Allied and Axis Signals Intelligence in World War II by David Alvarez Pdf
The importance of codebreaking and signals intelligence in the diplomacy and military operations of World War II is reflected in this study of the cryptanalysts, not only of the US and Britain, but all the Allies. The codebreaking war was a global conflict in which many countries were active. The contributions reveal that, for the Axis as well as the Allies, success in the signals war often depended upon close collaboration among alliance partners.
Have you ever wondered how successful Hitler's codebreakers were at breaking Allied codes during World War 2? The wartime story of codebreaking has almost exclusively centred around Allied successes, particularly that of Bletchley Park breaking the Enigma code. However, the Germans in particular were extremely active in codebreaking and had their successes. But it was not until after the war that the extent or otherwise of their triumphs could be gauged. With the war in Europe at an end, in April-May 1945 British and American codebreaking teams hunted for their German counterparts to find out just how good they had been. There were lessons to be learned for the post-war period for Western military intelligence. This publication is a summary of the European Axis Signal Intelligence in World War II as revealed by 'TICOM' Investigations and by other Prisoner of War Interrogations and Captured Material, Principally German and completed in May 1946. This is available on the National Security Agency website. TICOM - Target Intelligence Committee - was a shadowy Anglo-American organisation set up in October 1944 whose cover name disguised its real purpose - the seeking out in the immediate aftermath of the war of German Sigint staff for interrogation. This edited volume extracts key data from the 1000 pages of the original documents to create a fascinating and technical insight into German cryptography. The book is a technical summary of the TICOM documents using the words of those who collected the data. The complex data was written for military analysis so the Allies could assess Hitler's codebreaking operation during the war. It becomes clear that Hitler's team understood that the Enigma cipher machine had weaknesses and that they had various ingenious machines either developed or under development as the war drew to a close. Lack of resources - and running out of time - put paid to any major operational deployment of this machinery, but underlines the fact that German ingenuity came close to a situation where they would have made Bletchley Park's task almost impossible. Includes a report on the interrogation of 5 leading Germans in Nuremburg, September 1945 regarding signals intelligence. They are: General Jodl, Grand Admiral Donitz, General Field Marshall Keitel, Herr von Ribbentrop and Field Marshall Goering.

In his Foreword, Professor Jones writes 'Mr Collier takes the opportunity to review the contributions of all forms of Intelligence, and the use and misuse that was made of them, in all the major phases of World War II. His task has required very wide reading of the great volume of original documents and derivative literature now available, and I admire the judgement that is evident throughout the book. Within the limits of treating the widest aspects of Intelligence in World War II in a small compass, Mr Collier has told the whole truth, fortunately without it turning out to be very unfavorable; and in the lessons to be drawn from it we indeed have one element of security if properly applied'.Basil Collier throws fresh light on the low priority given to Intelligence between the wars; the tendency of ministers and senior officials to rely less on intelligence reports than their own individual hunches; the failure to foresee the invasion of Norway; why, even with the aid of Enigma it was impossible to turn the scales in Crete, and why the Americans, though privy to some of Japans most closely guarded secrets, allowed the Pearl Harbor attack to take them by surprise.
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.
U.s. Army Signals Intelligence In World War Ii by James L. Gilbert,John Patrick Finnegan Pdf
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 official histories. Now much of the story can be told. To preserve the memory of the Army's role in this intelligence war, the U. S. Army Center of Military History has joined with the History Office, U. S. Army Intelligence and Security Command (INSCOM), to publish this collection of documents on Army signals intelligence in World War II. INSCOM carries on the heritage of the Army's World War II Signal Security Agency, which by breaking the Japanese diplomatic ciphers and military codes helped speed the way of our forces to victory. The 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. Harold W. NelsonCharles F.

The Battle of the Atlantic and Signals Intelligence by David Syrett Pdf
This title was first published in 2002. This book contains the U-boats situations and trends written by the staff of the Admiralty’s Operational Intelligence Centre during the Second World War. Based largely on communications intelligence, the U-boat situations and trends were designed to inform a small number of senior officers and high officials of the latest events and developments in the Allied war against the U-boats. The Battle of the Atlantic and the war against the U-boats was the longest and the most complex naval battle in history. In this huge conflict which sprawled across the oceans of the world the U-boats sank 2,828 Allied merchant ships while the Allies destroyed more than 780 German U-boats. These documents relate on a weekly, and in some cases a daily, basis exactly what the Allies knew concerning the activities of the U-boats during the Battle of the Atlantic.
Reading The Enemy’s Mail: by Major Jeffrey S. Harley Pdf
This thesis traces the development of American radio intelligence at the operational and tactical levels from its beginnings in World War I through the end of World War II. It shows that signals intelligence is useful to the tactical and operational level commander. The study recommends the Army rethink signal intelligence support to the various echelons, primarily through changes to tables of organization and equipment. The thesis covers the initial appearance of radio intelligence units on the battlefields of France in the first world war, identifying specific instances where radio intelligence played a role in a command decision. It also looks at training and doctrine in the period between the two world wars. The thesis also covers the organization, doctrine, and training of radio intelligence units as they prepared for combat. It provides a glimpse into the intelligence support provided to the corps, army, and army group commanders during World War II through examination of actual intercept operations. Where possible the study compares and contrasts German radio intelligence units and operations with their American counterparts.
