A three-quarter-length portrait to right, wearing a blue velvet coat lined with red silk, blue breeches and a red waistcoat laced with gold. His dress wig is white and he reclines against a gun barrel gesturing to the right with his left hand. He lost his right hand when a midshipman in an engagement with a French ship in 1697. The artist has indicated the loss of his hand by the positioning of the stump of his forearm in a pocket. In the right background a ship is shown in action. The fifth son of Lord Mountjoy, Stewart commanded a squadron against the Barbary pirates in 1720. He became Commander-in-Chief in the West Indies from 1729 to 1731, and second-in-command of the fleet under Sir John Norris in 1734. He became Vice-Admiral of the White in 1735 and Member of Parliament for Portsmouth from 1736 until his death.
