Argyle in the meantime had fled to Edinburgh, to lay his complaints before the Convention of Estates. To meet the exigence of the moment, a considerable army was raised under General Baillie, a Presbyterian officer of skill and fidelity, with whom was joined in command the celebrated Sir John Urrie, a soldier of fortune like Dalgetty, who had already changed sides twice during the Civil War, and was destined to turn his coat a third time before it was ended. Argyle also, burning with indignation, proceeded to levy his own numerous forces, in order to avenge himself of his feudal enemy. He established his head-quarters at Dunbarton, where he was soon joined by a considerable force, consisting chiefly of his own clansmen and dependants. Being there joined by Baillie and Urrie, with a very considerable army of regular forces, he prepared to march into Argyleshire, and chastise the invader of his paternal territories.
But Montrose, while these two formidable armies were forming a junction, had been recalled from that ravaged country by the approach of a third, collected in the north under the Earl of Seaforth, who, after some hesitation, having embraced the side of the Covenanters, had now, with the assistance of the veteran garrison of Inverness, formed a considerable army, with which he threatened Montrose from Inverness-shire. Enclosed in a wasted and unfriendly country, and menaced on each side by advancing enemies of superior force, it might have been supposed that Montrose’s destruction was certain. But these were precisely the circumstances under which the active and enterprising genius of the Great Marquis was calculated to excite the wonder and admiration of his friends, the astonishment and terror of his enemies. As if by magic, he collected his scattered forces from the wasteful occupation in which they had been engaged; and scarce were they again united, ere Argyle and his associate generals were informed, that the royalists, having suddenly disappeared from Argyleshire, had retreated northwards among the dusky and impenetrable mountains of Lochaber.
The sagacity of the generals opposed to Montrose immediately conjectured, that it was the purpose of their active antagonist to fight with, and, if possible, to destroy Seaforth, ere they could come to his assistance. This occasioned a corresponding change in their operations. Leaving this chieftain to make the best defence he could, Urrie and Baillie again separated their forces from those of Argyle; and, having chiefly horse and Lowland troops under their command, they kept the southern side of the Grampian ridge, moving along eastward into the county of Angus, resolving from thence to proceed into Aberdeenshire, in order to intercept Montrose, if he should attempt to escape in that direction.
