Palo Alto Battlefield National Historic Site


Palo Alto Battlefield National Historic Site in Texas, the only site in the entire National Park System dedicated to the Mexican-American War, presents both nations' perspectives on the battle over a boundary. In 1845, when Texas entered the Union, it brought with it a boundary dispute with Mexico. In May 1846, President James K. Polk declared war, and the first battle of the Mexican-American War was fought on the plains of Palo Alto.

Palo Alto Battlefield National Historic Site commemorates the
Mexican-American War.


General Zachary Taylor's troops met about 4,000 Mexican soldiers armed with dated cannons and ammunition. The cannonballs fired at the American troops traveled so slowly that U.S. soldiers simply side-stepped the incoming rounds. With the help of newly manufactured cannons that fired farther and faster than the Mexican arms, the United States Army pushed back the Mexican troops. This victory and others paved the way for U.S. invasion and occupation of the northeastern portion of Mexico, south of the Rio Grande.
