Apparently in December 1941 Vichy France approached Alan Brooke about the idea of Allied troops landing in Bordeaux and La Rochelle and then arming the Vichy Army which would aid in the Allied liberation of France. But this plan never came to anything, because the Vichy had to go around Churchill to even bring the idea to British. Alan Brooke and other higher ups in the British military eventually approved the plan in July 1942, but the plan died after the Free Zone was occupied as a result of Operation Torch.
What if Alan Brooke had approved the plan earlier and going around Churchill had informed the Americans who disliked de Gaulle?
Would the Americans accept it and then could France be liberated in say 1943 like Marshal wanted?
What effect would this have on Free France, which at the time controlled various French colonies, might there be a civil war or what after Germany is defeated?
