September 13 In the victory of Molino del Rey, Magruder’s battery had taken little part. Jackson, posted with his section on the extreme flank of the line, had dispersed a column of cavalry which threatened a charge; but, with this brief interlude of action, he had been merely a spectator. At Chapultepec he was more fortunate. Pillow’s division, to which the battery was attached, attacked the Mexicans in front, while Worth’s division assailed them from the north. The 14th Infantry, connecting the two attacks, moved along a road which skirts the base of the hill, and Magruder was ordered to detach a section of his battery in support. Jackson was selected for the duty, and as he approached the enemy’s position dangers multiplied at every step. The ground alongside was so marshy that the guns were unable to leave the road. A Mexican fieldpiece, covered by a breastwork, raked the causeway from end to end, while from the heights of Chapultepec cannon of large calibre poured down a destructive fire. The infantry suffered terribly. It was impossible to advance along the narrow track; and when the guns were ordered up the situation was in no way bettered. Nearly every horse was killed or wounded. A deep ditch, cut across the road, hindered effective action, and the only position where reply to the enemy’s fire was possible lay beyond this obstacle. Despite the losses of his command Jackson managed to lift one gun across by hand. But his men became demoralised. They left their posts. The example of their lieutenant, walking up and down on the shot-swept road and exclaiming calmly, “There is no danger: see! I am not hit,” failed to inspire them with confidence. Many had already fallen. The infantry, with the exception of a small escort, which held its ground with difficulty, had disappeared; and General Worth, observing Jackson’s perilous situation, sent him orders to retire. He replied it was more dangerous to withdraw than to stand fast, and if they would give him fifty veterans he would rather attempt the capture of the breastwork. At this juncture Magruder, losing his horse as he galloped forward, reached the road.
The ditch was crowded with soldiers; many wounded; many already dead; many whose hearts had failed them. Beyond, on the narrow causeway, the one gun which Jackson had brought across the ditch was still in action.
Deserted by his gunners, and abandoned by the escort which had been ordered to support him, the young subaltern still held his ground. With the sole assistance of a sergeant, of stauncher mettle than the rest, he was loading and firing his solitary field-piece, rejoicing, as became the son of a warrior race, in the hot breath of battle, and still more in the isolation of his perilous position. To stand alone, in the forefront of the fight, defying the terrors from which others shrank, was the situation which of all others he most coveted; and under the walls of Chapultepec, answering shot for shot, and plying sponge and handspike with desperate energy, the fierce instincts of the soldier were fully gratified. Nor was Magruder the man to proffer prudent counsels. A second gun was hoisted across the ditch; the men rallied; the Mexican artillery was gradually overpowered, and the breastwork stormed. The crisis of the struggle was already past. Pillow’s troops had driven the enemy from their intrenchments at the base of the hill, and beneath the shadows of the majestic cypresses, which still bear the name of the Grove of Montezuma, and up the rugged slopes which tower above them, pressed the assaulting columns. A redoubt which stood midway up the height was carried. The Mexicans fell back from shelter to shelter; but amid smoke and flame the scaling ladders were borne across the castle ditch, and reared against the lofty walls were soon covered with streams of men. The leaders, hurled from the battlements on to the crowd below, failed to make good their footing, but there were others to take their places. The supports came thronging up; the enemy, assailed in front and flank, drew back disheartened, and after a short struggle the American colours, displayed upon the keep, announced to the citizens of Mexico that Chapultepec had been captured. Yet the victory was not complete. The greater part of the garrison had fled from their intrenchments before the castle had been stormed; and infantry, cavalry, and artillery, in wild confusion, were crowding in panic on the causeways. But their numbers were formidable, and the city, should the army be rallied, was capable of a protracted defence. Not a moment was to be lost if the battle was to be decisive of the war. The disorder on Chapultepec was hardly less than that which existed in the ranks of the defeated Mexicans. Many of the stormers had dispersed in search of plunder, and regiments and brigades had become hopelessly intermingled in the assault of the rocky hill. Still the pursuit was prompt. Towards the San Cosme Gate several of the younger officers, a lieutenant by name Ulysses Grant amongst the foremost, followed the enemy with such men as they could collect, and Jackson’s guns were soon abreast of the fighting line. His teams had been destroyed by the fire of the Mexican batteries. Those of his waggons, posted further to the rear, had partially escaped. To disengage the dead animals from the limbers and to replace them by others would have wasted many minutes, and he had eagerly suggested to Magruder that the guns should be attached to the waggon-limbers instead of to their own. Permission was given, and in a few moments his section was thundering past the cliffs of Chapultepec. Coming into action within close range of the flying Mexicans, every shot told on their demoralised masses; but before the San Cosme Gate the enemy made a last effort to avert defeat. Fresh troops were brought up to man the outworks; the houses and gardens which lined the road were filled with skirmishers; from the high parapets of the flat house-tops a hail of bullets struck the head of the pursuing column; and again and again the American infantry, without cover and with little space for movement, recoiled from the attack.
The situation of the invading army, despite the brilliant victory of Chapultepec, was not yet free from peril. The greater part of the Mexican forces was still intact. The city contained 180,000 inhabitants, and General Scott’s battalions had dwindled to the strength of a small division. In the various battles before the capital nearly 3,000 officers and men had fallen, and the soldiers who encompassed the walls of the great metropolis were spent with fighting.[[11]] One spark of the stubborn courage which bore Cortez and his paladins through the hosts of Montezuma might have made of that stately city a second Saragossa. It was eminently defensible. The churches, the convents, the public buildings, constructed with that solidity which is peculiarly Spanish, formed each of them a fortress. The broad streets, crossing each other at right angles, rendered concentration at any threatened point an easy matter, and beyond the walls were broad ditches and a deep canal.
Nor was the strength of the city the greatest of Scott’s difficulties. Vera Cruz, his base of operations, was two hundred and sixty miles distant; Puebla, his nearest supply-depot, eighty miles. He had abandoned his communications. His army was dependent for food on a hostile population. In moving round Lake Chalco, and attacking the city from the south, he had burned his boats. A siege or an investment were alike impossible. A short march would place the enemy’s army across his line of retreat, and nothing would have been easier for the Mexicans than to block the road where it passes between the sierras and the lake. Guerillas were already hovering in the hills; one single repulse before the gates of the capital would have raised the country in rear; and hemmed in by superior numbers, and harassed by a cavalry which was at least equal to the task of cutting off supplies, the handful of Americans must have cut their way through to Puebla or have succumbed to starvation.
Such considerations had doubtless been at the root of the temporising policy which had been pursued after Churubusco. But the uselessness of half-measures had then been proved. The conviction had become general that a desperate enterprise could only be pushed to a successful issue by desperate tactics, and every available battalion was hurried forward to the assault. Before the San Cosme Gate the pioneers were ordered up, and within the suburb pick and crowbar forced a passage from house to house. The guns, moving slowly forward, battered the crumbling masonry at closest range. The Mexicans were driven back from breastwork to breastwork; and a mountain howitzer, which Lieutenant Grant had posted on the tower of a neighbouring church, played with terrible effect, at a range of two or three hundred yards, on the defenders of the Gate.
By eight o’clock in the evening the suburb had been cleared, and the Americans were firmly established within the walls. To the south-east, before the Belen Gate, another column had been equally successful. During the night Santa Anna withdrew his troops, and when day dawned the white flag was seen flying from the citadel. After a sharp fight with 2,000 convicts whom the fugitive President had released, the invaders occupied the city, and the war was virtually at an end. From Cerro Gordo to Chapultepec the power of discipline had triumphed. An army of 30,000 men, fighting in their own country, and supported by a numerous artillery, had been defeated by an invading force of one-third the strength. Yet the Mexicans had shown no lack of courage. “At Chapultepec and Molino del Rey, as on many other occasions,” says Grant, “they stood up as well as any troops ever did.”[[12]] But their officers were inexperienced; the men were ill-instructed; and against an army of regular soldiers, well led and obedient, their untutored valour, notwithstanding their superior numbers, had proved of no avail. They had early become demoralised. Their strongest positions had been rendered useless by the able manœuvres of their adversaries. Everywhere they had been out-generalled. They had never been permitted to fight on the ground which they had prepared, and in almost every single engagement they had been surprised. Nor had the Government escaped the infection which had turned the hearts of the troops to water.
September 14 The energy of the pursuit after the fall of Chapultepec had wrought its full effect, and on September 14 the city of Mexico was surrendered, without further parley, to a force which, all told, amounted to less than 7,000 men.[[13]]
With such portion of his force as had not disbanded Santa Anna undertook the siege of Puebla; and the guerillas, largely reinforced from the army, waged a desultory warfare in the mountains. But these despairing efforts were without effect upon the occupation of the capital. The Puebla garrison beat back every attack; and the bands of irregular horse men were easily dispersed. During these operations Magruder’s battery remained with headquarters near the capital, and so far as Jackson was concerned all opportunities for distinction were past.
February 1848 The peace negotiations were protracted from September to the following February, and in their camps beyond the walls the American soldiers were fain to content themselves with their ordinary duties.
