Admiral Sir William Fanshawe Martin, 4th Baronet, GCB (5 December 1801 – 24 March 1895), was a Royal Navy officer. As a commander, he provided valuable support to British merchants at Callao in Peru in the early 1820s during the Peruvian War of Independence.[1] He became First Naval Lord in the Second Derby–Disraeli ministry in March 1858 and in that capacity acted as a strong advocate for the procurement of Britain's first ironclad warship. He went on to be Commander-in-Chief, Mediterranean Fleet and in that role provided important assistance during the Italian disturbances in 1860 and 1861, reformed the system of discipline in his fleet and developed a comprehensive system of manoeuvres for steam ships. ...
