Operation Retribution (German: Unternehmen Strafgericht) or Operation Punishment was the April 1941 German bombing of Belgrade, the capital of Yugoslavia, in retaliation for the coup d'état that overthrew the government that had signed the Tripartite Pact. The bombing occurred in the first days of the German-led Axis invasion of Yugoslavia during World War II. The Royal Yugoslav Army Air Force (VVKJ) had only 77 modern fighter aircraft available to defend Belgrade against the hundreds of German fighters and bombers that struck in the first wave early on 6 April. Three days prior, VVKJ Major Vladimir Kren had defected to the Germans, disclosing the locations of multiple military assets and divulging the VVKJ's codes. Three more waves of bombers attacked Belgrade on 6 April, and more attacks followed in subsequent days. The attacks resulted in the paralysis of Yugoslav civilian and military command and control, the widespread destruction of Belgrade's infrastructure, and many civilian casualties. The ground invasion had begun a few hours earlier, and air attacks were also made on VVKJ airfields and other strategic targets across Yugoslavia.
