Battle of Formigny

Battle context

The Battle of Formigny, fought on 15 April 1450, was a decisive French victory that effectively ended England's capacity to hold Normandy. By destroying the last significant English field army in the duchy, the battle removed the principal military obstacle to French reconquest. With no comparable force remaining to contest the territory, France was positioned to systematically reduce the English-held strongholds that remained. The engagement thus stands as a turning point in the final phase of the Hundred Years' War, accelerating the collapse of English territorial control in Normandy that had been consolidated over decades of occupation. The French force of approximately 4,200, under Jean de Clermont, Arthur de Richemont, and Pierre de Brézé, faced an English army of roughly 4,000 under Thomas Kyriell. French casualties of around 1,000 indicate the engagement was genuinely contested despite the decisive strategic outcome.
