The Stalingrad campaign was a major turning point of World War II. The German Sixth Army's 22 divisions and 250,000 troops were encircled and destroyed, while the Soviet 62nd Army's desperate defense of the city and the suffering of the starving German troops receives much justifiable attention. Here, Soviet armor expert William E. Hiestand draws attention to the less-covered element of the battle: the reborn Soviet tank and mechanized corps that delivered the death blow to Hitler's hopes. He explains how in summer 1942, the Soviet tank forces were failing to reach their potential; despite being equipped with superb T-34 and heavily armored KV-1 tanks, the Red Army's newly formed tank corps were unable to integrate their armored thrusts with supporting infantry and artillery, and their disjoined attacks were repeatedly shattered. By November 19, however, Soviet organization, command and control, training, and tactics had matured, allowing the Fifth Tank Army to launch the decisive penetration through the Romanian Third Army.
