In the confusion of an undecided field of battle, he enriched his followers by plundering the baggage and the dead on both sides.
The fine old satirical ballad on the battle of Sheriffmuir does not forget to stigmatise our hero's conduct on this memorable occasion-- Rob Roy he stood watch On a hill for to catch The booty for aught that I saw, man; For he ne'er advanced From the place where he stanced, Till nae mair was to do there at a', man.
Notwithstanding the sort of neutrality which Rob Roy had continued to observe during the progress of the Rebellion, he did not escape some of its penalties.

He was included in the act of attainder, and the house in Breadalbane, which was his place of retreat, was burned by General Lord Cadogan, when, after the conclusion of the insurrection, he marched through the Highlands to disarm and punish the offending clans.

But upon going to Inverary with about forty or fifty of his followers, Rob obtained favour, by an apparent surrender of their arms to Colonel Patrick Campbell of Finnah, who furnished them and their leader with protections under his hand.

Being thus in a great measure secured from the resentment of government, Rob Roy established his residence at Craig-Royston, near Loch Lomond, in the midst of his own kinsmen, and lost no time in resuming his private quarrel with the Duke of Montrose.
For this purpose he soon got on foot as many men, and well armed too, as he had yet commanded.

He never stirred without a body-guard of ten or twelve picked followers, and without much effort could increase them to fifty or sixty.
The Duke was not wanting in efforts to destroy this troublesome adversary.
