French Mediterranean ports after a counterfactual Fashoda defeat

Would France lose Mediterranean access after defeat in a wider war triggered by Fashoda?

Probably not all its coastline, but the suggested loss of Marseille, Toulon and Corsica would reduce French naval access and strengthen Italy.

A French defeat is not expected to remove every stretch of Mediterranean coastline, because an Italian advance to the Spanish border is considered unlikely. The imagined settlement could still transfer Marseille, Toulon and Corsica to Italy. Losing those ports would sharply reduce France's naval access even if it retained a smaller coastline. Acquiring them would also strengthen Italian industry and naval capacity. Britain might then support a stronger Italy as a counterweight to Germany if France could no longer fill that role.
