Its strength was to be roughly tested. On the revolt of the capital John Graham of Claverhouse, whose cruelties in the persecution of the Western Covenanters had been rewarded with high command in the Scotch army and with the title of Viscount Dundee, withdrew with a few troopers from Edinburgh to the Highlands and appealed to the clans. In the Highlands nothing was known of English government or misgovernment: all that the Revolution meant to a Highlander was the restoration of the House of Argyle. To many of the clans it meant the restoration of lands which had been granted them on the Earl's attainder; and the zeal of the Macdonalds, the Macleans, the Camerons, who were as ready to join Dundee in fighting the Campbells and the Government which upheld them as they had been ready to join Montrose in the same cause forty years before, was quickened by a reluctance to disgorge their spoil. They were soon in arms. William's Scotch regiments under General Mackay were sent to suppress the rising; but as they climbed the pass of Killiecrankie on the 27th of July 1689 Dundee charged them at the head of three thousand clansmen and swept them in headlong rout down the glen. His death in the moment of victory broke however the only bond which held the Highlanders together, and in a few weeks the host which had spread terror through the Lowlands melted helplessly away. In the next summer Mackay was able to build the strong post of Fort William in the very heart of the disaffected country, and his offers of money and pardon brought about the submission of the clans.
