The viceroy had not been long installed when he received news of a rebellion against the Spaniards by the Tarahumares, who inhabited portions of Chihuahua and Sinaloa, and who hitherto yielded implicitly to the gentle and persuasive voice of the evangelical teachers dwelling among them. The portion of this tribe inhabiting Sinaloa, commenced the assault, but the immediate cause of the rebellion is not known. We are not aware whether they experienced a severe local government at the hands of the Spaniards, whether they were tired of the presence of the children of the Peninsula, or whether they feared that the priestly rule was only another means of subjecting them more easily to the crown of Castile. Perhaps all these causes influenced the rebellion. Already in 1648, the chief of the nation had compromised three other tribes in the meditated outbreak; but, lacking the concerted action of the Tepehuanes and other bands, upon whose aid they confidently counted, they resolved to attack, alone, the village of San Francisco de Borja, whose garrison and village they slaughtered and burned. San Francisco was the settlement which supplied the local missions with provisions, and its loss was consequently irreparable to that portion of the country. As soon as the chief judge of Parral heard of this sanguinary onslaught he hastily gathered the neighboring farmers, herdsmen, and merchants, and hastened into the wilderness against the insurgents, who fled when they had destroyed the great depot of the Spaniards. The troops, hardy as they were on these distant frontiers, were not calculated for the rough warfare of woodsmen, and after some insignificant and unsuccessful skirmishes with the marauders, the new levies retired hastily to their homes. Fajardo, governor of Nueva Biscaya, soon heard of the rebellion and of the ineffectual efforts to suppress it. He was satisfied that no time was to be lost in crushing the rebellion, and, accordingly marched with Juan Barraza, to the seat of war with an adequate force. The Indians had meanwhile left their villages and betaken themselves to the mountains, woods and fastnesses. Fajardo immediately burned their abandoned habitations and desolated their cultivated fields; and when the Indians, who were now satisfied of their impotence, demanded peace, he granted it on condition that the four insurgent chiefs of the rebellion should be surrendered for punishment. The natives, in reply, brought him the head of one of their leaders, together with his wife and child; soon after another head was delivered to him, and, in a few days, the other two leaders surrendered.
