Colonel Jacob B. Biffle was originally lieutenant colonel, 2nd (Biffle's) Battalion; then colonel of 6th (1st) Tennessee Cavalry Regiment; into which his battalion was merged in May, 1862. When this regiment was reorganized June 12, 1862, with James T. Wheeler elected as colonel, Biffle set out to raise a new regiment, which had no connection with the other two organizations except for the fact that Biffle was at different times commanding officer of all three. He completed organization of the regiment, and was commissioned as its colonel, as of October 3, 1862.
The 19th Cavalry served in J.B. Biffle's and Dibrell's Brigade, and fought at Parker's Cross Roads
