Lieutenant-General George Macartney or MacCartney (c. 1660–1730) was an Irish-born professional soldier who went into exile to escape charges for his role in the 1712 Hamilton–Mohun duel.
[2] Macartney was intended to follow his father into the family business but volunteered for the army during the Nine Years War,[3] and served with much credit under the Duke of Marlborough and Prince Eugene.
[4] He was wounded and captured at the Battle of Almanza, where the regiment suffered heavy casualties; he was quickly exchanged and returned to the Low Countries in 1709, where he served as a volunteer at Malplaquet and subsequently made Major-general.
Hamilton accused McCartney of having stabbed the Duke while lying on the ground and he escaped to Hanover, where he remained until 1714, when he returned with George I.
[5] Soon after this, he demanded to be tried for the offence which had been laid to his charge, and on the evidence of the keepers of Hyde Park, who had witnessed the duel throughout all its phases, was honourably acquitted.
