Born on 1 August 1811, son of Henry Stokes, of Scotchwell, near
Haverfordwest,
Pembrokeshire, and Anne, daughter of Dr George Phillips, Stokes joined the
Royal Navy on 20 September 1824. The first ship he served on was , and then in October 1825 he joined the crew of
Beagle under Captain
Phillip Parker King.
Beagle was involved in a survey of the waters of South America. In 1828 the commander of HMS
Beagle,
Pringle Stokes (not related to John Lort Stokes), committed suicide and
Robert FitzRoy assumed command; the ship returned to England in 1830 and was recommissioned. From 1831 to 1836 Stokes served under FitzRoy as assistant surveyor for the
second voyage of HMS Beagle, and shared his cabin with
Charles Darwin who was on board in a private capacity as a self-funded naturalist. Following this, Stokes was promoted to the rank of lieutenant, and served under Commander
John Clements Wickham for a survey of Australasian waters. When Wickham was invalided in 1841, Stokes took command of the ship. While Stokes was in command,
Beagle surveyed
Timor and
New Zealand, returning to England in 1843. When he returned he wrote an account of this voyage of the
Beagle, which was published in 1846 in two volumes. In July 1846 Stokes was promoted to captain and commanded the steamship surveying New Zealand for four years. This was one of 26
hydrography surveys conducted by the
British Hydrography Office around the world, and was also tasked with investigating natural resources and negotiating between British settlers and the
Māori inhabitants of New Zealand. Due to budget cuts,
Acheron was replaced by a smaller vessel, from 1851 to 1856. The charts produced by Stokes remain in use to this day. From 1860 to 1863 Stokes commanded the ship HMS
Rose, surveying the coasts of the
English Channel. He retired in 1863, was promoted to the rank of rear admiral in 1863, vice-admiral in 1871 and admiral in 1877. He died on 11 June 1885 at his home in Scotchwell. ==Legacy==
