Focusing on the wartime activities of the U.S. Office of Strategic Services (OSS) in Axis-controlled Yugoslavia during World War II, this book chronicles American policy, plans for sending aid and agents, and the establishment of the first training bases in North Africa and the Mediterranean. OSS missions and field operation with the Chetniks and partisans are cataloged and analyzed for the first time, along with OSS views on Yugoslav border claims against Italy and Austria, the OSS position on Slovenia in postwar Yugoslavia, and the role of Yugoslavs cooperating within the OSS.
