Lord Sinclair, meantime, having heard of these factions, and being sincerely affected to the cause of the Stuarts, wrote to his son "a sharp letter about his behaviour," and a visit of explanation from the Master instantly followed. During his absence there was a revulsion of feeling among the Grumblers, and some contrition was expressed by them for the part that they had acted; but the fiend returned, and the malcontents quietly relapsed.[234] The news of James's certain arrival silenced, for a time, all complaints; but again they revived. Lord Mar seems to have had some misgiving of this, when he wrote, "Those that made a pretext of the King's not being landed, are now left inexcusable, and if those kind of folks now sit still and look any more on, they ought to be worse treated than our worse enemies." Yet it appears by a subsequent letter, that the grievances of which the General complained so bitterly, were not cured even by the presence of the Chevalier; that those who had made a pretext of his absence to complain and despond, desponded still, and that, in fact, the malady was so deep-seated as to be incurable. It may be urged, in vindication of the Master, who obviously aggravated the spirit of the Grumblers, that the event proved that his apprehensions were well founded. It was, indeed, natural for an experienced officer who had served under Marlborough, to view with dissatisfaction and suspicion the feeble and tardy movements of Lord Mar. Yet a hearty well-wisher to any cause would have abstained from infusing distrust into those counsels which, whether wise or foolish, were destined to guide the adherents of the party. A man of honour will enter, heart and soul, into what he undertakes, or not enter at all. The conduct of Sinclair was that of a mean, morose spirit; and it is but fair to conclude that his motives for adopting the name of Jacobite were either those of personal advancement, or arose out of an enforced compliance with the wishes of his father.
