During WWII, when the Nazis broke their armistice agreement and occupied Vichy France and advanced to the naval base in Toulon to seize the warships there. The French had 3 battleships, 1 seaplane carrier, 4 heavy cruisers, 3 light cruisers, 16 destroyers, 8 sloops, 13 torpedo boats, and 15 submarines. On November 27, 1942, the French scuttled their fleet to prevent the Germans from getting their hands on them.
My question is this: How would the balance of naval power in the Mediterranean have been affected in the Germans had been allowed to seize these ships. It would bolster an already powerful Kriegsmarine. The Italian Navy, a powerful force in the Med, was still in the game. In your minds, how would the Battle of the Mediterranean and the North Africa Campaign be affected?
