Because the artillery rendered such signal service on the field yesterday Gen. Taylor was impressed with the idea that it was available for pursuit of cavalry in mountain passes, for storming entrenchments, or charging a line of battle. Having discovered the position of the enemy, the General had the trains parked on the prairie and left in charge of a battalion of foot artillery and the two eighteen pounders. May's dragoons were held in reserve on the prairie near where the road enters the woods.

These arrangements completed, our battery, now under the command of Ridgely, was ordered to advance, take the road through the woods and chaparral, and attack the enemy. Here then was the singular tactics of a battery of horse artillery all alone, leaving the entire army behind, moving down the road through the woods without any support whatever. Capt. Walker was our guide. He and I and Ridgely were in advance. We had gone half a mile or more when crash through the tree tops came a shot from the unseen batteries in front. "At a gallop, march," was the order, and on we went until the road turned to the left about forty-five degrees. At the turn we halted, and this gave us a battery front (in part) to their guns near the bank of the dry river. We could not see their guns, nor they see ours, owing to undergrowth, but the guns were discharged at the smoke that each other made. We kept advancing "by hand" down the road. Their skirmishers now began to annoy us. Ridgely came to me and said: "Go to Gen. Taylor and ask him to send some infantry supports." I got on my horse and galloped back up the road at full speed, met Gen. Taylor, Maj. Bliss, and other staff officers in the road, and delivered the message. The reply was: "The infantry has been deployed and will soon be there." I returned at a run. No one was to be seen anywhere. We had now been fighting the enemy's guns alone for more than a half hour, and had driven them from off the plain into the ravine or dry bed of the river, and had obtained possession of an open camping ground directly in front of their pieces and not over a hundred yards distant. Again Ridgely came and said: "Go to Gen. Taylor as quick as possible, and tell him to _send me_ assistance to capture the Mexican batteries in front of us." The road and also the woods on both sides were now full of our infantry moving forward. I soon met Gen. Taylor, delivered the message, adding: "General, their guns are just in our front and can be taken." His only answer was: "_My! my! G--d, where is May? I can't get him up!_"[8] Nothing more was said, and I returned. By this time our infantry was engaged with the enemy on the right of the road. The firing was very heavy. I had been back with my gun about ten minutes, when down the road came May, in column of fours; he halted and exclaimed: "Hello! Ridgely, where is that battery? I am ordered to charge it." Ridgely said: "Hold on, Charley, till I draw their fire, and you will soon see where they are." Our guns fired, and theirs replied. Away went May toward the Mexican guns, and our guns after him at a run. We came up to them muzzle to muzzle, only theirs were below the banks of the ravine and ours above. May had swept the gunners away and was out of sight on the other side in the chaparral. I was in command of the twelve-pound howitzer, and as I gave the order in battery, "Fire to the front!" a Mexican regiment behind some earthworks in the ravine and on the other side, with their right directly in front, fired a volley. Two drivers fell, the wheel locked the gun in turning, a horse fell, and it was with difficulty we could unlimber. I said to the sergeant, "Run for a canister," but before he got back a gunner slipped in a shell, and on top of that in went the canister. I could not prevent it, so great was the din of muskets. I fired the gun myself. The wheels were lifted from the ground. Two more canisters were fired before the regiment broke; but at that moment our infantry opened on them, and all was over in our immediate front. The second gun had horses killed, drivers and men shot, and it locked a wheel in the same way. Ridgely sprang from his horse and leaped into the dead driver's saddle, straightened the team, and that gun came into action. What the other two did I know not. Just as our firing ceased up rode Gen.
