Three months later the Manchu chief sent a letter to the Korean king, couched in the following terms, “I have seven causes for hating the Ming dynasty and it is impossible for me to keep my hands off them. Now you and I are not enemies. To be sure you have injured us more or less in the past, but we will waive all that. It will be necessary for you however to break off all connection with China and stop aiding her in any way.” Gen. Kang also wrote at the same time saying, “The Manchus are training all their youth to war, and soon they will have the whole of Liao-tung.” When the king received these letters he referred them to the governor of P’yŭng-an Province to answer. The answer ran as follows, “For two hundred years both you and we have been the subjects of the Ming power and now that trouble has arisen between you and the authorities at Nanking it will be bad for you and us as well. China is like a parent to us and how can we refuse to aid her? We cannot listen to your demand and abstain from helping her. If you will make peace with us and clearly define our boundaries and abstain from conquest, China will not be only glad but will reward us both with gifts.” To this the Manchu replied, “If you think that China will give presents you have been grievously deceived by her. They are all liars and cheats and I hate them. Put away this idea and stand shoulder to shoulder with us. We must take an oath and sacrifice a white horse to heaven and a black bullock to the earth. After that I will send back all your generals and soldiers. Let there be no more weapons used between us, but only horse-whips.” This latter refers to friendly intercourse by means of horses. Gen. Kang also wrote, “Norach’i has taken Puk-kwan and Gen. Kim T’ă-sŭk is dead. Păk Yang-go has surrendered. Norach’i has joined the Mongol forces to his own and is advancing on Yo-gwang. His two sons Mangoda and Hongtasi advise him to first seize Liao-tung. Every day there are long debates to discuss whether it were better to strike Liao-tung or Korea first. This is a secret but I am sure of what I say. They are making great numbers of ladders and I am sure they are intending to invade Korea first.” This letter troubled the King, for it interfered with his own personal comfort. So he sent a swift messenger to Nanking begging the Emperor to send a large force to “guard your eastern territory” which meant that the king wanted China to stand between him and this Manchurian scourge.
