Stuart embarked upon a military career in 1768, when he enlisted as an
ensign in the
37th Regiment of Foot. He purchased a
lieutenancy in the
7th Regiment of Foot (Royal Fusiliers) in 1770 and a
captaincy in the
35th Foot in 1773. In October of that year, he became a
major in the
43rd Regiment of Foot, and saw service in the
American War of Independence. In October 1777, he was commissioned as a
lieutenant-colonel of the
26th Regiment of Foot, which he commanded until 1779. before coming back to
London as a liaison to the ministry. A harsh critic of the Army's conduct, he was, however, highly favored by
Sir Henry Clinton, with whom he corresponded regularly. His two sons were born after his return from America. He was promoted to
colonel in 1782, but his criticisms and the disfavor of
George III towards his father prevented further military commands. He had been elected MP for
Bossiney in 1776, succeeding his elder brother
Lord Mount Stuart, who had been created
Baron Cardiff. Stuart continued an MP for the remainder of his life, except the years 1794–1796, but showed little interest in politics. However, his pride and violent temper led him to quarrel with
Lord Hood, commanding the Mediterranean Fleet, and with the civilian viceroy of Corsica,
Sir Gilbert Elliot, Bt. His partiality for
Pasquale Paoli against Elliot, and other conflicts, led Stuart to resign in February 1795. On 25 March 1795, he left the colonelcy of the 68th for that of the
26th Regiment of Foot, which he held for the remainder of his life.
Defence of Portugal He took command of a force sent to
Portugal in January 1797 to defend
Lisbon, and was notably successful in instilling discipline and spirit into the force, which was partly foreign in composition.
Capture of Menorca In 1798, he was sent to attack
Menorca (historically called "Minorca" by the British) with 3,000 men, an appointment heartily approved by
Lord St Vincent, who praised Stuart as an excellent general and inspiring leader of troops. Though unequipped with siege artillery, he successfully dissimulated and bluffed the Spaniards into surrendering the island without loss of life, an exploit for which he was made a
Knight of the Bath. From 15 November 1798 until 1800, he served as the British governor of the island. In March 1799, he responded to an appeal by Admiral Nelson (who, like St Vincent, thought him an excellent leader), and brought the
30th and
89th Regiments under
Colonel Blayney to
Palermo, from whence they were dispatched to secure
Messina against French invasion.
Later life In April 1800 he resigned as governor of Menorca and returned to England. He was then offered the post of
Commander-in-Chief, Ireland, but died at his home in
Richmond Park on 25 March 1801 before he could accept. An able general and administrator, Stuart's quarrelsome disposition and tendency toward insubordination blighted an otherwise promising military career. ==Personal life==
