Pizarro stood aghast at this desertion, in so critical a juncture, of those in whom he had most trusted. He was, for a moment, bewildered. The very ground on which he stood seemed to be crumbling beneath him. With this state of feeling among his soldiers, he saw that every minute of delay was fatal. He dared not wait for the assault, as he had intended, in his strong position, but instantly gave the word to advance. Gasca's general, Hinojosa, seeing the enemy in motion, gave similar orders to his own troops. Instantly the skirmishers and arquebusiers on the flanks moved rapidly forward, the artillery prepared to open their fire, and "the whole army," says the president in his own account of the affair, "advanced with steady step and perfect determination." 30But before a shot was fired, a column of arquebusiers, composed chiefly of Centeno's followers, abandoned their post, and marched directly over to the enemy. A squadron of horse, sent in pursuit of them, followed their example. The president instantly commanded his men to halt, unwilling to spill blood unnecessarily, as the rebel host was like to fall to pieces of itself.

Pizarro's faithful adherents were seized with a panic, as they saw themselves and their leader thus betrayed into the enemy's hands.

Further resistance was useless. Some threw down their arms and fled in the direction of Cuzco. Others sought to escape to the mountains; and some crossed to the opposite side, and surrendered themselves prisoners, hoping it was not too late to profit by the promises of grace. The Indian allies, on seeing the Spaniards falter, had been the first to go off the ground.31Pizarro, amidst the general wreck, found himself left with only a few cavaliers who disdained to fly. Stunned by the unexpected reverse of fortune, the unhappy chief could hardly comprehend his situation.
