Erected by the State of Texas In Memory of Colonel Robert M. Coleman Signer of the Texas Declaration of Independence Aide-de-camp to General Sam Houston at San Jacinto Colonel of the first regiment of Texas Rangers Born in Kentucky in 1799 Drowned at the mouth of the Brazos in July 1837

The Story
Kentucky-born Robert M. Coleman came to Texas in time to sign the Texas Declaration of Independence and serve as aide-de-camp to General Sam Houston at the decisive Battle of San Jacinto in 1836. He went on to command the first regiment of Texas Rangers before drowning at the mouth of the Brazos River in 1837. This state memorial honors a founder of the Republic of Texas whose life was cut short in its earliest years.
Why it matters
Coleman's career—declaration signer, San Jacinto officer, and Ranger commander—ties together the political and military birth of the Republic of Texas.
The story behind this marker
AI contextThe era
Robert M. Coleman's story belongs to the birth of the Republic of Texas, one of the most compressed and dramatic passages in American history. In the mid-1830s, Anglo settlers and Tejanos in the Mexican province of Texas moved from grievance to open revolution, and within a matter of months a new nation declared itself into being and then had to win the battlefield to make the declaration real.
Coleman was born in Kentucky in 1799 and, like many of the men who shaped early Texas, came from the American frontier states to a place that was itself a frontier. The Texas of these years was thinly settled, contested ground, where the line between soldier, statesman, and settler blurred and a single person might be all three within the space of a year.
The drama reached its climax in the spring of 1836. In March the revolutionaries adopted a declaration of independence; in April the decisive battle was fought and won. Coleman was present for both the political and the military hinge of that year — a rare vantage on the exact moment a republic came into existence.
People & events
The marker sketches a life lived at the center of great events. Robert M. Coleman put his name to the Texas Declaration of Independence in March 1836, joining the signers who formally severed Texas from Mexico. Then, at the Battle of San Jacinto that April, he served as aide-de-camp to General Sam Houston in the short, ferocious fight that secured Texas independence — moving from the council chamber to the field within weeks.
Afterward he took up the work of defending the young republic as colonel of its first regiment of Texas Rangers, the frontier force charged with guarding scattered settlements. It was a role that placed him on the raw edge of the new nation, where the fighting did not simply stop because independence had been declared.
His life ended abruptly and young. In July 1837, Coleman drowned at the mouth of the Brazos River, dead at only thirty-eight, barely a year after the triumph at San Jacinto. The marker was raised by the State of Texas in his memory — the state's own acknowledgment of a founder whose service was crowded into a handful of extraordinary years.
Its place in the American story
Coleman's career braids together the two threads that make up the founding of any nation: the political and the military. He signed the document that declared Texas free and then helped win the battle that made the declaration stick. Few lives connect those two acts so directly, and that is precisely why a state chose to remember his.
The Republic of Texas he helped create occupies a singular place in the American story. For nearly a decade Texas stood as an independent nation before joining the United States, and the men who founded it — including the signers and the officers of San Jacinto — became the republic's equivalent of founding fathers. Their names anchor the origin story of what would become one of the largest states in the Union.
Coleman's command of the first regiment of Texas Rangers also links him to an institution that grew into an American legend. Born of the practical need to defend a frontier republic, the Rangers would become one of the most storied law-and-order forces in the country's history. To have led its first regiment is to stand at the headwaters of that long tradition.
If you visit
This is a monument rather than a house or a church, so what you are visiting is memory itself — the deliberate choice of a state to mark a life it did not want forgotten. Read it as such, and let the sparse, almost epitaph-like lines do their work: birth in Kentucky, a signature on a declaration, a general's side at a decisive battle, a command on the frontier, and an early death by water.
The setting gives the ending its weight. You are near the mouth of the Brazos River, on the Texas coast where the river meets the Gulf — the very place where Coleman drowned in 1837. Stand within sight of that water and the last line of his story stops being an abstraction.
It makes a fitting stop on any route that follows the founding of Texas. Pair the spot in your mind with the events the marker names — a declaration in the spring of 1836, a battle weeks later — and this quiet coastal memorial becomes a bookend to a life that helped bring a republic into being.

Four Miles Southeast to the Original Town of Velasco
Freeport, TX
Four miles from this spot stood the original town of Velasco, one of early Texas's most consequential coastal sites. Here the schooner Lively landed the first immigrants to Stephen F. Austin's colony in 1821; here colonists and Mexican troops clashed in the 1832 Battle of Velasco, an early spark of Texan resistance; and here, in 1836, Presidents David G. Burnet and Santa Anna signed a peace treaty that Mexico never ratified. Few places hold so many turning points of the Texas Revolution in one stretch of shoreline.
Site of Town of Old Velasco
Freeport, TX
Long before Freeport rose nearby, the town of Velasco stood at the mouth of the Brazos River as one of the earliest gateways into Anglo Texas, funneling more than 25,000 settlers into Stephen F. Austin's colonies between 1821 and 1835. In 1832 it became the scene of an early armed clash between colonists and Mexican forces, an ember of the coming Texas Revolution. By the mid-1800s the same coastline had reinvented itself as a breezy resort for wealthy plantation families, before the Civil War and an 1875 hurricane hollowed the town out for good.
William Jarvis Cannan
Freeport, TX
Born in Edgefield, South Carolina in 1808, William Jarvis Cannan came to Texas in 1835 and joined the army in time to fight in the decisive victory at San Jacinto in April 1836. For his service he received headright and bounty lands across several Texas counties, and he raised eleven children by his two marriages before his death in 1881.
The Lively
Surfside Beach, TX
This stretch of the Brazoria County coast witnessed three turning points in early Texas history. Here, according to the marker, the first ship of colonists bound for Stephen F. Austin's colony came ashore in December 1821; here the Battle of Velasco was fought in June 1832 in the growing friction between Texian settlers and Mexican authority; and here, in May 1836, peace treaties were signed with the captured General Santa Anna after the Texas Revolution. The Lively's landing opened a decade that would transform this shoreline into the doorstep of a new republic.
