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.
Congress of Arras
The Congress of Arras was a diplomatic congregation established at Arras in the summer of 1435 during the Hundred Years' War, between representatives of England, France, and Burgundy. Toward the close of the Hundred Years' War, both the Congress and the subsequent Treaty of Arras represented diplomatic failures for England and major successes for France.
