HMS Madagascar (1822) Wikipedia
HMS Madagascar was a 46-gun fifth-rate Seringapatam-class frigate, built at Bombay and launched on 15 November 1822.
The Bavarian Prince Otto who had been selected as the King of Greece was delivered by the Madagascar to his new capital Nafplion in 1833. In 1843, the Madagascar was assigned to suppress the slave trade, which was illegal in Britain. Operating of the west African coast, it successfully detained the Portuguese slave schooner Feliz (detained 1837), The Brazilian slave ships Ermelinda Segunda (detained 1842), Independencia (1843), Prudentia (1843) and Loteria (1843) and the Spanish slave brigantine Roberto (1842), along with 2 other vessels of which the nationalities were not recorded. In 1848, the ship was made a storeship first in Devonport and then at Rio de Janeiro after 1853. It was eventually sold in 1863.
