The battle of Stalingrad was a warlike confrontation between the Red Army of the Soviet Union and the Wehrmacht of Nazi Germany and its Axis allies for the control of the Soviet city of Stalingrad, current Volgograd, between August 23, 1942 and the February 2, 1943. The battle took place during the German invasion of the Soviet Union, during the Second World War. With estimated casualties in more than two million people between soldiers of both sides and Soviet civilians, the Battle of Stalingrad is considered the bloodiest battle in the history of mankind. The serious defeat of Nazi Germany and its allies in this city meant a key and severe turning point in the final results of the war and represents the beginning of the end of Nazism in Europe, because the Wehrmacht would never recover its previous strength nor would it obtain more strategic victories on the Eastern Front.
