Back in service again with the outbreak of the American War of Independence, Inglis served in the Caribbean, where he captured a large Spanish privateer. He was in Sir Samuel Hood's fleet at the Battle of Saint Kitts in 1781, and, in 1782, fought at the Battle of the Saintes, where his old commander, now Admiral Sir George Rodney, defeated a French fleet. Inglis was given command of a small squadron of his own and cruised with some success during the last years of the war, capturing a French frigate. He retired ashore after the end of the war, was promoted to rear-admiral in 1790, and died the following year.
