Gen. Ha Kong-jin was at this time a hostage in the Kitan capital, and he managed to send a letter to the King informing him that the forces of Kitan were slowly retreating. This made it possible for the king to start on his way back to the capital. The first stage was to Chŭn-ju. The retreating forces of Kitan were again engaged at A-jin but as heavy reinforcements arrived at the moment, the Koryŭ generals, Yang Kyu and Kim Suk-heng, lost the day and fell upon the field of battle. This victory, however, did not stop the retreat of the invading army. There had been very heavy rains, and many horses had perished and many soldiers were practically without arms. Gen. Chon Song, who assumed command after the death of the two generals at K-jŭn, hung on the flanks of the retreating enemy and when half of them had crossed the Yalu he fell upon the remainder and many of them were cut down and many more were drowned in mid-stream. When it became known that all the Kitan forces were across the border it took but a few days to re-man the fortresses which had been deserted. The king now hastened northward stopping for a time at Kong-ju where the governor gave him his three daughters to wife. By the first he begat two sons both of whom became kings of Koryŭ, and by the second he begat another who also became king. He was soon on the road again, and ere long he reentered the gates of his capital which had undergone much hardship during his absence. His first act was to give presents to all the generals and to order that all the bones of the soldiers who had fallen be interred. He followed this up by dispatching an envoy to the Kitan thanking them for recalling their troops. He banished the governor of Chŭn-ju who had attempted his life. He repaired the wall of the capital and rebuilt the palace.
