Hundred Years' War (1415–53)
By 1449, the French had retaken Rouen. In 1450 the Count of Clermont and Arthur de Richemont, Earl of Richmond, of the Montfort family (the future Arthur III, Duke of Brittany) caught an English army attempting to relieve Caen at the Battle of Formigny and defeated it. The English army was attacked from the flank and rear by Richemont's force just as they were on the verge of beating Clermont's army. The French proceeded to capture Caen on July 6 and Bordeaux and Bayonne in 1451. The attempt by Talbot to retake Guyenne, though initially welcomed by the locals, was crushed by Jean Bureau and his cannons at the Battle of Castillon in 1453 where Talbot had led a small Anglo-Gascon force in a frontal attack on an entrenched camp. This is considered the last battle of the Hundred Years' War.
Reims Campaign
The Reims Campaign took place during the Hundred Years' War. It occurred after the French de facto government rejected the terms of the Treaty of London and consequently Edward III of England organised and commanded an expeditionary army to gain by force what he had failed to win by diplomacy. On 28 October 1359 Edward landed at Calais, and advanced to Reims, where he hoped to be crowned king of France. The strenuous resistance of the citizens frustrated this scheme, and Edward marched into Burgundy, and then he made his way back towards Paris. Failing in an attack on the capital, he was glad to conclude, on 8 May 1360, preliminaries of peace at Brétigny, near Chartres. This treaty, less onerous to France than that of London, took its final form when Edward and John ratified the treaty in Calais on 9 October 1360. By it Edward renounced his claim to France in return for Aquitaine and other French territories in full sovereignty.
