John Mostyn (British Army officer)

General John Mostyn (c.1709 – 16 February 1779) was a British soldier, MP and colonial administrator.
He was a younger son of Sir Roger Mostyn, 3rd Baronet and educated at Westminster School and Christ Church, Oxford.
He joined the army as an Ensign in 1733 and rose to the rank of General in 1772. He served as Groom of the Bedchamber to King George II from 1746 to his death.
Mostyn served as Governor of Minorca for a ten-year period between 1768 and 1778. It was a titular role and Mostyn was not in residence on the island, which meant that his deputy was in effective charge - from 1774 this was James Murray, his eventual successor who was forced to surrender the island in 1782 to a Spanish force.
He died unmarried.
