Available in PDF, EPUB and Kindle. Book excerpt: In the eyes of history, Japanese intelligence in World War II has fared very poorly. However, these historians have most often concentrated on the later years of the war, when Japan was fighting a multi-front war against numerous opponents. In this groundbreaking new study, Japanese scholar Ken Kotani re-examines the Japanese Intelligence department, beginning with the early phase of the war. He points out that without the intelligence gathered by the Japanese Army and Navy they would have been unable to achieve their long string of victories against the forces of Russia, China, and Great Britain. Notable in these early campaigns were the successful strikes against both Singapore and Pearl Harbor. Yet as these victories expanded the sphere of Japanese control, they also made it harder for the intelligence services to gather accurate information about their growing list of adversaries. At the battle of Midway in 1942, Japanese intelligence suffered its worst mishap when the Americans broke their code and tricked the Japanese into revealing the target of their attack. It was a mistake from which they would never recover. As the military might of Japan was forced to retreat and her forces deteriorated, so too did her intelligence services.

Available in PDF, EPUB and Kindle. Book excerpt: At the start of World War, II the U.S. Army turned to Americans of Japanese ancestry to provide vital intelligence against Japanese forces in the Pacific. Nisei Linguists: Japanese Americans in the Military Intelligence Service during World War II tells the story of these soldiers, how the Military Intelligence Service (MIS) recruited and trained them, and how they served in every battle and campaign in the war against Japan. Months before Pearl Harbor, the Western Defense Command (WDC) selected sixty Nisei soldiers for Japanese-language training. When the WDC forcibly removed more than 100,000 persons of Japanese ancestry from the West Coast, MIS continued to recruit Nisei from the relocation camps and later from Hawaii. Over the next four years, the school graduated nearly 6,000 military linguists, including dozens of Nisei women and hundreds of Caucasians. Nisei Linguists tells the remarkable story of those who served with Army and Marine units from Guadalcanal to the Philippines, Iwo Jima, and Okinawa. Their duties included translation, interrogation, radio monitoring, and psychological warfare. They staffed theater-level intelligence centers such as the Allied Translator and Interpreter Section in the Southwest Pacific Area. In China, Burma, and India they served with the Office of Strategic Services, Merrill’s Marauders, and Commonwealth forces. Others served with the Army Air Forces or within the continental United States. At war’s end, the Nisei facilitated local surrenders of Japanese forces as well as the occupation. Working in military government, war crimes trials, censorship, and counterintelligence, the MIS Nisei contributed to the occupation’s ultimate success.

Available in PDF, EPUB and Kindle. Book excerpt: This account of the top secret investigation is “essential history . . . the authoritative appraisal of why American armed forces met the Japanese attack asleep” (The Christian Science Monitor). On December 6, 1941, Admiral Husband E. Kimmel, commander in chief of the United States Pacific Fleet, assured his staff that the Japanese would not attack Pearl Harbor. The next morning, Japanese carriers steamed toward Hawaii to launch one of the most devastating surprise attacks in the history of war, proving the admiral disastrously wrong. Immediately, an investigation began into how the American military could have been caught so unaware. The results of the initial investigation failed to implicate who was responsible for this intelligence debacle. Secretary of War Henry L. Stimson, realizing that high-ranking members of the military had provided false testimony, decided to reopen the investigation by bringing in an unknown major by the name of Henry C. Clausen. Over the course of ten months, from November 1944 to September 1945, Clausen led an exhaustive investigation. He logged more than fifty-five thousand miles and interviewed over one hundred military and civilian personnel, ultimately producing an eight-hundred-page report that brought new evidence to light. Clausen left no stone unturned in his dogged effort to determine who was truly responsible for the disaster at Pearl Harbor. Pearl Harbor: Final Judgement reveals all of the eye-opening details of Clausen’s investigation and is a damning account of massive intelligence failure. To this day, the story surrounding the Japanese attack on Pearl Harbor stokes controversy and conspiracy theories. This book provides conclusive evidence that shows how the US military missed so many signals and how it could have avoided the events of that fateful day.

Download or read book Double Edged Secrets written by W.J. Holmes and published by Naval Institute Press. This book was released on 2013-01-15 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the foreword to this book, first published in 1978, Sen. Daniel Inouye describes the story as ""the raw material of adventure fiction--but this is all true and told in a manner that is at the same time fascinating and professional."" Despite the passage of twenty years and the appearance of several studies of code breaking, this inside look at naval intelligence in the Pacific is as powerful as ever. This book provides a compassionate and unique understanding of the war and the business of intelligence gathering. Assigned to the combat intelligence unit in Honolulu from June 1941 to the end of the war, W. J. Holmes shares his history-making experiences as part of an organization that collected, analyzed, and disseminated naval intelligence throughout World War II. His book not only captures the mood of the period but gives rare insight into the problems and personalities involved, allowing the reader to fully appreciate the painful moral dilemma faced daily by commanders in the Pacific once the Japanese naval codes were broken. Every time the Americans made use of the enemy messages they had decoded, they increased the probability of the Japanese realizing what had happened and changing their codes. And such a change would cause the U.S. Pacific Fleet to lose a vital edge. On the other hand, withholding the information could--and sometimes did--result in the loss of U.S. lives and ships. This revealing study illuminates the difficulties in both collecting intelligence and deciding when to use it.

Download or read book Secret Missions written by Ellis M. Zacharias and published by Naval Institute Press. This book was released on 2014-03-15 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Elusive Enemy written by Douglas Ford and published by Naval Institute Press. This book was released on 2011-10-15 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Elusive Enemy explores the evolution of U.S. intelligence concerning the combat capabilities of the Imperial Japanese Navy and its air arm during the interwar period and the Pacific War. Ford contends that the US Navy could not accurately determine the fighting efficiency of Japan’s forces until it engaged them in actual battle conditions over an extended period. As the conflict progressed, the Americans were able to rely on a growing array of intelligence material, including POWs, captured documents, and specimens of captured enemy weapons. These sources often revealed valuable information on the characteristics of Japanese equipment, as well as some of the ideas and doctrines which governed how they carried out their operations. First-hand observations of the Japanese navy’s performance in battle were the most frequently used source of intelligence which enabled the US Navy to develop a more informed assessment of its opponent. Ship crews, along with US aviators, were tasked to collect information by making a thorough observation of how the Japanese fought. Action reports described how the Imperial fleet demonstrated a number of weaknesses, the most important of which was a shortage of modern equipment and, after 1942, diminished air power. Yet, he demonstrates how the Japanese remained a resilient enemy who could be defeated only when the Americans deployed sufficient equipment and used it in an appropriate manner. The Office of Naval Intelligence, as well as the intelligence services operating in the Pacific theater, thus had to assess a wide array of conflicting characteristics, and provide a balanced evaluation concerning the strengths and weaknesses of the Imperial navy. At the same time, a large part of the intelligence analysis was undertaken by commanders in the Pacific Fleet. Naval personnel and aircrews assessed the information gained through encounters with the enemy so that they could develop a set of methods whereby US forces were able defeat the Japanese without incurring excessive casualties and losses. The intelligence services, in turn, played an important role in disseminating the information on the most efficient tactics and weapons that could be used to defeat the Imperial Fleet. The Elusive Enemy aims to explain how American perceptions concerning the Japanese navy evolved during the conflict, with a particular focus on the role of intelligence. It also seeks to introduce a new perspective on the question as to why the U.S. Navy carried out its campaigns during the Pacific War in the manner that it did.
Download or read book Pearl Harbor Revisited written by Frederick D. Parker and published by CreateSpace. This book was released on 2012-07-31 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of the U.S. Navy's communications intelligence (COMINT) effort between 1924 and 1941. It races the building of a program, under the Director of Naval Communications (OP-20), which extracted both radio and traffic intelligence from foreign military, commercial, and diplomatic communications. It shows the development of a small but remarkable organization (OP-20-G) which, by 1937, could clearly see the military, political, and even the international implications of effective cryptography and successful cryptanalysis at a time when radio communications were passing from infancy to childhood and Navy war planning was restricted to tactical situations. It also illustrates an organization plagues from its inception by shortages in money, manpower, and equipment, total absence of a secure, dedicated communications system, little real support or tasking from higher command authorities, and major imbalances between collection and processing capabilities. It explains how, in 1941, as a result of these problems, compounded by the stresses and exigencies of the time, the effort misplaced its focus from Japanese Navy traffic to Japanese diplomatic messages. Had Navy cryptanalysts been ordered to concentrate on the Japanese naval messages rather than Japanese diplomatic traffic, the United States would have had a much clearer picture of the Japanese military buildup and, with the warning provided by these messages, might have avoided the disaster of Pearl Harbor.
