While delegates at the Consultation (provisional government) debated the war's motives, Texians and a flood of volunteers from the United States defeated the small garrisons of Mexican soldiers by mid-December 1835.
[23] In response, President Anastasio Bustamante implemented the Laws of April 6, 1830, which, among other things, prohibited further immigration to Texas from the United States, increased taxes, and reiterated the ban on slavery.
In November 1833, the Mexican government attempted to address some of their concerns, repealing some sections of the law and granting the colonists further concessions,[32] including increased representation in the state legislature.
[40] Although prominent Tejano Juan Seguín raised a militia company to assist the governor, the Béxar ayuntamiento (city council) ordered him not to interfere,[41] and Viesca was arrested before he reached Texas.
[44] After several men staged a minor revolt against customs duties in Anahuac in June,[45] local leaders began calling for a public meeting to determine whether a majority of settlers favored independence, a return to federalism, or the status quo.
Although some leaders worried that Mexican officials would see this type of gathering as a step towards revolution, by the end of August most communities had agreed to send delegates to the Consultation, scheduled for October 15.
Without the northeastern province to act as a buffer, it was likely that United States influence would spread, and the Mexican territories of Nuevo Mexico and Alta California would be at risk of future American encroachment.
[49] In early September, Santa Anna ordered his brother-in-law, General Martín Perfecto de Cos, to lead 500 soldiers to Texas to quell any potential rebellion.
[39] After settlers escorted the group from town without the cannon, Ugartechea sent 100 dragoons with Lieutenant Francisco de Castañeda to demand compliance, with orders to avoid force if possible.
[64] The Texians established themselves in the presidio, under the command of Captain Philip Dimmitt, who immediately sent all the local Tejano volunteers to join Austin on the march to Béxar.
Austin sent a messenger to Cos giving the requirements the Texians would need to lay down their arms and "avoid the sad consequences of the Civil War which unfortunately threatens Texas".
[122] Leading federalists in Mexico, including former governor Viesca, Lorenzo de Zavala, and José Antonio Mexía, were advocating a plan to attack centralist troops in Matamoros.
[131] With his own authority in question following Smith's impeachment, Houston washed his hands of the army and journeyed to Nacogdoches to negotiate a treaty with Cherokee leaders.
[133] The council had neglected to provide specific instructions on how to structure the February vote for convention delegates, leaving it up to each municipality to determine how to balance the desires of the established residents against those of the volunteers newly arrived from the United States.
[141] The Mexican officers knew that the Brown Bess muskets they carried lacked the range of the Texian weapons, but Santa Anna was convinced that his superior planning would nonetheless result in an easy victory.
[155] Santa Anna and his commanders received timely intelligence on Texian troop locations, strengths, and plans, from a network of Tejano spies organized by de la Garza.
[148] When scouts brought word on February 23 that the Mexican advance guard was in sight, the unprepared Texians gathered what food they could find in town and fell back to the Alamo.
[168] The following day, a local woman, likely Bowie's relative Juana Navarro Alsbury, was rebuffed by Santa Anna when she attempted to negotiate a surrender for the Alamo defenders.
[201] Having learned from the fighting at Refugio, Urrea was determined that the Texians would not reach the cover of timber approximately 1.5 miles (2.4 km) ahead, along Coleto Creek.
A cavalry company led by Seguín and Salvador Flores were assigned as rear guard to evacuate the more isolated ranches and protect the civilians from attacks by Mexican troops or Indians.
Fear that Urrea's victories would position him as a political rival convinced Santa Anna to remain in Texas to personally oversee the final phase of the campaign.
[235][236] Government officials fled mere hours before Mexican troops arrived in Harrisburg, and Santa Anna sent Colonel Juan Almonte with 50 cavalry to intercept them in New Washington.
After loud protests from Seguín and Antonio Menchaca, the order was rescinded, provided the Tejanos wear a piece of cardboard in their hats to identify them as Texian soldiers.
[242][243] Over the protests of several of his officers, Santa Anna chose to make camp in a vulnerable location, a plain near the San Jacinto River, bordered by woods on one side, marsh and lake on another.
[264] Texians had won the battle due to mistakes made by Santa Anna, and Houston was well aware that his troops would have little hope of repeating their victory against Urrea or Filisola.
[268] In a letter to Filisola, who was now the senior Mexican official in Texas, Santa Anna wrote that "yesterday evening [we] had an unfortunate encounter" and ordered his troops to retreat to Béxar and await further instructions.
The Treaties of Velasco required that all Mexican troops retreat south of the Rio Grande and that all private property – code for slaves – be respected and restored.
[271] When Mexican authorities received word of Santa Anna's defeat at San Jacinto, flags across the country were lowered to half staff and draped in mourning.
[291] Voters overwhelmingly chose Houston the first president, ratified the constitution drawn up by the Convention of 1836, and approved a resolution to request annexation to the United States.
[132] Although the Texian interim governments had vowed to eventually compensate citizens for goods that were impressed during the war efforts, for the most part livestock and horses were not returned.
