Uncover the secret history of WWI with the codebreakers of Room 40 and MI1(b).
Bletchley Park's WWII codebreaking is famous, but its WWI counterparts remain in the shadows. From the Marne to the Zimmermann Telegram, a cast of eccentric characters secretly guided the Great War from smoke-filled rooms.
Bestselling author Paul Gannon uses intercepted German messages to reveal British codebreaking operations. Discover newly uncovered archival documents that challenge misleading stories about Room 40 & MI1(b), revealing a sophisticated machine in operation. Perfect for readers interested in military history, intelligence, and cryptography.
