Nazism and the Rise of Hitler — Social Studies STD 9 — Question

Hitler invaded the USSR on June 22nd 1941. It was what lost him the war. Over 80 percent of the German’s 5 million war casualties (military) were in Russia. The ultimate result is that the Russians steamrolled the Germans back right into Berlin. The Russians suffered 26 million people lost in the war (10 million were civilians) fighting the Germans.
The Germans in 1943 had 3.5 million troops in 150 Divisions on the Eastern Front, they barely had 42 Division to fact the Western allies even after the Normandy landings. Hitler managed to divert 750,000 troops to Normandy but that wasn’t enough.
By 1945 the Russians had pushed the Germans back to the Oder River barely 60 miles from Berlin and the Germans had only 1.5 million troops left to defend Germany. The Russians had 12 million closing in from the East and the Western allies had 4 million pushing across the Rhine. Germany was doomed.
