Camp Belknap

Brownsville, Cameron County, Texas

Marker Inscription

In May 1846 when war was declared against Mexico, the U.S. Congress authorized the raising of 50,000 volunteer troops to supplement the regular U.S. Army. General Zachary Taylor was quickly inundated with volunteer soldiers arriving at Brazos Santiago, and was forced to place them in temporary encampments. Camp Belknap, located on this site, was established in the summer of 1846. The camp was located on a long narrow rise of land, measuring about 2 miles in length and one-half mile at its widest point. It was the first high ground encountered after leaving the Gulf Coast. Thought to be the largest encampment for volunteer soldiers, troop estimates total 7,000-8,000 men including several regiments from eight states. Soldiers suffered exposure to the elements, unsanitary living conditions, overcrowding, biting insects, thorny plants, and disease. Many died a premature death, often resulting in one two two funerals daily. No enemy attacks took place despite one false alarm. During August and September most of the volunteers were moved upriver either to camps nearer Matamoros, or further to Camargo. The camp was completely empty by December 1846.

The Story

When the United States declared war on Mexico in May 1846, thousands of volunteers poured into Brazos Santiago, and General Zachary Taylor established Camp Belknap here that summer to hold them. Spread across a narrow rise of high ground, it may have been the largest volunteer encampment of the war, sheltering an estimated 7,000 to 8,000 men. No enemy ever attacked, but exposure, disease, and squalor killed many before the troops moved upriver by year's end.

Why it matters

Camp Belknap reveals the deadly, unglamorous reality of mobilization in the Mexican-American War, where more soldiers fell to disease than to combat.

The story behind this marker

AI context

The era

In May 1846 the United States went to war with Mexico. The conflict grew out of the annexation of Texas and a dispute over where Texas ended: the United States claimed the Rio Grande as the border, while Mexico did not accept that claim. The first clashes took place in the Rio Grande delta near present-day Brownsville, and the war that followed would reshape the map of North America.

The regular U.S. Army of the day was small, far too small for a war of this size. So Congress authorized the raising of 50,000 volunteers. Enthusiasm ran high in many states, and men signed up by the thousands, many with little training and no experience of military life.

Getting those men to the front was a problem in itself. Volunteers came by sea to the Texas coast and landed at Brazos Santiago, and the army needed somewhere to put them. Few people in 1846 understood how disease spreads, and crowding thousands of unseasoned men into rough camps in a hot, wet climate was a recipe for disaster.

People & events

General Zachary Taylor commanded the American forces on the lower Rio Grande. That spring, his army had already fought the war's first major battles nearby. Now he faced a different challenge: a flood of volunteer soldiers arriving at Brazos Santiago faster than they could be organized, supplied, or sent forward. He had no choice but to set up temporary camps.

Camp Belknap was established on this site in the summer of 1846. It stood on a long, narrow rise, about two miles long and half a mile across at its widest, the first high ground a traveler reached after leaving the Gulf Coast. It is thought to have been the largest volunteer encampment of the war, holding an estimated 7,000 to 8,000 men from regiments of eight states.

For those men, the enemy they met was not the Mexican army. They faced exposure to the weather, filthy and crowded conditions, biting insects, thorny brush, and disease. Many died young and far from home, and funerals came as often as once or twice a day. Only one false alarm broke the routine; no attack ever came. In August and September most of the volunteers moved upriver to camps nearer Matamoros or on to Camargo, and by December 1846 the camp was empty.

Its place in the American story

Disease killed far more American soldiers in the Mexican-American War than enemy fire did, and Camp Belknap shows how that happened. The war is usually remembered through its battles and generals, but for thousands of volunteers the real danger was sickness in overcrowded, unsanitary camps. Places like this are where most of that toll was paid.

The war itself changed the nation. When it ended, Mexico gave up a vast territory in the Southwest and the Rio Grande was confirmed as the Texas border. The fierce arguments over whether slavery would spread into the new land helped set the country on the road to the Civil War. Zachary Taylor, whose name is on this marker, rode his wartime fame all the way to the presidency.

Camp Belknap also marks a turning point in the way America went to war. Relying on huge numbers of short-term volunteers, and learning at great cost how to house and supply them, was a lesson the country would face again in later wars.

If you visit

Stand here and notice the land itself. The marker describes a long, narrow rise, the first high ground inland from the coast, and that slight elevation is the whole reason the camp was put here. In the flat, low country of the Rio Grande delta, a little height meant drier footing.

Take a moment to picture the scene in the summer of 1846: thousands of tents crowded along the ridge, heat and insects, and funerals as often as once or twice a day. Nothing visible remains of the camp, and that is part of its story. It was always meant to be temporary.

Camp Belknap fits naturally into a tour of the Brownsville area's Mexican-American War sites, where the war's opening battles were fought. Taken together, they tell both halves of the story: the battles that were fought and the long, deadly wait in camps like this one.

These Palmetto Pilings

Brownsville, TX

These weathered pilings mark two separate military supply roads a generation apart. The cypress piles are remnants of a floating bridge Gen. Zachary Taylor threw across Boca Chica Inlet in 1846 during the Mexican-American War; the palmetto pilings are what remains of a railroad crossing begun by Gen. Francis Herron in 1864 and finished by Gen. Philip Sheridan in 1865 to move Union supplies at the close of the Civil War.

Site of Fort Polk

Port Isabel, TX

A Mexican ranching village once stood on this point, settled in the 1700s and abandoned before the United States declared war on Mexico in 1846. That March, General Zachary Taylor's forces occupied the site and built a supply depot to receive shipments from New Orleans, a six-sided earthwork named Fort Polk for the president. The fort was abandoned in 1850, but the settlement it drew grew into Port Isabel, with traces of the earthworks visible into the 1920s.

Port Isabel (Old Point Isabel)

Port Isabel, TX

About 1828 this bluff on the lower Rio Grande held Don Rafael Garcia's ranch, "El Fronton de Santa Ysabel," and by 1844 a Mexican customs station moved here after storms destroyed nearby coastal villages. Following the Mexican War, the U.S. established the Point Isabel post office in 1849, and goods landed here were freighted inland to Matamoros. In 1873 a railroad finally linked the port to Brownsville, serving until a deepwater channel to Brownsville replaced it in 1933.

Port of Matamoros

Port Isabel, TX

Established in 1824, the Port of Matamoros channeled goods shipped from New Orleans and other U.S. ports overland to the towns of northern Mexico, guarded by a Mexican garrison and naval vessel. During and after the Texas Revolution it saw repeated naval clashes between the U.S. and Mexico in 1836–37. Jurisdiction was only settled in 1846, when General Zachary Taylor's forces occupied the area at the opening of the Mexican War.
