of Bessarabia, Odessa, and the Crimea.
2. The Main Effort. The main effort was to lead to the destruction of the Russian forces west of Moscow by a direct thrust on the capital. Once in possession of Moscow and northern Russia, elements of the main-attack force would turn south and seize the Ukraine in conjunction with the southern groups.
The principal attack would have to be directed from East Prussia and the northern part of Poland toward Moscow because no decisive operation could be launched from Romania and an initial sweep toward Leningrad would only lengthen the distance to be covered and lead into the dense forests northwest of Moscow.
During the advance on Moscow the left flank would be protected by a special force that was to be committed across the Dvina River toward Pskov and Leningrad. After capturing the latter important industrial city this force might operate in conjunction with the main-attack force.
The road and rail nets west of the Russian border were capable of supporting the advance on Moscow. The terrain that had to be crossed by the forces jumping off from East Prussia was difficult. They would have to traverse a forest and lake belt between the Dvina and Dnepr. There, the battle for the traffic arteries would be decisive. Airborne troops would have to take possession of the eastern exits from large forest areas and thus keep the roads open.
3. Movements. Since surprise and speed were of the essence, armored and motorized infantry forces supported by tactical air power were to break through the enemy lines, with ordinary infantry divisions following closely to encircle and destroy the isolated enemy forces. The strength of the first attack wave was limited by the relatively small number of through roads. At most, two division-size units could advance abreast on any one road. The bulk of the infantry with its horse-drawn vehicles would have to march on such side roads as were available. As a result, all units would have to be deployed in great depth. The enormous width of the funnel-shaped theater necessitated keeping strong motorized forces in reserve and so distributing them that they could easily be shifted within the theater.
g. Distribution of German Forces.
h. Primary Missions of the Ground Forces. The primary mission of Army Group South was to destroy the Russians in the western Ukraine and to establish bridgeheads across the Dnepr from which the army group forces could continue eastward or northeastward.
Army Group North was to seize Moscow. To accomplish this, motorized units would have to drive through the forest areas between Rogachev and Vitebsk with airborne troops assisting them at the forest edges. If the Russians chose to make a stand between the jump-off line and the forests or the Dvina, they would have to be pushed northward, away from the direct route to Moscow. While the reduction of these enemy forces was under way, the armored and motorized units were to move on until they reached the Russian capital.
i. The Mission of the Air Force. The Luftwaffe was to neutralize the Soviet Air Force, disrupt rail and road communications, prevent the concentration of Russian ground forces in the forests areas, support the German spearhead units with dive-bomber attacks, prepare airborne operations, and secure the air above traffic bottlenecks.
j. The Mission of the Navy. The Navy was to neutralize the Russian fleet in the Baltic, safeguard the iron ore shipments from Sweden, and transport supplies across the Baltic as soon as the Army had seized the ports.
k. Logistics. A special staff was to be formed to coordinate supply problems and establish bases behind the two army groups. It was anticipated that the Russians would attempt to carry out large-scale demolitions and destroy supply dumps, rail lines, and bridges. This could be partially prevented by keeping them off balance and by preparing appropriate countermeasures. In the Ukraine, Lithuania, and Latvia agents might be able to seize bridges and railroad installations and thus prevent their destruction. All railroad tracks beyond the former Polish border would have to be converted from the Russian wide to normal gauge.
A military administration would have to be set up for the occupied areas. In the Baltic States, White Russia, and the Ukraine the military government agencies would have to work toward turning their authority over to autonomous, non-Communist local governments.
l. Time Phasing. The most favorable season for the campaign was from mid-May to mid-October. After a mild winter, it might be possible to start as early as the beginning of May.
It was anticipated that all units needed for the initial operations would be assembled before the outbreak of hostilities. In the event of an unexpected outbreak of fighting, the forces scheduled to be assembled in the Army Group North area would need approximately 10 days to arrive in their designated areas and those in the south 9 days.
During the initial phase of the German offensive the Russians would probably fight delaying actions over distances of up to 250 miles, until they reached their prepared positions. The German infantry divisions would take three weeks to cover this distance. The panzer divisions would have to advance so rapidly and penetrate so deeply that the Russians would be unable to man a continuous defense line. The issue of the entire campaign would depend on the success of the armored thrusts.
The struggle for the forest areas and river courses would dominate the second phase. Since the depth of this zone was 60-120 miles, it would take 2-4 weeks to cross it. At this stage the German forces would either achieve a decisive breakthrough or destroy the previously shattered Russian forces individually.
During the third phase Moscow and Leningrad would have to be seized and the drive into the eastern Ukraine initiated. The distances to be covered were 250 and 200 miles respectively. Whether this phase could be executed immediately after the second would depend upon the condition of the railroads, the serviceability of the track-laying and wheeled vehicles, and the degree of success hitherto achieved. If the Russians were beaten, a few armored or motorized divisions would suffice to keep them off balance, and to seize Moscow and Leningrad and thrust deep into the eastern Ukraine. This would require one or two weeks if sufficient tanks and motor vehicles were available. If, however, the bulk of the Red Army was still capable of offering organized resistance, the start of the third phase would have to be delayed until sufficient supplies were brought up to support the continuation of the offensive. In this case it might be 3-6 weeks, depending on the time needed for the supply buildup.
The fourth and last phase of the offensive would see the Germans pursuing the Russians to the Don, the Volga, and the Severnaya Dvina. The distances to be covered were 250 miles in the south and up to 500 in the center and north. After the Germans had captured Kharkov, Moscow, and Leningrad, the Soviet command would have lost control over its forces but complete occupation of the territory acquired during this phase would be neither possible nor necessary. Motorized forces and rail-transported infantry would be responsible for this operation. The time needed for this phase was estimated at 2-4 weeks.
The total time required to attain the designated objective would therefore vary between a minimum of 9 and a maximum of 17 weeks.
In the event that the Soviet government did not collapse or make peace, the offensive might have to be continued to the Ural Mountains. After the destruction of their armed forces and the loss of their most valuable European territories, the Soviets would probably no longer be capable of conducting military operations but could still set up a government in Asia and maintain a state of war for an indefinite period.
To this plan General Marcks added recommendations for the preparation of the campaign, including details regarding signal communications; the construction and improvement of roads, bridges, railroad facilities, and billeting areas; the organization, equipment, and training of troops; and the procurement of cartographic material.
General Marcks discussed his plan with General der Kavallerie (Lt. Gen.) Ernst Koestring, the German military attaché in Moscow, during the latter's presence at Army High Command headquarters. Koestring did not agree that the seizure of Moscow would be the key to victory. In his opinion the capture of Moscow would not be decisive because the Soviet Union had vast industrial resources beyond the Urals. Moreover, with their ability to improvise, the Russians would be able to reorganize their transportation
