The author of the Ardintoul MS. informs us that MacLean had actually invaded Ardnamurchan, and carried fire and sword into that and the adjoining territory of the Macdonalds, whereupon the Earl of Argyll, who claimed the Macdonalds of those districts as his vassals and dependants, obtained criminal letters against MacLean, who, finding this, sent for his brother-in-law, Mackenzie of Kintail, at whose request he had invaded the country of the Macdonalds. Both started for Inveraray. The Earl seemed most determined to punish MacLean, but Mackenzie informed him that "he should rather be blamed for it than MacLean, and the King and Council than either of them, for he having obtained, upon good grounds, a commission of fire and sword against Glengarry and such as would assist him, and against these men's rebellious and wicked courses, which frequently his lordship seemed to own, that he did charge, as he did several others of the king's loyal subjects, MacLean to assist him." So that, if Maclean was to be punished for acting as his friend and as a loyal subject, he hoped to obtain a hearing before the King and Council under whose orders he acted. After considerable discussion they parted good friends, Argyll having agreed not to molest MacLean any further. Mackenzie and MacLean returned to Duart, where his lordship was warmly received and sumptuously entertained by MacLean's immediate friends and kinsmen for the service which he had just rendered to their chief. While thus engaged, a messenger arrived at the castle from Mackenzie's lady and the Kintail men.
