"On the twenty-fourth of March, the Hessians from Perth and Crieff moved to its relief. They encamped the first night at Nairn House, and next night at Dunkeld, and there was some firing betwixt them and a party of Lord George's across the river. Those that marched from Crieff encamped at Tay Bridge on the twenty-seventh. Upon this motion of the Hessians, Lord George sent an express to the Prince, to tell him that if he would send twelve hundred men, he would pitch upon an advantageous ground and fight them. The Prince sent him word he could not send him them in the way his army was then situated. On the thirty-first the Earl of Crawford marched with St. George's Dragoons, five hundred Hessians, and sixty Hussars, and encamped at Dawallie, four miles north of Dunkeld, and next day they advanced to Pittachrie. Both these days Lord George had several skirmishes with the hussars; but although he laid several snares for them, he never could catch but one of them, who was an officer and a Swede, who had his horse shot under him. Lord George used him very civilly, and sent him back with a letter of compliment which he wrote to the Prince of Hesse. On the first of April Lord George Murray drew his men up in battle opposite to Lord Crawford at Pittachrie, and then retreated before him, in order to draw him into the pass of Killicrankie; but Lord Crawford never moved, but sent for reinforcements to the Prince of Hesse. Lord George, upon hearing of the march of that reinforcement to sustain Lord Crawford, and that the body of Hessians from Lay Bridge were marching to Blair by Kinachin, quitted the country and marched his men to Strathspan, and from thence to Speyside. He himself went to Inverness, where he found his enemies had persuaded the Prince that he might have taken Blair Castle if he had had a mind, but that he had spared it because it was his brother's house; and in short they made the Prince believe, that in the letter he had wrote to the Prince of Hesse, he had engaged to betray him the first opportunity; and that by the Prince of Hesse and his brother's means, he was entirely reconciled to the government. What Mr. Murray had insinuated to the Prince about Lord George, on his first coming to Perth had made such an impression, that the Prince always believed it, notwithstanding Lord George's behaviour was such (especially in action) as to convince the whole army of the falsity of such accusations. However it opened his mind upon the matter of the Irish officers, so far as to make some of them promise to watch Lord George's motions, particularly in case of a battle, and they promised the Prince to shoot him, if they could find he intended to betray him."
