The signal I had appointed for the attack was the momentary cessation of fire on the part of our heavy batteries. About 8 o'clock in the morning of the 13th, judging that the time had arrived by the effect of the missiles we had thrown, I sent an aid-de-camp to Pillow, and another to Quitman, with notice that the concerted signal was about to be given. Both columns now advanced with an alacrity that gave assurance of prompt success. The batteries, seizing opportunities, threw shots and shells upon the enemy over the heads of our men, with good effect, particularly at every attempt to re-enforce the works from without to meet our assault.
Major-General Pillow's approach, on the west side, lay through an open grove, filled with sharp-shooters, who were speedily dislodged; when being up with the front of the attack, and emerging into open space, at the foot of a rocky acclivity, that gallant leader was struck down by an agonizing wound. The immediate command devolved on Brigadier-General Cadwallader, in the absence of the senior brigadier (Pierce) of the same division, an invalid since the events of August 19. On a previous call of Pillow, Worth had just sent him a re-enforcement, Colonel Clarke's brigade.
The broken acclivity was still to be ascended, and a strong redoubt, midway, to be carried, before reaching the castle on the heights. The advance of our brave men, led by brave officers, though necessarily slow, was unwavering, over rocks, chasms, and mines, and under the hottest fire of cannon and musketry. The redoubt now yielded to resistless valor, and the shouts that followed announced to the castle the fate that impended. The enemy were steadily driven from shelter to shelter. The retreat allowed no time to fire a single mine, without the certainty of blowing up friend and foe. Those who at a distance attempted to apply matches to the long trains, were shot down by our men. There was death below, as well as above ground. At length the ditch and wall of the main work was reached; the scaling ladders were brought up and planted by the storming parties; some of the daring spirits first in the assault were cast down, killed or wounded; but a lodgment was soon made; streams of heroes followed; all opposition was overcome, and several of our regimental colors flung out from the upper walls, amidst long-continued shouts and cheers, which sent dismay into the capital. No scene could have been more animating or glorious.
Major-General Quitman, nobly supported by Brigadier-Generals Shields and Smith, (P. F.,) his other officers and men, was up with the part assigned him. Simultaneously with the movement on the west, he had gallantly approached the southeast of the same works, over a causeway with cuts and batteries, and defended by an army strongly posted outside, to the east of the works. Those formidable obstacles Quitman had to face, with but little shelter for his troops or space for manœuvring. Deep ditches flanked the causeway, made it difficult to cross on either side into the adjoining meadows, and these again were intersected by other ditches. Smith and his brigade had been early thrown out to make a sweep to the right, in order to present a front against the enemy's lines, (outside,) and to turn two intervening batteries near the foot of Chapultepec. This movement was also intended to support Quitman's storming parties, both on the causeway. The first of these, furnished by Twiggs' division, was commanded in succession by Captain Casey, 2d Infantry, and Captain Paul, 7th Infantry, after Casey had been severely wounded; and the second, originally under the gallant Major Twiggs, Marine Corps, killed, and then Captain Miller, 2d Pennsylvania Volunteers. The storming party, now commanded by Captain Paul, seconded by Captain Roberts, of the Rifles, Lieutenant Stewart, and others of the same regiment, Smith's brigade, carried the two batteries in the road, took some guns, with many prisoners, and drove the enemy posted behind in support. The New York and South Carolina Volunteers (Shields' brigade) and the 2d Pennsylvania Volunteers, all on the left of Quitman's line, together with portions of his storming parties, crossed the meadows in front, under a heavy fire, and entered the outer enclosure of Chapultepec just in time to join in the final assault from the west.
Besides Major-Generals Pillow and Quitman, Brigadier-Generals Shields, Smith, and Cadwallader, the following are the officers and corps most distinguished in those brilliant operations: The Voltigeur regiment in two detachments, commanded respectively by Colonel Andrews and Lieutenant-Colonel Johnstone, the latter mostly in the lead, accompanied by Major Caldwell; Captains Barnard and Biddle, of the same regiment, the former the first to plant a regimental color, and the latter among the first in the assault; the storming party of Worth's division, under Captain McKenzie, 2d Artillery, with Lieutenant Selden, 8th Infantry, early on the ladder and badly wounded; Lieutenant Armistead, 6th Infantry, the first to leap into the ditch to plant a ladder; Lieutenants Rodgers of the 4th, and J. P. Smith of the 5th Infantry, both mortally wounded; the 9th Infantry, under Colonel Ransom, who was killed while gallantly leading that gallant regiment, the 15th Infantry, under Lieutenant-Colonel Howard and Major Woods, with Captain Chase, whose company gallantly carried the redoubt, midway up the acclivity; Colonel Clarke's brigade (Worth's division) consisting of the 5th, 8th, and part of the 6th regiments of Infantry, commanded respectively by Captain Chapman, Major Montgomery, and Lieutenant Edward Johnson, the latter specially noticed, with Lieutenants Longstreet (badly wounded, advancing, colors in hand), Pickett, and Merchant, the last three of the 8th Infantry; portions of the United States marines, New York, South Carolina, and 2d Pennsylvania Volunteers, which, delayed with their division (Quitman's) by the hot engagement below, arrived just in time to participate in the assault of the heights, particularly a detachment under Lieutenant Reid, New York Volunteers, consisting of a company of the same, with one of marines; and another detachment, a portion of the storming party, (Twiggs' division, serving with Quitman,) under Lieutenant Steele, 2d Infantry, after the fall of Lieutenant Gantt, 7th Infantry.
In this connection, it is but just to recall the decisive effect of the heavy batteries, Nos. 1, 2, 3 and 4, commanded by those excellent officers, Captain Drum, 4th Artillery, assisted by Lieutenants Benjamin and Porter of his own company; Captain Brooks and Lieutenant Anderson, 2d Artillery, assisted by Lieutenant Russell, 4th Infantry, a volunteer; Lieutenants Hagner and Stone of the Ordnance, and Lieutenant Andrews, 3d Artillery; the whole superintended by Captain Huger, chief of Ordnance with this army, an officer distinguished by every kind of merit. The mountain howitzer battery, under Lieutenant Reno, of the Ordnance, deserves, also, to be particularly mentioned. Attached to the Voltigeurs, it followed the movements of that regiment, and again won applause.
In adding to the list of individuals of conspicuous merit, I must limit myself to a few of the many names which might be enumerated. Captain Hooker, assistant adjutant-general, who won special applause, successively, in the staff of Pillow and Cadwallader; Lieutenant Lovell, 4th Artillery (wounded), chief of Quitman's staff; Captain Page, assistant adjutant-general (wounded), and Lieutenant Hammond, 3d Artillery, both of Shields' staff, and Lieutenant Van Dorn (17th Infantry), aid-de-camp to Brigadier-General Smith.
Those operations all occurred on the west, southeast, and heights of Chapultepec. To the north and at the base of the mound, inaccessible on that side, the 11th Infantry, under Lieutenant-Colonel Hebert, the 14th, under Colonel Trousdale, and Captain Magruder's field battery, 1st Artillery: one section advanced under Lieutenant Jackson, all of Pillow's division, had, at the same time, some spirited affairs against superior numbers, driving the enemy from a battery in the road, and capturing a gun. In these, the officers and corps named gained merited praise. Colonel Trousdale, the commander, though twice wounded, continued on duty until the heights were carried.
Early in the morning of the 13th, I repeated the orders of the night before to Major-General Worth, to be, with his division, at hand to support the movement of Major-General Pillow from our left. The latter seems soon to have called for that entire division, standing momentarily in reserve, and Worth sent him Colonel Clarke's brigade. The call, if not unnecessary, was at least, from the circumstances, unknown to me at the time; for, soon observing that the very large body of the enemy, in the road in front of Major-General Quitman's right, was receiving re-enforcements from the city, less than a mile and a half to the east, I sent instructions to Worth, on our opposite flank, to turn Chapultepec with his division, and to proceed cautiously by the road at its northern base, in order, if not met by very superior numbers, to threaten or to attack, in rear, that body of the enemy. The movement, it was also believed, could not fail to distract and to intimidate the enemy generally.
Worth promptly advanced with his remaining brigade, Colonel Garland's, Lieutenant-Colonel C. F. Smith's light battalion, Lieutenant-Colonel Duncan's field battery, all of his division, and three squadrons of dragoons, under Major Sumner, which I had just ordered up to join in the movement.
