The Battle for Mexico City was a series of engagements from September 8 to September 15, 1847, during the Mexican–American War. These battles culminated in the American victory and occupation of Mexico City, marking a decisive moment in the conflict. This article explores the key battles and strategies that led to this outcome.
The Road to Mexico City
The major objective of American operations in central Mexico was the capture of Mexico City. After securing the port of Veracruz
in March 1847, General Winfield Scott moved inland, defeating Mexican forces at the Battle of Cerro Gordo. By August, Scott's army was within striking distance of Mexico City, having routed the Mexicans at the Battle of Churubusco.
The fight for Mexico City began on September 8 with the Battle of Molino del Rey. General Scott believed a cannon foundry was located at the King's Mill, just outside the city. Despite heavy casualties, the U.S. forces drove the Mexicans from the mill, separating them from the forces at Chapultepec.
The Assault on Chapultepec
The main assault on Mexico City occurred on September 12, with Chapultepec Castle serving as a key defensive position. Scott preceded the infantry assault with an artillery barrage, and on September 13, the 4th Division, led by John A. Quitman, spearheaded the attack, capturing the castle.
The defense of Chapultepec included the cadets known as Los Niños Héroes, who became legendary for their bravery. Despite their efforts, the Mexican forces retreated within the city, paving the way for the final assault.
The Fall of Mexico City
Quitman's Division advanced towards the Belén Gate, while Worth's Division targeted the San Cosme Gate. Both gates fell after intense fighting, and the Mexicans withdrew into the city. Santa Anna's release of prisoners led to rooftop skirmishes, but Worth managed to restore order.
On September 15, Quitman's Division formally entered the city, marking the American occupation. General Scott appointed Quitman as military governor, solidifying U.S. control. The Battle for Mexico City was a decisive victory, ending the war and leading to the Treaty of Guadalupe Hidalgo.
The series of engagements demonstrated the strategic importance of capturing Mexico City, ultimately shaping the outcome of the Mexican–American War. The fall of the city marked a turning point, leading to the end of hostilities and the expansion of U.S. territory.
