At daybreak on the 13th the cannonade recommenced, as well from the batteries planted against Chapultepec as from Steptoe’s guns, which were served against the southern defences of the city in order to divert the attention of the enemy. At 8 A.M. the firing from the former ceased and the attack commenced. Quitman advanced along the Tacubaya road, Pillow from the Molino del Rey, which he had occupied on the evening before. Between the Molino and the castle lay first an open space, then a grove thickly planted with trees; in the latter Mexican sharpshooters had been posted, protected by an intrenchment on the border of the grove. Pillow sent Lieutenant-Colonel Johnstone with a party of voltigeurs to turn this work by a flank movement; it was handsomely accomplished, and, just as the voltigeurs broke through the redan, Pillow, with the main body, charged it in front and drove back the Mexicans. The grove gained, Pillow pressed forward to the foot of the rock; for the Mexican shot from the castle batteries, crashing through the trees, seemed even more terrible than it really was, and the troops were becoming restless. The Mexicans had retreated to a redoubt half-way up the hill; the voltigeurs sprang up from rock to rock, firing as they advanced, and followed by Hooker, Chase, and others, with parties of infantry. In a very few minutes the redoubt was gained, the garrison driven up the hill, and the voltigeurs, Ninth, and Fifteenth in hot pursuit after them. Here the firing from the castle was very severe. Colonel Ransom, of the Ninth, was killed, and Pillow himself was wounded.
