Operation Halyard

Home > SOF History > Operation Halyard

In the summer of 1944, during World War II, hundreds of Allied airmen were stranded behind enemy lines in German-occupied Yugoslavia. The Office of Strategic Services (OSS) and Yugoslavian resistance forces conducted Operation Halyard to evacuate the downed airmen to safety.

Operation Halyard

Operation Halyard became one of the largest rescue operations of Allied airmen behind enemy lines during World War II. OSS operatives parachuted into German-held Serbia to help organize the evacuation of downed American and Allied airmen. A three-man OSS team linked up with Serbian Chetniks led by General Draza Mihailovic in August 1944. The team was assigned to the United States Fifteenth Air Force and designated as the 1st Air Crew Rescue Unit. [1]

Local communities sheltered the airmen and resistance fighters provided protection and constructed an improvised airstrip near the village of Pranjani, Serbia. Allied aircraft were able to fly into enemy-held territory to evacuate the airmen. Serbia had formed part of the prewar Kingdom of Yugoslavia but was under German military occupation when the operation occurred.

The operation, using C-47 transport planes, took place from August to December 1944. Operation Halyard would ultimately rescue more than 500 Allied airmen. Among those rescued were 432 American airmen and 80 other Allied personnel.
