Rio Grande City, C.S.A.
Rio Grande City, Starr County, Texas
Marker Inscription
An official Confederate port of entry, customhouse and major terminus of the cotton road to Mexico. Cotton was the one great money crop of the South that could be sold to hungry European mills for cash for necessary arms, munitions, drugs that had to come from Europe. International ports on the Rio Grande were the South's frail lifelines, its last resource in a war with an industrialized North that manufactured for its self what the South had to import. Cotton arrived at this booming border town on wagons and oxcarts after a hot and dusty trip. It was then ferried across the river and delivered to the neutral ships anchored in the Gulf. Teamsters loaded vital leather goods, clothing, blankets, guns, ammunition and medical supplies for the return trip. Troops from nearby Fort Ringgold guarded the wagon trains and town from bandit raids. In November 1863 Federal forces captured Brownsville and the 1st Texas Union Cavalry advanced up river, captured and occupied this town, seizing the cotton awaiting entry. Rio Grande City was reoccupied in May 1864 and used as a supply and reserve base for the recapture of Brownsville. There was constant danger here from raids by Mexican guerrillas paid by enemy agents to make trouble in Texas. Draft evaders, Union sympathizers and those wanting to avoid conflicts of war tried to cross the river here. In an arrangement with Mexican officials, Confederates both required and checked passports to curb desertions and smuggling.

The Story
During the Civil War, this booming border town on the Rio Grande served as a Confederate port of entry and customhouse — a key terminus of the "cotton road" that funneled Southern cotton to neutral ships in the Gulf and returned with European arms, medicine, and supplies. Blockaded on every ocean coast, the Confederacy depended on this frail international lifeline through Mexico. Federal troops seized the town in 1863, and it changed hands again in 1864 amid raids, smuggling, and cross-border intrigue.
Why it matters
It reveals a little-known theater of the Civil War, where the outcome hinged not on famous battlefields but on a smuggling route along an international river that kept the Confederacy armed.

Fort Ringgold, C.S.A.
Rio Grande City, TX
Early in the Civil War, Confederate Texans under Col. John S. Ford occupied Fort Ringgold on the Rio Grande, a vital link in the chain of posts guarding Texas's vast frontier, coastline, and border. From here commanders like Ford, August Buchel, and Santos Benavides scouted the river, defended ranches, and protected the cotton wagons trading through neutral Mexico for war supplies. Union cavalry seized the fort in late 1863, but Ford retook it in May 1864 and used it as a springboard to recapture Brownsville.
Memorial Hospital
Roma, TX
Erected in 1853 by E. R. Hord—a state representative and later U.S. congressman—this sturdy building on the Rio Grande has walls 28 inches thick, its stone hauled in by ox-teams and its beams landed by boat at a nearby dock. During the Civil War the structure served as a military headquarters in the contested border country. It was recorded as a Texas Historic Landmark in 1965.
Peñitas Cemetery
Peñitas, TX
Established in 1836, Peñitas Cemetery served the settlers of one of the Rio Grande Valley's historic communities, with its earliest marked grave dating to 1894 and older unmarked burials likely beneath. Among those resting here are two Tejano Union veterans of the Civil War — Private José María Loya and Sergeant Ignacio Zamora — alongside pioneer families and veterans of other wars. Marble tombstones, homemade crosses, and religious statues mark the graves, still tended by residents.
McAllen Ranch
Linn, TX
The McAllen Ranch reaches back to Spanish colonial Texas, when José de Escandón's Nuevo Santander opened the lower Rio Grande and José Manuel Gómez received the vast 95,000-acre Santa Anita grant in 1790. Through marriages and shrewd purchases, the grant passed to María Salomé Ballí, who with Irish immigrant John McAllen reunited and expanded the holdings to more than 160,000 acres, supplying beef and hides—and refuge—to both sides during the Civil War. Run under the SM brand by her descendants, it became one of the oldest Texas ranches in continuous family operation.
