Western Allied invasion of Germany The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II.

This is known as the "Central Europe Campaign" in United States military histories.
Operation Weserübung Operation "Weserübung" (] ) was the code name for Germany's assault on Denmark and Norway during the Second World War and the opening operation of the Norwegian Campaign. The name comes from the German for Operation Weser-Exercise ("Unternehmen Weserübung"), the Weser being a German river.
