Major Dimmick, commanding the First Regiment of Artillery, says: "About 12 o'clock, M., the battalion was ordered to attack the position of the enemy at the church, reported by the engineers at the time to have but one piece of artillery. The point of attack selected by the senior engineer officer was masked by a corn-field, in front of which I deployed the battalion and ordered it to advance, when almost instantly a shower of musketry, grape and round shot poured upon us, under which the battalion advanced". "The right had advanced to within one hundred yards of a regular bastion front, the curtain of which had four pieces in embrasure, besides nearly a thousand infantry, both of which kept up such a constant stream of fire that I could not advance further in line; I therefore ordered the men to cover themselves as well as possible. The left of the battalion advanced to within seventy yards of the work, being exposed to the fire of two pieces of artillery, _en barbette_, in addition to the fire of a considerable force of infantry and some of them still nearer, so that they had a destructive fire on the cannoniers and infantry; which position the battalion maintained until the enemy were driven from their guns and bastion, when they were followed into their work and surrendered." (Ex. Doc. No. 1, Appendix, p. 78.) Captain Francis Taylor, commanding light battery, says: "On reaching Churubusco, we came in sight of a church, where the enemy was posted, having, as was supposed, an entrenched battery thrown across the road. Troops were soon thrown forward to attack this place; and, after a short time, I was ordered to place the battery in a position where it was thought I could drive the enemy from the roof and walls of the church, and sustain the other troops in their efforts to carry this place by storm. On taking the position assigned me, I found we were exposed to a most terrible fire of artillery and musketry, of a regular entrenchment, covering the front of the church to which we were opposite, and which the intervening Indian corn hid from our sight at the time. Here I opened my battery, and it was served with great precision for about an hour and a half, notwithstanding it was exposed, during that time, to a constant shower of grape, round shot, shell and musketry. At last, finding my loss was becoming very great, and having succeeded in driving the enemy from the roof and walls of the church, and given to our troops such support as was in my power, I determined to withdraw the pieces". (Ex. Doc. No. 1, Appendix, p. 73). The connection between the reconnaissance of the engineers, and the operations of the First Artillery and Taylor's battery at Churubusco, has already been described in extracts taken from my official report.
