"I will recover my own dominions with my own subjects," was the boast of James, "or perish in the attempt." Unhappily, like his son, his magnanimity ended in expressions.

Sir John Maclean accompanied James when he landed, on the twelfth of March, 1689, in Ireland; after the siege of Derry, the chief returned to Scotland, accompanied by Sir Alexander Maclean of Otter, and there very soon showed his determination in favour of the insurrection raised by Dundee.

Sir John Maclean's first step was to send Maclean of Lochbuy as his lieutenant with three hundred men to join Dundee. His party encountered a major of General Mackay's army at Knockbreak in Badenoch; a conflict ensued, and Mackay's men were put to flight. This was the first blood that was shed for James the Second in Scotland.

Sir John Maclean soon afterwards joined Dundee in person, leaving his castle of Duart well defended. This fort, which had witnessed so many invasions, was besieged during the absence of the chief by Sir George Rooke, who cannonaded it several days without effect. Its owner, meantime, had joined Dundee, and was appointed to the command of the right wing of the army.

At the battle of Killicrankie, Sir John Maclean distinguished himself, as became the descendant of a brave and loyal race, at the head of his clan; he probably witnessed the death of Dundee. Few events in Scottish history could have affected those who followed a General to the field so severely. Lord Dundee had been foremost on foot during the action; he was foremost on horseback, when the enemy retreated, in the pursuit. He pressed on to the mouth of the Pass of Killicrankie to cut off the escape. In a short time he perceived that he had overrun his men: he stopped short: he waved his arm in the air to make them hasten their speed. Conspicuous in his person he was observed; a musket-ball was aimed at that extended arm; it struck him, and found entrance through an opening in his armour. The brave General was wounded in the arm-pit. He rode off the field, desiring that the mischance might not be disclosed, and fainting, dropped from his horse. As soon as he was revived, he desired to be raised, and looking towards the field of battle asked how things went. "Well," was the reply. "Then," he said, "I am well," and expired.

William the Third understood the merits of his brave opponent. An express was sent to Edinburgh with an account of the action. "Dundee," said the King (and the soldier spoke), "must be dead, or he would have been at Edinburgh before the express." When urged to send troops to Scotland, "It is needless," he answered; "the war ended with Dundee's life." And the observation was just: a peace was soon afterwards concluded.[83]

Sir John Maclean, nevertheless, continued in arms under the command of Colonel Cannon, and lost several brave officers by the incapacity of this commander. After the peace was signed, he returned to live upon his estates, until Argyle, having procured a commission from William to reduce the Macleans by fire or sword, invaded the island of Mull with two thousand five hundred men. Sir John being unprepared to resist him, after advising his vassals to accept protection from Argyle, again retired to the island of Thernburg, whence he captured several of King William's vessels which were going to supply the army in Ireland.[84]

The massacre of Glencoe operated in some respects favourably, after the tragedy had been completed, upon the circumstances of the Jacobites. Terrified at the odium incurred, a more lenient spirit was henceforth shown to them by Government. Many persons were exempted from taking the oaths, and were allowed to remain in their houses. Early in the year 1792, Sir John Maclean took advantage of this favourable turn of affairs, and, after obtaining permission through the influence of Argyle, and placing the castle of Duart under that nobleman's control, he went to England.

He soon became a favourite at the Court of one who, if we except the massacre of Glencoe, evinced few dispositions of cruelty to the Scottish Jacobites. King William is said, nevertheless, to have had a real antipathy to the Highlanders; and Queen Mary, whose heart turned to the adherents of her forefathers, was obliged to conceal her partiality for her Northern subjects. It had appeared, however, on several occasions, during the absence of her consort, and was now evinced in her good offices to the chief of the clan Maclean. That the chief was of a deportment to confirm the kind sentiments thus shown towards him, the character which has been given of him amply proves.

Sir John Maclean was, as the author of Sir Ewan Cameron's life relates, "the only person of his party that went to Court, which no doubt contributed much to his being so particularly observed by the Queen, who received him most graciously, honoured him frequently with her conversation, and said many kind and obliging things to him. Sir John on his part acquitted himself with so much politeness and address, that her Majesty soon began to esteem him. He took the proper occasions to inform her of the misfortunes of his family, and artfully insinuated that he and his predecessors had drawn them all upon themselves by the services they had rendered to her grandfather, father, and uncle. She answered, that the antiquity and merit of his family were no strangers to her ears; and that, though she had taken a resolution never to interpose betwixt her father's friends and the King her husband, yet, she would distinguish him so far as to recommend his services to his Majesty by a letter under her own hand; and that she doubted not but that it would have some influence, since it was the first favour of that nature which she had ever demanded."
