This act of clemency and consideration is in beautiful contrast with the last malignant spitefulness of the conquered army, whose commander, unable to overthrow the invaders in fair combat, had released at midnight, the desperadoes from his prisons, with the hope that assassination might do the work which military skill and honorable valor had been unable to effect.
Meanwhile Santa Anna despatched a circular from the town of Guadalupe recounting to the Governors of the different States the loss of the capital, and, on the 16th, he issued a decree requiring Congress to assemble at Querétaro, which was designated as the future seat of government. As president and politician, he at once saw that he could do nothing more without compromising himself still further. Resigning, therefore, the executive chair in favor of his constitutional successor, Señor Peña-y-Peña, Chief Justice of the Supreme Court, he despatched General Herrera with four thousand troops to Querétaro, and departed to assail the Americans in Puebla. On the 18th he evacuated Guadalupe, and took the road to the eastward, with two thousand cavalry commanded by General Alvarez. He knew that the communication with our base of operations in that quarter was seriously interrupted if not entirely cut off; and he vainly hoped to recover his military prestige by some brilliant feat of arms over detached or unequal squadrons.
When Scott marched into the valley of Mexico, Puebla was left in charge of Colonel Childs, with four hundred efficient men and nearly eighteen hundred in his hospitals. The watchful commander and his small band preserved order until the false news of Mexican success at Molino del Rey was received. But, at that moment, the masses, joined by about three thousand troops under General Rea, a brave and accomplished Spaniard, rose upon, and besieged the slender garrison. On the 22d, Santa Anna arrived, and increasing the assailants to nearly eight thousand, made the most vigorous efforts during the six following days and nights to dislodge the Americans from the position they had seized.
