This period of rest and recuperation was broken in upon by the appearance, on the northern border, of Manchu troops under Yonggoldă and Omokdo. Rumors had again reached Manchuria that certain Korean officials had been advising against the Manchu power. As a result of this, four prominent officials were sent captive to the north. Early the following year King Chilga, the emperor’s brother, came to try these men, and held a proper court at which the Korean Crown Prince was present. Each of the accused men was brought in turn and questioned, and each had some plausible excuse to give. The result was sure from the beginning. They were all condemned and were thrown into a dungeon with a door in the top, a sort of Black Hole of Calcutta, where they all languished with cold, hunger and disease. They even excited the pity of their jailors, and when the Crown Prince plead for them before the emperor, they were ordered sent to Eui-ju, but heavily guarded. In 1640 the Japanese who had settled at Fusan complained that the harbor was too small, for it did not include the whole bay, but only that part directly in front of the settlement, which was about half way between the present Japanese town and the Korean town of Pu-san. The harbor was called Tu-mo Harbor. Consent to the enlargement of the harbor was refused. In 1641 Prince Kwang-hă, the deposed and banished wretch, died on the island of Quelpart. So great is the respect for royalty in the abstract, in Korea, that the king fasted four days, had the body brought up to Yang-ju and buried it with royal honors. To the one surviving daughter the king gave a comfortable house and an annuity. The next year a seditious movement was made by Ch‘oé Hyo-il of P‘yŭng-an Province, and two accomplices. They took boat for China, being provided with funds by the prefect of Eui-ju. Arriving at Teung-nă they joined the Chinese forces, received commissions in the Chinese army and despatched a letter to the prefect of Eui-ju asking him to gather a force and with them make a combined attack upon the Manchus. As fate would have it the Manchu Yonggoldă was at Eui-ju when this letter arrived, and it fell into his hands. He immediately sent to the king demanding the seizure and execution of all the men implicated in the plot. In spite of the expostulations of the Prime Minister, who wished to see only the prime movers punished, eleven men in Eui-ju and elsewhere were seized and met their fate before the palace gate in Seoul. That Japan and Korea had not forgotten each other is evinced by the fact that the Japanese emperor sent to the king asking him to suggest a name for an ancestral temple that he was erecting. The king declined but allowed his uncle to do it. The name suggested was “The Illustrious Place at Il-gwang Mountain.”
