How did one woman become one of the most extraordinary figures in the Polish Resistance?

In this powerful episode of History Book Buffs, Antonia Senior speaks to award-winning historian and biographer Claire Mulley about her brilliant book Agent Zo — the story of Elżbieta Zawacka, known as Agent Zo, a resistance courier, Warsaw Uprising fighter, and one of the most remarkable women of the Second World War.

But this conversation goes far beyond one life. Through Zo’s story, we explore the wider tragedy of Poland in World War Two: the double invasion by Nazi Germany and the Soviet Union, the heroism of the Polish Home Army, the devastation of the Warsaw Uprising, and the crushing betrayal that followed when Stalin arrested 16 leaders of the Polish underground in March 1945.

Claire Mulley explains how Zo became the only woman to parachute from Britain into occupied Poland, how she fought for women to be recognised as soldiers, and how she survived war only to be persecuted by the communist regime that followed. This is a story of courage, resistance, betrayal, and the long fight for Polish freedom.
