A week after he had been received at the levee of King George, the Earl embarked at Gravesend in a collier, attended by two servants, and accompanied by General Hamilton and Captain Hay. They were all disguised, and escaping detection, arrived on the third day afterwards at Newcastle. It has been even said, that in order the better to conceal his rank, the Earl of Mar wrought for his passage.[72] From Newcastle Lord Mar proceeded northward in another vessel; and landing at Elie, in Fifeshire, went first to Crief, where he remained a few days. He then proceeded to Dupplin, in the county of Perth, the seat of his brother-in-law, the Earl of Kinnoul, and thence, on the eighteenth of August, crossing the river Perth, he proceeded to his own Castle of Kildrummie, in the Braes of Mar. He was accompanied by forty horse.

On the day after the arrival of the Earl at Kildrummie, he despatched letters to the principal Jacobites, inviting them to attend a grand hunting-match in Braemar on the twenty-seventh of August. This summons was couched in this form, for fear of a more explicit declaration being intercepted, revealing the design; but the great chiefs who were thus collected together were aware that "hunting" was but the watchword.

A gallant band of high-spirited chieftains answered the call. It is consolatory to turn to those who, unaffected by the intrigues of a Court, came heartily, and with a disinterested love, to the cause of which the Earl of Mar was the unworthy leader.

First in rank, was the Marquis of Huntly, eldest son of George, the first Duke of Gordon, and of that daring Duchess of Gordon, a daughter of the house of Howard, who, in 1711, had presented to the Dean and Faculty of Advocates in Edinburgh a silver medal, with the head of the Chevalier on one side, and on the other the British Islands, with the word "Reddite." The learned body to whom the Duchess had proposed this dangerous gift, at first hesitated to receive it: after a debate, however, among their members, it was agreed that the donation should be accepted, and a vote was passed to return thanks to the Duchess. The Advocates then waited in a body upon the Duchess, and expressed their hopes that her Grace would soon have occasion to present the Faculty with a second medal on the Restoration.[73] The Duke of Gordon, notwithstanding his having been brought up a Roman Catholic, was neutral in the troubles of the Rebellion of 1715, but his son took a force of three thousand men into the field,—the clan siding with the young Marquis rather than with their chief. The Marquis of Huntly was, probably for that reason, spared in the subsequent proceedings against the Jacobites, his participation in their schemes being punished only by a brief imprisonment.

William Marquis of Tullibardine, one of the most constant friends to the House of Stuart, the Earl of Nithisdale, and the Earl Marischal, also appeared at the time appointed. It was the fortune of the Marquis of Tullibardine, like that of the Marquis of Huntly, afterwards to appear in the field unsanctioned by his father, the Duke of Athol, who either was, or appeared to be, in favour of Government, whilst his son headed the clan to the number of six thousand. Lord Nairn, the younger brother of the Marquis, also joined in the undertaking. Of these distinguished Jacobites, separate lives will hereafter be given in this work: it therefore becomes unnecessary any further to expatiate upon them here. Of some, whose biography does not present features sufficiently marked to constitute a distinct narrative, some traits may here be given.

Charles Earl of Traquair, who hastened to Braemar, was one of those Scottish nobles who claimed kindred with royalty. He was descended from Sir James Stewart, commonly called the Black Knight of Lorn, and from Jane, daughter of John Earl of Somerset, and widow of King James the First. One of Lord Traquair's ancestors, the first Earl, had levied a regiment of horse, in order to release Charles the First from his imprisonment in the Isle of Wight; but, marching at the head of it at the battle of Preston, he and his son, Lord Seatoun, were taken prisoners and conveyed to Warwick Castle, where they languished four years in imprisonment, with the knowledge that their estates had been sequestered.

Connected with the family of Seatoun, on his mother's side, the Earl of Traquair had married the sister of Lord Nithisdale, being thus nearly related to two of those chiefs who gladly obeyed the summons of Lord Mar to the hunting-field. The Earl of Traquair appears to have escaped all the penalties which followed the Rebellion of 1715, perhaps because he does not appear to have taken any of his tenantry into the field.

Less prudent, or less fortunate, William Mackenzie, Earl of Seaforth, joined the standard of James Stuart with a body of three thousand men. He was attainted when the struggle was over, and his estates, both in Scotland and England, forfeited. He escaped to the Continent; but, in 1719, again landed with the Spaniards at Kintail; and was wounded at the battle of Glenshiels, but being carried off by his followers, again fled to the Continent, with the Marquis of Tullibardine and the Earl Marischal. Lord Seaforth was one of those to whom the royal mercy was shown. George the First reversed his attainder, and George the Second granted him arrears of the feu duties due to the Crown out of the forfeited estates. The title has been eventually restored.

James Livingstone, Earl of Linlithgow, was amongst the many who experienced less clemency than the Earl of Traquair. He had been chosen one of the sixteen representative peers of Scotland, on the death of the Duke of Hamilton; and enjoyed the possession of considerable family estates, which were eventually forfeited to the Crown. He led a band of three hundred clansmen to the field.
