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]

Lord Mohun, meanwhile, was carried, by order of General Macartney, to the hackney-coach in which he had arrived, and his body conveyed to his house in Marlborough Street, where, it was afterwards reported, that being flung upon the best bed, his Lady, one of the nieces of Charles Gerrard, Earl of Macclesfield, expressed great anger at the soiling of her new coverlid, on which the bleeding corpse was deposited.[52]

General Macartney escaped. It appeared on oath that he had made a thrust at the Duke, as he was struggling with Mohun; and it being generally believed that it was by that wound that the Duke died, an address was presented to her Majesty by the Scottish Peers, begging that she would write to all the kings and states in alliance with her, not to shelter Macartney from justice.[53]

A deep and general grief was shown for the death of the Duke of Hamilton. In Scotland mourning was worn, and the churches were hung with black. It was in vain that the Duchess offered a reward of three hundred pounds for the apprehension of Macartney; the murderer had fled beyond seas.

The Cavaliers lost, in Hamilton, an ornament to their party, from the strict honour and fidelity of his known character. But the crisis which the unfortunate Duke had in vain endeavoured to avert was now at hand, and the death of Queen Anne brought with it all those consequences which a long series of cabals, during the later disturbed years of the Queen's existence, had been gradually ripening into importance.

The Earl of Mar had openly espoused the High-church party in the case of Sacheverel; and he had on that account, as well as from the doubt generally entertained of his fidelity, little reason to expect from the House of Hanover a continuance in office. No sooner had the Queen expired, than those whom Lord Mar had long, in secret, been regarding with interest, expressed openly their disappointment at the result of the last reign.

"The accession of George the First," remarks Dr. Coxe, "was a new era in the history of that Government which was established at the Revolution. Under William and Anne the Stuart family can scarcely be considered as absolutely excluded from the throne; for all parties, except the extreme Whigs, looked forward to the possibility of the Stuarts returning to the throne. But, in fact, the Revolution was not completed till the actual establishment of the Brunswick line, which cut off all hopes of a return without a new revolution."[54]

When the news of Queen Anne's dangerous condition reached the Chevalier de St. George, he was at Luneville; but he repaired instantly to Barleduc, where he held a council. As he entered the council-chamber, he was heard to exclaim, "If that Princess dies, I am lost."[55] There was no doubt that a correspondence with the exiled family had been carried on with great alacrity, during the last few years of Queen Anne's reign, with the cognizance of the Sovereign;[56] and that large sums were spent by Mary of Modena, and by her son, in procuring intelligence of all that was going on in the English Court.
