However, it should not be assumed that when the Ger- mans are thrown on the defensive, they will not know what to do; the Libyan campaigns are evidence to the contrary. At certain periods in this campaign, the Germans had to take a defensive role and develop defensive techniques in a terrain and type of warfare entirely different from those in other theaters. They showed ability to adapt the old principles of defense to these conditions, and this resourcefulness may be expected in the future. It will take imagination, thorough preparation, and careful reconnaissance to deal with the defensive tactics that may be expected from the Germany Army. 4 ·i r i O ms2'3 w m 5 L::: c··: c·P,'-r.·. ::I;:·"-'i niil ; Hs·: S I ·.. :· -.ln..?i·ii"iii: :"'.'?Yfi.i:,.·i·;·- vL1 t cr, ;·::'.·'·I· i::;'':·':·:i:l-·· ·· 'n .E :, ;·:.:··.:· ?i :· ..=.··· O C31 I :·I· m,· Q "· m ;c: 1'··" Section I. INTRODUCTION The German force that was concentrated in Libya dur- ing February and March 1941 was indoctrinated with a zeal for the offensive. This spirit was founded both on an aggressive national philosophy and on a body of tactical doctrine that emphasized the importance of achieving and maintaining the initiative. Officers had been taught that attack and its exploitation were the keys to success in battle. In their service schools they had solved ten offensive problems for every defensive one. While one German training manual did set forth in detail the organization of the defense, this lesson had not been mastered. But the Germans were to face a new problem in North Africa, where supply by sea and desert logistics largely condition tactics. When they failed to take Tobruk in early April 1941 and were again repulsed on May 1, Marshal Rolmmel's Afrika Korps 1 found itself for the first tine seriously on the defensive. I The German Afrika Korps comprised the 15th and 21st Armored Divisionls and the 90th Light Motorized Division. They were made up approximately as follows: 15th Armored Division--8th Tank Regiment, 115th Motorized Infantry Regiment (?), 33d Artillery Regiment, 15th Motorcycle Battalion, 33d Motorized AA/AT Battalion, and services. 21st Armored Division-5th Tank Regiment, 104th Motorized Infantry Regiment, 115th Artillery Regiment, 3d Motorized Reconnaissance Battalion, 39th AT Battalion, 200th Engineer Battalion, and services. 90th Light Motorized Division---155th Infantry Regiment, 361st Infantry Regiment, 361st Artillery Battalion, 190th Engineer Battalion, 190th AT Battalion, and services. 2 GERMAN DEFENSIVE TACTICS IN CYRENAICA-1941 With characteristic German adaptability, commanders devoted themselves to learning the technique of position warfare. While doing this, however, they did not forget their maxim that "The object of the defense is to wear down an attack before launching a counterattack." Led by Rommel and his staff, many lower commanders made important contributions during this experimental period. The story of the development of German defensive tactics, with its new theories, successes, and failures, has been pieced together from captured German documents. This account is valuable both because it gives an inside view of the enemy defensive system and because it demonstrates the ability of the German Army to learn from experience. The three maps included in this bulletin were drawn by the Military Intelligence Service, and defensive posi- tions indicated on them are of necessity only approximate. Map No. 1 is included for the purpose of orienting the reader in the North African theater; map No. 2 shows the German front line defenses on the frontier as of November 1941; map No. 3 is included to allow the reader to follow developments in the Gazala-Tobruk sector. Figures are schematic representations of German defensive positions. Section II. NEW DEFENSE PLANS, MAY 7-JUNE 15, 1941 1. ORIGINAL DOCTRINE A sound defensive system existed in the German Army prior to the Libyan campaign, but it had to be expanded and altered to meet special conditions existing in the desert. The German doctrine of defense, which formed the basis of the system developed in Libya, may be summarized as follows: (1) Effective fire is more important than cover. (2) The object of the defense is to wear down an attack before launching a counterattack, generally with armored troops. (3) Reconnaissance must be made to discover enemy intentions and to screen one's own positions, which are organized in depth. (4) A linked fire plan must cover the entire front. (5) Most of the fire should be concentrated to cover the stiitzpunkt 2 which is the key to the position and the 2 Militdrisches Wmrterbuch, a German dictionary of military terms, defines Stiitzpunkt as "A strongly constructed and armed point in a defensive position which is capable of being defended when the enemy has forced his way into the defensive position and is able to attack the position from the flanks of the break-through. One must be careful that the staitzpunkt is well camouflaged in order that it may not be prematurely recognized and neutralized by fire." Because of the difficulty of giving an exact and concise translation of ,Statzpunkt in U.S. tactical language, the German word is used throughout this bulletin. 3 494596:--4 2-....2 4 GERMAN DEFENSIVE TACTICS IN CYRENAICA-1941 objective toward which the enemy is likely to put forth his main effort. (6) A series of mutually supporting centers, each capable of all-around defense, must be organized in depth. For the defense, troops are disposed in three main positions: (1) Vorgeschobene Stellungen, or advanced positions. (2) Gefechtsvorposten, or battle outposts. (3) Hauptkampflinie, or chief battle line, corresponding to the U.S. main line of resistance. This main defensive position is designed to be held until the counterattack. In a paper written in early June 1941, a German major lamented the fact that "Our people know next to nothing about the construction of defenses. We have scarcely any exercise in this phase of warfare in our peacetime training. The junior commander does not realize that positional infantry warfare is 60 percent with the spade, 30 percent with the field glasses, and only 10 percent with the gun." In the same paper the major indicates his belief in the superiority of British camouflage and deception.
