What were the average casualties (Killed vs. Wounded) armies would face in the Medieval Period after a battle relative to the size of the army?

by Aegon1776

There is little numerical record-keeping of casualties for combat in the middle ages, but I was wondering if there are any ideas or sources that point to the level of casualties an army would suffer after a battle.

More can always be said on the matter, and any further insight is quite welcome. For the meantime, as Medieval-era casualty count pops up every so often, I commend to your attention several previous answers:

  • This question about Medieval combat has an excellent thread on the matter, starting from u/Hergrim's answer, which should be top.
  • There's also this post with answers from u/Iphikrates and u/Iguana_on_a_stick, which is more focused on Greek and Roman warfare, though the concerns are comparable.
