On the one hand, the words of the dying man exculpated Mohun from any share in the actual murder; on the other hand, it is clear from the uncontradicted testimony of more than one witness, that he was fully cognizant of Hill's intentions, and that he did not hesitate to encourage him by his presence through the whole affair. According to the Attorney-General, his first question, when he surrendered himself, was, "Has Mr. Hill escaped?" and, upon being answered in the affirmative, he exclaimed, "I am glad of it! I should not care if I were hanged for him," his only regret being that Hill had escaped with very little money about him. He confessed, moreover, to the watch, that he had changed coats with his friend; the object, of course, was to throw out the pursuers as much as possible by this slight disguise.
This is Lord Mohun's portrait as drawn by a not unfavourable hand: "Charles, Lord Mohun, is the representative of a very ancient family, but he had the misfortune to come to the title young, while the estate was in decay; his quality introduced him into the best company, but his wants very often led him into bad; so that he became one of the arrantest rakes in town, and, indeed, a scandal to the peerage; was generally a sharer in all riots; and before he was twenty years old was tried twice for murder by the House of Peers. On his being acquitted at the last trial, he expressed his contrition for the scandal he brought upon his degree as peer by his behaviour, in very handsome terms, and promised to behave himself so, for the future, as not to give further scandal; and he has been as good as his word; for now he applies himself in good earnest to the knowledge of the constitution of his country, and to serve it; and having a good deal of fine and good sense, turned this way, makes him very considerable in the House. He is brave in his person, bold in his expressions, and rectifies, as fast as he can, the slips of his youth, by acts of honesty, which he now glories in more than he was formerly extravagant. He was married, when very young, to a niece of my Lord Macclesfield, who, dying without issue, left him a considerable estate,[18] which he well improves. The Queen continues him colonel of a regiment of foot. He is of middle stature, inclining to fat, not thirty years old."
