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.
France–United Kingdom relations
Several of the most famous Anglo-French battles took place during the Hundred Years' War: Crécy, Poitiers, Agincourt, Orléans, Patay, Formigny and Castillon. The English under King Henry VIII invaded and defeated France in 1544-46. Major sources of French pride stemmed from their leadership during the war. Bertrand du Guesclin was a brilliant tactician who forced the English out of the lands they had procured at the Treaty of Brétigny, a compromising treaty that most Frenchmen saw as a humiliation. Joan of Arc was another unifying figure who to this day represents a combination of religious fervour and French patriotism to all France. After her inspirational victory at Orléans and what many saw as Joan's martyrdom at the hands of Burgundians and Englishmen, Jean de Dunois eventually forced the English out of all of France except Calais, which was only lost in 1558. Apart from setting national identities, the Hundred Years' War was the root of the traditional rivalry and at times hatred between the two countries. During this era, the English lost their last territories in France, except Calais, which would remain in English hands for another 105 years, though the English monarchs continued to style themselves as Kings of France until 1800.
