Cortina retained control over Brownsville until 30 September 1859, when he evacuated the town at the urging of influential residents of Matamoros. The following days, the townsfolk of Brownsville formed a twenty-man group in order to fight Cortina, called ""the Brownsville Tigers"". In November, the Brownsville Tigers learned that Cortina was at his mother's ranch in the nearby town of Santa Rita, five miles west of Brownsville. They immediately launched an attack, only to be sent into retreat in disarray by Cortina's forces.
