Two hundred years ago, Napoleon Bonaparte dominated Europe and threatened Britain with invasion. Against him stood the Royal Navy and the already legendary Admiral Horatio Nelson. In October 1805, a massive naval battle off the coast of Spain decided mastery of the seas, and over the following days and nights, the battleships and their exhausted crews endured a gale of awesome fury. The authors tell this story through the diaries, letters, and memoirs of the men involved, as well as through the eyes of their wives and children.
