The failure of the blitzkrig

After the fierce border battles of the Red Army, the troops of the Red Army suffered such heavy losses that this gave rise to Colonel General F. Galder on July 3, 1941 to declare: "... the campaign against Russia was won within 14 days. Of course, it is not finished yet. The huge length of the territory and the stubborn resistance of the enemy using all funds will be constrained by our forces for many weeks. "
Halder was mistaken: the Red Army not only fettered significant Wehrmacht forces, but also in defensive battles in July - November inflicted sensitive losses to him. This forced Hitler in early September to admit that the defeat of Russia, which was the closest and decisive goal of the war, would not be fully achieved during 1941, and therefore the eastern campaign would have to be continued next year
