The PCF (Communist Party) encouraged desertion and sabotage against the French war effort before the Battle of France. For a period of time, their newspaper was allowed to print under Nazi occupation.
They got into the resistance game only because of Barbarossa and dominated it. They truly were more beholden to Stalin and his Comintern/Cominform.
The French resistance was communist dominated. I tried to read a book about it once and couldn't make heads or tails of the thing. Finally I figured out that it was the same tripe as other commie loving books. All words that didn't mean anything.
