Nashville Union order of battle

The following Union Army units and commanders fought in the Battle of Nashville of the American Civil War. Order of battle compiled from the army organization during the battle (December 15–16, 1864). The Union force was a conglomerate of units from several different departments provisionally attached to George H. Thomas’ Department of the Cumberland. The IV Corps and the District of Etowah were permanently attached to the Department of the Cumberland while the Cavalry Corps had been attached to the Army of the Cumberland until October 1864 when it was transferred to the Military Division of the Mississippi. The XXIII Corps was detached from the Department of the Ohio and Smith’s Corps (formerly known as the "Right Wing-XVI Corps") was detached from the Department of the Tennessee. Other brigades and regiments from the Army of the Tennessee which were unable to rejoin their respective commands were organized into the Provisional Division and attached to the District of the Etowah.
