Resaca de la Palma Battlefield, Mexican-American War battlefield in Brownsville, United States

Resaca de la Palma Battlefield is a natural area in Brownsville with walking trails and interpretive signs across former combat grounds where Mexican and American forces clashed. The landscape features sections of the original resaca, a former river channel that influenced military positions during the engagement.

After the Battle of Palo Alto on May 8, 1846, General Mariano Arista's Mexican forces retreated to this bend of the Resaca de la Palma and dug in on the north bank amid dense chaparral, placing artillery near a bridge crossing. On May 9, Zachary Taylor's pursuing Americans assaulted the position, drove the Mexicans across the water and captured Arista's command post, nearly taking the general himself. A 50-acre fragment was designated a National Historic Landmark in 1960; the National Park Service acquired a 34.4-acre section from the Brownsville Community Foundation in August 2011.

The site preserves memories of the Mexican-American War through educational programs and guided tours that explain military tactics and troop positions. Visitors can see how the landscape shaped the choices commanders made during the battle.

The grounds are accessible through marked trails with parking available for visitors. Walking the site is straightforward, and information displays throughout help you understand the battle positions.

The name resaca comes from a Spanish word for an old river channel, and you can still see how this terrain shaped military decisions on that day. The preserved waterways were crucial to how troops positioned and moved during the engagement.
