After some more stormy words the knights became irritated by Becket's contradictions, and swore "by God's wounds" that they had endured enough, but Becket, putting aside John of Salisbury's suggestion that he should speak privately to the angry knights, began to complain of the grievances and insults he had himself received during the preceding week: "They have attacked my servants," he said; "they have cut off my sumpter-mule's tail; they have carried off the casks of wine that were the King's own gift." To this Hugh de Moreville, who was the least aggressive of the four, replied: "Why did you not complain to the King of these outrages? Why did you take upon yourself to punish them by your own authority?" But Becket, turning sharply towards him, said: "Hugh! how proudly you lift up your head! When the rights of the Church are violated, I shall wait for no man's permission to avenge them. I will give to the King the things that are the King's, but to God the things that are God's. It is my business, and I alone will see to it." Taking up such an attitude in front of four men who had come hot-foot to Canterbury with the express determination to seek an excuse for killing him, Becket was sealing his own fate. For the first time in the interview the Archbishop had assumed an attitude of defiance; the fury of the knights broke at once through the bonds which had partially restrained it, and displayed itself openly in those impassioned gestures which are now confined to the half-civilized nations of the South and East, but which seem to have been natural to all classes of medieval Europe. Their eyes flashed fire, they sprang upon their feet, and, rushing close up to him, gnashed their teeth, twisting their long gloves, and wildly threw their arms above their heads. Fitzurse exclaimed: "You threaten us--you threaten us! are you going to excommunicate us all?" Becket sprang up from his couch at this insulting demonstration, and in the state of great excitement into which he could fall when roused, he flung down his defiant challenge that all the swords in England could not shake his obedience to the Pope. The four knights, goaded to fury by other passionate words, left him, shouting, "To arms! to arms!" They made their way with an excited throng to the great gateway, where they armed, while the doors were closed to shut off the monastery from communication with the town. The Archbishop seems to have been fully alive to his danger, and yet he persistently refused to take the smallest measure for his safety, opening with his own hands the door from the cloisters into the north transept which some of the monks had closed and barred immediately after they had dragged the Archbishop into the nearly dark building.
