A third appealed for clemency from the French authorities, who have a policy of arresting returning jihadis.
"I've done hardly anything but hand out clothes and food," he said. "I've also cleaned weapons and moved the bodies of killed fighters. Winter is beginning. It's starting to get tough."
Over 1100 young French people - many of them converts to Islam of French rather than Arab origin - are believed to have thrown in their lot with Isis or other jihadist groups.
Over 260 are believed to be in Syria or Iraq. More than 100 have already returned. Of these, 76 have been arrested. A group of French lawyers is working with relatives to try to ease the passage home of scores of other Isis recruits, according to Le Figaro.
They have collected text messages and emails which suggest that many of the volunteers feel that they have been "cheated" into making the hazardous journey to the Middle East.
Some messages reveal a fear of death or injury.
"They want to send me to the front but I don't know how to fight," one young man said.
