Question

how did Hitler defeat Russia

Answer 1

The German Blitzkrieg technique was used and was as devastating in Russia as it was in the rest of Europe. The war of annihilation waged by the Nazis against the Soviets with no mercy . One week into the German invasion, 150,000 Soviet soldiers were dead or wounded that were more than during the five months of the Battle of the Somme.
As the German armies went further into the Russian land, one million Soviet troops were drafted to protect Kiev. Despite Stalin's cruel order forbidding any city to capitulate, Kiev fell and 600,000 Soviet soldiers were arrested. By October 1941, three million Soviet soldiers were prisoners of war.
