Answer: TRUE
Explanation: The siege of Bexar (San Antonio) became the first major campaign of the Texas Revolution. From October until early December 1835 an army of Texan volunteers laid siege to a Mexican army in San Antonio de Béxar. After a Texas force drove off Mexican troops at Gonzales on October 2, the Texan army grew to 300 men and elected Stephen F. Austin commander to bring unity out of discord. The Texans advanced on October 12 toward San Antonio, where Gen. Martín Perfecto de Cos recently had concentrated Mexican forces numbering 650 men. Cos fortified the town plazas west of the San Antonio River and the Alamo, a former mission east of the stream.
By the time the Texans camped along Salado Creek east of San Antonio in mid-October their numbers had grown to over 400 men, including James Bowie and Juan N. Seguín, who brought with him a company of Mexican Texans. Bowie and James W. Fannin, Jr., led an advance to the missions below San Antonio in late October, while Cos brought in 100 reinforcement men. On October 25 the democratic Texans conducted a debate over strategy. Sam Houston, who had come from the Consultation government, urged delay for training and for cannons to bombard the fortifications. Austin and others won support to continue efforts at capturing San Antonio.
From San Francisco de la Espada Mission on October 27, Austin sent Bowie and Fannin forward to Nuestra Señora de la Purísima Concepción de Acuña Mission with ninety men to locate a position nearer the town for the army. There on the foggy morning of the twenty-eighth Cos sent Col. Domingo de Ugartechea with 275 men to attack the advance force. The Texans drove off the assault from a position along the bank of the San Antonio River, inflicting over fifty casualties and capturing one cannon. Austin arrived after the battle of Concepción to urge an attack on San Antonio but found little support among his officers.
