The April War or Operation 25
The invasion of Yugoslavia, also known as the April War or Operation 25, was a German-led attack on the Kingdom of Yugoslavia by the Axis powers which began on 6 April 1941 during World War II. The order for the invasion was put forward in “Führer Directive No. 25”, which Adolf Hitler issued on 27 March 1941, following the Yugoslav coup d’état.
