What battle ended the Mexican-American War and led to the establishment of the Republic of Texas?

The Battle of San Jacinto was a pivotal conflict that occurred on April 21, 1836, during the Texas Revolution. This battle marked a decisive victory for Texian forces led by General Sam Houston over the Mexican army commanded by General Santa Anna. The outcomes of the Battle of San Jacinto were significant, as they not only secured Texian independence from Mexico but also laid the groundwork for the Republic of Texas. The swift victory at San Jacinto effectively caught the Mexican forces by surprise, leading to the capture of Santa Anna and ultimately forcing his recognition of Texian independence.

Understanding this context is crucial, as the other battles listed do not pertain to the end of the Mexican-American War or the establishment of the Republic of Texas. The Battle of the Alamo, while a symbol of resistance, was actually a defeat for Texian forces. The Battle of Veracruz was part of the Mexican-American War, but it did not result in Texas' independence. The Battle of Buena Vista also occurred during that same war, focusing more on U.S. military engagements with Mexico rather than the Texas Revolution. Thus, the Battle of San Jacinto stands out as the critical event leading to Texas achieving its independence and forming its republic.
