25th Cavalry Regiment [also called 3rd Texas Lancers] was organized by C.C. Gillespie early in
1862. The unit was soon dismounted and ordered to Arkansas. Here it was captured in January,
1863, at Arkansas Post.
After the exchange the regiment was consolidated with the 17th, 18th, and 24th Texas Cavalry
Regiments (dismounted) and was placed in Deshler's, J.A. Smith's, and Granbury's Brigade,
Army of Tennessee. This command fought with the army from Chickamauga to Atlanta, moved with Hood to
Tennessee, and saw action in North Carolina. The 25th was organized with about 900 men and
had 552 in action at Arkansas Post. At Chickamauga the 17th/18th/24th/25th suffered 200
casualties and in December, 1863, totalled 690 men and 520 arms. Only a remnant surrendered on
April 26, 1865. The field officers were Colonel Clayton C. Gillespie, Lieutenant Colonel William
M. Neyland, and Majors Joseph N. Dark and Edward B. Pickett.
