Oñate learned of this, be sent an urgent request for help, telling of the serious straits in which he had been placed. The security of the province was essential to the successful prosecution of the plans of the new alliance. Alvarado immediately sent reinforcements to the different garrisons, and at the head of his main force hastened to Guadalajara, where ho arrived June 12, 1541. Oñate had received reports from the native allies and the Spanish outposts, who were best acquainted with the situation and plans of the hostile Indians, which led him to urge Alvarado to delay the attack until he could be certain of success. An additional force had been promised from Mexico, but Alvarado felt that the glory and the booty would both be greater if secured unaided. Scorning the advice of those who had been beaten by savages, he hastened to chastise the rebels. The campaign was a short one. On June 24 Alvarado reached the fortified height of Nochistlan, where he encountered such a deluge of men and of missiles that he was not able to maintain his ground, nor even to prevent the precipitate retreat of his soldiers. It was a terrible disaster, but one which reflected no discredit on Alvarado after the fighting began. The flight of the Spaniards continued after the Indians had grown tired of the chase. It was then that the adelantado tried to overtake his secretary, who had been one of those most eager to get away from the enemy. Alvarado was afoot, having dismounted in order to handle his men and control the retreat more easily, but he had almost caught up with his secretary, when the latter spurred his jaded horse up a rocky hill.

Alvarado survived long enough to be carried to Guadalajara and to make his will, dying on the 4th of July.
This disaster did not fully convince the viceroy of the seriousness of the situation. Fifty men had already started from Mexico, arriving in Guadalajara in July, where they increased the garrison to eighty five, Nothing more was done by Mendoza after he heard of the death of Alvarado. The Indians, emboldened by the complete failure of their enemies, renewed their efforts to drive the white men out of the land. They attacked Guadalajara on September 28, and easily destroyed all except the chief buildings in the center of the city, in which the garrison had fortified themselves as soon as they learned that an attack was about to be made. A fierce assault against these defenses was repulsed only after a hard struggle. The miraculous appearance of Saint Iago on his white steed and leading his army of allies, who blinded the idolatrous heathen, alone prevented the destruction of his faithful believers, according to the record of one contemporary chronicler. At last Mendoza realized that the situation was critical. A force of 450 Spaniards was raised, in addition to an auxiliary body of between 10,000 and 50,000 Aztec warriors. The native chieftains were rendered loyal by ample promises of wealth and honors, and the warriors were granted, for the first time, permission to use horses and Spanish
