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.
Three Hundred and Thirty Five Years' War
The origins of the war can be found in the English Civil War, fought between the Royalists and Parliamentarians from 1642 to 1651. Oliver Cromwell had fought the Royalists to the edges of the Kingdom of England. In the West of England this meant that Cornwall was the last Royalist stronghold. In 1648, Cromwell pushed on until mainland Cornwall was in the hands of the Parliamentarians.
