Battle of Buena Vista - Aftermath His last assault defeated, Santa Anna held a council of war as night and heavy rains descended. Having lost 594 dead, 1,039 wounded, 1,800 missing, and 294 captured, he elected to retreat south. Taylor, whose position remained precarious, lost 267 dead, 456 wounded, and 23 missing. The final major battle in northeastern Mexico, the stunning American victory carried Taylor to the presidency the following year. On a similar note, the military reputation won by Davis aided him in becoming the future president of the Confederacy during the
Civil War. Returning to Mexico City, Santa Anna led a campaign against Scott in which he was roundly defeated.
