Oñate prepared to march against the victorious rebels, as soon as the news of the disaster reached him, but when this was followed by additional information from the agents among the Indians, showing how widespread were the alliances of those who had begun the revolt, and that the Indians throughout the province of New Galicia were already in arms, he retired to Guadalajara. The defenses of this town were strengthened as much as possible, and messengers were dispatched to Mexico for reenforcements. The viceroy sent some soldiers and supplies, but this force was not sufficient to prevent the Indians—who were animated by their recent successes, by their numbers, by the knowledge of the weak points as well as of the strong ones in their oppressors, and [p409] who were guided by able leaders possessing all the prestige of religious authority—from attacking the frontier settlements and forcing the Spaniards to congregate in the larger towns. There was much fighting during the early summer of 1540, in which the settlers barely held their own. In August, the adelantado Pedro de Alvarado sailed into the harbor of La Natividad. As the news of his arrival spread, requests were sent to him from many directions, asking for help against the natives. One of the most urgent came from those who were defending the town of Purificacion, and Alvarado was about to start to their assistance, when a message from Mendoza changed his plans. The two men arranged for a personal interview at Tiripitio in Michoacan, where the estate of a relative afforded Alvarado a quasi neutral territory. After some difficulties had been overcome, the terms of an alliance were signed by both parties November 29, 1540. Each was to receive a small share in whatever had already been accomplished by the other, thus providing for any discoveries which might have rewarded Coronado’s search before this date. In the future, all conquests and gains were to be divided equally. It was agreed that the expenses of equipping the fleet and the army should offset each other, and that all future expenses should be shared alike. Each partner was allowed to spend a thousand castellanos de minas yearly, and all expenditure in excess of this sum required the consent of the other party. All accounts were to be balanced yearly, and any surplus due from one to the other was to be paid at once, under penalty of a fine, which was assured by the fact that half of it was to go into the royal treasury.
