Japanese Intelligence in World War II by Ken Kotani Pdf

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.

Pearl Harbor: Final Judgement by Henry C. Clausen,Bruce Lee Pdf

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.

Secret Missions by Rear-Adm. Ellis M. Zacharias Pdf

“SECRET MISSIONS” IS AN EXTRAORDINARY RECORD OF THE TWENTY-FIVE YEAR WAR OF WITS AGAINST THE JAPANESE SECRET SERVICE. This fantastic—and true—story was written by Rear Admiral Ellis M. Zacharias, the man who with one master stroke of psychological warfare broke the Japanese will to resist—before the atom bombing of Hiroshima. Long before World War II, Admiral Zacharias was sent to Japan to study the language and the country. Thrust into the world of SECRET MISSIONS, he gained an intimate knowledge of Japanese Intelligence operations and of the military’s plans to steer Japan on a course for war. Admiral Zacharias predicted Pearl Harbor, but inadequate U.S. Intelligence and the blind outlook of some of his superiors allowed the tragedy of December 7, 1941 to occur. SECRET MISSIONS takes you behind the scenes and tells you how vast Japanese spy rings sprung up on our own soil and were smashed; how Japanese codes were broken; and finally, how Admiral Zacharias broke the Japanese will to resist just before the A-bombing of Hiroshima. “An interesting and lively book”—The New Yorker “...a little frightening”—New York Times ...READS LIKE AN ADVENTURE STORY”—Booklist Index

The Elusive Enemy by Douglas Ford Pdf

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.

Double-Edged Secrets by W.J. Holmes Pdf

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.

U.S. Navy Codebreakers, Linguists, and Intelligence Officers against Japan, 1910-1941 by Steven E. Maffeo Pdf

This unique reference presents 59 biographies of people who were key to the sea services being reasonably prepared to fight the Japanese Empire when the Second World War broke out, and whose advanced work proved crucial. These intelligence pioneers invented techniques, procedures, and equipment from scratch, not only allowing the United States to hold its own in the Pacific despite the loss of most of its Fleet at Pearl Harbor, but also laying the foundation of today’s intelligence methods and agencies. One-hundred years ago, in what was clearly an unsophisticated pre-information era, naval intelligence (and foreign intelligence in general) existed in rudimentary forms almost incomprehensible to us today. Founded in 1882, the U.S. Office of Naval Intelligence (ONI)—the modern world’s “oldest continuously operating intelligence agency”—functioned for at least its first forty years with low manning, small budgets, low priority, and no prestige. The navy’s early steps into communications intelligence (COMINT), which included activities such as radio interception, radio traffic analysis, and cryptology, came with the 1916 establishment of the Code and Signals Section within the navy’s Division of Communications and with the 1924 creation of the “Research Desk” as part of the Section. Like ONI, this COMINT organization suffered from low budgets, manning, priority, and prestige. The dictionary focuses on these pioneers, many of whom went on, even after World War II, to important positions in the Navy, the State Department, the Armed Forces Security Agency, the National Security Agency, and the Central Intelligence Agency. It reveals the work and innovations of well and lesser-known individuals who created the foundations of today’s intelligence apparatus and analysis.
