Hitler's Wehrmacht invades the Soviet Union in 1941; the invasion had been planned under the name Barbarossa.
Hitler prophesies that Moscow will be destroyed; his armies do indeed reach the city limits, but supplies fail to arrive, as the Wehrmacht is unprepared for winter; the Germans also encounter problems before reaching Leningrad.
The longer the war in the Soviet Union lasted, the more important propaganda became on the home front; footage from various sections of the front helped with this; Hitler intended to deliver a decisive blow with the capture of Stalingrad.
