For almost four desperate years, from 1939 to mid-1943, the British and American navies fought a savage, losing battle against German submarine wolfpacks. The Allies might never have turned the tide without an intelligence coup. The race to break the German U-boat codes is one of the greatest untold stories of World War II. Kahn expertly brings this tale to life in this newly-updated edition of his classic book. Soon after war broke out, HitlerÕs U-boats began to sever Allied lifelines. In the gray wasteland of the North Atlantic, submarines prowled; at night, the sky lit up with the flames of exploding tankers. To meet the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park. As the Battle of the Atlantic raged, they raced to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of HitlerÕs cipher device, the Enigma. Critical to their success was a series of raids at sea. U-110, captured intact in the mid-Atlantic, yielded the Enigma machine itself and also a trove of secret documents. The weather ship Lauenburg seized near the Arctic ice pack provided codesettings for an entire month. In the Mediterranean, two sailors rescued a German weather cipher than enabled the team at Bletchley to solve the Enigma after a year-long blackout.

The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.

Spies, secret messages, and military intelligence have fascinated readers for centuries but never more than today, when terrorists threaten America and society depends so heavily on communications. Much of what was known about communications intelligence came first from David Kahn's pathbreaking book, The Codebreakers. Kahn, considered the dean of intelligence historians, is also the author of Hitler’s Spies: German Military Intelligence in World War II and Seizing the Enigma: The Race to Break the German U-Boat Codes, 1939-1943, among other books and articles. Kahn’s latest book, How I Discovered World War II's Greatest Spy and Other Stories of Intelligence and Code, provides insights into the dark realm of intelligence and code that will fascinate cryptologists, intelligence personnel, and the millions interested in military history, espionage, and global affairs. It opens with Kahn telling how he discovered the identity of the man who sold key information about Germany’s Enigma machine during World War II that enabled Polish and then British codebreakers to read secret messages. Next Kahn addresses the question often asked about Pearl Harbor: since we were breaking Japan’s codes, did President Roosevelt know that Japan was going to attack and let it happen to bring a reluctant nation into the war? Kahn looks into why Nazi Germany’s totalitarian intelligence was so poor, offers a theory of intelligence, explicates what Clausewitz said about intelligence, tells—on the basis of an interview with a head of Soviet codebreaking—something about Soviet Comint in the Cold War, and reveals how the Allies suppressed the second greatest secret of WWII. Providing an inside look into the efforts to gather and exploit intelligence during the past century, this book presents powerful ideas that can help guide present and future intelligence efforts. Though stories of WWII spying and codebreaking may seem worlds apart from social media security, computer viruses, and Internet surveillance, this book offers timeless lessons that may help today’s leaders avoid making the same mistakes that have helped bring at least one global power to its knees. The book includes a Foreword written by Bruce Schneier.

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.

According to Winston Churchill, Alan Turing made the single biggest contribution to the Allied victory over Nazi Germany with his code-breaking machine. The world is also indebted to Turing's genius for the modern computer. It was clear that Turing had a remarkable mind from an early age. He taught himself to read in just three weeks. At his first school, the headmistress said, 'I have had clever and hardworking boys, but Alan has genius.' In 1954, he was found dead, poisoned by an apple laced with cyanide. This is the story of his life.

The brilliant work carried out by British codebreakers based at Bletchley Park is now believed to have shortened the duration of the Second World War by up to two years. But during the dark days of 1941, as Britain stood almost alone against the apparently unstoppable tide of the Nazi war machine, this remarkable achievement seemed a million miles away. With the help of their Polish counterparts, the British codebreakers had broken the German Enigma machine cipher. But the resources on which they could call were so small that it seemed their achievements would be in vain. Without the necessary manpower, they would never be able to take full advantage of their ability to break the German codes and ciphers. In October 1941, four of the leading codebreakers, including the outstanding Alan Turing, wrote a letter to Winston Churchill asking for help. Reminding him that on a recent visit to Bletchley Park he had praised their work, they told him that it was being held up and in some cases not being done at all, principally because we cannot get sufficient staff to deal with it.o Churchill insisted that they be given everything they needed, adding the succinct instruction: 'Action This Day'. It was to be a key turning point for the codebreakers, if not for the war itself. To mark the 60th anniversary of Churchill's 'Action This Day', Michael Smith and Ralph Erskine, both leading authorities on the work of Bletchley Park, have assembled a number of key writers to explain its importance in the history of 20th century codebreaking and the birth of today's computer age. The authors include several of those who worked at Bletchley Park, some of whom have only now agreed to tell their stories, as well as a number of prominent experts on various aspects of the codebreakers' extraordinary achievements. The contributors and editors have donated their royalties from the publication of this book to the Bletchley Park Trust, originally set up to commemorate the codebreakers' work. Their remarkable stories make for compulsive reading.

“Little can be found on the foreign units that were an integral part of the French army ... For a long time a gap has existed, but now Napoleon’s Mercenaries fills this gap.” Robert Burnham, Napoleonic Series. This superb and comprehensive book details the foreign units which formed such an important part of Napoleon's forces. It examines each non-French unit in turn, giving an overview of the unit's origins, its organizational and combat history, its uniforms and standards, and details of the unit's eventual fate. Colourful accounts, taken from contemporary reports and memoirs, emphasize the qualities of the unit and throw light on what life was like for many of the foreign soldiers recruited into the Grande Armée. In total more than 100 different foreign units that served in the French Army are investigated in detail in this ambitious publication. Some foreign units fought and flourished throughout the Consulate and Empire, whilst others lasted for just a few months. Covers Polish, German, Swiss, Italian, Spanish, and other units in the French Army and presents a combat history and details uniforms for each regiment. Napoleon's Mercenaries is the best single-volume study of this aspect of Napoleon’s army and a vital reference for every Napoleonic enthusiast.
