There being a difficulty about engaging the people in a foreign war, Monk encouraged the Cavalier chiefs to raise troops for service as mercenaries abroad. But the King was shrewd enough to privately forbid it, and Monk had to fall back upon his other rules for the prevention of civil strife. The first was the perfection of the fortresses, the other the attainment so far as possible of uniformity of religion. The restrictions which Lilburne had placed upon the Presbyterians were gradually removed, and the Kirkmen encouraged at the expense of the sectaries. But while he gave them complete religious freedom, he was careful to strip the clergy of all temporal power by forbidding them the use of excommunication and by suspending the assemblies of the Kirk. From Dalkeith Monk governed the country in peace, attending to almost every detail himself. At first it is true that occasional plots disturbed his serenity, but his method of dealing with conspirators was as successful as it was original. It is, moreover, replete with a grim humour which gives us a new insight into his character. Such chiefs as fell under suspicion were arrested and placed under rigorous confinement. In noisome dungeons they were visited by Monk's roughest officers, and sometimes by the terrible general himself. There they were urged to confess, and even threatened with the torture. Those who yielded were at once released with a caution and never troubled again. Those who held out firmly were asked to dinner at Dalkeith, where the sound sense and excellent claret of their good-natured host soon brought them to reason. By this happy treatment the shrewd general found out at once whom he could safely ignore and who were dangerous. The first he knew he had frightened into good behaviour; of the others he made friends. Most notable of these was young Cameron of Lochiel, the Ulysses of the Highlands, the wolf-slayer, the man who had saved his life by tearing out the throat of one of Brayne's soldiers with his teeth. Evan Dhu was, in fact, the ideal hero of the clansmen, and though his action had been paralysed by the Inverlochy garrison, he had been the most dangerous and indefatigable figure in the late rising. He had been almost the last to come in, but from the day of his surrender the idol of the clans became Monk's devoted personal friend. These two men, so utterly different and yet in much so alike, seem to have conceived for each other an unbounded admiration. Monk gave the Prince of Robbers, as Charles the Second used to call him, a share in the administration of Lochaber, and supported him in his law-feuds, while at the crisis of Monk's career Lochiel attached himself to his staff and rode with him to London.
