It is related that during the fight on that eventful night a body of Koryŭ troops collided with a company of the enemy and a melée ensued near the East Gate, where the soldiers trod on each other. Gen. Yi T‘ă-jo was there and was stabbed in the back with a spear. Finding himself in extremely narrow quarters he drew his sword and, hewing a path through the enemy, leaped the wall, horse and all, for he was in the saddle. The spectators thought he was a spirit. A volume might be filled with the stories of the wonderful achievements of this man, but most of them are figments of the imagination, invented at a later period to add lustre to the name of the founder of the dynasty. The capable leader Gen. Chöng Se-un, met the fate which has been the curse of Korean history from the beginning to the present time. Kim Yong-an, a jealous official, forged a royal order for his execution and sent it to Gen. An U who promptly carried it out. When the king learned of this he thought it was an incipient revolution but soon the other generals joined in a letter to His Majesty saying that it had been done because the murdered man was a traitor. The king accepted this as true and rewarded the murderers. The fortress of Sang-sŭng near the Tu-man River had long been under Mongol control and was governed by a Koryŭ renegade Cho Whi and afterwards by his descendants as a hereditary fief. Now when Koryŭ once more assumed control, Cho So-săng, the then chief of this anomalous settlement, fled to Mukden where he joined the banners of a wild tribe under the lead of Nap-t‘ap-chul, and proposed to them to make a raid into Koryŭ. This they did, crossing the Yalu and ravaging as far as Puk-ch‘ung and Hong-wŭn. This promised to become a serious matter, but the difficulty of the situation for Koryŭ was increased tenfold by a fresh invasion of the south by Japanese. The king was on his way back to Song-do when news of these two disasters reached him. Things looked desperate, but to add to the hopelessness of the situation the same Kim Yong-an who had murdered Gen. Chöng now compelled the king to kill Gen. An U on the ground that it was he who had killed Gen Chöng. The monster then proceeded to killed his own brother, and induced the king to put to death generals Yi Pang-sil and Kim Teuk-pă, two of the best surviving generals. It is a wonder that Gen. Yi T‘ă-jo was spared. Song-do had been so roughly handled that the king feared the historical records would be lost or destroyed; so he now sent men to look them up and put them in a place of safety.
