required by the regulations of the service should be rigidly enforced. There is no communication between the forts by signal, nor between the outside and the forts. Signals are made from the outside of the works directly to department headquarters, and from .thence to headquarters of the division south of the Potomac by telegraph. I recommend that signal communication be had between the outside and the forts, and between the forts. The roadways within the line of defenses are ample and sufficiently good for praEtical purposes. Subsistence is readily obtained from the depots in the line, and twenty days' kept on hand in the works south of Hunting Creek and at Forts Ethan Allen and Marcy. The other works keep ten days' supply on hand. I am of opinion that it would promote the health, discipline, drill, and efficiency of the Reserve Corps to encamp them Civil War Defenses of Washington PageE-20 Historic Resources Study Part I-Appendix E

without the Jim.its of the city, but within the line of defense, leaving in the city only guards for hospitals, public property, and provost duty. I recommend that they De encamped at the following.points: One camp near Fort Gaines, one camp between Batteries Cameron and Vermont, one camp between Fort Scott and Fort Craig, one camp near Alexandria Seminary. These points are favorable for reserves and are accessible from all points of the line, and would afford advantages to the troops for improvement that they cannot have within the limits of the . city. I observed in the inspection, too, generally, a want of observance of the regulations of the service which requires the marking of clothing, knapsacks, canteens, and haversacks. This omission was very marked in the Second and Seventh New York Regiments. The Ninth New York Heavy Artillery was changed during the insp~tion from the north to the south side of the river, and I inspected it in the works previously occupied by the First Connecticut. I regret to state that I found this regiment, in point of discipline and drill (both in artillery and infantry), much less efficient than any regiment in the line of defenses. The men of this regiment are generally young, ac.tive, and intelligent men, and the fault lies mainly with the commanding officer of the regiment, Colonel Welling. The condition of the regiment bears unmistakable evidence that the colonel of the regiment is not fit for the command. Fort C. F. Smith, Maj. W A.

Respectfully returned. General Howe's suggestions and remarks are excellent and should be carried out both as regards the disposition of troops and outposts and the maintenance of the works. The liability to surprise has long been appreciated by the engineers, who have, as far as possible, been engaged in providing flanking arrangements to such as were most important and exposed. It has long been the intention to repair Fort Runyon, but pressure of work elsewhere has prevented. I do not concur in the importance of Fort Greble at present. It is particularly liable to surprise, can with difficulty be flanked, and while Fort Carroll is held its site cannot be occupied by the enemy. Fort Carroll is being strengthened and flanked, as also Forts Stanton and Meigs. It was to concentrate the garrisons and Civil War Defenses of Washington PageE-28 Historic Resources Study Part I-Appendix E

diminish the danger of surprises that I recommended the suppression of Forts Davis, Du Pont, Wagner, Ricketts, and Greble. The Ordnance Department will furnish the complete armament of Fort Foote and Battery Rodgers as soon as it is able. I do not concur in the opinion that these batteries are too high; indeed, I consider that the latter is too low. J. G. BARNARD, Brigadier-General, &c.

HDQRS. DEPT. OF WASHINGTON, 22D ARMY CORPS, Washington, D. C., July 29, 1864.

Maj. Gen. H. W. HALLECK, Chief of Staff, &c.:

SIR: In compliance with your instructions of the 27th instant, I called together yesterday General De Russy, General Hardin, Lieutenant-Colonel Haskin, and Lieutenant-Colonel Alexander, for the purpose of consultation as to what additional armament of field pieces it may be desirable to place in the forts defending the city. We find that the armament of these works was settled by a board of officers convened for that purpose by orders from the Secretary of War, dated November 9, 1863.(*) The works have been arranged in accordance with the report of this board, and to make any material changes in the armament would rc::quire changes in the platforms or embrasures, involving considerable work, and be likely to produce confusion in the ammunition, besides introducing to the garrisons pieces with whose ranges they would be unacquainted. For these reasons we do not think it will be judicious to disturb the armament of the works at the present time, nor do I suppose that such was your intention in calling my attention to the fact that it might be well to place in the forts some additional field pieces, it being understood, however, that these pieces are to be used in almost every case in the exterior batteries to the right and left of the forts. It is true that some of the forts, particularly Fort Reno, ought to have some additional field guns for use in the fort, when the enemy approaches within short range, but the theory upon which the defense line is arranged is Civil War Defenses of Washington PageE-29 Historic Resources Study Part I-Appendix E

that all, or nearly all, the additional guns that may be required in case of an investment, or even an assault, are to be placed in the batteries to the right and left of the forts, all the principal forts being supported and generally flanked on both sides by batteries placed in commanding positions. It has been supposed that these field guns would be brought into the defenses by an army retreating before superior numbers, but from our recent experience we have seen that the enemy may succeed in appearing before our works before this additional artillery, or even the troops, can get here. Such being the case, it may be well to inquire whether some of the more important batteries on the line of defense ought not to be armed at once, or. field pieces, with ammunition, placed in the forts ready to arm them, and hold the enemy in check, for some days, at least; in order to give time to re-enforce the garrison of the city. Having the officers whom I have mentioned to advise me, I thought it well to look into the whole subject in order that we might have an understanding, :and put on record what additional field guns it will be well to have on hand, and where they should be placed on the approach of the enemy at any future time. The following is the result of the consultation on this subject: LINENORTII OFTHECTIY. .Fort Sumner.-To have additional field pieces; two to be placed on the line of the conduit to hold the bank between Fort Sumner and the river; two in Battery Benson, on Powder Mill Branch, and two in Fort Sumner, or Battery Alexander, as may. be required. Fort Simmons.-Six field pieces to be added; two to be placed in Battery Bailey, on Powder Mill Branch; two in Battery Mansfield, and two held in reserve, or placed in the batteries between Fort Simmons and Fort Bayard. Fort Reno.-Should have four additional field pieces to complete the armament. In case of attack two or three light batteries should at once be sent to this important post, taking position at first on the ridge between Tennallytown and Fort Gaines. Battery Rossell.-Being an inclosed work with a magazine, and occupying an important position on the right of Fort Reno, should be armed with two field howitzers, 24 or 32 pounders, and four 12-pounder field guns. Fort Keamy.-There should be four light field guns added to this fort to arm Battery Terrill. Battery Smead.-There should be four field pieces added to this work; two of them to be placed in the baitery on the left near Broad Branch. Fort De Russy.-There should be six light pieces added to this work, to be placed in Battery Kingsbury, and in a battery now under construction, overlooking the bridge on Rock Creek. Fort Stevens.-In case of threatened attack there should be two field batteries here (twelve pieces), one of them to be a mounted battery. These pieces are to arm"the batteries between Rock Creek and Piney Branch, including Battery Sill. Fort Slocum.-There should be six field pieces sent to this fort, to arm the batteries on the right.and left of the fort. Fort Totten.-The fort itself is sufficiently armed. The four light pieces are to arm the battery on the left. There ought to be two additional pieces to arm the battery on the right. Fort Slemmer.-Four field guns are required to arm the batteries on the right and left. Fort Bunker Hill.-There should be eight light pieces added to the armament of this work for the battery in front, and the batteries on the right and left. Fort Saratoga.-There should be six light pieces added to this fort, to arm the batteries on the right and left. The new redoubt (not named) between Fort Saratoga and Fort Thayer should be armed with four field pieces. Fort Thayer ought to have four field pieces to arm the batteries between it and the railroad. Fort Lincoln ought to have six additional field guns to arm the exterior batteries, beginning on the left at the railroad and ending on the right at Battery Jameson, on the Eastern Branch, making for the line north of the city, eighty-eight additional field guns. Over the Eastern Branch.-The board to which allusion has been mad~ had substituted field pieces for many of the barbette guns with which these forts had first been armed, and they are generally well supplied with small guns. Since that time, however, Fort Foote has been completed, and extensive additions have been made to Forts Stanton and Carroll. These being the most important works on this line, it seems proper that they should be sufficiently armed. Fort Foote requires two 24-pounder, flank defense howitzers, one 12-pounder mountain howitzer, four 12-pounder Napoleons. Civil War Defenses of Washington PageE-30 Historic Resources Study Part I-Appendix E

Fort Stanton requires one 32-pounder howitzer, two 4 1/2-inch rifled guns, four 12-pounder howitzers, two 12- pounder Napoleons. Fort Carroll requires one 32-pounder howitzer, two 30-pounder Parrotts, six 12-pounder howitzers, making for the line over the Eastern Branch twenty-five additional pieces. SOUTH OF THE POTOMAC,

Forts Marcy and Ethan Allen.-There ought to be six field pieces added to the armament of each of these works, to be used in the adjacent batteries in case of threatened attack. ·Two additional (mounted) batteries should be sent to this ·position in case the enemy appears in force. · Fort C. F. Smith is sufficiently armed, but in case of a threatened attack the batteries on the north side of the river, flanking this work, should be armed, the north battery with two IQ-pounder Parrotts, and the south battery with two Napoleon guns. · Fort Craig ought to have four long guns, 30-pounders, or 4 1/2-inch guns for the batteries on the right and left, and six Napoleon guns for the battery at the Columbia turnpike and the adjacent batteries on the right and left. Fort Barnard requires two-12-pounder Napoleons for the exterior battery. Fort Ward.-There should be added to this work twelve light guns. Four to guard the Leesburg turnpike north of the fort, and the remainder for the batteries toward Fort Worth.' Fort Williams ought to have eight additional light pieces to arm the batteries, two on the right and two on the left. Fort Willard requires four additional field guns for the adjacent batteries to the right and left of the work. Fort Jackson, at end of Long Bridge, ought to have two light guns, making for the line south of the Potomac fifty­ four additional guns, and for all the works around the city 167 additional guns. It is not supposed that all of these guns can now be obtained. I propose, therefore, only to send requisitions for those which seem to be in-dispensable- say field guns. · For Fort Reno and Battery Rossell, 10 guns; Fort De Russy, 6 guns; Fort Stevens, 6 guns; Fort Saratoga and the new redoubt, 6 guns; Fort Lincoln, 6 guns; Fort Stanton, 9 guns; Fort Carroll, 9 guns; Fort Foote, 7 guns; Forts Marcy and Ethan Allen, 6 guns: Fort Craig, 6 guns; Fort Ward, 6 guns; Fort Williams, 4 guns; Fort Willard, 2 guns; Fort Jackson, 2 guns; making 75 guns. As the enemy cannot approach the city in all directions at the same time, it is hoped with due watchfulness that we may with the additional field guns now asked for so arm any point of attack as to hold the enemy in check until the city can be re-enforced with the necessary additional troops and batteries. In this conviction I cannot withhold the remark that our works are strong in themselves and strong in their armaments, but forts and cannon, ev_en if Gibraltars, cannot of themselves defend a city against an enemy. In case the enemy attack us we will also require soldiers.

Appendix F: Supplement to Commission Report

HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, October 14, 1863. Hon. E. M. STANTON, Secretary of War: • SIR: A Commission having been ordered by you a year ago, to examine into the system of the defenses of Washington, and that report having received your approval, I feel it proper to make a brief statement of the operations on the works and their condition. Previous to my resumption of charge of these works in August, 1862, the system was but a skeleton, so to speak, of a fortified line. In many important parts, indeed, though the works would be valuable as points-d'appui to a line of battle, they would be almost useless unless in connection with an army strong enough to be capable of giving battle. Washington required something more than this. Washington required to have all the strength that could be attained from a line of field-works; a strength which would enable it to be defended with a moderate force against very superior numbers, at the same time furnishing to an inferior or defeated army, forced to take refuge within its lines, an impregnable barrier. In accordance with this idea, I immediately commenced operations, which were approved and confirmed by the commission. I give a brief sketch. Fort Lyon.-Four out-works, Forts Willard, O'Rorke, Farnsworth, and Weed, have been completed and armed, and auxiliary batteries and rifle-pits connect them. The position now is a very strong one. Fort Williams.-On Traitor's (Cooper's) Hill, has been built, also rifle-pits and batteries between it and Ellsworth. With a few pieces of field artillery in these batteries and the opposite one near Fort Lyon, and some watchfulness, a cavalry raid into Alexandria would be difficult, while they complete the system of defense against regular attacks. Battery Garesche, a small fort, has been built near Fort Blenker. It is armed and efficient. Fort Berry, occupying an important point between Forts Barnard and Richardson, has been built and armed. Fort Whipple.-This powerful work, one of the finest field-works in the world, was commenced in the spring, and had its batteries ready early in June. It is now essentially complete. Fort C. F. Smith, commenced last winter, was in readiness early this spring. It is a powerful work, and is essentially complete. The various works on the line south of the Potomac, from Fort Lyon to Fort C. F. Smith have, with few exceptions, undergone important modifications and improvements. In Forts De Kalb, Craig, and Tillinghast, large bomb-proofs have been made (all the new works, except Berry, have extensive bomb-proofs), and in all, new embrasures and platforms have been made, magazines strengthened, &c. The works have been connected by rifle-pits (more properly covered ways for infantry), and at all points where artillery could be advantageously used, batteries for field guns have been constructed. Forts Ethan Allen and Marcy (at Chain Bridge).-These works have been extensively repaired and improved, and large additional bomb-proofs built. They are connected and supported by covered way rifle-pits, and batteries for field guns arranged where necessary. Fort Sumner.-The three works, Franklin, Ripley, and Alexander, have been combined into one powerful work of this name. Forts Mansfield, Simmons, and Bayard have been built between Sumner and Reno. Fort Reno (formerly Pennsylvania) has been extensively modified, bomb-proofs added, and the powerful battery in advance constructed. Connecting the works mentioned (from Sumner to Reno) are Batteries Benson and Bailey, and several others, and lines of covered way rifle-pits. Fort Kearny, a powerful work, has been built between Reno and De Russy, as also Batteries Russell, Smead, Terrill and covered way rifle-pits. Civil War Defenses of Washington Page F-2 Historic Resources Study Part I-Appendix F

Fort De Russy.-Modified and improved. Between it and Fort Stevens, the Batteries Kingsbury and Sill and lines of rifle-pits have been constructed. Fort Stevens (formerly Massachusetts) has been extensively enlarged and improved. Between it and Fort Slocum three new batteries and lines of rifle-pits have been constructed. Fort Slocum, originally one of the weakest, has become one of the largest and most powerful works on the line. Between Forts Bunker Hill and Saratoga, Saratoga and Thayer, Thayer and Lincoln, numerous batteries for field· guns have been built and constructed and supported by lines of rifle-pits. Fort Lincoln has had additional bomb-proofs built. The spur or ridge between it and the Eastern Branch has been occupied by the powerful Battery Jameson, and by rifle-pits arranged as covered ways. Fort Mahan has been strengthened by the construction of bastionets, for flanking. Fort Meigs has been extensively enlarged. All other works not mentioned have, with scarce all exception, received considerable improvement and modification. On nine different points having the most extensive command, 100-pounder Parrott guns have been mounted so as to bring every part of the ground in front of our line under their fire. Two new batteries, Parrott and Kemble, were built expressly for such guns, and their special function is, with Battery Cameron, to sweep the heights across the Potomac between the Chain Bridge and Fort C. F. Smith. For the defense of the Potomac, the two water batteries (Battery Rodgers and Fort Foote) have been constructed. They are essentially finished, and are receiving their armament. The latter is a powerful inclosed work, and the most elaborate in its internal arrangements of all the defenses of Washington. The work described is either finished or brought to a state of efficiency; still a system of works of this character demands constant watchfulness and expenditure to keep it up, and there are yet some works that require overhauling, and all of them ought to have their scarps either revetted or sloped and sodded. Fort Ward, in particular, a very important work, was built in great haste, and demands almost complete rebuilding. It is a maxim among railroad men that "when the cars can go over the road it is half done." Tum-outs have to be made, depots, store-houses, offices, &c., have to be built. The track must be ballasted, tunnels, cuts, and embankments enlarged, and, finally, a second track must be laid. It is quite likely that this maxim will apply fully to the works about Washington. They are, essentially, brought to a condition to render the services expected of them, as a railroad over which the trains begin to pass is brought to a condition to do the service expected of it, and, like the railroad, it is likely to tum out that they are really but half finished. I have just before indicated, in general terms, how much I can foresee that ought to be done, besides which there will, doubtless, arise innumerable demands for repairs and removal of what was hastily and imperfectly built in the first place, as well as for modifications and improvements. I have no disposition to magnify this work. I am ready to leave it at any moment. I relinquished command and the more exciting duties of the field at a moment when they would have brought me more palpable recompense, to carry out these works, because I felt that the security of Washington demanded their perfection, and that the security of Washington meant the security of the nation's cause, and that I was the man upon whom the duty fell. With these remarks, I recommend that an appropriation be asked of Congress of $300,000, for completing and rendering more permanent the defenses of Washington . .I am, very respectfully, your most obedient, J. G. BARNARD, Brigadier-General, &c.

WASHINGTON,D.C., October4, 1864.

Brig. Gen. R. DELAFIELD, Chief Engineer. Washington:

SIR: I have the honor to submit the following report of operations on the defenses of Washington during the year ending September 30, 1864: These defenses, as now constructed, consist, in the aggregate, of 60 inclosed forts, having an aggregate crest of 25,799 yards, with emplace. ments for 956 guns, and of 93 batteries, having emplacements for 491 guns, and of 35,711 yards of infantry parapet or covered way; to which should be added about 33 miles of military roads, which have been built for purposes of communication where the existing roads of the country would not fulfill that purpose. A mere statement like this of the number of these works will convey some idea of the magnitude of undertaking to defend a great city, when it is essential to preserve it on account of its being the seat of Government, containing the Government machinery, from the long-range guns of modem artillery. And such a statement will be apt to convey to all unmilitary minds the idea of enormous strength, a strength vastly greater than we actually possess. It should be borne in mind that these works are stretched out over a long line, some 37 miles in extent, inclosing the cities of Washington, Georgetown, and Alexandria, and that we have, in most cases, only a single line of defense, which, if once forced by an enemy, we have nothing between him and the public buildings and archives but our reserves, with the chances of battle in the open field. This consideration ought to show us the 'necessity of making this line strong one; and if it does not suggest an additional interior line of defense, it will, at least, convince us of the necessity of having at all times, when there is a possibility of attack, the forts well garrisoned with practiced artillerists and a strong reserve within the defenses. In other words, if we should be attacked by a powerful army, Washington City would become, in a military sense, not a walled city with gates, but a great intrenched camp, requiring a large army for its defense, the defensive works standing for a certain number of men, enabling, perhaps, all other things being equal, 25,000 men in them to repel the attacks of 50,000, or 50,000 to repel 100,000, or 100,000 to repel 200,000. With these remarks, I proceed to a report of the work on the defenses during the past year. I will first take up the defenses south of the Potomac. These consist of thirty-one forts, having an aggregate crest line·of 12,504 yards, with emplacements for 540 guns, and 42 batteries, having emplacements for 229 guns, and 20,869 yards of rifle­ pits or covered way for infantry. This includes only work now essentially completed or ready for its armament, and does not embrace work partially completed or in contemplation. The present actual armament is 377 guns and 36 mortars. The work done during the past year-or from October 1, 1863, to September 30, 1864 best be detailed by taking up each fort separately. Fort Marcy: The front parapet has been,raised and newly revetted, new platforms and embrasures made, terre­ plein graded and paved, gutters laid, new magazine made, abatis repaired, and the interior of the fort sodded. Fort Ethan Allen: The abatis has been removed, most of the embrasures newly revetted with , platforms repaired, and a new bomb-proof 230 feet long has been built; the southwest bastion has been cut off from the main work by a line of stockade, with gateway; one of the old magazines has been rebuilt, and a new bomb-proof guard­ house constructed. Fort C. F. Smith: This work, nearly completed at date of last report, has been completed and sodded. Fort Strong: A new bomb-proof 280 feet long has been constructed, parapets re-enforced and newly revetted,. scarp built up from bottom of ditch on 45 degrees slope, three new traverses built, and the interior of fort sodded, and new platforms and embrasures made. Fort Woodbury: Parapets re-enforced, scarp built up on 45 degrees slope; new bomb-proof constructed 150 feet long; new magazine and new filling-room constructed, and three traverses made and interior rebuilt. Fort Cass: Parapets have been re-enforced, scarp built up on 45 degrees slope, new embrasures and platforms made, one traverse built and new bomb-proof seventy-two feet long put up, old flankers tom down and caponiere put in stockade gorge. Fort Tilllinghast: Parapets re-enforced, scarp built up on 45 degrees slope, new interior revetment put up, embrasures and platforms repaired; bomb-proof commenced at date of last report has been completed, two new traverses built, Civil War Defenses of Washington Page F-4 Historic Resources Study Part I-Appendix F

two magazines rebuilt, abatis renewed, flankers torn down, and two for flanking stockade gorge put up, and interior of fort sodded. Fort Craig: Parapets re.enforced, new interior revetment put up, abatis renewed; bomb-proof commenced at date of last report has been completed, two new traverses built, interior of fort sodded, two flankers torn down, and two redans for flanking put up in stockade gorge. Fort Richardson: The scarp of this work has been revetted with plank, and sodding repaired. Fort Berry: A new bomb-proof guard-house has been built and fort sodded. Fort Barnard: Scarp has been revetted with plank, new magazines built, embrasures newly revetted with gabions, and sodding repaired. Fort Reynolds: Interior revetment has been repaired, and embrasures newly revetted with gabions. Battery Garesche: A new traverse has been built. Fort Ward: This fort has been torn down and newly constructed and enlarged to nearly twice its original size; three new magazines and two new filling or implement rooms have been built, all serving as traverses; one bomb­ proof 208 feet long has been built, and another of same length is in course of construction. The new fort is now nearly completed, and is one of the strongest works on the defenses. Fort Ellsworth: The old bomb-proofs and traverses have been torn down, two new magazines have been built, and a new bomb-proof 160 feet long is in course of construction and nearly completed. Forts Lyon, Weed, Farnsworth, O'Rorke, and Willard: Interior revetments have been repaired, crests sodded, embrasures revetted. Portions of the exterior slopes of the four latter works have been sodded. Battery Rodgers, nearly completed at date of last report, has been finished, inclosed, and sodded. · INTERIOR LINE. Fort Bennett: Magazine has been re-enforced. Fort Corcoran·: One magazine has been rebuilt and the other two re-enforced; a new bomb-proof 158 feet long has been built; interior revetment repaired; embrasures new]y revetted, and seven new platforms and embrasures made. Fort Whipple: At date of last report this work was nearly completed; since that date two filling-rooms (traverses) and one bomb-proof guard-house have been built, the terre-pleins graded, and the interior of the work completely added. Fort Albany: Scarp revetment has been repaired, and some alterations in platforms and embrasures made. BATTERIES AND RIFLE-PITS.

Auxiliary to Fort Whipple four batteries-mounting respectively seven, four, ten, and four; aggregate, twenty­ five guns-have been built, and 800 yards of rifle-pit or infantry covered way has been thrown up. Across the valley of Four Mile Run, about 550 yards of heavy covered way has been thrown up, with wet ditch in front. Around and auxiliary to Fort Williams, 1,200 yards of rifle-pit or infantry covered way have been thrown up, and two batteries, mounting five guns each, have been built. Between Forts Williams and Ellsworth, two batteries, mounting respectively seven and eight guns, have been built, and JOO yards of infantry parapet thrown up. A battery mounting five guns has been built to right of Fort Lyon, together with fifty yards of rifle-pit. NEW FORTS. A new fort between Forts Strong and Woodbury, having 322 yards of crest line and mounting fifteen guns, has been nearly completed and is now nearly ready for its armament. It has one magazine, three traverses, and a bomb-proof, just commenced, 150 feet long. . A new fort between Forts Whipple and Albany, on interior line, having 539 yards of crest line and a proposed armament of thirty-three guns, has been commenced. The parapets are about half thrown up and some 100 yards of pole revetment completed. Civil War Defenses of Washington Page F-5 Historic Resources Study Part I-Appendix F

A stockade, with gateway, has been built across the Leesburg turnpike to right of Fort Marcy, and some 150 yards of abatis laid in front of rifle-pit to the Potomac River. A stockade, with gates, has also been built across approach to Aqueduct Bridge, and some seventy-five yards of rifle-pit thrown up in connection therewith. MILITARY ROADS.

The following military roads have been built during the year: Aqueduct Bridge to Fort C. F. Smith, one mile and a third; Fort C. F. Smith to Fort Strong, including branch, two-thirds of a mile; Aqueduct Bridge to Fort Whipple, one mile and a half; Camp Barnard to Fort Whipple, one mile and a quarter; Four-Mile Run to Fort Ward, two miles and a half; total, seven miles and a quarter. Two large block-houses have been commenced and nearly completed in valley of Hunting ·Creek These have been built by the quartermaster department, under the direction of the chief engineer of the defenses. CONDITION OF THE WORKS.

With a few exceptions, the forts south of the Potomac are now very complete as to their interior arrangements. Most of them are provided with good bomb-proofs, magazines, implement and filling rooms, and traverses where required. In nearly all of them the platforms and embrasures have been repaired during the past season and are now in good order. The exterior slopes on the line from Fort Smith to Fort Berry (nine forts), inclusive, have been built up on 45-degree slopes from the bottom of the ditch, and only require sodding to make them stand for many years. Three other works, Forts Albany, Richardson, and Barnard, have their scarps revetted with plank; and one other, Garesche, has its scarp revetted with stockade. Forts Ward and Williams have also exterior slopes of 45 degrees, which, when sodded, will make them permanent. Some of the older works, as Forts.Worth. Ellsworth, and Lyon, yet require extensive repairs, and Forts Strong, Cass, and Craig require new magazines. WORK PROPOSED TO BE DONE.

First. Work now in progress and which it is expected to complete this season: Fort Strong: Two new magazines to be built. Fort Ethan Allen: Bomb.proof covering to be completed, trimmed, and sodded. Fort Morton: Bomb-proof to be built and fort to be trimmed and sodded. Fort Woodbury: Bomb-proof to be completed and fort to be sodded. Fort Cass: Two new magazines to be built and fort to be sodded. Fort Craig: Two new magazines to be built. Fort Ward: Bomb-proofs to be completed, terre-plein graded, and the work to be sodded. Fort Ellsworth: Bomb-proof to be completed, terre-plein graded, and work to be sodded. Completion of two block-houses and battery in valley of Hunting Creek. Second. New works contemplated for the next" year: The new fort between Forts Whipple and Albany; this is an extensive work and will require many months to complete it. A battery for field guns to left of Chain Bridge to command Leesburg mad and valley of Pimmit Run. A battery to left of Fort Corcoran. A fort at Columbia turnpike in front of Fort Richardson. A block-house between Fort Ward and Battery Garesche, on Leesburg pike. The commission appointed by the Secretary of War also recommended two large forts to be built in front of that portion of the line from Fort Smith to Fort Craig. Third. Repairs necessary to be made: The abatis requires to be renewed along the whole line from Fort Albany to Fort Lyon, inclusive, with the exception of Forts Berry, Garesche, Ward, and Williams. New magazines will be required next season at the following forts: Albany, two; Corcoran, two; Scott, one; Richardson, one; Reynolds, one; Worth, two; Lyon, one; total, ten. New bomb-proofs will be required at Forts Albany and Worth, and probably at Forts Barnard and Reynolds. New interior revetments will be required at most of the old works not already revetted, probably at Forts Reynolds, Scott, Worth, Ellsworth, and Lyon. Civil War Defenses of Washington Page F-6 Historic Resources Study Part I-Appendix F

Re-enforcement of parapets will be required at several of the old works, viz, Ethan Allen, Marcy, Corcoran, Scott, Reynolds Worth, Ellsworth, and Lyon, and in its dependent redoubts. Revetment of scarps will be required either by sodding the whole exterior slopes at all the forts on the line not already revetted on an angle of 45 degrees by a scarp wall of brick or stone, or by a scarp revetment of plank. The repairs needed at Fort Worth are so extensive as to amount nearly to rebuilding the entire fort, as has been done at Fort Ward. Military roads are required to be built as follows: From Fort Whipple, passing to rear of Forts Tillinghast and Craig, down the ravine in front of Fort Albany, to connect with the road to Convale·scent Camp, a distance of one mile and five-sixths, whence there is now a good road to Fort Ward; thence a road from Fort Ward, passing to rear of Forts Worth and Williams, to Ellsworth, a probable distance of two miles and a half. Also a road from Fort O'Rorke to Fort Willard, and branch to Fort Farnsworth, a distance of one mile and 245 feet. In addition to the work mentioned above as in progress or contemplated to be done, there are two or three other works with reference to which no decision has been made, though the matter has been under consideration. DEFENSES NORTH OF THE POTOMAC.

These consist of 29 forts, having a total length of 13,295 yards of crest of parapet, with emplacements for 416 guns, 55 batteries, having 3,516 yards of crest of parapet, with emplacements for 262 guns, and 14,842 yards of infantry parapet or covered way. The armament of these works at present is 385 guns and 38 mortars. During the past year the force employed has been engaged as follows: Fort Foote: Completing the fort, with its counterscarp galleries. Fort Greble: Constructing two new magazines, bomb-proofs, traverses, and repairing parapet. Fort Carroll: Constructing four , new magazine implement room (house), traverses, platforms, embrasures, repairing old revetments, grading , and renewing abatis. Fort Snyder: Repairing parapet and constructing new platforms. Fort Stanton: Constructing three bastions, two new magazines, bomb-proofs, traverses, platforms, embrasures, grading glacis, and renewing abatis. Forts Ricketts, Wagner, Davis, and Du Pont: Repairing parapets and revetments, and constructing new platforms and embrasures. Fort on hill south of Fort Mahan, proposed to be called Fort Chaplin: Constructing the fort, which is a new one and nearly finished. Fort Mahan: Repairing and enlarging the rifle-pits and constructing a new battery. Battery Jameson: Repairing and improving parapet, rebuilding bomb-proofs and platforms. Forts Lincoln, Thayer, Saratoga, Bunker Hill, and Slemmer: Repairing old revetment, parapets, and sodding; completing several batteries between these works. Fort Totten: Repairing magazine, revetment, and parapet; sodding; building a part of the scarp wall with stone, and renewing abatis. Forts Slocum and Stevens: Repairing parapets, grading glacis, and renewing abatis; clearing trees and completing batteries between the forts; constructing a battery and infantry parapet to left of Rock Creek bridge, back of military road. Forts De Russy and Kearny: Repairing parapets and sodding. Forts Reno, Bayard, Simmons, and Mansfield: Repairing and sodding parapets; completing batteries and forts, and laying abatis. Fort Sumner: Repairing the parapets and magazines; constructing two traverses in Redoubt Davis. Two new batteries near canal: Constructing the batteries, one of which is finished and the other nearly done. In nearly all of the forts new platforms were constructed after the report of the board of officers ordered to revise the armament. Great quantities of bushes have been cut in front of the works, and some woods and orchards felled in the neighborhoods of Forts Stevens, Slocum, and Mahan. Civil War Defenses of Washington, Page F-7 Historic Resources Study Part I-Appendix F

These works are, generally speaking, in good condition, so far as their interior arrangements are concerned, the principal defect being the want of good strong abatis around some of the forts: They have all been provided with abatis, but some of it is over three years old, and so rotten and broken as to be almost useless as a means of defense, and so dry as to be easily set on fire. The parapets of some of the forts have been sloped and sodded, but in many others this has not been done, and the slopes are more or less washed out of shape in consequence. Each fort is provided with at least one good dry magazine, and nearly all have bomb-proofs. In some of the forts, however, bomb-proofs have never been built, but it is proposed to construct them as soon as the completion of more important works on the line will permit. The present length of the military road, with its branches, is about eighteen miles. It is in a passable condition, but needs repairs in some places. The work remaining to be done is as follows: Fort Foote: A battery on the bank of the river in rear of Fort Foote, to flank the water approach to that work, should be constructed, and a redoubt should be built on Rosier's Hill, which is the key of the position. Fort Carroll requires a new magazine and bomb-proof. Fort Stanton requires a battery and some rifle-pits to sweep the ravine in front. Anacostia Bridge requires a block-house or other protection to the head of the bridge. Fort Baker needs an additional bomb-proof; also a battery and covered way to sweep the ravine in front. Fort Baker to Fort Mahan: This line requires additional defenses not yet determined. Fort Mahan requires a bomb-proof and two new magazines. Eastern Branch: Some defenses on the west bank are required to prevent the crossing of the stream and to flank the approach to Fort Mahan. · Fort Lincoln requires a new magazine; also counterscarp galleries to flank the ditches. Forts Thayer, Saratoga, Bunker Hill, and Totten require new magazines. Fort Slocum requires a new magazine and bomb-proof in the old fort. Fort Stevens: Part of the abatis of this fort wants renewing, and a flanking battery or infantry parapet on the right of the fort would add greatly to its strength. Forts De Russy, Kearny, Reno, Bayard, Simmons, and Mansfield are all in good condition. Fort Sumner requires a new magazine in each redoubt; also a bomb-proof. Battery Martin Scott and Chain-Bridge Battery require repairs. Aqueduct Bridge: A small battery should be built to sweep this bridge. In addition to the work detailed above, the greater number of the present forts require sodding; many require new abatis, revetment of breast-heights, and scarps. The new magazines stated above as needed are to replace those first constructed, which were built of white pine boards and frame, in the quickest manner, when the earlier forts were being hastily thrown up. The boards of these buildings are now rotting out, causing leaks, which render the magazines unfit for the safe keeping of ammunition. They should be rebuilt in a more permanent manner of logs and oak boards. Some of the forts have never been provided with bomb-proofs and filling-rooms, which are very necessary. MILITARY ROADS.

No proper military road has yet been constructed to connect the works over the Eastern Branch. Such a road is a very useful and essential part of the system of the defenses. Again, that portion of the military road between Fort Stevens and Fort Lincoln was made more with a view of taking advantage of the existing roads of the country, for giving facilities in constructing the different works, than with a view of getting a military road under cover from an enemy, over which troops and artillery could move unseen and in security during an attack, and, as a consequence, the location of this road could be much improved. RECAPITULATION. Civil War Defenses of Washington Page F-8 Historic Resources Study Part I-Appendix F

The defenses of Washington consist of 60 forts, 93 batteries, and 35,711 yards of infantry covered way. There are emplacements provided for 1,447 guns. The present armament is 762 guns and 74 mortars. Notwithstanding the great number of works, and their numerous artillery, we should be careful not to allow ourselves to assume either of these as a standard by which to estimate the security they give to the city. The works are passive, and of themselves have no strength, unless they are properly manned. The line of defense is some thirty­ seven miles long, and to man such a line properly against the attack or investment of a powerful army will require a large force. In such case, the works stand for so many men, enabling a smaller force to resist a larger one. Up to this time, these defenses have done all that they have been called upon to do; have fulfilled the object for which they were built. It is our duty to see that they shall be enabled to withstand any possible attacks in the future.No one would have believed twelve months ago that within a year a large force of the enemy would encamp within sight of the Capitol, and that one of our forts would be seriously threatened. Yet it has been even so, and if that fort had not been built, or had been improperly constructed, there can be but little doubt but that the enemy would have taken possession of the seat of government. Improbable as it may appear at the present time, it is the part of prudence to remember that history repeats itself, and that we should guard against such a contingency in the future. To do this effectually, we must keep the defenses in order. These being built of perishable materials, like a railroad, require constant repairs; old magazines require to be repaired or rebuilt; new bomb-proofs are required in many of the works; decayed revetments must be renewed; worn-out gun platforms require renewal; decayed abatis must be replaced by new; the scarps require constant attention-they must all be sodded, or revetted with masonry before the works can assume a permanent character; all interior earthen slopes of traverses, magazines, bomb-proofs, camps, &c., should be sodded; besides, some additional redoubts and batteries should be built in order to render these already constructed more secure. For these objects, "To keep in repair and render more permanent the defenses of Washington," an appropriation of $500,000 for the fiscal year ending July 1,1866, will be required. Very respectfully, your obedient servant, B. S. ALEXANDER, Lieutenant-Colonel and Aide-de-Camp. ORA, I, 43, Part 2 (serial 91), 280-288.

HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, May I, 1865.

Brig. Gen. R. DELAFIELD, Chief of Engineers:

SIR: I have the honor to acknowledge the receipt of the circular of the Department of the 29th ultimo, in reference to suspending operations on field fortifications and to collecting and preserving engineer property. As I suppose the time has now arrived when the policy of the Government in reference to the fortifications of this city should be settled, I take advantage of the occasion of this acknowledgment to ask for more detailed instructions than are contained in the general circular of the Department. I have always supposed that it will be the policy of the Government, even after the termination of the rebellion, to maintain the more important works of defense around this city. It seems to me after our experience during this rebellion that a wise foresight will not permit us to allow the seat of government to become again entirely defenseless. Besides this there will probably be a considerable body of troops hereafter stationed in or around this city, at least for some years to come, and, if so, the present forts will be the best place at which to post them. At present we have seventy-four inclosed forts and armed batteries around this city, each of which requires a garrison or at least a guard to protect it. This is a war establishment, entirely too large and expensive to be maintained in time of peace. Many of these forts and batteries must be abandoned, and if it be decided to maintain some of them the question arises how many and which forts shall be so maintained? Civil War Defenses of Washington Page F-9 Historic Resources Study Part I-Appendix F

In order to a proper understanding of the subject, I will state that before the receipt of the circular of the Department, I had anticipated, to some extent at least, the orders of the Secretary of War and the instructions of the Department by suspending operations on all new works, and as far as practicable on all the old works of secondary importance, and since that time have confined operations to the more important forts standing on prominent points and commanding the approaches to the city. To be specific, so that there may be no misunderstanding, I will add that my instructions contemplated the keeping up of twenty forts, ten on each side of the river, viz: North of the Potomac, Fort Carroll, Fort Stanton, Fort Baker, Fort Mahan, Fort Lincoln, Fort Totten, Fort Slocum, Fort Stevens, Fort Reno, and Fort Sumner. South of the Potomac, Fort Lyon, Fort Ellsworth, Fort Worth, Fort Ward, Fort Richardson, Fort McPherson, Fort Whipple, Fort Morton, Fort C. F. Smith, and Fort Ethan Allen. This list, as will be seen, does not include either Fort Foote or Battery Rodgers, the two water batteries for the defense of the river approach to the city, which I took for granted would be maintained. Such was my idea of what ought to be done before I received the circular of the Department, and such is still my opinion. Congress having made '.'specific appropriations for completing and rendering more permanent the defenses of Washington," it appears to me that, as it is not desirable to keep up all the works, we will be carrying out the intention of Congress in the best possible manner by "completing and rendering more permanent" the works which I have named. In issuing the orders to which I have alluded I supposed that I had reduced the number of works to a minimum. Though there are twenty forts it may be said that there are only thirteen positions to be held by them, two of which, embracing Forts Lyon and Ellsworth, Worth, and Ward, cover Alexandria, and one, embracing Fort Ethan Allen, covers the Chain Bridge. The question presented for consideration is one of policy. Does the Government wish any of the works now constituting the defenses of Washington to be maintained? If so, is it desirable that the number of these works should be reduced to a minimum? If these questions are answered in the affirmative then all necessary orders have already been given and I shall in future confine my operations to finishing the work already commenced at the forts above designated. Holding these we command most of the approaches to the city, and have the skeleton of a line of defense which can readily be built up again on the breaking out of a future war. Very respectfully, your obedient servant,

B.S. ALEXANDER, Lieut. Col., Aide-de-Camp, and Chief Engineer of Defenses.

ENGINEER DEPARTMENT, Washington, D.C., May 6, 1865.

Hon. E. M. STANTON, Secretary of War, Washington, D. C.:

SIR: The defenses of Washington at this time consist of seventy-four inclosed forts and armed batteries, each having a guard or garrison, and armed with 905 guns of various calibers, with magazine stores with powder and fixed ammunition amounting to about 200 rounds per gun, or 181,000 rounds. This system of defensive works envelopes the city, navy-yard, Alexandria, and Georgetown, and was constructed against rebel enemies who could approach by land from north, south, east, and west, and is about thirty-two miles in extent. The necessity for this extensive system of temporary works no longer exists, and I recommend that fifty-one of these forts and inclosed batteries be at once dismantled, the artillery and stores of all kinds withdrawn, and deposited either in the remaining twenty-three forts or at the arsenals, stores, and depots under charge of the different military departments of the army. After disarming, dismantling, and withdrawing the stores, a guard should remain to protect the property Civil War Defenses of Washington Page f:-10 Historic Resources Study Part I-Appendix F

from fire and injury, and measures taken to restore the grounds to the rightful owners. To this end it is advisable, as - far as practicable, to liquidate claims on the Government for the uses and changes made to the property by conveying to the owners the right and title to the buildings and fixtures, of timber on the bomb-proofs, magazines, and stockades of the several works; which if unacceptable to the claimants in full satisfaction for the use of the ground, changes,, alterations, and removal of fences, woods, trees, and all others made by the authorities of the United States, the same shall be removed and materials in part sold in such manner as shall be found most advantageous to the public interest, and the residue stored as may be useful for the military service elsewhere. The works to be retained for the present will be: On the north of the Potomac: Fort Carroll, Fort Stanton, Fort Baker, Fort Mahan, Fort Lincoln, Fort Totten, Fort Slocum, Fort Stevens, Fort Reno, and Fort Sumner; and on the south of the Potomac: Fort Lyon and three redoubts, Fort Ellsworth, Fort Worth, Fort Ward, Fort Richardson, Fort McPherson, Fort Whipple, Fort Morton, Fort C. F. Smith, and Fort Ethan Allen. The two river forts, to wit, Fort Foote and Battery Rodgers, will also be retained for the present. These twenty-three retained forts and redoubts occupy and command thirteen positions or lines of approach by roads or cover the cities of Alexandria, Georgetown, and Washington; its navy-yard and arsenal, and the roads from the north, west, south, and east, At a later period, after the fifty-one works and all their connecting lines of intrenchments have been vacated and ground restored to the owners, some of the remaining twenty-three may probably be dismantled and the grounds in like manner restored to their proprietors. The preceding recommendation is founded upon the consideration that a large garrison is necessary for some time to come, and in part to be permanently stationed in and about this city for the protection of the national executive authorities, its archives, its costly and extensive public buildings, vieing with any of those in Europe for magnificence, elegance of architecture, durability, and fitness for the intended purposes; and its naval establishment and extensive ordnance depots, the value and cost of which is millions of dollars, and the destruction of which would be a serious loss and prejudice to the public welfare. Not less than 10,000 men at the "present time, it is believed, will be necessary under all considerations to be retained in and about the city, and the twenty-three retained forts are selected with the view of best protecting the public interests and providing quarters and other accommodations for such a garrison. It is also considered, in connection with holding these defenses and maintaining this garrison in and about Washington, that for the maintenance of law and order and the protection of the rights of the many millions of colored people in the late slave States, garrisons will have to be established for some time near Richmond, Raleigh, Columbia, Charleston, Macon, Atlanta, Nashville, and other points not now necessary to particularize, in sufficient force to quell instantly any violation of law or threatened disturbance of the public peace, by strong detachments ordered from these central garrisoned depots. Their selection should be in the most populous districts of colored inhabitants and on lines and routes of railroad and river (steam) communication.· Twenty such garrisoned depots, of 5,000 men each, would insure and secure respect for and enforcement of the laws of the land and protection of the rights of individuals, while the could effectually garrison our entire seaboard defenses on the Atlantic, Gulf, , and lake coasts, thus calling for about 125,000 of the existing national forces to be selected and retained for a time from the existing heroic armies that have enforced law against traitors and saved the Union of the States as one and indivisible. With time and established acquiescence in the new order and economy of labor, this force of 125,000 men could be allowed gradually, by deaths and expiration of term of service, to fall to the strength that the wants of the nation might demand. The next great care of the nation should be the creation of a well-organized and efficient staff for every branch of the military service, which, with well-trained and instructed officers of the three arms, would insure the nation's vit~lity against internal discord and foreign insult or aggression. With such a disposition of the army it will be readily perceived that much of the material of construction now belonging to the United States and in existing temporary buildings can be made advantageously available, rather than selling them at a sacrifice. The cemeteries and one of the best permanent hospitals, as the Surgeon-General can best select, should constitute a part of the military establishment to be preserved. Respectfully, your obedient servant, Civil War Defenses of Washington Page F-11 Historic Resources Study Part I-Appendix F

HDQRS. DEPARTMENT NORTHEASTERN VIRGINIA, \ Arlington, May 29, 1861. Lieut. Col. E. D. TOWNSEND, Asst. Adjt. Gen., Hdqrs. of the Army, Washington, D. C.:

COLONEL: I arrived here too late in the afternoon of the 27th to assume on that day formally, in orders, the command of the department, but I reported to Major-General Sandford at this place and received from him such information as to the state of affairs as he was able then to give me. I encamped the night of the 27th with the New Jersey brigade, and early on the morning of the 28th went to Alexandria and was occupied from 5 a.m. till 9 o'clock at night in examining the position occupied by the troops and looking into the condition of the men. Defensive works under construction.-The works at Alexandria had not been commenced nor even laid out as late as 10 o'clock a.m. yesterday, nor had the plans been definitely determined upon. A want of tools in the fi_rst place, and in the second place of means of transportation for the men-from the wharf in Alexandria to the hill to be fortified, and changes made necessary by a better knowledge of the ground, were the principal causes given for the delay. Both the Michigan regiment and the New York were bivouacked and encamped on the site, leaving but a few men in town. I trust, therefore, that the Navy Department may be requested to {retain] the Pawnee at her present station. The works at the bridge-head of the Long Bridge were progressing finely, and the report to me was that the men were working diligently. The main work covering the Aqueduct and ferry opposite Georgetown was in a fair state. The Sixty-ninth New York is the only regiment at work on it, and they seemed to me to be working admirably. Subsistence and means of transportation.-Subsistence is furnished to the troops away from the vicinity of Alexandria by returns on the main depot in Washington. This, and the utter absence of any wagons on this side, the warit of means of communication on the part of some of the regiments, and the inexperience of most of the commanders, have caused the supplies to be irregularly and insufficiently furnished. One regiment has hired on its own account, out of private means, some wagons to procure its supplies. Forage has also been wanting. A depot is to be established at Alexandria, which will afford supplies to the troops in that vicinity. The depot in Washington might answer for all the others, provided the regiments be furnished with wagons to go for them. I suppose the Quartermaster's Department in Washington has not at this time enough wagons to supply the force here with its allowance for its baggage merely, which would require about 200. For the purpose of giving greater efficiency and a better administration of affairs, I have organized the troops not now brigaded into three brigades, and placed them under the colonels ordered to report to me in their letters of appointment. Civil War Defenses of Washington Page G-2 Historic Resources Study Part I-Appendix G

If a portion of the allowance of wagons for the regimental baggage were sent on and placed under the control of the brigade commanders, I think a better state of affairs will be gained at the least cost. With a view to movements in that , direction, I have directed Colonel Stone to ascertain and report the amount of rolling stock on the Alexandria and Manassas Gap Railroad, and the amount of material required to place the road in working order. I beg to request that some of the recent graduates heretofore assigned to the duty of instructing the volunteer regiments may be sent here for the same purpose and other duty. The only assistant quartermaster in the department is at Alexandria, to be in charge of the Quartermaster's and Commissary Departments. I have"to request that another officer of that department, furnished with funds, be sent for duty at headquarters. The troops are occupying houses in some cases, and fields, and cutting wood for fuel. Shall not rent and compensation be paid? If so, funds are needed for that purpose, as well as the hiring of means of transportation where the same has not been furnished. I have the honor to be, colonel, very respectfully, your most obedient servant,

IRVIN McDOWELL, Brigadier-General, Commanding.

Statements of the amount, kind, and value of all private property taken and used for Government purposes, and of the damage done in any way to private property by reason of the occupation of this section of the country by the U.S. troops, will, as soon as practicable, be made out and transmitted to department headquarters by the commanders of brigades and officers in charge of the several •fortifications.

These statements will exhibit-

I st. The quantity of land taken possession of for the several field-works, and the kind and value of the crop growing thereon, if any. 2d. The quantity of land used for the several encampments and the kind and value of the growing crop thereon, if any. 3d. The number, size and_character of the buildings appropriated to public purposes. 4th. The quantity and value of trees cut down. 5th. The kind and extent of fencing, &c., destroyed.

These statements will, as far as possible, give the value of the property taken or of the damage sustained, and the name or names of the owners thereof. Citizens who have sustained any lessor damage as above will make their claims Civil War Defenses of Washington . Page G-3 Historic Resources Study Part I-Appendix G

upon the commanding officers of the troops by whom it was done, or in cases where these troops have moved away, upon the commander nearest them. These claims will accompany the statements above called for.

The commanders of brigades will ·require the assistance of the commanders of regiments or detached companies, and will make this order known to the inhabitants in their vicinity, to the end that all loss or damage may, as nearly as possible, be ascertained, whilst the troops are now here, and by whom or on whose account it has been occasioned, that justice may be done alike to the citizen and the Government.

The name of the officer or officers (in case the brigade commanders shall institute a board) who fix the amount of loss or damage shall be given in each case.

GENERAL ORDERS, No. 18

HDQRS. DEP'T NORTHEASTERN VIRGINIA,

Fairfax Court-House, July 18, 1861.

It is with the deepest mortification the general commanding finds it necessary to reiterate his orders for the preservation of the property of the inhabitants of the district occupied by the troops under his command. Hardly had we arrived at this place when, to the horror of every right-minded person, several houses were broken open and others were in flames by the act of some of those who, it has been the boast of the loyal, came here to protect the oppressed and free the country from the domination of a hated party. The property of this people is at the mercy of troops who we rightfully say are the most intelligent, best-educated, and most law-abiding of any that were ever under arms. But do not, therefore, the acts of yesterday cast the deeper stain upon them? It has been claimed by some that their particular corps were not engaged in these acts. This is of but little moment; since the individuals are not found out, we are all alike disgraced. Commanders of regiments will select a commissioned officer as regimental provost-marshal, and ten men as a permanent police force under him, whose special and sole duty it shall be to preserve the property from depredation, and arrest all wrong-doers, of whatever regiment or corps they may be. Any one found committing the slightest depredations, killing pigs or poultry, or trespassing on the property of the inhabitants, will be reported to headquarters, and the least that will be done to them will be to send them to the Alexandria jail. It is again ordered that no one shall arrest or attempt to arrest any citizen not in arms at this time, or search or attempt to search any house, or even to enter the same, without permission. Civil War Defenses of Washington Page G-4 Historic Resources Study Part I-Appendix G

The troops must behave themselves with as much forbearance and propriety as if they were at their own homes. They are here to fight the enemies ·or the country, not to judge and punish the unarmed and helpless, however guilty they may be. When necessary, that will be done by the proper persons.

By command of Brigadier-General McDowell:

The military governor of Alexandria will immediately organize a camp of convalescents, stragglers, and recruits, under the following regulations: · II. All officers absent from their regiments without a proper pass, approved by their division commander, will, if their regiments are stationed in or near Washington, be ordered to join them, in arrest, and the fact will be duly reported to division commanders by the provost-marshal. (See Paragraph III, of General Orders, No. 2, from these headquarters.) III. Every officer absent from his regiment without a proper pass, and whose regiment is not near Washington, will be ordered by the officers of the provost guard to report in person to the provost-marshal, who will direct him, in writing, either to proceed to join his regiment within twenty-four hours, or within the same period to proceed to Alexandria, and report to the military governor of that place for duty at the convalescent camp. Such an order is sufficient authority to pass the_guards at the bridge or ferry to Alexandria. IV. All enlisted men arrested for being absent without a proper pass will, if their regiments are near Washington, be proceeded with as directed by General Orders, No. 2, from these headquarters. If their regiments are not near Washington, they will be sent, in squads, once each day, under guard, to the-military governor of Alexandria, who will place them in the convalescent camp. V. The military governor of Alexandria will enforce the same regulations so far as regards that city. VI. The military governor of the District of Columbia will cause daily lists of the officers so ordered to report to be furnished to the military governor of Alexandria. The military governor of Alexandria will cause a complete register to be kept of all officers ordered to report at, and a separate register of all enlisted men sent to, the convalescent camp·, and will communicate daily to the military governor of the District of Columbia the names of all officers who should have reported to him within the past twenty-four hours but who have failed so to report, and he will transmit weekly to each division commander a transcript of the register for the past week, so far as relates to his division. VII. All recruits arriving for regiments which are not near Washington will be sent to the convalescent camp. VIII. As far as practicable, the convalescents, stragglers, and recruits will be organized in squads, according to divisions or corps, each sq~ad in charge of an officer from the division or corps.

GENERAL ORDERS No.42. WAR DEPT.,ADJT. GENERAL'S OFFICE, Washington, February 2, 1864. The following regulations for the care of field-works and the government of their garrisons, prepared by Brigadier­ General Barry, ins·pector of.artillery, U.S. Army, are published for the government of all concerned: 1. It is the duty of the commanding officer of each work' to provide for the care of the armament and the safety and serviceable condition of the magazines, ammunition, implements, and equipments; and by frequent personal inspections to secure the observance of the rules prescribed for this purpose. 2. The fixed armament, consisting of the heavy guns and thos·e the positions of which are prescribed, will be numbered in a regular series, commencing with the first gun on the right of the entrance of the main gate. Where there are platforms temporarily unoccupied by guns they will be numbered in the regular series. The ammunition will be kept in the magazines, with the exception of a few stand of grape, canister, and solid shot, which will be piled near the guns. 3. The gun carriages will be kept clean and all axles and journals well lubricated. They will be traversed daily, and never be allowed to rest for two successive days on the same part of the traverse circle. If the gun carriage does not move easily on the chassis the tongue will be occasionally greased. The upper carriage should not rest habitually on the same part of the chassis. 4. The elevating screw and its box will be kept clean and well greased. When the guns are not in use the screw will be run down as far as it will go, the breech of the piece being first raised until the muzzle is sufficiently depressed to prevent water running into it, and kept in that position by a wooden quoin or block. The tompion should be kept in the muzzle and the apron over the vent. 5. The piece is not to be kept habitually loaded. It will be time to load when the enemy appears, or when special orders to that effect are given. · _6. The commanding officer will see that a shed is constructed for the implements and equipments. For each drill these will be issued to the gunners by the ordnance sergeant, or other non-commissioned officer acting_ as such, who will receive and put them away after the drill is over, and be at all times responsible to the commanding officer for their safety and serviceable condition, and that the supply is adequate. When sheds cannot be provided, the implements will be kept near the pieces or in the bombproofs. The equipments (haversacks, tube pouch, &c.) may be kept at the entrance of the magazine, where they will be sheltered. Platforms for projectiles will be laid near the guns; for canisters, a couple of pieces of scantling for skids will answer. A watershed, made by joining two beards together at the edges, should be placed over them. When the wooden sabots become wet they swell and burst the canisters, so that they cannot be put into the gun. When this happens dry the sabot until it shrinks sufficiently for the canister edges to be brought together and tacked. 7. When not supplied by the Engineer Department materials for constructing the sheds and for skidding will be· furnished by the Quartermaster's Department, on requisitions made to the Chief of Artillery. 8. The magazines must be frequently aired in dry weather. For this purpose the ventilators and doors must be opened after 9 a.m., and must be closed at latest two hours before sunset. The ammunition for different classes of guns will be carefully assorted, and the shelves, boxes, or barrels containing each kind plainly marked. When there is inore than one magazine the ammunition will be so distributed as to be near to the particular guns for which it is provided. Cartridges must be moved, and, if necessary, rolled once a week to prevent caking of the powder. In doing this care must be taken not to pulverize the grains. Friction-primers must be kept in the tin packing boxes and carefully protected from moisture. They will be frequently examined and dried by exposure to the sun. This must always be done immediately after wet _·civil War Defenses of Washington Page G-16 Historic Resources Study Part I-Appendix G

weather of long continuance. The supply of friction-primers for each gun must be 50 per cent. greater than the number of rounds of ammunition provided for it. A dozen primers will always ·be kept in the tube pouches in use at each gun. Three lanyards will be provided for each gun, one of which will be kept in store, the other two in the tube pouches. As soon as received the hooks will be tested to see if they are sufficiently small to enter the eye of the primer, and yet strong enough for use. · 9. In order that practice may be had in the use of friction-primers, authority is given to expend on drill five per gun each month. These primers will always be taken from those longest at the post. 10. There should be one lantern for every three or four guns, and two good globe lanterns for each magazine. 11. No person will be allowed to enter the magazine except on duty, and then every precaution against accidents will be taken. Lights must always be in glass lanterns, and carried only by the person in charge of the magazine. Swords, pistols, canes, spurs, &c., will not be admitted, no matter what may be the rank of the person carrying them. Socks or moccasins will be worn, if they can be procured; if they cannot, then all persons must enter with stocking-feet. No fire or smoking will be allowed in the vicinity when the doors or ventilators are open. Too many precautions cannot possibly be taken to avoid the chances of an explosion. A copy of this paragraph, legibly written, will be conspicuously posted near or on the door of every magazine. 12. Companies will be assigned to guns in such proportions as will furnish at least two, preferably three, reliefs in working them, and sufficient men in addition for supplying ammunition from the magazines. From fifteen to twenty men should therefore be assigned to each gun and instructed in its use. Companies should habitually serve the same guns, each man being assigned a special number at the gun, andthoroughly instructed in all its duties. As occasion offers, all of the officers and enlisted men should be instructed at each of the different kinds of gun at the post, as well as in the duties of all the numbers at each gun. Every night at retreat or tattoo the men who are to man the guns in case of a night attack should be paraded at their pieces and inspected, to see that all their equipments, implements, and ammunition are in good order, and the guns in serviceable condition and easy working order. The men so stationed should "call off' their numbers before being dismissed. In case of alarm at night all should repair at once to their posts, equip themselves, and await orders, without losing time by forming upon their company or battalion parade grounds. 13. Each gun should be under charge of a non-commissioned officer, and to every two or three guns should be assigned a lieutenant, who will be responsible to the captain for their serviceable condition at all times. The captain will be responsible to the commanding officer for the condition of the pieces and the instruction of the men of his company. Artillery drills will be frequent until all of the men are well instructed, and there will never be less than one artille·ry drill per day when the weather will permit, nor will any officer be excused from these drills unless it is unavoidable. For action, all the cannoneers not actually serving the guns will be provided with muskets, and will be stationed near the guns to which they belong, for service on the banquettes or elsewhere, in case of assaults. 14. Each company should be supplied with three copies of the Tactics for Heavy Artillery, and rigidly adhere to its directions. Tables of ranges will be found in the work. One copy of Instructions for Field Artillery should be supplied to each company. All authorized books can be obtained on written application to the chief of artillery, who will obtain them from the Adjutant-General of the Army. The books so drawn are the property of the United States for. the use of the company, and will be accounted for on the muster-rolls. 15. The commanding officer will make himself conversant with the approaches to his work, the distance to each prominent point commanded by his guns, the nature of the ground between them and his post, and the most probable points of attack upon it. He will. also make it his duty to see that all of his officers, and, as far as possible, his non­ commissioned officers, are thoroughly acquainted with these matters. The distances will be ascertained by ,actual measurement and not left to conjecture. Tables of ranges or distances for each point, and the corresponding elevation, according to the nature of the projectile, with the proper length or time of the fuse, when shell or case-shot are used, will be made out for each gun and furnished to the officer and non-commissioned officers serving it. These tables should be painted upon boards and securely fastened in a conspicuous place near the gun. As these tables differ for different kinds of gun, the same men should be permanently assigned to the same piece. 16. The projectiles should be used in their proper order. At a distance, solid shot; then, shells or case-shot, especially if firing at troops in line; canister or grape is for use only at short ranges. When columns are approaching so that they can be taken in direction of their length, or very obliquely, solid shot is generally the best projectile, because of its Civil War Defenses of Washington Page G-17 · Historic Resources Study Part I-Appendix G

greater accuracy and penetrating power. If the column consists of cavalry, some shells or case-shot will be useful, from the disorder their bursting produces among the horses; but shells and case-shot should not be used against any troops when moving rapidly. The absolute distances at which-the projectiles can be used with effect vary with the description and caliber of the gun, and can be ascertained only by consulting the tables of ranges. The prominent points on the approaches to the works should be designated, their distances noted, and directions drawn up for the different kinds of ammunition to be used at each gun for these different points. During the drills the attention of the.chief of pieces and gunners should be frequently drawn to this subject. 1.7. Commanding officers will pay special attention to the police and preservation of the works. All filth will be promptly removed and the drainage particularly atte~ded to. No one should be allowed to walk on the parapets, or move or sit upon the gabions, barrels, or sand-bags that may be placed upon them. When injuries occur to the earth-works ·they should be repaired as quickly as possible by the garrison of the work. If of a serious nature, they should be.at once reported to the engineer officer in charge of the work. All injuries to the magazines or platforms of the guns will be promptly reported as soon as observed: The abatis, being a most important portion of the work, must be always well looked to and kept in perfect order. 18. Special written or printed instructions as to the supply of ammunition at the different posts, and the proportion for the different classes of guns, will be furnished by the chief of artillery to the commanders of posts. Instructions will also be furnished as to the special objects of each work, on proper application for this purpose to the chief engineer or chief of artillery. 19. No person not officially connected with the garrisons of the field-works will be allowed to enter them, except such as visit them on duty, or who have passes signed by competent authority; nor will any person except commissioned officers, or those whose duty requires them to do so, be allowed to enter the magazines, or touch the guns, their implements, or equipments. 20. The garrison can greatly improve the work by sodding the slopes of the parapet, and those of the ramps and banquettes, or by sowing grass seed on the superior slope, first covering it with surface soil. The grass-covered or sodded portions of the parapets, traverses, magazines, &c., should be occasionally watered in dry weather and the grass be kept closely cut. Early in the spring and late in the autumn they should be covered with manure. 21. As a great deal of powder is wasted in unnecessary , attention is called to paragraph 268 of Army Regulations, edition of 1861-1863: 268. A will be saluted but once in a year at each post, and only when notice of his intention to visit the post has been given. 22. The practice of building fires on the open parades, for cooking and other purposes, is prohibited, as it endangers the magazines. 23. The armament of a fort having been once established, will not be changed except by authority of the commander of the district, geographical department, or army corps, and then only on consultation with the chiefs of engineers and artillery. 24. The machinery of the Whitworth, or other breech-loading guns, will not be used except by special orders from the commanding officer of the post. 25. Experience having conclusively shown that rifled guns, of large caliber especially, rriust be subjected to most careful treatment and skillful management in order to secure their maximum efficiency, both in range and penetration, and especially their maximum endurance, the attention of all officers using rifled guns of large calibers is called to the following rules: Sponges well saturated with oil shall alone be used; and for this purpose the necessary supply of oil shall tie provided for all batteries of position in which rifled guns form the part or whole of its armament. A little grease or slush upon the base of the projectile adds much to its certainty, and should be always used when possible. The bores of the guns should be washed, and the grooves cleaned of all residuum and dirt subsequent to the firing, after the gun has cooled. Great care must be taken to send the projectile home in loading, that no space may be left between the projectile and the cartridge. Before using shells, unless already loaded and fused, they must be carefully inspected both on their exterior and interior, and scrapers should be used to clear the cavity of all molding sand before charging the shell. Special Civil War Defenses of Washington Page G-18 Historic Resources Study Part I-Appendix G

attention should be given to the insertion of the fuses, and the threads of the fuse-hole should be carefully cleaned before screwing in the fuse. In all Parrott projectiles it should be carefully observed that the brass ring or cup is properly wedged, and that, in the case of the ring, the cavities between it and the projectile are not clogged with dirt or sand. In leading shells care will be taken to fill them entirely with powder, leaving no vacant space after the fuse is screwed in. For the I 0, 20, and 30 pounder Parrott guns powder of too large a grain should not be used. The best powder for the projecting charge of these guns is what is called ''.mortar powder." 26. Pole-straps and pole-pads of field limbers, not belonging to horse batteries, are to be kept in the implement room or in the trays of the limber chest. They should be occasionally washed and oiled, as prescribed for the care of harness in Field Artillery Tactics. 27. The forts will be inspected daily by their commanding officers; and by the brigade, division, district, or department commanders, and by the chief of artillery, as frequently as possible. Particular attention will be paid at all inspections to the drill and discipline of the garrison and police of the work; to the condition of the armament, ammunition, and magazines, and as to whether the proper supply of ammunition, implements, &c., is on hand at the post. INSfRUCTIONSFORFIRING. I. The firing in action should be deliberate-never more than will admit of accurate pointing. A few shots effectively thrown is better than a large number badly directed. The object in killing is to inspire terror so as to deter or drive off the enemy, and precision of fire and consequent certainty of execution is infinitely more important in effecting this than a great noise, rapid firing, and less proportional execution. 2. To secure accuracy of fire the ground in the neighborhood must be well examined, and the distance to the different prominent points within the fields covered. by each gun measured and noted. The gunners and cannoneers should be informed of these distances, and in the drills the guns should be accurately pointed at the objects noted in succession, the gunner designatirig it, calling the distance in yards, and the corresponding elevation in minutes and degrees, until all the distances and corresponding elevation are familiar to the men. «5 RR­ SERIES ID, VOLIV» When hollow projectiles are used the time of flight corresponding to the distance must be given to the man who goes for the projectile. He tells the ordnance sergeant, or the man who furnishes the ammunition, and the latter cuts the fuse to bum the required time. 3. The gunner is responsible for the aiming. He must therefore know the distance to each prominent object in the field covered by his gun, the elevation required to reach that point, and the time of flight of the shell or case-shot corresponding to each distance or elevation. He must have a table of these ranges, taken from the Heavy Artillery Tactics, pages 236 to 247 (edition of 1862). (a) 4. These tables will be promptly prepared under the direction of the commanding officer, and copies furnished for each gun and used habitually in the drills. They will be examined and verified by the chief of artillery. 5. The attention of all officers in charge of artillery in the works is directed to the articles in the Tactics on "Pointing guns and howitzers," "Night firing," &c., pages 76 to 90. 6. Commanding officers of the works will keep themselves accurately informed of the amount and kinds of ammunition in the magazines. The supply must always be kept up to the amount prescribed by the chief of artillery or other competent authority. When it is less than that amount a special report of the fact will be made to the chief of artillery, with requisitions for the ammunition necessary to complete the supply. Commanding officers will also see that the necessary equipments are always on- hand for the service of all the guns, as prescribed in the tactics or in general orders. 7. Hand grenades are intended to be used against the enemy when he has reached such parts of the defenses (the bottom of the ditch, for example) as are not covered by the guns or by the muskets of the infantry posted on the banquettes. 8. After the enemy has passed the abatis and jumped·into the ditch hand grenades will be used; and then if he mounts the parapet he must be met there with muskets. A resolute defense against a~sault must also be made by posting men with muskets so as to fire over the tops of traverses, bombproofs, or magazines. Civil War Defenses of Washington Page G-19 Historic Resources Study Part I-Appendix G

(a) NOTE.-(The last table on page 240 should read 8-inch sea-coast howitzer on barbette carriage, instead of 8-inch sea- coast mortar.) . For example: The cartridges for the 24-pounder guns all weigh six pounds, as issued in the Defenses of Washington. The · table (p. 236) therefore applies as follows: Twenty-four-pounder gun·on siege or barbette carriage.

Cartridge. Ball. Elevation. Range. lhs. Yards. 6 Shot 0 0 412 That is, the bore (not line of sight) being level, a range of 400 yards. 6 do I 0 842 1 degree elevation, range about 850 yards. 6 do 1 30 953 I _ degrees elevation, range about 950 yards. 6 do 2 0 1,147 2 degrees elevation, range about 1,150 yards. 6 do 3 0 1,417 3 degrees elevation, range about 1,400 yards. 6 do 4 0 1,666 4 degrees elevation, range about 1,660 yards. 6 do 5 0 1,901 5 degrees elevation, range about 1,900 yards.

Thus, supposing the enemy at a point I ;000 yards distant, by looking at the table it will be observed that 950 yards require I O 30' elevation; 1,150 yards-require 2°; therefore, elevate a very little-5' to 1O' over I O 30', or simply give 1° 30' full.

Lieutenant-General GRANT, City Point, Va.:

General Barnard is ordered to report to you. Engineer officers have been sent several times to Baltimore to lay out the works. Some are there now. I think, from personal examination, that they are better located than the defenses of Washington. It appears that Early sent a small force south with his plunder, and massed the rest near Winchester. General Averell had a skirmish there yesterday, and reports having killed and wounded over 300 rebels, taking 200 prisoners and 4 pieces of artillery. Nothing heard from Wright for three days. When he received your orders he replied that he would return as soon as assured of rebel retreat. Your telegram about merging departments is in the hands of the Secretary of War. I have no good reason for removing or superseding General Augur. He is capable and efficient. General Franklin would not give satisfaction. The President ordered him to be tried for negligence and disobedience of orders when here before, but General McClellan assumed the responsibility of his repeated delays in obeying orders. H. W.HALLECK, Major:General and Chief of Staff.

HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, July 6, 1864. Maj. Gen. H. W. HALLECK, Chief of Staff:

SIR: In compliance with your instructions of yesterday I proceeded last evening to make an examination of Chain Bridge and Aqueduct Bridge, and this morning I sent Mr. Childs, our civil assistant in charge of the works south of the Potomac, to make an examination of the Long Bridge, and I now have the honor to submit the following report on the defenses and guards of the three bridges across the Potomac, viz: Chain Bridge.-The defense of this bridge on the Virginia side consists, as you are aware, of a large tete-de-pont, comprising Forts Marcy and Ethan Allen, with a connecting line of intrenchments which extend also from the right of Fort Marcy and left of Fort Ethan Allen to the bank of the river above and below the bridge. Across the Leesburg pike, immediately on the right of Fort Marcy, there is a strong stockade with gates. This is a partial security against a sudden dash of cavalry in force, but is not a complete one, as there are paths, and, in fact, another road, passing to the left of Fort Ethan Alien leading to the bridge. The immediate defense of the bridge consists in a loop-holed gate which stands on the last pier next the Virginia shore, the whole river, except during floods, flowing between this pier and the adjacent abutment, the planks over a portion of tills span being laid down loosely so that they can be taken up at night. At this end of the bridge there is a battery armed with two mountain howitzers, intended to enfilade it, and on the hill immediately above and in rear is Battery Martin Scott, armed with two rifled 6-pounder guns. I found Lieutenant Grunwell, of the Twenty-second Regiment Veteran Reserves, with sixty-three men, in charge of the bridge. He has no command of the batteries at the east end of the bridge. These are in charge of Private Spink, One hundred and forty-seventh Ohio National Guard, acting ordnance sergeant. He knows nothing about ordnance or artillery. In fact, no one at the bridge knows how to load the guns. The business of Sergeant Spink is to clean the guns, air the ammunition, and sweep the platforms. In these duties he is assisted by a detail of six men from the One hundred and forty-seventh Ohio National Guard, changed daily. Lieutenant Grunwell closes the gates at the west end of the bridge and takes up eight or ten flooring planks in front of the gates every night at 9 o'clock. If the enemy were to attack him suddenly he "would take up the planks and make a parapet or barricade of them, and close the gates" He understands that there is a magazine in one of the western piers, arranged for blowing up the bridge, and a small lead pipe reading to the magazint::, and steps from the floor of the bridge leading down to where the pipe projects Civil War Defenses of Washington page H-2 Historic Resources Study Part I-Appendix H

from the pier. In all of which he must be mistaken as I have never heard that the piers of the bridge are mined. I remark: First. That the defenses of this bridge are sufficient, but the guard is not. The charge of the bridge with the two batteries at this end should be under one head. One man should be responsible for everything. He ought to have an ordnance sergeant and sufficient artillerists to man the four guns. Second. Precautions should be taken against fire. Two or three men could bum this bridge any night and without danger to themselves. Once on the fiats under the bridge they could lodge fire balls on the piers and under the flooring by means of poles. The guard would not know it until the bridge was on fire, and then, as things now are, they would have no means of extinguishing the flames. Hogsheads or barrels filled with water ought to be placed at intervals on the bridge with ropes, buckets, axes, &c. Third. A couple of rope ladders down the side of the pier under the gate would enable the guard at this point to escape if too strongly attacked so that the batteries could instantly open without danger to our own men. Fourth. Some twenty-five or thirty feet of the bridge flooring ought to be taken up every night. In case danger is apprehended the flooring of the sidewalks ought also to be taken up. Aqueduct Bridge.-Beside the tete-de-pont of Forts Corcoran and Haggerty, there are three block-houses near the south end of this bridge, but the latter are not occupied. The immediate defense of this bridge consists of a stockade with gates across the approach to the bridge at the south mVirginia end. Captain Blanchard, of the Veteran Reserves; commands the bridge. Has one officer and thirty men at the south end, and two officers and twenty-five men at the north end. He has no means of putting out fire, no means of patrolling the river to prevent an enemy from floating down and firing the bridge from the under side. Has applied for boats · and thinks he ought to have at least two. If a sudden attack was apprehended would close the gates and man the stockade. Did not know whether the bars for securing the gates were on hand or not; did not know whether the bars, if on hand, would fit the staples. Had never tried them. Upon examination, at my request, these were found to be in perfect readiness. No arrangements have been made for taking up the flooring of this bridge as it would involve cutting away the bottom sheathing of the aqueduct. This can be done at some little expense with time to do it, but could not be done promptly in a sudden emergency without previous preparation. I remark: First. That the guard ought to be increased so as to afford a patrol both on and under this bridge, and the same remark applies to both the other bridges. The guard should be supplied with one or two boats. Second. Precautions should be taken to guard against fire. Hogsheads or barrels of water should be kept on the bridge, and perhaps an engine kept on hand and in readiness for this purpose. Third. Additional security could be given to this bridge by putting up a battery for a section of artillery on the bank at this end of the bridge. Civil War Defenses of Washington · pageH-3 Historic Resources Study Part 1:Appendix H

Fourth. The three block-houses at the south end could be better disposed by removing them nearer to the end of the bridge. They would then afford the necessary quarters for the guard, and the guard be in the right place at the end of the bridge, whereas now it is on the bridge. Long Bridge.-Mr. Childs reports as follows: Captain Sims, of the Veteran Reserves, commands the guard at the north end of this bridge. He has sixty-four men. To guard against fire, barrels of water and buckets are placed on the bridge at intervals of thirty or forty yards. There is also a water- at the Washington end of the bridge, but is apparently not filled. The water barrels and buckets are under the charge of the railroad men or bridge tenders. Captain Sims has no boats. He thinks he ought to have them to guard against firing the bridge from the under side. The defense of the bridge is very imperfect, owing to the dilapidation and decay of Fort Jackson. The railroad cuts through the parapet and there are no gates except at turnpike entrance. The railroad crosses the ditch of the fort on a bridge which is not floored, but an enemy could soon cover it so as to make it passable. Cavalry coul~ also ride around to the lower side of the fort and come in on the bridge. I remark: First. That I do not think the guard is sufficient. I think ·there should be two companies at this bridge. Second. That although Fort Jackson may want some repairs, I am of opinion, even as it is, that fifty determined men in it could stop any cavalry raid. Third. A section of artillery with artillerists at this end of the bridge would afford all the additional security that we require. Respectfully submitted. B. S. ALEXANDER, Lieutenant-Colonel, Aide-de-Camp.

WASHINGTON, July 9, 1864. Maj. Gen. H. W. HALLECK:

GENERAL: In view of any conceivable probability of an attack on Washington, I feel it my duty to say th;it the most important re-enforcement we could have, and one to be obtained at least expense in proportion to its importance to the Army of the Potomac, would be the heavy artillery regiments formerly serving here. The First and Second Connecticut Regiments are serving as artillery regiments with that army and should not be disturbed, but the others, or most of them, are very much reduced in numbers, and through loss of field officers and numerical weakness very much injured in efficiency as infantry regiments. They are at best worth only so much infantry to General Grant. To the defenses of Washington they would be of value not to be estimated. The militia regiments now garrisoning the forts scarcely know Civil War Defenses of Washington page H-4 Historic Resources Study Part I~Appendix H

how to load or fire the guns. These artillery regiments are experienced and skillful gunners; know the guns and know the localities. The remnant of these regiments would furnish a full · · complement of experienced gunnei:s to all the forts, and impart confidence to the militia troops now in the forts, and give to the defen,se a reliability which it cannot have, do what we may without them. J. G. BARNARD, Bvt. Maj. Gen., Chief Engineer; Defenses of Washington. P. S.-I am aware that one regiment, the New York Ninth, has been ordered back, but would wish that the other and far better regiments should likewise come so as to have in each fort gunners and officers familiar with the localities.

HEADQUARTERS U.S. FORCES, Fort Stevens, July 12, 1864. SIR: Agreeably to your verbal order communicated to me last night, I have the honor to submit the following observations with regard to the status of the forces within the command of Major-General McCook: Headquarters are located in rear of Fort Stevens. From the right of Stevens to Fort Totten, inclusive, the line is held by forces under command of Major-General McCook, as follows:

Provisional Brigade. Colonel Price (approximately) 2,800 Second District, Colonel Alexander (approximately) 550 12th Veteran Reserve, Colonel Farnsworth (approximately) 550 Quartermasteremployes (approximately) 1,800 Detachment of 7th Michigan Cavalry, Major Darling, operating between Fort Stevens and Bladensburg, only portion under General McCook's command 450 Total 6,150

From Fort Stevens' left to Fort De Russy troops of Major-General Wright and Major­ General McCook are intermixed, those reporting to Major-General McCook, as follows:

2d Vermont Volunteers (approximately) 232 3d Vermont Volunteers (approximately) 272 147th Ohio Volunteers (100-days men) 465 9th U.S. Veteran Reserve Corps 350 157th Ohio 184 . Total 1,503

Amount brought forward 6,150 Total 7,653 Civil War Defenses of Washington page H-9 Historic Resources Study Part I-Appendix H

Between Forts Stevens and Slocum there is a section (2 guns) 1st Ohio Battery [L, 1st Ohio] · 121 Between Forts Stevens and De Russy, section (2 guns) 1st Maine Battery 112 233 Grand total under General McCook 7,886 No other artillery aside from guns in the forts. An order has just been issued placing-Brigadier-General Meigs in command of the line from Stevens to Totten, inclusive, Brigadier-Generals Rucker and Paine and Lieutenant­ Colonel Haskin reporting to him. The left cannot be so well organized, owing to the intermixing of troops under different commanders. I would respectfully suggest that any future trouble liable to arise with regard to commanders be averted by orders from headquarters. To the left of Fort Totten there has been very little skirmish or picket firing. In front of Stevens and to the right and left of it firing is quite frequent. · The artillery firing has been from Stevens, De Russy, and Slocum for the purpose of shelling rebel pickets from cover of houses. No artillery or cavalry or any considerable body of infantry have been developed. Two prisoners belonging to a Georgia regiment, captured by our advanced skirmishers in front of Stevens, say they were of Colonel Cook's brigade, Rodes' division, Early's (formerly Ewell's) corps, consisting of divisions of Rodes, Gordon, and Ramseur; these directly in front of Stevens. The estimate placed upon this command, including Breckinridge's command, and the irregular Virginia troops is about 30,000, prisoners estimating from 25,000 to 50,000. General Meigs reports squads of cavalry seen to the right of Totten, thinks the enemy. The enemy maintain a pretty stiff picketline and are not easily driven. This part of the defense may be regarded as well organized. The line though not strongly defended is capable of resisting successfully a single line assault. A rebel sharpshooter just wounded severely a soldier standing on the parapet of Fort Stevens. I have the honor to be, sir, your obedient servant,

SIR: Returning on board this afternoon after having reported my anival in person at the Department, I received the Department's telegram of this date infonning me that the Department disapproves my leaving my station without ord~rs in an emergency like the present, and directing me to return to Hampton Roads without anchoring. I am deeply concerned at this censure of the Department and beg leave to state the circumstances which appear to excuse my coming to assist in the defense of the capital. It was known that a large rebel force was in Maryland and before Washington; that our forces had been defeated when attempting to repel this advance of the enemy; that the important military supplies at Baltimore and Annapolis had all been embarked ready for removal beyond the reach of the enemy; that the governors of States were trying to get out the militia.for the defense of the national capital; that the communications had been cut off by the enemy between Washington, Baltimore, and , and that the telegraph was not working. The Department's· telegram of the 10th instant was not received by me at Hampton Roads until 6 p.m. of the 11th instant. The defenses of Washington, 30 or 40 miles in length, owing to the reinforcements sent thence to the Army of the Potomac, were, it was understood, to depend upon a small garrison mostly of green troops. This defense had been strengthened by a detachment from the , and as represented in the public prints, by a detachment from the New York navy yard also, sent to man the fortifications around Washington. I had just sent a division of this squadron, consisting of four steamers with heavy batteries, to Washington, one of which was an ironclad. In James River and Hampton Roads all was quiet. Obstructions were down in·the river and the ironclads and gunboats were watching them and protecting, as for two •months past, the communications of the army. I had done all that was practicable to send cruisers from the roads after the Florida; also to dispatch the blockaders which had come in for coal and repairs to their stations off Wilmington. I respectfully submit that the emergency appeared to be not there, but here at the national capital. I did not know until my arrival here that large reinforcements had come opportunely from New Orleans, owing to the fortuitous circumstance that the orders for their leaving found them already embarked for an operation in another direction. Under these circumstances, but for the disapprobation expressed by the Department, I shouid have always felt .that I had acted well in the matter. The Malvern is now underway for Hampton Roads, where the other vessels from the ., squadron under my command are returning. I have the honor to be, si~, very respectfully, yours,

MY DEAR HALLECK: Order Barnard to send an officer of engineers to make a careful measured survey of the rebel trenches at FortStevens. McCook rode over the line with me, pointed out lines of battle, recognized by empty ammunition boxes, cartridge package wrappers, &c., and also camps, recognized by camp-fires and old hats, shoes, and the usual debris of such occupation. McCook feels strongly on the subject, and will go with the officer. In view of the Intelligencer's articles it will be well to have them recorded in official form and get it engraved and published in papers of large circulation.

I have the honor to make the following report concerning the amount of force I deem necessary to hold the defenses north of the Potomac against a coup de main or sudden attack such as we have recently been threatened with: One regiment of heavy artillery from Fort Sumner, Md., to Fort Reno, D.C.; one from Fort Reno, D.C., to Fort Stevens, D. C.; one from Fort Stevens to Fort Lincoln, D.C.: one south of the Eastern Branch, with three regiments of 100-days' men, or other infantry regiments, each 1,000 strong, and at least one company of mounted men to each brigade. These heavy artillery regiments should have now 1,000 men for duty. There is reason to suppose they would receive from 300 to 500 men in addition during the course of two or three weeks from different sources. There is a large amount of work to be done outside the line of forts within range of the guns, and a picket-line should be kept up throughout the line. There is little encouragement to teach 100-days' men the service of heavy guns, and they cannot be taught mechanical maneuvers in the time of their enlistment.

[CIRCULAR.] CHIEF QUARTERMASTER'S OFFICE, Washington Depot, July 19,_ 1864. The following extracts from letters of the Quartermaster-General, dated the' 16th instant, relative to the continuation of the military organizations of the employes of the Quartermaster's Department, are published for the information and guidance of the officers and employes of the depot: The organization of the clerks, workmen, and laborers of the Quartermaster's Department will be kept up; and to make it more efficient a certain time should be devoted to drill at regular periods. The officers should have letters of appointment from the Quartermaster-General, upon your nomination, unless the Secretary should consent to sign the appointments. This will be submitted to him. All persons employed by the department should wear the Quartermaster's Department badge, for which you will please make the necessary arrangements. Those who actually took the field during the late demonstration against Washington should wear this badge of white metal upon a patch of red cloth, circular in shape, showing one-eighth or one-quarter inch around the edge of the badge. By devoting a little time to this matter, I am of the opinion that a force of 5,000 or 6,000 effective men for the aid of the garrison at Washington can be raised. When tolerably familiar with the school of the soldier, they will be assembled in larger bodies and drilled occasionally by battalions and brigade. Those of the Quartermaster's Department should be organized into a brigade. The other Departments can probably furnish a second brigade, and the emulation between the two will have a good effect. Bugles, flags, and the necessary equipage for drill should be provided and placed in the armories. I prefer the bugle to the drum. Cooking equipage and shelter­ tents for as large a body as can probably be made movable should also be stored at some central armory, to be carried to the field when needed in wagons; knapsacks and blankets will not be wanted. The Quartermaster-General directs that the military organization of the depot employes into companies and regiments to for/n one brigade to be commanded by you (General D. H. Rucker)be made as soon as practicable. Each company will consist of captain, one first lieuten~t, five sergeants, five corporals, and 100 privates. Each_ regiment will have one colonel, one lieutenant-colonel, one major, one adjutant (a lieutenant), one quartermaster _and acting commissary of subsistence (a lieutenant), one sergeant-major, one quartermaster's sergeant, and one commissary sergeant. If a sufficient Civil War Defenses of Washing_ton pageH-15 Historic Resources Study Part I-Appendix H

number of musicians.can be found among the men each company will be allowed two. Suitable persons for the field and staff officers of regiments.and for line officers will be recommended to the Quartermaster-General. Their appointments will be subject to the revocation of the Quartermaster-General. The appointment of non-commissioned officers will be made as prescribed in the Anny Regulations. Colonels will be selected from the commissioned officers of the Anny and volunteers on duty at the depot; lieutenant-colonels in the same manner; majors from clerks and superintendents, captains from the superintendents, overseers, and wagon-masters, and lieutenants and non-commissioned officers from the same. All employes whose services can practicably and without detriment to the public service be spared will attend daily drills. Instructions will be given in Casey's Infantry Tactics, commencing with the school of the soldier; especial attention being given to the manual of arms, and that the men be habituated to load and fire with facility and accuracy. In view of furnishing uniform clothing to the.brigade, a list of the sizes with number of each size of the following-named articles will be made and forwarded to this office as soon as practicable, viz: Flannel sack-coats, trousers (foot), and forage caps. The clothing will not be issued until the question of such issue is decided by the Secretary of War, to whom itis to be submitted. Report the location of the armories, and what arrangements can be made for the preservation and care of the uniforms should they be issued for drill. The War ~epartment will be requested to order an officer of the Adjutant­ General's Department to report to the Quartermaster-General to act as adjutant and inspector of the whole organization. The organization of the companies and regiments to form the brigade as directed by the Quartermaster-General is intrusted to Capt. E. E. Camp, assistant quartermaster, to be assisted by Capt. Charles H. Tompkins, assistant quartermaster. These officers will enter upon this duty immediately and complete the organization with as little delay as possible. A list of the names of the regimental and company officers will be sent to this office as soon as the regiments are organized, together with a complete return of each regiment showing its strength and organization. The points at which the armories are located and where the several companies are directed to rendezvous will also be stated. Captain Camp is authorized to give all orders necessary to carry out the instructions of the Quartermaster-General and to perfect the organization required. D. H.

HEADQUARTERS HARDIN'S DIVISION, July 19, 1864. . SIR: I have the honor to make the-following report of the operations of my command on the 10th, 11th, 12th, 13th, and 14th instant: On the night'of the 10th I was ordered to make my headquarters at Tennallytown. I learned before leaving the city that Major-General McCook was to command a reserve force to be stationed at Crystal Civil War Defenses of Washington pageH-17 Historic Resources Study Part I-Appendix H

Spring. I left the city about 11 p.m. The last report from Major Fry, commanding the cavalry on the Rockville road being that he was falling back and would make a stand just outs1de of Tennallytown, the enemy pushing him back rapidly. Upon aniving at Foit Reno, headquarters First Brigade, Colonel Warner commanding, I felt assured there was not so evident danger to the defenses as I was led to suppose from the cavalry reports. Everything was very quiet. Colonel Warner had made good dispositions of his troops, and the Veteran Reserves were corning up rapidly: Colonel Gile, with First Brigade of Veteran-Reserves reported about midnight. Colonel Lowell, Second Massachusetts Cavalry, having moved out at daylight Monday morning, in command of all the available cavalry, commenced skirmishing. About 6.30 a.m. the enemy's . advance fell back several miles to their reserves, when they began forcing Colonel Lowell's command back. The enemy occasionally fired a small rifled gun near the road. Colonel Lowell remained on infantry picket-line. Cavalry scouts were sent out the River and Aqueduct roads. No enemy reported in that direction. Heavy clouds of dust and occasionally troops and wagons were seen from signal station at Fort Reno, moving apparently from Rockville in direction of Seventh-street pike. General McCook was notified, the skirmish line strengthened from Fort Reno to Rock Creek, and a proper disposition of the infantry supports made. Skirmishing was quite brisk on the right near Rock Creek until dark. During the night of the 11th the pickets were very much strengthened from Brookeville road to Rock Creek: One company of Veteran Reserves, under Captain Clark, Sixth Regiment Veteran Reserve Corps, made a gallant effort to take a barn which the enemy were using to advantage against our skirmishers in front of Fort De Russy. Captain Clark was slightly wounded and many of his company were wounded. These very efforts and the determined way of holding the picket-line showed the enemy that he would have to make a desperate assault to carry this portion of the line, which I believe one of the weakest points on the front. This resistance on the picket-line and the advance of the Sixth Corps skirmishers it is considered made the enemy think we were prepared for an assault. I respectfully call attention to the reports of the brigade commanders appended. Such telegrams as are in my reach are appended. Many, I think were carried off by the operators. My adjutant- . general had to remain in the city. I sent my inspector-general,.Captain Markle, to the Second Brigade. There did not appear to be sufficient attention paid to pickets on that front. He was put there to represent me as far as possible. I think the enemy would not have gotten so close to Fort Stevens if the picket-line had been strengthened as promptly as it was in the First Brigade upon the first appearance of the enemy's skirmishers. Upon personal application, I obtained a regiment from General McCook on Monday afternoon, after visiting Fort Slocum, to put out as a skirmish line, connecting with the Sixth Corps and reaching to the Eastern Branch. Before. this nothing but a line of observation had been before that front. No report has as yet been received from Colonel Lowell, commanding the cavalry. The enemy fell back Tuesday night. They were promptly followed up the Rockville road by Colonel Lowell's cavalry. Lists of killed and wounded are appended. Many wounded were sent at once into the city; it is very difficult to get accurate lists of them. . I have the honor to mention Col. J.M. Warner, First Vermont Artillery, commanding First Brigade, for his coolness and perfect understanding of his position; also Colonel Lowell, Second Massachusetts Cavalry, Civil War Defen~es of Washington pageH-18 Historic Resources Study Part I-Appendix H

commanding the cavalry. The information given by him was always reliable. I am indebted to Colonel Gile, commanding First Brigade, Veteran Reserve Corps, and to the officers and men of that corps for our principal success. I have the honor to mention my staff-:-Captain Chandler, assistant adjutant-general; Captain Markle, acting assistant inspector-general; Lieutenant Waterbury, Fourth New York Heavy Artillery, acting aide­ de-camp; Lieutenant Carroll, Fifth U.S. Artillery, acting aide-de-camp; Captain Nesmith, assistant quartermaster', and Lieutenant Hough, Ninth New York Artillery, ordnance officer; in so long a line, were kept almost constantly in the saddle and most cheerfully performed all duties required of them.

WASHINGTON, July 21, 1864-11.30 a.m. Lieutenant-General GRANT, City Point, Va.: General Barnard is ordered to report to you. Engineer officers have been sent several times to Baltimore to lay out the works. Some are there now. I think, from personal examination, that they are better located than the defenses of Washington. It appears that Early sent a small force south with his plunder, and massed the rest near Winchester. General Averell had a skirmish there yesterday, and reports having killed and wounded over 300 rebels, taking 200 prisoners and 4 pieces of artillery. Nothing heard from Wright for three days. When he received your orders he replied that he would return as soon as assured of rebel retreat. Your telegram about merging departments is in the hands of the Secretary of War. I have no good reason for removing or superseding General Augur. He is capable and efficient. General Franklin would not give satisfaction. The President ordered him to be tried for negligence and disobedience of orders when here before, but General McClellan assumed the responsibility of his repeated delays in obeying orders.

HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, July 22, 1864. Maj. Gen. C. C. AUGUR, Commanding Department of Washington: GENERAL: In compliance with your directions, I have caused the ground occupied by the rebel troops to be surveye9 and the locations of camps noted, and send you a sketch(*) herewith; also a report of Lieutenant Oberteuffer and Mr. Hergesheimer (U.S. Coast Survey) on the subject. No very definite statement of actual numbers was obtained, but it is certain that, besides the 1,500 cavalry which approached Tennallytown, on the Rockville road, and the cavalry which encamped at Silver Spring, very heavy bodies· of infantry came up on the Seventh-street road, bivouacking from Silver Spring to Batchelor's, two miles distant. Twenty pieces of artillery are known to have been brought up to Silver Spring and five pieces were with McCausland's command. The belief that ·a very considerable force advanced from Rockville to Leesborough on Monday was founded by myselfupon observations made from Fort Reno on Monday of dust; not upon any given appearance of dust at one moment, but upon the permanence of its exhibition at the same points, indicating the continued occupation of the road, by marching columns. For hours such dust clouds appeared on the road from Rockville to Leesborough on Monday; indeed they were seen by me from about 8 a.m. till 2 p.m., and observed by others during the rest of the day. The statement of persons in the vicinity confirm the observations from Fort Reno, as they generally give to the time the columns Were passing given points, both in advance and retreat; a duration of nearly twelve hours. The line marked "rebel skirmish line" was marked by the hasty cover of fence rails, earth, &c., thrown up, as well as by the retnnants of cartridges, .ammunition-boxes, and other relics. On the other side of the road in the woods opposite Silver Spring a line of relics has been traced which has been supposed to have been a line of battle, but which Lieutenant Oberteuffer considered a mere line of communication with the cavalry camp. I am, very respectfully, your most obedient,

J. G. BARNARD. P. S.-By orders from headquarters U.S. Army, I leave tomorrow to report to General Grant. .

[lnclosure.] HEADQUARTERS CHIEF ENGINEER OF DEFENSES, Washington, July 21, 1864. Maj. Gen. J. G. BARNARD, Chief Engineer: GENERAL: We respectfully report the following as the res_ult of our examination of the ground lately occupied by the rebels, made in obedience to your orders: The rebel force approached Washington by two roads from Rockville-the Seventh-street road and the turnpike road through Tennallytown. The force on the Tennallytown road was McCausland's brigade of cavalry and mounted infantry, consisting of five regiments, three of which were the Twenty-second Virginia Mounted Infantry, Twenty-second and Fourteenth Virginia Cavalry; in all, about 1,500 men, including Jackson's battery of artillery, five guns. This force arrived about 8 o'clock on Monday morning and left during Tuesday night and were picketed along the road both sides of the fences, extending from Mr. Hawn's house to the old church. The main force, under General Early, passed down the Seventh-_street road, the rear, consisting of Echols' and Wharton's brigades, reached and encamped on Mr. Batchelor's place about 6 o'clock Monday evening. Most of this force was encamped along the Seventh­ street road between Batchelor's and Blair's. Two small cavalry camps to the eastward, near the , were formed apparently as a rendezvous for roving bands of cavalry in search of horses, &c., and for observations on their extreme left. The road marked on the accompanying sketch,(*) passing by Judge Dunlap's house near Rock Creek, was used as a line of communication between McCausland's and the main force, and by General Williams' brigade of infantry on the retreat Tuesday afternoon. Mr. Batchelor, who lives on the Seventh-street road about two miles above Blair's, states that the rebels commenced passing his house toward Washington about 9 o'clock Monday morning (July 11). All of the cavalry had not passed until about 12 m., when they were followed by a body of sappers and miners, or infantry with picks and shovels, and that the infantry and artillery continued to pass constantly until 6 o'clock in the evening, when the rear guard, consisting of the brigades of Generals Echols and Wharton, encamped or bivouacked near his house on the side toward Washington. The rear guard remained near his house till Tuesday evening about 7 o'clock, when they were the first to commence the retreat, carrying the wagons with them. Mr. Batchelor states that he remained on his front porch all night while the rebels were retreating; that in the retreat there were only three halts of about fifteen minutes each, and that the rear guard, consisting of about 2,000 cavalry, had not all passed until 5 o'clock Wednesday morning. Mr. Batchelor estimates the artillery at twenty pieces. Mr. Davis, who the toll-gate at Silver Spring, saw the artillery pass his place to Blair's place, where it was parked, and estimates it at about twenty pieces. Mrs. Barnes, who lives at the upper end of Blair's place, was at home all the time the rebels were in the neighborhood. The first rebel killed by our pickets fell and was buried near her house. The rebels bivouacked around her house. She frequently heard their conversation, and from what she heard says their force was 30,000, and that their purpose was to make an attack early on Tuesday morning. Says she Civil War Defenses of Washington page H-22 Historic Resources Study Part I-Appendix H

frequently saw Generals Early and Breckinridge, and was questioned by General Early as to the number and characters of the garrisons of the forts in front. Very respectfully submitted. J. H.

HDQRS. FIRST BRIGADE, VETERAN RESERVE CORPS,

Washington, D.C., July 22, 1864.

COLONEL: I have the honor to make the following report of the operations of the First Brigade, Veteran Reserve Corps, during the late rebel invasion: Pursuant to orders received from headquarters Military District, dated July 10, 1864, the Ninth Regiment Veteran Reserve Corps, Lieut. Col. R. E. Johnston commanding, left Camp Fry, D.C., at 4 p.m. and reported to Major-General McCook, commanding at Crystal Spring, Md., at 8 p.m .. and bivouacked for the night, the rest of the brigade remaining in camp (with orders to be ready to move at short notice) until 6 p.m., when I received orders to report without delay to you. I immediatelY, ordered the regiments of the brigade to rendezvous at Camp Fry, and at 9 .15 p.m. the brigade took up the line of march, arriving at Tennallytown at 11.15 p.m., when, in accordance with your instructions, the following disposition was made of the command: The Twenty-second Regiment Veteran Reserve Corps, Lieut. Col. A. Rutherford commanding, was placed in the rifle-pits in front of Fort Sumner; the Sixth Regiment Veteran Reserve Corps, Lieut. Col. F. S. Palmer commanding, in rifle-pits on the left of Fort Reno and directly in front of Tennallytown, its right resting on the Rockville pike; the First Regiment Veteran Reserve Corps, Lieutenant­ Colonel Trotter commanding, on the right of Fort Reno in the rifle-pits; the Nineteenth and Twenty-fourth Regiments, commanded respectively by Col. 0. V. Dayton and Maj. J. W. H. Stickney, massed in column of division directly in rear of Fort Reno. The brigade bivouacked for the night, and at I a.m. July 11th the Ninth Regiment formed line of battle and remained in that position until 7 a.m., when they were ordered to occupy the rifle-pits on the left of Fort Stevens. The Twenty-fourth Regiment was then moved to Fort Mansfield, the remainder of the . brigade remaining in the same position, excepting one company of the Nineteenth Regiment, which was thrown out on the Rockville pike as pickets, and shortly afte~ taking its position was attacked by the enemy, but held its position until relieved, with a loss of 2 men wounded. At 2.30 p.m. orders were received making the following changes in the line: The First Regiment was sent from Fort Reno to rifle-pits on the left of Battery Smead; the Sixth and Nineteenth Regiments to Fort De Russy, the former, occupying the rifle-pits on the right of the fort and reaching to Rock Creek, the latter in the rifle-pits connecting Battery Smead and Fort De Russy. The Twenty-second Regiment moved from Fort Sumner to Fort Civil War Defenses of Washington pageH-23 Historic Resources Study Part I-Appendix H

Kearny and took possession of the rifle-pits in front of the fort. At 4 p.m. the Ninth Regiment was o~dered to advance as skirmishers and relieve the Twenty-fifth New York Cavalry (dismounted). After a brisk engagement, in which the regiment lost 1 killed and 11 wounded, they succeeded in relieving the cavalry and advancing the line some distance to the front, and remained on the skirmish line until the advance of the Sixth Corps, Army of the Potomac, which relieved seven companies, three companies remaining on the line. After 5 p.m. three companies of the Nineteenth Regiment Veteran Reserve Corps, one company of the Sixth and one company of the First Regiments were deployed as skirmishers in the front and on the flanks of Fort De Russy and Battery Smead, and succeeded in advancing the line some 1,50Q yards to the front. The same hour the Twenty-fourth Regim_ent was ordered from Fort Mansfield to Fort De Russy, and shortly after arriving at that point was sent back to Fort Reno, occupying the rifle-pits on the right of the fort. At 7 .30 p.m. the enemy was seen re-enforcing his lines. I accordingly sent the Sixth Regiment to strengthen the skirmish line on the right and Center, and six companies of the Twenty-second Regiment on the left of the line. Our skirmish line now extended from the Rockville pike on the left to about 2,000 yards beyond Rock Creek on the right. At 3 a.m. July 12 the whole command was under arms. At 6 am. I ordered Col. F. S. Palmer, commanding the right of the skirmish line, to advance his line and take possession of a hill about a quarter of a mile in advance, then occupied by rebel sharpshooters, who were annoying our line very much. This was accomplished after considerable resistance from the enemy, with the loss of 1 man wounded. The left and center of the line, which was composed of three companies of the Nineteenth Regiment and six companies of the Twenty-second Regiment, also moved forward until the left of the line was nearly two miles in advance of the defenses. At 7 o'clock the Twenty-fourth Regiment moved from Fort Sumner to Fort Kearny. At I p.m. I relieved the Sixth Regiment, which was on the skirmish line, by the First Regiment Veteran Reserve Corps. At 2 p.m. I received ord1;:rs to send one regiment to Fort Reno. My command at that time was in such a position that I was compelled to send the Sixth Regiment, which had just been relieved from picket. This regiment on arriving at Fort Reno was ordered to occupy the rifle­ pits extending from Fort Reno to the left of the Rockville pike. In addition to this it furnished three commissioned officers and eighty-two enlisted men for picket. At 5 p.m. the First Regiment was relieved by the Twenty-fifth Regiment New York Cavalry (dismounted) and occupied the rifle-pits vacated by the Sixth Regiment. Having received information that the enemy were planting some artillery on the right of a building in front of our lines, at 5 p.m. I ordered Captain Clark, Company H, Sixth Regiment, to advance his company and ascertain if such was the fact, and if so, to bum the building occupied by the rebel sharpshooters. He obeyed the order promptly and drove the rebel skirmishers beyond the building, but was here confronted by a reserve of about 200; maintaining his position he made a personal observation and found the report to be incorrect, when in obedience to instructions from me he withdrew his force in a manner highly creditable to himself and men. Captain Clark and four of his men were wounded in this reconnaissance. At 7 .30 p.m. the enemy sent forward a force to strengthen their line on o~r right. A sharp skirmish ensued in which the enemy was compelled to withdraw. · At 12 p.m. I received orders to have the command up and under arms at once, which order I complied with and remained in that position until 5 a.m. July 13, when I sent out one commissioned officer and ten privates to reconnoiter and ascertain the whereabouts of the enemy. They advanced several miles and found' that they had withdrawn their picket-line and retreated during the night. This fact I immediately reported to headquarters. At 7 .30 a.m. six companies of the Sixth Regiment were ordered to proceed Civil War Defenses of Washington pageH-24 Historic Resources Study Part I-Appendix H

about six miles on the Rockville pike, to support a section of artillery and Colonel Lowell's cavalry, then engaging the enemy. At 12.30 p.m. all troops of the brigade then on the skirmish line, except the Ninth Regiment, were relieved and took their former positions in the rifle-pits. At 2 p.m. the Sixth Regiment returned to Fort Reno. At 8.40 p.m. I received your order to report with my command without delay to General De Russy at Arlington. This order was obeyed as promptly as possible, and at 2 p.m. July 14 I reported with all my command, except the Ninth Regiment, to General De Russy. Our loss during the skirmish in the defenses north of the city was:(*} The conduct of officers and men of the various regiments of the brigade was unexceptionable. I should deem it unjust to particularize those whom opportunity made conspicuous, satisfied that all fully appreciated the great responsibility resting upon them, knew their duty, and performed it. Regimental reports+ herewith inclosed rehearse in detail the several duties performed by them during our brief campaign. All of which is very respectfully submitted by very respectfully, your obedient servant,

GENERAL: In obedience to Special Orders, No. 9, dated headquarters Northeast Defenses of Washington, D.C., Fort Lincoln, July 11, 1864, I have the honor to forward the military history and operations of the Second Regiment District of Columbia Volunteers, commanded by Col. C. M. Alexander. On the 10th instant we received orders to strike tents at Edsall Station, Va., where we were then stationed, and report to Maj. Gen. C. C.-Augur. Having reported, the regiment was ordered to report to Major-General McCook, commanding reserve camp near Fort Stevens, D. C. We arrived there about 9 a.m. on the 11th instant, and about 11 p. m. we manned the breast­ works and rifle-pits on the right of Fort Stevens. At 1 p.m. of the same date a detail of 100 men was sent out as skirmishers, and at sunset they were relieved by a portion of the Sixth Army Corps. On the 12th instant, about4 p.m., we were relieved by the Second Provisional Regiment, and were ordered to move to the rear of Fort Slocum. The regiment laid there until 9.30 p.m., when we were ordered to report to Major-General Gillmore at Fort Saratoga. We encamped for the night near Fort Thayer. On the morning of the 14th instant we were ordered to report to Brigadier-General Paine at Fort Slocum. At that time Colonel Alexander was placed in command of the First Provisional Brigade and the command devolved on Lieut. Col. William 0. Drew. On the 15th instant Colonel Farnsworth, then commanding Second Reserv~ Brigade, was ordered to report for duty at Alexandria, Va., and the command of the brigade was on Lieut. Col. William 0. Drew, and from that date the regiment was and is commanded by Capt. William F. Steele. Civil War Defenses of Washington page H-26 Historic Resources Study Part I-Appendix H

Although the skirmishing was very brisk there have been no casualties to our knowledge. The whole regiment signified their willingness to take position in the skirmish line, but owing to short range and inferior kind of arm the commanding general deemed it inexpedient for them to expose themselves unnecessarily.

COLONEL: I have the honor to submit a succinct report of the military operations in front of Washington, D.C., pending the advance upon it by a portion of the rebel army commanded by General Early. Reporting in person at the War Department on the morning of July 10, I was directed to report to Maj. Gen. H. W. Halleck. U.S. Army, who assigned me to duty in the Department of Washington, to command a reserve camp to be located on or near Piney Branch Creek, about midway between Washington and Fort Stevens on the north. In company with Lieut. Col. B. S. Alexander, U.S. Engineers, I at once proceeded to examine the ground for the camp, also to make a hasty examination of the fortifications on the north of Washington. Returning at 6 p.m., and receiving my final instructions from Maj. Gen. C. C. Augur, commanding department, I proceeded to Piney Branch, where the Second Regiment District of Columbia Volunteers, Colonel Alexander, and the Ninth Regiment Veteran Reserve Corps, Lieutenant-Colonel Johnston, Captain Gibbs' (Ohio) battery, and Captain Bradbury's (Maine) battery had already reported. Civil War Defenses of Washington pageH-27 Historic Resources Study Part !~Appendix H

Monday morning discovered the fact that the only troops on the north of Washington were the small garrisons in the forts, small detachments of cavahy in the front, and the troops above mentioned. Hearing of the near approach of the eneniy, the idea of a reserve camp was at once abandoned and every man was brought forward and posted in the rifle-pits to the best advantage, and as strong a skirmish line as was prudent established. During the morning several additional regiments of the Veteran Reserve Corps and several detachments of dismounted cavalry reported for duty. They were posted in the rifle-pits on either side of the main road leading to Silver Spring. Captain Berry, of the Eighth Illinois Cavalry, being stationed with his company on the road leading from Silver Spring to Leesborough, dispatched a courier at 10 a.m. the 11th,_ informing me that the enemy was advancing in force on that road with infantry, artillery, and cavalry. At 12 m. a strong line of the enemy's skirmishers came in view, advancing upon our position. The picket-line at this moment was composed of 100-days' men of One hundred and fiftieth Ohio, and a portion of the Twenty­ fifth New York Cavahy (dismounted). Being satisfied that they could not contend favorably against the enemy's line, were ordered to fall back slowly, fighting, until they reached the rifle-pits. Fire was then opened at proper points upon our line, and the enemy was held in check until the dismounted of the Second Division of the Cavalry Corps, Army of the Potomac, 600 strong, commanded by Maj. George G. Briggs, Seventh Michigan Cavalry, were made ready to go out, drive the enemy back, and re-establish our picket-line. This was handsomely done about 1.30 p.m., the enemy's skirmishers being forced back, and our line well established at 1,100 yards in front of the works. The enemy not developing any force other than their skirmish line, affairs remained in this condition until evening. About 3 p.m. Maj. Gen. H. G. Wright, U.S. Volunteers, commanding the Sixth Army Corps, reported to me at Fort Stevens, infonning me that the advance of his corps would be up in a short time. I directed him to furnish a force 900 strong of this veteran corps for picket duty during the night, constant skirmishing being kept up between the lines until after dark on the 11th instant. At 9 p.m. Brig. Gen. M. C. Meigs, Quartermaster-General U.S. Army, reported at Fort Stevens with about 1,500 quartermaster employes, armed and equipped. They were at once ordered into position near Fort Slocum, placed on right and left in rifle-pits. At 10 p.m. Colonel Price reported with about 2,800 convalescents and men from hospi,tals, organized into a provisional brigade composed of men from nearly every regiment of the Army of the Potomac. They were ordered into position in rear of Fort Slocum, as information received led me to believe that the enemy would demonstrate farther to our right. At 12.30 a.m. on the 11th the following telegraphic order was received: Major-General Gillmore, U.S. Volunteers, with a portion of the Nineteenth Corps, is assigned to command the line from Fort Lincoln to Fort Totten. Brig. Gen. M. C. Meigs, Quartermaster-General, to command the line from Fort Totten to Fort De Russy. Brig. Gen. M.D. Hardin, U.S. Volunteers, to command from Fort De Russy to Fort Sumner, inclusive. The Sixth Corps, Maj. Gen. H.G. Wright, U.S. Volunteers, commanding, to be held in reserve, and the entire line, and troops to be commanded by Maj. Gen. A. McD. McCook, U.S. Volunteers. · This order was complied with, with the exception to hold the Sixth Corps entire in reserve. I deemed it absolutely necessary that the immediate front should be picketed by experienced men. At dawn on the morning of the 12th the sharpshooters of the enemy opened fire upon our skirmish line, which had beeri intrenched during the ~ght. This fire was kept up from both lines Civil War Defenses of Washington page H-28 Historic Resources Study Part !~Appendix H

during the day. The enemy, on retiring their line on the evening of the 11th, seized and retained possession of a house on the right of the Silver Spring road, situated on an elevated piece of ground, surrounded by an orchard and large shade trees (Rives), which afforded excellent cover for sharpshooters, and commanded our advance line. They also posted sharpshooters in Mrs. Lay's house to the left of the road. From these two points our skinnish line was very much annoyed by the enemy, they killing and wounding about 30 of our skinnishers during the day. I determined these two points must be carried. General Wright was ordered to furnish a brigade to make the assault (as I had failed to carry these points with Captain Beattie's sharpshooters, of General Getty's division, Sixth Corps). Brig. Gen. , U.S. Volunteers, was ordered to direct th1::_moye_m~n~ of_th~_~SSflultj_pg tr_Qops. These troops having gained their position previous to assault at about 6 p.m., the two positions held by the enemy were vigorously shelled from Fort Stevens. Then at a signal Wheaton's troops dashed forward, and, after a spirited contest, gained the ground. This attack developed new forces ofthe enemy that had been concealed in a ravine beyond Mrs. Lay's house, and in the depression beyond the copse on the right of the road. The enemy's line was re-enforced by at least a brigade, the contest was kept up until after dark, we having gained all the ground desired, and rude intrenchments were thrown up upon it. That night the enemy withdrew their forces from our front. At dawn on the 13th none of them could be seen. Two companies of infantry were at once deployed as skirmishers, their flanks covered by a few mounted men, and pushed forward to gain all the information possible. Going forward in person I found nothing but the deserted camps of the enemy, and a few stragglers; also a hospital at Sligo Post-Office, containing about 70 rebels wounded too severely to be moved, 11 of them commissioned officers, including surgeons and attendants-about 90 in all. The prisoners taken between Fort Stevens and Leesborough numbered not less than 200, including the hospital. The number killed and wounded of the enemy I am unable to state, as all those who could be transported were taken away. Their loss must have been equal to, if not greater than, ours, our loss being about 250 killed and wounded. The Sixth Corps marching next day, I am unable to give the loss accurately. A special report should be made by General H. G. Wright, commanding the corps, and it is . left to him to do justice to the gallant officers and men of his command who behaved so well in this spirited affair-small, yet a very important one, as it was one of the causes that induced the enemy to abandon their idea of attacking Washington. I am satisfied the rebel force which confronted Washington was not less than 30,000. Ewell's old corps (entire), consisting of three divisions, commanded respectively by Generals Rodes, Gordon, and Ransom, was encamped upon F. P. Blair, sr. 's, farm. Breckinridge's command, consisting of about 10,000 infantry, was farther back and in the vicinity of Lees borough. My estimate of their forces was made from the most reliable sources possible, and all evidences show their force to have been divided as follows: Ewell's old corps (infantry) 12,000 Breckinridge's corps (infantry) 10,000 Artillery 1,000 Cavalry 7,000 Total 30,000 Civil War Defenses of Washington pageH-29 Historic Resources Stµdy Part I-Appendix H

Having instructions to hold the Sixth Corps in reserve, a further explanation may be necessary for the attack ordered on the evening of the 12th: First. The points assailed were commanding ones when in possession of the enemy enfiladed and commanded a portion of the picket-line necessary to be maintained in front of the works. Second. These points in our possession gave us observation over a ravine to the left and a depression of ground on the right of the Silver Spring road, not in view from the forts, and in which the enemy could mass a large force. Third. It was believed that the veterans of this corps could do the work better, and with less loss of life, than the other troops under my command. There are other and minor reasons, but these are deemed sufficient. __ My thanks are due to Maj. Gen. H. G. Wright, U.S. Volunteers, for his earnest co-operation in every duty. To Brig. Gen. M. C. Meigs, Quartermaster-General U.S. Army, commanding the line from Fort Totten to De Russy, my thanks are due for his willing and untiring discharge of duty. Brig. Gen. D. H. Rucker, U.S. Volunteers, commanding quartermaster employes; Brig. Gen. H. E. Paine, commanding line on right of Fort Stevens, and Brig. Gen. M.D. Hardin, U.S. Volunteers, commanding the line from Fort De Russy to Sumner, have my thanks for their valuable assistance in properly maintaining the portions of the line intrusted to their care. Lieut. Col. B. S. Alexander, U.S. Engineers, was of great service in furnishing maps and explaining lines and roads. Capt. Charles Dupont, Thirteenth Michigan Battery, deserves great credit for the skill displayed in directing the artillery of Fort Stevens . . Lieutenant-Colonel Frazee, One hundred and fiftieth Ohio (100-days' men), displayed efficiency and zeal during the 11th and 12th instant. The officers and soldiers of the Veteran Reserve Corps deserve great commendation for the prompt and zealous discharge of ev~ry duty in their power to perform. I would respectfully recommend that this corps be armed with the improved muskets. The Second Regiment District of Columbia Volunteers is also armed with the old musket. A change is also recommended for them. I regret that I cannot at this distant point recall the names of the commanders of detachments who reported to me, but I may hazard the remark, there never was before a command so heterogeneous, yet so orderly. The hale and hearty soldier, the invalid, the convalescent, the wounded, and the quartermaster's employes, side by side, each working with a singleness of purpose and willing to discharge any duty imposed upon him. I am under obligations to the following officers, acting upon my staff, for untiring attention to duty: Col. N. P. Chipman, aide-de-camp; Maj. S. B. Hayman, Tenth Infantry; Maj. Caleb Bates, aide-de-camp; Maj. R. T. Auchmuty, assistant adjutant-general; Major Hastings, Berdan Sharpshooters; Lieutenant Snow, Maine artillery; Lieutenant Welles, First Connecticut Cavalry; Captain Wells, assistant quartermaster. The following recommendations are respectfully made: First. That a monthly inspection be made by a competent engineer officer of all the defenses around Washington; that the ground in front of Civil War Defenses of Washington pageH-30 Historic Resources Study Part I~Appendix H

them be well cleared and kept so. Second. That a proper supply of assorted small-arm ammunition be kept constantly stored in the respective forts upon the line. All of which is respectfully sub~tted.

QUARTERMASTER-GENERAL'S OFFICE, Washington, July 25, 1864. COLONEL: On Saturday, the 9th of July, after consultation with the Secretary of War, I directed the clerks of the Quartermaster-General's Office, and the clerks and workmen employed by the officers of the quartermaster's department in the District of Columbia and in Alexandria to be organized and armed. On Sunday, the 10th, arms were procured from the arsenal; they were distributed on that day and on Monday. Such an organization had been made over a year since, but the arms then issued having been recalled, the organization in the departments of Washington and Alexandria had not been kept up. Lieutenant-Colonel Greene, chief quartermaster of the Military Department of Washington, however, under instructions from Major-General Augur, had retained the arms issued to the men employed under his direction, and had preserved the military organization. Under orders of the Secretary of War, I reported to Major-General Halleck, chief of staff, late on the evening of the 9th, for such field services as would not too much interfere with my duties as Quartermaster-General, and was directed to provide for relieving the guards of the quartermaster's stores, and some of the public buildings by the organized clerks and operatives of the Quartermaster's Department. Finding that a movable force more than sufficient for this duty could be furnished by the Quartermaster's Department, I offered their services to Major-General Augur, commanding the Department of Washington, and on the 11th July, it being reported that the enemy was advancing upon the Seventh-street road, I was requested to send them to report to Major-General McCook, headquarters at Fort Stevens. The battalion of clerks of the Quartermaster General's Office, about 250 strong, relieved the guards of the storehouses, corrals, &c., of the depots and of the public buildings, enabling the soldiers there employed to go to the front. The arrival without wagons or horses of portions of the Sixth Corps from the Army of the Potomac, and of the Nineteenth Corps from New Orleans, requiring new outfits of transportation, made it necessary to leave in the city a large portion of the wagon-masters, operatives, and teamsters, and reduce the movable force in the Washington. depot to about 1,900 men, of which 1,500 were placed under the immediate command of Brig. Gen. D. H. Rucker, and with them I reported to Major-General McCook about sunset on the 11th; and was directed to Civil_ War Defenses of Washington pageH-31 Historic Resources Study Part I-Appendix H

march to Fort Slocum and place the men as might be advised by Colonel Haskin, commanding the forts on the right. Colonel Haskin supplied a staff officer to point out in the darkness the line of rifle-pits extending from Fort Stevens to Fort Totten; about one mile in length. The men were posted therein and lay upon their arms all night. The next morning, 12th, I received Special Orders, No. 2, from Major-General McCook's headquarters, and assuming command of the troops in the intrenchrnents from Fort Stevens to Fort Totten, I proceeded to organize them into a division of three brigades as follows: First Brigade, Brig. Gen. D. H. Rucker, composed of the quartermaster's men of the depot of Washington, with a detachment of the Provisional Brigade, occupied the intrenchrnents on the right between Forts Stevens and Totten. Second Brigade, Brigadier-General Paine, composed of the Twelfth Veteran Reserves, the Second District of Columbia Volunteers, and three companies of the quartermaster's men of the depot of Washington, occupied the intrenchments on the left, between Forts Slocum and Stevens. Third Brigade, commanded first by Colonel Price, of the [Seventh] New Jersey Volunteers, then by Col. A. Farnsworth, Twelfth Veteran Reserves, and afterward by Colonel Alexander, of the Second District of Columbia Volunteers, a provisional brigade of these regiments, organized from the hospital and convalescent and distribution camps o( the Department of Washington. It was placed in reserve and bivouacked in rear of Fort Slocum in the center of the line. The garrison of the two forts, Slocum and Totten, were a separate command, under Colonel Haskin, U.S. Army, and though at first ordered to report to me the order was soon afterward revoked. Finding, however, that the garrison of Fort Slocum was not as strong as it should be, I ordered Colonel Price, then commanding the Provisional Brigade, to ascertain the number of artillerymen in his command and to send them to report to Colonel Haskin at Fort Slocum. The garrison thus received a re-enforcement of 105 trained artillerists. The division thus organized on the morning of the 12th July, had an effective strength present for duty of 4,914 men and officers with one section of light artillery, which was placed in one of the trenches on the left. During the 12th the enemy made their appearance in front of Fort Stevens, and a portion of the command, which had been placed on the skirmish or picket-line, was engaged. But two casualties have been reported to me among civilians of the Quartermaster's Department. A battalion of three companies of quartermaster's men of the depot of Washington had moved out to Fort Stevens under orders from Major-General Augur only on the 11th, and a portion of these were engaged in the skirmish in front of Fort Stevens on the 12th. John Rynders, a member of Company B, was slightly wounded in the arm, and a former employe of the Quartermaster's Department, who accompanied Company Bas a volunteer, was shot through the body and almost instantly killed. He was buried with the others who fell in the skirmish, and I regret that I have not yet been able to ascertain his name; when found it will be placed upon his grave, now marked "unknown," in the cemetery set apart by order of the Secretary of War for those who fell in the defense of the capital on the 12th July. Civil War Defenses of Washington pageH-32 Historic Resources Study Part i-Appendix H

Four hundred men were detached from the command on the 12th to be placed on the picket~ line by staff officers of Major-General McCook. The Twelfth Veteran Reserve and the Second District Columbia were relieved from duty in the trenches about 4 p.m. of the 12th July, by two regiments of the Provisional Brigade, and were themselves placed in the reserve until about 9 p.m., at which time, under instructions from General McCook, they were ordered to march to Fort Saratoga to report to Major-General Gillmore, who had asked for re-enforcements, and were encamped for the night near Fort Thayer, where they remained during the 13th. On the 14th these two regiments, by order of Major, General McCook, returned to my command. The forces of this division had been hastily organized and sent to the field in an emergency and without baggage. They wete supplied during the 12th and 13th with shelter-tents, blankets, and such equipage as was necessary to their comfort and health while on duty in the trenches. On the 14th, under orders-from Major-General Augur, the enemy having retired from the front, the quartermaster's men were relieved from duty in the trenches, and I turned over the command of the remainder of the division to Brigadier-General Paine, and directed General Rucker to march the civilians to Washington and return them to their regular duties, but to keep up their military organization and drill. . Major Darling, of the Seventh Michigan Cavalry, commanding cavalry outpost, with a force of about 460 cavalry, operated in front of the extreme right toward Baltimore turnpike and railroad. He sent me information on the afternoon of the 12th that his force had been driven in by a strong body of cavalry and artillery, which interrupted the travel for a time and injured the railroad to a small extent. The day was hot and dusty, and the movements of the cavalry could be traced from the forts by the columns of dust which they raised. The enemy came as far as the Maryland Agricultural College, and when they retired were pursued by our cavalry, who being in inferior force and without artillery, appeared to be repulsed in their attack. After relinquishing the command of the division to General Paine, I spent some hours in riding over the scene of the conflict and visiting the bivouacs and line of battle of the enemy in front of Fort Stevens. From the extent of ground occupied by them they appeared to have a strong force within supporting distance of the skirmishers, which alone seemed to be engaged. The three companies of the quartermaster's men, organized under Lieut. Col. E. M. Greene, chief quartermaster, Department of Washington, who were on duty during the affair of the morning of the 12th in the trenches between Forts Stevens and Slocum with General Paine's brigade, were ordered on the afternoon of that day to report to General Rucker. Through some misunderstanding two companies, B and C, marched to General Rucker's office in Washington. Company A reported at his headquarters in the field and remained on duty until the brigade was relieved. The quartermaster's men of the Department of Washington, south of the Potomac, were organized into five companies, making a force of about 400 men. Companies E and F were, at the request of Brigadier-General Slough, commanding at Alexandria, detailed and placed on picket duty around that city. The other companies were placed in reserve at the wood-yard, drilling constantly, and held in readiness to defend the public property. The employes of Capt. J. G. C. Lee, assistant quartermaster, at Alexandria, were also organized Civil War Defenses of Washington pageH-33 Historic Resources Study Part I-Appendix H

and placed on duty. The whole civil force of the quartermaster's department on military duty on this occasion was about 2,700 men. I have to express my satisfaction with the conduct of both the soldiers and civilians who were under my .command. Though hastily organized and equipped they moved promptly at the call of danger. I had on no occasion to inflict punishment or administer reproof during the time they were under my observation, and their services were useful and important in the defense of the capital, seriously threatened by a considerable rebel army under skillful and experienced leaders. Those who were on duty in the city relieved at least an equal number of trained soldiers and enabled them to go to the front, while those who were placed in the intrenchments extended the line of battle fully a mile to the right of the center of attack, and by their presence and bearing, standing upon the parapets and exposing themselves, perhaps, more than more experienced soldiers would have done, they convinced the enemy th~t the fortifications of Washington were not unmanned. I inclose such reports as I have received from subordinate commanders, and remain, very respectfully, M.C.MEIGS, Quartermaster-General, Brevet Major-General. Lieut. Col. JOSEPH H. TAYLOR, Chief of Staff and Assistant Adjutant-General. [lnclosure.] Extract from letter of Bvt. Maj. Gen. M. C. Meigs, dated Washington, D.C., July 16, 1864.

Twice while McClellan was on his way to the James, or there, they did by the Shenandoah put Washington in danger; but there were troops here then to defend it: now with an enterprising and uniformly successful commander, a larger army, trained to confidence and success through three years of doubtful conflicts and two months of most bloody, desperate, and successful fighting, the crippled army of Lee, relying upon the intrenchments of Richmond and the weakness of the Washington garrisons, sends again by the familiar road a column of 25,000 or 30,000 men, breaks communications north and east of Baltimore, defeats a veteran division of the Army of the Potomac (Ricketts') hastily thrown across the line of march, drives Wallace' and Ricketts back upon Baltimore, and sending small parties to alarm and raise the neighborhood, to burn the house of the Governor, and prevent the troops of the north passing beyond, alarmed Baltimore, this column concentrates suddenly upon the north front of Washington. The invalids, now called Veteran Reserves, of the police garrison of Washington, are relieved from guard duty by the clerks of the Quartermaster­ General's Office. The old soldiers in hospital and in convalescent and distribution camps are hastily organized into provisional regiments, dismounted cavalrymen, for whom horses are not here, are sent into the trenches to act as infantry, and the mechanics, agents, clerks and overseers, and laborers of the depot quartermaster, who can for a day or two in emergency be detached from their ordinary duties, are organized and armed, and marched to the trenches. The head of the column of the Sixth Corps of veterans from the Army of the Potomac arrives from Petersburg on I

Civil War Defenses of Washington pageH-34 Historic Resources Study Part I-Appendix H

the day that the head of the Nineteenth Corps reaches Washington from New Orleans, and on the very day that the rebels send their skirmishers within forty rods of the salient of Fort Stevens, and within sight of Fort Reno. The former on the Seventh-street road, and the latter on the Rockville or Tennallytown road. On Monday morning at daylight our cavalry was sent out the Tennallytown road to force the enemy to develop himself in line of battle. A handsome skirmish showed at this point in front of Reno about 1,200 cavalry and a horse battery. Later in the day General McCook · reported the rebels were advancing in force. I had offered the services of the quartermaster's men, of whom we had about 3,000 armed, who were disposable for this purpose, to General Halleck. He thought that it would be enough for them to guard the stores in the city against riot or incendiary attempts. I then offered them to General Augur, commanding the forces, and he gladly accepted them and requested that they be sent to Major-General McCook at Fort Stevens, on the Seventh-street road. I called the men out; 400, who were under General Augur's quartermaster, had been sent out in the morning, 700 more had gone to the lines in front of Alexandria, and I marched about 5 p.m. with 1,500 or 2,000 toward Fort Stevens. Reported to McCook just as it grew dark, and he sent an officer from Fort Slocum to point out the position he wanted us to occupy. We found it as well as we could in the darkness. The new moon gave a little light and our forces, which th~ next morning numbered 1,500, extended McCook's line just one mile to the right of the center of attack. We bivouacked on this line, part of the men in the trenches, the rest close in the rear. I slept in an orchard wrapped in a poncho, with my horse tethered to an apple tree. The next morning I was ordered to take command of all the troops and defenses from Fort Stevens to Fort Slocum and thence to Fort Totten, and found myself in command of a division 5,000 strong, which I organized,.at once into three brigades, General Paine commanding the rifle-pits held by the left wing, General Rucker the right wing, and placing a provisional brigade under Colonel Farnsworth in the rear of Fort Slocum in reserve. We got up wagons, rations, shelter-tents, Cooking utensils, intrenching tools, axes, and worked to perfect the defenses and clear the timber and brush from our. front. During the day skirmishing was continuous in front of Stevens, where the advance of the Sixth Corps of veterans, under General Wright, engaged the enemy. I detached 400 men to a commander away to the left to go on picket. One hundred and five artillerists I found in the Provisional Brigade and sent them to report to Colonel Haskin, to strengthen Fort Stevens battery. The day wore away. I visited the lines to my right, in which no troops occupied the trenches or rifle-pits. The forts, however, which are about a mile apart and on commanding positions, were garrisoned. General Gillmore was at Fort Saratoga, several miles to the right, and toward evening telegraphed for re-enforcements, and I sent him 2,000 regulars, nearly the whole of my reserve, by order of General McCook. We received orders to have all our troops under arms at 3 o'clock next morning. Toward evening two houses which were occupied by the rebel sharpshooters on the Seventh-street road, some three-quarters of a mile in advance of the lines, were burned by shells from Forts Stevens and De Russy, and our skirmishers, after a sharp contest, costing each party 300 casualties, occupied their ruins and drove back the rebels and intrenched themselves. I was up at 2 o'clock, my men were all under arms, and I rode to Fort Stevens and took position on the parapet to watch the breaking day. The gray dawn spread over the landscape widely Civil War Defenses of Washington pageH-35 Historic Resources Study Part I~Appendix H

extended in sight. An occasional shot from a suspicious picket and the low of a cow or the bray of a mule alone broke the stillness of the inoming, and at last the sun arose and all remained quiet. Cavalry were sent out, who reported the rebel positions abandoned. The house of the Postmaster­ General, , two miles out Seventh-street road, burned; old Francis P. Blair's house, on the farm, turned topsy-turvey, all his liquors consumed, and his papers ransacked, and the enemy in retreat toward Rockville and the fords of the Potomac. We remained in position till full daylight, and then sent the men to their breakfast and continued our work of clearing off obstructions to our fire and completing our intrenchments. I rode along the lines right and left. In the course of the day an officer from the War Department handed me a letter from the Secretary, notifying me that the President had appointed me a major-general by brevet in the United States Anny, and I accepted and thanked the President and Secretary for the honor and confidence. The commission happened to find me exercising a full major-general's command. I had command of the right wing of that portion of the army which was directly in front of the enemy; my command extended in line of battle two miles, and was 5,000 strong. The next night we had an alarm. Some fellow with the nightmare rushed screaming through camp, "the rebs, the rebs are on us!" The men caught up their arms and rushed into the trenches; they behaved well in this most trying of all circumstances-a night alarm. Horses were saddled, inquiry made, and all found quiet. · The next day the enemy having retired, the two regiments I had detached to Gillmore returned to me. Gillmore followed Wright in pursuit of the retreating enemy. I had orders to return to Washington and release my volunteer civilians and return them to their ordinary work. All this time the Quartermaster's Department was fitting out the troops which arrived from Petersburg and New Orleans with horses, wagons, or artillery. We mounted 2,000 or 3,000 cavalry; gave 1,000 or 2,000 horses to horse artillery batteries; supplied 15,000 men with a new wagon train, and mounted most of the general officers and started them, a well­ equipped movable column in pursuit. And so the campaign and siege are over, and the administration is blamed by the Copperheads and applauded by all true loyal citizens for turning back the tide of rebel invasion, and this without getting a single man from Maryland, supine Pennsylvania, or from the Governor of New York. Some of the men called out when the danger was pressing, are · beginning to arrive, now that it is over. M. C.MEIGS, Brevet Major-General, U.S. Army. ORA, I, 37, Part 1 (serial 70), 254-60.

Statement of Artificer Nelson A. Fitts, Company B, Ninth New York Heavy Artillery, of the Confederate strength, &c. Sunday morning, July 10, on the left of New Market, while retreating, I was taken prisoner by a squad of the Twentieth Virginia Cavalry, and was taken to the headquarters of that regiment and marched with them to Silver Spring, on Seventh-street road, getting there on Monday the 11th about 3 p.m. The cavalry joined the rest of the command between Rockville and Seventh-street Civil War Defenses of Washington page H-36 Historic Resources Study Part I-Appendix H

road, and I passed the entire length of it; saw their troops and artillery. I also observed some of the inhabitants that gave them information in regard to the forces in Washington, and I could point out the places and men if I were to go back on the same road. On the 12th, about sundown, we left Seventh street in a hurry, marched to Rockville, getting there at daylight on the 13th; halted half an hour, and then went on until 2 p.m., then stopped until dark. We followed the line of telegraph from Rockville to Poolesville, halted on the Maryland side until light (I saw their train and artillery parked), then crossed the Potomac at Edwards Ferry. The prisoners and infantry forded the river and halted, and then their artillery crosse;d. I counted forty­ two pieces as they crossed. They had told me that they had sixty pieces, and I counted them to find out. The colonel of the Twentieth Virginia Cavalry told me that their force at Monocacy was 50,000, and judging from what I saw of the troops myself! should think their whole force was between 40,000 and 50,000. There was Ewell's corps, commanded by Early and Breckinridge, also a part of A. P. Hill's corps that went to Baltimore. After crossing the Potomac the prisoners left the troops and marched toward Leesburg, halting about three miles this side on the 14th about 2 p.m.; staid there until the 16th at 1 a.m. Whilst there, they were attacked in the rear; I could hear the artillery. We left on the 16th and marched to Upperville; halted there until dark, then started to cross the mountains at Ashby's Gap, and there I made my escape to the mountains and staid on the mountain forty-two hours, and then left and joined our cavalry at Bloomfield on the 19th. By being with them and talking with them I have reason to believe their troops were old ones and well disciplined. They had with their artillery caissons to each piece, and an ammunition train. They claimed the object of their raid was to get horses and provisions, that they did not expect to take Washington and hold it, but thought they could raid through the city and capture the President, if there, and draw Grant's forces from Petersburg. They told me they were going to Winchester and then back to Maryland and Pennsylvania. I think that their whole force crossed at Edwards Ferry. They crossed the mountain at Snicker's Gap, all but the prisoners and beef-cattle and eight pieces of artillery, and I should judge about 300 cavalry with fifty or sixty wagons marked "ordnance" and loaded with hay. These crossed at Ashby's Gap. They had between 600 and 700 prisoner:s. So far as I know I am the only man who escaped after we crossed the Potomac.

The within statement of Artificer Fitts is respectfully forwarded to the Adjutant-General of the Anny. I woul9 remark that I have been acquainted with Artificer Fitts for the past year. For some time before his regiment joined the Army of the Potomac he was detailed on account of his intelligence and mechanical skill to act as foreman of carpenters on the defensive works north of the Potomac, and in this capacity he was thrown under my observation. I think the most Civil War Defenses· of Washington pageH-37 Historic Resources Study Part 1-'Appendix H

implicit confidence may be placed in his statements. His estimate of the enemy's numbers may, perhaps, be received with a grain of allowance, but of the forty-two pieces of artillery at Edwards Ferry I have no doubt, a fact which it may be well to know. Should any investigation into the conduct of the citizens of Maryland residing on the roads over which the enemy marched during his late incursion be made, Artificer Fitts might be a useful witness in certain cases.

HEADQUARTERS OF THE ARMY, July 27, 1864. Major-General AUGUR: In addition to the batteries of field artillery which should be kept in readiness to move on the threat~ned point, I think it will be well to place in the forts some field pieces with ammunition, to bear upon the approaches when the enemy comes within short range. These guns can be worked by the same men who work the large guns, as both will not be equally effective at the same time. Consult General De Russy and Colonels Alexander and Haskin on this subject, and as to where the guns should be placed. This must not interfere with the organization of field batteries for use here or in the field. H. W. HALLECK, Major-General and Chief of Staff. [lndorsement.]

On Rock Creek and in front of Fort De Russy, and from Fort Slocum east to Fort Lincoln the brush is not cleared. A great amount of work remains to be done on that line. On account of the limited number of troops in this command it has been impossible to complete the work, although all my available force has been engaged on it.

I HDQRS. DEPT. OF WASHINGTON, 22DARMYCORPS, Washington, D.C., July 29, 1864. Maj. Gen. H. W. HALLECK, Chief of Staff, &c.:

SIR: In compliance with your instructions of the 27th instant, I called together yesterday • General De Russy, General Hardin, Lieutenant-Colonel Haskin, and Lieutenant-Colonel Alexander, for the purpose of consultation as to what additional armament of field pieces it may be desirable to place in the forts defending the city. We find that the armament of these works was settled by a board of officers convened for that purpose by orders from the Secretary of War, dated November 9, 1863.(*) The works have been arranged in accordance with the report of this board, and to make any material changes in the arm_ament would require changes in the platforms or embrasures, involving considerable work, and be likely to produce confusion in the ammunition, besides introducing to the garrisons pieces with whose ranges they would be unacquainted. For these reasons we do not think it will be judicious to disturb the armament of the works at the present time, nor do I suppose that such was your intention in calling my attention to the fact that it might be well to place.in the forts some additional field pieces, it being understood, however, that these pieces are to be used in almost every case in the exterior batteries to the right and left of the forts. It is true that some of the forts, particularly Fort Reno, ought to have some additional field gun~ for use in the fort, when the enemy approaches within short range, but the theory upon which the defense line is arranged is that all, or nearly all, the additional guns that may be required in case of an investment, or even an assault, are to be placed in the batteries to the right and left of the forts, all the principal forts being supported and generally flanked on both sides by batteries placed in commanding positions. It has been supposed that these field guns would be brought into the defenses by an army retreating before superior numbers, but from our recent experience we have seen that the enemy may succeed in appearing before our works before this additional artillery, or even the troops, can get here. Such being the case, it may be well to inquire whether some of the more important batteries on the line of defense ought not to be armed at once, or field pieces, with ammunition, placed in the forts ready to arm them, and hold the -enemy iri check, for some days, at least, in order to give time to re-enforce the garrison of the city. Having the officers whom I have mentioned to advise.me, I thought it well to look into the whole subject in order that we might have an understanding, :and put on record what additional field guns it will be well to have on hand, and where they should be placed on the approach of the enemy at any future time. The following is the result of the consultation on this subject: LINE NORTH OF THE CITY. Fort Sumner.-To have additional field pieces; two to be placed on the line of the conduit to hold the bank between Fort Sumner and the river; two in Battery Benson, on Powder Mill Branch, and two in Fort Sumner, or Battery Alexander, as may be required. Fort Simmons.-Six field pieces to be added; two to be placed in Battery Bailey, on Powder Mill Branch; two in Battery Mansfield, and two held in reserve, or placed in the batteries between Fort Simmon.s and Fort Bayard. Civil War Defenses of Washington page H-40 Historic Resources Study Part i-Appendix H

Fort Reno.-Should have four additional field pieces to complete the armament. Incas~ of attack two or three light batteries should at once be sent to this important post, talcing position at first on the ridge between Tennallytown and Fort Gaines. Battery Rossell.-Being an inclosed work with a magazine, and occupying an important position on the right of Fort Reno, should be armed with two field howitzers, 24 or 32 pounders, and four 12-pounder field guns. Fort Keamy.-There should be four light field guns added to this fort to arm Battery Terrill. Battery Smead.-There should be four field pieces added to this work; two of them to be placed in the battery on the left near Broad Branch. Fort De Russy.-There shol!ld be six light pieces added to this work, to be placed in Battery Kingsbury, and in a battery now under construction, overlooking the bridge on Rock Creek. Fort Stevens.-In case of threatened attack there should be two field batteries here (twelve pieces), one of them to be a mounted battery. These pieces are to arm the batteries between Rock Creek and Piney Branch, including Battery Sill. Fort Slocum.-There should be six field pieces sent to this fort, to arm the batteries on the right and left of the fort. · Fort Totten.-The fort itself is sufficiently armed. The four light pieces are to arm the battery on the left. There ought to be two additional pieces to arm the battery on the right. Fort Slemmer.-Four field guns are required to arm the batteries on the right and left. Fort Bunker Hill.-There should be eight light pieces added to the armament of this work for the battery in front, and the batteries on the right and left. Fort Saratoga.-There should be six light pieces added to this fort, to arm the batteries on the right and left. The new redoubt (not named) between Fort Saratoga and Fort Thayer should be armed with four field pieces. Fort Thayer ought to have four field pieces to arm the batteries between it and the railroad. Fort Lincoln ought to have six additional field guns to arm the exterior batteries, beginning on the left at the railroad and ending on the right at Battery Jameson, on the Eastern Branch, malcing for the line north of the· city, eighty-eight additional field guns. Over the Eastern Branch.-The board to which allusion has been made had substituted field pieces for many of the barbette guns with which these forts had first been armed, and they are generally well supplied with small guns. Since that time, however, Fort Foote has been completed, and extensive additions have been made to Forts Stanton and Carroll. These being the most important works on this line, it seems proper that they should be sufficiently armed. Fort Foote requires two 24-pounder, flank defense howitzers; one 12-pounder mountain· howitzer, four 12-pounder Napoleons. Fort Stanton requires one 32-pounder howitzer, two 4 1/2-inch rifled guns, four 12-pounder howitzers, two 12-pounder Napoleons. Fort Carroll requires one 32-pounder howitzer, two 30-pounder Parrotts, six 12-pounder howitzers, malcing for the line over the Eastern Branch twenty-five additional pieces. Civil War Defenses of Washington pageH-41 Historic Resources Study Part I-Appendix H

SOUTH OF THE POTOMAC, Forts Marcy and Ethan Allen.-There ought to be six field pieces added to the armament of each of these works, to be used in the adjacent batteries in case of threatened attack. Two additional (mounted) batteries should be sent to this position in case the enemy appears in force. Fort C. F. Smith is sufficiently armed, but in case of a threatened attack the batteries on the north side of the river, flanking this work, should be armed, the north battery with two 10- pounder Parrotts, and the south battery with two Napoleon guns. Fort Craig ought to have four long guns, 30-pounders, or 41/2-inch guns for the batteries on the right and left, and six Napoleon guns for the battery at the Columbia turnpike and the adjacent batteries on the right and left. Fort Barnard requires two 12-pounder Napoleons for the exterior battery. Fort Ward.-There should be added to this work twelve light guns. Four to guard the Leesburg turnpike north. of the fort, and the remainder for the batteries toward Fort Worth.' Fort Williams ought to have eight additional light pieces to arm the batteries, two on the right and two on the left. Fort Willard requires four additional fieid guns for the adjacent batteries to the right and left of the work. Fort Jackson, at end of Long Bridge, ought to have two light guns, making for the line south of the Potomac fifty-four additional guns, and for all the works around the city 167 additional guns. It is not supposed that all of these guns can now be obtained. I propose, therefore, only to send requisitions for those which seem to be in-dispensable-say field guns. For Fort Reno and Battery Rossell, 10 guns; Fort De Russy, 6 guns; Fort Stevens, 6 guns; Fort Saratoga and the new redoubt, 6 guns; Fort Lincoln, 6 guns; Fort Stanton, 9 guns; Fort Carroll, 9 guns; Fort Foote, 7 guns; Forts Marcy and Ethan Allen, 6 guns: Fort Craig, 6 guns; Fort Ward, 6 guns; Fort Williams, 4 guns; Fort Willard, 2 guns; Fort Jackson, 2 guns; making 75 guns. As the enemy cannot approach the city in all directions at the same time, it is hoped with due watchfulness that we may with the additional field guns now asked for so arm any point of attack as to hold the enemy in check until the city can be re-enforced with the necessary additional troops and batteries. In this conviction I cannot withhold the remark that our works are strong in themselves and strong in their armaments, but forts and cannon, even if Gibraltars, cannot of themselves defend a city against an enemy. In case the enemy attack us we will also require soldiers. [C. C. AUGUR, Major-General, U.S. Volunteers, Commanding.]

OFFICE CHIEF SIGNAL OFFICER, DEPARTMENT OF WASHINGTON, Washington, August I,· 1864. Capt. JOSEPH H. SPENCER, Signal Officer, U.S .. Army: CAPTAIN: I have the honor to make the following report of this detachment's operations for the month of July, 1864: Nothing very important transpired except the ordinary business of the corps until the 10th, when Capt. E. H. Russell and party were ordered to report to me for duty. The enemy had already made their appearance in considerable force in front of Fort Reno, on the Rockville pike, and also in front of Fort Stevens, on the Seventh-street road. I received verbal orders from General Augur to station my officers so that communication could be had with all principal forts on the north of the Potomac. Accordingly, Lieut. P.H. Niles was placed on the Soldiers' Home, from whence he could communicate with all the forts on the line north of Potomac. This station proved to be of much importance, as communication could be held direct from pro­ vost-marshal's building in the city to any of the forts through it. Lieut. Asa T. Abbott was stationed at Fort Stevens; Sergeant Kintner at Fort Slocum, and Corpl. William Wallace at Fort De Russy. Later in the day Lieut. R. P. Strong reported for duty, in obedience to orders from office signal officer, and was ordered to Fort Totten. Sergt. H. A. Sofield was taken from Fort Smith and put in charge of station at Fort Bunker Hill. Capt. Thomas J. Sawyer reported on the 11th, in obedience to orders from signal office, and was sent to open a station at Fort Lincoln, so that with Sergeant Richards at Fort Sumner and Captain Dillingham at Fort Reno the line was complete from the Potomac to the Eastern Branch. On the 12th Lieuts. F. S. Benson and E. H. Wardwell reported from Baltimore, and were placed in charge of the stations at Forts Slocum and De Russy, which were in charge of Sergeant Kintner and Corporal Wallace. During the 10th, 11th, and 12th the officers were continually engaged in sending messages of an important character. On the 14th Colonel Haskin applied for an officer to be placed at Fort Marcy, Va.; accordingly Corporal Wallace was taken from Fort De Russy and ordered to Fort Marcy. On the 16th, by request of Major-General Doubleday, General Augur directed me to send an officer to Fort Baker, D.C. I accordingly sent Lie.utenant Benson from Fort Slocum, and Lieutenant Strong was ordered from Fort Totten to Fort Slocum, the latter fort being farthest in advance and more important. On the 20th Lieutenant Strong was ordered to Fort Reno and Captain Dillingham to Fort Slocum. This change was thought proper, as Lieutenant Strong had recruiting papers at Signal Camp that needed his attention. On the 21st Captain Russell and Lieut. A. T. Abbott were directed to resume their Civil War Defenses of Washington pageH-46 Historic Resources Study Part I-Appendix H

duties at Signal Camp, the exigency having passed, and their services were not needed in the field as much as in camp. The· officers and men were prompt in the discharge of their duties, and I take pleasure in recommending to your notice Lieut. Asa T. Abbott, whose station was continually under the enemy's fire, and who many times narrowly escaped being struck by the enemy's bullets, but maintained his position and continued to work his station, under fire, for nearly two days. * * * * * * * . * * * The health of the detachment is very good.

SOLDIERS' CEMETERIES. Careful records of the burials of soldiers in the cemeteries in the neighborhood of Washington have been kept. The grounds near the Soldiers' Home, north of the city, having been filled by the burial of nearly 8,000 persons, by your direction a portion of the Arlington estate has been appropriated as a national cemetery. The grounds have been carefully surveyed and suitably laid out and inclosed. Already nearly 3,000 interments have taken place in this national cemetery. The graves are carefully sodded, and at the head of each is planted a neat headboard, painted white, on which are inscribed in black letters (the number referring to the burial record) the name of the soldier, his company and regiment, and the date of his death. I transmit herewith an extract from the report of Capt. James M. Moore, assistant quartermaster, who has, during the greater part of the fiscal year, had charge of interments of soldiers dying in Washington. The bodies of the loyal officers and soldiers who fell in the sortie from the defenses of Washington, which drove off the rebel army in July last, have been buried in a piece of ground selected for the purpose in the midst of the battle-field and in sight of Fort Stevens. It is hoped that Congress may see .fit to cause a monument to be erected to the memory of these patriots who fell in the defense of the capital itself. In other cities around which hospitals are collected, under general orders and regulations, careful records of burials are kept, which should ultimately be transmitted to Washington and there preserved for future reference.
