COLOCOLO (col-o-co'-lo), Molucho or Arauca-nian cacique, born about 1515; died in October, 1561. When Valdivia undertook the conquest of Arauco, Colocolo with 4,000 men and the cacique Aillavillu with his army set out to oppose the advance of the Spaniards. A fierce battle ensued, Colocolo dis- 694 COLQUITT tinguishing himself so much that at the death of Aillavillu he was given the command of both tribes. From 1551 till 1553 he directed many attacks upon the invaders under Valdivia, and, having united his troops with those of Caupolican, fought the famous battle of Tucapel, 2 December, 1553, in which Valdivia was defeated. The victory of the Indians was due to the plan of Colocolo, who divided his forces into thirteen bodies, to make them fight in turn, in order to have always fresh troops during the encounter. On the following day another battle was fought, Colocolo being at the head of his division, and the Spaniards were again routed. Accompanied by Lautor, he resisted in his intrenchments the attack of Villa-grin's army, 23 April, 1554. The Spanish chief was wounded, and retreated to Concepcidn, a City that, later in 1554, was captured and burned by Colo-colo. In 1555 he was besieged in the City of Val-divia by Villagran, and evacuated the place after a long resistance. At the end of the same year he fought a battle with Villagran at Biobio, but was again defeated. Two years later he commanded a division of Caupolican's army, had an encounter with Garcia de Mendoza at Monte Pinto, attacked with great fury his intrenchments three times, and was repelled each time by the Spaniards, losing 2,000 men. In November, 1557, he was defeated once more at the Arauco valley, and, Cau-polican having been taken prisoner, he succeeded him as chief of the Araucanian army. He kept up the war until 1559, when, being successful in several battles, he asked for peace, and signed the first treaty between the Spaniards and the Arauca-nians. Again, in October, 1561, he raised a large army against the conquerors, and lost his life in the terrible battle of Lomaco. Colocolo was not only celebrated for his great courage, but also considered the wisest cacique of his time.
