The city itself followed two years later. When the Treaty of Guadalupe Hidalgo ended the war in 1848 and set the Rio Grande as the border, a merchant named Charles Stillman — a Connecticut Yankee who had been doing business across the river in Matamoros — bought up land beside the fort, laid out streets, and founded the town of Brownsville. It became the seat of the new Cameron County the next year. Stillman's riverboats worked the Rio Grande trade, and the settlement around the fort grew quickly into the commercial heart of the lower valley, a port and crossing point between two nations.
Brownsville holds a second, stranger distinction. Where the Mexican-American War opened just outside town, the Civil War effectively closed there. On May 13, 1865 — more than a month after the surrender at Appomattox — Confederate and Union forces met at Palmito Ranch a few miles east of the city in what is remembered as the last land battle of the war. So Brownsville can claim both ends of the story: the first major battle of one war and the last land battle of another, bookends fought within sight of the same river.
Why People Visit Brownsville
Visitors come to Brownsville for a mix found nowhere else: battlefield and border history, world-class birding among the resacas and palms, and a living binational culture of music, food, and festival. The Gulf beaches are a short drive, Matamoros a few blocks across the river, and the Charro Days fiesta turns late winter into a two-nation celebration. Equal parts Texas heritage and Rio Grande Valley warmth, Brownsville rewards anyone drawn to the place where the river meets the Gulf.
