In 1543, under the regency of the Earl of Arran, Donald _Dubh_, the grandson of John, last Lord of the Isles, again appeared upon the scene. Escaping from his long imprisonment, he was received with enthusiasm by the insular chiefs, and, with their assistance, he prepared to expel the Earls of Argyll and Huntly from their acquisitions in the Isles. At the head of 1800 men he invaded Argyll’s territories, slew many of his vassals, and carried off a great quantity of cattle, with other plunder. At first he was supported by the Earl of Lennox, then attached to the English interest, and thus remained for a time in the undisputed possession of the Isles. Through the influence of Lennox, the islanders agreed to transfer their alliance from the Scottish to the English crown, and in June 1545 a proclamation was issued by the regent Arran and his privy council against ‘Donald, alleging himself of the Isles, and other Highland men, his partakers.’ On the 28th July of that year, a commission was granted by Donald, ‘Lord of the Isles, and Earl of Ross,’ with the advice and consent of his barons and council of the Isles, of whom seventeen are named, to two commissioners, for treating, under the directions of the Earl of Lennox, with the English king. On the 5th of August, the lord and barons of the Isles were at Knockfergus, in Ireland, with a force of 4000 men and 180 galleys, when they took the oath of allegiance to the king of England, at the command of Lennox, while 4000 men in arms were left to guard and defend the Isles in his absence. Donald’s plenipotentiaries then proceeded to the English court with letters from him both to King Henry and his privy council; by one of which it appears that the Lord of the Isles had already received from the English monarch the sum of one thousand crowns, and the promise of an annual pension of two thousand. Soon after the Lord of the Isles returned with his forces to Scotland, but appears to have returned to Ireland again with Lennox. There he was attacked with fever, and died at Drogheda, on his way to Dublin. With him terminated the direct line of the Lords of the Isles. All hopes of a descendant of Somerled again governing the Isles were now at an end; and from this period the race of Conn, unable to regain their former united power and consequence, were divided into various branches, the aggregate strength of which was rendered unavailing for the purpose of general aggrandisement, by the jealousy, disunion, and rivalry, which prevailed among themselves.
