During her second mission, Szabo was caught by the Germans. She was interrogated, and sent to Ravensbrück concentration camp in Germany, where she was treated harshly. Like most other prisoners, she had to perfom hard work in freezing cold conditions with few clothes. She was shot near the end of the war. After her death, she was awarded the George Cross, the Croix de Guerre and the Medaille de la Resistance.
