Fort Gates, was a United States Army fort established on October 26, 1849 as Camp Gates by Captain William Reading Montgomery and two companies of the Eighth United States Infantry. The fort was located on the north bank of the Leon River about five miles east of the site of present Gatesville, Texas. The installation was named for Brevet Major Collinson Reed Gates of New York, a noted officer in the Battle of Palo Alto and the Battle of Resaca de la Palma. The fort was established to protect settlers on the Texas frontier from Indians. The fort was garrisoned by companies D, I, F, and H of the Eighth United States Infantry. In April 1851, 256 enlisted men and forty-five officers were stationed at Fort Gates, the most reported in a single month.
