Personal history.
Early history.
John Pascoe Grenfell was born in Battersea, Surrey on 20 September 1800 to John Maugham Grenfell and his wife Sophia Turner. In 1811 he entered the service of the British East India Company, and in 1819 he joined the Chilean Navy under Lord Cochrane. He took part in most of the conflicts undertaken by Lord Cochrane during the War of Chilean Independence, and rose to the rank of lieutenant. On 5 November 1820 Grenfell took part in the cutting out of the frigate "Esmeralda" and the following year in the pursuit of the Venganza and Prueba, the last major Spanish warships in the South Pacific. In 1823, he followed Lord Cochrane to Brazil, to fight in the Brazilian War of Independence. In August 1823, Grenfell now a Commander in the small brig "Dom Miguel" sailed to Belem do Pará and using a similar tactic used by Lord Cochrane at Maranham, persuaded the Portuguese forces to surrender by making them think a larger fleet was in the offing. During the war with Argentina in 1826, he commanded the brig Caboclo as part of the squadron blockading Buenos Aires under (British) Commodore James Norton. On 29 July, while engaged in a ship-to-ship engagement with the Argentine commander, Admiral William Brown, he lost his right arm. He then returned to England to recuperate.
Later life.
In 1828 Grenfell returned to Brazil, and during 1835–36 he commanded as a Commodore a squadron of ships on the lakes of Rio Grande do Sul against 'Farrapos' rebels. He was successful in defeating his opponents and forcing the surrender of the insurgent forces. In 1841 he was promoted to rear-admiral and in 1846 was appointed Brazilian consul general in Liverpool. One of his principal tasks was to supervise the construction of the state-of-the-art steam frigate 'Dom Afonso', to the lines of HMS Fury. She was built by Thomas Royden And Co., of Liverpool with engines from Benjamin Hicks and Co., of Bolton. In 1848, when 'Dom Afonso' was undergoing steam trials on the Mersey with Grenfell, the diplomatic corps and members of the Brazilian and French Royal families on board, the frigate rescued 160 passengers from the America bound immigrant ship "Ocean Monarch" which had caught fire one day out from Liverpool. The Brazilian government was so pleased with the performance of 'Dom Afonso' that Grenfell was ordered to sign a contract for a second steam frigate called 'Amazonas'.
In 1851, when war broke out between Brazil and Argentine dictator Rosas, Grenfell was posted back to Brazil to take command of their naval forces in the River Plate. In December of that year at the Battle of Tonelero, with the 'Dom Afonso' as his flagship, he successfully forced the passage of the Paraná River carrying a Brazilian army which combined with local forces to defeat Rosas. A grateful Brazilian Government recommended that he be made a Viscount, but the Emperor refused as Grenfell was not a Brazilian but had retained his British citizenship. He was however promoted to vice-admiral and then finally admiral and returned to Liverpool to resume his role as consul-general. In 1861, he attended the funeral of Lord Cochrane in Westminster Abbey as the representative of the Brazilian Government. He died in Paris in 1869.
