Wm. B. Middleton

🏛️The era

In the early 1840s Texas was an independent nation, the Republic of Texas, and an uneasy one. Mexico had never accepted the loss of its former province after the revolution of 1836, and the border along the Rio Grande was disputed and dangerous. In 1842 Mexican forces raided Texas twice and briefly occupied San Antonio, and many Texans demanded revenge.

That anger produced an expedition to the southwest. Most of the force eventually turned back, but several hundred men went on without official approval. In December 1842 they crossed the Rio Grande and attacked the Mexican town of Mier. That was the beginning of the Mier Expedition, one of the most famous and tragic episodes of the Republic years.

Far to the northeast lay the forests and prairies of what would become Leon County, then still frontier land being settled by families moving in from the older American states. Once Texas joined the United States in 1845, counties like Leon were organized, and men who had lived through the Republic's struggles became their first officials.

👥People & events

William B. Middleton was born in Illinois in 1819, one of many young Americans drawn to Texas in its early years. Barely into his twenties, he joined the men who crossed into Mexico in 1842. The fight at Mier went badly for the Texans. Outnumbered and running low on supplies, they surrendered to the Mexican army.

What followed is the part Texans remembered for generations. The prisoners were marched deep into Mexico. A group of them broke out, but most were recaptured in the harsh country beyond. As punishment, Mexican authorities ordered one in ten of the recaptured men executed, chosen by drawing beans from a jar. Whoever drew a black bean was shot. Survivors were held in Mexican prisons until most were released in 1844.

Not everyone survived that long. The marker also remembers Beoni Middleton, who died in prison in Mexico as a Mier captive. The inscription does not say how he was related to William, but sharing a name and a memorial suggests the expedition left a lasting mark on the Middleton family.

William came home and built a life. He became the first sheriff of Leon County, the man responsible for law and order in a newly organized frontier county. He married Mary J. Potts, born in 1823, who died in 1874. William died in 1877, his life having run from the Republic's riskiest adventure to the everyday business of governing a Texas county.

🇺🇸Its place in the American story

The Mier Expedition was one episode in a long, bitter quarrel between Texas and Mexico over borders and sovereignty. That quarrel did not end with the Republic. After the United States annexed Texas in 1845, the same dispute over the Rio Grande border helped set off the U.S.–Mexican War of 1846–1848, which ended with Mexico giving up a vast stretch of the present-day American Southwest.

In that sense, a sheriff buried in a small East Texas community is tied to one of the largest changes in the map of North America. Men like Middleton lived through the violence that came before that war and then helped bring American-style local government to the land Texas had claimed.

His story is also a reminder of how close the frontier era is. A man born the year after Illinois became a state lived to see Texas through independence, annexation, the Civil War and Reconstruction. Early county sheriffs did that change on the ground, making a raw frontier into an organized community.

🧭If you visit

Leona is a small community in the rolling, wooded country of Leon County, about midway between Dallas and Houston. This is a quiet stop. Expect a peaceful rural setting rather than a visitor center, and take a moment to read the names and dates on the marker slowly.

Pay attention to the dates. William Middleton was only about twenty-three during the Mier Expedition, and many of his fellow prisoners were just as young. Remembering Beoni Middleton on the same memorial says a great deal about how deep that ordeal ran in Texas families.

If you're following the story of the Republic of Texas, this marker makes a meaningful detour on a drive between the state's big cities. It connects the high drama of the Mier Expedition to the slower work of settling and governing new counties, which is a side of frontier history that's easy to overlook.
