Throught the entire period from 22 June 1941 through 6 June 1944, Germany devoted its greatest strategic attention and the bulk of its military resources to action on its Easter Front. During this period, Hitler maintained a force of almost 4 million German and other Axis troops in the East fighting against a Red Army force that rose in strength from under 3 million men in June 1941 to over 6 million the summer of 1944. While over 80 percent of the Wehrmacht fought in the East during 1941 and 1942, over 60 percent continued to do so in 1943 and 1944.

Page 14 breaks down the German casualties.
