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
King John of England inherited the Angevin domains from his brother Richard I. However, Philip II of France acted decisively to exploit the weaknesses of John, both legally and militarily, and by 1204 had succeeded in taking control of much of the Angevin continental possessions. Following John's reign, the Battle of Bouvines (1214), the Saintonge War (1242), and finally the War of Saint-Sardos (1324), the English king's holdings on the continent, as Duke of Aquitaine (Guyenne), were limited roughly to provinces in Gascony.
