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.
History of weapons
The Hundred Years' War was a series of big and small wars fought between France and England from 1337 to 1453. In the year 1337, the French King Philip VI demanded that the provinces under the English rule, Gascony and Guyenne be given back to the French. However, English king, Edward III denied this demand which led to a war between the two. The English had their eyes on the wool industry in Flanders, moreover they had a stable government and efficient soldiers ready to fight the French. During this period, most of the Europeans armies relied mainly on infantry, the infantry dominated armies were taking a toll on cavalry dominated armies. Digging ditches, constructing wagon fortresses, or flooding already marshy
ground, so that the enemy could attack from only one direction, were some of the methods employed by both the armies during the Hundred Years' War. In the final phase of the war, gunpowder was also used for the first time in Western Europe. Jean and Gaspard Bureau's effective organization of artillery weapons enabled the French army in open battlefields as well as siege warfare. At Castillon, the French army annihilated the English, effectively using cannons, handguns and heavy cavalry.
