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]
