What if France had not surrendered and continued the fight from North Africa using the French Navy and the 120k troops in Africa plus what could be salvaged from France?

France would have been unable to mount any type of offense from North Africa. Logistics would have ruled it out. France's European army was unable to defend the nation even though on paper it was much more powerful than Germany's. France tried to fight WW1 over again and failed, poor coordination, bad leadership, and quick decisive strikes by the Germans ended the war in Europe quickly. In North Africa, France may have been able to inflict a Sunday punch with what was available, but wouldn't have been able to sustain it without supplies. The French Navy was old but numerous and it is tragic it met its fate by the hand of England rather than join with the Royal Navy.
