On August 2, 1832, Texas settlers refused an order to surrender their arms to José de las Piedras, commander of the Mexican battalion at Nacogdoches. He evacuated his soldiers and headed for San Antonio, after the settlers captured the Old Stone Fort and other locations. A detachment of mounted Texans, including James Bowie, caught them the next day after a running fight along the Angelina River. The Battle of Nacogdoches is called the opening gun of the Texas Revolution.
