In the fourth moon of 1395 the embassy from China to Japan arrived in Seoul, and immediately Gen. Sim Yu-gyŭng posted southward to see Kato and tell him that the Chinese embassy had already come and that he must hasten to get all the Japanese troops out of the country before the embassy should arrive at Fusan. To all this the wily Kato answered gravely, “You had better stay here a few weeks while I take a run over to Japan and ask Hideyoshi about it, and if he gives the order to take the troops back, it can be done immediately.” When he came back, instead of answering the main question he said that it would be well for a Korean to accompany the envoy to Japan. Meanwhile the Chinese envoy Yi Chong-sŭng, in Seoul, sent messenger after messenger urging the speedy removal of the Japanese troops from the peninsula; but Kato kept putting it off on one ground or another, and made no move to go. When, however, this part of the comedy had proceeded to such a point that the Japanese began to fear the Chinese would see that it was indeed a comedy, Kato took a few regiments of men from Ung-ch’ŭn and Kŭ-je and made preparations as if to depart, meanwhile sending Gen. Sim to Seoul to say that he was waiting for the envoy and his suite to come south and accompany the departing army to Japan. Five months had already elapsed since the envoy had arrived in Seoul, and he therefore determined to accept this invitation. Moving southward, he came to Nam-wŭn in Chŭl-la Province where he stopped, fearing to go directly into the Japanese camp. While there he gained the soubriquet of “frog-eater,” for he was so fond of the flesh of that reptile that he compelled the people to hunt for and procure it for him.
