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.
Truce of Leulinghem
The Truce of Leulinghem was a truce agreed to by Richard II's kingdom of England and its allies, and Charles VI's kingdom of France and its allies, on 18 July 1389, ending the second phase of the Hundred Years' War. England was on the edge of financial collapse and suffering from internal political divisions. On the other side, Charles VI was suffering from a mental illness that handicapped the furthering of the war by the French government. Neither side was willing to concede on the primary cause of the war, the legal status of the Duchy of Aquitaine and the King of England's homage to the King of France through his possession of the duchy. However, both sides faced major internal issues that could badly damage their kingdoms if the war continued. The truce was originally negotiated by representatives of the kings to last three years, but the two kings met in person at Leulinghem, near the English fortress of Calais, and agreed to extend the truce to a twenty-seven years' period. Other provisions were agreed to, in attempts to bring an end to the papal schism, to launch a joint crusade against the Turks in the Balkans, to seal the marriage of Richard to Charles' daughter Isabella along with an 800,000 franc dowry, and to guarantee to continue peace negotiations, in order to establish a lasting treaty between the kingdoms. The treaty brought peace to the Iberian peninsula, where Portugal and Castile were supporting the English and French respectively. The English evacuated all their holdings in northern France except Calais.
