HMS Demerara was originally a mercantile schooner named Anna, constructed prior to her acquisition by the British Royal Navy in 1804. Specific details about her dimensions and construction materials are not provided in the source, but as a schooner of that period, she would have featured a fore-and-aft rig with two or more masts, designed for speed and maneuverability. In 1804, the Royal Navy purchased her and appointed Lieutenant Thomas Dutton as her commander. Her early service included an engagement off Demerara on 14 July 1804, where she encountered the well-armed French privateer Grande Décidée. During this encounter, Demerara was outmatched; after an hour of combat involving small arms and a broadside, she suffered one man killed and nine wounded, leading Dutton to surrender her to the privateer. Grande Décidée was armed with 22 guns and crewed by 155 men. Later, in 1806, the vessel—then known as Demerara—was involved in a notable engagement with the French three-masted schooner privateer Hebe. During this fierce one-and-three-quarter-hour resistance, Shipley, a merchant vessel, was also engaged. Demerara was severely wounded in the fight, with casualties including the second captain and four men killed, and many wounded on both sides. The French privateer Hebe was ultimately successful in plundering Shipley’s cargo. The Royal Navy recaptured Shipley later that year with HMS Galatea. Following her recapture, the vessel was renamed Anna on 15 August 1806, after the engagement with Hebe and the commissioning of a new vessel bearing the name Demerara. She remained in service under the name Anna until she was broken up in 1809. The vessel’s history illustrates the dangers faced by small naval schooners during the Napoleonic Wars and highlights her role in the broader context of maritime privateering and naval warfare of the period.
