The Axis conquers huge areas of the Soviet Union and causes heavy losses on the Red Army but fails in its overall strategic goal of defeating the Soviets in a Blitzkrieg campaign.
Operation Barbarossa (German: Unternehmen Barbarossa, named after Frederick I) was the code name for the European Axis invasion of the Soviet Union during World War II. It began on 22 June 1941. More than 3 million men attacked along the 2,900 km front, which made it the largest military invasion in human history. It also involved 600,000 motor vehicles and 750,000 horses.
