This is the true story of an American nuclear submarine's desperate search for a nuclear-armed Soviet submarine lost in the depths of the north Pacific. Told by a sailor on board the U.S. spy sub, it reads like a techno-thriller, but the events recorded here actually happened. To this day - some twenty-eight years later - the U.S. Navy has never publicly admitted the operation took place. The mission remains so sensitive that it is still classified "compartmentalized top secret". With slight technical modifications and name changes, however, Roger Dunham's story was cleared for publication by the Department of Defense. It offers the first eyewitness account of what the Pentagon calls one of the most successful military operations of the Cold War. Dunham brings readers into his submarine as the crew struggles to accomplish their mission in spite of flooding, emergency shutdowns of the nuclear reactor, depletion of uranium fuel, the loss overboard of a chief petty officer, and the mental breakdown of a crewman vital to the engine room. The ultimate success of this dangerous operation earned the crew the Presidential Unit Citation, presented in a top secret ceremony.

Zimmerman reveals how the Tizard Mission established an effective system of teamwork for Allied technical and scientific co-operation, a teamwork that proved to be a crucial factor in Allied technical superiority.

An instant bestseller when it was first published in 1946, this memoir recounts the author's nearly forty years of service in naval intelligence, beginning in 1908. One of the first to venture into the realm of psychological warfare, Ellis Zacharias was awarded the Legion of Merit with two gold stars for his contributions. Among the highlights of his impressive career was the role he played in convincing the Japanese to accept surrender in 1945, a subject he deals with in fascinating detail in this book. Zacharias gives readers access to rare psychological profiles that he prepared for the Office of Naval Intelligence on leading political and military figures in Japan. His book also recounts his exploits as a young naval attaché with the U.S. Embassy in Tokyo in the early 1920s. In the early months of the war readers join him in the thick of combat in the Pacific, first aboard a cruiser under his command and later in a battleship. Of particular interest are descriptions of his one-man radio broadcasts beamed at Japan between V-E and V-J days that received kudos from Adm. Ernest J. King for helping bring about the surrender.
