In March 1842, Mexican rebels tried to reinstate Mexican law in San Antonio, testing the strength of the Texas Republic. The threat was serious enough that the state capitol was moved to Houston to be more secure from Mexican invasion.
General Adrian Woll did capture San Antonio for Mexico in September 1842. Though badly outnumbered, a contingent of Texas Rangers and volunteers lured Woll’s men out of the city, where defenders lay in ambush in the rough terrain near Salado Creek. General Woll retreated toward the border with the Rangers in pursuit, and Texas’ independence was secured.
