Yvonne Baseden’s remarkable wartime experience began with her service in the Women’s Auxiliary Air Force (WAAF). While working at the Directorate of Allied Air Cooperation and Foreign Liaison, she met Pearl Witherington, who—unknown to Yvonne—was an agent for the Special Operations Executive (SOE). It was this connection that Yvonne believes led to her being recruited by the SOE. 

Due to the SOE’s covert nature, Yvonne was officially attached to the First Aid Nursing Yeomanry (FANY), a common practice for female agents during World War II. Bilingual in English and French, she was considered a natural fit for operations in occupied France. Her first mission involved parachuting into France as a wireless operator to assist the French Resistance.

However, after successfully completing Operation Cadillac—a major arms drop supporting liberation efforts—her location was compromised. Captured and transferred to Dijon prison, she was interrogated and faced threats of being sent to Gestapo headquarters in Paris. Despite this, Yvonne never revealed her true identity as an English agent, maintaining her cover as a French Resistance fighter. 

Instead of being sent to Paris, Yvonne was transferred to Ravensbrück, the largest female-only concentration camp. She recalls the pressure of concealing her SOE status, aware that other female English agents in the camp had been executed. Fortunately, Yvonne was rescued by the Swedish Red Cross in the final days of the war and taken to Malmö, Sweden for recovery before safely returning home.
