Although Urrea reported that 42 Texians were killed , early 20th century historians generally only list 12 Texians as killed . Tejano involvement in the revolution had been notably absent from textbooks until the 1970s , so it is likely that historians were not including the '' Tejanos '' under Benavides . Six Texians were taken prisoner . In defiance of the Tornel Decree , Urrea spared those who surrendered and sent them to a prison in Matamoros . Reports indicated that Urrea offered clemency after the intervention of Francita Alavez , the mistress of one of Urrea 's soldiers . Six Texians escaped . Five of these joined Fannin 's garrison at Goliad and were later killed in the Goliad massacre . No reports of Mexican losses have been found , although at least one Mexican soldier is thought to have died . After the battle , Mexican soldiers rounded up the horses that the Texians had been herding and kept them . The battle marked the end of the Matamoros Expedition . Although it occurred on the same day that Texas declared independence , Grant and his men did not know that they were fighting for the new Republic of Texas
