Overview
Ronald Koorm has spent years researching and presenting the story of Britain’s codebreaking outstations, uncovering what many consider the final piece of the Bletchley Park puzzle.
Filled with extraordinary stories, Backing Bletchley explores the people, places, and innovations that supported Britain’s wartime codebreaking efforts. Who built the world’s first electronic digital computer? Tommy Flowers—but not at Bletchley Park. His groundbreaking work took place at Dollis Hill.
Drawing on the first detailed study of the Bombe registers held at the National Archives, Koorm offers fresh insights into the enduringly fascinating story of Bletchley Park and its network of support outstations. He examines the origins of the Enigma machine, the vital role of Eastcote as the largest codebreaking outstation during the Second World War, and the development of improvements to Alan Turing’s Bombe machine.
The book also highlights the crucial contribution of the Women’s Royal Naval Service (WRNS), whose members operated the machines under immense pressure. Through their stories, Koorm reveals how women from diverse backgrounds demonstrated remarkable teamwork and resilience at the codebreaking sites.
After the war, Eastcote became home to GCHQ before the organization moved to Cheltenham. The site later played a variety of roles, including involvement in Cold War counterintelligence operations. Koorm also explores the connections between Alan Turing and other pioneering thinkers in the quest for artificial intelligence, showing how the talents and innovations of wartime codebreakers helped shape the modern world.
Featuring previously unpublished diagrams, charts, and illustrations, Backing Bletchley sheds new light on the remarkable events and individuals behind one of the most important intelligence operations in history.
