Main thing to remember with this story is that its Ceaser's own account of what happened, written specifically to mythologize himself. It's guaranteed that he's lying, it's guerenteed that it didnt happen like this. The only real question is whether he's lying because it was a much harder fight and he wants to seem stronger, or whether it was a much easier fight and he wants his opponent to seem stronger.
Edit: apologies for the hasty, under-researched comment. I went into a momentary anti-roman fugue state.
Ya fair enough. I get defensive of Vercingetorix because so many people meme him into a punching bag.
