Meanwhile Quitman's brigade, conducted by an officer of engineers, had reached the eastern end of the city, and was placed under cover of the houses without much loss. Colonel Garland's brigade also arrived at the suburbs, and, by the assistance of some of our troops that had reached house-tops from which they could fire into a little battery covering the approaches to the lower end of the city, the battery was speedily captured and its guns were turned upon another work of the enemy. An entrance into the east end of the city was now secured, and the houses protected our troops so long as they were inactive. On the west General Worth had reached the Saltillo road after some fighting but without heavy loss. He turned from his new position and captured the forts on both heights in that quarter. This gave him possession of the upper or west end of Monterey. Troops from both Twiggs's and Butler's divisions were in possession of the east end of the town, but the Black Fort to the north of the town and the plaza in the centre were still in the possession of the enemy. Our camps at Walnut Springs, three miles away, were guarded by a company from each regiment. A regiment of Kentucky volunteers guarded the mortars and howitzers engaged against Black Fort. Practically Monterey was invested.
There was nothing done on the 22d by the United States troops; but the enemy kept up a harmless fire upon us from Black Fort and the batteries still in their possession at the east end of the city. During the night they evacuated these; so that on the morning of the 23d we held undisputed possession of the east end of Monterey.
Twiggs's division was at the lower end of the city, and well covered from the fire of the enemy. But the streets leading to the plaza—all Spanish or Spanish-American towns have near their centres a square called a plaza—were commanded from all directions by artillery. The houses were flat-roofed and but one or two stories high, and about the plaza the roofs were manned with infantry, the troops being protected from our fire by parapets made of sand-bags. All advances into the city were thus attended with much danger. While moving along streets which did not lead to the plaza, our men were protected from the fire, and from the view, of the enemy except at the crossings; but at these a volley of musketry and a discharge of grape-shot were invariably encountered. The 3d and 4th regiments of infantry made an advance nearly to the plaza in this way and with heavy loss. The loss of the 3d infantry in commissioned officers was especially severe. There were only five companies of the regiment and not over twelve officers present, and five of these officers were killed. When within a square of the plaza this small command, ten companies in all, was brought to a halt. Placing themselves under cover from the shots of the enemy, the men would watch to detect a head above the sand-bags on the neighboring houses. The exposure of a single head would bring a volley from our soldiers.
We had not occupied this position long when it was discovered that our ammunition was growing low. I volunteered to go back to the point we had started from, report our position to General Twiggs, and ask for ammunition to be forwarded.
[General Garland expressed a wish to get a message back to General Twiggs, his division commander, or General Taylor, to the effect that he was nearly out of ammunition and must have more sent to him, or otherwise be reinforced. Deeming the return dangerous he did not like to order any one to carry it, so he called for a volunteer. Lieutenant Grant offered his services, which were accepted.—PUBLISHERS.]
We were at this time occupying ground off from the street, in rear of the houses. My ride back was an exposed one. Before starting I adjusted myself on the side of my horse furthest from the enemy, and with only one foot holding to the cantle of the saddle, and an arm over the neck of the horse exposed, I started at full run. It was only at street crossings that my horse was under fire, but these I crossed at such a flying rate that generally I was past and under cover of the next block of houses before the enemy fired. I got out safely without a scratch.
At one place on my ride, I saw a sentry walking in front of a house, and stopped to inquire what he was doing there. Finding that the house was full of wounded American officers and soldiers, I dismounted and went in. I found there Captain Williams, of the Engineer Corps, wounded in the head, probably fatally, and Lieutenant Territt, also badly wounded his bowels protruding from his wound. There were quite a number of soldiers also. Promising them to report their situation, I left, readjusted myself to my horse, recommenced the run, and was soon with the troops at the east end. Before ammunition could be collected, the two regiments I had been with were seen returning, running the same gauntlet in getting out that they had passed in going in, but with comparatively little loss. The movement was countermanded and the troops were withdrawn. The poor wounded officers and men I had found, fell into the hands of the enemy during the night, and died.
While this was going on at the east, General Worth, with a small division of troops, was advancing towards the plaza from the opposite end of the city. He resorted to a better expedient for getting to the plaza—the citadel—than we did on the east. Instead of moving by the open streets, he advanced through the houses, cutting passageways from one to another. Without much loss of life, he got so near the plaza during the night that before morning, Ampudia, the Mexican commander, made overtures for the surrender of the city and garrison. This stopped all further hostilities. The terms of surrender were soon agreed upon. The prisoners were paroled and permitted to take their horses and personal property with them.
