"The Ultra Americans has some secrets of its own to spill : the never-before-told episode of the American general who knew the Ultra secret and was captured by the Nazis ; why the hero who led the first raid over Tokyo, General Jimmy Doolittle, thought he could defy the Ultra regulations ; how one American in the Ultra team forecast the Battle of the Bulge, and what was done about his advance information ; the truth about the bombing of Dresden ; how General Patton used Ultra intelligence to score on the battlefield ; and the TICOM mission that took Americans and Britons from the Ultra operation into newly defeated Germany for what was to become the beginning of the Cold War. The book also gives a full account of how the Japanese ambassador in Berlin gave away hundreds of Nazi secrets by transmitting them to Tokyo in Japanese codes that had been broken by the Americans. Above all, this is the true story of Americans fighting a brutal enemy with their brains - and winning." --from inside jacket.
