Meanwhile, Cortés received messages from several places in the neighborhood, intimating their desire to become the vassals of his sovereign and to be taken under his protection. The Spanish commander required, in return, that they should deliver up every Mexican who should set foot in their territories. Some noble Aztecs, who had been sent on a mission to these towns, were consequently delivered into his hands. He availed himself of it to employ them as bearers of a message to their master the emperor. In it he deprecated the necessity of the present hostilities. Those who had most injured him, he said, were no longer among the living. He was willing to forget the past, and invited the Mexicans, by a timely submission, to save their capital from the horrors of a siege.[322] Cortés had no expectation of producing any immediate result by this appeal. But he thought it might lie in the minds of the Mexicans, and that, if there was a party among them disposed to treat with him, it might afford them encouragement, as showing his own willingness to co-operate with their views. At this time, however, there was no division of opinion in the capital. The whole population seemed animated by a spirit of resistance, as one man. In a former page I have mentioned that it was the plan of Cortés, on entering the Valley, to commence operations by reducing the subordinate cities before striking at the capital itself, which, like some goodly tree whose roots had been severed one after another, would be thus left without support against the fury of the tempest. The first point of attack which he selected was the ancient city of Iztapalapan; a place containing fifty thousand inhabitants, according to his own account, and situated about six leagues distant, on the narrow tongue of land which divides the waters of the great salt lake from those of the fresh. It was the private domain of the last sovereign of Mexico; where, as the reader may remember, he entertained the white men the night before their entrance into the capital, and astonished them by the display of his princely gardens. To this monarch they owed no good will, for he had conducted the operations on the _noche triste_. He was, indeed, no more; but the people of his city entered heartily into his hatred of the strangers, and were now the most loyal vassals of the Mexican crown.
