During the year 1211 a new insurrection broke out in Ross, headed by Guthred or Godfrey, the son of Donald Bane or MacWilliam, as he was called. Great depredations were committed by the insurgents, who were chiefly freebooters from Ireland, the Hebrides, and Lochaber. For a long time they baffled the king’s troops; and although the king built two forts to keep them in check, and took many prisoners, they maintained for a considerable period a desultory and predatory warfare. Guthred even forced one of the garrisons to capitulate, and burnt the castle; but being betrayed by his followers into the hands of William Comyn, Earl of Buchan, the Justiciary of Scotland, he was executed in the year 1212. Shortly after the accession of Alexander II. in 1214, the peace of the north was attempted to be disturbed by Donald MacWilliam, who made an inroad from Ireland into Moray; but he was repulsed by the tribes of that country, led by M’Intagart, the Earl of Ross. In 1222, notwithstanding the formidable obstacles which presented themselves from the nature of the country, Alexander carried an army into Argyle, for the purpose of enforcing the homage of the western chiefs. His presence so alarmed the men of Argyle, that they immediately made their submission. Several of the chiefs fled for safety, and to punish them, the king distributed their lands among his officers and their followers. After this invasion Argyle was brought under the direct jurisdiction of the Scottish king, although the descendants of the race of Somerled, Lord of the Isles, still continued to be the chief magnates. During the same year a tumult took place in Caithness, on account of the severity with which the tithes were exacted by Adam, the bishop, who, with his adviser, Serlo, was murdered by the bonders. The king, who was at the time at Jedburgh, hearing of this murder, immediately hastened to the north with a military force, and inflicted the punishment of death upon the principal actors in this tragedy, who amounted, it is said, to four hundred persons; and that their race might become extinct, their children were emasculated, a practice very common in these barbarous times. The Earl of Caithness, who was supposed to have been privy to the murder, was deprived of half of his estate, which was afterwards restored to him on payment of a heavy fine. The Earl is said to have been murdered by his own servants in the year 1231, and in order to prevent discovery, they laid his body into his bed and set fire to the house.
