British naval hero, known for his flag signal “England expects that every man will do his duty.” Promoted rapidly after entering the navy at age 12, Nelson was given his first command in the French Revolutionary Wars. His destruction of the French fleet off of Aboukir in 1798 brought him fame and honors, and he was created Duke of Bronte by Ferdinand I of Naples. His scandalous affair with Lady Emma Hamilton met with official disapproval, but did not interfere with his defeat of the French and Spanish fleets at the decisive Battle of Trafalgar. This victory cost Nelson his life, but ensured British naval supremacy for one hundred years. ALS signed with his left-handed “Nelson & Bronte,” one page, 7.5 x 9, June 15, 1801. Letter to a Captain Brodie, informing him he has not received a promotion. In part, “It is with regret that I learn you are not amongst the fortunate.
