'Bletchley Park's Secret Room' is Major Neil Webster's posthumous account of the secret code-breaking process in Bletchley Park's Fusion Room during the Second World War.

This is the last untold story of Bletchley Park. Using declassified information, Paul Gannon gives us a gripping account of the invention of the world's first true computer, Colossus. Uncover the secrets of Bletchley Park's code-breaking computers. In 1940, almost a year after the outbreak of the Second World war, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation Bletchley Park codebreakers 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 codebreakers didn't realize was that they had to fashion 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. 'Gannon's book contains a mass of utterly fascinating and largely unknown material about an immensely important wartime project, and is very welcome indeed.' - Brian Rendell, TES

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

The story of how one man, working in obscurity and total secrecy, influenced the course of world history over 30 years of war and peace

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.

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

The secret military facilities hidden across Great Britain are revealed and investigated in this fascinating WWII history. During the Second World War, thousands of facilities across Britain were requisitioned to support the war efforts. Beyond that, countless others were built from scratch. Often the purpose of these locations was a closely guarded secret, even from those living close by. In Secret Wartime Britain, Colin Philpott has compiled a fascinating collection of sites that still exist in some form today. They include underground factories, storage sites and headquarters; spy and communication centers; interrogation and POW camps; dummy sites; research facilities such as the sinister Porton Down; treasure stores in stately homes and even royal retreats in the event of invasion, such as Madresfield Court. Where were these sites and why were they needed? How successfully were they kept secret? What has happened to them since? Were they returned to their owners? Answers to these and other questions make Secret Wartime Britain a riveting and revealing read.

To defeat your enemies you must know them well. In wartime, however, enemy codemakers make that task much more difficult. If you cannot break their codes and read their messages, you may discover too late the enemy's intentions. That's why codebreakers were considered such a crucial weapon during World War II. In Secret Messages, David Alvarez provides the first comprehensive analysis of the impact of decoded radio messages (signals intelligence) upon American foreign policy and strategy from 1930 to 1945. He presents the most complete account to date of the U.S. Army's top-secret Signal Intelligence Service (SIS): its creation, its struggles, its rapid wartime growth, and its contributions to the war effort. Alvarez reveals the inner workings of the SIS (precursor of today's NSA) and the codebreaking process and explains how SIS intercepted, deciphered, and analyzed encoded messages. From its headquarters at Arlington Hall outside Washington, D.C., SIS grew from a staff of four novice codebreakers to more than 10,000 people stationed around the globe, secretly monitoring the communications of not only the Axis powers but dozens of other governments as well and producing a flood of intelligence. Some of the SIS programs were so clandestine that even the White House—unaware of the agency's existence until 1937—was kept uninformed of them, such as the 1943 creation of a super-secret program to break Soviet codes and ciphers. In addition, Alvarez brings to light such previously classified operations as the interception of Vatican communications and a comprehensive program to decrypt the communications of our wartime allies. He also dispels many of the myths about the SIS's influence on American foreign policy, showing that the impact of special intelligence in the diplomatic sphere was limited by the indifference of the White House, constraints within the program itself, and rivalries with other agencies (like the FBI). Drawing upon military and intelligence archives, interviews with retired and active cryptanalysts, and over a million pages of cryptologic documents declassified in 1996, Alvarez illuminates this dark corner of intelligence history and expands our understanding of its role in and contributions to the American effort in World War II.

For a long time, the Australian Signals intelligence (or Sigint) story has been kept secret. Until now… Why does Australia have a national signals intelligence agency? What does it do and why is it controversial? And how significant are its ties with key partners, the United States, the United Kingdom, Canada and New Zealand, to this arrangement? Revealing Secrets is a compelling account of Australian Signals intelligence, its efforts at revealing the secrets of other nations, and keeping ours safe. It brings to light those clever Australians whose efforts were for so long entirely unknown or overlooked. Blaxland and Birgin traverse the royal commissions and reviews that shaped Australia’s intelligence community in the 20th century and consider the advent and the impact of cyber. In unearthing this integral, if hidden and little understood, part of Australian statecraft, this book increases our understanding of the past, present and what lies ahead. ‘George Orwell famously wrote during World War Two, “we sleep safe in our beds because rough men stand ready in the night to visit violence on those who would do us harm”. Reading this superb history by John Blaxland and Clare Birgin on Australia’s involvement with Sigint and cyber we can contemplate a new formula. We sleep safer because 24/7 intelligent, technologically competent patriotic men and women who work for our agencies, develop and work our electronic defence and offence capacities at worldclass standard. This in a world now in which we are constantly under attack. The work so secret it is proving impossible to produce an official history. This is the closest we can get and it is very good. If you are seriously interested in our defence and survival, or you would just like a good read, this belongs on your bookshelf.’ — Kim Beazley, former Defence Minister ‘A meticulous compilation of the largely unsung past achievements of our most consistently productive intelligence source. And a thoughtful analysis of how to approach the extraordinary challenges posed by the new cyber universe. Blaxland and Birgin make an important contribution to our understanding of issues needing much more open debate than our own and allied governments have traditionally allowed or encouraged.’ — Gareth Evans, Former Australian Foreign Minister ‘Australia has been part of sigint since the practice began, which has shaped its history in ways that Australians know little about. Their government likes to keep things that way. Revealing Secrets overcomes efforts to keep Australians ignorant about their sigint history, by discussing everything that can be said about it without access to secret records. Anyone interested in the past and future of Australia has much to learn from this book.’ — John Ferris, author of Behind the Enigma, The Authorised History of GCHQ, Britain’s Secret Cyber Intelligence Agency ‘The most comprehensive and best-informed account we have had of the history of signals intelligence in Australia. Essential reading for anyone seeking to understand not just our country’s past, but Australia’s strategic future as well.’ — Allan Gyngell, author of Fear of Abandonment: Australia in the World Since 1942 ‘Revealing Secrets tell the remarkable but little-known story of how a small, back-room military office grew into a major Australian government agency. Deeply researched, authoritative and accessible, it is a valuable and timely contribution to understanding issues that have never been more important to national security.’ — Emeritus Professor David Horner, author of The Spy Catchers

In this title, Ian Hawkins draws together numerous stories from those men who served on the B- and C-class destroyers, weaving them together using excerpts from books, news articles, speeches, and his own authoritative notes.
