Battles of the War Overview
Hostilities between the United States and Mexico began on April 25, 1846, and continued until September 14, 1847. During the course of the war, the United States and Mexico would engage in dozens of conflicts, together losing upwards of 38,000 soldiers (Only about 1,700 U.S. deaths were directly battle-related. The rest came from disease that raged in the U.S. camps).
In 1848, the U.S.-Mexican War came to a dramatic close in Mexico City with the entry of U.S. troops.
