Established by Captain Sidney Burbank, First U.S. Infantry, on March 13, 1849, this post was named in honor of Lieutenant Zebulon M.P. Inge, who fell at Resaca de la Palma on May 9, 1846. It protected the Southern Overland Stage mail route from Indian raids. Federal troops, withdrawn in 1861, reoccupied the post from 1866 to February 28, 1869. It later became a Texas Ranger camp.
