The Prague offensive was the last major military operation of World War II in Europe. The offensive was fought on the Eastern Front from 6 May to 11 May 1945. Fought concurrently with the Prague uprising, the offensive significantly helped the liberation of Czechoslovakia in 1945. The offensive was one of the last engagements of World War II in Europe and continued after Nazi Germany's unconditional capitulation on 8 May.
The city of Prague was ultimately liberated by the USSR during the Prague offensive. All of the German troops of Army Group Centre and many of Army Group Ostmark were killed or captured, or fell into the hands of the Allies after the capitulation.
