Following the Battle of Chapultepec, Santa Anna withdrew his forces from Mexico City, leading a portion in an attempt to take Puebla and cut off Winfield Scott's supply route from Veracruz. The siege of Puebla began the same day Mexico City fell to Scott and lasted for 28 days before a relief force fought its way into the city.
