Don’t know exactly.. but those who did were the cream of the French crop. de Gaulle was leading from the back I understand..until the Americans let him take Paris and his 1st Armoured Division parade down the Paris main drag with him marching at their head like a 7ft tosser.
If ever a man was a drag on the Allied war effort it was de Gaulle!! As was proved later he had no love for the USA or the UK.
French troops fought bravely on D-Day.
French Commandos stormed ashore at Ouistreham and battered the Germans there(immortalised in The Longest Day). French Naval ships also supported the landings.
