She was built to the design of the captured French frigate Melpomene (taken in 1794).
French Revolutionary Wars
Hydra was commissioned in April 1797 under Captain Sir Francis Laforey.
On 30 January 1804, Hydra and Tribune, operating independently, encountered a French flotilla of 20 vessels off Cape La Hogue, and captured three gun brigs and a lugger. The gun brigs were of 100 tons burthen and new, having been launched only ten days earlier and having been rigged while still in the stocks. They had troops aboard that had embarked the day after the launch. The vessels were from Saint-Malo, sailing to Cherbourg.
Hydra captured brig No. 51 and lugger no. 411. The brig was armed with three 24-pounder guns and was under the command of a lieutenant de vaisseau. She had 50 men aboard, a lieutenant and 26 of whom were from the 32nd Regiment of the Line. The lugger was armed with one 18-pounder, and had 36 men aboard. A lieutenant and 26 of whom were soldiers from the same regiment.
Fortune captured brigs No. 43 and No. 47. These brigs too had three guns each, mixed 18 (1) and 24-pounders (2). No. 43 had 50 men aboard and No. 47 had 60. The reports of the number of men captured are contradictory. Still, there both brigs were carrying troops from the same 32nd Regiment (or Demi-Brigade). Before capturing the two brigs, Tribune had destroyed a large boat. Bennett further reported that he had seen a frigate, which he believed was Hydra, capture a lugger and continue in pursuit of a brig. 
Hydra and Tribune shared the proceeds of the prize money and the head money for brigs Nos. 43, 47, and 51, and the lugger No. 411. However, because the two British vessels were there in different capacities, Hydra being part of a squadron under Admiral Sir James Saumarez, commander of Royal Navy forces in the Channel Islands, and Tribune reporting directly to Admiral George MontaguGeorge Montagu, Commander-in-Chief, Portsmouth, the division of the captains' shares of the prize money was complex.[Note 1]
After Admiral Lord Nelson defeated the French and Spanish fleets at the battle of Trafalgar on 21 October 1805, four French frigates and the brig Furet took refuge at Cadiz, where they remained into February 1806. To try to lure them out, Vice-Admiral Cuthbert Collingwood pulled his ships-of-the-line ten leagues out to sea, leaving only Hydra, under the Captain George Mundy, and the brig-sloop Moselle in close blockade. On 23 February a strong easterly wind drove the British off their station, which led the French commander, Captain Louis-Charles-Auguste Delamarre de Lamellerie, to seize the opportunity to escape. On the evening of 26 February Hydra and Moselle were three leagues west of the Cadiz lighthouse when they sighted the French vessels. Mundy began firing rockets and alarm guns to alert Collingwood, while sailing parallel to the escaping French squadron. Mundy then sent Carden in Moselle to try locate the British fleet. On the morning of 27 February Moselle reached Collingwood, who despatched three frigates to try to catch the French. In the meantime, Hydra had managed to isolate the French brig from her companions, and after a two-hour chase, captured the Furet. The French frigates did not come to their brig's aid, and after firing a pro forma broadside, Furet surrendered. Furet was armed with eighteen long 9-poundeer guns, and had a crew of 130 men under the command of lieutenant de vaisseau Demay. She was provisioned for a cruise of five months. Under the rules of prize-money, Moselle shared in the proceeds of the capture of Furet. During the next six months, Lamellerie's frigate squadron cruised the Atlantic, visiting Senegal, Cayenne and the West Indies, but failed significantly to disrupt British trade.
Hydra took part in the Peninsular War in 1807, including the bombardment of the defences of the Catalonian port of Bagur (Begu) on 7 August 1807. She was then out of commission for nearly three years.
During a refit at Portsmouth in 1813, she was fitted as a troopship and recommissioned in July 1813 under Captain Joseph Digby. From then until finally paying off in 1817 she was employed as a troopship and, in that capacity, for example, Captain Robert Lawson's Company, 8th Battalion Royal Artillery, left Spain on 22 July 1814, on board HMS Hydra, bound for Plymouth.
Hydra was sold in 1820.
Notes and citations
- The prize money arising out of this action was subject to an unusual split with respect to the two captains involved. Three-eights of the total prize money was allocated to the first-class shares, that is, the money that would go to Mundy and Captain R.H.A. Bennett of Tribune. One of the captains (and the prize money notice does not make clear which one), was subject to the rule requiring him to share one third of his share with his flag officer. The flag officer's share was therefore one-sixth of the amount for captains and flags, and amounted to £128 18s 11½d (16.7%). The captain who had to share received two-sixths, or £257 17s 11d (33.3%). The captain not subject to having to share with the flag officer received £386 16s 10½d (50%). A seaman received £1 4s.
