The Secret History of Signals Intelligence in the World Wars
By Peter Matthews
!!!! BACK IN STOCK AS A PAPERBACK !!!!
This great and extremely popular book is now available as a paperback. Signals Intelligence, or SIGINT, is the interception and evaluation of coded enemy messages. Written by acknowledged expert Peter Mathews this book 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.
From ENIGMA to ULTRA, PURPLE to LORENZ, Room 40 to Bletchley, SIGINT has been instrumental in both victory and defeat during both the First and Second World War. During 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. SIGINT even provides a fascinating account of what Allied investigators learned post war about the Nazi equivalent of Bletchley Park.
Including material from declassified NSA documents, SIGINT provides an insight into the work of this shadowy organisation and its achievements. If you are interested in Enigma, Bletchley or the work of Room 40 this book is recommended reading
