Those who have visited that romantic spot need not be reminded of its peculiar features, for these, once seen, must dwell for ever in the memory. The lower part of the Pass is a stupendous mountain-chasm, scooped out by the waters of the Garry, which here descend in a succession of roaring cataracts and pools. The old road, which ran almost parallel to the river and close upon its edge, was extremely narrow, and wound its way beneath a wall of enormous crags, surmounted by a natural forest of birch, oak, and pine. An army cooped up in that gloomy ravine would have as little chance of escape from the onset of an enterprising partisan corps, as had the Bavarian troops when attacked by the Tyrolese in the steep defiles of the Inn. General Mackay, however, had made his arrangements with consummate tact and skill, and had calculated his time so well, that he was enabled to clear the Pass before the Highlanders could reach it from the other side. Advancing upwards, the passage becomes gradually broader, until, just below the House of Urrard, there is a considerable width of meadow-land. It was here that Mackay took up his position, and arrayed his troops, on observing that the heights above were occupied by the army of Dundee. The forces of the latter scarcely amounted to one-third of those of his antagonist, which were drawn up in line without any reserve. He was therefore compelled, in making his dispositions, to leave considerable gaps in his own line, which gave Mackay a further advantage. The right of Dundee's army was formed of the M'Lean, Glengarry, and Clanranald regiments, along with some Irish levies. In the centre was Dundee himself, at the head of a small and ill-equipped body of cavalry, composed of Lowland gentlemen and their followers, and about forty of his old troopers. The Camerons and Skyemen, under the command of Locheill and Sir Donald Macdonald of Sleat, were stationed on the left. During the time occupied by these dispositions, a brisk cannonade was opened by Mackay's artillery, which materially increased the impatience of the Highlanders to come to close quarters. At last the word was given to advance, and the whole line rushed forward with the terrific impetuosity peculiar to a charge of the clans. They received the fire of the regular troops without flinching, reserved their own until they were close at hand, poured in a murderous volley, and then, throwing away their firelocks, attacked the enemy with the broadsword.
