It was to enforce the demand of this that he availed himself of Buckingham's sacrifice of the Treasurer, Cranfield, to the resentment of the Commons. "The greater the delinquent," he urged, "the greater the delict. They are a happy thing, great men and officers, if they be good, and one of the greatest blessings of the land: but power converted into evil is the greatest curse that can befall it." But the Parliament of 1626 had hardly met when Eliot came to the front to threaten a greater criminal than Cranfield. So menacing were his words, as he called for an enquiry into the failure before Cadiz, that Charles himself stooped to answer threat with threat. "I see," he wrote to the House, "you especially aim at the Duke of Buckingham. I must let you know that I will not allow any of my servants to be questioned among you, much less such as are of eminent place and near to me." A more direct attack on a right already acknowledged in the impeachment of Bacon and Cranfield could hardly be imagined, but Eliot refused to move from his constitutional ground. The king was by law irresponsible, he "could do no wrong." If the country therefore was to be saved from a pure despotism, it must be by enforcing the responsibility of the ministers who counselled and executed his acts. Eliot persisted in denouncing Buckingham's incompetence and corruption, and the Commons ordered the subsidy which the Crown had demanded to be brought in "when we shall have presented our grievances, and received his Majesty's answer thereto." Charles summoned them to Whitehall, and commanded them to cancel the condition. He would grant them "liberty of counsel, but not of control"; and he closed the interview with a significant threat. "Remember," he said, "that Parliaments are altogether in my power for their calling, sitting, and dissolution: and therefore, as I find the fruits of them to be good or evil, they are to continue or not to be." But the will of the Commons was as resolute as the will of the king. Buckingham's impeachment was voted and carried to the Lords. [Sidenote: Impeachment of Buckingham.]
