It is 1944, the peak of World War II. The Allies are bombing Axis fuel depots in Romania to sap the Germans of precious energy resources, but the 15th Air Force is paying a heavy cost. Dozens of bombers are shot down over Yugoslavia, and many of the air crew are forced to bail out behind enemy lines. Nobody knows how many have survived, if they are in prisoners of war, or who is holding them. In Italy, a small cadre of men from the Office of Strategic Services learns that Serbian Chetnik forces, led by General Dragoljub 'Draža' Mihailovich, are sheltering dozens - perhaps hundreds - of Allied men in their homes and farms. It is up to the tiny O.S.S. team, codenamed HALYARD, to find a way get them back. 'HALYARD' is a fictionalized account of a true, but largely unknown, operation. It tells the story of how three men - 'Guv' Musulin, Mike Rajachich, and Arthur 'Jibby' Jibilian - parachuted behind enemy lines and, with the help of the Serbian Chetniks, pulled off one of the most daring military rescue operations in American history.
