The ground in front was of the rudest and roughest character. The troops made their way with difficulty over a broken tract called the Pedregal, bristling with sharp points of rocks, and which is represented as having been the crater of a now exhausted and extinct volcano. The enemy had thrown out skirmishers, who were posted in great force among the crevices and inequalities of this broken ground, and vigorously resisted the American advance; while the artillery of the intrenched camp played upon our troops, and shattered the very rocks over which they were to pass. General Pierce’s immediate command had never before been under such a fire of artillery. The enemy’s range was a little too high, or the havoc in our ranks must have been dreadful. In the midst of this fire, General Pierce, being the only officer mounted in the brigade, leaped his horse upon an abrupt eminence, and addressed the colonels and captains of the regiments, as they passed, in a few stirring words,--reminding them of the honor of their country, of the victory their steady valor would contribute to achieve. Pressing forward to the head of the column, he had nearly reached the practicable ground that lay beyond, when his horse slipped among the rocks, thrust his foot into a crevice, and fell, breaking his own leg, and crushing his rider heavily beneath him. Pierce’s mounted orderly soon came to his assistance. The general was stunned, and almost insensible. When partially recovered, he found himself suffering from severe bruises, and especially from a sprain of the left knee, which was undermost when the horse came down. The orderly assisted him to reach the shelter of a projecting rock; and as they made their way thither, a shell fell close beside them and exploded, covering them with earth. “That was a lucky miss,” said Pierce calmly. Leaving him in such shelter as the rock afforded, the orderly went in search of aid, and was fortunate to meet with Dr. Ritchie, of Virginia, who was attached to Pierce’s brigade, and was following in close proximity to the advancing column. The doctor administered to him as well as the circumstances would admit. Immediately on recovering his full consciousness, General Pierce had become anxious to rejoin his troops; and now, in opposition to Dr. Ritchie’s advice and remonstrances, he determined to proceed to the front. With pain and difficulty, and leaning on his orderly’s arm, he reached the battery commanded by Captain McGruder, where he found the horse of Lieutenant Johnson, who had just before received a mortal wound. In compliance with his wishes, he was assisted into the saddle; and, in answer to a remark that he would be unable to keep his seat, “Then,” said the general, “you must tie me on.” Whether his precaution was actually taken is a point upon which authorities differ; but at all events, with injuries so severe as would have sent almost any other man to the hospital, he rode forward into the battle.
