The Battle of Stalingrad 1942-43
The German defeat at Stalingrad was the culmination of Hitler's great summer offensive of 1942. The Wehrmacht's goal was to conquer the Caucasus and quench Germany's thirst for oil but the battle of the city bearing Stalin's name ultimately became Hitler's obsession. An entire army (6. Armee) and parts of a second (4. Panzerarmee) were absorbed into an urban slugfest. In November 1942, the Red Army encircled the Germans in the city and its surroundings and ultimately squeezed them to death. Roughly 91,000 soldiers surrendered by February 2, 1943. The Wehrmacht would never be the same again.
