GCHQ is the successor to the famous Bletchley Park wartime code-breaking organisation and is the largest and most secretive intelligence organisation in the country. During the war, it commanded more staff than MI5 and MI6 combined and has produced a number of intelligence triumphs as well as some notable failures. Since the end of the Cold War, it has played a pivotal role in shaping Britain's secret state. Still, we know almost nothing about it. In this fascinating new book, Richard J. Aldrich traces GCHQ's evolvement from a wartime code breaking operation based in the Bedfordshire countryside to one of the world's leading espionage organisations. Focusing in part on GCHQ's remarkably intimate relationship with its American partner, the National Security Agency (NSA), Aldrich also examines both the impact of the Second World War on GCHQ and the breakthroughs made after the war was over. Today's GCHQ struggles with some of the most difficult issues of our time. A leading force of the state's security efforts against militant terrorist organisations like Al-Qaeda, they are also involved in fundamental issues that will mould the future of British society. Compelling and revealing, this is historical writing of the utmost importance.

For a hundred years GCHQ ' Government Communications Headquarters ' has been at the forefront of British secret statecraft. Born out of the need to support military operations in the First World War, and fought over ever since, today it is the UK's biggest intelligence, security and cyber agency and a powerful tool of the British state. Famed primarily for its codebreaking achievements at Bletchley Park against Enigma ciphers in the Second World War, GCHQ has intercepted, interpreted and disrupted the information networks of Britain's foes for a century, and yet it remains the least known and understood of British intelligence services. It has been one of the most open-minded, too: GCHQ has always demanded a diversity of intellectual firepower, finding it in places which strike us as ground-breaking today, and allying it to the efforts of ordinary men and women to achieve extraordinary insights in war, diplomacy and peace. GCHQ shapes British decision-making more than any other intelligence organisation and, along with its partners in the Five Eyes intelligence partnership-including the United States' National Security Agency-has become ever more crucial in an age governed by information technology. Based on unprecedented access to documents in GCHQ's archive, many of them hitherto classified, this is the first book to authoritatively explain the entire history of one of the world's most potent intelligence agencies. Many major contemporary conflicts-between Russia and the West, between Arab nations and Israel, between state security and terrorism-become fully explicable only in the light of the secret intelligence record. Written by one of the world's leading experts in intelligence and strategy, Behind the Enigma reveals the fascinating truth behind this most remarkable and enigmatic of organisations.

The go-to intelligence expert and author of MI6 has “provided the clearest review of GCHQ and its predecessors in a publicly available book” (Firetrench). Signal intelligence is the most secret, and most misunderstood, weapon in the modern espionage arsenal. As a reliable source of information, it is unequalled, which is why Government Communications Headquarters, almost universally known as GCHQ, is several times larger than the two smaller, but more familiar, organizations, MI5 and MI6. Because of its extreme sensitivity, and the ease with which its methods can be compromised, GCHQ’s activities remain cloaked in secrecy. In GCHQ: The Secret Wireless War 1900-1986, the renowned expert Nigel West traces GCHQ’s origins back to the early days of wireless and gives a detailed account of its development since that time. From the moment that Marconi succeeded in transmitting a radio signal across the Channel, Britain has been engaged in a secret wireless war, first against the Kaiser, then Hitler and the Soviet Union. Following painstaking research, Nigel West is able to describe all GCHQ’s disciplines, including direction-finding, interception and traffic analysis, and code-breaking. Also explained is the work of several lesser known units such as the wartime Special Wireless Groups and the top-secret Radio Security Service. Laced with some truly remarkable anecdotes, this edition of this important book will intrigue historians, intelligence professionals and general readers alike. “Nigel West is an acknowledged expert in this field of literature and his latest book is fascinating and intriguing.” —Books Monthly “Rich in the kind of detail from which all students of radio and military history can learn.” —The Spectrum Monitor

Following on from the enormous success of his bestseller, The Secret Life of Bletchley Park, renowned author Sinclair McKay uncovers the story of what happened after the end of the Second World War. Once victory was declared, many of the individuals who had achieved the seemingly impossible at Bletchley Park by cracking the impenetrable Enigma codes and giving the Allies an invaluable insight directly into the Nazi war machine, moved on to GCHQ. This was the British government’s new facility established to fight a different, but no less formidable foe – Stalin and the KGB. Fascinating and insightful revelations from deep within the archives of this secret organisation reveal the story of the tumultuous early years of GCHQ as it navigated its way through an era of double agents, deception and betrayals. From the defection of the Cambridge Five and the treachery of the atomic scientist Klaus Fuchs, to the collapse of the British Empire, the ascension of Chairman Mao and the emergence of the US as a superpower, McKay deftly explores the impact these events had on the fledgling organisation. During the years of the Cold War the men and women of GCHQ penetrated Soviet encryptions and gathered crucial intelligence from all over the world. The Spies of Winter tells the story of the codebreakers themselves and how they used new technology to expand the horizons of cryptography in order to defend the nation and maintain the fragile peace in a world now under the shadow of nuclear holocaust.
