The Japanese Government had not been able as yet to put down the pirates, but now an envoy, Sin Hong, a monk, came with gifts declaring that the government was not a party to the expeditions of the freebooters and that it was very difficult to overcome them. And so the work went on, now on one coast of the country and now on another. The king sent an envoy to the Japanese Shogun, P‘ă-ga-dă, to ask his interference, but the shogun imprisoned the envoy and nearly starved him to death and then sent him back. The king wanted to send another, but the courtiers were all afraid. They all hated the wise and learned Chöng Mong-ju and told the king to send him. He was quite willing to go and, arriving at the palace of the shogun, he spoke out fearlessly and rehearsed the friendly relations that had existed between the two countries, and created a very good impression. He was very popular both with the shogun himself and with the Japanese courtiers and when he returned to Koryŭ the shogun sent a general, Chu Mang-in, as escort and also 200 Koreans who had at some previous time been taken captive. The shogun also so far complied with the king’s request as to break up the piratical settlements on the Sam-do or “Three islands.” A man named Im Sŭn-mu had learned among the Mongols the art of making gunpowder and a bureau was now formed to attend to its manufacture but as yet there were no firearms. With the opening of 1379 things looked blacker than ever. The Japanese were swarming in Ch‘ung-ch‘ŭng Province and on Kang-wha. The king was in mortal fear and had the walls of Song-do carefully guarded. Gen. Ch‘oe Yŭng was sent to hold them in check. The Japanese knew that no one but he stood between them and Song-do so they attacked him fiercely and soon put him to flight; but in the very nick of time Gen. Yi T‘ă-jo came up with his cavalry, turned the retreating forces about and attacked the enemy so fiercely that defeat was turned into a splendid victory. A messenger arrived breathless at the gate of Song-do saying that Gen. Ch‘oé had been defeated. All was instantly in turmoil; the king had all his valuables packed and was ready to flee at a moment’s warning. But lo! another messenger followed hard upon the heels of the first announcing that Gen. Yi had turned the tide of battle and had wrested victory from the teeth of the enemy.
