Of the arguments advanced by those who wished to hinder the expedition which Mendoza sent off under Coronado, none was urged more persistently than the claim that this undertaking would require all the men available for the protection of New Spain. It was suggested by all the parties to the litigation in Spain, was repeated by Cortes again and again, reappeared more than once during the visita of 1547, and was the cause of the depositions taken at Compostela on February 26, 1540. These last show the real state of affairs. The men who were withdrawn constituted a great resource in case of danger, but they were worse than useless to the community when things were peaceful. The Indians of New Spain had been quiet since the death of De la Torre, a few years before, but signs of danger, an increasing restlessness, unwilling obedience to the masters and encomenderos, and frequent gatherings, had been noticed by many besides Cortes. There were reasons enough to justify an Indian outbreak, some of them abuses which dated from the time of Nuño de Guzman, but there is every reason to suppose that the withdrawal of Coronado’s force, following the irritation which was inevitably caused by the necessity of collecting a large food supply and many servants, probably brought matters to a crisis. Oñate, to whom the administration of New Galicia had again been intrusted during the absence of his superior, began to prepare for the trouble which he foresaw almost as soon as Coronado was gone from the province. In April he learned that two tribes had rebelled and murdered one of their encomenderos. A force was sent to put down the revolt. The rebels requested a conference, and then, early next morning, surprised the camp, which was wholly unprepared for defense. Ten Spaniards, including the unwary commander, and nearly two hundred native allies were killed. Thus began the last and the fiercest struggle of the Indians of New Spain against their European conquerors—the Mixton war. [Illustration: LIV.
