Sir John marched out of Edinburgh for the north on the very day that the standard of the Stuarts was erected in Glenfinnan, the 19th of August. On the following day he continued his route from Stirling, accompanied by one thousand five hundred foot, leaving, very properly, the dragoons behind him, as of no service in the mountains, nor capable of finding forage there. He then continued his march towards Fort Augustus, which he hoped to make the centre of his operations, and then to strike a sudden and annihilating blow on the handful of rebels. At Dalwhinnie he heard that the rebels now mustered six thousand, and that they meant to dispute the pass of Corriarrick, lying directly in the line of his march towards Fort Augustus. This Corriarrick had been made passable by one of General Wade's roads, constructed after the rebellion of 1715, to lay open the Highlands. The road wound up the mountain by seventeen zig-zags or traverses, and down the other side by others, called by the Highlanders the Devil's Staircase. Three hundred men were capable, much more three thousand, of stopping an army in such a situation, and Cope called a council of war. At length it was agreed that they should take a side route, and endeavour to reach Inverness and Fort George. The resolve was a fatal one, for it gave the appearance of a flight to the army, and left the road open to Stirling and the Lowlands. Charles, on his part, had determined to occupy Corriarrick. For that purpose he had made a forced march, disencumbered himself of all possible encumbrances by burning his own baggage, and encouraging his followers to do the same. On the morning of the 27th he stood on the north side of Corriarrick, and, as he put on his brogues, he is said to have exclaimed, with exultation, "Before these are unloosed, I shall be up with Mr. Cope." To his great astonishment, however, when he reached the summit all was one wild solitude--not a man was visible. At length they discerned some soldiers ascending, whom they set down for part of Lord Loudon's regiment, forming the English vanguard. They turned out to be only some deserters, who informed them of the change in Cope's route. At this news the Highlanders were filled with exuberant joy. They demanded permission to pursue and attack Cope's soldiers; but the chiefs saw too clearly the grand advantage offered them of descending suddenly into the Lowlands by the road thus left open. Whilst Sir John was making a forced march to Inverness, which he reached on the 29th of August, the Highlanders were descending like one of their own torrents southwards. In two days they traversed the mountains of Badenoch; on the third they reached the Vale of Athol.
