Chivalry and Betrayal: The Hundred Years' War
In 1435 Bedford died and sworn enemies Charles VII and Phillip, Duke of Burgundy joined forces to get the English out and with Henry VI reluctance to wage war and to maintain peace by marrying Margaret of Anjou. Charles had no intention of peace and used cannon and sieges to retake France and Normandy culminating in the defeat of the English at the Battle of Castillon in the last English territory of Gascony ending 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).
