Napolionic Charisma

Napoleon was almost as famous for being charismatic as he is for his short stature.

Napoleon wasn't short.
Was he charismatic?

How many people followed him for him, instead of because of the alternative option or the promises he made? How much of a factor was his charisma, actually?

I don't know, but I'd assume that most people followed for his promises and the threats posed by his opposition. After all, charisma has the most pull on the people closest to you, and writing and speeches only go so far. Napoleon could not possibly have known everyone who followed him personally: there were simply too many people. Public speeches could inspire those who hear it, but only so many people could hear any given speech, and each time someone passes on word of his charisma, passion, and whatever else Napoleon demonstrated while speaking, the actual glow of his charisma would be transfered less and less. Out of all the time he spent working with and on France, how much of that time was spent in public, densly-populated areas, and how much was away from most of the people he'd want to sway?
