For those that are unaware in 1829 the Spanish empire attempted to reconquer Mexico, and this culminated in the Battle of Tampico. Which saw Mexican forces led by General Santa Anna against the Spanish forces led by Isidro Barradas. The battle ended with a clear Mexican victory and this permanently ended Spanish attempts to return Mexico to the Spanish Empire.
However, what happened if Spaniards were successful in the battle? Would a victory here be as conclusive for the Spanish forces as it was to the Mexican forces IOTL or would further rebellion / insurrection be mounted against the Spanish forces? Furthermore, working under the assumption that the Spaniards re-establish control over Mexico, how does that impact upon their relationship with the expanding American republic? Could it lead to an earlier Spanish - American war?
