Palmito Ranch Battlefield, Historic site in Cameron County, United States.

Palmito Ranch Battlefield is a historic site along the Rio Grande in Cameron County, Texas, recognized as a National Historic Landmark. The land is flat and open, covered by grasslands and shallow marshes that have changed little since the Civil War era.

The last land battle of the American Civil War took place here on May 12 and 13, 1865, weeks after the Confederate surrender at Appomattox. Confederate forces won the engagement even though the war had already ended across most of the country.

The site remembers soldiers from both sides who fought in a clash that most history books barely mention. Markers on the ground give visitors today a concrete sense of the people involved and the events that unfolded here.

The site lies east of Brownsville at the junction of Palmito Hill Road and Boca Chica Highway, and the flat ground is easy to walk. There is almost no shade, so bring water and sun protection, especially during the warmer months.

The surrender at Appomattox had already been communicated to both commanders at Palmito, yet Confederate General Edmund Kirby Smith had rejected a proposal to surrender his Trans-Mississippi forces on those terms. He only surrendered officially on June 2, 1865, so the fight went ahead.
