During the American Civil War, the fort was renewed as a US military post. In August 1861, the Union Army took command of Fort Scott, and readied it for the war times. The United States Army also took over several blocks within the town for commissary and quartermaster functions. The Union Army rented the properties from the current civilian owners. Troops from Indiana, Iowa, Colorado, Ohio, and Wisconsin would come to the fort, and either stayed by the fort, or traveled farther, to subjugate Missouri, Arkansas, or the Indian Territory. Fort Scott was one of the few installations that recruited and trained black soldiers for the United States Colored Troops of the Union Army.
