At length Mar, who was kept back by the absence of the Pretender, determined to outwit Argyll by sending a detachment under Brigadier Mackintosh across the Firth of Forth below Stirling, whilst another body, under General Gordon, was despatched to seize on Inverary, and keep the clan Campbell in check. Mackintosh had about two thousand men under his command, chiefly from his own clans, but supported by the regiments of the Lords Nairn, Strathmore, and Charles Murray. To prevent these forces from crossing, three English ships of war ascended the Forth to near Burntisland; but whilst a detachment of five hundred men held the attention of the ships at that point, the main body were embarking on the right in small boats lower down, and the greater part of them got across the Firth, and landed at Aberlady and North Berwick. The city of Edinburgh was in consternation at this daring manœuvre, and at the proximity of such a force; and Mackintosh, hearing of this panic, and of the miserable state of defence there, determined to attempt to surprise it. He stayed one night at Haddington to rest his men, and on the 14th appeared at Jock's Lodge, within a mile of Edinburgh. But on the very first appearance of Mackintosh's troops, Sir George Warrender, the Provost of Edinburgh, had despatched a messenger to summon the Duke of Argyll from Stirling to the aid of the capital. The duke was already approaching Edinburgh, and therefore Mackintosh, perceiving that he had no chance of surprising the town, turned aside to Leith. Continuing southwards, Mackintosh joined the English insurgents at Kelso on the 22nd. This united force now amounted altogether to about two thousand men--one thousand four hundred foot commanded by Mackintosh, and six hundred horse under Lord Kenmure and Mr. Forster. This force might, in the paucity of troops in the service of the king, have produced a great effect had they marched unitedly southward and engaged General Carpenter, who was advancing from Newcastle, with only about nine hundred cavalry, to attack them; or had they gone at once north, taken Argyll in the rear, and then combined with Mar. But after marching to Jedburgh and then to Hawick, the Scots and English formed two different opinions. The Scots would not enter England, being persuaded by the Earl of Wintoun that, if they went into England, they would be all cut to pieces, or be sold for slaves. Mackintosh was willing to enter England, but they would listen to no one but Wintoun. Several hundred Highlanders deserted, and the remainder of the army, under the inefficient command of Forster, marched into England and reached Preston without molestation.
