CITY OF MEXICO. "Lieut. G. W. Smith, with the company and train under his command, reported to General Worth on the [San Cosme] causeway, [in the afternoon, September 13th], was informed that the wounding of Lieut. Stevens made him [Smith] the senior engineer of the attack then going on, and was instructed to go to the front, closely and carefully examine the state of affairs, return as soon as practicable, and report the best method of conducting the attack". He reported "that infantry alone on the left of the road could capture the gate, without artillery and with little loss, by making its way through the houses. He was ordered to take the engineer company and tools, return to the front, and carry out the plan proposed". (p. 476.) "The Mexicans did not remain long in front of Worth; after dark the signal for retreat of one command was given, and being heard by all, they left the buildings and scattered in all directions, their officers being unable to restrain them. In a little while, however, they repaired to the citadel. In one of the pavilions a council was held. Santa Anna presided, explained the untoward incidents of the day, and asked the opinions of those present as to whether or not the defence of the capital should be prolonged. There was discussion and opposition, but, Santa Anna announced his decision in these emphatic words: 'I resolve that this night this city must be evacuated'". (p. 480-1.) "At 1 o'clock A. M. of the 14th commissioners from the municipal government of the city approached the advanced post of Worth's command, were passed to his headquarters, and by him sent to General Scott's headquarters in Tacubaya". (p. 481.) "General Worth then directed the two engineer officers, serving with his command, to proceed to the front and with a detachment of infantry and the engineer company, closely examine all strong buildings, and direct operations toward the Main Plaza and National Palace. The senior engineer being directed to make known promptly any indication that the rumored evacuation was incorrect, reported that everything indicated that the Mexican army had abandoned the city".
