On a sudden all was changed. The Revolution came. The heir of Argyle returned in triumph. He was, as his predecessors had been, the head, not only of a tribe, but of a party. The sentence which had deprived him of his estate and of his honours was treated by the majority of the Convention as a nullity. The doors of the Parliament House were thrown open to him: he was selected from the whole body of Scottish nobles to administer the oath of office to the new Sovereigns; and he was authorised to raise an army on his domains for the service of the Crown. He would now, doubtless, be as powerful as the most powerful of his ancestors. Backed by the strength of the Government, he would demand all the long and heavy arrears of rent and tribute which were due to him from his neighbours, and would exact revenge for all the injuries and insults which his family had suffered. There was terror and agitation in the castles of twenty petty kings. The uneasiness was great among the Stewarts of Appin, whose territory was close pressed by the sea on one side, and by the race of Diarmid on the other. The Macnaghtens were still more alarmed. Once they had been the masters of those beautiful valleys through which the Ara and the Shira flow into Loch Fyne. But the Campbells had prevailed. The Macnaghtens had been reduced to subjection, and had, generation after generation, looked up with awe and detestation to the neighbouring Castle of Inverary. They had recently been promised a complete emancipation. A grant, by virtue of which their chief would have held his estate immediately from the Crown, had been prepared, and was about to pass the seals, when the Revolution suddenly extinguished a hope which amounted almost to certainty, [326] The Macleans remembered that, only fourteen years before, their lands had been invaded and the seat of their chief taken and garrisoned by the Campbells, [327] Even before William and Mary had been proclaimed at Edinburgh, a Maclean, deputed doubtless by the head of his tribe, had crossed the sea to Dublin, and had assured James that, if two or three battalions from Ireland were landed in Argyleshire, they would be immediately joined by four thousand four hundred claymores, [328]
