El Fortin de San Jose
Presidio vicinity, Presidio County, Texas
Marker Inscription
About 1773, the Spanish garrison at Presidio del Norte, present Ojinaga, Mexico, established El Fortin de San Jose in this vicinity to protect local farmers. The settlement retained the name after the post was abandoned about 1810. After Ben Leaton had acquired extensive property in the area in 1848, the community came to be called Fort Leaton. Ben Leaton's fortress is all that remains of the old settlement. Fort Leaton is neither the site of the original Presidio del Norte nor the Spanish mission Apostal Santiago, as stated erroneously by earlier markers at this location. (1978)

The Story
Around 1773 the Spanish garrison across the Rio Grande at Presidio del Norte set up El Fortín de San José on this side to shield local farmers, and the settlement kept the name even after the post was abandoned about 1810. When Ben Leaton acquired extensive property here in 1848, the place became known as Fort Leaton, and his adobe fortress is all that survives of the old community. The marker pointedly corrects earlier signs: this is neither the original Presidio del Norte nor the Spanish mission Apóstol Santiago.
Why it matters
The site marks the far northern edge of Spain's colonial frontier in Texas, where a small garrison tried to protect farming families in contested borderland country.
The story behind this marker
AI contextThe era
The stretch of the Rio Grande around Presidio is one of the oldest farmed places in North America. Near here the Río Conchos flows in from Mexico and meets the Rio Grande, at a spot the Spanish called La Junta de los Ríos. Indigenous farmers had lived along these riverbanks for centuries before any European arrived, growing crops in the rich bottomlands in the middle of the Chihuahuan Desert.
In the 1700s this valley sat at the far northern edge of New Spain. The Spanish crown built presidios, or fortified garrisons, along the frontier to protect missions and settlers and to push back raids by Apache and Comanche bands. Presidio del Norte, on the south bank where the Mexican town of Ojinaga stands today, was one of these posts. Its soldiers had to cover huge distances with few men and thin supplies.
The borderland changed hands several times in the next century. Spanish rule gave way to an independent Mexico in 1821. After the U.S.–Mexican War of 1846–1848, the Rio Grande became an international border, and the north bank became part of the United States. This small settlement lived through each of those changes.
People & events
Around 1773, soldiers from Presidio del Norte set up a small outpost on this side of the river and named it El Fortín de San José, the little fort of Saint Joseph. Its job was practical: to protect the farmers working the fields here from raids. It was never a grand fortress. It was a guard post meant to keep a farming community alive on an exposed frontier.
The garrison left around 1810, the year Mexico's war of independence from Spain began. The name stayed with the community anyway. People went on farming the valley, and "San José" survived in local use for decades after the soldiers were gone.
The next big change came after the U.S.–Mexican War, when American traders and settlers moved into the new border region. In 1848 a man named Ben Leaton acquired large landholdings here and built a massive adobe compound that was part home, part trading post, and part stronghold. Leaton was a frontier trader with a rough and much-debated reputation, and his fortress soon gave the whole community a new name: Fort Leaton. That adobe building is the only part of the old settlement still standing. The 1978 marker makes a point of correcting earlier signs: this site is not the original Presidio del Norte, and it is not the Spanish mission of Apóstol Santiago.
Its place in the American story
El Fortín de San José is a small piece of a very large story: how Spain tried to hold a frontier that stretched from the Gulf of Mexico to California. Posts like this one were often just a handful of soldiers protecting a few farms, but they are part of the reason the Southwest still has Spanish place names, mission churches, and communities with roots older than the United States.
The site's later history follows the region into American hands. Ben Leaton's arrival right after 1848 reflects the rush of traders, freighters, and fortune-seekers into lands the United States had just won from Mexico. His adobe fortress sits on top of a much older Spanish and Indigenous landscape, and the layers show how the borderlands kept changing while many of the same families went on farming the same ground.
The marker is also unusual because it corrects the record, and openly. It admits that earlier markers got the site wrong. History is not fixed, and careful research sometimes overturns what people once believed. This marker is honest about that.
If you visit
This marker stands near Fort Leaton, just outside the border town of Presidio, on the road that follows the Rio Grande toward Big Bend. Ben Leaton's adobe fortress is preserved as a state historic site. Its thick earthen walls and shaded rooms give you a real sense of how people survived both the desert heat and the dangers of frontier life. Check current visiting details before you go.
As you look around, keep in mind that the adobe building is the youngest layer here. Under it and around it is a Spanish guard post from the 1770s, and older still, farming communities that worked this river valley long before that. The green strip of irrigated land along the river, surrounded by desert, shows why this spot mattered to so many people.
The drive along the river road west of Presidio is among the most spectacular in Texas, with canyons, mesas, and the Rio Grande running close alongside. Fort Leaton makes a natural first or last stop on a trip through Big Bend country. This is remote territory, so carry water, keep your tank full, and allow plenty of time.

Apache Last Stand
Presidio County, TX
On June 12, 1880, in the rugged Big Bend country of Presidio County, four Pueblo Indian scouts serving under General Benjamin H. Grierson fought and turned back a band of twenty Apache warriors. The marker records it as the last Apache stand in the county — a small but telling episode in the long, grinding conclusion of the Indian Wars in far West Texas. It reflects the era when the U.S. Army relied heavily on Native scouts to fight other Native peoples.
Fort Pena Colorada (Red Rock)
Marathon, TX
Established in 1880 in the rugged Big Bend country, Fort Peña Colorada guarded the water and passes near Marathon against raids across the Mexican border. Apaches struck the post in 1881 during the last years of the Indian Wars in far West Texas. With the frontier considered pacified, the fort was abandoned in 1893.
Smith-Carlton Adobe House
Fort Davis, TX
In 1873, a former Buffalo Soldier of the 24th U.S. Infantry named Archie Smith claimed 160 acres near Dolores Mountain in the Trans-Pecos country and raised an adobe home with native oak beams. Its vaulted room served as a family chapel open to neighbors of every denomination before the town's first Catholic church was built. Later owners, the Carltons, preserved and eventually restored the structure, which survives as the oldest home still lived in at Fort Davis.
Fort Davis
Fort Davis, TX
Fort Davis was established in 1854 to guard travelers on the San Antonio–El Paso Road and named for Jefferson Davis, then U.S. Secretary of War. Federal troops abandoned it at the outbreak of the Civil War in 1861 and reoccupied it in 1867, after which its soldiers—including Black regulars—helped bring stability to the far West Texas frontier until the post was deactivated in 1891. Its ruins and restored buildings remain among the best-preserved frontier military posts in the Southwest.
