On April 15, 1450, French forces under the Comte de Clermont engaged Sir Thomas Kyriell's English army near Formigny in Normandy. English longbowmen initially repelled French advances, but Jean Bureau's culverins — among the first recorded uses of field artillery in European battle — disrupted their lines. When Constable Arthur de Richemont's Breton cavalry struck the English flank, the position collapsed. English losses exceeded 2,500 killed and 900 captured. The victory enabled France to retake Caen, Bayeux, and the remaining English-held towns, ending English control of Normandy within months.
