verged northeastwardly and eastwardly towards the city. The northernmost of these entered Mexico by the garita of San Cosmé, while the other reached it by that of Belen near the citadel.
In attacking Chapultepec, it was important to consider the value of the Molino del Rey or King's Mill, and Casa Mata, both of which, as we noticed, lie on rising ground within the works designed to protect Chapultepec. Upon examination it will be found that the Molino del Rey, or King's Mill, bears the relation of a very strong western outwork both to the castle of Chapultepec and its approaches by the inclined plain which serves to ascend its summit. As the Molino del Rey is commanded and defended by the castle, so it reciprocally, commands and defends the only good approach to the latter.[1] As long as the Molino was held by the Mexicans, it would of course, form an important stronghold easily reached from the city around the rear of Chapultepec; so that if Scott attacked the castle and hill from the south, where the road that ascends it commenced, he would be in danger of an attack on his left flank from the Mexicans in the defences at Molino and Casa Mata.
If the King's Mill fell, the result to the enemy would be that, in addition to the loss of an important outwork and the consequent weakening of the main work, its occupants or defenders would be driven from a high position above the roads and fields into the low grounds at the base of Chapultepec, which were completely commanded from the Molino, and thus the Mexicans would be unable to prevent the American siege pieces from taking up the most favorable position for battering the castle. It was important, therefore, not only that the foundry should be destroyed, but, in a stratagetic view, it was almost indispensable in relation to future operations that the position should be taken. It is undeniable, as following events showed, that the Mexicans regarded it as one of their formidable military points. The capture of Chapultepec and the destruction of the post at Molino del Rey were, accordingly, determined on as preliminary to the final assault upon the city.
As soon as the armistice was terminated bold reconnoissances were made by our engineers in the direction of Chapultepec and the Molino or King's Mill and Casa Mata. On the 7th of September Santa Anna's answer to Scott's despatch was received, and on the same day the Commander-in-Chief and General Worth examined the enemy's formidable dispositions near and around the castle-
