Lorenz PDF Author: Jerry Roberts
Publisher: The History Press
ISBN: 0750982047
Category : Biography & Autobiography
Languages : en
Pages : 300

Book Description
The breaking of the Enigma machine is one of the most heroic stories of the Second World War and highlights the crucial work of the codebreakers of Bletchley Park, which prevented Britain's certain defeat in 1941. But there was another German cipher machine, used by Hitler himself to convey messages to his top generals in the field. A machine more complex and secure than Enigma. A machine that could never be broken. For sixty years, no one knew about Lorenz or 'Tunny', or the determined group of men who finally broke the code and thus changed the course of the war. Many of them went to their deaths without anyone knowing of their achievements. Here, for the first time, senior codebreaker Captain Jerry Roberts tells the complete story of this extraordinary feat of intellect and of his struggle to get his wartime colleagues the recognition they deserve. The work carried out at Bletchley Park during the war to partially automate the process of breaking Lorenz, which had previously been done entirely by hand, was groundbreaking and is recognised as having kick-started the modern computer age.

Book Description
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.

Book Description
Unbreakable is the edge-of-your seat true story of the codebreakers, spies, and navy fighters who helped defeat the Nazis and turned the tide of World War II—perfect for fans of The Imitation Game, Alan Gratz, and Jennifer Nielsen. "A thrilling adventure of intrigue and daring worthy of the best James Bond stories." —James Ponti, New York Times best-selling author of City Spies As the Germans waged a brutal war across Europe, details of every Nazi plan, every attack, every troop movement were sent over radio. But to the Allied troops listening in—and they were always listening—the crucial messages sounded like gibberish. The communications were encoded with a powerful cipher, making all information utterly inaccessible . . . unless you could unlock the key to the secret code behind the German’s powerful Enigma machine. Complete with more than sixty historical photos, Unbreakable tells the true story of one of the most dangerous war-time codebreaking efforts ever. While Hitler marched his troops across newly conquered lands and deadly “wolfpacks” of German U-Boats prowled the open seas, a team of codebreakers, spies, and navy men raced against the clock to uncover the secrets that hid German messages in plain sight. Victory—or defeat—in World War II would hinge on their desperate attempts to crack the code. Perfect for fans of Bomb, The Boys Who Challenged Hitler, and The Nazi Hunters.

Languages : en
Pages : 283

Book Description
A fascinating exploration of the uncrackable codes and secret cyphers that helped win wars, spark revolutions and change the faces of nations. There have been secret codes since before the Old Testament, and there were secret codes in the Old Testament, too. Almost as soon as writing was invented, so too were the devious means to hide messages and keep them under the wraps of secrecy. In The Hidden History of Code Breaking, Sinclair McKay explores these uncrackable codes, secret ciphers, and hidden messages from across time to tell a new history of a secret world. From the temples of Ancient Greece to the court of Elizabeth I; from antique manuscripts whose codes might hold prophecies of doom to the modern realm of quantum mechanics, we will see how a few concealed words could help to win wars, spark revolutions and even change the faces of great nations. Here is the complete guide to the hidden world of codebreaking, with opportunities for you to see if you could have cracked some of the trickiest puzzles and lip-chewing codes ever created.

Hitler's Codebreakers

Hitler's Codebreakers PDF Author: John Jackson
Publisher: Booktowerpublishing
ISBN: 9780955716447
Category : World War, 1939-1945
Languages : en
Pages : 228

Book Description
Have you ever wondered how successful Hitler's codebreakers were at breaking Allied codes during World War 2? The wartime story of codebreaking has almost exclusively centred around Allied successes, particularly that of Bletchley Park breaking the Enigma code. However, the Germans in particular were extremely active in codebreaking and had their successes. But it was not until after the war that the extent or otherwise of their triumphs could be gauged. With the war in Europe at an end, in April-May 1945 British and American codebreaking teams hunted for their German counterparts to find out just how good they had been. There were lessons to be learned for the post-war period for Western military intelligence. This publication is a summary of the European Axis Signal Intelligence in World War II as revealed by 'TICOM' Investigations and by other Prisoner of War Interrogations and Captured Material, Principally German and completed in May 1946. This is available on the National Security Agency website. TICOM - Target Intelligence Committee - was a shadowy Anglo-American organisation set up in October 1944 whose cover name disguised its real purpose - the seeking out in the immediate aftermath of the war of German Sigint staff for interrogation. This edited volume extracts key data from the 1000 pages of the original documents to create a fascinating and technical insight into German cryptography. The book is a technical summary of the TICOM documents using the words of those who collected the data. The complex data was written for military analysis so the Allies could assess Hitler's codebreaking operation during the war. It becomes clear that Hitler's team understood that the Enigma cipher machine had weaknesses and that they had various ingenious machines either developed or under development as the war drew to a close. Lack of resources - and running out of time - put paid to any major operational deployment of this machinery, but underlines the fact that German ingenuity came close to a situation where they would have made Bletchley Park's task almost impossible. Includes a report on the interrogation of 5 leading Germans in Nuremburg, September 1945 regarding signals intelligence. They are: General Jodl, Grand Admiral Donitz, General Field Marshall Keitel, Herr von Ribbentrop and Field Marshall Goering.

Hitler's War Beneath the Waves

Hitler's War Beneath the Waves PDF Author: Michael FitzGerald
Publisher: Arcturus Publishing
ISBN: 183940387X
Category : History
Languages : en
Pages : 282

Book Description
At the beginning of World War II, the devastating impact of German submarines on both the Royal Navy and merchant shipping saw Britain on the brink of starvation and defeat. The enemy was formidable. U-boat crews saw themselves as an elite and they preferred to scuttle their vessels at the end of the war rather than surrender. They suffered the heaviest losses of any branch of the German services: out of 40,900 men, 28,000 were killed and 5,000 taken prisoner; by 1945, the average age was 19 and the survival rate was only three missions. This is the story of how the Allies redressed the balance of power, focusing in particular on the role of the wolfpacks of U-boats in the Atlantic, whose stealthy presence beneath the waves ensured that British ships diced with death every time they put to sea.

ISBN: 0525521542
Category : History
Languages : en
Pages : 257

Book Description
The dramatic, untold story of the brilliant team whose feats of innovation and engineering created the world’s first digital electronic computer—decrypting the Nazis’ toughest code, helping bring an end to WWII, and ushering in the information age. • Winner, Institute of Electrical and Electronics Engineers Middleton Award for "a book ... that both exemplifies exceptional scholarship and reaches beyond academic communities toward a broad public audience." • A Kirkus Best Book of 2022 • Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher. To surmount this seemingly impossible challenge, Alan Turing, the Enigma codebreaker, brought in a maverick English working-class engineer named Tommy Flowers who devised the ingenious, daring, and controversial plan to build a machine that would calculate at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman, Flowers and his team produced—against the odds, the clock, and a resistant leadership—Colossus, the world’s first digital electronic computer, the machine that would help bring the war to an end. Drawing upon recently declassified sources, David A. Price’s Geniuses at War tells, for the first time, the full mesmerizing story of the great minds behind Colossus and chronicles the remarkable feats of engineering genius that marked the dawn of the digital age.
