6th Tennessee Cavalry Regiment (Union)

The 6th Tennessee Cavalry Regiment was a cavalry regiment that served in the Union Army during the American Civil War. The regiment was also known as the 1st West Tennessee Cavalry; and was sometimes referred to as Hurst's Worst by their opponents.

Service
Originally known as the First West Tennessee U.S. Cavalry, the 6th Tennessee Cavalry was organized at Bethel Springs, LaGrange, Bolivar, and Trenton, Tennessee and mustered on 11 August 1862 for a three-year enlistment under the command of Colonel Fielding Hurst. These last four companies of the regiment were mustered in October 1862, as the 1st West Tennessee Infantry and transferred to the 6th Tennessee Cavalry in July 1863, per orders dated 10 June 1863.

The regiment was attached to District of Jackson, Department of the Tennessee, to November 1862. District of Jackson, XIII Corps, Department of the Tennessee, to December 1862. Cavalry Brigade, District of Jackson, XVI Corps, to March 1863. Cavalry Brigade, 3rd Division, XVI Corps, to June 1863. 2nd Brigade, 1st Cavalry Division, XVI Corps, to December 1863. 1st Brigade, 1st Cavalry Division, XVI Corps, to June 1864. Unassigned, District of West Tennessee, Department of the Tennessee, to November 1864. 2nd Brigade, 4th Division, Cavalry Corps, Military Division Mississippi, to December 1864. 2nd Brigade, 7th Division, Cavalry Corps, Military Division Mississippi, to February 1865. 1st Brigade, 6th Division, Cavalry Corps, Military Division Mississippi, and District of Middle Tennessee, to August 1865.

Recent scholarship and the discovery of the diary of Lt. Colonel William K.M. Breckenridge, proved that Breckenridge, not Hurst, was actually responsible for the effective organization and equipping of the regiment. According to the 2020 work, In The Shadow of the Devil: William K.M. Breckenridge in Fielding Hurst's First West Tennessee U.S. Cavalry, Breckenridge traveled tirelessly in his efforts to equip and prepare the regiment for action. Breckenridge's diary, as well as other official sources, showed that while Breckenridge was working to equip the unit, Hurst was arrested for arson after burning homes of political and wartime opponents.

From the fall of 1862 through his death in October 1863, it seems apparent from existing sources that Breckenridge was the most active of the two commanders in actually leading the unit. Hurst's entire career with the unit was mired in controversy and intrigue. He would ultimately be forced to resign. While he cited ill health as the reason, his resignation came after a humiliating defeat at the battle of Bolivar, Tennessee and after many instances of insubordination to more senior Union Army officers.

The 6th Tennessee Cavalry mustered out of service 26 July 1865.
