raids into Normandy and again targeting Évreux. Richard countered Philip's thrust with a counterattack in Vexin, while Mercadier led a raid on Abbeville. By autumn 1198, Richard had regained almost all that had been lost in 1193. In desperate circumstances, Philip offered a truce so that discussions could begin towards a more permanent peace, with the offer that he would return all of the territories except for Gisors. In mid-January 1199, the two kings met for a final meeting, Richard standing on the deck of a boat, and Philip standing on the banks of the Seine River. Shouting terms at each other, they could not reach an agreement on the terms of a permanent truce, but they did agree to further mediation, which resulted in a five-year truce that held. Later in 1199, Richard was killed during a siege involving one of his vassals. Conflict with King John, 1200–1206 In May 1200, Philip signed the Treaty of Le Goulet with Richard's successor King John. The treaty was meant to bring peace to Normandy by settling the issue of its much-reduced boundaries. The terms of John's vassalage were not only for Normandy, but also for Anjou, Maine, and Touraine. John agreed to heavy terms, including the abandonment of all the English possessions in Berry and 20,000 marks of silver, while Philip in turn recognized John as king of England, formally abandoning Arthur of Brittany's candidacy, whom he had hitherto supported, recognizing instead John's suzerainty over the Duchy of Brittany. To seal the treaty, a marriage between Blanche of Castile, John's niece, and Louis the Lion, Philip's son, was contracted. This agreement did not bring warfare to an end in France, however, since John's mismanagement of Aquitaine led the province to later rebel in 1200, a disturbance that Philip secretly encouraged. To disguise his ambitions, Philip invited John to a conference at Andely and then entertained him at Paris, and both times he committed to complying with the treaty. In 1202, disaffected patrons petitioned the French king to summon John to answer their charges in his capacity as John's feudal lord in France. John refused to appear, so Philip again took up Arthur of Brittany's claims to the English throne as well as betrothing him to his six-year-old daughter Marie. In retaliation, John crossed over into Normandy and his forces soon captured Arthur. In 1203, Arthur disappeared, with most people believing that
