Nelson was one of the most popular and romantic naval heroes of all history. He went to sea at an early age, but first made a name for himself at the Battle of St. Vincent, in 1797. From that time until his death at Trafalgar in 1805, he led the British navy in several daring and audacious sea-fights, including the Nile and Copenhagen. His victories gave Britain undisputed control of the seas at a time she was at great threat from an invasion by Napoleon.
