Fort Duncan
Eagle Pass, TX
Fort Duncan was established in 1849 by Captain S. Burbank of the First U.S. Infantry to guard the Rio Grande frontier and the western lines of communication opened after the Mexican-American War. Federal troops garrisoned the post until the eve of the Civil War in 1861 and returned in 1868, and it later became known as Camp Eagle Pass. It stood as a linchpin of American military presence on the border for more than a century.
