Another division, under Olid, fell upon the guns, captured them, and turned them upon the temples in which the troops were quartered; when the soldiers, whose loyalty to their commander had already been sapped, accepted the offer of Cortez of an amnesty for the past, and a full participation in the advantages of the conquest of the country. Having sworn allegiance to Cortez as captain general, they were incorporated in his little army.

In the morning, when they saw how small had been the body of men who had defeated them, many regretted the course they had taken, but in the course of the day the two thousand native allies from Chinantla arrived, and their military appearance, and the proof afforded by their presence of the influence of Cortez with the inhabitants of the country, put a stop to the murmuring; especially as Cortez ordered all the spoils taken from them to be returned, and distributed among them considerable sums of money--exciting, indeed, murmurs of discontent among his own veterans, who considered that they had been deprived of the spoil they had rightfully won.

The eloquence of their general, however, as usual, was successful in pacifying them; but to prevent further difficulties, he broke up his force, and sent off two hundred men under Diego de Ordaz, and a similar number under Velasquez de Leon, to form settlements on the coasts and rivers; and two hundred men to Vera Cruz, to dismantle the fleet of Narvaez.

Scarcely had these parties left when a messenger arrived with letters from Alvarado, saying that the Mexicans had risen and assaulted the Spaniards in their quarters, and had partly undermined the walls; and that, in the fighting, several of the garrison had been killed, and a great number wounded.

Cortez at once dispatched messengers after Velasquez and Ordaz, and ordered them to march to join him at Tlascala; recalled a hundred men from Vera Cruz, and then set forward. The troops suffered much in their march across the low country to the foot of the hills, beneath a sun of terrible power. However, they reached Tlascala, and were there joined by Ordaz and Velasquez. They were most hospitably entertained by their allies, and a number of levies joined them; and with these and eleven hundred Spaniards, of whom a hundred were cavalry, they marched towards Mexico.

They took a more northern route than before and, crossing the mountains, held their way on to Tezcuco. Upon their route through the plains the peasantry held aloof, and the greater portion of the population of Tezcuco withdrew before their arrival; and even its new lord, although appointed at the instigation of Cortez, was absent from the city. Dispatches arrived from Alvarado saying that the Mexicans had, for the last fortnight, ceased their attacks; but were blockading him in the palace.

Cortez marched down the lake shore on the following day, and crossed the causeway to the city. Not a native was to be seen near the line of march, not a boat was visible on the lake, and an air of gloom and solitude hung over everything; showing but too plainly the altered feelings with which the natives regarded the whites. The streets were similarly deserted. When the head of the column reached the palace, the gates were thrown open and the garrison rushed out to greet the newcomers, with joyful shouts.

Cortez now learned the reason of the rising of the Mexicans. It was the result of a hideous act of treachery, on the part of Alvarado. In the month of May was the great festival of the war god, which was held in his great temple; and the caziques asked permission of Alvarado to use, for the day, that portion which had been handed over to the Spaniards. He agreed to the request, on the condition that the Aztecs should celebrate no human sacrifices, and should come unarmed.

At least six hundred nobles attended, in their most gorgeous robes, and Alvarado and his soldiers were present as spectators. While the Aztecs were employed in a religious dance, Alvarado gave the signal, his men rushed upon them with their arms, and every one of them was massacred unresistingly, not a single soul escaping.

Various motives were assigned for this most foul massacre. Some writers have ascribed it solely to the desire for plunder; others to the desire of Alvarado to strike a blow that would intimidate the Mexicans from making any insurrectionary movement. Alvarado himself declared that he had information that the Mexicans intended to rise, but he gave no proofs, whatever, to justify his suspicions. The affair, indeed, seems to have been utterly indefensible, and must ever remain a foul blot upon Spanish honor.
