He stopped when he reached the railing and dismounted from his horse. It was against the laws of the combat for either party to enter the lists mounted. If a horse went within the inclosure he was forfeited by that act to a certain public officer called the high constable of England, who was responsible for the regularity and order of the proceedings. Anneslie, having thus dismounted from his horse with the assistance of his attendants, walked into the lists all armed and equipped for the fight. His squires attended him. He walked there to and fro a few minutes, and then a herald, blowing a trumpet, summoned the accused to appear. [Sidenote: Summons to the accused.] "Thomas Katrington! Thomas Katrington!" he cried out in a loud voice, "come and appear, to save the action for which Sir John Anneslie, knight, hath publicly and by writing appealed thee!" [Sidenote: Appearance of Katrington.] Three times the herald proclaimed this summons. At the third time Katrington appeared. He came, as Anneslie had come, mounted upon a war-horse splendidly caparisoned, and with his arms embroidered on the trappings. He was attended by his friends, the representatives of the seconds of the modern duel. The two stopped at the entrance of the lists, and dismounting, passed into the lists on foot. Every body being now intent on the combatants, the horse for the moment was let go, and, being eager to follow his master, he ran up and down along the railing, reaching his head and neck over as far as he could, and trying to get over. At length he was taken and led away; but the lord high constable said at once that he should claim him for having entered the lists. [Sidenote: Horse's head forfeited.] "At least," said he, "I shall claim his head and neck, and as much of him as was over the railing." [Sidenote: The pleadings.] The combatants now stood confronting each other within the lists. A written document was produced, which had been prepared, as was said, by consent of both parties, containing a statement of the charge made against Katrington, namely, that of treason, in having betrayed to the enemy for money a castle intrusted to his charge, and his reply. The herald read this document with a loud voice, in order that all the assembly, or as many as possible, might hear it. As soon as it was read, Katrington began to take exceptions to some passages in it. The Duke of Lancaster, who seemed to preside on the occasion, put an end to his criticisms at once, saying that he had already agreed to the paper, and that now, if he made any difficulty about it, and refused to fight, he should be adjudged guilty of the treason, and should at once be led out to execution. [Sidenote: Katrington is ready.]
