The Battle of Agincourt was fought on 25 October 1415 and was a major win for England against France in the Hundred Years' War. It led to several later English victories. Henry V of England led the English army and Constable of France Charles d'Albret led a larger French army. King Charles of France didn't engage because he was mentally unwell. Henry V was involved in hand to hand combat and was struck by an axe but his helmet saved him.
