Hundred Years' War (1415–53)
By 1449, the French had retaken Rouen. In 1450 the Count of Clermont and Arthur de Richemont, Earl of Richmond, of the Montfort family (the future Arthur III, Duke of Brittany) caught an English army attempting to relieve Caen at the Battle of Formigny and defeated it. The English army was attacked from the flank and rear by Richemont's force just as they were on the verge of beating Clermont's army. The French proceeded to capture Caen on July 6 and Bordeaux and Bayonne in 1451. The attempt by Talbot to retake Guyenne, though initially welcomed by the locals, was crushed by Jean Bureau and his cannons at the Battle of Castillon in 1453 where Talbot had led a small Anglo-Gascon force in a frontal attack on an entrenched camp. This is considered the last battle of the Hundred Years' War.
Anglo-Scottish Wars
France also played a key role throughout the period of the Anglo-Scottish Wars. Scots and English soldiers on French soil during the Hundred Years War (1337–1453) generally fought on opposing sides, with the Scots standing for the French against the English under the Auld Alliance. France in later periods, in turn, often intervened on Scottish soil for the Scots. This French involvement had increasingly complex political consequences for all sides by the later 16th century.
