Glamorgan was as zealous in his loyalty as in his speculative pursuits. He and his father had spent two hundred thousand pounds in the king's cause, and he was now engaged in an enterprise where he risked everything for Charles--name, honour, and life. He was furnished with a warrant which authorised him to concede the demands of the Catholics regarding their religion, and to engage them to send over ten thousand men. After many difficulties he reached Dublin, communicated to Ormond the plan, saw with him the Catholic deputies in Dublin, and then hastened to Kilkenny, to arrange with the council there. But at this time occurred the revelation of the scheme by the seizure of the Archbishop of Tuam's papers. The Parliament was thrown into a fury; the Marquis of Ormond, to make his loyalty appear, seized Glamorgan, and put him into prison, and the king sent a letter to the two Houses of Parliament, utterly disavowing the commission of Glamorgan, and denouncing the warrant in his name as a forgery. All this had been agreed upon before between the king and Glamorgan, should any discovery take place; and on searching for Glamorgan's papers a warrant was found, not sealed in the usual manner, and the papers altogether informal, so that the king might by this means be able to disavow them. But that Ormond and the council of Kilkenny had seen a real and formal warrant, there can be no question. The king, by a second letter to the two Houses, reiterated his disavowal of the whole affair, and assured them that he had ordered the privy council in Dublin to proceed against Glamorgan for his presumption. The proceedings were conducted by Lord Digby, who assumed a well-feigned indignation against Glamorgan, accusing him of high treason. The animus with which this accusation appeared to be made has induced many to believe that Digby was really incensed, because he had not been let wholly into the secret of Glamorgan's commission; and his letter to the king on the subject, noticed by Clarendon as rude and unmanly, would seem to confirm this. However, Glamorgan, on his part, took the whole matter very cheerfully, allowed the king's disclaimers without a remonstrance or evidence of vexation, and produced a copy of his secret treaty with the Catholics, in which he had inserted an article called a _defeasance_, by which the king was bound by the treaty no further than he pleased till he had seen what the Catholics did for him, and by which the Catholics were to keep this clause secret till the king had done all in his power to secure their claims.
