We may put aside at once all the wild talk of the archbishop’s biographers about plots against his life in which the king had a share. Even if Henry’s sudden willingness for his return was really suggested by words said to have been uttered by one of his counsellors—“Why keep the archbishop out of England? It would be far better to keep him in it”—there is no need to assume that those words bore even in the speaker’s mind, far less in that of the king, the horrible meaning which they were afterwards supposed to have covered;[332] for they were true in the most literal sense. The quarrel of king and primate would have mattered little had it been fought out on English ground; it was the archbishop’s exile which rendered him so dangerous. Thomas had dealt his most fatal blow at Henry by flying from him, and Henry, as he now perceived, had made his worst blunder in driving Thomas into France. Of the infinitely greater blunder involved in the archbishop’s murder—setting the criminal aspect of the deed altogether aside—it is enough to say that Henry was wholly incapable. The same may be said of Roger of York and Gilbert of London, although, like the king himself, they were urged by dread of the archbishop into making common cause with men of a very different stamp:—men who hated the primate with a far more intense personal hatred, and who were restrained by no considerations either of policy or of morality:—men such as Ralf de Broc, a ruffian adventurer who had served as the tool of Henry’s vengeance upon the archbishop’s kinsfolk, had resumed the custody of the archiepiscopal estates when it was resigned by Gilbert Foliot, had been for the last four years at once fattening upon the property of Thomas and smarting under his excommunication, and was ready to commit any crime rather than disgorge his ill-gotten gains.[333] It was known that Thomas had letters from the Pope suspending all those bishops who had taken part in the coronation of the young king, and replacing Gilbert of London, Jocelyn of Salisbury, and all whom Thomas had excommunicated under the sentences from which they had been irregularly released by some of the Papal envoys.[334] Gilbert, Jocelyn and Roger of York now hurried to Canterbury, intending to proceed to Normandy as soon as Thomas set foot in England; while Ralf de Broc, Reginald de Warren and Gervase of Cornhill the sheriff of Kent undertook to catch him at the moment of landing, ransack his baggage, search his person, and seize any Papal letters which he might bring with him. Thomas, however was warned; he sent the letters over before him, and the three prelates at Canterbury read their condemnation before their judge quitted Gaul.[335] Next day he sailed from Wissant, and on the morning of December 1 he landed at Sandwich.[336] His enemies were ready to receive him; but at the sight of John of Oxford they stopped short, and John in the king’s name forbade all interference with the primate.[337] Amid the rapturous greetings of the people who thronged to welcome their chief pastor, he rode on to Canterbury; there some of the royal officials came to him in the king’s name, demanding the absolution of the suspended and excommunicate bishops. Thomas at first answered that he could not annul a Papal sentence; but he afterwards offered to take the risk of doing so, if the culprits would abjure their errors in the form prescribed by the Church. Gilbert and Jocelyn were inclined to yield; but Roger refused, and they ended by despatching Geoffrey Ridel to enlist the sympathies of the young king in their behalf, while they themselves carried their protest to his father in Normandy.[338]

The young king was preparing to hold his Christmas court at Winchester.[339] Thomas proposed to join it, but was stopped in London by a peremptory command to “go back and mind his own business at Canterbury.”[340] He obeyed under protest, and on Christmas-day again excommunicated the De Brocs and their fellow-robbers.[341] The elder king was keeping the feast at his hunting-seat of Bures near Bayeux.[342] There the three bishops threw themselves at his feet; Roger of York spoke in the name of all, and presented the Papal letters;[343] the courtiers burst into a confused storm of indignation, but not one had any counsel to offer. In his impatience and disappointment Henry uttered the fatal words which he was to rue all his life: “What a parcel of fools and dastards have I nourished in my house, that none of them can be found to avenge me of this one upstart clerk!”[344]

The words were hardly more than he had used at Chinon four years before, but they fell now upon other ears. Four knights—Hugh de Morville, William de Tracy, Reginald Fitz-Urse and Richard le Breton[345]—took them as a warrant for the primate’s death. That night—it was Christmas-eve[346]—they vowed to slay him, no matter how or where;[347] they left the court in secret, crossed to England by different routes,[348] and met again at Saltwood, a castle which the archbishop had been vainly endeavouring to recover from the clutches of Ralf de Broc, and where Ralf himself was dwelling amid a crowd of his kinsfolk and dependents. There the final plot was laid.[349] How it was executed is a tale which has been told so often that its details may well be spared here. On the evening of December 29, after a scene in his own hall scarcely less disgraceful than the last scene in the king’s hall at Northampton, the primate of all England was butchered at the altar’s foot in his own cathedral church.[350]

The ill news travelled fast. It fell like a thunderbolt upon the Norman court still gathered round the king at Argentan,[351] whither the assembly had adjourned after the Christmas feast at Bures. Henry stood for a moment speechless with horror, then burst into a frenzy of despair, and shut himself up in his own rooms, refusing to eat or drink or to see any one.[352] In a few days more, as he anticipated, all Christendom was ringing with execration of the murder and clamouring for vengeance upon the king who was universally regarded as its instigator. The Pope ordered an interdict upon Henry’s continental dominions, excommunicated the murderers and all who had given or should henceforth give them aid, shelter or support, and was only restrained from pronouncing a like sentence upon the king himself by a promise that he would make compurgation and submit to penance.[353] Two cardinal-legates charged with the enforcement of these decrees were at once despatched to Normandy;[354] but when they arrived there, Henry was out of their reach. The death of Duke Conan in February had thrown Britanny completely into his hands; he only stayed to secure Geoffrey’s final establishment there as duke[355] before he called a council at Argentan and announced that he was going to Ireland.[356] He quitted Normandy just as the legates reached it,[357] leaving strict orders that the ports should be closed to all clerks and papal envoys, and that no one should dare to follow him without special permission.[358] Landing at Portsmouth in the first days of August,[359] he hurried to Winchester for a last interview with the dying Bishop Henry,[360] closed the English ports as he had closed those of Normandy,[361] then plunged once more into the depths of South Wales, and on October 16 sailed from Milford Haven for Waterford.[362]

The elements favoured his escape; for five months a persistent contrary wind hindered all communication to Ireland from any part of his dominions.[363] The bishops and the ministers were left to fight their own battles and make their own peace with the legates in Normandy until May 1172, when the king suddenly reappeared[364] to claim the papal absolution and offer in return not only his own spiritual obedience and that of his English and continental realms, but also that of Ireland, which he had secured for Rome as her share in the spoils of a conquest won with Adrian’s bull in his hand.[365] The bargain was soon struck. On Sunday May 21 Henry met the legates at Avranches, made his purgation for the primate’s death, promised the required expiation, and abjured his obnoxious “customs,” his eldest son joining in the abjuration.[366] To pacify Louis, young Henry and Margaret were sent over sea with the archbishop of Rouen and by him crowned together at Winchester on August 27;[367] and the Norman primate returned to join a great council of the Norman clergy assembled at Avranches to witness there, two days before Michaelmas, a public repetition of their sovereign’s purgation and his final absolution by the legates.[368]
