Under Stalin, the city became heavily industrialized as a centre of heavy industry and trans-shipment by rail and river. During World War II, Stalingrad became the center of the Battle of Stalingrad as well as a turning point in the war against Germany. Essentially, the German offensive was checked at Stalingrad. The Battle of Stalingrad lasted from August 21, 1942 to February 2, 1943, where 1.7 million to 2 million Axis and Soviet soldiers were killed, wounded or captured, in addition to over 40,000 civilians killed. The city was reduced to rubble during the fierce fighting, but reconstruction began soon after the Germans were expelled from the city.
