HMS Leander was a Portland-class 50-gun fourth rate of the Royal Navy, launched at Chatham on 1 July 1780. She served on the West Coast of Africa, West Indies, and the Halifax station. During the French Revolutionary Wars she participated in the Battle of the Nile before a French ship captured her. The Russians and Turks recaptured her and returned her to the Royal Navy in 1799. On 23 February 1805, while on the Halifax station, Leander captured the French frigate Ville de Milan and recaptured her prize, HMS Cleopatra. On 25 April 1805, cannon fire from Leander killed an American seaman while Leander was trying to search an American vessel off the US coast for contraband. The resulting "Leander affair" contributed to the worsening of relations between the United States and Great Britain. In 1813, the Admiralty converted Leander to a hospital ship under the name Hygeia. Hygeia was sold in 1817.
HMS Ajax was an Ajax-class 74-gun third-rate ship of the line of the British Royal Navy. She was built by John Randall & Co of Rotherhithe and launched on the Thames on 3 March 1798. Ajax participated in the Egyptian operation of 1801, the Battle of Cape Finisterre in 1805 and the Battle of Trafalgar, before she was lost to a disastrous fire in 1807 during the Dardanelles Operation.
HMS Britannia was a 100-gun first-rate ship of the line of the Royal Navy. The vessel was laid down in 1751 and launched in 1762. Nicknamed Old Ironsides, she served in the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars, including at the Battle of Trafalgar in 1805. One of the largest Royal Navy warships of her era, Britannia was one of only three British first-rates present at the battle, alongside HMS Victory and HMS Royal Sovereign. In 1806, the vessel was laid up and eventually converted into a hulk, before being broken up in 1825.
HMS Polyphemus, a 64-gun third-rate ship of the line of the Royal Navy, launched on 27 April 1782 at Sheerness. She participated in the 1801 Battle of Copenhagen, the Battle of Trafalgar, and the Siege of Santo Domingo. In 1813 she became a powder hulk and was broken up in 1827.
HMS Latona was a 36-gun, fifth-rate frigate of the Royal Navy that served during the American Revolutionary War, the French Revolutionary Wars, and the Napoleonic Wars. Shortly after her launch in 1781, she participated in the Battle of Dogger Bank against a Dutch squadron in the North Sea. In September 1782, Latona took part in the relief of Gibraltar and was the first ship in the convoy to pass through the Straits, when Richard Howe sent her ahead, to spy on the condition of the Franco-Spanish fleet in Algeciras Bay.
Vengeur ("Avenger") was a first-rate 118-gun ship of the line of the French Navy, of the Océan type, designed by Jacques-Noël Sané. She was the first ship in French service to sport 18-pounder long guns on her third deck, instead of the lighter 12-pounder long guns used before for this role.
HMS Powerful was a 74-gun third rate ship of the line of the Royal Navy. She took part in the defeat of a Dutch fleet in the Battle of Camperdown in 1797, the capture of a French privateer in the action of 9 July 1806, in operations against the Dutch in the East Indies during the raids on Batavia and Griessie in 1806 and 1807, and finally in the Walcheren Campaign during 1809.
HMS Centaur was a 74-gun third rate of the Royal Navy, launched on 14 March 1797 at Woolwich. She served as Sir Samuel Hood's flagship in the Leeward Islands and the Channel. During her 22-year career Centaur saw action in the Mediterranean, the Channel, the West Indies, and the Baltic, fighting the French, the Dutch, the Danes, and the Russians. She was broken up in 1819.
HMS Spencer was a 74-gun third-rate ship of the line of the Royal Navy, launched on 10 May 1800 at Bucklers Hard. Her designer was the French émigré shipwright Jean-Louis Barrallier. She served in two major battles, Algeciras Bay and San Domingo, and in a number of other campaigns. She was broken up in 1822.
Rear-Admiral Samuel Story was a Dutch naval officer. He commanded a Batavian Navy squadron which surrendered without a fight to the British Royal Navy during the Vlieter incident in 1799.
William Prowse CB was an officer of the Royal Navy, who saw service during the American War of Independence, and the French Revolutionary and Napoleonic Wars. Rising from humble origins and joining the navy as an able seaman, he had a highly active career, serving under some of the most famous naval commanders of the age of sail, and participating in some of their greatest victories. He was at Grenada and Martinique under Byron and Rodney, the Glorious First of June under Howe; and commanded ships at Cape St Vincent under Jervis, Cape Finisterre under Calder and Trafalgar under Nelson. He finished his career by serving with distinction in the Mediterranean, and died with the rank of Rear-Admiral.
The Atalante was a 40-gun Virginie-class frigate of the French Navy, launched in 1802.
The Dutch brig Komeet was launched in 1789 at Amsterdam. HMS Unicorn captured her on the Irish station in 1795. The British Royal Navy took her into service as HMS Comeet; it renamed her HMS Penguin in 1798. It sold her in 1808.
The Dutch sloop Sireene was launched in 1786. The British captured her in 1796 at the capitulation of Saldanha Bay. She then served in the Royal Navy, first briefly as the sixth rate HMS Daphne, and then from 1798 as the prison ship HMS Laurel. The Admiralty sold her in 1821.
Vrijheid was a Dutch 74-gun third rate ship of the line of the navy of the Dutch Republic, the Batavian Republic, and the Royal Navy. The order to construct the ship was given by the Admiralty of Amsterdam. The ship was commissioned in 1782.
Wassenaar was a Dutch 64-gun third rate ship of the line of the navy of the Dutch Republic and the Batavian Republic, and the Royal Navy. The order to construct the ship was given by the Admiralty of the Meuse. The ship was commissioned in 1781. In 1783/1784, the Wassenaar sailed to Batavia under Captain Gerardus Oorthuis.
Willem de Eerste was a 74-gun third rate ship of the line of the navy of the Dutch Republic, the Batavian Republic, and the Royal Netherlands Navy. The order to construct the ship was given by the Admiralty of the Meuse.
The capitulation of Saldanha Bay was the surrender to the British of a Batavian expeditionary force sent to recapture the Dutch Cape Colony in 1796. In 1795, early in the War of the First Coalition, French troops overran the Dutch Republic which then became a French client state, the Batavian Republic. Great Britain was concerned by the threat that the Cape Colony posed to its trade routes to British India. It therefore sent an expeditionary force that landed at Simon's Town in June 1795 and forced the surrender of the colony in a short campaign. British Vice-Admiral Sir George Elphinstone, then reinforced the garrison and stationed a naval squadron at the Cape Colony to protect it.
HMS Roebuck was a fifth-rate ship of the Royal Navy which served in the American and French Revolutionary Wars. Designed in 1769 by Sir Thomas Slade to operate in the shallower waters of North America, she joined Lord Howe's squadron towards the end of 1775 and took part in operations against New York the following year. She engaged the American gun batteries at Red Hook during the Battle of Long Island in August 1776, and forced a passage up the Hudson River in October. On 25 August 1777, Roebuck escorted troopships to Turkey Point, Maryland, where an army was landed for an assault on Philadelphia. She was again called upon to accompany troopships in December 1779, this time for an attack on Charleston. When the ships-of-the-line, which were too large to enter the harbour, were sent back to New York, Admiral Marriot Arbuthnot made Roebuck his flagship. She was, therefore, at the front of the attack, leading the British squadron across the shoal to engage Fort Moultrie and the American ships beyond.
