5.0. Surprise round. Longbow retreat. Wash worse repeat. Rough terrain.
England. Foods terrible moral collapses and they flee after getting peppered by arrows. Rangers vs slow fighter types.
NPCs archers trained in stealth vs low dexterity slow English troops. They have bad food but very good jesters.
English learn the hard way. Pull out 5.5 rules. Surprise round less effective and grind them down. Get clowned on by the French next 500 years then pay off everyone else to do the dying them spend 80 years mocking the French with those excellent jesters. Foods still terrible though.
