The Albanian Operation, carried out by British and American secret services from 1949 to 1953, was one of the first Western attempts to subvert a country behind the Iron Curtain. The British liaison officer for the project in Washington was Kim Philby, a Soviet double agent who sabotaged the whole venture. In all, about 300 agents and civilians are thought to have been killed in the disastrous operation. The story was first pieced together by Nicholas Bethell in his 1984 book The Great Betrayal: The Untold Story of Kim Philby's Biggest Coup, based on interviews and conversations with British and American officials and Albanian fighters who infiltrated the Stalinist Albanian regime and escaped alive. The present work presents the interviews and throws new light on what actually took place.
