I wonder what our leaders would respond if fat kim sent similar letter to our president some day in the future. One thing I'm sure of is that China definitely won't fight a war for NK agian.

敬爱的毛泽东同志：

您对于为自己祖国的独立解放而斗争的朝鲜人民深切的关心、后方援助，我们谨代表朝鲜劳动党，表示衷心的感谢！

现在反对美帝国主义侵略者的我们朝鲜人民解放战争的今日战况，是在美国侵略军上陆仁川以前，我们战况不能不说不利于我们，敌人在连战连败的情况下，被我挤入朝鲜南端狭小的地区里，我们有可能争取最后决战的胜利。美帝军事威信极度的降低了。于是美帝国主义为挽回其威信，为实现其受朝鲜殖民地化与军事基地化之目的，即调动了驻太平洋方面陆海空军的差不多全部兵力，并于九月十六日以优势兵力，在仁川登陆后陆续占领了京城。

目前战况是极端严重了，我们人民军虽然对于上陆的敌人，进行了极顽强的抵抗，但对于前线的人民军已经造成了很不利的情况。

战争以来，敌人利用约千架的各种航空机，每天不分昼夜的任意的轰炸我们的前方与后方，在对敌空军毫无抵抗力的我们的面前，敌人则充分发挥其空军威力了。各战线上敌人在其空军的掩护下，活动大量机械化部队，我们受到的兵力与物质方面的损失是非常严重的，后方的交通运输通信及其他设施大量的被破坏，同时我们的机动力，则更加减弱了。

敌人登陆部队与南部战线的部队已经连接一起，切断了我们的南北部队，结果使我们在南部战线的人民军，处于被敌切断分割的不利情况里，得不到武器弹药，失掉联系，甚至于有一部分部队，则已被敌人分散包围着。如果京城完全被敌占领，则我们估计敌人可能继续向三八线以北地区进攻。如果不能急速改善我们的各种不利条件，则敌人的企图很可能会实现的。要保障我们的运输，供给，以及部队之机动力，则必须具备必要的空军，但是我们又没有准备好的飞机师。

敬爱的毛泽东同志，我们一定要决心克服一切的困难，不让敌人把朝鲜殖民地化与军事基地化！

我们一定要决心不惜流尽最后一滴血，为争取朝鲜人民的独立解放民主而斗争到底！

我们正在集中全力编训新的师团，集结在南部的十余只部队处于作战上有利的地区，动员全体人民，准备长期作战。

在目前敌人趁着我们严重的危急，不予我们时间，如果继续进攻三八线以北的地区，则只靠我们自己的力量，是难以克服此危机的。因此我们不得不请求您给予我们以特别的援助，即在敌人进攻三八线以北地区的情况下，极盼中国人民解放军直接出动援助我军作战！

我们向您提出以上意见，盼望即予指教！


敬礼

健康！

Dear Comrade Mao Zedong:

You deep concern for the Korean People's struggle for independence and liberation of their motherland, the rear of assistance, we would like on behalf of the Korean Workers Party, expressed his heartfelt thanks!

The Korean People's War of Liberation war, against the U.S. imperialist aggressors before the U.S. invasion forces landed in Incheon, fighting in favor of our enemies in the Lien-game losing streak, we went to Korea the southern end of a narrow areas, we have to fight for victory in the final battle. The military prestige of the U.S. imperialism is extremely reduced. So the U.S. imperialists to restore its credibility, in order to achieve the purpose of Korea's colonial and military bases, which is to mobilize nearly all the troops of the Armed Forces in the Pacific, and to the superior force on September 16 in Incheon landing after having occupied the capital.

The current war situation is extremely serious, our People's Army on the land of the enemy, very stubborn resistance, but the People's Army of the front line have resulted in a very unfavorable situation.

Since the war, the enemy about one thousand a variety of aviation, every day, regardless of any days and nights of bombing the front and rear, no resistance against the enemy air force in front of us, the enemy give full play to its air power . The enemy on all fronts under the cover of its air force, the activities of a large number of mechanized units, we are the troops and material loss is very serious, the rear of the transport communications and other facilities destroyed, and our machine power, more weakened.

Has been connected with the forces of the enemy landing forces with the southern front, and cut off the forces of the north and south, a result, our lack of arms and ammunition in the southern front of the People's Army, in the unfavorable situation of the enemy cut off the split, lose contact, and even part of the troops already be dispersed by the enemy surrounded. If the capital is completely enemy occupation, we estimate that the enemy is likely to continue to attack to the military demarcation line north of the region. If not rapidly improve the adverse conditions, the attempt of the enemy is likely to be realized. To protect our transportation, supply, and the forces of the machine power, you must have the necessary Air Force, but we have not prepared the pilots.

Dear Comrade Mao Zedong, we must have the determination to overcome all difficulties to prevent the enemy from the Korean colonization and military bases!

We must be determined at the shed the last drop of blood, to fight for independence and liberation of the Korean People's democratic struggle in the end!

We are concentrating fully compiled training new Division of dozen troops gathered in the south in the favorable areas on the combat and mobilization of all the people in preparation for the long haul.

The enemy took advantage of a serious emergency, not our time, continue to attack the military demarcation line north of the region, our own strength alone, it is difficult to overcome this crisis. Therefore, we have to ask you to give us special assistance in the region north of the military demarcation line of the enemy offensive, would appreciate the Chinese People's Liberation Army is directly dispatched assistance to our military operations!

We propose to you the above views, and look forward to forthwith advise!

Salute

Health!
