Accordingly, in the summer of 1187, all the military force of Scotland which had not openly declared for Mac William, was ordered to concentrate upon Inverness; and William contemplated placing himself at the head of his army, following his rival into the remoter Highlands, and forcing him to a decisive contest, about the result of which he entertained little doubt. Many of his barons, however, who were alive to the dangers of the impending campaign in a wild and mountainous region, vehemently opposed the royal project, dreading the repetition of some disastrous accident from the fiery and impetuous courage of the king. They were uneasy, also, about the fidelity of a certain portion of the royal army, who were quite as well inclined to favour Mac William as to support the cause of the king; and, acquiescing at length in the prudence of their advice, William consented to remain at Inverness, and to entrust the immediate conduct of the war to leaders upon whose ability and fidelity he could depend. A fresh difficulty arose, after the king’s decision, from the positive refusal of some of his principal nobles to march without the king against Mac William. At a moment of such vital importance to the royal cause, when the exertions of the well-affected were paralysed by this unexpected sedition, the eyes of all the army were turned upon the Lord of Galloway; and it was well for William that, in this crisis, he could count upon the fidelity of that powerful baron.[444] No hesitation marked the conduct of Roland, who at once threw the whole weight of his influence and authority upon the side of his royal master; and when, in consequence of the dispute, it was arranged that the main body of the army should remain with William at Inverness, placing himself at the head of three thousand of his own followers, upon whose fidelity he could depend, he set out in search of Mac William, in the determination of carrying out in person the original intentions of the king. The fate of Scotland was decided by an accident; and it has twice been the destiny of Inverness to witness, in its vicinity, the termination of a contest for a crown. Upon the moor of Mamgarvy, some long forgotten spot in that neighbourhood, the party of Roland unexpectedly fell in with a body of the enemy, whose numbers were about equal to their own. Neither party shunned the contest, but the royalists gained the day, and amongst the slain was discovered the lifeless body of Mac William. His death terminated the war, and the victor returned in triumph to Inverness, to earn the grant of the broad lands of Galloway with the head of his royal master’s most formidable and inveterate opponent.[445]
