Carvajal did not fail to take advantage of this favourable discovery, and immediately set about the acquisition of treasure for himself by every means which his present uncontroulable power afforded. In the first place, he appropriated to his own use all the Yanaconas, or Indian labourers in the mines, which had belonged, to such of the inhabitants as had opposed him, or to those who had died or fled from the province. He likewise appropriated to his own use above 10,000 Peruvian sheep, belonging to the Yanaconas of the crown or to individuals, which were employed in transporting provisions for the miners. By these means, he amassed in a short time near 200,000 crowns, all of which he retained to his own use. His soldiers were so much dissatisfied with his conduct, as he gave them no share of his exactions, that they plotted together against him. Luis Pardamo, Alfonso de Comargo, Diego de Balsameda, and Diego de Luxan, with thirty others, who had entered into this conspiracy, had determined to put him to death about a month after his arrival in La Plata from his expedition against Mendoza; but, owing to some obstacles, they had been induced to deter the execution of their enterprize to a future period. By some unknown means the circumstances of this plot came to the knowledge of Carvajal, who put to death the before-mentioned leaders of the conspiracy, and ten or twelve others, and banished all the rest. By these merciless executions, in which he indulged on all occasions, Carvajal inspired so much terror that no one dared in future to make any similar attempt; as he not only punished in the severest manner all who evinced any intention of revolt, but put people to death on the slightest suspicion. Owing to this the loyal servants of his majesty may assuredly be exculpated from the blame which has been imputed to them, for not putting Carvajal to death: In reality, there were many persons sufficiently anxious to have done so, on purpose to escape from the cruel tyranny under which they groaned in secret; and four or five conspiracies were entered into for the purpose, which were all discovered, and occasioned the destruction of at least fifty individuals. By these means every one was terrified from attempting any thing against him, more especially as he gave high rewards to all who communicated any intelligence of the kind, so that all were forced to temporize and to wait in anxious hope of some favourable opportunity to deliver them from his cruel tyranny. Carvajal continued to remain at La Plata, frequently publishing accounts of the successes of Gonzalo Pizarro, to whom he often sent large remittances; derived from his own resources, from the royal fifths which he appropriated, and from the confiscated estates of those whom he put to death, all of which he seized upon, under pretence of supplying funds for prosecuting the war.
