Attached to certain regiments which were then lying at Fort William, there were a number of young volunteers, men of good family, who had a soldier's pay, if they wished it, and were considered as pupils in the art of war, "at liberty to retire if they chose, and eligible, being often persons of family, to fill the vacancies which war or disease occasioned among the subalterns."[252] This regiment was now about to occupy the garrisons, and on their way to the Tyendrum or Black Mount, the officers engaged in conversation, little dreading an assault in a country inhabited only by a few herdsmen, and considered by them as wholly subdued. But they were deceived in their sense of safety. Among the heath and bushes in a narrow pass, circumscribed, on the one side, by a steep mountain, and on the other by a small lake, which skirted the path, for road there was not, lay in ambush two hundred well-armed and light-footed Highlanders. The youths, or volunteers, were in the rear of the regiment; as they marched fearlessly through the deep solitude of this wild district, the Highlanders sprang forwards from their ambuscade; and before the young soldiers could recover their surprise or have recourse to their arms, eight or ten young men of family were seized on and hurried away. With these were mingled others, among these volunteers of less importance, who were carried away in the confusion by mistake.

On arriving at Dumbarton the mystery was explained. There the commander of the corps found a letter, stating that "certain chiefs of clans had no objection to King William's ruling in England, considering that nation as at liberty to choose its own rulers; but that they never could, consistently with what they had sworn on their arms, take an oath to any other sovereign while the family of St. Germains remained in existence. They were," the writers continued, "unwilling either to perjure themselves, or to hold their lands in daily fear, and subject to the petty instruments of power. They were willing to live peaceably under the present rule, but were resolved neither to violate the dictates of conscience, nor to have their possessions disturbed. In the meantime, to prevent encroachments upon their lands, and to prevent the necessity of rushing into hostilities with the Government, they had taken hostages to ensure their safety, and
