The circumstances of this tragic affair are recorded in Dean Swift’s “History of the Four Last Years of Queen Anne,” published in 1758, and are more fully detailed in “Transactions During the Reign of Queen Anne,” published in Edinburgh in 1790, by Charles Hamilton, a kinsman of one of the combatants. It appears that upon the return of Lord Bolingbroke, after the peace of Utrecht, and the suspension of hostilities between Great Britain and France, the Duke of Hamilton, long noted for his attachment to the Stuarts, and the acknowledged head of the Jacobite party, was appointed Ambassador Extraordinary and Plenipotentiary to the Court of France. Previous to his departure he wished to bring to a close the Chancery suit which had been pending between Lord Mohun and himself. With that view he, on the 13th November, 1712, attended at the chambers of Olebar, a Master in Chancery, where his adversary met him by appointment. In the course of the interview, Mr. Whitworth, formerly the steward of the Macclesfield family, gave evidence, and, as his memory was much impaired by age, the duke somewhat petulantly exclaimed, “There is no truth or justice in him,” upon which Lord Mohun retorted, “I know Mr. Whitworth. He is an honest man, and has as much truth as your grace.” This grating remark was allowed to pass unnoticed at the time, but Lord Mohun afterwards meeting with General Macartney and Colonel Churchill, both violent men, and declared partisans of the Duke of Marlborough, who had then been removed from the command of the army by the party to which the Duke of Hamilton was attached, it would seem that the offending person was induced by them to challenge the person offended. Preliminaries having been arranged, the combatants met in Kensington Gardens, Hyde Park, on the morning of the 15th November—the duke attended by his relative, Colonel Hamilton, and Lord Mohun by General Macartney. In a few moments the affair was ended, and when the park keepers, alarmed by the clashing of swords, rushed to the spot whence the sound proceeded, they found the two noblemen weltering in their blood—Lord Mohun was already dead, and the Duke of Hamilton expired before he could be removed. Nor had the combat been limited to the principals alone. The seconds had crossed swords and fought with desperate rancour. Colonel Hamilton remained upon the field, and was taken prisoner, but Macartney fled to the Continent. Colonel Hamilton subsequently declared upon oath, before the Privy Council, that, when they met upon the ground, the duke, turning to Macartney, said, “Sir, you are the cause of this, let the event be what it will.” To which Macartney replied, “My lord, I had a commission for it.” Lord Mohun then said, “These gentlemen shall have nothing to do here.” Whereupon Macartney exclaimed, “We will have our share.” To which the duke answered, “There is my friend—he will take his share in my dance.” Colonel Hamilton further deposed that when
