This book was released on 2015-12-10 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to provide an authentic and reliable guide to U.S. communications intelligence (COMINT) during World War II. A complete history of this subject would be an overwhelming task; therefore, I have limited this effort to matters of high-level policy, administration, and organization, I have tried to show how communications intelligence was controlled and directed by each service and how these services related to each other and to their British counterparts. This is not a history of cryptanalysis or COMINT operations, nor is there much here about the specific uses made of COMINT. Nevertheless, within these limits, l have tried to be complete. That is, I have made an effort to show not only how Army and Navy COMINT activities were run but also how COMINT was structured in the Coast Guard, FBI, and Federal Communications Commission {FCC). There is also a great deal here on the non-COMINT producing agencies - the Military Intelligence Service (MIS) and the Office of Naval Intelligence QONI). In fact, my account as it relates to the Army has more to do with the MIS than with Arlington Hall, I hope the reasons for this will be made clear in the text, Much of this study seems to be concerned with service politics and interservice disagreements. I can only say that I recognize that COMINT was often produced in spite of certain high-level maneuverings. On that same theme, I also recognize that the people who produced the real COMINT product are, in this study, quite secondary figures, There is little here about Frank Rowlett, Solomon Kullback, or Frank Raven. A word about the British. This study could almost be subtitled "The Development of a COMlNT Alliance." The emphasis on British intelligence is an absolute must for a policy and administrative history, because there is no understanding of the development of U.S. COMINT without continually reporting and examining the role of the British. The sources used in this book are adequately identified in the footnotes and the sources section. I have used the footnotes to report a great deal of supplementary information, and I hope that the reader will turn to them.
Book Synopsis A History of US Communications Intelligence During WWII by : Robert Louis Benson
Download or read book A History of US Communications Intelligence During WWII written by Robert Louis Benson and published by www.Militarybookshop.CompanyUK. This book was released on 2011-01-01 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the onset of World War II, the American organizations responsible for the vital wartime function of communications intelligence (COMINT) were forced to change drastically. In addition to the daunting challenges of rapid operational expansion, the peacetime processes of U.S. Army and Navy COMINT proved inadequate to support active military operations on a worldwide scale. With national survival and individual lives at stake, more information, and its timely dissemination to both U.S. forces and those of its close ally, the United Kingdom, quickly became a top priority. "A History of U.S. Communications Intelligence during World War II: Policy and Administration" tells the story of the profound organizational changes wrought on U.S. COMINT by rapid expansion, urgent requirements for information, and international agreements. While the services never completely solved the problems posed by these challenges, by war's end they had created structures and implemented policies which, however cumbersome, achieved high levels of combat support. After covering the initial year of expansion, this study examines such issues as: The Army-British COMINT agreement of 1943 and the ENIGMA crisis; British-U.S. Navy COMINT agreements in 1943 and 1944; Jurisdictional problems regarding clandestine communications; Army and Navy movement to full cooperation, 1944-1945; Internal organizational developments in the Army and Navy. In addition to this comprehensive cover of organizational issues, "A History of U.S. Communications Intelligence during World War II" also sheds new light on the U.S.-UK controversy over U.S. denial of Alan Turing's access to scrambler technology developed at Bell Labs, conflicts between the Director of Naval Intelligence and J. Edgar Hoover's FBI over sharing intelligence information, and the tension between Army and Navy COMINT and the OSS, which had its own methods of obtaining data from British intelligence sources. Scholars and intelligence professionals alike will find much of value in this detailed and copiously documented study.

Book Synopsis Pearl Harbor Revisited by : Frederick D. Parker
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.

Book Synopsis Double-Edged Secrets by : W.J. Holmes
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.
Book Synopsis Pearl Harbor Revisited by : Frederick D. Parker
Download or read book Pearl Harbor Revisited written by Frederick D. Parker and published by Createspace Independent Publishing Platform. This book was released on 2017-03-08 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series as a whole and this volume in particular are unique in many ways but primarily because they represent a closely analyzed, comprehensive examination of the COMINT record juxtaposed with extensive research into the written history of events. Mr. Parker's work also includes research into the Japanese Navy messages which remained untranslated until 1945 and undiscovered until now. These messages revealed the Japanese Navy plans for war with the United States, Great Britain, and the Netherlands and the preliminary exercises that occurred in the months prior to Pearl Harbor. This activity clearly signaled the creation of a massive carrier strike force with the major naval objective somewhere in the Pacific Ocean far distant from either Indochina or the Philippines. This comparison of the COMINT record with the published material covering the same period will benefit not only NSA but also the academic community, which continues to pursue the history of the Second World War. Thus whether or not the results agree with the literature, particularly if they do not, the effort to create an "official" COMINT history is more than justified. Mr. Parker's perseverance, diligent research, and detailed analysis have made this a significant and unique contribution to U.S. COMINT history, U.S. military history, and U.S. history.

Book Synopsis Historical Dictionary of World War II Intelligence by : Nigel West
Download or read book Historical Dictionary of World War II Intelligence written by Nigel West and published by Scarecrow Press. This book was released on 2007-11-12 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years immediately following World War II, information was disclosed about what has been termed the shadow war of the existence of hitherto secret agencies. In Germany it was the Abwehr and the Sicherheitsdienst; in Britain it was MI5, the Secret Intelligence Service (MI6) and Special Operations Executive (SOE); in the United States it was the Office of Strategic Services (OSS) and the Special Intelligence Service (SIS) of the Federal Bureau of Investigation (FBI); in Japan it was the Kempet'ai; and in Italy the Servicio di Informazione Militare (SIM). Sixty years after World War II secrets are still being revealed about the covert activities that took place. Many countries had secret agencies maintaining covert operations, but even ostensibly neutral countries also conducted secret operations. Changes in American, British, and even Soviet official attitudes to declassification in the 1980s allowed thousands of secret documents to be made available for public examination, and the result was extensive revisionism of the conventional histories of the conflict, which previously had excluded references to secret intelligence sources. The Historical Dictionary of World War II Intelligence tells the emerging history of the intelligence world during World War II. This is done through a chronology, an introduction, a bibliography, and hundreds of cross-referenced dictionary entries on the secret agencies, operations, and events. The world of double agents, spies, and moles during WWII is explained in the most comprehensive reference currently available.

Available in PDF, EPUB and Kindle. Book excerpt: This book is part of the Army historical community's commemoration of the fiftieth anniversary of World War II. American victory in that conflict was brought about not only by the valor of our fighting men and the immensity of our productive capacity, but also by the availability of superb military intelligence. Much of this intelligence came from the ability of our armed forces to intercept and decipher the most secret communications of their adversaries. For many years security considerations prevented any public mention of these successes in the office histories. Now much of the story can be told. To preserve the memory of the Army's role in this intelligence war, a collection of documents on Army signals intelligence in World War II Signal II were published. This book is intended both for an Army audience and for the general public - including those World War II veterans who participated in the signals intelligence war and who for so many years were constrained to keep their contributions secret. The security barriers have now been lifted, and the Army is proud to acknowledge those contributions.
