This conduct, though natural, considering the country and time, was studiously represented at the capital as arising from an untameable and innate ferocity, which nothing, it was said, could remedy, save cutting off the tribe of MacGregor root and branch.
In an act of Privy Council at Stirling, 22d September 1563, in the reign of Queen Mary, commission is granted to the most powerful nobles, and chiefs of the clans, to pursue the clan Gregor with fire and sword.

A similar warrant in 1563, not only grants the like powers to Sir John Campbell of Glenorchy, the descendant of Duncan with the Cowl, but discharges the lieges to receive or assist any of the clan Gregor, or afford them, under any colour whatever, meat, drink, or clothes.
An atrocity which the clan Gregor committed in 1589, by the murder of John Drummond of Drummond-ernoch, a forester of the royal forest of Glenartney, is elsewhere given, with all its horrid circumstances.

The clan swore upon the severed head of the murdered man, that they would make common cause in avowing the deed.

This led to an act of the Privy Council, directing another crusade against the "wicked clan Gregor, so long continuing in blood, slaughter, theft, and robbery," in which letters of fire and sword are denounced against them for the space of three years.

The reader will find this particular fact illustrated in the Introduction to the Legend of Montrose in the present edition of these Novels.
Other occasions frequently occurred, in which the MacGregors testified contempt for the laws, from which they had often experienced severity, but never protection.
