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 (1369–89)
The Treaty of Bruges was a treaty signed in 1375 between France and England in Bruges, present-day Belgium. The conference leading to the treaty was called at the instigation of Pope Gregory XI. France was represented in the negotiations by Philip II, Duke of Burgundy and England by John of Gaunt, 1st Duke of Lancaster. Negotiations broke down over the issue of sovereignty over the Aquitaine. The English wanted full sovereignty over Edward's territories, while the French insisted that the House of Valois
retain sovereignty of any Plantagenet provinces. Despite attempts by the Pope to broker a compromise, agreement could not be reached and the war resumed in 1377.
