The Battle of Stalingrad was a major battle on the Eastern Front of World War II in which Nazi Germany and its Axis allies fought the Soviet Union for control of the city of Stalingrad in southern Russia. Marked by intense close-quarters combat and heavy civilian losses during aerial bombardment, the battle is considered the largest and deadliest urban battle in military history and the largest battle in World War II. By the end of the fighting, the German 6th Army had been destroyed, the 4th Panzer Army had suffered severe losses, and Army Group B was routed. The defeat reversed the momentum of Hitler's invasion of the Soviet Union and shifted the balance on the Eastern Front in the Soviet Union's favour.
