In 1942, the Allies were losing, Germany seemed unstoppable, and every able man in England was fighting. Believing that Britain was locked in an existential battle, Winston Churchill had already created a secret agency, the Special Operations Executive (SOE), whose spies were trained in everything from demolition to sharpshooting. Their job, he declared, was to ‘set Europe ablaze’. But with most men on the front lines, the SOE was forced to do something unprecedented: recruit women. 39 answered the call, leaving their lives and families to become saboteurs in France. In ‘D-Day Girls’, Sarah Rose draws on recently declassified files, diaries, and oral histories to tell the thrilling story of three of these remarkable women.
