With exclusive interviews, a Signal Corps veteran tells the full story of how cryptography helped defeat the Axis powers, at Bletchley Park and beyond. For years, the story of the World War II codebreakers was kept a crucial state secret. Even Winston Churchill, himself a great advocate of Britain’s cryptologic program, purposefully minimized their achievements in his history books. Now, though, after decades have passed, the true scope of the British and American cryptographers’ role in the war has come to light. It was a role key to the Allied victory. From the Battle of Britain to the Pacific front to the panzer divisions in Africa, superior cryptography gave the Allies a decisive advantage over the Axis generals. Military intelligence made a significant difference in battle after battle. In Codebreakers’ Victory, veteran cryptographer Hervie Haufler takes readers behind the scenes in this fascinating underground world of ciphers and decoders. This broad view represents the first comprehensive account of codebreaking during World War II. Haufler pulls together years of research, exclusive access to top secret files, and personal interviews to craft a captivating must-read for anyone interested in the behind-the-front intellect and perseverance that went into beating the Nazis and Japan.

A million pages of new World War II codebreaking records have been released by the U.S. Army and Navy and the British government over the last five years. Now, Battle of Wits presents the history of the war that these documents reveal. From the Battle of Midway until the last German code was broken in January 1945, this is an astonishing epic of a war that was won not simply by brute strength but also by reading the enemy's intentions. The revelations of Stephen Budiansky's dramatic history include how Britain tried to manipulate the American codebreakers and monopolize German Enigma code communications; the first detailed published explanations of how the Japanese codes were broken; and how the American codebreaking machines worked to crack the Japanese, the German, and even the Russian diplomatic codes. This is the story of the Allied codebreakers puzzling through the most difficult codebreaking problems that ever existed. At the same time, the compelling narrative shows the crucial effect codebreaking had on the battle-fields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the burning desire in the United States to turn the tide of the war after Pearl Harbor, the importance of halting Rommel's tanks in North Africa, and the necessity of ensuring that the Germans believed the Allies' audacious deception and cover plans for D-Day. Budiansky brings to life the unsung code-breaking heroes of this secret war: Joseph J. Rochefort, an intense and driven naval officer who ran the codebreaking operation in "The Dungeon", a dank basement at Pearl Harbor, that effectively won the Battle of Midway; Alan Turing, the eccentric father of the computerage, whose brilliant electromechanical calculators broke the German Enigma machine; and Ian Fleming, whose daredevil espionage schemes to recover codebooks resembled the plots of the 007 novels he later wrote. Among the villains, we meet the Nazi Admiral Donitz, who led the submarine wolf packs against Allied shipping in the North Atlantic with horrific casualty rates -- until the codebreakers stopped him. Budiansky, a Harvard-trained mathematician, demonstrates the mathematical insight and creativity of the cryptographers by showing step-by-step precisely how the codes were broken. This technology -- the flow of information, its encryption, and the computational methods of recovering it from the enemy -- had never before been so important to the outcome of a war. Informative diagrams, maps, appendices, and photographs show exactly how, why, and where the secret war was won. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

The thrilling true story of the daring double agents who thwarted Hitler’s spy machine in Britain and turned the tide of World War II. After the fall of France in the mid-1940s, Adolf Hitler faced a British Empire that refused to negotiate for peace. With total war looming, he ordered the Abwehr, Germany’s defense and intelligence organization, to carry out Operation Lena—a program to place information-gathering spies within Britain. Quickly, a network of secret agents spread within the United Kingdom and across the British Empire. A master of disguises, a professional safecracker, a scrubwoman, a diplomat’s daughter—they all reported news of the Allied defenses and strategies back to their German spymasters. One Yugoslav playboy codenamed “Tricycle” infiltrated the highest echelon of British society and is said to have been one of Ian Fleming’s models for James Bond. The stunning truth, though, was that every last one of these German spies had been captured and turned by the British. As double agents, they sent a canny mix of truth and misinformation back to Hitler, all carefully controlled by the Allies. As one British report put it: “By means of the double agent system, we actually ran and controlled the German espionage system in this country.” In The Spies Who Never Were, World War II veteran cryptographer Hervie Haufler reveals the real stories of these double agents and their deceptions. This “fascinating account” lays out both the worldwide machinations and the personal clashes that went into the greatest deception in the history of warfare (Booklist).

This unique reference presents 59 biographies of people who were key to the sea services being reasonably prepared to fight the Japanese Empire when the Second World War broke out, and whose advanced work proved crucial. These intelligence pioneers invented techniques, procedures, and equipment from scratch, not only allowing the United States to hold its own in the Pacific despite the loss of most of its Fleet at Pearl Harbor, but also laying the foundation of today’s intelligence methods and agencies. One-hundred years ago, in what was clearly an unsophisticated pre-information era, naval intelligence (and foreign intelligence in general) existed in rudimentary forms almost incomprehensible to us today. Founded in 1882, the U.S. Office of Naval Intelligence (ONI)—the modern world’s “oldest continuously operating intelligence agency”—functioned for at least its first forty years with low manning, small budgets, low priority, and no prestige. The navy’s early steps into communications intelligence (COMINT), which included activities such as radio interception, radio traffic analysis, and cryptology, came with the 1916 establishment of the Code and Signals Section within the navy’s Division of Communications and with the 1924 creation of the “Research Desk” as part of the Section. Like ONI, this COMINT organization suffered from low budgets, manning, priority, and prestige. The dictionary focuses on these pioneers, many of whom went on, even after World War II, to important positions in the Navy, the State Department, the Armed Forces Security Agency, the National Security Agency, and the Central Intelligence Agency. It reveals the work and innovations of well and lesser-known individuals who created the foundations of today’s intelligence apparatus and analysis.

In the waning days of World War II, a little-known battle took place under the frozen seas off the coast of Norway . . . and changed the course of the war. In February of 1944, Germany and Japan devised a desperate plan to escape defeat. The Germans would send Japan a submarine—boat U-864—packed with their most advanced rocket and jet aircraft technology. Japan could then reestablish air superiority in the Pacific, drawing the attention of Allied forces long enough for Germany to regroup. Meanwhile, British code breakers, working with the Norwegian underground, had discovered the plan. But even though they were unable to stop the submarine from embarking, the British submarine HMS Venturer was waiting for it at sea. In a cat-and-mouse battle beneath the waves, they hunted one another, each waiting to strike. The Venturer won the game, becoming the only submarine in history to sink another sub in underwater combat. This is the dramatic, action-packed account of one of the greatest unsung victories in military history, and of a historical moment in the annals of naval warfare.

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.
