Fort Clark
Brackettville, Kinney County, Texas
Marker Inscription
A strategic installation in the U.S. Army's line of forts along the military road stretching from San Antonio to El Paso, Fort Clark was established in June 1852. Located near natural springs and Las Moras Creek, its site was considered a point of primary importance to the defense of frontier settlements and control of the U.S. Mexico border. Many infantry regiments and almost all cavalry regiments were at one time based at Fort Clark, as well as companies of Texas Rangers and Confederate troops during the Civil War. The Army's Seminole-Negro Indian Scouts also were assigned to Fort Clark, and with black troops of the 10th Cavalry and 24th and 25th infantry played a decisive role in the Indian campaigns of the 1870s. Prominent military leaders who served here include Col. Ranald S. Mackenzie, Gen. Wesley Merritt, Gen. William R. Shafter, Gen. John L. Bullis, Gen. Zenas R. Bliss, Gen. Jonathan M. Wainwright, and Gen. George S. Patton, Jr. Fort Clark remained a horse-cavalry post for the U.S. Army through World War II and finally was inactivated in 1946. The fort property, including many native stone buildings constructed by civilian craftsmen in the 1870s, was listed in the National Register of Historic Places in 1979. (1994)

The Story
Established in 1852 beside the springs of Las Moras Creek, Fort Clark guarded the military road from San Antonio to El Paso and the border with Mexico. Nearly every U.S. cavalry regiment passed through, and its garrison — including the Seminole-Negro Indian Scouts and the Buffalo Soldiers of the 10th Cavalry and 24th and 25th Infantry — played a decisive part in the Indian campaigns of the 1870s. Held briefly by Confederates during the Civil War, the fort remained a horse-cavalry post until 1946.
Why it matters
Fort Clark condenses a century of the frontier army into one site, where Black regulars, Native scouts, and future generals like Patton all served in the long contest over the Texas borderlands.
The story behind this marker
AI contextThe era
After the U.S.-Mexican War ended in 1848, the United States found itself responsible for a long new border and a huge, lightly settled frontier in West Texas. The Army built a chain of forts along the military road from San Antonio to El Paso to protect travelers, freight wagons and settlers, and to assert control over the border region. Fort Clark was founded in June 1852 as one link in that chain.
The site was chosen for water. Las Moras Creek and its natural springs were precious in this dry country, and whoever held them held a strategic position. The fort protected frontier settlements and watched over the border with Mexico, a region where the United States, Mexico and several Native nations, including Comanche, Apache and Kickapoo peoples, all had competing stakes.
The post's history runs through the major chapters of the nineteenth-century Southwest. Confederate troops held it during the Civil War. After the war, U.S. forces returned, and the 1870s brought the intense Indian campaigns that the fort is best known for. It then lasted well into the twentieth century as a horse-cavalry post, a living link to the old frontier army until it was finally inactivated in 1946.
People & events
Fort Clark's most remarkable soldiers may be the Seminole-Negro Indian Scouts. They were descendants of Black Seminoles, people of African descent who had lived and allied with the Seminole in Florida and later moved west and into Mexico. Recruited by the Army for their tracking skill and knowledge of the country, the scouts became famous for their ability in the field, and several were awarded the Medal of Honor. Their story joins African American and Native American history in a way few others do.
Alongside them served Black regulars of the 10th Cavalry and the 24th and 25th Infantry, the troops widely known as Buffalo Soldiers. Together with the scouts they played a decisive part in the Indian campaigns of the 1870s. Lt. John L. Bullis, who rose to general, became closely associated with leading the scouts. Col. Ranald S. Mackenzie, one of the Army's most aggressive frontier commanders, also operated from Fort Clark in these years.
The list of officers who passed through reads like a history of the U.S. Army. Along with Mackenzie and Bullis it includes Wesley Merritt, William R. Shafter and Zenas R. Bliss, and later two twentieth-century figures: Jonathan M. Wainwright, remembered for his role in the Philippines in World War II, and George S. Patton, Jr., one of that war's most famous generals. Many civilian craftsmen worked here too, building the native stone buildings of the 1870s that still define the post.
Its place in the American story
Fort Clark sums up the U.S. Army's long presence on the frontier in one place. Across its nearly century-long life it saw antebellum border defense, Confederate occupation, the campaigns of the 1870s and the last days of the horse cavalry. Few places show so clearly how the Army shaped the settlement and borders of the American West.
Its story also brings forward people who were often left out of the popular frontier myth. Black soldiers and the Seminole-Negro Indian Scouts were central to the Army's work here, not side notes to it. Their service, in a country that denied them full citizenship and equal treatment, is an important and complicated chapter of American history.
That history is complicated in another way too. The campaigns these soldiers fought were part of the conquest of Native peoples and the loss of their homelands. Fort Clark is a place to face both the courage and skill of the men stationed here and the lasting cost of the wars they waged. Its listing on the National Register of Historic Places in 1979 recognizes how much of this story is still written in its stones.
If you visit
The native stone buildings are the heart of the experience. Many were put up by civilian craftsmen in the 1870s, and their solid, handsome masonry still gives the old post a strong sense of place. Walk the grounds, picture the parade of cavalry that passed through, and look for how the buildings reflect the frontier Army's daily life.
Much of the former fort is now a residential and resort community, so check ahead about what is open to visitors and respect private property. The springs and Las Moras Creek that drew the Army here in the first place are still part of the setting, and they help explain why the site mattered so much in such dry country.
In the Brackettville area, look for places tied to the Seminole-Negro Indian Scouts, whose descendants kept their community's history alive for generations. Fort Clark fits well on a West Texas road trip along the old frontier corridor, where other forts from the same defensive line let you trace the Army's chain of posts across the region.

John Horse
Brackettville, TX
Born in Spanish Florida in 1812 to a Black mother and a Seminole father, John Horse became a leading figure among the Black Seminoles during the Second Seminole War, fighting alongside Chief Coacoochee before serving the U.S. Army as scout, interpreter, and mediator. Repeatedly pursued after his people's freedom was stripped away, he led followers out of Indian Territory in 1849 toward sanctuary in Mexico, resting near Las Moras Spring in 1850 and later settling at Nacimiento in exchange for guarding the border against Apache and Comanche raids. He survived an ambush near this site in 1876 and died in Mexico City in 1882.
Seminole Scout Camp on Fort Clark
Brackettville, TX
For decades the descendants of Africans who had fled slavery for Spanish Florida — where they joined the Seminole people and forged the distinct Black Seminole community — carried their hard-won freedom across the continent. After removal to Indian Territory and a sojourn in Mexico, one group crossed back into Texas in 1870 to serve the U.S. Army as the Seminole-Negro Indian Scouts. They made their home at 'the camp' on Fort Clark, building jacal houses and digging irrigation ditches along Las Moras Creek while scouting the border country until their disbandment in 1914.
Seminole Indian Scouts' Cemetery
Brackettville, TX
Established on the Fort Clark reservation in 1872, this cemetery holds the graves of the Seminole Negro Indian Scouts and their families. Descendants of Seminoles and formerly enslaved people who had come from Florida around 1850 and lived in Mexico and Texas, these scouts served under Lieutenant John L. Bullis and Colonel Ranald S. Mackenzie in the frontier campaigns of the 1870s, and four of them earned the Medal of Honor.
Seminole-Negro Scouts
Del Rio, TX
From 1870 to 1881, roughly a hundred Seminole-Negro Scouts served the U.S. Army along the Texas border at Forts Duncan and Clark and Camp Del Rio. Mostly descendants of runaway slaves who had intermarried with Florida Seminoles before removal to Indian Territory, they were prized for extraordinary tracking skill, courage, and endurance on the trail. Under Lieutenant John L. Bullis they fought for eight years without losing a single scout, and four earned the Medal of Honor.
