“Enigma’s ‘forgotten genius’ . . . [the] story of Alan Turing’s spymaster boss who led the team that cracked Hitler’s WWII codes.” —Daily Mail The Official Secrets Act and the passing of time have prevented the Bletchley Park story from being told by many of its key participants. Here at last is a book that allows some of them to speak for the first time. Gordon Welchman was one of the Park’s most important figures. Like Alan Turing, his pioneering work was fundamental to the success of Bletchley Park and helped pave the way for the birth of the digital age. Yet, his story is largely unknown to many. His book, The Hut Six Story, was the first to reveal not only how they broke the codes, but how it was done on an industrial scale. Its publication created such a stir in GCHQ and the NSA that Welchman was forbidden to discuss the book or his wartime work with the media. In order to finally set the record straight, Bletchley Park historian and tour guide Joel Greenberg has drawn on Welchman’s personal papers and correspondence with wartime colleagues that lay undisturbed in his son’s loft for many years. Packed with fascinating new insights, including Welchman’s thoughts on key Bletchley figures and the development of the bombe machine, this is essential reading for anyone interested in the clandestine activities at Bletchley Park. “A magnificent biography which finally provides recognition to one of Bletchley’s and Britain’s lost heroes.” —Michael Smith “Reveals a man equally as fascinating equally as important as Turing, and tells us even more about what went on in this most secret of establishments during the war years.” —Books Monthly

In 1941, the United Kingdom faced its darkest hour: it stood alone against the Germans, who had chased British forces out of France, Norway, and Greece. All it had left were desperate measures--commando raids, intelligence coups, feats of derring-do. Any such "novel enterprise," wrote Admiral John Godfrey, Director of Naval Intelligence, required "an officer with drive and imagination of the highest order." He found one in Commander Ian Fleming. In Ian Fleming's Commandos, Nicholas Rankin tells the exciting story of a secret intelligence outfit conceived and organized by Fleming. Named 30 Assault Unit, the group was expected to seize enemy codebooks, cipher machines, and documents in high-stakes operations. Assault unit commandos fought in the North African campaign and the invasions of Sicily and Italy, poked over the bones of bombed Pantelleria, and liberated Capri. Rebranded '30 Assault Unit', they went ashore on D-Day, heading for rocket-sites and radar-stations. They helped liberate Paris (including the Ritz Bar and the Rothschild mansion) and then set out to steal scientific and industrial secrets from the heart of Germany. Their final amazing coup was to seize the entire archives of the German Navy's three hundred tons of documents. Ian Fleming flew out in person to accompany the loot back to Britain, where it was combed for evidence to use in the Nuremburg trials. Based on incisive research and written with verve and insight, this new paperback edition of Ian Fleming's Commandos brings to life a long-obscured chapter of World War II and reveals the inspiration behind Fleming's famous fiction.

At last - the secrets of Bletchley Park's powerful codebreaking computers. This is a history of Colossus, the world's first fully-functioning electronic digital computer. Colossus was used during the Second World War at the Government Code and Cypher School at Bletchley Park, where it played an invaluable role cracking enemy codes. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the codes that were employed remained in use by the British security services until a short time ago. This book only became possible due to the declassification in the US of wartime documents. With an introductory essay on cryptography and the history of code-breaking by Simon Singh, this book reveals the workings of Colossus and the extraordinary staff at Bletchley Park through personal accounts by those who lived and worked with the computer. Among them is the testimony of Thomas Flowers, who was the architect of Colossus and whose personal account, written shortly before he died, is published here for the first time. Other essays consider the historical importance of this remarkable machine, and its impact on the generations of computing technology that followed.

Here is the ultimate inside history of twentieth-century intelligence gathering and covert activity. Unrivalled in its scope and as readable as any spy novel, A Century of Spies travels from tsarist Russia and the earliest days of the British Secret Service to the crises and uncertainties of today's post-Cold War world, offering an unsurpassed overview of the role of modern intelligence in every part of the globe. From spies and secret agents to the latest high-tech wizardry in signals and imagery surveillance, it provides fascinating, in-depth coverage of important operations of United States, British, Russian, Israeli, Chinese, German, and French intelligence services, and much more. All the key elements of modern intelligence activity are here. An expert whose books have received high marks from the intelligence and military communities, Jeffrey Richelson covers the crucial role of spy technology from the days of Marconi and the Wright Brothers to today's dazzling array of Space Age satellites, aircraft, and ground stations. He provides vivid portraits of spymasters, spies, and defectors--including Sidney Reilly, Herbert Yardley, Kim Philby, James Angleton, Markus Wolf, Reinhard Gehlen, Vitaly Yurchenko, Jonathan Pollard, and many others. Richelson paints a colorful portrait of World War I's spies and sabateurs, and illuminates the secret maneuvering that helped determine the outcome of the war on land, at sea, and on the diplomatic front; he investigates the enormous importance of intelligence operations in both the European and Pacific theaters in World War II, from the work of Allied and Nazi agents to the "black magic" of U.S. and British code breakers; and he gives us a complete overview of intelligence during the length of the Cold War, from superpower espionage and spy scandals to covert action and secret wars. A final chapter probes the still-evolving role of intelligence work in the new world of disorder and ethnic conflict, from the high-tech wonders of the Gulf War to the surprising involvement of the French government in industrial espionage. Comprehensive, authoritative, and addictively readable, A Century of Spies is filled with new information on a variety of subjects--from the activities of the American Black Chamber in the 1920s to intelligence collection during the Cuban missile crisis to Soviet intelligence and covert action operations. It is an essential volume for anyone interested in military history, espionage and adventure, and world affairs.

'Briggs is an engaging and amiable guide though the mysteries of wartime cryptography . . . a fascinating account of an outstanding young man and his time at a quite remarkable institution.' Roger Moorhouse in BBC History magazine Lord Briggs has long been regarded as one of Britain's most important historians. However, until the publication of this remarkable book, he had never written about his time at Bletchley Park. Briggs himself did not tell his wife about his wartime career until the 1970s and his parents died without ever knowing about their son's contribution to the war effort. In this meticulously researched account he finally reveals the details of his life in Hut Six working as a code breaker alongside Alan Turing and Gordon Welchman. In addition to discussing the progress of the Allies' code breaking efforts and its impact on the war, Lord Briggs considers what the Germans knew about Bletchley and how they reacted to revelatory memoirs about the Enigma machine, which were not published until the 1970s. Packed with fascinating anecdotes, this is the gripping, revelatory story of an extraordinary young man in an extraordinary place.

On 2 August 1944, in the wake of the complete destruction of the German Army Group Centre in Belorussia, Winston Churchill mocked Adolf Hitler in the House of Commons by the rank he had reached in the First World War. 'Russian success has been somewhat aided by the strategy of Herr Hitler, of Corporal Hitler,' Churchill jibed. 'Even military idiots find it difficult not to see some faults in his actions.' Andrew Roberts's previous book Masters and Commanders studied the creation of Allied grand strategy; Beating Corporal Hitler now analyses how Axis strategy evolved. Examining the Second World War on every front, Roberts asks whether, with a different decision-making process and a different strategy, the Axis might even have won. Were those German generals who blamed everything on Hitler after the war correct, or were they merely scapegoating their former Führer once he was safely beyond defending himself? In researching this uniquely vivid history of the Second World War Roberts has walked many of the key battlefield and wartime sites of Russia, France, Italy, Germany and the Far East. The book is full of illuminating sidelights on the principle actors that bring their characters and the ways in which they reached decisions into fresh focus.
