Andree was contributing to the war effort even before becoming a spy. This French national and her friend were responsible for an underground railway into Spain, which they used to evacuate downed Allied airmen from occupied France. When the network was betrayed in 1940, she fled to Portugal and eventually joined SOE in 1942.
She was one of the first female agents to parachute into France along with Lise de Baissac on September 24, 1942.
After joining the resistance in Paris, she became second in command of the local network by March 1943.
Responsible for attacking a power station and other infrastructure, she and three key members were arrested.
After proving too tough to crack through interrogation, she was taken to a concentration camp where she was given a lethal injection.
Andree regained consciousness after the injection. Fighting the doctors for her life, she was eventually overpowered and cremated while alive.
