Pizarro took every precaution to prevent the escape or rescue of his prisoner, and for the first few weeks treated him kindly. The Spaniard was playing a profound diplomatic game. He well knew that Atahuallpa's generals would fear to endanger the latter's life by undertaking any aggressive measures, and that Huascar's partisans would take advantage of this providential opportunity to reorganise their forces. He conversed much with the captive emperor and at length began to hint to him the advisability of arbitration with Huascar. But the Inca took alarm and secretly sent off orders for his brother's execution. Seeing that the Indian was not to be cajoled, the Spaniard adopted a sterner attitude, pretended the greatest indignation at the fratricide, and soon had Atahuallpa willing to offer anything for his release. Shrewdly guessing that for gold the Spaniards would run any risk, the Inca negotiated for his ransom, saying: "I will fill this room with gold as high as I can reach if only you will liberate me." Pizarro agreed, insisting, however, that the ransom be delivered in advance at Cajamarca. A formal contract was drawn up and executed before a notary, and the deluded emperor ordered all preparations for war on the Spaniards to be interrupted and that the temples be stripped of their gold ornaments to supply the enormous amount he had promised. Under protection of this truce Pizarro sent out expeditions to explore the country and to expedite the process of gathering the treasure, and while this was going on Almagro arrived with reinforcements which doubled the Spanish forces. Finally the agreed sum was all in Cajamarca. It amounted to four million five hundred sterling in modern money. One-fifth was sent to the royal treasury and the remainder divided, making even the private soldiers rich for life. Nevertheless, Atahuallpa was not released. Large bodies of his troops were known to be on their way from Cuzco, and Pizarro realised that, once at the head of his forces, the Inca would wage an unrelenting warfare to expel the last Spaniard from Peru. If kept a prisoner his partisans would no longer hesitate to fight to release him, appreciating now the uselessness of relying on Spanish promises. He must be got rid of, and so after a mock trial in which he was charged with Huascar's murder and with conspiring against the Spaniards, the Inca emperor was strangled to death in the public square at Cajamarca. Pizarro knew better than to allow the Indians time to settle the disputed succession. With masterful sagacity he resolved to strike at Cuzco during the confusion. He suddenly evacuated Cajamarca and rapidly marched along the northern plateau, and over the Cerro de Pasco into the fertile valley of Jauja. From this point a short road led down the Cordillera to the sea, making it an admirable base for a campaign against Cuzco. [Illustration: OBSEQUIES OF ATAHUALLPA.
