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 (1337–1360)
The Black Death had reached England in 1348. The widespread effects of the plague had effectively put the war on hold. However, by the mid-1350s the disease had receded sufficiently to allow the country to start rebuilding its finances. So in 1355 Edward's son, Edward the Black Prince, resumed the war and invaded France from English-held Gascony and by August of that year he had begun a brutal campaign of raids known as "chevauchée". This campaign was designed to terrorise and demoralise the people, discredit their leaders and drain the French king's financial resources. Anything that was portable was looted and anything that could not be taken away was broken or burnt. An observer at the time said, of the Black Prince, that "as he rode to Toulouse there was no town that he did not lay waste."
