JOHN CAMPBELL entered the army in the reign of King George II., and was appointed Lieut.-Colonel of the 54th Regiment, now the 43rd Light Infantry, on the 25th of April, 1745, and served a short time on the Continent. The rebellion breaking out in Scotland in the same year, he quitted the Netherlands, and joined General Hawley with 1000 Argyleshire highlanders in January, 1746, on the day of the unfortunate battle of Falkirk. He subsequently joined the Duke of Cumberland at Perth, and accompanied his Royal Highness to the north. In November, 1755, he was promoted to the rank of Colonel, and appointed Aide-de-camp to the King. In the following month he obtained the Colonelcy of the 54th Regiment, then first embodied, from which he was removed in April, 1757, to the 14th Dragoons, and two years afterwards he was promoted to the rank of Major-General, and appointed Colonel of the Argyleshire Fencibles. In January, 1761, he was promoted to the rank of Lieut.-General. On the decease of his uncle, Archibald, third Duke of Argyle, in 1761, his father, General John Campbell, of the Scots Greys, succeeded to that title, and Lieut.-General Campbell of the 14th Dragoons obtained the designation of MARQUIS OF LORNE. In 1762 he was appointed Commander-in-Chief in Scotland, and in 1765 he obtained the Colonelcy of the ROYAL Regiment of Foot. He was again appointed Commander-in-Chief in Scotland in 1767, and in 1770 he succeeded to the title of DUKE OF ARGYLE. In March, 1778, he was promoted to the rank of General; four years afterwards he was removed from the ROYALS to the 3rd Foot Guards, and he was advanced to the rank of Field Marshal in 1796. The many virtues for which his Grace was distinguished occasioned him to be highly honoured and respected in society; and he died lamented on the 24th of May, 1806, in the 83rd year of his age. LORD ADAM GORDON, _Appointed 9th May, 1782_.
