So i have been wandering about this. So for example, there is a battle in the middle ages. Two soldiers, both have close combat weapons, approach eachother. How long would the fight between the two last? I hope someone has a clear answer how this kind of fighting would go down.
There's no way anyone could answer that in a way that makes sense. Battles were not the sum of a series of individual duels. They were large, complex, and chaotic affairs that were confusing for all participants. Men were ganging up on enemies cut off from support, flanking each other, getting in each other's way, etc. If any one conclusion could be made, it's that any fight between two individuals would be fairly quickly, if only because their fellow soldiers would be intervening and either pushing the two apart (as one group withdrew) or concluding the fight in favor of one side or another.
We have no data on this for later periods of Greek history, but in the Iliad, the overwhelming majority of combats between individual warriors are decided with a single blow. Javelins and spears are used to put opponents out of action instantly. Only very rarely (for example in the duel between Achilles and Hektor) do both heroes throw their javelins in vain, forcing them to continue fighting with their swords.
