The French host was summoned to meet at Bourges on 17th May.[1171] The chief English seaports were bidden to send all their ships to Portsmouth so as to be there on 30th May ready to go forth “on the King’s service.”[1172] But Henry’s project met with an unexpected check. Louis had made it a condition of his Albigensian crusade that the Pope should forbid Henry, on pain of excommunication, to molest him or his realm in any way while he was thus engaged;[1173] and this, on 27th April, Honorius did.[1174] When his letter reached England, the King called his counsellors together and asked them what they advised him to do in the face of this prohibition. They were all of one mind that his cherished scheme must be deferred “till it should be seen what would become of the French King, who had undertaken such a difficult work and costly enterprise.” Henry’s anxiety about his brother was presently allayed by the arrival of letters from Richard giving a good report of his successes. “Moreover there was then among the King’s counsellors one Master William surnamed Pierepunt, skilled in astronomy, who constantly affirmed before the King that if the King of France proceeded with the expedition which he had begun, he would either never return alive, or suffer a great loss and overthrow. The King therefore, cheered by hearing these things, acquiesced in the counsel of his friends.”[1175] On 23rd June the fleet was dismissed,[1176] and so far as Poitou was concerned, fighting and negotiation were alike at a standstill for the next four months.
