XVI Corps (Union Army)

The XVI Army Corps was a corps of the Union Army during the American Civil War. The corps rarely fought as one unified unit, as its divisions were often scattered across the country.

The XVI Corps was organized on December 18, 1862 with Maj. Gen. Stephen A. Hurlbut in command. It had four divisions commanded respectively by William Sooy Smith (1st Division), Grenville Dodge (2nd Division), Nathan Kimball (3rd Division) and Jacob G. Lauman (4th Division). These divisions were assigned to garrison duty in the vicinity of Memphis, LaGrange and Corinth. With the Army of the Tennessee besieging Vicksburg, Maj. Gen. Ulysses S. Grant gathered reinforcements from the surrounding areas. The divisions of Smith, Kimball and Lauman were ordered to Vicksburg on June 12. This detachment was led by Maj. Gen. Cadwallader C. Washburn. Hurlbut and Dodge remained on garrison duty in Tennessee during this time. After the fall of Vicksburg, Smith's division was attached to the IX Corps and Lauman's division was attached to the XIII Corps during Maj. Gen. William T. Sherman's expedition to Jackson, Mississippi.

In 1864, the corps was divided into two wings of two divisions each.

The Left Wing was led by Maj. Gen. Grenville Dodge and participated in Maj. Gen. William T. Sherman's Atlanta Campaign. The left wing was composed of the divisions of Brig. Gen. Thomas W. Sweeny (2nd Division) and Brig. Gen. James C. Veatch (4th Division). These divisions fought notably at the Battle of Atlanta on July 22, 1864 holding off Confederate General John Bell Hood's flank attack. At this battle Veatch's division was led by Brig. Gen. John W. Fuller.
