Certain offensive words spoken by Lord Mohun in the chambers of a Master in Chancery, and addressed to the Duke of Hamilton, brought a long-standing enmity into open hostility. On the part of Lord Mohun, General Macartney was sent to convey a challenge to the Duke, and the place of meeting, time, and other preliminaries were settled by Macartney and the Duke over a bottle of claret, at the Rose Tavern, in Covent Garden. The hour of eight on the following day was fixed for the encounter, and on the fatal morning the Duke drove to the lodgings of his friend, Colonel Hamilton, who acted as his second, in Charing Cross, and hurried him away. It was afterwards deposed, that on setting out, the Colonel, in his haste, forgot his sword; upon which the Duke stopped the carriage, and taking his keys from his pocket, desired his servant to go to a certain closet in his house, and to bring his mourning-sword, which was accordingly done. This was regarded as a fatal omen in those days, in which, as Addison describes, a belief in such indications existed. The Duke then drove on to that part of Hyde Park leading to Kensington, opposite the Lodge, and getting out, walked to and fro upon the grass between the two ponds. Lord Mohun, in the mean time, set out from Long Acre with his friend, General Macartney, who seems to have been a worthy second of the titled bravo. Lord Mohun having taken the precaution of ordering some burnt wine to be prepared for him upon his return from the rencounter, proceeded to the place of appointment, where the Duke awaited him. "I must ask your Lordship," said Lord Mohun, "one favour, which is, that these gentlemen may have nothing to do with our quarrel." "My Lord," answered the Duke, "I leave them to themselves." The parties then threw off their cloaks, and all engaged; the seconds, it appears, fighting with as much fury as their principals. The park-keepers coming up, found Colonel Hamilton and General Macartney struggling together; the General holding the Colonel's sword in his left hand, the Colonel pulling at the blade of the General's sword. One of the keepers went up to the principals; he found Lord Mohun in a position between sitting and lying, bending towards the Duke, who was on his knees, leaning almost across Lord Mohun, both holding each other's sword fast, both striving and struggling with the fury of remorseless hatred. This awful scene was soon closed for ever, as far as Mohun was concerned. He expired shortly afterwards, having received four wounds, each of which was likely to be mortal. The Duke was raised and supported by Colonel Hamilton and one of the keepers; but after walking about thirty yards, exclaimed that "he could walk no farther," sank down upon the grass, and expired. His lifeless remains, mangled with wounds which showed the relentless fury of the encounter, were conveyed to St. James's Square, the same morning, while the Duchess was still asleep.[51]
