Samuel Pym
Sir Samuel Pym KCB (1778–1855) was a British admiral, brother of Sir William Pym. In June 1788, Pym joined the Royal Navy as captain's servant of the frigate "Eurydice". He was promoted to lieutenant of the sloop "Martin", under Captain William Grenville Lobb, and served under Lobb aboard the and the " Aimable". From November 1798, Pym served aboard the "Ethalion" (36), taking part in the capture of the Spanish "Thetis" and "Santa-Brigida" in 1799. The "Ethalion" was wrecked on the Penmarks on Christmas Day. From April 1804, Pym served aboard the "Mars", and from June on  the 74-gun "Atlas", under the overall command of Sir John Thomas Duckworth. Pym was decorated after the Battle of San Domingo, on 6 February 1806. In October 1808, Pym took command of the 36-gun frigate "Sirius", in the squadron of Commodore Rowley. In 1810, Pym was sent to the Isle de France (now Mauritius) to lead a squadron consisting of the frigates "Sirius", "Iphigenia", "Nereide", and the brig "Staunch". On 13 August, the squadron captured the Île de la Passe which commanded the entrance of Grand Port, and moved to blockade Port Louis. On 21 August, the squadron  seized the East Indiaman "Wyndham", previously captured by the French, and learnt that a French frigate squadron had arrived at Grand Port. The British squadron attempted to attack the French squadron at anchor and moved into the harbour. Entering it, the "Sirius" and "Magicienne" ran aground and became unmanoeuverable. The "Nereide" struck her colours before the French frigates, and the "Sirius" and "Magicienne" were scuttled by fire. The last ship of the squadron, the "Iphigenia", surrendered two days later. Pym, then at the Île de la Passe, was taken prisoner along with the whole garrison. The Battle of Grand Port  became the only defeat of a British squadron against Napoleonic France. Pym was released in December when Sir Albemarle Bertie recaptured the Île de la Passe. He was court-martialled and found innocent of the defeat. In February 1812, Pym was in command of the 74-gun ship "Hannibal", off Cherbourg, in May of the "Niemen", and in 1830 of HMS "Kent". Pym was made a rear-admiral in 1837. He served as admiral-superintendent at Devonport from 1841 to 1846, and in the autumn of 1845 commanded the experimental squadron in the Channel. He was promoted to vice-admiral  in 1847 and to full admiral in 1851.
