Cortes, however, was too skilful to be enticed into giving battle under unfavourable circumstances. He temporized and succeeded in tiring out Narvaez and his troops, who retired to Zempoalla. Then Cortes, having taken his measures with consummate prudence, and the surprise and terror of a nocturnal attack which he organized compensating for the inferiority of his troops, he made prisoners of his enemy and all his soldiers, his own loss amounting to but two men. The conqueror treated the vanquished well, and gave them the choice between returning to Cuba, or remaining to share his fortune. This latter proposal, backed up as it was by gifts and promises, appeared so seductive to the new arrivals, that Cortes found himself at the head of 1000 soldiers, the day after he had been in danger of falling into the hands of Narvaez. This rapid change of fortune was turned to the greatest advantage by the skilful diplomacy of Cortes, who hastened to return to Mexico. The troops whom he had left there under the command of Alvarado, to guard the emperor and the treasure, were reduced to the last extremity by the natives, who had killed or wounded a great number of soldiers, and who kept the rest in a state of close blockade, while threatening them constantly with a general assault. It must be confessed that the imprudent and criminal conduct of the Spaniards, and notably the massacre of the most distinguished citizens of the empire during a fete, had brought about the rising which they dreaded, and which they had hoped to prevent. After having been joined by 2000 Tlascalans, Cortes pressed forward by forced marches towards the capital, where he arrived in safety, and found that the Indians had not destroyed the bridges belonging to the causeways and dikes which joined Mexico to the land. In spite of the arrival of this reinforcement, the situation did not improve. Each day it was necessary to engage in new combats, and to make sorties to clear the avenues leading to the palace occupied by the Spaniards.
