John meanwhile was summoning the earls and barons of England to meet him at Portsmouth at Whitsuntide (May 13), ready with horses and arms to accompany him over sea. The earls held a meeting at Leicester, and thence unanimously sent him word that they would not go with him “unless he gave them back their rights. For the king, following ill counsel, was demanding their castles of them; and beginning with William of Aubigny, he demanded of him the castle of Belvoir. William satisfied him by giving him his son as a hostage, and thus kept his castle.”[343] Notwithstanding their protest, the barons brought their forces to Portsmouth on the appointed day, equipped for a campaign, and each man provided with the money needful to cover his expenses during the usual term of service in a feudal host. This, and nothing more, was precisely what John wanted them to do: “He took from some of them the money which they would have spent in his service, and let them return home.”[344] The ready money which he thus obtained was a more useful and safer weapon for his purpose than the host itself would have been, and no pretext was left for the discussion of inconvenient questions. The king immediately despatched William the Marshal and Roger de Lacy, each at the head of a hundred mercenaries, “to check the assaults of his enemies on the borders of Normandy.” At the same time he appointed his chamberlain, Hubert de Burgh, warden of the Welsh marches, with another hundred soldiers under his command, and sent the bishop of Chester to William the Lion with a request that the term fixed for answering his demands might be extended to Michaelmas.[345] Having taken these precautions to secure England from attack, John again crossed the sea; on June 2 he was at Bonneville.[346] At the announcement of John’s intention to return, Philip had either compelled or persuaded the Lusignans to suspend hostilities in Poitou.[347] A period of negotiation followed; Philip remonstrating with John about his conduct towards the Lusignans, and urging him to make them restitution; John, in his turn, remonstrating with Philip for his constant aggressions and his interference with the internal affairs of John’s duchies. Several personal interviews seem to have taken place between the kings;[348] before the end of June the treaty of Ascension-tide 1200 was confirmed; and on the last day of that month John, by Philip’s invitation, went to Paris, and was there lodged and entertained for several days in the royal palace, which Philip vacated for his convenience.[349]
