The Codebreakers of the First World War
The Story of Room 40 & MI1(b) during the Great War, 1914-1918
The story of Bletchley Park during the Second World War is now well known. However, Bletchley Park did not arise out of a vacuum. This book recounts how British codebreakers learnt their trade during the First World War, with decisive effect in the war on land (especially at the First Battle of the Marne in 1914 and during the final months of the war on the Western front in 1918, and also in the Middle East), in the war at sea (including the Battle of Dogger Bank and the Battle of Jutland, and also in the war against German submarines), and the war in the air (in the ‘First Battle of Britain’). British codebreakers also played a critical role in bringing the USA into the war by intercpeting and decrypting the so-called Zimmermann Telegram’ in 1917. Based on archive documents and personal accounts this book is a vibrant record of the role played by British codebreakers between 1914 and 1918.
