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.
Truce of Espléchin
The Hundred Years' War had started in 1337. In 1340 Edward III of England, returned to France by sailing across the English Channel only to find his landing blocked by a large French and Genoese fleet at Sluys. The English won the resulting naval battle, which took place on 24 June 1340. The English navy was ably assisted by their allies, principally Flemings from Sluys and nearby Bruges who watched the fight from the shore and kept any French sailors from escaping.
