John Horse
Brackettville, Kinney County, Texas
Marker Inscription
Born in Spanish Florida of a black mother and Seminole father in 1812, John Horse (also known as Juan Caballo, Juan Cavallo, or Gopher John) was a prominent leader of Seminole blacks during the 2nd Seminole War. After a valiant fight alongside Seminole Chief Coacoochee (known as Wild Cat), and emancipation by Gen. Thomas S. Jesup, John Horse was removed to the Indian Territory (present-day Oklahoma) with hundreds of his people in June 1838, but within a short time John was back in Florida serving the U.S. Army as interpreter, scout, combatant and as a mediator with Seminoles in the latter part of the war. For his services, John was officially granted his freedom by future President Gen. Zachary Taylor. From his new home in Indian Territory John Twice journeyed to Washington, D.C., to plead his people’s case to the Commissioner of Indian Affairs. Years later John claimed he and Gen. Jesup met with Pres. Polk to discuss the plight of the Seminoles. In late 1849, oppressed and hunted after their freedom was withdrawn by the federal government, two groups of Seminoles and blacks, led by horse and Coacoochee, slipped out of Indian Territory into Texas, en route to freedom in Mexico. The band rested briefly here at Las Moras Spring in early July 1850. In time, John settled his group at Nacimiento on land made available by the Mexican government. In exchange, the Seminoles provided protection from Apache and Comanche. When the Seminole Scout Detachment was formed at Fort Duncan in 1870, John returned to Texas. In 1876, while living in the Seminole Camp at Fort Clark, John survived a third attempt on his life in an ambush near this site. After recovering, he returned to Nacimiento, Mexico. Following a trip to meet with Pres. Porfirio Diaz to plead for his people’s permanent land rights in Nacimiento, he died in Mexico city in 1882 at the age of 70.

The Story
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.
Why it matters
John Horse's life traces the extraordinary struggle of the Black Seminoles for freedom across Florida, Indian Territory, Texas, and Mexico, binding together the histories of slavery, Native resistance, and the borderlands.
The story behind this marker
AI contextThe era
John Horse was born in Spanish Florida in 1812, into one of the most remarkable communities in early American history: the world of the Black Seminoles. These were people of African descent — some escaped from slavery, some born free among the Seminoles — who lived alongside and among the Seminole people in the swamps and hammocks of Florida, forming their own settlements and their own bonds of kinship and alliance. His mother was Black and his father Seminole, and that dual inheritance shaped a life lived across the color lines that the United States was trying to draw ever harder.
The backdrop of his early life was the long, brutal effort of the United States to seize Florida, remove its Native peoples, and reclaim the freedom-seekers who had found refuge there. The Second Seminole War, one of the longest and costliest of the wars of Indian removal, was fought in large part over exactly this: the people the U.S. wanted to force west, and the Black Seminoles who had everything to lose if slavery followed them.
His later years unfolded against the shifting, dangerous ground of the borderlands — Indian Territory, the Texas frontier, and northern Mexico — where the promises of one government were routinely undone by the next, and where a people's freedom could be granted, withdrawn, and hunted within a single lifetime.
People & events
John Horse's life reads like an epic of endurance. He fought in the Second Seminole War alongside the Seminole chief Coacoochee — Wild Cat — and won a reputation as a leader of his people. After being emancipated by General Thomas S. Jesup and removed west to Indian Territory in 1838, he did something extraordinary: he returned to Florida, this time serving the U.S. Army as interpreter, scout, combatant, and mediator with the Seminoles in the war's closing chapters. For that service, the future president Zachary Taylor formally granted him his freedom.
But freedom, he learned again and again, was not a thing that stayed granted. He journeyed twice to Washington to plead his people's case before the Commissioner of Indian Affairs, and by his own account met with President Polk about the Seminoles' plight. When federal protection collapsed and his people were once more oppressed and hunted, he and Coacoochee led two bands of Seminoles and Black Seminoles out of Indian Territory in 1849, striking south across Texas toward the one place that offered freedom: Mexico.
The marker notes that the band rested at Las Moras Spring in the summer of 1850 on that long road to sanctuary. He settled his people at Nacimiento on land the Mexican government made available, and in return the Seminoles guarded the frontier against Apache and Comanche raids. When the U.S. Army formed a scout detachment at Fort Duncan in 1870, he came back to Texas — and in 1876 survived a third attempt on his life in an ambush near this very site. He recovered, returned to Mexico, and died in Mexico City in 1882 at seventy, after traveling to petition President Porfirio Díaz for his people's permanent land rights.
Its place in the American story
John Horse's story braids together three strands of American history that are usually told apart: slavery, Native resistance, and the making of the borderlands. He belonged to a community that refused the country's insistence that a person be only Black or only Indian, only free or only enslaved, and his whole life was a moving argument that freedom was worth crossing any border to reach.
His repeated journeys — Florida to Indian Territory, back to Florida, west again, then south into Texas and across into Mexico — trace the geography of removal and escape that defined the mid-nineteenth-century United States. That his people ultimately found their surest freedom by leaving the country entirely is a sobering measure of how conditional American liberty could be for those it was built to exclude.
The later chapter — the Seminole scouts recruited at Fort Duncan — folds his community into the story of the frontier army and its Black soldiers, whose service on the western borderlands has too often gone unrecognized. His life connects the swamps of Florida to the springs of Texas to the Sierra of Coahuila, and insists that all of it is one American story.
If you visit
This is borderland country, wide and dry and quiet, near Brackettville in Kinney County — the kind of landscape where you feel the distances a fugitive band would have measured on foot and horseback. Come thinking about water: springs like Las Moras were lifelines on these routes, the reason a hunted people could rest and go on.
Stand near the marker and read the whole arc it compresses — Florida, Washington, Indian Territory, Texas, Mexico City — and let the sheer span of it settle in. The ground here saw one chapter of a life lived across a continent, including the 1876 ambush he survived nearby. There is a solemnity to knowing a place witnessed both danger and survival.
It pairs naturally with the broader Seminole scout history of the Fort Clark and Fort Duncan area, and with a wider drive along the Texas–Mexico frontier. Go slowly, notice how far it is between water and shade, and you'll understand better than any book why freedom, for the Black Seminoles, so often lay on the far side of a border.

Fort Clark
Brackettville, TX
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.
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.
