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.
Second Hundred Years' War
The French military rivalry continued with British opposition of the French Revolution and the ensuing wars with first the new French Republic and then the Empire of Napoleon. His defeat in 1814 was followed by his abdication and exile, but he escaped the following year to begin the Hundred Days. These came to a close with his military disaster at the Battle of Waterloo, facing an Allied force commanded by the Duke of Wellington. The end of the Napoleonic Wars effectively ended the recurrent conflict between France and Britain. However, Britain and her allies' goal of restoring the French Bourbon monarchy in the Treaty of Paris and the subsequent Congress of Vienna, which sought to prevent further revolutions in Europe, ultimately failed with the later Revolutions of 1848.
