THE story of Bletchley Park’s codebreaking operations in the Second World War is now well known, but its counterparts in the First World War – Room 40 & MI1(b) – remain in the shadows, despite their involvement in and influence on most of the major events of that war. From the First Battle of the Marne, the shelling of Scarborough, the battles of Jutland and the Somme in 1916, to the battles on the Western Front in 1918, the German naval mutiny and the Zimmermann Telegram, this cast of characters – several of them as eccentric as anyone from Bletchley Park in the Second World War – secretly guided the outcome of the ‘Great War’ from the confines of a few smoke-filled rooms. Using hundreds of intercepted and decrypted German military, naval and diplomatic messages, bestselling author Paul Gannon reveals the fascinating story of British codebreaking operations. By drawing on many newly discovered archival documents that challenge misleading stories about Room 40 & MI1(b), he reveals a sophisticated machine in operation.

This is the last untold story of Bletchley Park. Using declassified information, Paul Gannon gives us a gripping account of the invention of the world's first true computer, Colossus. Uncover the secrets of Bletchley Park's code-breaking computers. In 1940, almost a year after the outbreak of the Second World war, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation Bletchley Park codebreakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these codebreakers didn't realize was that they had to fashion the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park. 'Gannon's book contains a mass of utterly fascinating and largely unknown material about an immensely important wartime project, and is very welcome indeed.' - Brian Rendell, TES

Bletchley Park was where one of the war’s most famous – and crucial – achievements was made: the cracking of Germany’s “Enigma” code in which its most important military communications were couched. This country house in the Buckinghamshire countryside was home to Britain’s most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology – indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction – from Robert Harris and Ian McEwan to Andrew Hodges’ biography of Turing – what of the thousands of men and women who lived and worked there during the war? What was life like for them – an odd, secret territory between the civilian and the military? Sinclair McKay’s book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties – of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) – of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels – and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other’s work.

Imagine a Britain where the most important sites of historical significance are replaced with housing estates and supermarkets... Imagine a Britain without Bletchley Park, where Alan Turing and a team of code breakers changed the course of World War II and where thousands of women inspired future generations with their work in the fields of computing and technology... Now imagine a group of extraordinary people, who – seventy years after the birth of the modern computer at Bletchley Park – used technology to spark a social media campaign that helped secure its future and transform it into the world-class heritage and education centre it deserves to be. This is a story about saving Bletchley Park. But it is also the story of the hundreds of people who dedicated twenty years of hard work and determination to the campaign that saved it. It is a testament to the remarkable and mysterious work during World War II that made it a place worth saving. It is a book about campaigners, veterans, enthusiasts, computer geeks, technology, Twitter, trees and Stephen Fry stuck in a lift. And finally, it is a story about preserving the past for the generations of tomorrow.

The World War II codebreaking station at Bletchley is well known and its activities documented in detail. Its decryption capabilities were vital to the war effort, significantly aiding Allied victory. But where did the messages being deciphered come from in the first place? This is the extraordinary untold story of the Y-Service, a secret even more closely guarded than Bletchley Park. The Y-Service was the code for the chain of wireless intercept stations around Britain and all over the world. Hundreds of wireless operators, many of them who were civilians, listened to German, Italian and Japanese radio networks and meticulously logged everything they heard. Some messages were then used tactically but most were sent on to Station X – Bletchley Park – where they were deciphered, translated and consolidated to build a comprehensive overview of the enemy’s movements and intentions. Peter Hore delves into the fascinating history of the Y-service, with particular reference to the girls of the Women’s Royal Naval Service: Wrens who escaped from Singapore to Colombo as the war raged, only to be torpedoed in the Atlantic on their way back to Britain; the woman who had a devastatingly true premonition that disaster would strike on her way to Gibraltar; the Australian who went from being captain of the English Women’s Cricket team to a WWII Wren to the head of Abbotleigh girls school in Sydney; how the Y-service helped to hunt the German battleship Bismarck in the North Atlantic, and how it helped to torpedo a Japanese cruiser in the Indian Ocean. Together, these incredible stories build a picture of World War II as it has never been viewed before.

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.

A fascinating anthology which sheds new light on the Bletchley Park story and shows that there is still more to tell.' - Tony Comer OBE, formerly Departmental Historian at GCHQ This important volume tells the story of Bletchley Park through countless letters written by key players to former colleagues and loved ones as the war unfolded. Having intercepted millions of German communications, the codebreakers had felt bound by the Official Secrets Act and said little about their wartime activities. Some who had stayed on at GCHQ after the war, were concerned that speaking out could jeopardise their pensions.Over one hundred letters have been included in this volume and have either been recovered from family members or declassified by GCHQ. They reveal fresh information about the clandestine operation and disclose the true feelings of the participants at Bletchley.Park. In contrast to early accounts, which lacked detail and were occasionally inaccurate, this book thoroughly lays bare the day-to-day experiences at Bletchley Park and uncovers the operational and technical reasons behind the organisation's successes and failures. Simultaneously intimate and comprehensive, it will interest historians, World War II researchers, and anyone who wants to learn the secrets of Britain's signal intelligence effort.
