The Russian victory in Stalingrad from 1941-1943  crushed the Germans as their first major defeat. So as you can imagine Russia went on the offensive for the one and only time. They retook everything they lost, and advanced into Germany. The battle of Berlin had begun. It would continue with the slautering, except instead of German troops slautering Russian citizens, the Russians were slautering German citizens. It didn't take long to turn Germanyb into a pile of rubble from artillery, bombs, grenades and machine guns. This battle alone would see 1,000,000 soldiers killed on both sides, but also the fall of the third Reich along with Nazi Germany.
