German Panzers One Day Before Barbarossa

The Germans had begun massing troops near the Soviet border even before the campaign in the Balkans had finished. By the third week of February 1941, 680,000 German soldiers were gathered in assembly areas on the Romanian-Soviet border. In preparation for the attack, Hitler moved more than 3.2 million German and about 500,000 Axis soldiers to the Soviet border, launched many aerial surveillance missions over Soviet territory, and stockpiled war materiel in the East. Although the Soviet High Command was alarmed by this, Stalin's belief that the Third Reich was unlikely to attack only two years after signing the Molotov–Ribbentrop Pact resulted in a slow Soviet preparation. This fact aside, the Soviets did not entirely overlook the threat of their German neighbor as well before the German invasion, Marshal Semyon Timoshenko referred to the Germans as the Soviet Union's "most important and strongest enemy" and as early as July 1940, Red Army Army Chief of Staff, Boris Shaposhnikov, produced a preliminary three-pronged plan of attack for what German invasion might look like, remarkably similar to the actual attack. Since April 1941, the Germans had begun setting up Operation Haifisch and Operation Harpune to substantiate their claims that Britain was the real target. The Germans deployed one independent regiment, one separate motorized training brigade and 153 divisions for Barbarossa, which included 104 infantry, 19 panzer and 15 motorized infantry divisions in three army groups, nine security divisions to operate in conquered territories, four divisions in Finland and two divisions as reserve under the direct control of OKH. These were equipped with about 3,350 tanks, 7,200 artillery pieces, 2,770 aircraft (that amounted to 65 percent of the Luftwaffe), about 600,000 motor vehicles and 625,000–700,000 horses. Finland slated 14 divisions for the invasion, and Romania offered 13 divisions and eight brigades over the course of Barbarossa. The entire Axis forces, 3.8 million personnel, deployed across a front extending from the Arctic Ocean southward to the Black Sea. The picture was taken by Kriegsberichter Horst Grund
