"At this time the First Artillery came up to where I was. The lamented and gallant Burke, at the head of the leading company, asked which direction they were to take. I inquired what were his orders. He said that the regiment was ordered to support the Rifles. I pointed to the smoke, which was all we could see by which to determine the position of our troops engaged in a corn-field on our right; told him that they reached their present place by moving farther to the rear, out of range of the works; and remarked to him that the fire through which he would have to pass in the direction he was going was very severe. He replied that they were ordered to move by that road to support the Rifles. The First Artillery filed by and soon encountered, at a distance of 150 yards from the enemy, the heaviest fire of artillery and musketry, followed almost immediately after [by that] brought to bear upon Taylor's battery, which had been ordered to fire upon the convent; and, in selecting a place suitable for managing the guns, had most unfortunately been placed, entirely exposed, directly in front of a well constructed battery with heavy pieces firing in embrasure." "As the First Artillery filed by me, I ordered my company to be formed, determined to go on with the reconnaissance; and if possible, send back to the general, [Twiggs,] accurate information in reference to the works of the enemy and the position of our own troops, which at that time I could not understand. In moving forward, I was opposite the centre of the [First] Artillery which inclined more to the left, toward the battery, whilst I kept nearer the [principal road leading almost due east from Coyoacan]. The ground was level, but some shelter was afforded to small bodies of men, by the ditches, maguey plant, etc. I ordered my men to separate, to shelter themselves as much as possible, [and] to keep within supporting distance of me. I proceeded about two hundred yards. I ordered every man to shelter himself in a small ditch which was fortunately near us; immediately after I heard the fire of Taylor's battery passing directly over my head. [When that fire commenced we were] in the corn-field, about half-way between Taylor's battery and the enemy. Requiring my command to lie close, with Lieutenant Foster, I made my way to an old ruined wall in the open space east of the corn-field, and from that position sent Lieutenant Foster to General Twiggs to report the extent of the line engaged on the right, that we were directly in front of the works [which were now in plain view], and that, in my opinion, the whole force under General Twiggs's command should turn the enemy's position by our left. Another battery [of the enemy] was seen distinctly to our right and far in rear of the Churubusco battery, apparently enfilading our line engaged on the right. General Twiggs had already sent Colonel Riley's brigade to turn the position by our left, and take the battery by the gorge. When Lieutenant Foster
