He was born in 1730, the youngest son of John Sawyer of Hayward, Berkshire by Anne, sister of Anthony Duncombe, Lord Feversham. He entered the navy in 1747, spending his first six years mostly on the Jamaica Station aboard George Townshend's HMS Gloucester.[1] He passed his lieutenant's examination on 30 August 1753, when his age was given as 'more than 22', suggesting he was born in or before 1730. He was promoted to lieutenant on 4 March 1756, and the following year was serving aboard HMS Grafton, which at the time was part of Vice-Admiral Francis Holburne's fleet off Louisbourg.[1]
Promotion to command
He received his first command, that of the sloopHMS Happy on 19 October 1758, but was soon moved to HMS Swallow off the coast of France under the orders of Lord Howe.[1] He took command of HMS Chesterfield on 26 December, followed with a transfer to HMS Active in February 1759. He spent the rest of the war aboard her. On 21 May 1762 he and the sloop HMS Favourite, the latter commanded by Philemon Pownoll, captured the Spanish treasure ship Hermione off Cadiz. A cargo of over £500,000 in cash and bullion was secured, of which Sawyer received £65,053 13s. 9d.[1] Now extremely wealthy, he married Susannah Ann Majendie, the daughter of a Lisbon merchant.[1] They had a daughter, Ann Sophia, who was the mother of Admiral Sir Henry Hope, K.C.B., and a son, Admiral Sir Herbert Sawyer, K.C.B., who inherited the Leicestershire estates of his father's cousin, the Hon. Frances Bowater, elder daughter and co-heir of Anthony Duncombe, Lord Feversham.
He left the Namur in 1785 and was appointed commodore of the North American Station's base at Halifax.[1] He took up his post in June, and authorized the frigate HMS Mercury to escort a merchant vessel to the American port of Boston to collect a shipment of cattle. This marked the first free visit of a British warship to the port since March 1776.[1] In 1787 Sawyer had taken part of his fleet to Quebec, where he was embarrassed by a French squadron of three ships of the line and four frigates, which sailed unchallenged along the Nova Scotia coast bound for Boston.[1] His daughter Sophia died in Halifax in 1788 and was buried in the crypt at St. Paul's Church (Halifax). Soon after he returned to England in August 1788.[1]
Further promotions
Sawyer never returned to sea but continued to rise through the ranks based on his seniority.[1] He was promoted to rear-admiral on 24 September 1788, vice-admiral on 1 February 1793 and admiral on 1 June 1795.[1] Poor health meant he was unable to take up any commands. He died in Bath, Somerset, on 4 June 1798.[1] His eldest son, also named Herbert Sawyer followed his father into a navy, and also had served in the American Revolution. He too reached the rank of admiral, and even was appointed to his father's old command on the North American Station, which he commanded during the War of 1812.[1]
