S1, E5: In 1942 some of the fiercest combat that ever took place was in the monumental battle between the German and Russian armies. The ground was covered with bombs and artillery shells; almost all of Stalingrad was reduced to rubble. Of some 46,000 affected homes and villages, 41,000 were totally destroyed. In Stalingrad two million soldiers fought for 200 days and nights. Many people in the West doubted that the Soviets could win against the mighty Wehrmacht, but the Red Army fought the Nazis to a standstill. From street to street, house to house, room to room, the Russians repelled attack after attack, causing Hitler's army to suffer its greatest losses to date. So much was at stake that the victory or defeat of either side might well determine the outcome of World War II.
