The first thought of the Koreans was to fortify Cho-ryŭng Pass the one break in the mountain chain which the Japanese must pass if they wished to march on Seoul. Gen. Kwŭn Ryŭl with 23,000 men and other generals with troops hastily gathered from various districts hastened to that important pass and put the fortifications in good order, and the king forthwith sent Kwŭn Hyŭp as envoy to Nanking to implore the intervention of China. And now we see the evil results of Hideyoshi’s ill-treatment of the Chinese and Korean envoys in Japan; for instead of making the Koreans send time and again asking for help the Emperor was eager to send troops into the peninsula to avenge himself upon the Japanese. The Chinese army was put in charge of three men: Gen. Yang Ho with rank of Military Commissioner, Gen. Hyöng Kă as general-in chief and Admiral Ma Gwi as commander of all the naval forces. Under these were Generals Yang Wŭn, O Yu-ch’ung, U Păk-yŏng, Chin U-ch’ung, So Eung-gung, Chin Hyo and Tong Han-yu. Gen. Yang Ho came no further than P’yŭng-yang, his duties not requiring his presence on the field of battle. Admiral Ma Kwi and all the others came on to Seoul. From that point they branched out in several directions, one going to Nam-wŭn in Chŭl-la province, another to Song-ju in Kyŭng-sang Province, another to Chŭn-ju, Chŭl-la Province, and another to Ch’ung-ju in Ch’ung-ch’ŭng Province. Admiral Wŭn Kyun, who had supplanted Yi Sun-sin, went to Han-san where Admiral Yi had worked so diligently to build barracks with the proceeds of salt manufacture. His first work was to overthrow all the rules and regulations which his predecessor had so wisely promulgated. He then drove away all who had been at all intimate with the former admiral, who was now a common soldier under Kwŭn Ryul. He then built a paling about the council-hall that Yi Sun-sin had built and there he housed his harem and spent his time in revelry and feasting. He would frequently have innocent men called up and severely punished for mere amusement. And thus he soon alienated the good will of all the troops stationed there.
