I have read various tales of two armies meeting on a battlefield, but rather than fight, the two leaders agree to one-on-one combat, and the winner decides the war, thus saving on bloodshed.
Are there any historical examples of that sort of thing? Are there any examples where it was attempted but the armies went to war anyway? It just seems like such a prevalent myth, and most myths have some grounding in history, but I don't know of any.
