The Marquis of Tullibardine accompanied Charles in his progress until the Prince landed at Glenfinnin [sic], which is situated about twenty miles from Fort William, and forms the outlet from Moidart to Lochaber; here the standard of Charles Edward was unfurled. The scene in which this ill-omened ceremonial took place is a deep and narrow valley, in which the river Finnin runs between high and craggy mountains, which are inaccessible to every species of carriage, and only to be surmounted by travellers on foot. At each end of the vale is a lake of about twelve miles in length, and behind the stern mountains which enclose the glen, are salt-water lakes, one of them an arm of the sea. The river Finnin empties itself into the Lake of Glenshiel, at the extremity of the glen. On the eighteenth of August Prince Charles crossed this lake, slept at Glensiarick, and on the nineteenth proceeded to Glenfinnin.
When Charles landed in the glen, he gazed around anxiously for Cameron of Lochiel, the younger, whom he expected to have joined him. He looked for some time in vain; that faithful adherent was not then in sight, nor was the glen, as the Prince had expected, peopled by any of the clansmen whose gathering he had expected. A few poor people from the little knot of hovels, which was called the village, alone greeted the ill-starred adventurer. Disconcerted, Prince Charles entered one of the hovels, which are still standing, and waited there for about two hours. At the end of that time, the notes of the pibroch were heard, and presently, descending from the summit of a hill, appeared the Camerons, advancing in two lines, each of them three men deep. Between the lines walked the prisoners of war, who had been taken some days previously near Loch Lochiel [sic].
The Prince, exhilarated by the sight of six or seven hundred brave Highlanders, immediately gave orders for the standard to be unfurled.
The office of honour was entrusted to the Marquis of Tullibardine, on account of his high rank and importance to the cause. The spot chosen for the ceremony was a knoll in the centre of the vale. Upon this little eminence the Marquis stood, supported on either side by men, for his health was infirm, and what we should now call a premature old age was fast approaching. The banner which it was his lot to unfurl displayed no motto, nor was there inscribed upon it the coffin and the crown which the vulgar notion in England assigned to it. It was simply a large banner of red silk, with a white space in the middle. The Marquis held the staff until the Manifesto of the Chevalier and the Commission of Regency had been read. In a few hours the glen in which this solemnity had been performed, was filled not only with Highlanders, but with ladies and gentlemen to admire the spectacle.

The castle is the traditional seat of Clan MacDonald of Clanranald, a branch of Clan Donald. Castle Tioram was seized by Government forces around 1692 when Clan Chief Allan of Clanranald joined the Jacobite Court in France, despite having sworn allegiance to the British Crown. A small garrison was stationed in the castle until the Jacobite Uprising of 1715 when Allan recaptured and torched it, purportedly to keep it out of the hands of Hanoverian forces.
