When Hitler invaded the Soviet Union in June 1941, the German Army annihilated a substantial part of the Red Army. Yet the Soviets rebounded to successfully defend Moscow in late 1941, defeat the Germans at Stalingrad in 1942 and Kursk in 1943, and deliver the deathblow in Belarus in 1944. Eastern Front expert Walter Dunn examines these four pivotal battles and explains how the Red Army lost a third of its prewar strength, regrouped, and beat one of the most highly trained and experienced armies in the world.
