History & Significance

Battle of San Antonio Mexico was a Mexican-American War engagement fought in Mexico, 1847. It was a United States victory.

The Battle for Mexico City refers to the series of engagements from September 8 to September 15, 1847, in the general vicinity of Mexico City during the Mexican-American War. Included are major actions at the battles of Molino del Rey and Chapultepec, culminating with the fall of Mexico City. The U.S. Army under Winfield Scott won a major victory that ended the war.

The major objective of American operations in central Mexico had been the capture of Mexico City. After capturing the port of Veracruz in March, General Winfield Scott was able to secure a base and move inland and defeat a large Mexican force at the Battle of Cerro Gordo. After routing the Mexicans at the Battle of Churubusco, Scott's army was less than eight kilometers (five miles) away from its objective of Mexico City.

On September 8, the fight for Mexico City began. General Scott believed that a cannon foundry was located at the Molino del Rey, known as the King's Mill, located just over three kilometers (two miles) outside the city. Scott sent the 1st Division under William J. Worth to seize and destroy the foundry. Worth wished to include Chapultepec Castle in his attack, and when Scott refused, a bitter rivalry began between Scott and Worth. In the ensuing battle, both sides suffered heavy casualties, and Worth drove the Mexicans from the mill, separating them from the forces at Chapultepec. The battle produced no significant military gains for the U.S.

The main assault on the city came a few days later on September 12. Mexico City was guarded in part by Chapultepec Castle, which was being used as a military academy. Scott preceded an infantry assault with an all day artillery barrage on September 12. The next day, September 13, the 4th Division, under John A. Quitman, spearheaded the attack against Chapultepec and carried the castle. Future Confederate generals George E. Pickett and James Longstreet participated in the attack. Serving in the Mexican defense were the cadets later immortalized as Los Niños Héroes (the "Boy Heroes"). The Mexican forces fell back from Chapultepec and retreated within the city.

Quitman's Division made its way down the Belén Causeway towards the Belén Gate, defended by General Terres & Colonel Garay with the 2d Mexico Activos (200 men) and 3 guns (1-12 lbs. & 2-8 lbs.), while Worth's Division further to the north made its way up La Verónica Causeway towards the San Cosme Gate, defended by General Rangel's Infantry Brigade (Granaderos Battalion (Adj. A. Manero), 1st Light (Comdte. L. Marquez), part 3d Light (Lt.Col. M.M. Echeagaray) and parts of Matamoros, Morelia and Santa Ana Battalions (Col. J.V. Gonzalez) with 3 guns (1-12 lb, 1-8 lb. and 1 howitzer 24 lbs). Quitman was merely supposed to make a feint towards the city, but he pushed forward his whole division and broke through the defenses. Santa Anna arrived at the Belén Gate in a fury and relieved the front commander. Worth's Division in the meantime had a slow start against the Mexicans after beating off a Mexican cavalry attack. When he reached San Cosme, he found its defenses ill-prepared, but the Mexicans defending it fought well before falling back. Ulysses S. Grant found his way into the action along the causeway on Worth's front and helped in hoisting a cannon into the belltower of a nearby church. From this spot Grant fired into the defenders below. When the fighting subsided on all fronts, both gates had fallen and the Mexicans had withdrawn into the city. Other gates defended were: San Antonio by General M. Martínez (3d & 4th Ligero & 11th Line with 10 guns) before withdrawing; Nino Perdido by the National Guards and 2 guns; and San Låzaro, Guadalupe and Villejo, which were defended by small infantry detachments. Other forces were stationed at la Piedad (1st & 2d Mexico Activos and Guanajunto Battalions), the Insurgente bridge (Gen. Arguelles : Invalidos and Lagos Battalion) and in the rear of these (Gen. Ramirez with 2d Ligero and various pickets) before withdrawing to the Citadel.
