Spain set up Missions to convert Native-American to Christians. They had Presidios or Garrisons defending them from Native-Americans. TJe Mission Persidio-System was a complete failiure.
The mission and presidio were typically located close together, with the presidio serving as a military fort to protect the mission. They were usually within a few miles of each other for strategic purposes and ease of communication and defense.
The battle of Coleto, the culmination of the Goliad Campaign of 1836, occurred near Coleto Creek in Goliad County on March 19 and 20, 1836. Colonel Fannin, commanding, was ordered to abandon the persidio and mission complex he had been defending at Goliad and was on his way to Victoria when overtaken by a large number of Mexican soldiers under command of General Jose de Urrea. Surrounded on the prairie, and greatly outnumbered, these relatively untrained men fought valiantly the afternoon of the 19th, and surrendered on the 20th. The more than 300 "Texicans" under command of Colonel Fannin surrendered at Coleto Creekonly after being promised in writing by General Urrea personally that they would be treated humanly, as prisoners of war.
