Lord Barrymore met with a sad fate on March 6, 1793, at the early age of twenty-four. He was an officer in the 2nd or Queen's Regiment, and, in pursuance of his duty, was escorting some French prisoners to Dover. He had kindly halted by the wayside, and treated everybody at an inn, when, on resuming the march, being tired, he got into his curricle, driven by his servant, he himself smoking a pipe of tobacco. A loaded gun which was placed between them, slipping down to the bottom of the carriage, by some mischance went off, and lodged its contents in his head, the charge entering at his cheek and coming out at the upper part of his skull. He was buried at Wargrave, and the Annual Register says of him: 'He died in a few minutes, and so finished a short, foolish, and dissipated life, which had passed very discreditably to his rank as a peer, and still more so as a member of society.'
He was succeeded in his title by his brother Henry (Cripplegate), who had neither the brains nor the bonhomie of Hellgate. He is thus described by Captain Gronow:[63]
'This nobleman came of a very old family, and, when of age, succeeded to a fine estate. He acquired no small degree of notoriety from his love of pugilism and cockfighting; but his forte lay in driving, and few coachmen on the northern road could "tool" a four-in-hand like him. His Lordship was one of the founders of the "Whip Club." The first time I ever saw Lord Barrymore was, one fine evening, while taking a stroll in Hyde Park. The weather was charming, and a great number of the bon-ton had assembled to witness the departure of the Four-in-hand Club. Conspicuous among all the "turn-outs" was that of his Lordship, who drove four splendid greys, unmatched in symmetry, action and power. Lord Barrymore was, like Lord Byron and Sir Walter Scott, club-footed. I discovered this defect, the moment he got off his box to arrange something wrong in the harness. If there had been a competitive examination, the prize of which would be given to the most proficient in slang and vulgar phraseology, it would have been safe to back his Lordship as the winner, against the most foul-mouthed of costermongers; for the way he blackguarded his servants, for the misadjustment of a strap, was horrifying. On returning home, I dressed, and went to the Club to dine, where I alluded to the choice morsels of English vernacular that had fallen from the noble whip's mouth, in addressing his servants, and was assured that such was his usual language when out of temper.
'In addition to his "drag" in the Four-in-hand Club, Lord Barrymore sported a very pretty "Stanhope," in which he used to drive about town, accompanied by a little boy, whom the world denominated his "tiger." It was reported that Lord Barrymore had, in his younger days, been taken much notice of by the Prince Regent; in fact, he had been the boon companion of his Royal Highness, and had assisted at the orgies that used to take place at Carlton House, where he was a constant visitor. Notwithstanding this, Lord Barrymore was considered by those intimately acquainted with him, to be a man of literary talents. He, certainly, was an accomplished musician, a patron of the drama, and a great friend of Cooke, Kean and the two Kembles; yet I have heard a host of crimes attributed to his Lordship. This, if not a libel, showed that the connection existing between the Prince Regent and this nobleman could not have been productive of good results, and tends to confirm the impression that the profligate life led by his Royal Highness, and those admitted to his intimacy, was such, as to make it a matter of wonder that such scandalous scenes of debauchery could be permitted in a country like ours. Indeed, his acquaintance with the Prince ruined Lord Barrymore both in mind, body and estate. While participating in the Regent's excesses, he had bound himself to do his bidding, however palpably iniquitous it might be; and, when he was discarded, in accordance with that Prince's habit of treating his favourites, he left Carlton House ruined in health and reputation.
'Lord Barrymore, during his last years, was a martyr to gout and other diseases: and, on his deathbed, he was haunted by the recollection of what he had been, and the thought of what he might have become: indeed, the last scene of his profligate life, when tortured by the inward reproaches of his accusing conscience, was harrowing in the extreme.'
