In the Battle of Stalingrad, Germany and its allies fought the Soviet Union for control of the city of Stalingrad in Southern Russia. Marked by fierce close-quarters combat and direct assaults on civilians in air raids, it is one of the bloodiest battles in the history of warfare, with an estimated 2 million total casualties. After their defeat at Stalingrad, the German High Command had to withdraw considerable military forces from other theaters of war to replace their losses.
