Separate note in reply to Eastern Jin (東眞)答東眞別紙
云云。夫所謂蒙古者。猜忍莫甚。雖和之不足以信之。則我朝之與好。非必出於本意。然如前書所通。越己卯歲於江東城。勢有不得已。因有和好之約。是以年前其軍馬之來也。彼雖背盟棄信。肆虐如此。我朝以爲寧使曲在彼耳。庶不欲效尤。故遂接遇如初。以禮遣之。今國朝雖遷徙都邑。當其軍馬之來。則猶待之彌篤。而彼尙略不顧此意。橫行遠近外境。殘暴寇掠。與昔尤甚。由是四方州郡。莫不嬰城堅守。或阻水自固。以觀其變。而彼益有呑啖之志。以圖攻取。則其在列郡。豈必拘國之指揮。與交包禍之人。自速養虎被噬之患耶。於是非特入守而已。或往往有因民之不忍。出與之戰。務獲官人及士卒。不爲不多矣。至今年十二月十六日。水州屬邑處仁部曲之小城。方與對戰。射中魁帥沙打里殺之。俘虜亦多。餘衆潰散。自是褫氣。不得安止。似已廻軍前去。然不以一時鳩集而歸。或先行或落後。欲東欲北。故不可指定日期。又莫知向甚處去也。請貴國密令偵牒可也。云云。
These Mongols, whatever they are, are jealous and cruel beyond measure, and even when they make peace they are not enough to be trusted. So our court's keeping on good terms with them has not necessarily come from its own intent either. Yet, as was told in the earlier letter, in the year Gimyo (己卯) at Gangdong fortress (江東城) the situation left no choice, and a pledge of peace came to be made.
Therefore last year, when their horsemen came, although they had broken their oath and cast away their faith and behaved cruelly in this fashion, our court chose rather to let the crookedness lie on their side and did not wish to copy their fault, and so in the end received and entertained them as at first and sent them off with ceremony. Now, though the country has moved its capital, when their horsemen came we entertained them the more generously still.
Even so they do not regard this intent in the least, but range at will over the outer territory far and near, harming and plundering more severely than before. For this reason there is no district anywhere in the four quarters that does not ring itself with walls and hold fast, or put water between and defend itself, and watch how things turn. Yet they harbour an ever greater will to swallow us and plot to attack and seize; how then should the several districts be bound to the country's direction alone, consorting with men who bear calamity in their arms and bringing upon themselves the trouble of rearing a tiger that will bite them?
And so they have not only gone in and held fast; at times, following the people's inability to endure it, they have gone out and fought, and have taken no small number of officers and soldiers. On the sixteenth day of the twelfth month of this year, at the small fortress of Cheoin-bugok (處仁部曲), a subject district of Suju (水州), while they were engaged in battle, they shot and struck down their chief general Sartai (沙打里) and killed him. Many too were taken captive, and the remaining host scattered. From this time their spirit has been broken and they cannot stay at ease, and it seems they have already turned their army and departed.
But they are not gathering and going back all at once; some go first and some lag behind, and they would go east and then would go north, so that the days cannot be reckoned and fixed, nor can it be known where they are going. It would be well for your country to have them secretly spied out.
