The news of these proceedings reached Henry when, sick and anxious, he was trying to gather up strength and energy for a campaign against the Bretons. He instantly despatched another messenger to England, bidding Richard de Lucy call an assembly of the bishops and clergy and compel them to make a general appeal to the Pope against the authority and jurisdiction of their primate.[274] The meeting was held in London[275] at midsummer.[276] The appeal was made and sent to the Pope in the name of all the bishops and clergy of England; but it is tolerably clear that the main body were merely passive followers, more or less willing, of Gilbert of London and Jocelyn of Salisbury, the former of whom was almost certainly the writer of the letter which conveyed the appeal to the Pope, as well as of that which announced it to the primate.[277] The hand of Gilbert Foliot was indeed so plainly visible that Thomas’s reply was addressed with equal plainness to him personally.[278] The long and sarcastic letter with which he retorted[279] was answered in a yet more startling fashion at the opening of the next year. As Gilbert stood before the high altar of his cathedral church on the feast of its patron saint a paper was thrust into his hand; to his dismay it proved to be a papal brief granting to Archbishop Thomas a commission as legate for all England, and commanding the bishops to render him unqualified obedience and to resign within two months whatever confiscated church property had been placed in their charge by the king. In an agony of distress Gilbert, who himself had the custody of the Canterbury estates, sent this news to the king, imploring him to grant permission that the Pope’s mandate might be obeyed, at least till some method could be devised for escaping from a dilemma which now looked well-nigh hopeless.[280] Henry, absorbed in a struggle with the Bretons, had already been provoked into a vengeance as impolitic as it was mean. He threatened the Cistercian abbots assembled on Holy Cross day at the general chapter of their order that if Thomas were not immediately expelled from Pontigny, he would send all the White Monks in his dominions to share the primate’s exile.[281] When the abbot of Pontigny carried this message home, Thomas could only bid him farewell and betake himself to the sole protection left him--that of the king of France. He left Pontigny on S. Martin’s day[282] 1166, and took up his abode as the guest of Louis in the abbey of S. Columba at Sens.[283] [274] Gerv. Cant. (Stubbs), vol. i. p. 200. [275] Gerv. Cant.
