A new state of affairs began when the Araucanians, disgusted with the timid policy of their leader, chose a bolder man, named Caupolican, as their toqui, or head chief. A daring and able man, the new toqui soon taught the Spaniards a lesson. He began with an attack on their forts. At one of these, named Arauco, the invaders had eighty Indians employed in bringing them forage for their horses. The wily Caupolican replaced these laborers by eighty of his own warriors, who hid their arms in the bundles of hay they carried. On reaching the fort they were to attack the guards and hold the gates till their ambushed comrades could come to their aid. This device failed, the garrison attacking and driving back the forage-bearers before Caupolican could reach the place. Foiled in this, he made a fierce assault upon the fort, but the fire of eighty cannons proved too much for Indian means of defence, and the assailants were forced to draw back and convert their assault into a siege. This did not continue long before the Spaniards found themselves in peril of starvation. Vainly they sallied out on their assailants, who were not to be driven off; and finally, hopeless of holding the fort, the beleaguered garrison cut its way by a sudden night attack through the besieging lines and retired to the neighboring fort of Puren. A similar result took place at another fort called Tucapel, its garrison also seeking a refuge at Puren. When news of these events reached Valdivia, he saw that his conquests were in peril, and at once set out for the seat of war with all his forces, amounting to about two hundred Spaniards and four or five thousand Indians. A small party of cavalry were despatched in advance to reconnoitre the enemy, but they were all killed by the Araucanians and their heads were hung on roadside trees as a warning to their approaching comrades. This gruesome spectacle had much of the effect intended. On seeing it many of the Spaniards were dismayed and clamored to return. But Valdivia insisted on advancing, and on the 3d of December, 1553, the two armies came in sight of each other at Tucapel. Valdivia soon found that he had no ordinary Indians to deal with. These were not of the kind that could be dispersed by a squadron of cavalry. A fierce charge was made on his left wing, which was cut to pieces by the daring warriors of Caupolican. The right wing was also vigorously attacked. But the artillery and musketry of the Spaniards were mowing down the ranks of the Araucanians, whose rude war-clubs and spears were ill-fitted to cope with those death-dealing weapons. Driven back, and hundreds of them falling, they returned with heroic courage three times to the assault. But at length the slaughter became too great to bear and the warriors were ready to flee in dismay.
