The death of the great Marquis of Montrose on the one side, the defeat at Inverlochy, and cruel plundering of Lorn, on the other, were reciprocal injuries not likely to be forgotten. Rob Roy was, therefore, sure of refuge in the country of the Campbells, both as having assumed their name, as connected by his mother with the family of Glenfalloch, and as an enemy to the rival house of Montrose. The extent of Argyle's possessions, and the power of retreating thither in any emergency, gave great encouragement to the bold schemes of revenge which he had adopted.

This was nothing short of the maintenance of a predatory war against the Duke of Montrose, whom he considered as the author of his exclusion from civil society, and of the outlawry to which he had been sentenced by letters of horning and caption (legal writs so called), as well as the seizure of his goods, and adjudication of his landed property. Against his Grace, therefore, his tenants, friends, allies, and relatives, he disposed himself to employ every means of annoyance in his power; and though this was a circle sufficiently extensive for active depredation, Rob, who professed himself a Jacobite, took the liberty of extending his sphere of operations against all whom he chose to consider as friendly to the revolutionary government, or to that most obnoxious of measures—the Union of the Kingdoms. Under one or other of these pretexts, all his neighbours of the Lowlands who had anything to lose, or were unwilling to compound for security by paying him an annual sum for protection or forbearance, were exposed to his ravages.

The country in which this private warfare, or system of depredation, was to be carried on, was, until opened up by roads, in the highest degree favourable for his purpose. It was broken up into narrow valleys, the habitable part of which bore no proportion to the huge wildernesses of forest, rocks, and precipices by which they were encircled, and which was, moreover, full of inextricable passes, morasses, and natural strengths, unknown to any but the inhabitants themselves, where a few men acquainted with the ground were capable, with ordinary address, of baffling the pursuit of numbers.

The opinions and habits of the nearest neighbours to the Highland line were also highly favourable to Rob Roy's purpose. A large proportion of them were of his own clan of MacGregor, who claimed the property of Balquhidder, and other Highland districts, as having been part of the ancient possessions of their tribe; though the harsh laws, under the severity of which they had suffered so deeply, had assigned the ownership to other families. The civil wars of the seventeenth century had accustomed these men to the use of arms, and they were peculiarly brave and fierce from remembrance of their sufferings. The vicinity of a comparatively rich Lowland district gave also great temptations to incursion. Many belonging to other clans, habituated to contempt of industry, and to the use of arms, drew towards an unprotected frontier which promised facility of plunder; and the state of the country, now so peaceable and quiet, verified at that time the opinion which Dr. Johnson heard with doubt and suspicion, that the most disorderly and lawless districts of the Highlands were those which lay nearest to the Lowland line. There was, therefore, no difficulty in Rob Roy, descended of a tribe which was widely dispersed in the country we have described, collecting any number of followers whom he might be able to keep in action, and to maintain by his proposed operations.

He himself appears to have been singularly adapted for the profession which he proposed to exercise. His stature was not of the tallest, but his person was uncommonly strong and compact. The greatest peculiarities of his frame were the breadth of his shoulders, and the great and almost disproportionate length of his arms; so remarkable, indeed, that it was said he could, without stooping, tie the garters of his Highland hose, which are placed two inches below the knee. His countenance was open, manly, stern at periods of danger, but frank and cheerful in his hours of festivity. His hair was dark red, thick, and frizzled, and curled short around the face. His fashion of dress showed, of course, the knees and upper part of the leg, which was described to me, as resembling that of a Highland bull, hirsute, with red hair, and evincing muscular strength similar to that animal. To these personal qualifications must be added a masterly use of the Highland sword, in which his length of arm gave him great advantage—and a perfect and intimate knowledge of all the recesses of the wild country in which he harboured, and the character of the various individuals, whether friendly or hostile, with whom he might come in contact.

His mental qualities seem to have been no less adapted to the circumstances in which he was placed. Though the descendant of the blood-thirsty Ciar Mhor, he inherited none of his ancestor's ferocity. On the contrary, Rob Roy avoided every appearance of cruelty, and it is not averred that he was ever the means of unnecessary bloodshed, or the actor in any deed which could lead the way to it. His schemes of plunder were contrived and executed with equal boldness and sagacity, and were almost universally successful, from the skill with which they were laid, and the secrecy and rapidity with which they were executed. Like Robin Hood of England, he was a kind and gentle robber,—and, while he took from the rich, was liberal in relieving the poor. This might in part be policy; but the universal tradition of the country speaks it to have arisen from a better motive. All whom I have conversed with, and I have in my youth seen some who knew Rob Roy personally, give him the character of a benevolent and humane man "in his way."

His ideas of morality were those of an Arab chief, being such as naturally arose out of his wild education. Supposing Rob Roy to have argued on the tendency of the life which he pursued, whether from choice or from necessity, he would doubtless have assumed to himself the character of a brave man, who, deprived of his natural rights by the partiality of laws, endeavoured to assert them by the strong hand of natural power; and he is most felicitously described as reasoning thus, in the high-toned poetry of my gifted friend Wordsworth:

Say, then, that he was wise as brave, As wise in thought as bold in deed; For in the principles of things He sought his moral creed. Said generous Rob, "What need of Books? Burn all the statutes and their shelves! They stir us up against our kind, And worse, against ourselves. "We have a passion, make a law, Too false to guide us or control; And for the law itself we fight In bitterness of soul. "And puzzled, blinded, then we lose Distinctions that are plain and few; These find I graven on my heart, That tells me what to do. "The creatures see of flood and field, And those that travel on the wind With them no strife can last; they live In peace, and peace of mind. "For why? Because the good old rule Sufficeth them; the simple plan, That they should take who have the power, And they should keep who can. "A lesson which is quickly learn'd, A signal through which all can see; Thus, nothing here provokes the strong To wanton cruelty. "And freakishness of mind is check'd, He tamed who foolishly aspires, While to the measure of his might Each fashions his desires. "All kinds and creatures stand and fall By strength of prowess or of wit; 'Tis God's appointment who must sway, And who is to submit. "Since then," said Robin, "right is plain, And longest life is but a day, To have my ends, maintain my rights, I'll take the shortest way." And thus among these rocks he lived, Through summer's heat and winter's snow The eagle, he was lord above, And Rob was lord below.

We are not, however, to suppose the character of this distinguished outlaw to be that of an actual hero, acting uniformly and consistently on such moral principles as the illustrious bard who, standing by his grave, has vindicated his fame. On the contrary, as is common with barbarous chiefs, Rob Roy appears to have mixed his professions of principle with a large alloy of craft and dissimulation, of which his conduct during the civil war is sufficient proof. It is also said, and truly, that although his courtesy was one of his strongest characteristics, yet sometimes he assumed an arrogance of manner which was not easily endured by the high-spirited men to whom it was addressed, and drew the daring outlaw into frequent disputes, from which he did not always come off with credit. From this it has been inferred, that Rob Roy was more of a bully than a hero, or at least that he had, according to the common phrase, his fighting days. Some aged men who knew him well, have described him also as better at a taich-tulzie, or scuffle within doors, than in mortal combat. The tenor of his life may be quoted to repel this charge; while, at the same time, it must be allowed, that the situation in which he was placed rendered him prudently averse to maintaining quarrels, where nothing was to be had save blows, and where success would have raised up against him new and powerful enemies, in a country where revenge was still considered as a duty rather than a crime. The power of commanding his passions on such occasions, far from being inconsistent with the part which MacGregor had to perform, was essentially necessary, at the period when he lived, to prevent his career from being cut short.

I may here mention one or two occasions on which Rob Roy appears to have given way in the manner alluded to. My late venerable friend, John Ramsay of Ochtertyre, alike eminent as a classical scholar and as an authentic register of the ancient history and manners of Scotland, informed me, that on occasion of a public meeting at a bonfire in the town of Doune, Rob Roy gave some offence to James Edmondstone of Newton, the same gentleman who was unfortunately concerned in the slaughter of Lord Rollo (see Maclaurin's Criminal Trials, No. IX.), when Edmondstone compelled MacGregor to quit the town on pain of being thrown by him into the bonfire.
