While working for the United States Coast Survey, he researched tides and currents, and located an uncharted shoal that had caused wrecks off of the coast of New York. During the American Civil War, he commanded the Western Gunboat Flotilla, where he won an important engagement in the First Battle of Memphis before capturing enemy supplies on a successful expedition up the Yazoo River. Davis was also one of the founders of the National Academy of Sciences in 1863 and he wrote several scientific books.
