Historians concerned with Yugoslavia's role in World War II will find much of interest in this massive monograph on the policies of the three major Allied powers in the early years of the war. For the most part it is a study of British policy, solidly based on the archives of the Foreign Office and other agencies, with less attention to Soviet and U.S. policy; for the former the source material is not at hand, and Washington was not in the forefront at this time, generally deferring to the British in the Balkan area. The research is most thorough. The story unfolds day by day, and no fact, opinion or decision, relevant or irrelevant, escapes the author's notice.
