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.
Hundred Years' War
The war owes its historical significance to multiple factors. By its end, feudal armies had been largely replaced by professional troops, and aristocratic dominance had yielded to a democratisation of the manpower and weapons of armies. Although primarily a dynastic conflict, the war gave impetus to ideas of French and English nationalism. The wider introduction of weapons and tactics supplanted the feudal armies where heavy cavalry had dominated, and artillery became important. The war precipitated the creation of the first standing armies in Western Europe since the time of the Western Roman Empire, thus helping to change their role in warfare. With respect to the belligerents, in France, civil wars, deadly epidemics, famines, and bandit free-companies of mercenaries reduced the population drastically. In England, political forces over time came to oppose the costly venture. The dissatisfaction of English nobles, resulting from the loss of their continental landholdings, as well as the general shock at losing a war in which investment had been so great, became factors leading to the Wars of the Roses (1455–1487).
