The Mongol forces at last reached the neighborhood of the Sung capital, where Kiassetao had succeeded in collecting an army of 130,000 men; but many of them were ill-trained, and the splendor of the camp provided a poor equivalent for the want of arms and discipline among the men. Kiassetao seems to have been ignorant of the danger of his position, for he sent an arrogant summons to the Mongols to retire, stating also that he would grant a peace based on the Yangtsekiang as a boundary. Bayan's simple reply to this notice was, "If you had really aimed at peace you would have made this proposition before we crossed the Kiang. Now that we are the masters of it, it is a little too late. Still if you sincerely desire it, come and see me in person, and we will discuss the necessary conditions." Very few of the Sung lieutenants offered a protracted resistance, and even the isolated cases of devotion were confined to the official class, who were more loyal than the mass of the people. Chao Maofa and his wife Yongchi put an end to their existence sooner than give up their charge at Chichow, but the garrison accepted the terms of the Mongols without compunction, and without thinking of their duty. Kiassetao attempted to resist the Mongol advance at Kien Kang, the modern Nankin, but after an engagement on land and water the Sungs were driven back, and their fleet only escaped destruction by retiring precipitately to the sea. After this success Nankin, surrendered without resistance, although its governor was a valiant and apparently a capable man. He committed suicide sooner than surrender, and among his papers was found a plan of campaign, after perusing which Bay an exclaimed, "Is it possible that the Sungs possessed a man capable of giving such prudent counsel? If they had paid heed to it, should we ever have reached this spot?" After this success Bayan pressed on with increased rather than diminished energy, and the Sung emperor and his court fled from the capital. Kublai showed an inclination to temporize and to negotiate, but Bayan would not brook any delay. "To relax your grip even for a moment on an enemy whom you have held by the throat for a hundred years would only be to give him time to recover his breath, to restore his forces, and in the end to cause us an infinity of trouble."
