Description
Discover the captivating history of British codebreaking in 'Images of The National Archives: Codebreakers' by Stephen Twigge. This brand new paperback, comprising 136 pages, dives deep into the secret world of ciphers and intelligence, stretching from the reign of Elizabeth I through to the Cold War era. Unravel the enigma behind the Royal Mail's Secret Office and the influential Room 40 of the Admiralty, which laid the groundwork for the Government's Code and Cypher School. The primary focus is the pivotal operations during World War II, particularly at Bletchley Park, where a remarkable team of codebreakers thrived to decrypt the formidable German Enigma codes. Their groundbreaking work led to the production of Ultra intelligence, which significantly impacted key military events, notably during the Battle of the Atlantic and the D-Day landings in June 1944. This enlightening book also details the efforts made in the Far East, particularly in deciphering the Japanese military cipher known as Purple. Further, the narrative honors the legacy of Alan Turing, a pivotal figure in codebreaking, and offers insights into the subsequent developments by GCHQ in the early Cold War. Perfect for history enthusiasts, this book is an essential addition to your collection on espionage and wartime strategies. Order now and secure your copy for fast delivery across New Zealand!

The book reveals the story of British Codebreakers from the reign of Elizabeth I to the Cold War. It explores the use of ciphers during the Napoleonic wars, the role of the Royal Mail's Secret Office and the activities the Admiralty's Room 40' leading to the creation of the Government's Code and Cypher School. The main theme of the book are the events of the Second World War and the battle to break the German enigma codes. The centre of Britain's codebreaking operation was located at Bletchley Park in rural Buckinghamshire and it was from here that a hastily assembled army of codebreakers battled to decipher Nazi German's secret wartime communications. The deciphered high-level signals intelligence was known as Ultra and had a major influence on the outcome of the war, most notably contributing to crucial successes in the battle for the Atlantic and the D-Day landings in June 1944. The book also reveals the work undertaken in the Far-East and the allied efforts to break the Japanese military cipher code named Purple. The book ends with a re-assessment of the work undertaken by the British code breaker and mathematician Alan Turing and a brief overview of the codebreaking operations undertaken by GCHQ during the formative period of the Cold War. AUTHOR: Stephen is a senior historian at The National Archives. He obtained his PhD from the Centre of Science, Technology and Medicine at the University of Manchester and was a Post-Doctoral Research Fellow at the Department of International Politic
