Since the revelation of the so-called Ultra Secret, the importance of codebreaking and signals intelligence in the diplomacy and military operations of World War II has become increasingly evident. No history of the war is complete without a careful consideration of the role of cryptanalysis. Studies of wartime signals intelligence, however, have largely focused on Great Britain and the United States and their successes against, respectively, the German Enigma and Japanese Purple cipher machines. Drawing upon newly available sources in Australia, Britain, China, France, and the United States, the ten studies in this volume demonstrate that the codebreaking war was a truly global conflict in which many countries were active and successful.
