There was another side to the treaty. Henry and Thomas met at Montmirail for the first time since the council of Northampton over four years before, to renew a quarrel in which no terms of peace were possible. The old hopeless dispute raged afresh, the king demanding a vow to obey the "customs of the kingdom," Thomas insisting on his clause "saving my order," "saving the honour of God." The former weary negotiations began again; new envoys hurried backwards and forwards; interminable letters argued the limits of the temporal and spiritual powers in phrases which lost nothing of their arrogance from the fact that neither side had the power to enforce their claims. The Primate would have no counsels. "Believe me," Thomas wrote of Henry, "who know the manners of the man, he is of such a disposition that nothing but punishment can mend." He excommunicated the bishops of London and Salisbury and a number of clerks and laymen, till in the chapel of the king there was scarcely one who was able to give him the kiss of peace. Henry "shook with fear," according to the boast of Thomas, at the excommunications. In vain the Pope sought to moderate his zeal. In the summer of 1169 two legates were sent to settle the dispute, of whom one was pledged to the king and the other to the archbishop. Henry, like every one else, saw the futility of their mission, and "led them for a week," as one of them complained, "through many windings both of road and speech." With a scornful taunt that "he did not care an egg for them and their excommunications," he finally mounted his horse to ride off from the conference. "I see, I see!" he said to the frightened bishops who hurried after him to call him back; "they will interdict my land, but surely I who can take the strongest of castles in any single day, shall I not avail to scotch a single clerk if he should interdict my land!" When a compromise seemed possible, he suddenly added to the form of peace he had proposed the words, "saving the dignity of my kingdom." This broke off all negotiations. "The dignity of the kingdom," said Thomas, "was only a softer name for the Constitutions of Clarendon." "If the king," said John of Salisbury, "had obtained the insertion of this clause, he had carried the royal customs, only changing the name." A new attempt at reconciliation was made in November at Montmartre, but Henry refused to give the Primate the "kiss of peace," which in feudal custom was the binding sign of perfect friendship; and when the Pope thought to compel his submission, first by threats and promises, then by a formal threat of interdict, he answered by despatching very decided orders to England. Anyone who carried an interdict to England was to suffer as a traitor; all clerks were summoned home from abroad; none might leave the kingdom without an order from the king; if any man should observe an interdict he was to be banished with all his kindred.
