The King received this submission favourably, and summoned a great council of the clergy to meet at the Castle of Clarendon, by Salisbury. But when the council met, the Archbishop again insisted on the words 'saying my order;' and he still insisted, though lords entreated him, and priests wept before him and knelt to him, and an adjoining room was thrown open, filled with armed soldiers of the King, to threaten him. At length he gave way, for that time, and the ancient customs (which included what the King had demanded in vain) were stated in writing, and were signed and sealed by the chief of the clergy, and were called the Constitutions of Clarendon.

The quarrel went on, for all that. The Archbishop tried to see the King. The King would not see him. The Archbishop tried to escape from England. The sailors on the coast would launch no boat to take him away. Then, he again resolved to do his worst in opposition to the King, and began openly to set the ancient customs at defiance.

The King summoned him before a great council at Northampton, where he accused him of high treason, and made a claim against him, which was not a just one, for an enormous sum of money. Thomas a Becket was alone against the whole assembly, and the very Bishops advised him to resign his office and abandon his contest with the King. His great anxiety and agitation stretched him on a sick-bed for two days, but he was still undaunted. He went to the adjourned council, carrying a great cross in his right hand, and sat down holding it erect before him. The King angrily retired into an inner room. The whole assembly angrily retired and left him there. But there he sat. The Bishops came out again in a body, and renounced him as a traitor. He only said, 'I hear!' and sat there still. They retired again into the inner room, and his trial proceeded without him. By-and-by, the Earl of Leicester, heading the barons, came out to read his sentence. He refused to hear it, denied the power of the court, and said he would refer his cause to the Pope. As he walked out of the hall, with the cross in his hand, some of those present picked up rushes - rushes were strewn upon the floors in those days by way of carpet - and threw them at him. He proudly turned his head, and said that were he not Archbishop, he would chastise those cowards with the sword he had known how to use in bygone days. He then mounted his horse, and rode away, cheered and surrounded by the common people, to whom he threw open his house that night and gave a supper, supping with them himself. That same night he secretly departed from the town; and so, travelling by night and hiding by day, and calling himself 'Brother Dearman,' got away, not without difficulty, to Flanders.

The struggle still went on. The angry King took possession of the revenues of the archbishopric, and banished all the relations and servants of Thomas a Becket, to the number of four hundred. The Pope and the French King both protected him, and an abbey was assigned for his residence. Stimulated by this support, Thomas a Becket, on a great festival day, formally proceeded to a great church crowded with people, and going up into the pulpit publicly cursed and excommunicated all who had supported the Constitutions of Clarendon: mentioning many English noblemen by name, and not distantly hinting at the King of England himself.

When intelligence of this new affront was carried to the King in his chamber, his passion was so furious that he tore his clothes, and rolled like a madman on his bed of straw and rushes. But he was soon up and doing. He ordered all the ports and coasts of England to be narrowly watched, that no letters of Interdict might be brought into the kingdom; and sent messengers and bribes to the Pope's palace at Rome. Meanwhile, Thomas a Becket, for his part, was not idle at Rome, but constantly employed his utmost arts in his own behalf. Thus the contest stood, until there was peace between France and England (which had been for some time at war), and until the two children of the two Kings were married in celebration of it.
