When the news of this exodus from the capital and the driving out of the Mongol governors reached the Mongol capital is caused a sensation. The emperor, in a white heat, sent a messenger post-haste to Song-do and behind him came a powerful army. The demand was “Why have you changed the capital? Why have our people been driven out?” The king replied that the capital was changed because all the people were running away, but he affirmed that although he had removed to Kang-wha his friendly feelings toward the Mongols had not changed. To this the Mongols made the only answer that was to be expected from them. They fell upon the northern towns and put them to indiscriminate slaughter. Men, women and children fell beneath their swords. Gen. Sal Ye-t‘ap himself came to attack Cho-im fortress. In that place there was a notable archer. He shot with unerring skill and every arrow found its victim. Aided by this man the garrison offered such a stubborn resistance that the Mongols at last fell back in disorder. It is said that Gen. Sal Ye-t‘ap himself was one of the victims of this man’s superb marksmanship. The king offered him official position but he would not accept it. The spring of 1233 found the emperor’s anger somewhat abated and instead of sending another army he sent another envoy with four formulated charges. (1) No Koryŭ envoy had come to do obeisance. (2) Highwaymen had killed a Mongol envoy. (3) The king had run away from his capital. (4) The king had given false figures in the census of Koryŭ. We are not told whether these were answered but we may infer that they were, and in the humblest tone.
