In the summer of 1944, the skies over Nazi-occupied Yugoslavia became a graveyard for Allied aircraft. Hundreds of American and Allied airmen, shot down during bombing raids on Romanian oil fields and Axis supply lines, found themselves stranded deep in enemy territory — hunted, wounded, and waiting. What followed was one of the most audacious rescue operations of the entire war. Operation Halyard was born in secrecy. A three-man OSS team — Lieutenant George Musulin, Master Sergeant Michael Rajacich, and radio specialist Arthur Jibilian — parachuted behind German lines and made contact with Serbian Chetnik forces under General Draža Mihailovic. Together, they constructed makeshift airstrips in the Serbian hills and coordinated a fleet of C-47 cargo aircraft flying out of Italy, daring to land in broad daylight beneath the watch of German patrols. Between August and December 1944, over 500 Allied airmen — among them 432 Americans — were lifted from the valleys and forests of occupied Serbia and returned to Allied bases. The Serbian villagers who sheltered these men risked everything: their homes, their families, their lives. Yet for decades, the story was deliberately buried by American, British, and Yugoslav governments, its heroes denied recognition, its architect executed by a postwar communist tribunal.
