Later in 1939, Fromond went to Belgium to work for the Czech Communist leader
Eugen Fried. She was then sent to Denmark to liaise with Giulio Ceretti, and was arrested in May 1940 but was freed after a few weeks as a result of Soviet diplomatic intervention, and returned to the Soviet Union. She arrived near Montpellier, where she was to set up a radio station, with the assistance of her own mother and another Resistance worker,
Joséphine Turin, codenamed "Fifi". On 30 July 1943 all three women were arrested by the
Sonderkommando Rote Kapelle and sent to
Fresnes Prison, where Francine's mother, Germaine, died as a result of ill-treatment. Fromond and Turin were tortured by the Gestapo at Lyon but revealed nothing. They were sent to Paris and then to Lyon for trial, and were executed on the same day in 1944, a short time before the country was liberated. ==Legacy==
