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.

In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities of reading and deciphering diplomatic, military and commercial communications of other nations. This work reveals the role of intercepting messages during the Cold War.

From the ancient Greek and Roman origins of human intelligence and its use in the Catholic church to Francis Walsingham's Elizabethan secret service to the birth of the surveillance state in today's digital hi-tech age, Colonel John Hughes-Wilson, author of the highly successful Military Intelligence Blunders, gives an extraordinarily broad and wide-reaching perspective on espionage and intelligence, providing an up-to-date analysis of its importance of intelligence and in the recent past. Drawing upon a variety of sources, ranging from first-hand accounts to his own personal experience, Hughes-Wilson covers everything from undercover agents to photographic reconnaissance to today's much misunderstood cyber welfare.Authoritative and analytical, Hughes-Wilson searches for hard answers and scrutinizes why crucial intelligence is so often ignored, misunderstood, or spun by politicians and seasoned generals alike. From yesterday's spies to tomorrow's cyber world, The Secret State is a fascinating and thought­-provoking history of this ever­-changing and ever­-important subject.

The National Security Agency is the world’s most powerful, most far-reaching espionage. Now with a new afterword describing the security lapses that preceded the attacks of September 11, 2001, Body of Secrets takes us to the inner sanctum of America’s spy world. In the follow-up to his bestselling Puzzle Palace, James Banford reveals the NSA’s hidden role in the most volatile world events of the past, and its desperate scramble to meet the frightening challenges of today and tomorrow. Here is a scrupulously documented account—much of which is based on unprecedented access to previously undisclosed documents—of the agency’s tireless hunt for intelligence on enemies and allies alike. Body of secrets is a riveting analysis of this most clandestine of agencies, a major work of history and investigative journalism. A New York Times Notable Book

While written under the auspices of the Trustees of the Military Intelligence Museum, Sharing the Secret is not an academic regimental history. Rather it gives a privileged glimpse into a necessarily publicity-shy organization that has been deeply involved in military intelligence operations since its inception in 1940 through to 2010. Understandably, little has been written about the Corps' work for Official Secret reasons.The development of Field Security and Protective Security and measures taken to protect the Army for espionage, sabotage, subversion and terrorism in peace and war are examined. These tasks were particularly important during the de-Nazification of Germany during the aftermath of the Second World War. Field Security led to the successful arrest of leading Nazis, including Himmler and Doenitz.The author, who served in the Corps for over 20 years and saw active service in Northern Ireland and the Falklands, gives fascinating examples of differing Intelligence techniques in action. These include the exploitation of Imagery Interpretation, Human Intelligence, including the interrogation of prisoners of war, the examination of enemy documents and the deployment of Signals Intelligence so that commanders have enough information to fight the battles. The support the Intelligence Corps gave to the Special Operations Executive during the Second World War is well covered, as are examples of Special Duties since 1945.The reader will appreciate that, as with any work relating to national intelligence and security, Sharing the Secret has been written under the restrictions of the era. That said, it provides a long-overdue insight into the contribution of members of the Intelligence Corps over seventy years of war and peace.As featured in Burnham & Highbridge News
