Download or read book SIGINT written by Peter Matthews and published by The History Press. This book was released on 2013-09-02 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: SIGNALS INTELLIGENCE, or SIGINT, is the interception and evaluation of coded enemy messages. From Enigma to Ultra, Purple to Lorenz, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during the First and Second World War.In the First World War, a vast network of signals rapidly expanded across the globe, spawning a new breed of spies and intelligence operatives to code, de-code and analyse thousands of messages. As a result, signallers and cryptographers in the Admiralty’s famous Room 40 paved the way for the code breakers of Bletchley Park in the Second World War. In the ensuing war years the world battled against a web of signals intelligence that gave birth to Enigma and Ultra, and saw agents from Britain, France, Germany, Russia, America and Japan race to outwit each other through infinitely complex codes. For the first time, Peter Matthews reveals the secret history of global signals intelligence during the world wars through original interviews with German interceptors, British code breakers, and US and Russian cryptographers."SIGINT is a fascinating account of what Allied investigators learned postwar about the Nazi equivalent of Bletchley Park. Turns out, 60,000 crptographers, analysts and linguists achieved considerable success in solving intercepted traffic, and even broke the Swiss Enigma! Based on recently declassifed NSA document, this is a great contribution to the literature." THE ST ERMIN'S HOTEL INTELLIGENCE BOOK OF THE YEAR AWARD 2014.
Book Synopsis The British Army and Signals Intelligence During the First World War by : John Ferris
Download or read book The British Army and Signals Intelligence During the First World War written by John Ferris and published by Alan Sutton Publishing. This book was released on 1992 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Historians have paid little attention to the British Army's experience with signals intelligence during the First World War. However, this was one of the Army's most important sources of information about crucial matters such as the order of battle and intentions of the German and Turkish Armies. Britain's successes and failures in signals intelligence profoundly affected battles ranging from the race for the Channel Ports, first Somme, third Gaza and Amiens, among many others." "While efforts to weed the records on these topics have created major gaps in the sources, surviving evidence throws an entirely new light on the British Army in the Great War. It allows one to trace the evolution of the Army's signals intelligence organisations, to determine many of their successes and failures, to show how this intelligence affected various operations and, indeed, to demonstrate that signals intelligence influenced the operations of the British Army as much as those of the Royal Navy." "The material reproduced in this volume includes excerpts from reports by Army Headquarters in France, Italy and Mesopotamia and the Military Intelligence Directorate. It includes the memorandum "Enemy Codes and their Solution" by the G.H.Q. codebreaking section in January 1918, which is one of the two best sources known to exist about the techniques of "codebreaking"; surviving reports on the enemy radio networks in the Balkans and Anatolian Turkey, which are the most illuminating evidence from any theatre on the approach toward "traffic analysis" and a report on the breaking of German and Turkish Army ciphers in Mesopotamia during 1917, which is the best source known about the techniques of "cryptanalysis" used by an Army in the Great War."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Piercing the Fog written by John F. Kreis and published by Military Bookshop. This book was released on 2013-05 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the foreword: WHEN JAPAN ATTACKED PEARL HARBOR on December 7, 1941, and Germany and Italy joined Japan four days later in declaring war against the United States, intelligence essential for the Army Air Forces to conduct effective warfare in the European and Pacific theaters did not exist. Piercing the Fog tells the intriguing story of how airmen built intelligence organizations to collect and process information about the enemy and to produce and disseminate intelligence to decisionmakers and warfighters in the bloody, horrific crucible of war. Because the problems confronting and confounding air intelligence officers, planners, and operators fifty years ago still resonate, Piercing the Fog is particularly valuable for intelligence officers, planners, and operators today and for anyone concerned with acquiring and exploiting intelligence for successful air warfare. More than organizational history, this book reveals the indispensable and necessarily secret role intelligence plays in effectively waging war. It examines how World War II was a watershed period for Air Force Intelligence and for the acquisition and use of signals intelligence, photo reconnaissance intelligence, human resources intelligence, and scientific and technical intelligence. Piercing the Fog discusses the development of new sources and methods of intelligence collection; requirements for intelligence at the strategic, operational, and tactical levels of warfare; intelligence to support missions for air superiority, interdiction, strategic bombardment, and air defense; the sharing of intelligence in a coalition and joint service environment; the acquisition of intelligence to assess bomb damage on a target-by-target basis and to measure progress in achieving campaign and war objecti ves; and the ability of military leaders to understand the intentions and capabilities of the enemy and to appreciate the pressures on intelligence officers to sometimes tell commanders what they think the commanders want to hear instead of what the intelligence discloses. The complex problems associated with intelligence to support strategic bombardment in the 1940s will strike some readers as uncannily prescient to global Air Force operations in the 1990s.," Illustrated.
Book Synopsis American Signal Intelligence in Northwest Africa and Western Europe by : George Howe
Download or read book American Signal Intelligence in Northwest Africa and Western Europe written by George Howe and published by CreateSpace. This book was released on 2012-08-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume at hand, Dr. George F. Howe's American Signals Intelligence in Northwest Africa and Western Europe is important professional reading for those interested in cryptologic history or in World War II. Dr. Howe's book deals primarily with organizational matters for providing SIGINT support in combat. Thus, the reader will not find stories of high-level cryptanalysis underlying big decisions by famous leaders. In my estimation, by concentrating on the less flashy aspects of wartime support in favor of the background work, Dr. Howe has again added a dimension of great worth to our knowledge of SIGINT and of the war. The study of World War II SIGINT has concentrated, by and large, on ULTRA, the exploitation of high-grade cryptographic systems used by Germany and Japan, and the use of ULTRA material by senior wartime decision makers. This effort unquestionably is important for understanding the decisions and events of that terrible era, but the overwhelming focus on this aspect has resulted in a slightly skewed understanding. The production of ULTRA and its effective use depended on a strong and well-organized structure working in conjunction with now-legendary cryptanalysts. Since the distribution of ULTRA was limited to a small number of officers and civilian leaders, the bulk of SIGINT support to the warfighter cam from tactical SIGINT units working at or near the front lines. This is an important subject for understanding what happened in World War II and for studying the principles of SIGINT organization today.

Book Synopsis Japanese Intelligence in World War II by : Ken Kotani
Download or read book Japanese Intelligence in World War II written by Ken Kotani and published by Osprey Publishing. This book was released on 2009-09-22 with total page 0 pages. 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.
Book Synopsis Bletchley Park and D-Day by : David Kenyon
Download or read book Bletchley Park and D-Day written by David Kenyon and published by Yale University Press. This book was released on 2019-07-16 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The untold story of Bletchley Park's key role in the success of the Normandy campaign Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis' codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it. Using previously classified documents, David Kenyon casts the work of Bletchley Park in a new light, as not just a codebreaking establishment, but as a fully developed intelligence agency. He shows how preparations for the war's turning point--the Normandy Landings in 1944--had started at Bletchley years earlier, in 1942, with the careful collation of information extracted from enemy signals traffic. This account reveals the true character of Bletchley's vital contribution to success in Normandy, and ultimately, Allied victory.
Book Synopsis Secret Messages by : David J. Alvarez
Download or read book Secret Messages written by David J. Alvarez and published by . This book was released on 2000 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: To defeat your enemies you must know them well. In wartime, however, enemy codemakers make that task much more difficult. If you cannot break their codes and read their messages, you may discover too late the enemy's intentions. That's why codebreakers were considered such a crucial weapon during World War II. In Secret Messages, David Alvarez provides the first comprehensive analysis of the impact of decoded radio messages (signals intelligence) upon American foreign policy and strategy from 1930 to 1945. He presents the most complete account to date of the U.S. Army's top-secret Signal Intelligence Service (SIS): its creation, its struggles, its rapid wartime growth, and its contributions to the war effort. Alvarez reveals the inner workings of the SIS (precursor of today's NSA) and the codebreaking process and explains how SIS intercepted, deciphered, and analyzed encoded messages. From its headquarters at Arlington Hall outside Washington, D.C., SIS grew from a staff of four novice codebreakers to more than 10,000 people stationed around the globe, secretly monitoring the communications of not only the Axis powers but dozens of other governments as well and producing a flood of intelligence. Some of the SIS programs were so clandestine that even the White House—unaware of the agency's existence until 1937—was kept uninformed of them, such as the 1943 creation of a super-secret program to break Soviet codes and ciphers. In addition, Alvarez brings to light such previously classified operations as the interception of Vatican communications and a comprehensive program to decrypt the communications of our wartime allies. He also dispels many of the myths about the SIS's influence on American foreign policy, showing that the impact of special intelligence in the diplomatic sphere was limited by the indifference of the White House, constraints within the program itself, and rivalries with other agencies (like the FBI). Drawing upon military and intelligence archives, interviews with retired and active cryptanalysts, and over a million pages of cryptologic documents declassified in 1996, Alvarez illuminates this dark corner of intelligence history and expands our understanding of its role in and contributions to the American effort in World War II.
Book Synopsis Code Warriors by : Stephen Budiansky
Download or read book Code Warriors written by Stephen Budiansky and published by Knopf. This book was released on 2016 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.
