About 3 A. M. on the 18th I sent one of my men to the foot of the hill to awaken Lieutenant Foster, who was sleeping there with the company, and tell him he must relieve me for the rest of the night.
After putting Foster in charge I started to join the company—and became sound asleep whilst walking down the hill. Stumbling into a quarry hole, I found myself sprawling on a dead Mexican soldier—his glazed eyes wide open, within a few inches of mine. For a moment I felt that horror of a corpse which many persons have, at times, experienced. The probability that, in a short time after daylight—in storming the strong position of the enemy—I might be as dead as the man upon whom I was lying, forced itself upon me.
Before I could regain my feet streams of men were rushing past me in the darkness; and I heard and recognised, the voice of Lieutenant Peter V. Hagner, of the Ordnance, calling in no measured tone or language, upon these stampeded men to stop. Whilst promptly aiding Hagner to bring the fugitives to a halt, I forgot the dead Mexican, and the whole train of thought connected with the corpse.
When something like order was restored on the hillside I learned from Lieutenant Hagner that he had been detailed to take one of our heavy guns up the hill to the battery. A regiment of Volunteers had been placed at his disposal to man the drag-ropes. Their arms had been left at the foot of the hill. On finding his way blocked by trees, Hagner had sent to procure axes from the engineer train; and in the meantime the regiment at the drag-ropes had been permitted to lie down. Of course they went to sleep. Suddenly awakened by a false alarm that the Mexicans were upon them, they rushed down the hill to get their arms. Hagner soon procured the required axes and the gun was delivered at the battery in good time.
At daylight I was again at the battery. A slight epaulment had been finished for three pieces of artillery, the platforms were laid, and the guns in position. I was then instructed by Captain Lee, to send ten men to report to him for special service; to order Lieutenant Foster with eight additional men, to report to him (Lee) for the purpose of opening a road for the light artillery around the foot of the heights; and I was ordered, with the rest of the company, to report to Colonel Harney, who was then in command of Persifor Smith's brigade, of Twiggs' division.
I was instructed to accompany that brigade when it moved forward to attack the enemy in position on a hill immediately in front of, and higher than that on which our battery had been constructed. The Mexicans were in strong force on the higher hill.
From our lower position we could not clearly see their lines nor determine how they were fortified. The hill they occupied was flat on top and their lines were set back from the crest of the precipitous slope which faced us. The storming brigade was ordered to halt and reform just before reaching the top of the higher hill. At this point they were below the plane of the enemy's fire, and were when lying down, perfectly protected. In this position they were ordered to rest, until the order should be given to rise, charge and carry the enemy's works by open assault.
When the line was thus formed, I requested Colonel Harney not to give the order to charge until I could go on the plateau, get a clear view of the enemy's works, and report their character. I soon informed him that their main line was not more than forty or fifty yards from where our men were then lying, that the fortifications were very incomplete, offered no effective obstacle, and we could dash over the works without a halt. I then ordered my men to drop their tools and use their muskets.
Whilst I was making this report to Colonel Harney, our attention was drawn to quite a sharp fire that the Mexicans had suddenly opened from a point close to the left flank and in the prolongation of our line. I told him I was certain there were no fortifications in that position; and I had seen no troops there. The fire increased from that direction, and Colonel Harney ordered me to proceed rapidly with my men to the left of our line, direct two companies on that flank to wheel at once, to the left; and when he gave the order to charge, these two companies and the engineers would move to the left against the force that was firing upon us from that side.
These dispositions on our left were made in a very few moments, and the order to charge was given immediately thereafter. The brigade sprang up, dashed over the short intervening space, and were almost instantly inside of the Mexican incomplete works.
