The way lay through thick standing corn, and over marshy ground intersected with ditches, which were filled, or partially so, with water. Over some of the narrower of these Pierce leaped his horse. When the brigade had advanced about a mile, however, it found itself impeded by a ditch ten or twelve feet wide, and six or eight feet deep. It being impossible to leap it, General Pierce was lifted from his saddle, and in some incomprehensible way, hurt as he was, contrived to wade or scramble across this obstacle, leaving his horse on the hither side. The troops were now under fire. In the excitement of the battle he forgot his injury, and hurried forward, leading the brigade, a distance of two or three hundred yards. But the exhaustion of his frame, and particularly the anguish of his knee,--made more intolerable by such free use of it,-- was greater than any strength of nerve, or any degree of mental energy, could struggle against. He fell, faint and almost insensible, within full range of the enemy’s fire. It was proposed to bear him off the field; but, as some of his soldiers approached to lift him, he became aware of their purpose, and was partially revived by his determination to resist it. “No,” said he, with all the strength he had left, “don’t carry me off! Let me lie here!” And there he lay, under the tremendous fire of Churubusco, until the enemy, in total rout, was driven from the field. Immediately after the victory, when the city of Mexico lay at the mercy of the American commander, and might have been entered that very night, Santa Anna sent a flag of truce, proposing an armistice, with a view to negotiation for peace. It cannot be considered in any other light than as a very high and signal compliment to his gallantry in the field that General Pierce was appointed, by the commander-in-chief, one of the commissioners on our part, together with General Quitman and General Persifer F. Smith, to arrange the terms of this armistice. Pierce was unable to walk, or to mount his horse without assistance, when intelligence of his appointment reached him. He had not taken off his spurs nor slept an hour, for two nights; but he immediately obeyed the summons, was assisted into the saddle, and rode to Tacubaya, where, at the house of the British consul-general, the American and Mexican commissioners were assembled. The conference began late in the afternoon, and continued till four o’clock the next morning, when the articles were signed. Pierce then proceeded to the quarters of General Worth, in the village of Tacubaya, where he obtained an hour or two of repose. The expectation of General Scott, that further bloodshed might be avoided by means of the armistice, proved deceptive. Military operations, after a temporary interruption, were actively renewed; and on the 8th of September was fought the bloody battle of Molino del Rey, one of the fiercest and most destructive of the war.
