In 1942, the Allies were losing, Germany seemed unstoppable, and every able man in England was on the front lines. To “set Europe ablaze,” in the words of Winston Churchill, the Special Operations Executive  (SOE), whose spies were trained in everything from demolition to sharpshooting, was forced to do something unprecedented: recruit women. Thirty-nine answered the call, leaving their lives and families to become saboteurs in France.

I’m talking with Sarah Rose, author of, D-Day Girls about the stories of three of these remarkable women. There’s Andrée Borrel, a scrappy and streetwise Parisian who blew up power lines with the Gestapo hot on her heels; Odette Sansom, an unhappily married suburban mother who saw the SOE as her ticket out of domestic life and into a meaningful adventure; and Lise de Baissac, a fiercely independent member of French colonial high society and the SOE’s unflap­pable “queen.” Together, they destroyed train lines, ambushed Nazis, plotted prison breaks, and gathered crucial intelligence—laying the groundwork for the D-Day invasion that proved to be the turning point in the war.
