Available in PDF, EPUB and Kindle. Book excerpt: "After World War I, German admirals were shocked to discover that the Royal Navy had penetrated their secret radio codes and the new, post-war navy set about creating a system so secure that such a breach would never occur again. The result was the now famous Enigma - the Impenetrable Puzzle. This machine was so complex that it was thought no one could break into it; not even when they had a captured machine at their disposal. The German High Command was convinced that the system was wholly secure and totally impregnable." "Their supreme confidence was, however, misplaced. During World War Two, Polish cryptanalysts helped Britain to break into the Enigma system used by the Luftwaffe and Army, but the naval version was more complicated. Even so, British cryptanalysts persevered and in the end they did manage the impossible; to break into this most complicated of ciphers. As a result they helped many merchant convoys avoid the teeth of the Wolf Packs." "This book describes the story of how the tools for this incredible effort were extracted from the U-boats themselves. With a detailed analysis of the development of Enigma, its role during U-boat operations and the subsequent code-breaking at Bletchley Park, this book will be essential for all those fascinated by this enigmatic tool." --Book Jacket.

Available in PDF, EPUB and Kindle. Book excerpt: After World War I, the German admirals were shocked to discover that the Royal Navy had had an immense advantage--they had penetrated the secret German radio codes. Confronted with this fact, the Germans determined that any future codes would need to be so complex that breaking them would, theoretically, be impossible. The result was the famous Enigma machine, whose settings were altered so frequently and variables so great that the Germans believed capture of a machine by the enemy would not compromise Enigma for long. But the British proved them wrong. They managed to obtain the machine and determine the method of setting the code, giving the Allies a critical tactical advantage. As the author points out, this intelligence triumph was particularly important during the Battle of the Atlantic, when Hitler's U-boat wolf-packs were wreaking havoc on the convoy lifelines to the British Isles. Without the decoded Enigma messages, the Allies' narrow victory would likely have turned to defeat. This skillful analysis of Enigma's development and its role during U-boat operations includes details of Allied boardings of U-boats from which Enigma machines could have been captured. It is one of the greatest espionage stories in the history of naval warfare.
Download or read book Ultra Versus U Boats written by Roy Conyers Nesbit and published by Casemate Publishers. This book was released on 2009-04-17 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keeping the Atlantic sea-lanes open was a vital factor in the fight against Nazi Germany. In the battle to protect merchant shipping from the menace of surface raiders and U-boats, Allied resolve and resources were tested to the utmost. The story of the extraordinary measures that were taken to combat the threat, at sea and in the air, has often been told. But there is one crucial element in this prolonged campaign that has still not been fully appreciated the role of code-breaking, in particular the decryption of secret signals transmitted by German Enigma machines. And this is the focus of Roy Nesbits fascinating new account of the Battle of the Atlantic. Using previously unpublished decrypts of U-boat signals, selected from the National Archives, along with historic wartime photographs, he tells the stories of the individual U-boats and describes their fate. Their terse signals reveal, perhaps move vividly than conventional communications could do, the desperate plight of the U-boatmen as they struggled against increasingly effective Allied countermeasures that eventually overwhelmed them.

Book excerpt: “An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).
Download or read book The Real Enigma Heroes written by Phil Shanahan and published by The History Press. This book was released on 2017-10-25 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: For almost sixty years after their deaths, three men, whose brave actions shortened the Second World War by as much as two years, remained virtually unknown and uncelebrated. Two lost their lives retrieving vital German codebooks from a sinking U-boat. The third survived the war, only to die in a house fire soon afterwards. But it was the precious documents they seized in October 1942 that enabled Bletchley Park's code-breakers to crack Enigma and so win the Battle of the Atlantic. Now recognised as a pivotal moment in world history, three British servicemen made it possible to finally beat the U-boats, but at the time not even their families could be told of the importance of their deeds. Shrouded in secrecy for decades, then recast as fictional Americans by the Hollywood film U-571, this book sets the record straight. It is written in celebration of Colin Grazier GC, Tony Fasson GC, and Tommy Brown GM - the REAL Enigma heroes.

Available in PDF, EPUB and Kindle. Book excerpt: From January to July 1942, more than seventy-five ships sank to North Carolina's "Graveyard of the Atlantic" off the coast of the Outer Banks. German U-boats sank ships in some of the most harrowing sea fighting close to America's shore. Germany's Operation Drumbeat, led by Admiral Karl Donitz, brought fear to the local communities. A Standard oil tanker sank just sixty miles from Cape Hatteras. The U-85 was the first U-boat sunk by American surface forces, and local divers later discovered a rare Enigma machine aboard. Author Jim Bunch traces the destructive history of world war on the shores of the Outer Banks.

Available in PDF, EPUB and Kindle. Book excerpt: For the first time, the inside story of the brilliant American engineer who defeated Enigma and the Nazi code-masters Much has been written about the success of the British “Ultra” program in cracking the Germans’ Enigma code early in World War II, but few know what really happened in 1942, when the Germans added a fourth rotor to the machine that created the already challenging naval code and plunged Allied intelligence into darkness. Enter one Joe Desch, an unassuming but brilliant engineer at the National Cash Register Company in Dayton, Ohio, who was given the task of creating a machine to break the new Enigma settings. It was an enterprise that rivaled the Manhattan Project for secrecy and complexity–and nearly drove Desch to a breakdown. Under enormous pressure, he succeeded in creating a 5,000-pound electromechanical monster known as the Desch Bombe, which helped turn the tide in the Battle of the Atlantic–but not before a disgruntled co-worker attempted to leak information about the machine to the Nazis. After toiling anonymously–it even took his daughter years to learn of his accomplishments–Desch was awarded the National Medal of Merit, the country’s highest civilian honor. In The Secret in Building 26, the entire thrilling story of the final triumph over Enigma is finally told.
Download or read book Solving the Enigma History of the Cryptanalytic Bombe written by Jennifer Wilcox and published by CreateSpace. This book was released on 2012-08-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the German military grew in the late 1920s, it began looking for a better way to secure its communications. It found the answer in a new cryptographic machine called "Enigma." The Germans believe the encryption generated by the machine to be unbreakable. With a theoretical number of ciphering possibilities of 3 x 10114 their belief was not unjustified. However, they never reached that theoretical level of security. Nor did they count on the cryptanalytic abilities of their adversaries. This publication provides a history of this cryptanalytic bombe.
Download or read book The Capture of U 505 written by Mark Lardas and published by Bloomsbury Publishing. This book was released on 2022-11-24 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: U-505 was the first enemy warship the US Navy captured at sea since 1812. This is a new account of how Captain Gallery planned and executed the raid on his own initiative, and how his success almost endangered the war against the U-boats. On June 4, 1944 a US Navy antisubmarine task group in the Atlantic captured an enemy U-boat on the high seas. It was not the first time the Allies had taken a German U-boat as a prize, but the capture of U-505 was different. Captain Gallery and his Task Group 22.3 devised a risky plan to capture scuttled U-boats. This book analyses in detail Gallery's dangerous strategy, using contemporary sources to explore why he thought the reward was worth the risk: instead of attempting to sink the next U-boat that surfaced among them, a destroyer escort would send off its whaleboat. Everyone else was to smother the U-boat with light gunfire to encourage its crew to abandon quickly. Unaware that the Allies had already cracked the German's codes and the capture of a U-boat could endanger that secret, Gallery hoped to capture the vessel's codes and coding equipment to read U-boat message traffic. The plan culminated in the capture of U-505 in early June, which nearly caused the exposure of the Bletchley Park codebreaking secret. Featuring contemporary photographs, specially commissioned artwork and 3D maps, this book is a fascinating exploration of one of the most controversial and dangerous raids, which could have changed the outcome of World War II as we know it.
Download or read book Seizing the Enigma written by David Kahn and published by . This book was released on 2012-02-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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, Hitler's 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 Hitler's 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.

Available in PDF, EPUB and Kindle. Book excerpt: Osprey's elite title on Germany's U-Boat tactics during World War II (1939-1945). At the start of the war, German U-boat technology vastly out performed that possessed by the Allies, and under the pressure of the war continual development helped keep pace with wartime needs and improvements in anti-submarine weaponry. But it was not just the technology that had to change. German U-boat tactics evolved over time. Used in a variety of roles, from coastal patrolling through to the combined actions of convey-hunting 'wolf packs', the tactics used by U-Boats were diverse. This book analyses how the U-boats dominated the seas thanks to their innovative and daring tactical deployment, and how the cracking of the Enigma code effectively hamstrung them, greatly reducing their impact, a problem that even their advanced tactics failed to solve.
