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.
Loire
In the 9th century, the Vikings began invading the west coast of France, using longships to navigate the Loire. In 853 they attacked and destroyed Tours and its famous abbey, later destroying Angers in raids of 854 and 872. In 877 Charles the Bald died, marking an end to the Carolingian dynasty. After considerable conflict in the region, in 898 Foulques le Roux of Anjou gained power.
During the Hundred Years' War from 1337 to 1453, the Loire marked the border between the French and the English, who occupied territory to the north. One-third of the inhabitants died in the epidemic of the Black Death of 1348–9. The English defeated the French in 1356 and Aquitaine came under English control in 1360. In 1429, Joan of Arc persuaded Charles VII to drive out the English from the country. Her successful relief of the siege of Orléans, on the Loire, was the turning point of the war.
