Macdonald had played into the hands of his enemies the Campbells. Breadalbane and Argyle were at one in their determination to use their advantage, and they found a ready assistant in the Master of Stair, whose views, free from all local feeling, were of the sternest description, and who thought the Highlanders should be treated as uncivilized barbarians. He had been disappointed at the submission of the clans, and rejoiced at the opportunity of making one example. By his means the certificate granted by the sheriff appears to have been suppressed, and an order was drawn up and laid before William, in which, along with other instructions to the commander of the army in Scotland, were these words with regard to the clan of Glencoe: "It will be proper, for the vindication of public justice, to extirpate that set of thieves." William signed the order, probably without carefully reading it, almost certainly without understanding what Dalrymple meant by extirpation. His scheme was one of the utmost barbarity. A detachment of soldiers was sent into the glen as though on a friendly mission. They were kindly received and hospitably kept for more than a week. Then, at a fixed date, when other troops were to have stopped all the passes, they suddenly fell upon their kindly hosts and cruelly murdered them. The plan was but partially carried out. The passes had not been stopped, and not more than thirty-eight of the Highlanders were actually killed. But the villages were destroyed, the cattle driven off, and it is unknown how many more perished as they fled in the dead of winter in the wild mountains which surrounded their glen.
