Bletchley Park's Secret Source by Peter Hore Pdf

A captivating history of the highly secret group of women who helped win the Second World War. The World War II codebreaking station at Bletchley is well known and its activities documented in detail. Its decryption capabilities were vital to the war effort, significantly aiding Allied victory. But where did the messages being deciphered come from in the first place? This is the extraordinary untold story of the Y-Service, a secret even more closely guarded than Bletchley Park. The Y-Service was the code for the chain of wireless intercept stations around Britain and all over the world. Hundreds of wireless operators, many of them who were civilians, listened to German, Italian and Japanese radio networks and meticulously logged everything they heard. Some messages were then used tactically but most were sent on to Station X—Bletchley Park—where they were deciphered, translated and consolidated to build a comprehensive overview of the enemy’s movements and intentions. Peter Hore delves into the fascinating history of the Y-service, with particular reference to the girls of the Women’s Royal Naval Service: Wrens who escaped from Singapore to Colombo as the war raged, only to be torpedoed in the Atlantic on their way back to Britain; the woman who had a devastatingly true premonition that disaster would strike on her way to Gibraltar; the Australian who went from being captain of the English Women’s Cricket team to a WWII Wren to the head of Abbotleigh girls school in Sydney; how the Y-service helped to hunt the German battleship Bismarck in the North Atlantic, and how it helped to torpedo a Japanese cruiser in the Indian Ocean. Together, these incredible stories build a picture of World War II as it has never been viewed before. “We get to see how the work of individual Wrens helped in such operations as the interception and sinking of the Bismarck, the Slapton Sands disaster, several naval battles (Channel Dash, Matapan, etc.), the ongoing small warship clashes in coastal waters, convoy defense, and more. A good read for anyone interested in the naval side of the war in Europe or in the role of women in military service.” —The NYMAS Review “Will reward a patient reader with a remarkably intimate view into the lives and times of these hidden heroes.” —Naval Historical Foundation

Bletchley Park and D-Day by David Kenyon Pdf

“Demonstrates that the intelligence division . . . had a more significant role in WWII . . . making indispensable contributions to the invasion at Normandy.” (Publishers Weekly) The untold story of Bletchley Park's key role in the success of the Normandy campaign Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis’ codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it. Using previously classified documents, David Kenyon casts the work of Bletchley Park in a new light, as not just a codebreaking establishment, but as a fully developed intelligence agency. He shows how preparations for the war’s turning point—the Normandy Landings in 1944—had started at Bletchley years earlier, in 1942, with the careful collation of information extracted from enemy signals traffic. This account reveals the true character of Bletchley's vital contribution to success in Normandy, and ultimately, Allied victory.

Colossus by Paul Gannon Pdf

In 1940, almost a year after the outbreak of World War II, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, math, innovation, and improvisation, Bletchley Park code breakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these code breakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.

The Enigma Girls: How Ten Teenagers Broke Ciphers, Kept Secrets, and Helped Win World War II (Scholastic Focus) by Candace Fleming Pdf

With numerous starred reviews and accolades, from award-winning author Candace Fleming, comes the powerful and fascinating story of the brave and dedicated young women who helped turn the tides of World War II for the Allies, with their hard work and determination at Bletchley Park. "Events are brought to dramatic life through a treasure trove of photographs--which show the goings-on at Bletchley and the sobering progress of the war--and through the author's meticulous research." -- The New York Times Book Review "You are to report to Station X at Bletchley Park, Buckinghamshire, in four days time....That is all you need to know." This was the terse telegram hundreds of young women throughout the British Isles received in the spring of 1941, as World War II raged. As they arrived at Station X, a sprawling mansion in a state of disrepair surrounded by Spartan-looking huts with little chimneys coughing out thick smoke-these young people had no idea what kind of work they were stepping into. Who had recommended them? Why had they been chosen? Most would never learn all the answers to these questions. Bletchley Park was a well-kept secret during World War II, operating under the code name Station X. The critical work of code-cracking Nazi missives that went on behind its closed doors could determine a victory or loss against Hitler's army. Amidst the brilliant cryptographers, flamboyant debutantes, and absent-minded professors working there, it was teenaged girls who kept Station X running. Some could do advanced math, while others spoke a second language. They ran the unwieldy bombe machines, made sense of wireless sound waves, and sorted the decoded messages. They were expected to excel in their fields and most importantly: know how to keep a secret. Candace Fleming is the award-winning and highly acclaimed author of Crash from Outer Space, The Curse of the Mummy, and many other nonfiction books for young readers. With her canny and compelling narrative voice she makes history come alive. The recipient of five starred reviews, and thick with tension and suspense, The Enigma Girls is an extraordinary and relatively unknown story of World War II that will fascinate readers who will be thrilled to see young people playing such an important role in the wartime effort. Scholastic Focus is the premier home of thoroughly researched, beautifully written, and thoughtfully designed works of narrative nonfiction aimed at middle-grade and young adult readers. These books help readers learn about the world in which they live and develop their critical thinking skills, so that they may become dynamic citizens who are able to analyze and understand our past, participate in essential discussions about our present, and work to grow and build our future. Praise for The Enigma Girls: "Events are brought to dramatic life through a treasure trove of photographs--which show the goings-on at Bletchley and the sobering progress of the war--and through the author's meticulous research." -- The New York Times Book Review * "A thrilling account... Fleming does it again! [T]his compelling blend of WWII, cryptography, and women's history... will mesmerize middle schoolers and inspire them to make an indelible impact on history, too." -- School Library Journal, starred review * "Fleming delivers a fascinating and cohesive overview of Bletchley Park's necessarily siloed, collaborative inner workings that reveals how the figures' ardent efforts affected the outcome of WWII." -- Publishers Weekly, starred review * "In this absorbing book, Fleming approaches the subject by telling the individual stories of 10 young women... who left their homes to work secretly on projects related to the German military's Enigma cipher machine. Even readers with little interest in codes and ciphers will find the women's experiences intriguing." -- Booklist, starred review * "This compulsively readable, compellingly written book will appeal to a broad audience, from readers already interested in World War II to those who are new to the subject." -- Kirkus Reviews, starred review * "[This] is a fascinating and emotionally moving perspective on the well-trod ground of WWII, carefully balanced and rich with details of technology, history, and humanity. This book is not just about deciphering the Enigma messages, however, as it peels back the mythological layers of history to depict the people, technology, mind-numbing mundanity, and heartbreaking tragedy of the war machine." -- The Bulletin of the Center for Children's Books, starred review

Most Secret Source: The Role of Enigma in WWII by Darvin Babiuk Pdf

How did ULTRA shape the course of the war? At times, it played a major role in the turning of battle, at other times did not, at still others was fatally misused, and at still others was beneficial but not necessary to bring about victory in any case. Unfortunately, good intelligence is often badly used by its masters. ULTRA was no different. Did ULTRA win the war? No, men and tanks and bombs and airplanes did. Did ULTRA shorten the war? Given the extent to it which it provided foreknowledge, once the balance of military forces was relatively close the answer must be yes. Did ULTRA prevent an earlier end to the war either by creating such confidence that avoidable mistakes were made in the rush for glory, or by preventing acceptance of an outcome short of unconditional surrender, or by causing the Allies to discount internal German opposition and a possible suicide attempt on Hitler? No, for its benefits outweighed its negative. Does the glory of the victory become tainted in light of ULTRA? Yes, for not only does it reveal the extent to which our commanders knew in advance of German battle strengths and location, thus giving them a decided advantage, it also points out several egregious errors on their part despite possession of ULTRA. Can intelligence be counted on to provide us victory in future conflicts. No. ULTRA use and implementation was clearly deficient for two to three years, and came about only with the help of Polish and French contributions which we cannot count on in the future. As Welchman points out, that may well mean suicide in a world where computers and ICBM's reduce the drag time to seconds from years. What role did ULTRA play? To quote one of the examiners: "Ultra was a war winner" even if not "the war winner."

The Secret Life of Bletchley Park by Sinclair McKay Pdf

Bletchley Park was where one of the war’s most famous – and crucial – achievements was made: the cracking of Germany’s “Enigma” code in which its most important military communications were couched. This country house in the Buckinghamshire countryside was home to Britain’s most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology – indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the boffins, and the codebreaking, fictional and non-fiction – from Robert Harris and Ian McEwan to Andrew Hodges’ biography of Turing – what of the thousands of men and women who lived and worked there during the war? What was life like for them – an odd, secret territory between the civilian and the military? Sinclair McKay’s book is the first history for the general reader of life at Bletchley Park, and an amazing compendium of memories from people now in their eighties – of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in) – of a youthful Roy Jenkins, useless at codebreaking, of the high jinks at nearby accommodation hostels – and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other’s work.

Secret Operations Over Occupied Europe by Nigel S Atkins,Jan Christensen Pdf

For several months in 1943, seven young airmen, all volunteers, were moulded into an RAF crew tasked with undertaking perilous operations over Occupied Europe. Drawn together from England, Argentina, and Canada, the crew, led by their captain, Flight Lieutenant Peter Bartter, were assigned to 138 (Special Duties) Squadron, based at RAF Tempsford. It was there that they flew low, over dangerous territory to deliver agents and equipment to aid the Resistance in Occupied Europe. When the Allies opened new fronts in North Africa and Italy, Bartter’s crew was seconded for some weeks to 624 Squadron flying from Blida in Algeria and Protville in Tunisia. On their return to the UK, they had the additional task of bringing back Winston Churchill’s son, Randolph. The crew’s last operation would be to fly Flemming Muus, as head of SOE in Denmark, to Roskilde in Denmark. However, tragedy struck when their Halifax Mk.II, BB378, was shot down approaching its destination on the night of 10/11 December 1943. Exemplary piloting skills from Peter Bartter brought the aircraft down in a frozen field with no injuries. Muus thankfully escaped. The crew, meanwhile, split into two groups – the officers, and the NCOs. The officers managed to evade capture and reach Sweden. One of the officers, Ernesto Howell, went on to re-join 138 Squadron, but was sadly killed flying over the North Sea in November 1944. The NCOs’ luck gave out, and they were all captured, spending the rest of the war in the notorious Stalag IV-B. From there, one of the NCOs managed to escape just before the camp liberated by the Russians. In this book, the crew are traced from their recruitment, to training, deployment and, for the survivors, their post-war lives. The next generation, René, son of agent Ernest Gimpel, and Nigel Atkins, son of Brian Atkins, the co-pilot, have become firm friends. Nigel Atkins traveled across Europe on a journey of discovery as he has met and interviewed many people while visiting multiple locations the crew only visited from above. From daring flights over occupied Europe to meetings over seventy years later, the excavation of the crash site and new friendships formed, this book has it all.

The Secrets of Station X by Michael Smith Pdf

The astonishing story of how the British codebreakers of Bletchley Park cracked the Nazi Enigma cyphers, cutting an estimated two years off the Second World War, never ceases to amaze. No one is better placed to tell that story than Michael Smith, whose number one bestseller Station X was one of the earliest accounts. Using recently released secret files, along with personal interviews with many of the codebreakers themselves, Smith now provides the definitive account of everything that happened at Bletchley Park during the war, from breaking the German, Italian and Japanese codes to creating the world's first electronic computer. The familiar picture of Bletchley Park is of eccentric elderly professors breaking German codes, but in fact the vast majority of people who worked at Bletchley Park were young women. For them and for the young graduates plucked from Britain's best universities who did the bulk of the day-to-day codebreaking, this was truly the time of their lives. The Secrets of Station X tells their story in full, providing an enthralling account of one of the most remarkable British success stories of all time.

Bletchley Park and the Belgian Pigeon Service by Bernard O'Connor Pdf

During the Second World War, the British Royal Air Force's Special Duties Squadrons parachuted thousands of pigeons into Belgium. Bletchley Park, the nerve centre of the British Intelligence Service, had its own pigeon loft from where birds were sent on intelligence gathering missions. A secret organisation, MI14(d), was created to organise a pigeon service to occupied Europe. Those who found the pigeons were expected to supply military, economic and political intelligence for the Allies. This book includes the messages sent back from Belgium. In particular, it investigates the roles played by Josef Raskin and Jean Ceysens, the British Intelligence Services, the RAF and the brave individuals who, despite the possibility of imprisonment, sent messages to Britain in the hope it would help liberate their country.

Hoover's Secret War against Axis Spies by Raymond J. Batvinis Pdf

The world was at war, America precariously poised on the sidelines. But already a second secret war was well underway with the United States very much in the thick of it. While he fought on the home front to consolidate the FBI's intelligence gathering power, J. Edgar Hoover was conducting an all-out campaign to make his agency America's first foreign espionage service--a campaign that would lead to an uneasy alliance with British intelligence in a brilliantly successful operation to undermine Germany throughout the Second World War. While pieces of the story have been told before, only now, in this work by FBI historian and former agent Raymond Batvinis, does this crucial chapter in the history of World War II, and of the FBI, received its full due. Taking up the tale begun in his acclaimed Origins of FBI Counterintelligence, Batvinis mines a wealth of heretofore untapped resources to expose Hoover's remarkable connivances and accomplishments in concert--and occasionally contention--with the Allies in outsmarting German intelligence. Hoover's Secret War opens up a world of spy rings, secret and double agents, surveillance, codes and ciphers, wire taps, microdots, mail drops, invisible ink, radio transmissions, and deception and disinformation as it tracks the warring nations spreading their intelligence tentacles throughout Europe and North and South America. As it documents the rocky evolution of the FBI's relationship with Britain's vaunted M15 and M16, the book brings to light the feud between Hoover and William Stephenson, director of the British Secret Intelligence Service's U. S. operation, BSC. Batvinis reveals how the agency gained access to ULTRA intelligence, thanks to the British decryption of the ENIGMA code, along with the strenuous efforts to keep the Germans in the dark about it. He uncovers eye-opening details of the FBI's participation in the famed "Double-Cross System, which effectively "turned" German agents against the Fatherland, among them a flamboyant, larger-larger-than-life playboy, a world famous French flyer, and a lecherous Dutchman. Batvinis tells for the first time how the Bureau manipulated these agents, and how it transmitted deceptive information critical to the Normandy landings, the Allied invasion of the Marshall Islands, and the atomic bomb program, among other matters. Rich with secrets and surprises worthy of the finest spy fiction, this true story of espionage and counterintelligence gives us our first clear look at the secret second world war, and a significant moment in history--for the FBI, for America, and for the world.

Secrets and Lies in Vietnam by Panagiotis Dimitrakis Pdf

The Vietnam War lasted twenty years, and was the USA's greatest military failure. An attempt to stem the spread of Soviet and Chinese influence, the conflict in practice created a chaotic state torn apart by espionage, terrorism and guerilla warfare. American troops quickly became embroiled in jungle warfare and knowledge of the other side's troop movements, communication lines, fighting techniques and strategy became crucial. Panagiotis Dimitrakis uncovers this battle for intelligence and tells the story of the Vietnam War through the newly available British, American and French sources - including declassified material. In doing so he dissects the limitations of the CIA, the NSA, the MI6 and the French intelligence- the SDECE- in gathering actionable intelligence. Dimitrakis also shows how the Vietminh under Ho Chi Minh established their own secret services; how their high grade moles infiltrated the US and French military echelons and the government of South Vietnam, and how Hanoi's intelligence apparatus eventually suffered seriously from 'spies amongst us' paranoia. In doing so he enhances our understanding of the war that came to define its era.

GCHQ by Nigel West Pdf

The go-to intelligence expert and author of MI6 has “provided the clearest review of GCHQ and its predecessors in a publicly available book” (Firetrench). Signal intelligence is the most secret, and most misunderstood, weapon in the modern espionage arsenal. As a reliable source of information, it is unequalled, which is why Government Communications Headquarters, almost universally known as GCHQ, is several times larger than the two smaller, but more familiar, organizations, MI5 and MI6. Because of its extreme sensitivity, and the ease with which its methods can be compromised, GCHQ’s activities remain cloaked in secrecy. In GCHQ: The Secret Wireless War 1900-1986, the renowned expert Nigel West traces GCHQ’s origins back to the early days of wireless and gives a detailed account of its development since that time. From the moment that Marconi succeeded in transmitting a radio signal across the Channel, Britain has been engaged in a secret wireless war, first against the Kaiser, then Hitler and the Soviet Union. Following painstaking research, Nigel West is able to describe all GCHQ’s disciplines, including direction-finding, interception and traffic analysis, and code-breaking. Also explained is the work of several lesser known units such as the wartime Special Wireless Groups and the top-secret Radio Security Service. Laced with some truly remarkable anecdotes, this edition of this important book will intrigue historians, intelligence professionals and general readers alike. “Nigel West is an acknowledged expert in this field of literature and his latest book is fascinating and intriguing.” —Books Monthly “Rich in the kind of detail from which all students of radio and military history can learn.” —The Spectrum Monitor

Bletchley Park and the Pigeon Spies by Bernard O'Connor Pdf

Over 15,000 pigeons were dropped into occupied Europe during WW2. Some were used by secret agents to send messages back to headquarters. Others were dropped by parachute into France, Belgium, Holland and Denmark in the hope that people would complete the attached questionnaire and provided military, political, economic or other intelligence of value for the Allies. Photographic negatives could be sent. Bletchley Park had its own loft for its pigeon spies. This book investigates the work of MI14, known as the Colomba Service, and for the first time sheds light on conditions in Occupied Europe described by extremely brave men and women who risked execution if found in possession of a pigeon. MI14 staff, decoded or translated messages and forwarded copies to SOE, SIS, MI19, RAF, RN, Ministry of Economic Warfare, BBC, Churchill, de Gaulle and President Benes of Czechoslovakia.
