Thus Cristoval passed his convalescence, striving by incessant activity to hold his impatient longing. Twice only, after his strength returned, he rode to Yucay for a few brief hours of happiness.

The winter months passed and spring was at hand. Within the beleaguered city conditions grew desperate. Provisions, which had long been growing scanty, were almost exhausted, and the Spaniards faced starvation. They had hoped, watched, vowed many a pious vow, prayed many a fervent prayer, for reënforcements from the coast; but the expeditions sent by Francisco Pizarro for their relief had been entrapped in the mountains and driven back or annihilated. A few weeks must seal the fate of the besieged, and Hernando was already importuned by his cavaliers to lead in a final effort to cut through the investing lines and escape with his starveling remnant. Not he! He swore, and the stoutest of his men swore with him, to fight while strength remained to wield a blade.

But while the Spaniards were meeting in gloomy council the Inca was confronted by a situation no less grave.

Near the middle of a chill, clear night in the early spring, in the fifth month of the siege, Cristoval, now fully recovered, rode across the parade in front of the Inca's tent, and dismissed his native troopers. For a week he had been guarding the Cuntisuyu road, suspecting a Spanish design to break through the lines. He had laid off his helmet when a messenger summoned him to the Inca. Cristoval found Manco alone, pacing his tent with bent head, his face more deeply clouded than the cavalier had ever seen it. His expression lightened at sight of the man who had become nearer a comrade than any had ever been before, and he said gravely: "I have sent for thee, Cristoval, to entrust thee with a mission which, in other circumstances thou wouldst have found most welcome. Now it will be as painful to thee, I know, my friend and brother, as it is to me. It is this. Thou wilt ride to Yucay—wilt set out to-night. Arriving there, thou'lt conduct the household forthwith to the security of the fortress at Ollantaytambo."

Cristoval started. Was Yucay insecure? In Heaven's name, what could make it so, with the Spaniards held like starving rats? Manco read his question, and answered it bluntly:—

"We must raise the siege, Cristoval!"

Cristoval was aghast, unable to believe.

"We must raise the siege!" repeated Manco, steadily.

Cristoval put out his hand for the support of the table. When at last he spoke his voice was harsh and unnatural. "Raise the siege! Raise the siege—at this moment—when victory is within your grasp? By God, man, it must not be! Who hath advised this folly?"

Manco raised his hand. "It must be! I have held council all this day and to-night."
