"The cannon," as Lord George Murray observes in his narrative, "were not only small, but bad. One of them seldom hit the Castle, though not half-musket shot from it."
Various schemes were formed by Lord George during this siege, but many obstacles concurred to check them. It had indeed been proposed before Lord George left Inverness, to blow up Blair Castle; but not only had Lord George no orders to attempt that, but there seemed also to be a difficulty from the situation of the place.
It appeared at one time his intention, also, to have set the building on fire. "On the eighteenth," writes Lord Elcho, "Lord George began to fire against the Castle with two four pounders; and as he had a furnace along with him, finding his bullets were too small to damage the walls, he endeavoured by firing red hot balls to set the house on fire, and several times set the roof on fire, but by the care of the besieged it was always extinguished. A constant fire of small arms was kept against the windows, and the besieged kept a close fire from the castle with their small arms." "As the castle," continues the same writer, "is situated upon rocky ground, there was no blowing it up; so the only chance Lord George had to get possession of it was to starve it, which he had some hopes of, as there were so many mouths in it." From this opinion, the judgment of Lord George Murray, in some measure, differed. "It might, I believe," he says, "have been entered by the old stables, under protection of which the wall could have been undermined, if I had been furnished with proper workmen." But all his efforts, in both these schemes, proved ineffectual. The red hot balls lodging in the solid timbers of the roof, only charred, and did not ignite the beams; and falling down, were caught up in iron ladles brought out of the Duke of Atholl's kitchen, and thrown into water. Disappointed in this attempt, Lord George removed his few field-pieces to a nearer position on the south side of the Castle, where, however, his firing produced no better effect than heretofore.
Never was there an officer more insensible to fear than the defender of Blair. Whilst Lord George was thus ineffectually battering the walls of the house, Sir Andrew Agnew looked out over the battlements; and seeing the little impression that was made on the walls, he exclaimed, "Hout! I daresay the man's mad, knocking down his own brother's house."
Meantime the siege lasted nearly a fortnight, and the garrison were reduced to the greatest extremity for provisions. One hope, however, the commandant had, and that was of sallying forth, and escaping. The Castle of Menzies was then occupied by Colonel Webster, who was posted there in order to secure the passage of the river Tay; and, as an alternative to starvation, a scheme was suggested for stealing out from Blair in the night time, and marching through a mountainous part of country to join the king's troops at Castle Menzies.
Whilst this project was in contemplation, the brave garrison were threatened with a new danger. During the blockade, there was heard a noise of knocking, seemingly beneath the floor of the Castle, as if miners were at work in its deep vaults, to blow it up. All the inmates of Blair thought such must indeed be the case: for Lord George had now gained possession of a bowling-green near the Castle, and also of a house in which the bowls were kept: from this bowl-house a subterranean passage might easily have been dug to the very centre of the ground underneath the building, and a chamber or mine formed there for holding barrels of gunpowder, sufficient to complete the work of destruction. This scheme must have occurred to the mind of Lord George Murray, who was born at Blair, and well acquainted with its construction. His objections to pursue it appear, as has been stated, to have been perceived and controverted by the Marquis of Tullibardine. They arose, as he has himself declared, and as the English also appear to have considered, from his want of workmen to perform the attempt. The plan of undermining was not thought practicable; and the noise which so greatly alarmed the garrison was proved to be only the reverberation of strokes of an axe with which a soldier was cutting a block of wood which lay on the floor of one of the uppermost rooms. The most unfavourable suspicions were, however, eventually affixed to Lord George's neglect of this mode of attack. Whether such conduct proceeded, on his part, from an aversion to destroy the home of his youth, and his birthplace; whether he had still hopes of reducing Sir Andrew to capitulate; or whether, as it has been often vaguely asserted, a secret agreement existed between himself and James, Duke of Atholl, that the Castle should be saved, can only be determined by a far closer insight into motives than human power can obtain. We may accord to Lord George Murray, without a blemish on his fidelity, a pardonable reluctance to level to the dust the pride of his family; that every effort was made to subdue Blair, except the last, is evident from the testimony of all contemporary historians.
Meantime the garrison had one source of confidence in their extremity, on which sailors are more apt to reckon than landsmen. They trusted to the luck of their commandant. Never had the stout veteran who had fought, in 1706, at Ramilies, been either sick, or wounded. He had never been in any battle that the English did not win. Yet it was deemed prudent not to allow any means of aid to be neglected, in so pressing a danger as the state of the siege presented.
The Earl of Crawford was then supposed to be at Dunkeld, having the command both of the British troops and of a body of Hessians who had lately been marched from Edinburgh. It was resolved to send to that nobleman for aid. The Duke of Atholl's gardener, a man named Wilson, undertook that dangerous embassy; he was charged with a letter from Sir Andrew to the Earl, and was allowed to take his choice of any horse in the Castle.[184]
Before Sir Andrew and his starving garrison could gain intelligence of the fate of Wilson, or could have heard the result of his enterprise, a strange reverse in their affairs took place. On the morning of the first of April, not a single Highlander was to be seen by any of the guards on duty. All had vanished; and a visit from the young woman from the inn at Blair shortly followed their disappearance. From her, the garrison heard that Lord George had, in fear of the arrival of troops from Dunkeld, suddenly withdrawn with all his followers. The old Sir Andrew, nevertheless, fearful of some stratagem, would not allow his garrison to sally out: they were shut up until the following day, when the Earl of Crawford appeared before the castle, and relieved all fears. The officers and soldiers were then drawn out, with Sir Andrew at the head of it. "My Lord," cried the old soldier, "I am very glad to see you; but, by all that's good, you are come too late, and we have nothing to give you to eat!" To which Lord Crawford answered courteously; and laughing, begged of Sir Andrew to partake of such provisions as he had brought with him. That day Sir Andrew and the Earl, and their officers, dined in the summer-house of the garden at Blair, in high spirits at the result of the siege.
The disappearance of Lord George Murray was soon explained; nor can the statement of those reasons which induced him to abandon the siege of Blair be given in a more satisfactory manner than as they were stated by Lord Elcho; to whom they must have appeared satisfactory, otherwise he would not have left so clear and decisive a testimony in favour of Lord George Murray's motives. It is worthy of remark, that Lord Elcho's statement agrees in every particular with that addressed some years afterwards by Lord George to Mr. Murray of Abercairney, and now preserved in the Jacobite Memoirs by Forbes.[185]
