On July 27, at Blair, Dundee learned that Mackay’s force had already entered the steep and narrow pass of Killiecrankie, where the road skirted the brawling waters of the Garry. Dundee had not time to defend the pass; he marched his men from Blair, keeping the heights, while Mackay emerged from the gorge, and let his forces rest on the wide level haugh beside the Garry, under the house of Runraurie, now called Urrard, with the deep and rapid river in their rear. On this haugh the tourist sees the tall standing stone which, since 1735 at least, has been known as “Dundee’s stone.” From the haugh rises a steep acclivity, leading to the plateau where the house of Runraurie stood. Mackay feared that Dundee would occupy this plateau, and that the fire thence would break up his own men on the haugh below. He therefore seized the plateau, which was an unfortunate manoeuvre. He was so superior in numbers that both of his wings extended beyond Dundee’s, who had but forty ill-horsed gentlemen by way of cavalry. After distracting Mackay by movements along the heights, as if to cut off his communications with the south, Dundee, who had resisted the prayers of the chiefs that he would be sparing of his person, gave the word to charge as the sun sank behind the western hills. Rushing down hill, under heavy fire and losing many men, the clans, when they came to the shock, swept the enemy from the plateau, drove them over the declivity, forced many to attempt crossing the Garry, where they were drowned, and followed, slaying, through the pass. Half of Hastings’ regiment, untouched by the Highland charge, and all of Leven’s men, stood their ground, and were standing there when sixteen of Dundee’s horse returned from the pursuit. Mackay, who had lost his army, stole across the Garry with this remnant and made for Stirling. He knew not that Dundee lay on the field, dying in the arms of Victory. Precisely when and in what manner Dundee was slain is unknown; there is even a fair presumption, from letters of the English Government, that he was murdered by two men sent from England on some very secret mission. When last seen by his men, Dundee was plunged in the battle smoke, sword in hand, in advance of his horse.
When the Whigs—terrified by the defeat and expecting Dundee at Stirling with the clans and the cavaliers of the Lowlands—heard of his fall, their sorrow was changed into rejoicing. The cause of King James was mortally wounded by the death of “the glory of the Grahams,” who alone could lead and keep together a Highland host. Deprived of his leadership and distrustful of his successor, General Cannon, the clans gradually left the Royal Standard. The Cameronian regiment, recruited from the young men of the organised societies, had been ordered to occupy Dunkeld. Here they were left isolated, “in the air,” by Mackay or his subordinates, and on August 21 these raw recruits, under Colonel Cleland, who had fought at Drumclog, had to receive the attack of the Highlanders. Cleland had fortified the Abbey church and the “castle,” and his Cameronians fired from behind walls and from loopholes with such success that Cannon called off the clansmen, or could not bring them to a second attack: both versions are given. Cleland fell in the fight; the clans disbanded, and Mackay occupied the castle of Blair.
