Battle of Churubusco
On 6 September 1847, Scott ended the armistice following the Battle of Churubusco as negotiations broke down, as it became clear that Antonio López de Santa Anna was preparing to resume fighting. On 7 September, a large number of Mexican horsemen were observed around a group of low, massive stone buildings known as El Molino del Rey or King's Mill. Spread across the distance of this point, they were about west of the Castle at Chapultepec, which itself was about 2 mi (3 km) from the gates of Mexico City. A large grove of trees separated the mill from the castle, while the castle's batteries covered the area.
