Then while in command of the third-rate HMS Implacable in the Baltic Sea and attached to the Swedish Navy he took part in the capture the Russian ship Sewolod (Vsevolod) during the Napoleonic Wars.

Martin also sat in Parliament for 14 years and was an outspoken critic of government attempts to reduce the Navy budget which ultimately saw him dismissed in 1831 by his old friend King William IV.

Martin died in October 1854, at the early stages of the Crimean War, planning the Baltic Campaign and investigating the possibilities of using poison gas weapons.

[1] Promoted to rear-admiral on 1 August 1811,[3] Martin was despatched with a squadron to the Baltic Sea, with his flag in the third-rate HMS Aboukir, and assisted in the defence of Riga against the Grande Armée during the French invasion of Russia.

[2] He became Second-in-Command at Plymouth Command, with his flag in the third-rate HMS Prince Frederick in 1812 and visited the Duke of Wellington's headquarters in Spain to co-ordinate army and navy supply requirements and operations in 1813.

[5] In this role, Martin dominated naval strategy, reducing the fleet from the enormous size deployed against the French to a much more streamlined service geared toward protecting merchant trade and the British Empire.

[8] Martin's strong pro-Tory political views eventually caused his downfall, when he used his position in Parliament as member for Plymouth, for which he had been elected in July 1818,[9] to publicly criticise the new Whig government of Earl Grey in 1830.

[14] As the Crimean War approached he returned to service at Portsmouth planning the Baltic Campaign and investigating the possibilities of using poison gas weapons.
