HMS Implacable (1805)

In early 1808 Russia initiated the Finnish War in response to Sweden's refusal to bow to Russian pressure to join the anti-British alliance. Russia captured Finland and made it a Grand Duchy under the Russian Empire. The British decided to take counter-measures and in May sent a fleet, including Centaur, under Vice-Admiral Sir James Saumarez to the Baltic. Thus in March 1808 Implacable was in the Baltic, under the command of Captain Thomas Byam Martin.

On 9 July, the Russian fleet, under Admiral Peter Khanykov, came out from Kronstadt. The Swedes massed a fleet under Swedish Admiral Cederstrom, consisting of 11 line-of-battle ships and 5 frigates at Örö and Jungfrusund to oppose them. On 16 August, Saumarez then sent Centaur and Implacable to join the Swedish fleet. They chased two Russian frigates on 19 July and joined the Swedes the following day.

On 22 August, the Russian fleet, which consisted of nine ships of the line, five large frigates and six smaller ones, moved from Hanko and appeared off the Örö roads the next day. The Swedish ships from Jungfrusund had joined Rear-Admiral Nauckhoff and by the evening of 24 August the combined Anglo-Swedish force had made its preparations. Early the next day they sailed from Örö to meet the Russians.[7]

The Anglo-Swedish force discovered the Russians off Hango Udd but the Russians retreated as the Allied ships followed them. Centaur and Implacable exhibited superior sailing and slowly outdistanced their Swedish allies. At 5am on 26 August Implacable caught up with a Russian straggler, the 74-gun Vsevolod (also Sewolod), under Captain Rudnew (or Roodneff).[7]

Implacable and Vsevolod exchanged fire for about 20 minutes before Vsevolod ceased firing. Vsevolod hauled down her colours, but Hood recalled Implacable because the Russian fleet was approaching. During the fight Implacable lost six dead and 26 wounded; Vsevolod lost some 48 dead and 80 wounded.

The Russian frigate Poluks then towed Vsevolod towards Rager Vik (Ragerswik or Rogerswick),[8] but when Centaur started to chase them the frigate dropped her tow.[7] The Russians sent out boats to bring her in, in which endeavor they almost succeeded. They did succeed in putting 100 men aboard her as reinforcements and to replace her casualties.

However, just outside the port, Centaur was able to collide with Vsevolod. A party of seamen from Centaur then lashed her mizzen to the Russian bowsprit before Centaur opened fire. Vsevolod dropped her anchor and with both ships stuck in place, both sides attempted to board the other vessel. In the meantime, Implacable had come up and added her fire to the melee. After a battle of about half an hour, the Russian vessel struck again.[7]

Implacable hauled Centaur off. Their prize was so firmly aground that after taking out the prisoners and wounded men, Sir Samuel Hood, in Centaur, ordered Vsevolod to be burnt. The British removed their prisoners and then set fire to Vsevolod, which blew up some hours later. Centaur had lost three killed and 27 wounded. Vsevolod lost another 124 men killed and wounded in the battle with Centaur;[7] 56 Russians escaped by swimming ashore. In all, Vsevolod had lost 303 killed, wounded and missing.

The action with Vsevolod was the largest engagement during the Anglo-Russian War. In 1847 the Admiralty awarded the Naval General Service Medal with the clasps "Implacable 26 Augt. 1808" and "Centaur 26 Augt. 1808" to all surviving claimants from the action.

Vice-Admiral Saumarez with his entire squadron joined the Anglo-Swedish squadron the next day. They then blockaded Khanykov's squadron for some months. After the British and the Swedes abandoned the blockade, the Russian fleet was able to return to Kronstadt.[8]

By the summer of 1809 Martin and Implacable were back in the Baltic, and Admiral Saumarez sent her and Melpomene to sail east of Nargen Island. At the beginning of July 1809 she and Melpomene sailed into the Gulf of Narva, some 110 miles east of Tallinn. There they captured nine vessels laden with timber, spars and cordage, which were the property of the Russian Emperor.[9] Implacable, Melpomene and Prometheus deployed their boats to search all the creeks and inlets along the coast but found nothing more. The squadron then began a search of the Finnish coast, which yielded them three more cargo vessels.[9] More importantly, the British discovered that a convoy was sheltering under Percola Point with an escort of eight gunboats. Each Russian gun-boat mounted both a 32 and a 24-pounder gun, and had a crew of 46 men.[9] The British decided to send in a cutting out party to seize the convoy, and its protectors. In Martin's word, the intent was "to impress these Strangers with that Sense of Respect and Fear, which His Majesty's other Enemies are accustomed to show to the British Flag".[9]

At 9pm on 7 July, Implacable, Melpomene, Prometheus and Bellerophon assembled 17 boats, all under the command of Lieutenant Joseph Hawkey of Implacable.[9] The Russians expected the British attack and positioned their vessels between two rocks off Hango Head (Hangöudde). This meant that the British would have to come straight towards the gunboats' cannon rather than flanking them. The British came straight in, enduring the fire without firing back, until they reached the Russians, at which point they boarded the gunboats.[9]

Of the eight gunboats, the British captured six, among them gun boats Nos. 5, 10, 13, and 15.[10] They sank one gunboat and one escaped.[9] The British also captured all twelve of the ships and vessels the gunboats had been protecting, as well as a large armed ship, which they burnt.[9] These were laden with powder and provisions for the Russian army. British losses were heavy. Grapeshot killed Hawkey while he was boarding his second gunboat. Including Hawkey, Implacable lost six men killed and 17 wounded. In all, the British lost 17 men killed and 37 wounded. The Russians lost at least 65 men killed, and 127 taken prisoner, of whom 51 were wounded.[9] For this action, the Admiralty issued the clasp "7 July Boat Service 1809" to the Naval General Service Medal.

In January 1810, Captain George Cockburn took command of Implacable. She then sailed to Quiberon Bay with a small squadron that also included Disdainful, a brig and the schooner Nonpareil, all escorting the Baron de Kolli. His mission was to arrange the escape of Ferdinand VII of Spain, whom the French had imprisoned at the Chateau of Valençay. The mission failed when Ferdinand refused to have anything to do with the British, and Kolli was arrested.[11][Note 1] Implacable then returned to Spithead.

On 17 July Rear Admiral Sir Richard Keats arrived on Implacable to take charge of the British support of the Spanish in the Siege of Cádiz. Marshal Victor's French army had completely blockaded the Isla de León by land and were further fortifying the coast with works that supplemented the existing defences. Eleven or twelve British and Spanish line-of-battle ships anchored as close to shore as they could without grounding. The allied troops defending Leon consisted of 16,500 Spaniards, 4,000 British and Germans, and 1,400 Portuguese.[12]

In August the Allies attacked the French at Moguer, a town in the province of Huelva. Cockburn, sailing in the brig-sloop Jasper, directed the naval portion of the attack. General Lacey's Spanish troops and horses landed from the transports on 23 August about 22 miles south of the town. They then marched along the beach with 11 flat boats under Lieutenant Westphal of Implacable moving with them. The boats then ferried the troops across a large branch of the river, enabling the troops to reach Moguer next morning. The Spanish took the French somewhat by surprise and drove them out of the town. The French, numbering perhaps 1100 men, rallied and counter-attacked several times, but without success. The Spaniards followed them, but most of the French were cavalry and were able to withdraw towards Seville. Spanish casualties were slight.[13]

Milford arrived in Cadiz on 2 September and Rear Admiral Keats moved to her. On 6 September Implacable sailed from Cadiz to Havana as escort to two Spanish 3-deckers. From there she sailed to Vera Cruz, Mexico, to pick up specie. She returned to Cadiz on 18 February 1811 with 2,000,000 dollars on board.[Note 2][Note 3] Implacable then participated in the defense of the Isla de Leon. In August Captain I. R. Watson took command. By 1813 Implacable was back in Plymouth.
