Brazos Santiago, C.S.A.
South Padre Island, Cameron County, Texas
Marker Inscription
Brazos Santiago Pass, to south of this spot, was important Confederate harbor-entry during the Civil War. On island across the pass were fort and town of Brazos Santiago, where on Feb. 21, 1861, Texas troops under Col. John S. Ford captured the U.S. depot with mortars, siege guns and ordnance. A Confederate battery was then set up. In March 1861, off the bar, on U.S.S. "Daniel Webster", E.B. Nichols and Maj. Fitzjohn Porter, acting for Texas and the U.S., arranged Federal evacuation of the Rio Grande. Blockade ships arrived Dec. 1861. Col. Ford shifted forces to Brownsville. Gen. J.B. Magruder, C.S.A., ordered blasting of lighthouse north of pass, 1862. Trade vital to Confederacy plied from Cuba, Europe, Asia to Bagdad, Mexico, often actually slipping into Brazos Santiago Pass. Harbor sheltered blockade runners 1861-64. On May 10, 1863, U.S.S. "Brooklyn" destroyed schooners in the harbor. Late 1863, French warships banned war material in Bagdad, and Mexican steam lighters ran guns from sea vessels into Brazos Santiago. Nov. 2, 1863, Gen. N.P. Banks landed U.S. Army here, took line of Rio Grande forts. Refortified Brazos Island and made it terminus for Army railroad to Rancho Blanco on Rio Grande. When C.S.A. retook Rio Grande Line in 1864, Federals in Brownsville were thrown back to Brazos Island. Col. Theodore H. Barrett, with troops from here, marching on Brownsville in May 1865, was confronted by Col. Ford's Confederates at Palmito Hill and fought last engagement of the Civil War.

The Story
Guarding the mouth of the Rio Grande, Brazos Santiago Pass became one of the Confederacy's most vital lifelines during the Civil War. With the Union blockade choking Southern ports, cotton and war material moved through neutral Mexican Bagdad and slipped into this pass from Cuba, Europe, and beyond, keeping the Trans-Mississippi supplied. The region changed hands repeatedly, and troops staged from Brazos Island fought at Palmito Hill in May 1865 — the last land engagement of the war, weeks after Appomattox.
Why it matters
This remote pass shows how the Civil War was won and lost not only on famous battlefields but along contested supply lines, and it witnessed the war's final shots.

Point Isabel, C.S.A.
Port Isabel, TX
After Texas joined the Confederacy, the U.S. Navy blockaded this Gulf port in late 1861, choking off commerce and driving customs offices and civilians away. The old lighthouse became a watchtower for blockade runners who used Laguna Madre as a haven, and the port changed hands repeatedly — Federal forces occupied it in 1863, Confederates drove them out in 1864, and in 1865 Union General Lew Wallace, later author of "Ben Hur," met Confederate officers here to discuss peace. Mexican lighters even ran Confederate arms ashore in defiance of both French and U.S. patrols.
Old Point Isabel Lighthouse
Port Isabel, TX
Raised by the federal government in 1852, this lighthouse guided the busy commerce of the Rio Grande's mouth, where steamboats and coastal traders converged. Its light went dark during the Civil War and flickered in and out of service for decades before being permanently extinguished in 1905, a small monument to the rise and decline of Gulf maritime trade.
These Palmetto Pilings
Brownsville, TX
These weathered pilings mark two separate military supply roads a generation apart. The cypress piles are remnants of a floating bridge Gen. Zachary Taylor threw across Boca Chica Inlet in 1846 during the Mexican-American War; the palmetto pilings are what remains of a railroad crossing begun by Gen. Francis Herron in 1864 and finished by Gen. Philip Sheridan in 1865 to move Union supplies at the close of the Civil War.
Battle of Palmito Ranch
Brownsville, TX
On May 12–13, 1865 — more than a month after Lee's surrender at Appomattox — Union and Confederate forces clashed near this spot in the last land engagement of the Civil War. Federal troops advancing from Brazos Island toward Fort Brown were checked by Confederate cavalry under Col. John S. "Rip" Ford until his artillery and a flanking charge forced a Union retreat. In a strange coda to a war already lost, the Confederates carried the field, reporting no fatalities while Union losses ran to more than a hundred.
