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]

Henry saw his own blunder as soon as it was made, and endeavoured to neutralize its effects by despatching an embassy to the Pope, requesting that he would send a legatine commission to settle the controversy. One of his envoys was the excommunicate John of Oxford; to the horror of Thomas and the indignation of Louis, John came back in triumph, boasting not only that he had been absolved by the Pope, but that two cardinals, William and Otto—the former of whom was a determined opponent of Thomas—were coming with full powers to sit in judgement on the case between primate and king and decide it without appeal.[284] The first half of the boast was true, but not the second; the cautious Pope instructed his envoys to do nothing more than arbitrate between the contending parties, if they could.[285] They did not reach Normandy till the autumn of 1167; Thomas came to meet them on the French border on November 18; he refused to enter upon any negotiations till the property of the metropolitan see was restored;[286] the legates carried their report to the king at Argentan, and were dismissed with an exclamation of disappointment and disgust—“I wish I may never set eyes upon a cardinal again!”[287] Five of the English bishops whom Henry had summoned to advise him renewed their appeal,[288] its original term having expired six months ago; and the legates insisting that Thomas should respect the appeal,[289] another year’s delay was gained.

At last, when the two kings made their treaty at Montmirail at Epiphany 1169, Thomas, who had come to the spot under the protection of Louis, suddenly entered the royal presence and fell at Henry’s feet, offering to place himself unreservedly in his hands. All parties thought the struggle was over, till the archbishop added once again the words which had so exasperated Henry at Oxford and at Clarendon: “Saving God’s honour and my order.” The king burst into a fury, and the meeting broke up in confusion.[290] Three months later, on Palm Sunday, from the high altar of Clairvaux, Thomas excommunicated ten of his opponents, first among whom was Gilbert Foliot.[291] Gilbert, who knew that the sentence had been hanging over him for more than a year, had appealed against it before it was uttered;[292] the king, too, was forewarned, and at every seaport guards were set to catch and punish with the utmost rigour any messenger from the primate. It was not till Ascension-day that a young layman named Berengar made his way up to the altar of Gilbert’s cathedral church in the middle of High Mass and thrust into the hand of the celebrant the archbishop’s letter proclaiming the excommunication of the bishop.[293] On that very day Thomas issued another string of excommunications.[294] Gilbert, driven to extremity, renewed his appeal two days later; and he added to it a formal refusal to acknowledge the jurisdiction of a metropolitan to whom he had made no profession, and a declaration—so at least it was reported in Gaul—of his intention to claim the metropolitical dignity for his own see, as an ancient right of which it had been unjustly defrauded by Canterbury.[295] A storm of indignant protest and vehement denunciation arose from the archbishop’s party; and the terrified Pope checked further proceedings by despatching another pair of envoys, who as usual failed to agree either with the king, with the archbishop, or even with each other, and after wasting the summer in misunderstandings and recriminations left the case just where they had found it.[296] By this time king and primate were both weary of their quarrel, and still more weary of mediation. In November they had another personal interview at Montmartre, and the archbishop’s unconditional restoration was all but decided.[297] Thomas, however, rashly attempted to hasten the completion of the settlement by a threat of interdict;[298] and the threat stung Henry into an act of far greater rashness. He had met Louis, as well as Thomas, at Montmartre, and had gained his immediate object of restraining the French king yet a little longer from direct hostilities; the settlement of Britanny was completed at Christmas, that of Aquitaine was so far secure that its conclusion might safely be left to Eleanor’s care; in March 1170 Henry went to England[299] with the fixed determination of seeing his eldest son crowned there before he left it again.

Three years before, he had wrung from the Pope—then blockaded in Rome by the Imperial troops, and in the last extremity of peril—a brief authorizing young Henry’s coronation by the archbishop of York, in default of the absent primate of all England.[300] In face of a mass of earlier and later rescripts from Alexander’s predecessors and Alexander himself, all strenuously confirming the exclusive privileges of Canterbury, Henry had never yet ventured to make use of this document; like Adrian’s bull for the conquest of Ireland, it had been kept in reserve for a future day; and that day had now come. In vain did Thomas proclaim his threatened interdict;[301] in vain did the Pope ratify it;[302] in vain did both alike issue prohibitions to all the English bishops against the act which they knew to be in contemplation.[303] The vigilance of the justiciars, quickened by a fresh set of stringent injunctions sent over by the king in the previous autumn,[304] made the delivery of letters from either primate or Pope so difficult that Thomas at last could intrust it to no one but a nun, Idonea, whom he solemnly charged with the duty of presenting to Roger of York the papal brief in which the coronation was forbidden.[305] The ceremony was fixed for Sunday, June 14. A week before that date young Henry, who with his girl-bride Margaret of France had been left at Caen under the care of his mother and Richard of Hommet the constable of Normandy, was summoned to join his father in England.[306] On S. Barnabas’s day the bishops and barons assembled at Westminster in obedience to the royal summons;[307] on Saturday, the 13th, the Pope’s letter was at last forced upon the archbishop of York;[308] but none the less did he on the following morning crown and anoint young Henry in Westminster abbey; while Gilbert of London, who had managed to extort conditional absolution in the Pope’s name from Archbishop Rotrou of Rouen,[309] once more stood openly by his side in the foremost rank of the English bishops.[310]

The elder king only waited to see the tenants-in-chief, with the king of Scots at their head, swear fealty to his new-made colleague ere he hurried back to Normandy to meet the fast-gathering storm.[311] Louis, incensed that his daughter’s husband should have been crowned without her, was already threatening war;[312] Thomas, seeing in the king’s action nothing but the climax of Canterbury’s wrongs, was overwhelming the Pope with complaints, reproaches, and intreaties for summary vengeance upon all who had taken part in the coronation; and the majority of the cardinals strongly supported his demands.[313] Henry saw that he must make peace at any price. Two days before the feast of S. Mary Magdalene he held a conference with Louis near Fréteval, on the borders of the Vendômois and the county of Chartres;[314] they were reconciled, and as they parted Henry said jestingly to the French king: “That rascal of yours, too, shall have his peace to-morrow; and a right good peace shall it be.”[315] At dawn on S. Mary Magalene’s day[316] he met Thomas in the “Traitor’s Meadow,”[317] close to Fréteval; they rode apart together, and remained in conference so long that the patience of their followers was all but exhausted, when at last Thomas was seen to dismount and throw himself at the king’s feet. Henry sprang from his horse, raised the archbishop from the ground, held his stirrup while he remounted, and rode back to tell his followers that peace was made, on terms which practically amounted to a complete mutual amnesty and a return to the state of affairs which had existed before the quarrel.[318]
