"The lieutenant descended slowly into the quiet and gloom. As he began to step down into the control room, he was gripped by a feeling of dread. Someone could be down there waiting for him..." Hitler's U-boats rule the North Atlantic and threaten to eliminate the Allied forces supply lines through meticulously coordinated attacks using Germany's secret weapon: the Enigma. Desperate to turn the tide of the war, British scientists at Bletchley Park work tirelessly to break the codes. But there is a problem. They need the German ciphers and a working Enigma machine. In this gripping story held secret for years, you'll join the crew of HMS Bulldog as they execute a covert WWII mission to seize a functioning Enigma and the ciphers Britain so desperately needs. The bravery of these sailors saved countless lives and crippled German naval operations, eventually giving the Allied forces the victory needed to win the war and end Hitler's reign of terror.

For fifteen years after the end of the war all official Admiralty records showed the German submarine U 110 as sunk on 9 May 1941 by the surface escorts of convoy OB.318. As this book was the first to reveal, this was a deliberate deception, as the U-boat was actually captured and its contents fully investigated before being allowed to sink a day later, a fact skilfully kept from even the survivors of the submarine's crew. As the official historian of the naval war, Roskill had followed the party line when writing his authorised account, but provoked by exaggerated claims concerning a US Navy capture of a U-boat in 1944, Roskill decided to set the record straight. His narrative is prefaced by brief coverage of previous submarine captures by the Royal Navy - three Italian and one German - before covering the U 110 operation in great detail, underlining the skill and bravery of those involved. We now know that the reason for the secrecy was that the U-boat gave up valuable codebooks, charts, ciphers and, most significantly, a complete and undamaged Enigma machine. At the time of the book's first publication, Ultra was still a secret, so Roskill (who clearly knew about it) had to be discreet about the exact details of what was taken from the submarine while insisting on its crucial value to the war effort. However, a new introduction puts the capture into context, making clear its vital importance in the history of allied codebreaking in World War Two.

“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).

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.

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.

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.

"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.
