engineer company, was directed to slip along behind elevated ground, and fall upon the flank or rear of a Mexican force posted in advance; and the rest of it, marching by the left, was ordered to strike the camp and a large body of lancers on the flank. Even the possibility of a rear attack from Santa Anna, supposed to be still where he had been seen the evening before, was provided against. Meanwhile the troops that had remained in the pedregal, assembled as well as possible by Twiggs and Lee during the latter part of the night, in accordance with orders from Scott, watched and waited near Padierna under Colonel Ransom of the Ninth Infantry.[1]
Finally a slightly round-shouldered man, with blue eyes, a sandy mustache and sandy hair, walked slowly to the front and looked at his watch. It was about six o'clock.

Only a pair of 6-pounders bore on Riley, and they fired high. Soon the Mexicans at the breastwork, exchanging shots wildly with Ransom, found that bullets were coming from behind, leaped over the parapet and fled. Attacked by Smith's men, the lancers gave way and upset the rest of the infantry; and Riley's column, deployed as well as time and the ground would allow, bore down like a flood. All was now confusion in the camp: infantry, horse, artillery, mules, women, laborers in a mob.

Again General Smith drew out his watch. "It has taken just seventeen minutes," he remarked.[3]
Riley's brigade halted to secure the prisoners and the spoils, among which — to the frantic delight of the soldiers — were
