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 HMS Babet (1794) 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 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 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.
