Garland, meanwhile, moved down rapidly on the right with Dunn’s guns, which were drawn by hand, all the horses having been wounded and become unmanageable. These soon opened an enfilading fire on the Mexican battery; and, some of the gunners flying, the light division charged, under a hot fire, and carried the guns for a second time. Their gallant leader was shot dead in the charge. But the enemy could afford to lose the battery. From the tops of the azoteas, from the Casa Mata, and the Molino, a deadly shower of balls was rained crosswise upon the assailants. Part of the reserve was brought up, and Dunn’s guns and the Mexican battery were served upon the buildings without much effect at first. Lieutenant-Colonel Graham led a party of the Eleventh against the latter; when within pistol-shot a terrific volley assailed him, wounding him in ten places. The gallant soldier quietly dismounted, pointed with his sword to the building, cried “Charge!” and sank dead on the field. There was an equally fierce fight at the other wing, where Duncan and McIntosh had driven in the enemy’s right toward the Casa Mata. McIntosh started to storm that fort; and, in the teeth of a tremendous hail of musketry, advanced to the ditch, only twenty-five yards from the work. There a ball knocked him down; it was his luck to be shot or bayoneted in every battle. Martin Scott took the command, but as he ordered the men forward he rolled lifeless into the ditch. Major Waite, the next in rank, had hardly seen him fall before he too was disabled. By whole companies the men were mowed down by the Mexican shot; but they stood their ground. At length some one gave the word to fall back, and the remnants of the brigade obeyed. Many wounded were left on the ground; among others Lieutenant Burnell shot in the leg, whom the Mexicans murdered when his comrades abandoned him. After the battle his body was found, and beside it his dog, moaning piteously and licking his dead master’s face. At the head of four thousand cavalry, Alvarez now menaced our left. Duncan watched them come, driving a cloud of dust before them, till they were within close range; then, opening with his wonderful rapidity, he shattered whole platoons at a discharge. Worth sent him word to be sure to keep the lancers in check. “Tell General Worth,” was his reply, “to make himself perfectly easy; I can whip twenty thousand of them.” So far as Alvarez was concerned, he kept his word.
