US NAVYS ON-THE-ROOF GANG 2/E
內容簡介
THE US NAVY'S ON-THE-ROOF GANG: VOLUME I - PRELUDE TO WAR is a narrative nonfiction account of the unknown true-life story of the "On-The-Roof Gang," the U.S. Navy's fledgling radio intelligence organization in the years leading up to World War II. It is based on the real life of Harry Kidder, a U.S. Navy radioman who first discovered and deciphered Japanese katakana telegraphic code while stationed in the Philippines in the 1920s, discovering the he was listening to Imperial Japanese Navy (IJN) radio communications. Kidder strongly believed in the future of radio intelligence and a chance meeting with Lieutenant Laurance Safford led to the birth of the Navy's Radio Intelligence community. Kidder taught others the nascent art of intercepting IJN communications on the roof of the Main Navy Building in Washington, DC. From 1928 to 1941, 176 Sailors and Marines attended this training and were then stationed as radio intercept operators around the Pacific. These men would become known as the On-The-Roof Gang and were charged with keeping track of the IJN as they prepared for war with the United States. The circumstances of America's entry into World War II hinged on success or failure of the On-The-Roof Gang, and Harry Kidder knew this. On-the-Roof Gang: Prelude to War concludes with the "date which will live in infamy," December 7, 1941.
The dit-dah combinations of telegraphic code boomed through Harry Kidder's headset, and he should have been able to copy it with his eyes closed. This transmission, however, baffled him, with characters he had never heard before. He was an expert U.S. Navy radioman-one of the best in the Asiatic Fleet-and eventually his curiosity led him to discover he was listening to Imperial Japanese Navy (IJN) radio communications. He didn't know it at the time, but this discovery would set in motion events that would lead to the birth of the U.S. Navy's communications intelligence community.
Kidder taught others the nascent art of intercepting IJN communications on the roof of the Main Navy Building in Washington, DC, and they became known as the On-The-Roof Gang. He recognized that the circumstances of America's entry into World War II hinged on success or failure of the On-The-Roof Gang.
Follow the professional and personal life of Harry Kidder-full of intrigue, war, love, and loss-as he prepared the Gang for the U.S. Navy's confrontation with the IJN. On-the-Roof Gang: Prelude to War follows Kidder and the Gang along the inexorable path toward war, concluding with the "date which will live in infamy," December 7, 1941.
