Germaine Tambour successively belonged to several Resistance networks (code name “Annette”): Her apartment at 38 avenue de Suffren,[3] Paris XVe, where she lived with her sister Madeleine, served as a mailbox and safe house for a large number of Special Operations Executive agents in late 1942 and early 1943, starting with Andrée Borrel and Francis Suttill upon their arrival in France.
[4] Prefiguring the general collapse of the Prosper network at the beginning of the summer, she was arrested, along with her sister Madeleine, on April 22, 1944,[5] then interned in Fresnes.
Worried, Francis Suttill and members of his management team (Armel Guerne, Jean Worms, Jacques Weil) set up an operation to try to get them to escape by bribing a French policeman.
Mrs. Flamencourt heard the testimony of Germaine Tambour in prison: "She told me how painfully surprised she had been during the interrogation to be put in the presence of Gilbert Norman, who seemed to enjoy a diet of favor, serving tea to the Germans and showing them, on a map spread out on the table, the airdrop sites and the arms depots.
A plaque affixed to the facade of the building at 38, avenue de Suffren pays homage to her, as well as to her sister Madeleine and to Marie-Louise Monnet.
