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.
History of France
A succession crisis following the death of the last direct Capetian monarch in 1328 led to the series of conflicts known as the Hundred Years' War between the House of Valois and the House of Plantagenet. The war formally began in 1337 following Philip VI's attempt to seize the Duchy of Aquitaine from its hereditary holder, Edward III of England, the Plantagenet claimant to the French throne. Despite early Plantagenet victories, including the capture and ransom of John II of France, fortunes turned in favor of the Valois later in the war. Among the notable figures of the war was Joan of Arc, a French peasant girl who led French forces against the English, establishing herself as a national heroine. The war ended with a Valois victory in 1453.
