"He was censured," observes this excellent writer, "by his enemies as being too tender of a family seat.[188] As I do not know the situation of this Castle, I cannot determine whether it was in his power to blow it up, or whether he had time to do it after he was informed of the march of the Hessians. But he has been so calumniated by the Secretary and his creatures, that nothing less than a direct proof ought to have any weight against him. In this case it is absurd to suspect him, because the family seat could never be in danger. If it was in his power to blow it up, he had only to acquaint the Governor when the mine was ready, and let him send one of his officers to view it; the Governor would certainly have prevented the effecting it and saved the Castle." "About the same time that the siege of Blair was abandoned, that of Fort William was also raised. It was found, indeed, difficult to make the Highlanders perform the regular duties of a siege; extremely brave in an attack, when allowed to fight in their own way, they were not possessed of that steady valour which is necessary to maintain a post; and it was not easy to keep them long in their quarters, or even at their posts, without action."[189] The loss of Blair, and the failure of the siege of Fort William, were followed by other misfortunes. Fatal mistakes in the vain endeavour to retrieve a sinking cause ensued. In the midst of his adversity, the young and gallant adventurer, for whom so much blood was shed, supported his spirits in a wonderful manner, and acted, with a heavy heart, the part of the gay and prosperous. He gave balls at Inverness, and even danced himself, which he had declined doing when in the midst of his prosperity at Edinburgh. Those who looked only on the surface of affairs were deceived by his appearance of happiness; but the well informed knew too well that the crisis which was to end the struggle was rapidly approaching. To complete the sad summary of disappointments and misfortunes, it was now ascertained that the expedition from Boulogne, and that from Dunkirk, with which the false-hearted French had so long amused the unfortunate Jacobites, were entirely and perfidiously relinquished. Lord George Murray, meantime, was ordered to march to Inverness. He was now worn with fatigues, and by the protracted anxieties of his situation. Foreseeing, as he must have done, many of the dangers and difficulties of the contest; observing, on the one hand, his eldest brother, the Marquis of Tullibardine, the adherent of the Stuarts, proscribed, impoverished, a nominal proprietor of his patrimonial estates; on the other, beholding his second brother, the actual Duke of Atholl, cherished by Government, prosperous, honours showered down upon him; what impulses less strong than that of a generous, and fixed principle of fidelity could have maintained his exertions in a service so desperate as that in which he had engaged?
