Joan launched an attack on Beaugency. Joan of Arc and Duke John II of Alençon controlled a force that included captains Jean d'Orléans, Gilles de Rais, Jean Poton de Xaintrailles, and La Hire. John Talbot led the English defense. Breaking with siege warfare custom, the French army followed the 15 June capture of the bridge at Meung-sur-Loire not with an attack on that town or its castle but with an assault on neighboring Beaugency the next day.

Unlike Meung-sur-Loire, the main stronghold at Beaugency was inside the city walls. During the first day of fighting the English abandoned the town and retreated into the castle. The French bombarded the castle with artillery fire. That evening de Richemont and his force arrived.

Hearing news of an English relief force approaching from Paris under Sir John Fastolf, d'Alençon negotiated the English surrender and granted them safe conduct out of Beaugency.
