About this time an incident, right common in that day, brought a number of noble young adventurers to the camp of Douglas. It chanced, in an encounter between two small rival parties at the back of the convent of Maisondieu, which stood on the south side of the Teviot, that Sir Thomas de Somerville of Carnwath engaged hand to hand with an English knight, named Sir Comes de Moubray, who, after a desperate encounter, unhorsed and wounded him. The affair was seen from the walls of Roxburgh, as well as by a part of the Scottish army which was encamped on a rising ground to the south, that overlooked the plain; and, of course, like all other chivalrous feats, became the subject of general conversation. Somerville was greatly mortified; and, not finding any other way to recover his honour, he sent a challenge to Moubray to fight him again before the gate of Roxburgh, in sight of both armies. Moubray was too gallant to refuse. There was not a knight in the castle who would have declined such a chance of earning fame, and recommending himself to his mistress and the fair in general. The challenge was joyfully accepted, and the two knights met in the midst of a circle of gentlemen appointed by both armies, on the castle green, that lay betwixt the moat and the river, immediately under the walls of the castle. Never was there a more gallant combat seen. They rode nine times against each other with full force, twice with lances and seven times with swords, yet always managed with such dexterity that neither were unhorsed, nor yet materially wounded. But at the tenth charge, by a most strenuous exertion, Sir Thomas disarmed and threw his opponent out of his saddle, with his sword-arm dislocated. Somerville gained great renown, and his fame was sounded in court and in camp. Other challenges were soon sent from both sides, and as readily accepted; and some of the best blood both of Scotland and England was shed in these mad chivalrous exploits. The ambition of the young Scottish nobles was roused, and many of them flocked as volunteers to the standard of Douglas. Among these were some of the retainers of Redhough, who could not resist such an opportunity of trying their swords with some rivals with whom they had erst exchanged sharp blows on the marches. Simon of Gemelscleuch, his cousin John of Howpasley, and the Laird of Yard-bire, all arrived in the camp of Douglas in one night, in order to distinguish themselves in these tilting bouts. Earl Douglas himself challenged Musgrave, hoping thereby to gain his end, and the prize for which he fought; but the knight, true to his engagement, sent him for answer, that he would first see the beginning of a new year, and then he should fight either him or any of his name, but that till then he had undertaken a charge to which all others must be subordinate.
