Howdy historians - got a quick question for y'all. So the phrase "Dios y Tejas" (God and Texas) has been my little life's motto for years. To my understanding, when Stephen F Austin wrote to the Mexican government declaring texas' independence he ended the letter with the phrase "Dios y Tejas", instead of the traditionally accepted "Coahuila y Tejas", an action that was considered by many treasonous and helped spark our revolution. However, in all my research I have been able to find very little evidence to back the story up - was everything I taught a lie? Any insight y'all could offer would be greatly appreciated!

Edit: Ok, so I may have found the answer on my own. According to the Convention of 1833 Wikipedia page (a fountain of academic truth)

A cholera epidemic reached Mexico City within days of Austin's arrival, prompting Congress to adjourn before Austin could present the convention's resolutions. As he waited for the legislature to reconvene, Austin heard rumors that Texians were planning a third convention to unilaterally declare themselves a separate state. Although Austin was also frustrated at the lack of progress, he disapproved of this drastic proposal. In an attempt to quell the more radical groups in Texas, in October Austin sent a letter to the ayuntamiento in San Antonio de Béxar in which he proposed that all of the ayuntamientosshould jointly form a new state government. In what could be interpreted as an inflammatory gesture, Austin signed his letter "dios y Tejas" ("God and Texas") rather than the traditional Mexican closing "dios y libertad" ("God and liberty"). A few days after he had posted the letter, the immigration ban was repealed, assuaging one of the major Texian concerns. Austin had expected the letter to reach his friend Músquiz, who could be trusted to determine when or if it was appropriate to publicly disclose its contents. The letter arrived while Músquiz was out of town and was read by an unsympathetic ayuntamiento member. At this member's request, the ayuntamiento of San Antonio de Béxar forwarded the letter to state officials in Coahuila. The new governor, Francisco Vidaurri y Villaseñor, ordered Austin's arrest. Austin was arrested in December on suspicion of treason. He was imprisoned through all of 1834 and remained in Mexico City on bond until July 1835.
