The artillery was advanced a rod or two in front of the line, and opened fire. The infantry stood at order arms as spectators, watching the effect of our shots upon the enemy, and watching his shots so as to step out of their way. It could be seen that the eighteen-pounders and the howitzers did a great deal of execution. On our side there was little or no loss while we occupied this position. During the battle Major Ringgold, an accomplished and brave artillery officer, was mortally wounded, and Lieutenant Luther, also of the artillery, was struck. During the day several advances were made, and just at dusk it became evident that the Mexicans were falling back. We again advanced, and occupied at the close of the battle substantially the ground held by the enemy at the beginning. In this last move there was a brisk fire upon our troops, and some execution was done. One cannon-ball passed through our ranks, not far from me. It took off the head of an enlisted man, and the under jaw of Captain Page of my regiment, while the splinters from the musket of the killed soldier, and his brains and bones, knocked down two or three others, including one officer, Lieutenant Wallen,--hurting them more or less. Our casualties for the day were nine killed and forty-seven wounded.
At the break of day on the 9th, the army under Taylor was ready to renew the battle; but an advance showed that the enemy had entirely left our front during the night. The chaparral before us was impenetrable except where there were roads or trails, with occasionally clear or bare spots of small dimensions. A body of men penetrating it might easily be ambushed. It was better to have a few men caught in this way than the whole army, yet it was necessary that the garrison at the river should be relieved. To get to them the chaparral had to be passed. Thus I assume General Taylor reasoned. He halted the army not far in advance of the ground occupied by the Mexicans the day before, and selected Captain C. F. Smith, of the artillery, and Captain McCall, of my company, to take one hundred and fifty picked men each and find where the enemy had gone. This left me in command of the company, an honor and responsibility I thought very great.
Smith and McCall found no obstruction in the way of their advance until they came up to the succession of ponds, before describes, at Resaca. The Mexicans had passed them and formed their lines on the opposite bank. This position they had strengthened a little by throwing up dead trees and brush in their front, and by placing artillery to cover the approaches and open places. Smith and McCall deployed on each side of the road as well as they could, and engaged the enemy at long range. Word was sent back, and the advance of the whole army was at once commenced. As we came up we were deployed in like manner. I was with the right wing, and led my company through the thicket wherever a penetrable place could be found, taking advantage of any clear spot that would carry me towards the enemy. At last I got pretty close up without knowing it. The balls commenced to whistle very thick overhead, cutting the limbs of the chaparral right and left. We could not see the enemy, so I ordered my men to lie down, an order that did not have to be enforced. We kept our position until it became evident that the enemy were not firing at us, and then withdrew to find better ground to advance upon.
By this time some progress had been made on our left. A section of artillery had been captured by the cavalry, and some prisoners had been taken. The Mexicans were giving way all along the line, and many of them had, no doubt, left early. I at last found a clear space separating two ponds. There seemed to be a few men in front and I charged upon them with my company.
There was no resistance, and we captured a Mexican colonel, who had been wounded, and a few men. Just as I was sending them to the rear with a guard of two or three men, a private came from the front bringing back one of our officers, who had been badly wounded in advance of where I was. The ground had been charged over before. My exploit was equal to that of the soldier who boasted that he had cut off the leg of one of the enemy. When asked why he did not cut off his head, he replied: "Some one had done that before." This left no doubt in my mind but that the battle of Resaca de la Palma would have been won, just as it was, if I had not been there. There was no further resistance.
The evening of the 9th the army was encamped on its old ground near the Fort, and the garrison was relieved. The siege had lasted a number of days, but the casualties were few in number. Major Jacob Brown, of the 7th infantry, the commanding officer, had been killed, and in his honor the fort was named.
Since then a town of considerable importance has sprung up on the ground occupied by the fort and troops, which has also taken his name.
The battles of Palo Alto and Resaca de la Palma seemed to us engaged, as pretty important affairs; but we had only a faint conception of their magnitude until they were fought over in the North by the Press and the reports came back to us. At the same time, or about the same time, we learned that war existed between the United States and Mexico, by the acts of the latter country. On learning this fact General Taylor transferred our camps to the south or west bank of the river, and Matamoras was occupied. We then became the "Army of Invasion."
