Final answer:
The Battle of Buena Vista resulted in an American victory, despite General Zachary Taylor's forces being heavily outnumbered by Mexican General Santa Anna's army.
Step-by-step explanation:
During the Battle of Buena Vista, also known as Las Angostura, which took place on February 22-23, 1847, the American army, commanded by General Zachary Taylor, was significantly outnumbered by the troops of Mexican General Antonio Lopez de Santa Anna. Despite the numerical disadvantage, the Americans were able to withstand repeated assaults by the Mexican forces. Taylor's effective use of artillery and the rugged terrain helped to repel Santa Anna's attacks. At the end of the second day of fighting, Mexican forces withdrew, considering the losses too great to continue the assault. The battle was a tactical victory for the American forces as they managed to hold their ground against an army nearly three times their size.
