The unsolved mystery of the idol and temple continued to vex the Spaniards for many a year. When an indomitable soldier like Vasco Nuñez de Balboa found himself frustrated in the search for them, few others had the courage to take it up. It was not like Balboa to retire and acknowledge himself defeated, and it was much against his will that he turned his back upon the unseen Dobaybe and set his face towards Darien again. He did not, however, abandon the project utterly, and gave a pledge that he would sometime return, by leaving behind a body of thirty soldiers, under command of Bartolomé Hurtado, who were to hold the country in subjection. They took possession of a deserted village on the Rio Negro, and, while Balboa with the main body descended the river to Darien, ranged through the country in pursuit of fugitives.
From what afterwards transpired, it would seem that Cacique Zemaco had been playing a game of deep duplicity with his more civilized opponent, and, whether he held possession of the golden Dobaybe or not, had some sort of a stronghold in the mountains to which he could retreat on occasion, and which Balboa had not been able to reach. As soon as the latter's back was turned, he descended from his stronghold, and spread his warriors along the rivers, retaking the deserted villages and collecting their inhabitants together.
When Hurtado and his little band were left alone in the wilderness, Zemaco perceived an opportunity for revenge upon the Spaniards; but he was cautious and had a wholesome fear of their weapons. He waited until Hurtado had detached more than half his total force, for the purpose of taking their prisoners to Darien, and then launched his bolts of war. Hurtado's captives were placed in a large boat guarded by fifteen or twenty Spaniards, most of whom were invalided through wounds or sickness, and thus scarcely ten sound men remained behind in the Indian country. The boat descended the Rio Negro very slowly, for it was heavily laden with its human freightage, and late one afternoon, when between forest-covered banks that closely approached and cast a gloom upon the waters, it was attacked by Zemaco and his warriors. They were in four canoes, and were armed with war-clubs and lances. Shouting their war-cries, they surrounded the boat containing the Spaniards, and with the assistance of the prisoners massacred all save two. These two escaped by leaping into the river and clinging to the trunk of a great tree which was floating with the current. They hid themselves in the branches, and, being over-looked by the Indians, finally reached the shore and returned to Hurtado with their tidings of disaster. The commander was so disheartened that he at once abandoned his post on the Rio Negro and hastened to Darien with all speed. It is surprising that Zemaco did not attack him when on the way, as he had an overwhelming force, and his recent victory had inspired him with confidence; but as it afterwards was ascertained, he was then in secret conference with the caciques of all the provinces, four in number, for the purpose of totally exterminating the Spaniards. Hurtado carried the tidings of this conspiracy to Darien, having received intimation of it from a captive; but the inhabitants considered his fears of an uprising largely imaginary, incited by his recent disaster, and made no preparations for receiving the enemy if he should appear.
At this time there comes into view once more the beautiful Cacica, who had been left in Darien when Balboa went on his expedition up the Atrato. She had urged him to take her with him, saying that her place was by her lord and master's side; but he had refused, because, as he said, space on board the brigantine was limited, and there was room for soldiers only. He had given his house into her charge at parting, and when he returned she proudly showed him what she had done to improve its condition, receiving his praises therefor with great delight. But rumors soon reached Balboa that during his absence the Cacica had received under her roof a young warrior, who had come and gone at night—as a spy might have done, said the sentinels who watched outside the walls of the town. These rumors were verified by reports from the spies whom Balboa himself had left to watch the Cacica while he was away. He ardently loved her—of that there could be no doubt; but, as a Spaniard, he was naturally suspicious.
These spies were certain that the visiting Indian was a warrior of Zemaco's band, and thought he might be a relative of the Cacica, or a former lover whom Balboa had supplanted. They, too, sought to intercept him; but the wary Indian escaped them every time, and they could only report that he had been there and undoubtedly held conference with the Cacica. When Balboa heard these reports he was deeply disturbed, for, notwithstanding his suspicions, he wished to have confidence in his mistress, and disliked to think evil of her. He was uncertain whether he had better keep the information to himself, and meanwhile watch the girl narrowly for signs of deceit, or openly accuse her of treachery to his trust. He adopted a middle course, and one day, while they were conversing upon the events of the expedition, artfully contrived to involve her in the confession that hardly a day had passed in which she had not indirectly heard from him.
"And who was the messenger, my love?" asked Balboa, calmly, but with his heart beating furiously and his eyes flashing.
"My brother, sometimes, my cousin, and again my brother—for, you know, I have many brothers," replied the Cacica, artlessly.
"Yes, I know," rejoined Balboa. "But why should they come to you so frequently, and always at night?"
"Because I wanted tidings of you, my lord; and for that they could not come too often! At night, too, because they could not get within the town by daytime. For there were sentinels and spies, my lord. Did you not know there were spies?" asked the Cacica, archly, her eyes dancing mischievously.
"I—I knew there were spies," answered Balboa, hesitatingly. Then, suddenly assuming a stern and wrathful expression, he grasped the girl's wrists and, looking straight into her eyes, demanded: "What did your people tell you when they came to my house in the night-time? Did they say aught of the cacique Zemaco and of the conspiracy he is forming against me? Tell me, and truly, girl, for if thou liest thou mayst lose thy life!"
