The incredible and inspiring story of Elzbieta Zawacka, the World War II female resistance fighter known as Agent Zo.



During World War II, Elzbieta Zawacka—the WWII female resistance fighter known as Agent Zo—was the only woman to reach London as an emissary of the Polish Home Army command. In Britain, she became the only woman to join the Polish elite Special Forces, known as the 'Silent Unseen.' She was secretly trained in the British countryside, and then she was the only female member of these forces to be parachuted back behind enemy lines to Nazi-occupied Poland. There, while being hunted by the Gestapo (who arrested her entire family), she took a leading role in the Warsaw Uprising and the liberation of Poland.



After the war, she was discharged as one of the most highly decorated women in Polish history. Yet the Soviet-backed post-war Communist regime not only imprisoned (and tortured) her, but also ensured that her remarkable story remained hidden for over forty years. Now, through new archival research and exclusive interviews with people who knew and fought alongside Agent Zo, Clare Mulley brings this forgotten heroine back to brilliant life—while transforming how we value the history of women resistance fighters during World War II.
