Agincourt - where the French cavalry got bogged down literally.
Probably apocryphal, but some legend has it that raising the middle finger as an act of defiance had its roots at Agincourt. As the story goes, the French so hated the English archers that if captured, they would lol of the archer’s middle fingers rendering them ineffective. In defiance the archers would flip the bird to the French arrayed before them.
