The Battle of Mansfield, a Confederate victory under General Richard Taylor (son of Zachary Taylor), was fought here on April 8, 1864. This battle turned 42,000 Union troops away from their conquest of the Louisiana Confederate capital, Shreveport, and sent them in retreat to New Orleans. The battle is commemorated at the Mansfield State Historic Site some four miles south of Mansfield off Louisiana Highway 175.
The first woman's college west of the Mississippi River, Mansfield Female College, was founded by the Methodist Church there in 1855. A two-year college, its first class graduated in 1856. Financial difficulties and the threat of war closed the college from 1860 to the end of the American Civil War, during which its buildings served as a hospital for soldiers wounded in the battle of Mansfield; it reopened in 1865. In 1930, Mansfield Female College merged with Centenary College of Louisiana in Shreveport and closed its doors permanently. In 2003, the Louisiana State Legislature moved to convert the main building of Mansfield Female College, the Lyceum, into a future museum.
