This manuscript entitled "The 24th Corps" was likely written by General Edward O. C. Ord and his assistant Lieutenant Colonel Thomas G. Welles and accounts the troop movements of the 24th Corps of the Union Army during the American Civil War. The 24th Corps was formed in 1864 after the Army of the James separated white and Black troops into two units, the 24th and 25th Corps respectively, and the manuscript discusses this.
