Scott, who was now at Tacubaya with Trist, held his troops at command--Worth and the dragoons at Tacubaya, Pillow at Mixcoac, Twiggs about four miles farther out, and Quitman at San Agustín--in such a manner as to be fairly safe himself, and to threaten the western and southern approaches of the city. The well men cleaned their clothes and arms, and the sick and wounded soon found themselves comfortable and cheerful. Several Mexican Congressmen among the prisoners were set free. About half a million of needed specie was obtained from the city--principally and perhaps entirely by cashing drafts on the United States government. A large quantity of provisions, contracted for while the Americans lay at Puebla, was brought out, and a train of wagons proceeded for the same purpose to the valley of Toluca, where Olaguíbel, ostensibly the implacable enemy of the Americans, helped them to obtain supplies. Apples, pears and peaches of an indifferent quality were now ripe, and the soldiers lived fairly well.[27.15] Santa Anna was even busier than Scott. Measures were taken to collect all missing soldiers, reorganize and rearrange the corps, maintain a state of defence, and revive morale by removing disaffected officers as well as by punishing conspicuous delinquents. All American prisoners in the city were freely given up. Gamboa, a politician of México state, caused some trouble by critically reviewing Santa Anna's course during the war, and formally charging him with treason. Far more serious was the combination of Valencia--who was still regarded by many as a martyr, had gathered a small army, and had pronounced against Santa Anna--with Olaguíbel, who stood on confidential terms with Alvarez; and to make this combination still more threatening, it seemed to be supported by Paredes, now at the head of a small force, by Almonte and by Canalizo. All possible care was taken to guard against the movement. Every officer known to have been associated with Valencia was imprisoned or at least cashiered; every hint of intrigue excited attention; and the government heard with deep concern that somebody on a sorrel horse had carried letters from Toluca to Querétaro. Naturally Santa Anna did not fail to assemble the generals, and offer his place to any one who would take it; and of course none of them had the bad taste--not to say imprudence--to come forward. Moreover behind all the military disaffection, rejoicing over it as a threat against Santa Anna, though unwilling to join forces with the army in any cause, towered the Coalition, justly regarded as even more dangerous.[27.15] [NEGOTIATIONS]
