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.
Battle of Castillon
The term "Hundred Years' War" is misleading, as the fighting between the English and the French during the period of 1337 to 1453 was more a series of conflicts than a single prolonged war. Thus, the conflict(s) can be examined from the vantage point of various stages. The breakdown of the 1420 Treaty of Troyes began the final stage of the Hundred Years' War. This period from 1420 to 1453 is characterized by Anne Curry as the “wars of the Treaty of Troyes” for control of the crown of France.
