The alarming increase both in the frequency and the violence of the Japanese incursions gave scope for the development of the military genius of Gen. Yi Whan-jo, the father of the founder of this dynasty. He was appointed general of the west to guard against the freebooters. The people of Song-do were in dismay over the proximity of the dreaded Japanese and over the defeat of all the armies sent to put them down. Many civil officials took part in the martial preparations and even took the field in defense of their country. The Japanese were now penetrating Kyŭng-geui Province. In this year, 1360, they landed on Kang-wha, killed three hundred men and stole 40,000 bags of rice. So many men were in mourning that the king was obliged to curtail the period of mourning from three years to only a few days. The palace in Han-yang had now been completed and the king removed to that place, apparently because it was further from the sea shore and more difficult of access by the Japanese. Chapter X.

With the opening of the year 1361 Yi Whan-jo was appointed general of all the forces in the north and north-east. This was done against the advice of one of the officials who told the King that as Gen. Yi was from the north-east it was dangerous to appoint him general over the forces there, for untoward events were likely to happen. The king turned a deaf ear to this warning, which indeed was unnecessary, for the king had no more loyal subject that Yi Whan-jo. The king, having feasted the new appointee, sent him on his mission and himself returned to Song-do.
