Being accused by Lord Rae, not without some appearance of probability, of a conspiracy against the king, Charles was so far from harboring suspicion against him, that, the very first time Hamilton came to court, he received him into his bed-chamber, and passed alone the night with him.[**] But such was the duke's unhappy fate or conduct, that he escaped not the imputation of treachery to his friend and sovereign; and though he at last sacrificed his life in the king's service, his integrity and sincerity have not been thought by historians entirely free from blemish. Perhaps (and this is the more probable opinion) the subtleties and refinements of his conduct, and his temporizing maxims, though accompanied with good intentions, have been the chief cause of a suspicion which has never yet been either fully proved or refuted. * It is not improper to take notice of a mistake committed by Clarendon, much to the disadvantage of this gallant nobleman; that he offered the king, when his majesty was in Scotland, to assassinate Argyle. All the time the king was in Scotland, Montrose was confined in prison. Rush. vol. vi. p. 980. ** Nalson, vol ii. p. 683. As much as the bold and vivid spirit of Montrose prompted him to enterprising measures, as much was the cautious temper of Hamilton inclined to such as were moderate and dilatory. While the former foretold that the Scottish Covenanters were secretly forming a union with the English parliament, and inculcated the necessity of preventing them by some vigorous undertaking, the latter still insisted, that every such attempt would precipitate them into measures to which otherwise they were not perhaps inclined. After the Scottish convention was summoned without the king's authority, the former exclaimed, that their intentions were now visible, and that if some unexpected blow were not struck to dissipate them, they would arm the whole nation against the king; the latter maintained the possibility of outvoting the disaffected party, and securing by peaceful means the allegiance of the kingdom.[*] Unhappily for the royal cause, Hamilton's representations met with more credit from the king and queen than those of Montrose; and the Covenanters were allowed, without interruption, to proceed in all their hostile measures. Montrose then hastened to Oxford where his invectives against Hamilton's treachery, concurring with the general prepossession, and supported by the unfortunate event of his counsels, were entertained with universal probation. Influenced by the clamor of his party, more than his own suspicions, Charles, as soon as Hamilton appeared, sent him prisoner to Pendennis Castle, in Cornwall. His brother Laneric, who was also put under confinement found means to make his escape, and to fly into Scotland.
