Tranquillity was again disturbed about the year 1770, under the government of Don Antonio Gil Gonzago, who absurdly endeavoured to compel the Araucanians to live in cities. Many councils were held to devise the most suitable means for carrying this chimerical scheme into execution, which was much ridiculed by those who were best acquainted with the dispositions of the Araucanians, while others sided with the governor in supposing it practicable. The Araucanians were informed of these intentions of the governor by their spies; and being apprehensive of danger to their liberties from the proposed innovation, their chiefs met secretly to deliberate upon the best measures for eluding the designs of the governor without having recourse to arms. On this occasion the following resolutions were entered into by the Butacoyog, or national assembly of the ulmens. 1st, To delay the business as long as possible, by equivocal replies and delusive promises. 2d, When pressed to commence building, to require tools and other necessary aids from the Spaniards. 3d, To have recourse to war, when they found themselves no longer able to elude the demands of the governor; but that only the provinces that were compelled to build should declare war, while the others remained neutral on purpose to mediate a peace. 4th, When the mediation of these should be refused, the whole confederacy to join in the war. 5th, To allow the missionaries to depart in safety, as they had nothing to accuse them of but being Spaniards. 6th, To elect a supreme toqui, who should have the charge of executing these resolutions, and was to have every thing in readiness for taking the field when necessary.—Accordingly Antivilu, apo-ulmen of Maquegua, was unanimously elected toqui; but as his province was one of those which were to remain neutral, he declined to accept the office, and Curignancu, brother to the ulmen of Encol was elected in his stead.
At the first conference, the governor proposed his plan to the Araucanians under every aspect that he thought might render it acceptable and agreeable. In pursuance of their previous agreement, the Araucanians objected, equivocated, and at length appeared to consent, but ended by requesting the necessary assistance for beginning the work. Accordingly, having pointed out the situations which he thought most eligible for the new cities, the governor sent them a great quantity of wrought iron, together with provisions for the labourers, and cattle for transporting the timber. As the work made no progress, the quarter-master Cabrito repaired to the frontiers with several companies of soldiers, to stimulate the tardy operations, and placed for this purpose superintendents in different quarters. The serjeant-major Rivera, was entrusted with the building of Nininco, and Captain Bargoa with that of another city on the banks of the Biobio, while Cabrito directed all the operations from his head-quarters at Angol.
