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.
Hundred Years' War
Edward invaded France, for the third and last time, hoping to capitalise on the discontent and seize the throne. The Dauphin's strategy was that of non-engagement with the English army in the field. However, Edward wanted the crown and chose the cathedral city of Reims for his coronation (Reims was the traditional coronation city). However, the citizens of Reims built and reinforced the city's defences before Edward and his army arrived. Edward besieged the city for five weeks, but the defences held and there was no coronation. Edward moved on to Paris, but retreated after a few skirmishes in the suburbs. Next was the town of Chartres. Disaster struck in a freak hailstorm on the encamped army, causing over 1,000 English deaths – the so-called Black Monday on Easter 1360. This devastated Edward's army and forced him to negotiate when approached by the French. A conference was held at Brétigny that resulted in the Treaty of Brétigny (8 May 1360). The treaty was ratified at Calais in October. In return for increased lands in Aquitaine, Edward renounced Normandy, Touraine, Anjou and Maine and consented to reduce King John's ransom by a million crowns. Edward also abandoned his claim to the crown of France.
