Gen. Lane, after the landing and organization of his troops at Vera Cruz, with some 2500 men, started for Puebla, where it was understood that Col. Childs required reinforcement. Lane left Jalapa on the 1st of October, and hurried forward with Lally's command. At Perote, Lane learned that Santa Anna would throw himself upon his muscle, and give the advancing columns jessy at the pass of Pinal, and there was every prospect of a very tight time. Col. Wynkoop was in command at Perote; the men were anxious to be "in" at the fight in prospective, and Wynkoop obtained permission to join the General with four companies of the Pennsylvania Regiment; a small battery of the 3d Artillery, under command of Capt. Taylor, with Capts. Walker, of the Texan Rangers, and Lewis, of the Louisiana Cavalry. The column was now swelled to some 2800. They moved rapidly forward, and upon reaching Tamaris, Lane heard that the old fox was off--Santa Anna had gone to Huamantla. Lane determined to hunt him up with haste. The main force was left at Tamaris. Troops were forwarded--advanced by Walker's Rangers and Lewis's Cavalry--who approached to within sight, or nearly so, of Huamantla. The orders to Walker were to advance to the town, and if the Mexicans were in force, to wait for the Infantry to come up. Walker's command rated about 200 men. Upon reaching the outskirts of Huamantla, the Mexican Cavalry were seen dashing forward into the town, and the brave Walker ordered a pursuit. Santa Anna was evidently in the town. Capt. Walker, says his gallant comrade Lewis, made up his mind to be the captor of the wily old chief. The fair prospect of accomplishing the deed so excited Walker, that danger and death were alike secondary considerations, and so the command charged into the town. Some 500 lancers met the charge, but with terrific impetuosity the Rangers and Cavalry dashed in among them, cutting them down right and left, and soon sent them flying in all directions! It was at this moment, says Capt. Lewis, that one of the most heroic acts of bravery was performed, unsurpassed, perhaps, by any act of personal daring during the whole war! A tremendous negro, a fine, manly fellow, named Dave, belonging to Capt. Walker, with whom he was brought up--boys together--being mounted, and armed with a heavy sabre, dashed forward down a narrow street, (up which, a detached body of lancers were striving to escape,) and throwing himself between three poised lances and the person of Dr. Lamar, one of the surgeons, who would have been most inevitably torn to atoms, Dave raised himself in his saddle, and with a yell, and one fell swoop, the heroic fellow "chopped down" a lancer, clean and clear to his saddle! Two lancers pierced Dave's body, and he fell from his horse, dead!
