From: gnu@toad.com (John Gilmore) This book is part of a series from the Office of Air Force History. It is mostly an interview with Supreme Court Justice Lewis Powell, Jr. about his role in World War II. Powell worked in intelligence in the Army Air Force in North Africa and then in the US Strategic Air Forces Headquarters in Europe. He received ULTRA information and briefed the American commanders on it. ULTRA was information derived from decoding German transmissions, which were encoded in the Enigma cipher, and then merged with other information at Bletchley Park, England. Special care had to be taken to never reveal information that only Enigma decryptions could have provided, so the Germans would not suspect that it had been compromised. Instead, it was used to guide other sources of information (e.g. telling photo-reconnaisance planes what general area to look in) so that if the Germans investigated, they would always find another way for the Allies to have received the information. A very small number of people actually received ULTRA information directly; they guided others in gathering information from other sources and in downplaying information that ULTRA contradicted. In fact, the ULTRA secret was kept until 1967, and only commonly known after 1974. Its revelation caused much re-examination of WWII history as books were written and papers about it were gradually declassified (some were still classified in 1987 when the book was written -- and probably still are today). The book focuses very little on the cryptanalysis involved, though Powell describes the setup at Bletchley Park, which he visited for training; its focus is how the information was disseminated through the military, how it was used, and what effect it had on the war. The book is noteworthy for its many detailed footnotes cross-referencing to other sources of information, particularly in the National Archives "Records Group 457" NSA/CSS records, and to many histories of the war. Justice Powell also reminisces about many of the people involved in providing and using the ULTRA information, and biographies of these people have been added in footnotes. Curiously enough, most of the intelligence corps was recruited from civilian lawyers; it was said that "Special Branch was the best law firm in Washington". I cynically wonder if today's intelligence corps disregard for the law comes from being originally staffed with lawyers. ULTRA and the Army Air Forces in World War II, Lewis F. Powell Jr, Diane T.
