III. HISTORICAL FACES RELATING K) PHE SUBJECT . Reasons for the Battle *

During 1917 , until the Battle of Cambrai , while the tank enthusiasts were trying to develop their weapon and arrange for its use as they felt it •ho-.ild be employed , the theory of the annihilating preliminary artillery bambardusat controlled &11 attacks (l) . Surprise , particularly strategical surprise , was forfeited (8) .The long artillery preparation made the tone of advance almost impassable for artillery and transport (3) and that demanded a limited objootive (4) No exploitation was bailed for (5) .

At that time the rank Corps was still on probation (8), Within British GHQ, in franco there was opposition to any further Increase in tarfc produotlon » particularly after their failure at the Phlrd Battle of Tpres (9) , But the Panic Corps felt great oonflCenoa In this new weapon and was anxious to increase the number of machine a available for use in France , and to use them as thejr felt tanks should be employed (10) .I f they were to suooeeed in this , i t was first necessary to convince the authorities of the power and value of the tanlc (IX) , A big tank battle had for a long time been in tttt thoughts of the leader* of the Pank Corps (13) . the original plan for the tank battle at Cambrai was conceived by the Panic Corps which was also largely responsible ",r putting through the plan (13) • Lt.Col.J.T.C.Puller , Chief General Staff Officer of the Corps , states that the general area around Cambrai was seleoted by them as early &s II June 1917 (14) . Phe original plan of the Pank Corps called for a surprise raid , on a large soale , lasting about 24 hour's . PhA object was to be the destruction of the enemy's personnel and guns , the dencoraliaation and disorganisation of his fighting troops and reserves and nc>t the capture of ground . Phe plan

of the plan (17) , Undoubtedly he' very soon afterwards approached British iotober , did approve the project and the data of attack was set for 20 November (19) , Oat i • • considerasion whioh influenced Field Marshall Sir Douglas Valg in his approval of the attack was that the recent Hussian collapse had already set fret large forces of German troops from the Fast and others would probably very soon bo available on the Western Front , making an Allied attaok there acre difficult (20) » Another faotor which nntt have influence A hi* to some extent was thai the 1'prec offensive , stil l continuing , was certainly not a success and any Brisilflh success would be something of an antidote (21) , British forces , The forces allofctd to General Byng for thii battle wero two corpe of

It ran generally ; within the sone of the main attack , from Creveooeur through the, northern edge of Maenleres and just south of Bourlon (See Map Ho2)» The outpost was well wired as was most of the support line and part of the third line . Che main line of resistance was oovered in , front by a dense belt of bar'ed wire entanglements , really three broad belts separated by narrower irregular lanes .In many sections these entanglements were pushed out even farther to the front to form salients , well oovered by machine guns (43) , British officers felt that never before had they encountered such terrific barbed wire entanglements (44) .th e German trenches were constructed with a view to preventing possible crossing by tanks and were , consequently , very wide and deep , in many places as wide as 16-16 feet (45). Tha British Tank could not cross a trench vrid*r than 10-11 feet (46) , for

Jbi most part ; these trenches wsre on the reverse slopes of t» * main ridges and consequently direct artillery observation upon them , from the British area , was iimpossible (47) » While this position of the.

- 6 ­ General Plan fftr the At back «

The plan for the Carabrai attack t tBtfS^f approved by British OHQ , was quite different from the original plan of the Tank Corpe • The main attack wae bo be made b|t the Third Army , reinforced at explained under "British Forces" above , in the area between the Canal de L'Zscaut on the east and the Canal du Word on the west k At the same hour demonsbrabions wiA gas and smoke and ar tiilery were to b* oarried out along praebibally bhe entire British front with subsidiary or dummy attacks east of Epehy on bhe right and between Bulleoourt and Fontaine-les-Croislllies on the left • Seorecy was held to be vital in order to secure surprise . There was to be no artillery preparation . The tanks were to be responsible for tearing gaps in the German wire ­ entanglements as well as for covering the advance of the infantry by protecting it from hostile machine gun fire (52/ . The artillery was bo asalit wibh oounterbabbery and barrage fire , by putting down smoke screens , particularly along the right flank of the III Corpe , fcnd by speoial concentrations on prearranged localities suoh as benbers of couraunioation and roads likely to be used by the German reserves (53) ,111 three of the German defensive systems were bo be penetrabed on bhe first day , the taiks and infantry working in oloae cooperation . If this break-through wove successful , the high ground around Bonrlon was to be secured and a flank position established ta the eastfitowards Cam^rai , Tiha oavalry wai to pass through for looal exploitation between Bourlon and bhe Sesee River to the northwest and r»ld the German coEorunicablons , damage their railatftAe and intorfere with the arrival of their reinforcements . Tao capture of Cambrai Iteelf was not planned •

It was believed that no large German reinforcements could reach the soeno of this action /or 48 hours . Che Comaander-in-Chief reserved the right to stop the attack at the end of 48 hours , or sooner , unless

A total of 39 tanks were to be set aside inraidiately for this purpose ,(67) , Tank Tactical Organisation and Allotment , The let Tank Brigade consisted of three battalions , D,K and 0 , eaoh normally with 42 tanks but 0 battalion had sore machines from each of the oilier battalions , giving it a total of 60 , Tht 24 Tank Brigade, had one battalion detached for this attartc and consisted Men of two battalions , B and H , eaoh with 42 tanks .

Detailed Tank Plan ,A careful plm of coordination for the tanks was hsotdsary because there were three broad trenches to be orossed , each tank could carry only one fasoine , and onoe that had been dropped into a trench there was no means of recovering It (70). Each tank section was to consist of three machines , one Advance Ouari Tank and two Infantry (or Main Body) tanks (?ft), Phe advanue guard tank was to precede the others by about 100 yards , and the interval between mala body tanks was to be about 100 yards (72). 3aoh objective was divided Into tank seotlon attack areas according to the number of tactical points In the objective . A separate eohelon of tarfcs was to be alloced to each objective (73}, Che Advance Ouard tank was to go straight forward through the enemy's wire , and , turning to the left (without crossing) move along the trench .

Colonel Fuller states that steps were taken to reconnoiter the Caubrai area even before the battle was sanctioned (97) , Inasmuch at , in the beginning , only four members of the Staff of the Tank Corp* knew of the approaching attack , sihoe no additional airplane reoonnaissanos • was permitted,, an4 as secrecy wa* so important , there was a limit to

the amount of reconnaissance of the German position and of the terrain under German control . In spite of these handicaps there were , we are informed by a tank brigade commander , hundreds of airp?.ane photographs taken , masses of material collected , and every source of information tapped (98) , While lank Corps reconnaissance wae started as early at secrecy would permit , it was not until a .few days before 20 November that * tank oorrmanders were permitted to reconnoiter the ground from the British front-line trench system (99) » The watercourse marked on all maps as "Le Grand Savin" und feared as an obstacle was found from & study of airplane photographs to be nottii;ig alarming (100) . One fact of gre,fc, importance was however determined , namely that the German trenches were very broad , as wide In places as 16-16 feet , a broader span than any t&rk could then cross unaided (JOl) , Forward assembly positions for the tanks were selected ana the route of each tank from

Concentration in Training Areas .

On October 20 , tanks were eoafctered over a wide area . Th» 1st Brigade was in the Ypres Salient , another brigade was at Lens Tort , and the other at Benaicourt (103) • The reasons for concentrating the tanks at training areas are given under "Cooperative Training" , 'below , A tank company coniaander in the 1st Brigade informs us that that brigade received preliminary orders , late in October and final orders about the 1st of November to move to Wallly near Arras ,(just outside the village of Blviere)(lO4) , The entire Tank Corps , consisting of three brigades of three battalions •aoh ,-mor* than 400 machines with gun carriers and supply tanks - was concentrated in training Areas early In November (105) •

Cooperative Training .

It was felt that the whole Tank Corps must be concentrated at training areas so as to make possible cooperative training with the Infantry . Phis was considered to be very lraptrtanb , not only beoaute of the necessity for developing combined aotion , but chiefly because success dependsd so ouoh upon developing the confidence of the infantry in tanks (106) .Only a short time , about a week , was available for this training and it was therefore impossible for rooro than a small

A compltt© tyt^m of Unk and Infantry cooperation was worked out by L t.

These taotios are given in detail •under "Some Details of the Plan" above , Every effort was made by tb© Tank Corps to develop the confidence of the Infantry in this new weapon . fhe infantry was called upon to construct their own defenses and nir* entanglements , making them as strong as possible .The tanks were abray* able to push through without Kuoh difficulty (109) «

The movement forward from concentration point required four nights and was postponed as late as praotioablo « 27 train loads were concentrated at Plateau Station by 14 November « These trains were sent forward to detraining areas on the nights 16*17 17*18 and 18-19 November .

Almost every machine was at least partly torn down , being refitted , or with its engine undergoing repairs .There were none readym for action .

December (201) , Through faulty distribution of orders the tank units in that area ware late in learning of the plan to withdraw . Numbers of the machine a were dismantled for repairs and could hot be reassembled in time to pul). out , Many tanks , therefore , had to be abandoned (202) . There was no further fighting , in that battle , for the lank Corps . A tank officer states tkat the 2d and 3d Brigades were then withdrawn to winter quarters at Bray and that the 1st Brigade remained flor about two weeks in a defensive position in Dessart Wood and was then withdrawn to the rear (203) .

ANALYSIS AMD CRITICISM «

The original intention of the rank Corps in planning an attack in the Caribrai seotor was evidently to put on a demonstration to show the power of tarka under favorable conditions , in the hope that thin would prove to the British military authorities their value and mate* possible an increase in the site of that branch (204)« Pro par provision was made , in the OHO. plan , to stop the attack

if" it were not progressing satisfaotdrily (205) • it is believed # however , that proper provision was not made for the exploitation which was contemplated , in that the troops alloted to the Third Army wert not sufficient to carry out the entire plan (206) , It it believed that

- 29 ­ the Third Army plan was defeotive because ii put all of Its infantry and tank strength into the assault , leaving no general reaerve of either (207) . Oru* historical account states that it was against expert adrice that all of the tanks were put in the assault , aid spread out over the entire froat (208) tut no statentnts are found in the accounts written* by tank officers which show that they had , at that tiae , any idea of holding out a reserve .It would appear that they** accepted the final plftn without reservations and thought that they had at ljfast been given frhe opportunity for whioh they had waited so long (209) . The preparations for the employment of the tartcs * were particularly thorough (210) and were carried out without the knowledge of the Oernans (2Il) • Weather conditions , for some days preceding the ati*ck,were particularly favorable to the British (212) but the maintenance of seoreoy evan with that assistance was in itself a remarkable tohievetosnt • Sonoe of the detraining points were within G kilometers of the German lines (see Map No.3) practically within the range of any 3" guns , inVa position well forward and well within the possible range of larger calibre* .

They must certainly have be^n within the range of most of the forward German guns , Phe maximum speed for the tanks was only 3.7 miles per hour (115) bub even with that speed the assembly areas could have been much farther to the rear and stil l have 'permitted the tanks to reach the line of departure during the twelve hours or more of darkness (216) . The storage of all tank supplies at the actual assembly areas is considered to be a disadvantage . Not only were they within German artillery range but the accuiailation of such a large mass of supplies so close to the front necessarily made the concealment of the assembly areas that ttuoh more difficult . AUplane observation at that time was , of ocurse , much less effective than now but Che heavy fogs which practically prevented German observation during the period of this forward movement and assembly were probably of greater assistance to the British than even they realised at the tin* .

The ground over which the i.bttck was made was favorable for the action of tarka (217)

The British attack was a strategical surprise because no attack in that area was even suspected by the Germans until it was Just about ready |m jump off (218) . <)n 16 November the Gerian Saoond Army announced that no major offensive along their front was indicated , that no prepararions had been discovered (219) , On Id November a German

Farther , the Germans knew that their trenches were vider than the span of the British tanks and felt secure from a successful penetration (223) , Phe initial success of the British was due almost altogether to this surprise attack of the tanks , and tanks alone made this surprise possible (224) • Tanks demonstrated their ability easily to clear passages through the toughest of wire-entanglements , thus to a great extent taking over the mission of the preparatory »rtillery bombardment (225)« With a long preparation surprise would hare bean lost • A tremendous saving of a/munition «Aee resulted also fro-a this substitution . It was estirated that It would have required several weeks bombardment and scores of thousands of tons of ammunition to have cut adequate gaps in this wire b} artillery fire (226) ,

The detrimental effect upon the morale of the {toman troops caused by the »ase with which the tank3 pushed through the heavy , broad , wire entanglements and over the wide , deep trenches and by the impotence of the Infantry against these machines was very great • It Is safe to say that the panic within the German position on the

Tanks were shown to be particularly valuable to artillery fir** When struck by direct hits they were destroyed or at least put opt oi action (233) . On 20 November no less than 16 tanks were knocked out by one field gun (233) « tanks wer*Lsuccessful in pushing through Flesquieret on 20 November because of the stout wall around the chateau (234) « On the other hand when they were able to go around a villas* and threaten it from the flanks and rear they were more successful , as at Havrinoourt on 20 November (236) •

- 33 ­ If the infantry of the 51 it Division had been following In close support of the tanks in the attack against Flesquleree on 20 November i t seems safe to conclude that the heavy tank losses would not have oocared , Ihey followed too far in rear and there was apparently a lack of cooperation between tanks and infantry (23?) . A few riflenren , working ahead to the crest eouth of Flesquleree should have Veen able to pick off the German gunner and thus enable the tajiks to advance without being engaged by a field-gun at short range (238) , Late in the day , 20 November , the tanks pushed son* distance ahead of the exhausted Infantry but , being unsupported , were forced to withdraw (239) , Some dosage was done by the tanks to German wire conriunications (240) but evidently that was incidental , Accounts by cank officers do not indicate that such a mission was given to any tanks . OapB in the wire entanglements were cade for the oavalry as planned (241) . Consideration of the reasons why the oavalry was not sent through for exploitalon , then or later , is outside the ecope of this study , The olose of the first day's fighting , 20 Novenfcer , left tbt British in control of the Geroan position to a depth of about five miles , at the point of greatest penetration (242) , Over 100 German guns and somewhere between 5000 and 8000 prisoners had been captured (243) .

Phe Connander-in-Chief, in fels estimate of the situation at the close of fighting on 21 November , emphasised the great importance of the contending terrain - Bourlon Ridge (See page 25 above) , It eeeme reasonable to conclude that with sonre reserves of infantry and tanks this position might easily have been captured on the first day of fighting ,

Tank casualties on the first day of the attack were heavy , possibly as great as one-half the total number in action (248) . On 21 November the tanks employed were foraed into composite companies ) they operated for the most part with new (Vat not fresh) infantry units , There was apparently eone lack of cooperation between the two branches (249) . As on the preceding day tanks pushed well forward of the tired Infantry but , unsupported , were forced to wlthdra*r(26C), German reinforcements had been rushed to threatened points and on 21 November their resistance stiffened (251) .

It had been thought, prior to this battle , that if the tanks broke through the main trench systems and the infantry went on through the latter would be able to advance , in the mobile warfare beyond , without the assistance of tanks , Since there was no real break-through with adequate forces , In this battle , no test of this theory was possible but such troops as did paes through were held up quite easily by machine-guns that had been rushed to these gaps (257). , One British officer states that he observed the advance of 21 November from a good OP on Fles^uieres Ridge .I n describing the cooperative action of tanks and infantry he states that when the German machine-guns opened fire , the infantry took cover • Phe tanks then hunted out the maohine­ guns whloh ceased fire when the tanks earae near them , Phe infantry was then able to advance , even before the noaohine-guns had been destroyed (258) ,

Since BourIon Ridge was the decisive terrain feature (266) and since a good approach for tanks existed along the ridge fro^ Havrlncourt north to BourIon Ridge (8ee Map ffo.2) , the tank effort should have been concetrated on the west flank , It was undesirable to etcploy any ta-fce east of the general line Tillers - Pleuich - Marcoing because tb«y would have to operate In a email pooket and would run up against the unfordable Canal de L'Eeoaut within 4500-8000 yards of the line of departure .

In open ground the tanks Dad* the advance of the Infantry comparatively easy . Hot only did they clear passages in the wire entanglements but they also put out the oaehine­ cunt which were endangering the Infantry advance , Where the infantry followed closely enough so that the hostile machine-gunners ware unable to get into action again after the tanfcs had passed , the combination was very, successful , This system was used along crost of the front , and illustrates the principle of cooperation . In the few cases where the •Infantry followed at such a distance that the eneoy machine-gunrars were able to get into action after the tarfes had paesed over and before the infantry arrived , the advance was checked . Close cooperation between Infantry and tanks le therefore essential for the ocn*.u«l protection of the ewo branches . Combir-sd training is a great assistance in obtaining this cooperation , All of the tanks employed by the British were slow tanks . Where they pushed forward , well aheal of the infantry , they were finally forced to withirnr , rank* catnot hold ground . Blow tanks are incapable of indeptndent action for long periods . Ihey ehould therefore be ettployed chiefly as an auxiliary to the lnfarr.ry . - 41 ­ Tanks are not well sullied for employment within stone villages. Finks suffered heavy casualties from artillery fire ; they are r-arfciculijrly vulnerable to such fire . Counterbattery missions of friendly artillery are a vital neocesalty in assisting the advance of tanks , particularly of tanks which mat move slowly within restricted areas as did all of the tanks on the first day of tho battle .(This was due partly to the fact that they were incapable of rooving rapidly and partly to the fact that they were all used as accompanying tarks )• Some confusion resulted within the German position through the disruption of tfire comaunications whioh were incidentally destroyed , Sons talks should have the mission of destroying hostile wire co
