Battle of Agincourt (1415), Chronicle of Enguerrand de Monstrelet, circa 1470, illuminator: Master of the Chronicle of England

The Battle of Agincourt resulted in King Henry V of England's under-numbered armies' crushing victory over the French.
The cavalry was arranged behind the infantry entrenched behind the shields of the archers planted upright into the ground. The infantry opened its ranks to allow for the passage of the cavalry charging at a gallop then returned in disorder towards its own infantry in order to prepare a new charge.
As in Crécy, the Battle of Agincourt was marked by the victory of foot soldiers and projectile weapons over horse soldiers. It also marked the end of the supremacy of horse soldiery and the advent of ranged weapons for battle.
