German Pioneers Cutting Barbed Wire

Operation Barbarossa - German pioneers cutting through barbed wire on the German-Soviet demarcation line behind the Granitza River at the beginning of the Russian campaign. On June 22, 1941, more than 3 million German and Axis troops invaded the Soviet Union along an 1,800-mile-long front, launching Operation Barbarossa. It was Germany’s largest invasion force of the war, representing some 80 percent of the Wehrmacht, the German armed forces, and one of the most powerful invasion forces in history.
