About this time Rob Roy’s refuge appears to have been in the Breadalbane country. Now, at all events, he made up a feud with the Campbells, that had been chronic or intermittent in earlier days, when he ducked one laird of that name in the pool of Strath Fillan. His quarrel with Montrose drove him into a new alliance, and he is presently found attaching himself to the Duke of Argyll, for the sake of a clandestine protection extended to clients of the rival magnates. With the Campbell country to fall back on, he made guerrilla raids against the Grahams, by way of settling accounts which this unsuccessful cattle-dealer maintained to be in his favour. His mother is said to have been a Campbell, as also his wife, though another account makes her a Macgregor by birth, who may have passed under the Campbell name. That private war was interrupted by the rising of 1715. Rob would hardly have been a Macgregor had he not “gone out” at such a time; but most accounts of the campaign represent him as fighting or foraying too much for his own hand. He took the field as guardian of his young nephew, the chieftain of Glengyle, bynamed _Ghlune Dhu_, “Black Knee,” from a mole shown below his kilt; then to this scion of the house Rob seems to have set no chivalrous example. The battle of Sheriffmuir proved an indecisive one mainly through his refusing to lead the Macgregors to the charge; and his best part in the fight was plundering the baggage and the dead. He would not be the only Highlander in those wars who fought “not for King Shordy nor King Hamish, but for king _Spulzie_.” Balhaldie, head of another branch of the Macgregors, distinguished himself more at this battle fought close to his home. The attitude of “sitting on the fence” which Rob kept in this Jacobite rising, is thought to have been inspired by his connection with Argyll, the leader of the Hanoverian party in Scotland. But he was active enough on _creaghs_, pushed as far as Falkland Palace in Fife. His own country, at the outset, had been beaten up by the enemy. The Macgregors’ first act of war was to seize the boats on Loch Lomond. To recover them, a force of Dumbarton and Paisley volunteers with a band of Colquhoun Highlanders marched to Inversnaid, waked the mountain echoes with a great din of drumming and shooting, by which they boasted to have “cowed and frighted away” the Macgregors, whose captain, indeed, appears seldom forward to fight unless where something was to be got by it.
