History of the Navy Operation Plans and Orders

On October 28, 1944, the Japanese cruiser Nachi arrived in Manila Bay, along with several other vessels, to provide support to Japanese reinforcements landing at Leyte. Beginning the next day, Nachi came under attack by American forces from Task Group 38.2, until she was finally sunk off Corregidor on November 5 by aircraft from U.S.S. Lexington (Aircraft carrier: CV-16). After American forces recaptured Manila in March 1945, divers from U.S.S. Chanticleer (Submarine rescue ship: ASR-7) dove on the wreck and recovered classified Japanese Navy planning documents. Upon being returned to the General Headquarters of the Southwest Pacific Area, General Douglas MacArthur ordered that the documents be translated and distributed by the Allied Translator and Interpreter Section.
