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
Several overwhelming English victories in the war—especially at Crécy, Poitiers, and Agincourt—raised the prospects of an ultimate English triumph, and convinced the English to continue pouring money and manpower into the war over many decades. However, the greater resources of the French monarchy prevented the English kings from ever completing the conquest of France. Starting in 1429, decisive French victories at Orléans, Patay, Formigny, and Castillon concluded the war in favour of the House of Valois, with England permanently losing most of its possessions on the continent.
