Later, Confederates abandoned and destroyed most of fort and equipment, except for hospital and medical supplies left for their sick and wounded. Federals occupied fort, July 4, 1862, and later escorted the recovered patients by horseback and ambulance over 500 miles down the Rio Grande to Fort Clark. Federals held the trans-Pecos area longer than any other part of Texas. (1964)
