12 SEP--This Day in US Military History

1847 – The Battle of Chapultepec was a United States victory over Mexican forces holding Chapultepec Castle west of Mexico City during the Mexican-American War.

The Americans began an artillery barrage against Chapultepec at dawn. It was halted at dark and resumed at first light the next day. At 8 AM, the bombardment was halted and Winfield Scott ordered the infantry attack. There were three assault columns. On the left were the 11th and 14th Infantry under Colonel William Trousdale moving east along the Anzures aqueduct, in the center were four companies of the Voltigeur regiment under Colonel Timothy Patrick Andrews along with the 9th and 15th Infantry moving through the swamp and western edge of the grove, and on the right were the remaining four Voltigeur companies under Lieutenant Colonel Joseph E. Johnston.
Pillow was quickly hit in the foot and called for reinforcements, which came from John A. Quitman’s division but the attack faltered when fired upon by the Moelia Battalion battery. Andrews’s column cleared the grove of Mexican troops and linked up with Johnston. Yet, the attack by the 9th and 15th Infantry stalled waiting for scaling ladders, and Col. Truman B. Ransom was killed. Quitman sent Persifor Smith’s brigade to his right and brought in James Shields, plus the New York and 2d Pennsylvania Regiments into the assault. At the same time, Newman S. Clarke’s brigade arrived on the western slope, as did the scaling ladders. The Voltigeurs soon planted their flag on the parapet.
By 9 AM, General Bravo surrendered to the New York Regiment and the American flag flew over the castle. Santa Anna watched the Americans take Chapultepec while an aide exclaimed “let the Mexican flag never be touched by a foreign enemy”. He also exclaimed, “I believe if we were to plant our batteries in Hell the damned Yankees would take them from us.”
