The campaign being at an end in the Netherlands, the duke of Ormond returned to England, where the party disputes were become more violent than ever. The whigs affected to celebrate the anniversary of the late king’s birth-day, in London, with extraordinary rejoicings. Mobs were hired by both factions; and the whole city was filled with riot and uproar. A ridiculous scheme was contrived to frighten the lord-treasurer with some squibs in a band-box, which the ministers magnified into a conspiracy. The duke of Hamilton having been appointed ambassador-extraordinary to the court of France, the whigs were alarmed on the supposition that this nobleman favoured the pretender. Some dispute arising between the duke and lord Mohun, on the subject of a lawsuit, furnished a pretence for a quarrel. Mohun, who had been twice tried for murder, and was counted a mean tool, as well as the hector of the whig party, sent a message by general Macartney to the duke, challenging him to single combat. The principals met by appointment in Hyde Park, attended by Macartney and colonel Hamilton. They fought with such fury, that Mohun was killed upon the spot, and the duke expired before he could be conveyed to his own house. Macartney disappeared, and escaped in disguise to the continent. Colonel Hamilton declared upon oath before the privy-council, that when the principals engaged, he and Macartney followed their example; that Macartney was immediately disarmed; but the colonel seeing the duke fall upon his antagonist, threw away the swords, and ran to lift him up; that while he was employed in raising the duke, Macartney, having taken up one of the swords, stabbed his grace over Hamilton’s shoulder and retired immediately. A proclamation was issued, promising a reward of five hundred pounds to those who should apprehend or discover Macartney, and the duchess of Hamilton offered three hundred pounds for the same purpose. The tories exclaimed against this event as a party-duel; they treated Macartney as a cowardly assassin; and affirmed that the whigs had posted others of the same stamp all round Hyde Park, to murder the duke of Hamilton, in case he had triumphed over his antagonist, and escaped the treachery of Macartney. The whigs, on the other hand, affirmed that it was altogether a private quarrel; that Macartney was entirely innocent of the perfidy laid to his charge; that he afterwards submitted to a fair trial, at which colonel Hamilton prevaricated in giving his evidence, and was contradicted by the testimony of divers persons who saw the combat at a distance. The duke of Marlborough, hearing himself accused as the author of those party mischiefs, and seeing his enemies grow every day more and more implacable, thought proper to retire to the continent, where he was followed by his duchess. His friend Godolphin had died in September, with the general character of an able, cool, dispassionate minister, who had rendered himself necessary to four successive sovereigns, and managed the finances with equal skill and integrity. The duke of Shrewsbury was nominated ambassador to France in the room of the duke of Hamilton; the duke d’Aumont arrived at London in the same quality from the court of Versailles; and about the same time the queen granted an audience to the marquis de Monte-leone, whom Philip had appointed one of his plenipotentiaries at the congress.
