Some months before the period of redemption had expired, Rob Roy, aware of the danger to which his ward was exposed, raised a sum of money in order to redeem the pledge. It was pretended by the creditor, that the bond securing the power of redemption was lost; and since a few months only of the period remained, a plan was formed by him for protracting the settlement of the affair. Rob Roy, unhappily, was elsewhere occupied: the period expired; the young Macgregor ceased, therefore, to be the proprietor of his estate; he was ordered to leave it, and to remove his attendants, cattle, and tenants within eight days. "But law," as Dr. Johnson observes, "is nothing without power." Before those eight days had elapsed, Rob Roy had assembled his gillies, had followed his creditor into Argyleshire, had met him, nevertheless, in Strathfillan, and had carried him prisoner to an inn. There the unjust creditor was desired to give up the bond, and told to send for it from his castle. The affrighted man promised all that could be required of him; Rob Roy would not trust him, but sent two of his followers for the bond, which was brought at the end of two days. When it was delivered to Macgregor, he refused to pay the sum of redemption, telling the creditor that the money was too small a fine for the wrong which he had inflicted; and that he might be thankful to escape as well as he might.

Against all acts of oppression, except those which he thought proper to commit himself, Rob Roy waged war. He was the avenger of the injured, and the protector of the humble; and lest his own resources should prove insufficient for these purposes, a contract was entered into with several neighbouring proprietors to combine, for the purposes of defence, and protection to others.

The Duke of Montrose and his agent, Graham of Killearn, were still the especial objects of Macgregor's hatred. When a widow was persecuted by the merciless factor, and distrained for rent, Rob Roy intercepted the officers who went out against her, and gave them a severe chastisement; and a similar excursion was made in favour of any poor man who was obliged to pay a sum of money for rent. The collectors of the rent were disarmed, and obliged to refund what they had received. Upon the same principle of might against right, Rob Roy supported his family and retainers upon the contents of a meal-store which Montrose kept at a place called Moulin; and when any poor family in the neighbourhood were in want of meat, Rob Roy went to the store-keeper, ordered the quantity which he wanted, and directed the tenants to carry it away. There was no power either of resistance or complaint. If the parks of Montrose were cleared of their cattle, the Duke was obliged to bear the loss in silence. At length, harassed by constant depredations, Montrose applied to the Privy Council for redress, and obtained the power of pursuing and repressing robbers, and of recovering the goods stolen by them. But, in this act, such was the dread of Rob Roy's power, that his name was intentionally omitted in the order in Council.

The retreat into which Rob Roy retired, in times of danger, was a cave at the base of Ben Lomond, and on the borders of the Loch. The entrance to this celebrated recess is extremely difficult from the precipitous heights which surround it. Mighty fragments of rock, partially overgrown with brushwood and heather, guard the approach. Here Robert de Bruce sheltered himself from his enemies; and here Rob Roy, who had an enthusiastic veneration for that monarch, believed that he was securing to himself an appropriate retirement. It was, indeed, inaccessible to all but those who knew the rugged entrance; and here, had it not been for the projects which brought the Chevalier St. George to England, Rob Roy might have defied, during his whole lifetime, the vengeance of Montrose. From this spot Macgregor could almost command the whole country around Loch Lomond; a passionate affection to the spot became the feeling, not only of his mind, but of that of his wife, who, upon being compelled to quit the banks of Loch Lomond, gave way to her grief in a strain which obtained the name of "Rob Roy's Lament."

Of the exquisite beauty, and of the grandeur and interest of the scene of Rob Roy's seclusion, thousands can now form an estimate. Dr. Johnson was no enthusiast when he thus coldly and briefly adverted to the characteristics of Loch Lomond. "Had Loch Lomond been in a happier climate, it would have been the boast of wealth and vanity to own one of the little spots which it incloses, and to have employed upon it all the arts of embellishment. But as it is, the islets which court the gazer at a distance, disgust him at his approach, when he finds instead of soft lawns and shady thickets, nothing more than uncultivated ruggedness."[112]

From this retreat Rob Roy frequently emerged upon some mission of destruction, or some errand of redress. His name was a terror to all who had ever incurred his wrath; his depredations were soon extended to the Lowlands. One night a report prevailed in Dumbarton, that Rob Roy intended to surprise the militia and to fire the town. It was resolved to anticipate this attack, and accordingly the militia made their way to Craig Royston; and having secured the boats on Loch Lomond, which belonged to the Macgregors, they proceeded to seek for Rob Roy. But the chieftain had collected his followers, and, retreating into his cave, he laughed at his enemies, who were forced to retire without encountering him, the object of their search.

It is indeed remarkable, that outrages so audacious, and a power so imperative as that of Rob Roy, should have defied all control within forty miles of the city of Glasgow, an important and commercial city. "Thus," as Sir Walter Scott observes, "a character like his, blending the wild virtues, the subtle policy, and unconstrained licence of an American Indian, was flourishing in Scotland during the Augustan age of Queen Anne and George the First. Addison, it is probable, and Pope, would have been considerably surprised if they had known that there existed, in the same island with them, a personage of Rob Roy's peculiar habits and profession."

To the various other traits in the character of Rob Roy, there was added that tenacity of purpose, that obstinate and indefatigable hatred, which were common to the Highlanders. Their feuds were, it is true, hereditary, and were implanted in their minds before the reason could calm the passions. The fierce, implacable temper of the Macgregors had been aggravated by long-standing injuries and insults; among those who might be considered the chief foes of their race were the heads of the house of Athole. An uncontrolled, vehement spirit of revenge against that family burned in the breast of Rob Roy Macgregor; nor did he lose any opportunity of proving the sincerity of his professions of hatred.

Hitherto the wild feats of the marauder had met with continual success; no reverse had lessened his control over his followers, nor lowered his individual pride. But at length his enemy, the Earl of Athole, had a brief, but signal triumph over the dreaded chief. The circumstances under which it occurred are the following:—

Emboldened by his continued success, Rob Roy had descended into the plains, and headed an enterprise which was attended with the direst consequences: so desolating were its effects, that it is known by the name of the "Herriship of Kilrane." The outrage was severely taken up by Government, and a reward was offered for the head of the freebooter. It was even resolved to explore his cave. One day, when on the banks of Lochearn, attended by two of his followers, Rob Roy encountered seven men, who required him to surrender; but the freebooter darted from their view, and climbed a neighbouring hill, whence he shot three of the troopers, and dispersed the rest. This occurrence drove him, for some time, from his stronghold on Loch Lomond.
