First commissioned during the French Revolutionary Wars, Glenmore joined Admiral Adam Duncan's fleet in the North Sea, leaving for service in the English Channel in May 1797.In February 1800, Glenmore underwent a refit at Plymouth, during which the naval architect Robert Seppings introduced diagonal trusses that reduced hogging.The two frigates underwent design alterations common in fir-built ships, notably a flat, square tuck stern.[4] Work began in March when Glenmore's keel of 119 ft 6 in (36.42 m) was laid down at Woolwich Dockyard under the supervision of the master shipwright John Tovey.[1] The Amazon class of 1795 were originally intended as a series of four, but by the time the first one had been launched in 1795, Rule had already drawn up plans for HMS Naiad, an expanded version that was larger at 1,013 tons (bm), had a complement of 284 men and carried 38 guns.[6][1] Captain George Duff commissioned Glenmore in April 1796 for the North Sea and after joining Admiral Adam Duncan's fleet in July, spent several months harassing enemy shipping and escorting convoys to and from the Baltic.That evening, a portion of the crew broke into the small arms and powder lockers, threw the sergeant of marines overboard and posted guards throughout the ship.The following day, the mutineers requested that they be allowed to return to work, which was agreed, although they sent a boat to St Helens, Isle of Wight for further instructions from the delegates.[1][13] In December 1799 Glenmore and the sixth rate frigate HMS Aimable were escorting the West India convoy, comprising 40 to 50 vessels, from Cork.Amiable was sent to investigate and at 09:30 was close enough to make out three vessels; two French men-of-war and a larger ship with the uppermost sections of her masts removed.[15] Glenmore took possession of what turned out to be the East Indiaman Calcutta, which had been captured that same morning; René Lemarant de Kerdaniel was captain of the prize crew.[23] Glenmore sailed again on 10 June,[24] later capturing the French schooner Esperance and recapturing two British merchant vessels, William and Salem.[29] Duff transferred to the 74-gun third rate ship of the line HMS Courageaux in January 1801 and was replaced by Captain John Talbot.On approaching the Irish coast, a French privateer attacked and set on fire one of the convoy before being chased and captured by Glenmore[13] The Treaty of Amiens was ratified in March 1802, bringing the war to an end.[1] The "Principal Officers and Commissioners of His Majesty's Navy" offered "Glenmore, of 36 guns and 926 tons", lying at Plymouth, for sale on 3 November 1814.
