This is an 1847 Edmund Hardcastle map of the actions of General William Jenkins Worth's division during the Battle of Churubusco which took place near the end of the Mexican-American War. Oriented towards the east, the map depicts the battlefield from the bridge crossing the Churubusco River to south of the Hacienda San Antonio, one of the key positions during the battle, and focuses on the road between Churubusco and San Antonio. During the battle, General Worth's First Division was tasked with two critical objectives: first, to drive the Mexican forces defending San Antonio out of their stronghold, and, once that was accomplished, to attack Santa Anna's troops at the bridgehead crossing the Churubusco River. Hardcastle's map effectively traces the maneuvers involved in both objectives, illustrating how two of Worth's brigades moved off the causeway leading into San Antonio in an effort to cut off the Mexican troops stationed there. However, Santa Anna's forces retreated before they could be surrounded, and set up a new position at the tete-de-pont on the south side of the Churubusco River. Here, Worth's troops attached from multiple sides and eventually drove the Mexico forces across the bridge and into a full retreat towards Mexico City.
This map was drawn by Lieutenant Edmund La Fayette Hardcastle and published in a U.S. government report in 1847. Of the maps from this report that we have acquired, this appears to be one of the rarest, as it only appears in a handful of institutional collections and rarely appears on the private market.
