Editing Domingo Ugartechea (section)

===Siege of San Antonio===

During the [[siege of Béxar]], [[Stephen F. Austin]] conducted the Texan forces from the outskirts of the town, while Ugartechea at first remained with the Mexican forces in town. A unit of his cavalry engaged in reconnoitering around [[Cibolo Creek]] in mid-October. He then led a body of 275 infantry with two cannons from the town on the morning of  October 28, precipitating the [[Battle of Concepción]]. Colonel Ugartechea commanded a unit of cavalry that slipped through the siege forces on November 12 and made its way in about ten days to the [[Rio Grande|Rio Grande (Río Bravo)]] to seek reinforcements. On November 26 he guided a force of 454 conscripts and 173 veteran troops from Laredo to relieve the centralist army under Cos at Bexar. Their arrival on December 8, actually increased the burden of supply on the centralist army and helped to precipitate its surrender on December 9, to the Texans.
