The expedition of José Antonio Mexía during the summer of 1832 had two purposes: the carrying into execution of the Plan of Vera Cruz against Anastacio Bustamante and absolutism in Mexico, and the preservation of Texas in the Mexican union. Mexía sailed from Tampico on June 22, 1832, with 300 soldiers on five ships. Soto la Marina appeared too strongly fortified for him to attack, so he proceeded against Matamoros, or Brazos de Santiago, where he anchored on June 26, 1832. Two units of troops at Matamoros declared for Antonio López de Santa Anna, and Mexía entered the city without resistance on June 29. On July 6 he and José Mariano Guerra, local commander, drew up articles of agreement. Mexía left Matamoros on July 14, 1832, on his way to Texas, after being joined by Stephen F. Austin, who was on his way home from a meeting of the legislature of Coahuila and Texas. Mexía had four hundred troops when he reached the mouth of the Brazos River on July 16. He was hospitably received at Brazoria, where on July 17 a meeting of the townspeople explained to him the causes of the Anahuac Disturbances and the battle of Velasco and asserted that the Turtle Bayou Resolutions were in conformity with the Plan of Vera Cruz. All matters of consequence were satisfactorily settled during his six-day stay at Brazoria. When Mexía reached Galveston on July 24, he met the vessels bearing the troops from Anahuac who had also embraced Santa Anna's cause. Mexía decided that Texas affairs were progressing satisfactorily for Santa Anna and returned to Tampico, where he arrived on July 28.
