At this site north of Brownsville
near the Intersection of FM 1847 and FM 511, an artillery duel opened the U.S. Mexican War in 1846. Cannon under the command of General Zachary Taylor proved superior to that of the Mexicans. The site was dedicated as a national historic site in 1993 on the 147th anniversary of the battle. The mandate that created the site specified that exhibits must cover the war from the standpoints of both countries. The visitors center showcases many artifacts and historical information from the war and includes a bookstore.
