Hardy's Tennessee Squadron was a temporary organization, formed in December, 1862, by order of Major General John P. McCown, to serve as his escort. It was composed of three companies. In the Battle of Murfreesboro, December 31, 1862, General McCown sent his escort to tie up with Brigadier General John A. Wharton's Cavalry Division on December 30, 1862, and the squadron operated with Wharton's Division on the 31st, participating in a charge made by Ashby's 2nd Regiment. Captain Hardy was commended by General Wharton for his actions on that day. Following the battle, the Squadron went into camp at Shelbyville, with McCown's Division.
