to have been engaged in many and desperate feuds, one of which finally
proved fatal to himself and many of his followers. This was the
celebrated conflict at Glenfruin, near the southwestern extremity of Loch
Lomond, in the vicinity of which the MacGregors continued to exercise
much authority by the _coir a glaive,_ or right of the strongest, which
we have already mentioned.

There had been a long and bloody feud betwixt the MacGregors and the
Laird of Luss, head of the family of Colquhoun, a powerful race on the
lower part of Loch Lomond. The MacGregors' tradition affirms that the
quarrel began on a very trifling subject. Two of the MacGregors being
benighted, asked shelter in a house belonging to a dependant of the
Colquhouns, and were refused. They then retreated to an out-house, took a
wedder from the fold, killed it, and supped off the carcass, for which
(it is said) they offered payment to the proprietor. The Laird of Luss
seized on the offenders, and, by the summary process which feudal barons
had at their command, had them both condemned and executed. The
MacGregors verify this account of the feud by appealing to a proverb
current amongst them, execrating the hour _(Mult dhu an Carbail ghil)_
that the black wedder with the white tail was ever lambed. To avenge this
quarrel, the Laird of MacGregor assembled his clan, to the number of
three or four hundred men, and marched towards Luss from the banks of
Loch Long, by a pass called _Raid na Gael,_ or the Highlandman's Pass.

Sir Humphrey Colquhoun received early notice of this incursion, and
collected a strong force, more than twice the number of that of the
invaders. He had with him the gentlemen of the name of Buchanan, with the
Grahams, and other gentry of the Lennox, and a party of the citizens of
Dumbarton, under command of Tobias Smollett, a magistrate, or bailie, of
that town, and ancestor of the celebrated author.
