The Battle of Patay, fought on 18 June 1429 during the Hundred Years' War, was the culmination of the Loire Campaign between the French and English in north-central France. In this engagement, the horsemen of the French vanguard inflicted heavy casualties on an English army; most of them sustained by the longbowmen as the English cavalry fled. In addition, all but one of the senior English commanders were captured. A victory often credited to Joan of Arc, she was in fact not present for the battle as she had remained with the main body of the French army. The vanguard at Patay was led by La Hire and Jean Poton de Xaintrailles.

The Loire Campaign was a campaign launched by Joan of Arc during the Hundred Years' War. The Loire was cleared of all English and Burgundian troops.
