Groups Francs changed their operations style. They were ordered to attack trains containing German soldiers or going to Germany, to sabotage railway lines, to destroy arms factories and dumps and to assassinate Gestapo agents. The GF were supplied and armed by Britain through parachute dumps which provided them with Sten guns, pistols, ammunition, explosives, grenades and other equipment. The GF also organised escapes for captured resistance fighters such as that of Paul Reynaud (planned and prepared but never executed) and the successful escape of Berty Albrecht who was being held at the Lyon-Bron psychiatric hospital. In January 1943, Jacques Renouvin, was arrested by the Gestapo getting off a train. He was held in Fresnes prison. A commando raid was mounted to free him but all its members were arrested. Renouvin was deported to Mauthausen concentration camp where he died. He was replaced as head of the GF by a member of Libération. The Maquis In 1943 the steering committee of Combat learned that refugees from the Service du travail obligatoire forced labour had fled to Haute-Savoie and the Maquis had been created in the mountainous massifs. The service Maquis was established in Combat's Military affairs branch with the aim of helping all those who had "taken the maquis" to survive and to fight, and of providing them lives and armaments, and of integrating them into Combat's network. While the objective for Combat was to develop, oversee and organise these armed groups, there were some divisions relating to this at the heart of the MUR; some, like Charles Delestraint, saw the Maquis as actual pockets of resistance within French territory, whereas others like Frenay saw them as armed bands operating by ambush and disappearing once their mission was accomplished.
