As part of the broader Mexican–American War, U.S. General Zachary Taylor led the Army of Occupation southward into Mexican territory. Monterrey, a fortified city defended by General Pedro de Ampudia and the Mexican Army of the North, stood as a strategic objective in northern Mexico.
From September 21 to 24, 1846, U.S. forces engaged Mexican defenders in intense urban combat throughout Monterrey. The fighting caused heavy casualties on both sides before the two armies began negotiations to end the immediate conflict.
The battle concluded with a two-month armistice agreement. Mexican forces were permitted an orderly evacuation in exchange for surrendering the city, giving U.S. forces control of Monterrey and advancing American strategic objectives in northern Mexico.
