ナサニエル・バンクス
During the American Civil War, the Thirteenth Connecticut, part of Union General Nathaniel P. Banks' forces, occupied Washington. The city was then larger than the parish seat of Opelousas. In "The Civil War in Louisiana", historian John D. Winters described the city as "squalid and dirty . . . [with] filth, ugly buildings, and its large number of black inhabitants."
