Gen. Chang Man started for Seoul, the advance guard being led by Chöng-sin, the skirmish line by Pak Yöng-sŭ, the right and left flanks by Yu Hyo-gŭl and Chang Tŭn, the sappers by Ch’o‘e, while the commissariat was in charge of An Mong-yun. The whole force consisted of 1800 men. The first day was spent in getting the army across the Ta-dong River. The next three days brought them to Whang-ju, where they fell in with part of the rebel army. After a brisk skirmish, two companies of cavalry were seen riding out from the rebel ranks as if to surrender, but when they had come close to Gen. Chang Man’s forces they made a sudden charge which threw the loyal forces into confusion and soon the entire army was routed. Turning from this complete victory, Yi Kwal led his forces to Su-an. It was his intention to approach Seoul by way of Sak-wŭn but as the government had a strong force there he changed his plan and came by Keui-rin which is an exceedingly rough road. Meanwhile Gen. Chang Man had collected the scattered remnants of his army and followed as far Sö-heung where he was joined by Gen. Yi Su-il and together they proceeded southward to P‘yŭng-san. There they were joined by 800 more troops. On the sixth of the moon Yi Kwal arrived at the Cho-t‘an ford and found it guarded by a royal force under Yi Chung-ho and Yi Tŭk-bu. Yi Kwal forced the passage and put the government troops to flight, taking the heads of both the generals. A day or so later, being met by more loyal troops, he sent them the two heads as warning. They did not heed it and in the fight that followed their leaders too lost their heads.
