September 21–24, 1846
A fierce four-day urban battle for the heavily fortified city of Monterrey in northeastern Mexico. Taylor divided his force, sending Worth's division to cut the western road while he attacked from the east. American soldiers fought house-to-house through the city's narrow streets, using picks and crowbars to break through walls rather than expose themselves in the open. After heavy casualties on both sides, Ampudia negotiated an eight-week armistice and withdrew his army — a decision that angered President Polk.
