When Hitler invaded the Soviet Union in June 1941, the German Army quickly annihilated a major portion of the Red Army. Yet the Red Army 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. Dunn examines these 4 battles while explaining how the Soviets lost a third of their prewar army yet returned to beat one of the most highly trained and experienced armies the world has ever seen.
