The cause of the Congregation now appeared to be triumphant, but it contained elements of weakness of which everyone was aware and which speedily became manifest. The acts of violence which had attended the revolt were filling the law-abiding citizens with dismay. The destruction of church property in Perth and St. Andrew's had been followed by similar excesses elsewhere. Especially disquieting had been what had occurred at Scone immediately after the surrender of Perth. In defiance of the protests of Knox, the lord James, and Argyle, the reformers of Dundee had sacked and burned to the ground the abbey and palace of that village--an outrage which Knox himself regretted in the interest of his own cause. It was a further source of weakness to the Congregation that their actions easily lent themselves to misconstruction and misrepresentation. The Regent industriously spread the plausible report both at home and abroad that their religious professions were a mere pretext, and that their real object was to overthrow herself and to make the lord James their king. But, above all, the nature of the host that supported them was such that it invariably failed them when their need was the greatest. The men who composed it had to leave their daily business in town and country; and, as they received no pay and their own affairs demanded their attention, their military service did not extend beyond a few weeks. The Protestant leaders had no sooner taken possession of Edinburgh than their following began to dwindle. During the first week their numbers amounted to over seven thousand men; by the third week they had diminished to one thousand five hundred. In these circumstances the Regent had only to bide her time, and her opportunity must come. On July 23d her troops, led by D'Oysel and Chatelherault, marched on Leith, which they reached on the morning of the 24th. As had been anticipated, neither that town nor the capital itself was in a position to offer any effectual resistance; and the leaders of the Congregation at once proposed a conference for the discussion of terms. Accordingly, the Duke and the Earl of Huntly on the one side, and Argyle, the lord James, and Glencairn on the other, met on the east slope of the Calton hill and agreed to the following adjustment: The Congregation were to give up the coining-irons, of which they had taken possession, and they were to evacuate Edinburgh within twenty-four hours. The town was to be left free to choose its own religion; no French troops were to be introduced. The Protestants were to be allowed complete liberty of worship, but were to abstain from violence against the old religion, and these arrangements were to hold till the 10th of the following January. By this concession of liberty to worship according to their own consciences the Protestants had apparently attained the main object for which they had risen, but they well knew that they would enjoy this liberty only so
