I was reading Count of Monte Cristo and there some of the characters theorize that Napoleon, coming from Elba, could be landing either in Tuscany or in Naples, rather than France. What would be the consequences of such a move?
There's no logical reason why he would do this. The entire reason for his escape from Elba was to retake his throne. It doesn't make any sense that he'd land in Italy.
It was closer. He could use Italian armies to add them back to the French ones later on, as France's were depleted. His brother-in-law, Murat, ruled in Naples too and allied with him in OTL Hundred days.
