High Quality Content by WIKIPEDIA articles! Admiral of the Fleet Louis Alexander Mountbatten, 1st Marquess of Milford Haven, GCB, GCVO, KCMG, PC (24 May 1854 - 11 September 1921), formerly Prince Louis Alexander of Battenberg, was a German prince related to the British Royal Family. After a career in the United Kingdom's Royal Navy lasting over forty years, in 1912 he was appointed First Sea Lord, the senior uniformed officer in the British naval staff. He took steps to ready the British fleet for combat as World War I began, but his background as a German prince forced his retirement at the start of the war when anti-German feeling was running high. Queen Victoria and her son Edward VII, when Prince of Wales, occasionally intervened in his career-the Queen thought that there was "a belief that the Admiralty are afraid of promoting Officers who are Princes on account of the radical attacks of low papers and scurrilous ones". However, Louis welcomed battle assignments that provided opportunities for him to acquire the skills of war and to demonstrate to his superiors that he was serious about his naval career.
