The Vichy forces did fight the allied landings of Torch for three days, although there wasn't much they could do to stop it. After they surrendered they formally joined the Allied side and laid the foundation for the revival of the French Army. I would be much more interested in using them this way than fighting for Vichy against the Allies. Perhaps a more interesting set would be for the French Army from 1943-1945, with a combination of equipment and weapons of French, British, American and African origin. Morrocan Goumiers would also be welcome. Battlefield miniatures makes them, but no one has done them in plastic so far.
I agree RCD. Many people may be unaware of these actions, and in particular the hard fought campaign in Syria. Coming from Australia I am more aware of this due to Australian involvement.It provides an interesting campaign with Vichy Regular, Colonial, African and Levantine troops well supported by Aircraft, Tanks and Armoured cars vs Australian, Indian, British and Free French, who lacked material support.
