FROM PUEBLA TO THE VALLEY OF MEXICO. "Riley's brigade was guided by Capt. Lee, assisted by Lieut. John G. Foster with ten men of the engineer company". (p. 287-8.) "It was the rule with General Scott that one of the only two regular divisions should always be in front. The engineer company headed the column. There was but one company of engineer soldiers in the United States army". (p. 339.) IN THE VALLEY OF MEXICO. "Beyond San Gregorio, the border of Xochimilco was skirted, and here obstructions in the road were first encountered, a ditch having been dug across it, and large stones rolled down from the hillside; but these obstacles were soon overcome by the engineer company with a detail from the leading brigade, while the Mexicans, who were firing from the heights above, were driven off by Colonel C. F. Smith's light battalion". (p. 355.) CONTRERAS. "The engineer company was recalled from Worth, and with a working party of 500 men, was ordered to make the road to Padierna practicable for artillery". (p. 362.) "When Smith's brigade advanced as described, the engineer company, under Lieut. G. W. Smith, went into action with the Third Infantry of that brigade". (p. 363.) "General Smith moved to his right and front across the _pedrigal_, the Rifles, with the engineer company at their head, leading". "At 2:30 A. M. of the 20th [August, 1847], the troops under General Smith began to form and take their places preparatory to the march which would bring them on Valencia's rear. Leading the Rifles in front of the brigade was the engineer company". (p. 369.) "The engineer company and the Rifles, being already in position in rear of the Mexican detachment, then rose and firing a volley upon it, and Riley continuing on upon them, they faced about, broke, and fled in the utmost precipitation to the main line in rear, pursued by Riley, the Rifles and engineer company". (p. 70.) CHURUBUSCO. "At Coyoacan General Scott joined, having previously ordered his columns to halt there. Lieut. I. I. Stevens, ordered about the same time to advance on the direct road and reconnoitre, was supported by the engineer company under Lieut. G. W. Smith. This reconnaissance covered the Convent of San Pablo in the village of Churubusco". (p. 378-9.) CHAPULTEPEC. "Battery No. 1 was constructed under Lieut. G. W. Smith's supervision, and Battery No. 2 under Lieut. G. B. McClellan's. Details were made from Quitman's division to assist the engineer company in the construction of these works, but although directed to report immediately after dark they did not arrive until near 4 A. M., of the 12th; hence these works, which were to have been finished before daylight, were hardly commenced by that time. The engineers were however, indefatigable, and the batteries were completed rapidly". (p. 452.)
