Combined Fleet Decoded offers a profoundly new perspective on the naval war in the Pacific during World War II, examining every aspect of the secret war of intelligence - from radio dispatches and espionage to vital information obtained from prisoners, document translation, and even deepsea divers' recoveries of critical material from wrecks at the bottom of the sea. John Prados's text covers both the Allies and the Japanese and relates the growing intelligence knowledge to the progress and outcome of Pacific naval actions. Combined Fleet Decoded also tells the stories of many of the key individuals whose personalities and conflicts shaped the secret intelligence war - including intelligence officers in the Imperial Japanese Navy.
