Having therefore settled peace here, he directed his march to Alclud, which Arthur had relieved from the oppression of barbarians, and from thence conducted his army to Mureif, where the Scots and Picts were besieged; after three several battles with the king and his nephew, they had fled as far as this province, and entering upon the lake Lumond, sought for refuge in the islands that are upon it. This lake contains sixty islands, and receives sixty rivers into it which empty themselves into the sea by no more than one mouth. There is also an equal number of rocks in these islands, as also of eagles' nests in those rocks, which flocked together there every year, and, by the loud and general noise which they now made, foreboded some remarkable event that should happen to the kingdom. To these islands, therefore, had the enemy fled, thinking the lake would serve them instead of a fortification; but it proved of little advantage to them. For Arthur, having got together a fleet, sailed round the rivers, and besieged the enemy fifteen days together, by which they were so straitened with hunger, that they died by thousands. While he was harassing them in this manner Guillamurius, king of Ireland, came up in a fleet with a very great army of barbarians, in order to relieve the besieged. This obliged Arthur to raise the siege, and turn his arms against the Irish, whom he slew without mercy, and compelled the rest to return back to their country. After this victory, he proceeded in his first attempt, which was to extirpate the whole race of the Scots and Picts, and treated them with an unparalleled severity. And as he allowed quarter to none, the bishops of that miserable country, with all the inferior clergy, met together, and bearing the reliques of the saints and other consecrated things of the church before them, barefooted, came to implore the king's mercy for their people. As soon as they were admitted into his presence, they fell down upon their knees, and humbly besought him to have pity on their distressed country, since the sufferings which he had already made it undergo were sufficient; nor was there any necessity to cut off the small remainder to a man; and that he would allow them the enjoyment of a small part of the country, since they were willing to bear the yoke which he should impose upon them. The king was moved at the manner of their delivering this petition, and could not forbear expressing his clemency to them with tears; and at the request of those holy men, granted them pardon. CHAP.
