Leveson-Gower then commanded the 64-gun HMS Africa, sailing her to Guinea and the West Indies in 1765. Later he commanded the frigates HMS Aeolus and HMS Pearl, and finally the guardshipHMS Albion at Plymouth in 1774. He was appointed to command the 74-gun HMS Valiant in the English Channel in 1775, where he captured several American ships. He was present at the Battle of Ushant on 17 July 1778, where he strongly supported Admiral Augustus Keppel, Valiant sustaining casualties of six killed and twenty-six wounded. He gave evidence at Keppel's subsequent court-martial, defending his admiral's actions, and resigned his command afterwards.[1]
On 24 September 1787 he was advanced to be rear-admiral,[6] and in the following summer hoisted his flag again in Edgar in the Channel.[1] In 1788 he took an enlarged squadron to the West Indies. During the Spanish armament in 1790 he was again first captain to Lord Howe,[1] and in 1791 was selected as one of the rear-admirals to serve under Admiral Lord Hood in the fleet assembling to counter Russian aggression. The threat passed, however, and the fleet was disbanded.[7]
Death and issue
He died of a stroke while shaving on 15 August 1792 at his house at Bill Hill, Wokingham, and was buried on 23 August at Barkham parish church, Berkshire. He had married Frances Boscawen, eldest daughter of Admiral the Hon. Edward Boscawen and Frances Evelyn Glanville on 5 July 1773.[8] They had several sons, including John, who became a general and MP, Edward, who became a rear-admiral, and Augustus, who was a captain and drowned aged 21.[1] The small town of North Gower, in Ontario, Canada is named after him.[9]
