The Story

Founded in 1846 and named for Thomas W. Gilmer — U.S. Secretary of the Navy and a fervent champion of Texas annexation — this East Texas town came of age just as Texas joined the Union. During the Civil War it served as a supply, training, production, and educational center for the Confederacy, and later thrived as a hub of farming, lumbering, and oil. Today it is perhaps best known for its long-running Yamboree sweet-potato festival.

Why it matters

Its name and its Civil War role bind a single East Texas town to the national dramas of annexation and the Confederacy.

The story behind this marker

AI context

The era

Gilmer was founded in 1846, a pivotal year for Texas. The Republic of Texas had just joined the United States, ending nearly a decade of independence. New counties were being organized across the eastern timberlands, where settlers from the older Southern states were clearing land for farms.

East Texas looked more like the Deep South than like the ranch country of the West. Its piney woods and fertile soils drew families who brought Southern farming traditions with them, including cotton and slavery. Gilmer became the seat of the newly created Upshur County and grew up as a trading and government center for the surrounding farms.

Fifteen years later the nation split apart. Texas seceded in 1861 and joined the Confederacy, and towns deep in the interior, far from the main battlefields, became important behind the lines as sources of supplies, soldiers and support.

People & events

The town's name ties it directly to the fight over annexation. Thomas W. Gilmer was a Virginian who served as U.S. Secretary of the Navy and argued forcefully for bringing Texas into the Union. In the early 1840s annexation was one of the most bitterly debated questions in American politics, and he stood firmly on the side of bringing Texas in.

He did not live to see it happen. Gilmer was killed in 1844, only days into his term as Navy Secretary, when a large gun exploded aboard the warship USS Princeton during a demonstration cruise on the Potomac River. Several other officials died in the same disaster, including Secretary of State Abel P. Upshur, who is the namesake of the county around this town. Two men killed by one explosion gave their names to this county and its seat.

During the Civil War, Gilmer served the Confederacy as a supply, training, production and educational center, a home-front hub supporting the war far from the front lines. Afterward, the town's economy moved through the region's major industries: farming, lumber from the surrounding forests, and later oil.

Today Gilmer is best known for its famous annual Yamboree, a festival celebrating the East Texas sweet potato. It shows how a farm crop can become the center of a town's pride and identity.

Its place in the American story

Gilmer's name recalls a time when adding Texas to the Union was at the heart of American politics. Annexation fed the debate over the expansion of slavery, helped provoke war with Mexico, and moved the country toward its huge westward growth in the 1840s. By naming a town after one of annexation's champions, Texans honored the national figures who had pushed for their entry.

The USS Princeton disaster was a national shock in its own day, one of the deadliest single moments for high federal officials in American history. The fact that both Upshur County and Gilmer carry the names of its victims is a lasting local memorial to that event.

Gilmer's Civil War role reflects a part of the Confederate story that often gets overlooked. Wars are fought on the front lines, but they are supplied, staffed and sustained in towns like this one, where farms, workshops and schools were put to work for the war.

If you visit

Gilmer is a classic East Texas county seat, set among piney woods and rolling farmland. A walk around the town center gives you a sense of the courthouse-town layout that anchored rural Texas life for generations.

If you can plan around it, try to visit during the Yamboree. The festival is the town's signature event and a lively look at small-town East Texas traditions. Check local listings for dates before you go.

Gilmer fits nicely into a road trip through the East Texas piney woods. The region's forests, lakes and historic small towns reward slow backroad travel, and here a single name on a marker connects you to annexation, a naval disaster and the Civil War.

Little Mound Baptist Church and Cemetery

Gilmer, TX

Burials on this steep rise called "Little Mound" may reach back to the late 1860s, before residents of the pioneer village of Calloway organized Little Mount Baptist Church in 1878 in a former Union church and schoolhouse. Over the decades the congregation rebuilt three times, thriftily reusing the same lumber from one meetinghouse to the next. Among those buried here is Emma Sansom Johnson, remembered as a Confederate heroine who as a sixteen-year-old guided General Nathan Bedford Forrest's troops across a river in her native Alabama before later settling in Texas.

County Line Cemetery

Harleton, TX

In the years around the Civil War, settlers drawn from North Carolina, Mississippi, and Georgia gathered near the Harrison–Upshur county line to form the Crossroads community, founding a Baptist church and this cemetery on land given by Dr. T.B. Burford. The earliest marked grave belongs to Eli Henderson McCoy, who came from North Carolina in 1859, served in the Confederate Army, and died in 1863. Tombstones bearing military and fraternal emblems—and two rare stone cairns—record the lives of the families who built the settlement.

Pitts Family Cemetery

Pittsburg, TX

This burying ground was begun by William Harrison Pitts, the founder of Pittsburg, with the 1862 grave of his wife Sarah. The Pitts family had left their Georgia plantations to reestablish themselves on the Texas frontier in the mid-nineteenth century, and the plot soon held a Confederate corporal, Pitts's mother, and several of his siblings. Their arrival helped shape the young community of Camp County.
