after the hereditary title of his family. Leaving it heavily garrisoned, he went on to Imperial for provisions. In his absence the Indians unsuccessfully tried to carry Canete by assault, and seeing the hopelessness of aggressive movements, they withdrew to the wooded districts and mountains, abandoning the open country and the sea-coast to the Spaniards. Mendoza pushed on beyond the southern limits of the Araucanian territory and discovered and explored the populous archipelago of Chiloe. On his way back he founded, on the mainland a hundred miles south of Valdivia, the city of Osorno. The Araucanians were now shut in between the Andes and a semicircle of towns and forts; it seemed as if their final subjection would only be a question of time. Mendoza returned to Santiago, leaving a lieutenant to undertake a campaign of raids and surprises. A few of the Araucanians remained in the field, and it was not until their veteran chief, Caupolican, was betrayed and pitilessly shot to death with arrows, that the whole confederacy again flew to arms under the command of his son. Marching on Concepcion, the Indians cut to pieces first one Spanish force of five hundred men and then another; and blockaded the city from the land side. The Spaniards, holding the sea, had no difficulty in pouring in reinforcements from Peru and Valparaiso, and the Indian army finally retreated. At Quiapo, between Concepcion and Canete, it was defeated and nearly annihilated, its most celebrated chiefs and heroes perishing in the slaughter. Once more the Araucanians retired to their forests and mountains while the Spaniards rebuilt and improved the line of fortifications and took possession of the valuable gold mines of Villarica. But they could make no further impression on these indomitable Indians. For forty years the war continued, sometimes active, sometimes desultory, and with constantly varying fortunes. Year after year the Spaniards poured in reinforcements, and their expeditions more than once ravaged the remotest parts of the Araucanian territory. But as soon as the armies retired the unflagging Indians would return to the attack, cutting off isolated bands of settlers and surprising forts and towns.
