Gen. Eul Neum was ordered to reduce P‘yŭng-yang and he approached to attack it but was driven back with a loss of 3,000 men. This attempt failing, the conquerors decided to lay siege to the town. When the inmates saw this they knew that the end was near. A plan was made whereby a part of the troops should make a sally from the West Gate and another part from the East Gate and together they hoped to dislodge the enemy. But one of the generals, instead of following out the plan, improved the opportunity to make good his escape. The other party was therefore in a trap and had to surrender. But still two generals held the city.
Meanwhile a band of 1,000 soldiers under Gen. Yang Kyu attacked Kwak-ju by night, and put the Kitan garrison to the sword, and took seven thousand people away to Tong-bu for safety.
When the Kitan forces found they were likely to have difficulty in bringing P‘yŭng-yang to terms they gave it up and marched away eastward. Thereupon the general Chi Ch‘oa-mun hastened to Song-do and announced that he had fled from P‘yŭng-yang. The “residency” of Ma Po-u seems to have been a short-lived one and terminated when it was found that the submission of the king amounted to little when the armies would not surrender. Courtiers urged an immediate surrender but Gen. Kang Kam-ch‘an said “If we could put them off a while and gain time they would be gradually worn out. The king should move south out of harm’s way for a time.” So that very night the king and queen and a large number of officials together with 5,000 troops moved southward to Chŭk-sŭng. The king’s southward flight was by no means an easy one. The very first night out from the capital the house where he slept was attacked by a band of traitors and malcontents. The king escaped to the mountains where he was attended by the faithful Gen. Chi. From this retreat he recalled the two generals who had been banished for attacking Yŭ-jin without orders, and restored them to their positions. Escorted by Generals Chi, Ch‘o and Chu, the king slowly retreated toward Wang-ju. All his numerous escort had left him excepting his two wives, two palace women and two intimate friends. Gen. Chi kept a sharp lookout for the bands of robbers who were roaming about the country. Once when hard pressed by these irresponsible gentry, Gen. Chi spirited the king away under cover of night and concealed him in To-bong monastery in Yang-ju a little to the northeast of the present Seoul, and the robbers were thrown completely off the scent.
