[3] Between 16 and 26 April 1809, Rover captured four Danish sloops and their cargoes: Einigkeit, Fier Broders, Die Hoffnung, and Delphinen.
Nott threatened to fire on Reykjavík and Trampe agreed to a convention permitting British vessels to trade with Iceland unmolested.
With the help of other crew members, Jørgensen arrested Trampe and proclaimed himself 'Protector', promising that he would reinstate the Althing as soon as the Icelandic people were able to govern themselves.
His intent was to establish a liberal society in the spirit of those emerging in the Americas and Europe at the time; in practice he "imbibed all the quixotism of a petit Napoleon".
[12] When Talbot and Jørgensen arrived back in London, the Transport Board tried him and found him guilty of breaking his parole while a prisoner-of-war.
[13] In September, Lloyd's List reported that Rover had captured five or six Danish vessels, with one, the Aurora, of and from Christianstadt, arriving in Leith on the 16th, and another two days later.
[19] In March 1811 Rover accompanied the squadron under Admiral Joseph Sidney Yorke which was sailing to the Tagus carrying reinforcements for Arthur Wellesley's army, fighting in the Peninsular War.
[21] A later report was that a French squadron had captured Mary, Donaldson, master, which had been sailing from Alicant to Bristol, but had left her adrift.
She was under the command of M. Abraham Giscard and had left Batavia on 7 August 1811 with a cargo of spices, sugar, and coffee, the greater part of which belonged to the French government, and which she was taking to Rochelle.
[23] When news of the outbreak of the War of 1812 reached Britain, the Royal Navy seized all American vessels then in British ports.
Rover was among the 42 Royal Navy vessels then lying at Spithead or Portsmouth and so entitled to share in the grant for the American ships Belleville, Janus, Aeos, Ganges and Leonidas seized there on 31 July 1812.
[26] Lord Keith appointed Lieutenant Francis Erskine Loch (acting) commander of Rover in October 1812 and ordered him to patrol between Ushant and Île de Batz.
[27] Loch and Rover captured the American letter-of-marque schooner Experiment on 21 October off the Cordoban Light after a nine-hour chase.
[28][f] On 30 November, Rover captured the American brig Empress, of 275 tons (bm), and 12 men, which had been sailing from New York to Bordeaux with a cargo of cotton, coffee, and sugar.
During the night Iris captured the merchantman, which turned out to be the American letter-of-marque ship Union, M. Olmstead, master, which had been sailing from Philadelphia to Bordeaux with a valuable cargo of cotton.
[h] On 26 January 1813 Rover captured the American schooner Governor M'Kean, of 112 ton (bm), one gun, and 16 men, which had been sailing from Philadelphia to Bordeaux with a cargo of cotton and bees' wax.
[37] Earlier, operating as a 5-gun privateer with a crew of 65 men under the command of Captain Lucet, Governor M'Kean had captured two ships and a brig.
One of her prey had been the packet Prince Adolphus, under the command of Captain Boulderson, of eight guns and 36 men, which had been carrying the Lieutenant Governor of Demerara.
[38][39] Rover was in company with Belle Poule when they captured the American schooner Meteor, of 132 tons and 14 men, R. Bartlett, master, on 13 March 1813.
[40] Four days later, Rover captured the American schooner Independence, of 149 tons and 9 men which was sailing from La Rochelle to New York with a cargo of brandy.
Rover shared the proceeds of the capture with Superb and Pyramus,[43] and the hired armed cutter Fancy, which were in sight.
[49] Instead Commander Henry Montressor took up the position[1] Rover skirmished with American forces on the Potomac, and participated in the unsuccessful British attack on Baltimore between 12 and 15 September 1814.
In 1815 Rover accompanied Rear-Admiral George Burlton in Cornwallis, escorting the outward-bound East India trade.
Rover went south of the equator, touching Maranham, Brazil, before returning to Britain with a convoy of merchant vessels from Barbados.
The "Principal Officers and Commissioners of His Majesty's Navy" offered "Rover, 18 guns and 385 tons", "Lying at Plymouth" for sale on that day.
[1] In January 1819, the London Gazette reported that Parliament had voted a grant to all those who had served under the command of Lord Viscount Keith at various times between 1812 and 1814.
