Sir John is, however, declared by another authority to have declined the commission thus offered to him. Although he had received King James's permission to reconcile himself with the Government, he did not, it appears, choose to bear arms in its defence. Such is the statement of one historian.[86] By another it is said that "Sir John was much caressed while he continued in the army,"[87]—a sentence which certainly seems to imply that he had assented to King William's offer. At all events, he managed to engage the confidence of the King so far, that William "not only honoured him with his countenance, but told Argyle that he must part with Sir John's estate, and that he himself would be the purchaser."

The nobleman to whom William addressed this injunction was of a very different temper from his father and grandfather, who had both died on the scaffold. Archibald, afterwards created by William Duke of Argyle, had in 1685 become the head of that powerful family; he was of a frank, noble, and generous disposition. "He loved," says the same writer, "his pleasures, affected magnificence, and valued money no further than as it contributed to support the expence which the gallantry of his temper daily put him to. He several times offered very easy terms to Sir John; and particularly he made one overture of quitting all his pretentions to that estate, on condition of submitting to be the Earl's vassall for the greatest part of it, and paying him two thousand pounds sterling, which he had then by him in ready money; but the expensive gayety of Sir John's temper made him unwilling to part with the money, and the name of a vassall suited as ill with his vanity, which occasioned that and several other proposals to be refused. However, as the generous Earl was noways uneasy to part with the estate, so he, with his usewall frankness, answered King William that his Majesty might always command him and his fortunes; and that he submitted his claim upon Sir John's estate, as he did everything else, to his royal pleasure."

A tradition exists in the family, that when Argyle sent messengers with his proposals to the Castle of Duart, Sir John pushed away the boat, as it neared the shore, with his own hands. This was worthy the pride of a Highland chieftain.

To such a height, in short, did William's favour amount, and so far did he in this instance carry his usual policy of conciliating his enemies by courtesy and aid, that he ordered Maclean to go as a volunteer in his service, assuring him that he would see that no harm was done to his property in his absence. Sir John, previous to his intended departure from England, went to Scotland to put his affairs in order. On his return he was told by Queen Mary that there were reports to his prejudice; he denied them, and satisfied the Queen that all suspicions of his fidelity were unfounded. Upon the strength of this assurance the Queen wrote in Maclean's favour to the King, in Holland, whither Sir John then proceeded to join his Majesty. But this profession of fidelity to one monarch soon proved to be hollow. Maclean was truly one of the politicians of the day, swayed by every turn of fortune, and cherishing a deep regard for his own interest in his heart. To inspire dislike and distrust wherever he desired to secure allegiance was the lot of William, of whom it has been bitterly said, that in return for having delivered three kingdoms from popery and slavery, he was, before having been a year on the throne, repaid "with faction in one of them, with rebellion in the other, and with both in the third." How expressive was the exclamation wrung from him, "that he wished he had never been King of Scotland." Sir John Maclean was one of those who added another proof to the King's conviction, "that the flame of party once raised, it was in vain to expect that truth, justice, or public interest could extinguish it."[88]

On arriving at Bruges, Maclean heard of the battle of Landau, in which the French army had proved victorious against the Confederates; and at the same time a report prevailed that a counter revolution had taken place in England, and that William was already dethroned. Sir John changed his course upon this intelligence, and hastened to St. Germains, where he was, as might be expected, coldly received. He remained there until the death of William, and then he married the daughter of Sir Enæas Macpherson of Skye.

Upon the accession of Anne, Sir John took advantage of the general indemnity offered to those who had gone abroad with James the Second, and resolved to avail himself of this opportunity of returning home; but, unluckily, he was detained until a day after the act had specified, by the confinement of his wife, who was taken ill at Paris, and there, in November 1703, gave birth to a son, who afterwards succeeded to the baronetcy. Although there was some risk in proceeding, yet Sir John, trusting to the Queen's favourable disposition to the Jacobites, embarked, and with his wife and child reached London. There he was immediately committed to the Tower, but his imprisonment had a deeper source than the mere delay of a few weeks. The Queensbury plot at that time agitated the public, and produced considerable embarrassment in the counsels of state.[89]

It appears that Sir John Maclean had taken no part in this obscure transaction which could affect his honour, or impair his chance of favour from Queen Anne; for, so soon as he was liberated, she bestowed upon him a pension of five hundred pounds a-year, which he enjoyed during the remainder of his life.

For some years Sir John Maclean continued to divide his time between London and the Highlands, where he frequently visited his firm friend Sir Ewan Cameron of Lochiel, at his Castle of Achnacarry. His estates had not been materially benefited by the brief sunshine of King William's favour. Upon finding that Maclean had gone to St. Germains, that monarch had confirmed to the Duke of Argyle the former grant of the island of Tyrie, which the successors of the Duke have since uninterruptedly enjoyed until the present day. Its value was, at the time of its passing into the hands of the Campbells, about three hundred pounds sterling per annum.[90] The chief of the clan Maclean was certain never to escape the suspicions of the Government, after the death of Anne, during whose reign the Highlanders experienced an unwonted degree of tranquillity. Upon her demise the whole state of affairs was changed; and none experienced greater inconveniences from the vigilance of Government than Sir Ewan Cameron and his friend Maclean. Lochiel, as his biographer observes, "drank deeply of this bitter cup."[91]

It was during one of Maclean's visits to Achnacarry, when in company with his now venerable friend, that the Governor of Fort William attempted to take him and Sir Ewan prisoners, but they made their escape. During the night of their flight, however, Sir Maclean caught a severe cold, which ended afterwards fatally.

When the Earl of Mar raised the standard of the Chevalier in Scotland, Sir John joined him at Achterarder, some days before the battle of Sherriff Muir. In that engagement the clan Maclean distinguished themselves, and some of their brave chieftains were killed in the battle. After the day was over, Sir John retired to Keith, where he parted from his followers, never to rejoin them. A consumption, incurred from the cold caught in his escape, was then far advanced. He declined an offer made to receive him on board the Chevalier's ship, bound for France, and went to Gordon Castle, where, on the twelfth of March, 1716, he expired.
