The Earl of Morton had no sooner assumed the reins of government, than his vigorous talents began to be felt. The chief strength of Mary’s friends was in Edinburgh Castle, held for her by Kirkaldy of Grange. All the means at the Regent’s command proving insufficient to reduce this fortress, he obtained from England an army of 1500 men, commanded by Sir William Drury, and provided with artillery. The castle stood a siege of three weeks, and was then obliged to yield (May 29, 1573). With mean vindictiveness, Morton sent the gallant Kirkaldy to the gallows. Maitland of Lethington might have shared the same fate, if it had not been anticipated either by a natural death or suicide. The other chiefs of the queen’s party were spared. After this event, the friends of Mary could no longer make an appearance anywhere in her favour. The new government remained triumphant, and peace was restored to a bleeding and exhausted country. Morton was, on the whole, a serviceable, though not a just or clement ruler. It was his policy, arising from his love of money, to punish his adversaries rather by fines than bloodshed. All the persons of note who had befriended the queen, he caused to give security for their future behaviour. The smallest offence forfeited the pledge, and the cautioners were then mulcted without mercy. Under this ruling passion, he tampered with the coin, sold justice, and cheated the church of its revenues. It was supposed that he had concealed large treasures in his castle of Dalkeith; but we have no certain account of their ever being found, and probably the popular notions on the subject were exaggerated. Under Morton, a slight move was made towards the establishment of a kind of episcopacy in the church, though the persons he appointed to the sees were mere creatures who consented to be receivers of the revenues on his account. The general feeling of the people continued to be decidedly in favour of the simple presbyterian polity, and the Regent’s interference with the purity of that system was one cause of his loss of popularity, and of his subsequent ruin. While the recognised champion of the Protestant interest in Scotland, and, as such, the _protégé_ of Elizabeth, he disliked the presbyterian clergy. He not only refused to countenance by his presence any of their assemblies, but ‘threatened some of the most zealous with hanging, alleging that otherwise there could be no peace or order in the country.’[83] The noted efforts of King James to bring the church into a prelatic conformity with England, had in reality an exemplar in the doings of the Regent Morton.
