The war with the Soviet Union, despite the initial victories, developed for the German command in a slightly different scenario than with Poland or the Western European countries. The Blitzkrieg plan (Operation Barbarossa) involved the capture of Moscow during the first 10-12 weeks of the war. However, despite the successes of the Wehrmacht in the early days of the offensive, the increased resistance of the Red Army and a number of objective reasons prevented its implementation.
