In this state matters remained for some time, when David applied to the Steward, as the only person capable of restoring peace to the country, and, at the same time, commissioned him to put down the rebellion. The latter, satisfied that his objects would be more effectually forwarded by steady opposition to the court than by avowedly taking part with the insurgents, accepted the commission, and employed every means in his power to reduce the refractory barons to obedience. His efforts, however, were only partially successful. The Earls of Mar and Ross, and other northern barons, whose object was now attained, at once laid down their arms; John of Lorn and Gillespie Campbell likewise gave in their submission; but the Lord of the Isles, secure in the distance and inaccessible nature of his territories, refused to yield, and, in fact, set the royal power at defiance. The course of events, however, soon enabled David to bring this refractory subject to terms. Edward, finding that France required his undivided attention, was not in a condition to prosecute his ambitious projects against Scotland; a peace was accordingly concluded between the rival countries; and David thus found himself at liberty to turn his whole force against the Isles. With this view he commanded the attendance of the Steward and other barons of the realm, and resolved to proceed in person against the rebels. But the Steward, perceiving that the continuance of the rebellion might prove fatal to his party, prevailed with his son-in-law to meet the king at Inverness, where an agreement was entered into, by which the Lord of the Isles not only engaged to submit to the royal authority, and pay his share of all public burdens, but further promised to put down all others who should attempt to resist either; and, besides his own oath, he gave hostages to the king for the fulfilment of this obligation. The accession of Robert Steward or Stewart to the throne of Scotland, which took place in 1371, shortly after this act of submission, brought the Lord of the Isles into close connection with the court; and during the whole of this reign he remained in as perfect tranquillity, and gave as loyal support to the government as his father Angus had done under that of King Robert Bruce.[142] In those barbarous and unsettled times, the government was not always in a condition to reduce its refractory vassals by force; and, from the frequent changes and revolutions to which it was exposed, joined to its general weakness, the penalty of forfeiture was but little dreaded. Its true policy, therefore, was to endeavour to bind to its interests, by the ties of friendship and alliance, those turbulent chiefs whom it was always difficult and often impossible to reduce to obedience by the means commonly employed for that purpose.
