During the Liberation War, the Northeast Field Army was the largest, most numerous, and most well-equipped unit among the major field armies, and this field army fought from the White Mountains and Black Water in the northeast to Hainan Island, making great achievements for the establishment of New China. During the liberation of Northeast China, the Workers' Party of Korea and the Korean Government headed by Kim Il Sung, as well as the Korean People's Army and the broad masses of the Korean people, provided a great deal of selfless support for the War of Liberation of Northeast China under the circumstance that Korea had just been liberated.
In July 1946, the Northeast Bureau established a Pyongyang office in Korea in order to establish a hidden rear in Korea. In October 1946, more than 100,000 Kuomintang troops launched an all-out attack on the Liaodong Liberation Army, including Andong, in three ways. In this case, the Northeast Field Army transferred logistics supplies, families, and wounded to North Korea. During the Great Strategic Transfer of Andong, more than 100,000 cadres, troops, and family members retreated to Korea or moved to the Changbai Mountains through Korea. From May to August 1946, logistics materials in the Tonghua area, the agrarian reform teaching regiment, the arsenal, the hospital, and the wounded women and children also crossed the Yalu River and were transferred to Korea. In order to help the Northeast Field Army transfer materials, North Korea also dispatched a large number of manpower and material resources.
During the liberation of Northeast China, North Korea also carried out a large amount of material assistance. After the Sino-Japanese War, Japan invaded and occupied Korea, and the armaments factories and many heavy industrial facilities were in the North Korean region, so there were not many Weapons for the Japanese army in Korea. At the beginning of the Liberation War, Kim Il-sung provided 100,000 guns to the Northeast Democratic Coalition Army. In addition, the DPRK also supported the Northeast Field Army in the production of weapons and ammunition of various raw materials, such as copper, iron, lead and other non-ferrous metals, as well as detonators, fuses, nitric acid, acetone, rubber shoes and so on.
In March 1946, the troops of the Jidong Military Subdistrict of the Northeast Democratic Coalition Army were severely short of weapons, and the North Koreans knew that they immediately assisted 1,000 sets of finished military uniforms and fine cloth that could make 10,000 sets of military uniforms, as well as a cart of wagon medicines. Throughout the Liberation War, North Korea aided more than 2,000 trainwrites of the Northeast Field Army.
In addition, our army also has a large number of military materials that are continuously transported between southern and northern Manchuria, inside and outside The Guan, and between international and domestic. During the Liberation War, the China Resources Company, which was established by the Chinese Communists in Hong Kong, chartered two soviet giant freighters and transported soybeans and other local specialties from the North Manchuria region from Korea to Hong Kong four times for sale, and then purchased the electronic equipment, medicines and other materials needed by our army and transported them back to the northeast. The East China Field Army and the Jin-Cha-Ji Field Army also have offices in Korea, and the Northeast Field Army has repeatedly transported some arsenals to Korea, then transferred them to the Shandong Peninsula, and finally distributed them to various liberated areas.
After the liberation war broke out in full swing, Kim Il Sung immediately called on young people in North Korea to join the Northeast Field Army as volunteers, and there were many Korean volunteers in the northeast at that time, most of which were incorporated into the Northeast Field Army. The Northeast Field Army finally formed these Korean officers and men into three Korean divisions, namely the 156th Division, the 164th Division, and the 166th Division. Many people say that these are formed by Koreans in China, but the concept of Koreans was only established after the founding of New China, and there was no such statement at that time, and many of these three divisions were actually Koreans. At the end of the Liberation War, the three Korean divisions were returned to the DPRK, and among the Korean officers and soldiers who returned to China, more than 2,000 people made great contributions to the founding of the country and more than 100 people were awarded the title of individual heroes.
