"Permanent friends, permanent interests": Anglo-American cooperation in naval intelligence during the Second World War
Bath, Alan Harris
Doctor of Philosophy thesis
Anglo-American cooperation in naval intelligence during the Second World War was closer and more productive than any similar relationship between other sovereign nations in recent history. Although thought of as a product of the "special relationship" between the United States and the United Kingdom, intelligence cooperation was based less on cultural affinities and more on practical considerations of individual advantage to the nations involved. Cooperation grew from British initiative, based on the need to involve the United States as deeply as possible in the battle against Germany. It was at its most productive in the successful battle against German U-boats in the Atlantic. As confidence in eventual Allied victory supplanted mutual concern for survival, cooperation gradually weakened, and post-war national interests began to overshadow wartime exigencies; and naval intelligence cooperation waned.
