As we all know, after the September 18 Incident, the Japanese Kwantung Army invaded and occupied the four northeastern provinces of our country within half a year, and in order to resist the brutal rule of the Japanese army, the Northeast Anti-Japanese Volunteer Army was the first to rise in the black land, and it grew to 300,000 people at its peak. After the defeat of the Volunteer Army, our party took over the banner of resistance against Japan and formed the Northeast Anti-Japanese Allied Army, which entered the heyday of the Northeast Anti-Japanese Federation from 1936 to 1937, with more than 30,000 troops and was organized into.
The 1st, 2nd, and 3rd Route Armies had 11 armies under their jurisdiction. After 1938, with the Kwantung Army and the puppet Manchurian army continued to clear and crusade, the Anti-Japanese Union entered the most difficult stage, and by 1940, the three fronts of the First Route Army of the Anti-Japanese Alliance, except for the commander-in-chief of the Second Front Army, Jin Chengzhu, led the 6th Division 88 cadres and soldiers to successfully arrive in the Soviet Union, the rest of the losses, Yang Jingyu, Cao Yafan and others sacrificed. There were more men and horses left in the Second Route Army and the Third Route Army, with more than 400 men in the Second Route Army and more than 300 in the Third Route Army arriving in the Soviet Union. 
On August 1, 1942, the 88th Independent Infantry Brigade of the Far Eastern Military Region, based on the remnants of the Northeast Anti-Japanese Federation, was formally established, codenamed Unit 8461, with Zhou Baozhong as the brigade commander of the major (promoted to lieutenant colonel in 1943), Li Zhaolin as the political commissar of the major, and Cui Shiquan as the deputy chief of staff of the lieutenant and secretary of the brigade party committee. It has 4 infantry battalions under its jurisdiction and a total of 8 battalion-level officers: Captain Jin, commander of the first battalion, and Captain Anji, political commissar;The commander of the second battalion, Senior Lieutenant Wang Xiaoming, and the political commissar, Senior Lieutenant Jiang Xintai. The commander of the 3rd Battalion, Senior Lieutenant Heo Hyung-sik (not yet in office, was actually succeeded by Captain Wang Minggui), and the political commissar, Senior Lieutenant Kim Chae;The commander of the fourth battalion, Senior Lieutenant Chai Shirong, and the battalion political commissar, Senior Lieutenant Ji Qing. So, how will these eight people develop in the future?
First of all, let's talk about the first battalion, the first battalion is the only South Manchurian anti-alliance armed force that reached the Soviet Union - the 6th Division of the 2nd Army of the 1st Route Army of the former Anti-Japanese Alliance. Captain Kim, everyone is familiar with it, so I won't mention it. Captain Anji was the former chief of staff of the 6th Division of the Anti-Japanese Alliance, and assisted Kim Sung-ju in many clever battles. After the victory of the Anti-Japanese War, he returned to Japan and founded the Pyongyang Academy to train military cadres. When the Security Cadre Training Brigade (the predecessor of the KPA) was established, Anji was appointed Chief of Staff of the Training Brigade. However, due to the excessive injuries he suffered in the long-term war against Japan, and the continuous overtime work after returning to Japan, he became ill from overwork, and died of illness in Pyongyang in December 1947. Let's talk about the second battalion, the second battalion is the remnants of the Seventh Army and the Fifth Army of the Second Route Army of the former Anti-Japanese Federation, and the battalion commander, Captain Wang Xiaoming, graduated from the Northeast Lecture Hall in his early years, and is one of the few generals who have received regular military school education in the Anti-Japanese Federation. In 1932, he participated in the anti-Japanese rescue, and was imprisoned after the failure, and was rescued by the organization two years later, officially joined the Anti-Japanese Federation, and successively served as the staff officer of the Fifth Army of the Anti-Japanese Alliance, the captain of the teaching team, the chief of staff of the Second Division, and the political commissar of the Seventh Army. 
After the victory of the Anti-Japanese War, he returned to China with the Soviet Red Army, formed the Huanan Guerrilla Brigade, and led his troops to Jinan to carry out the struggle against bandits. In May 1948, he served as the commander of the 11th Independent Division of Dongye and participated in the siege of Changchun. After the liberation of Changchun, he served as the commander of the Changchun garrison and the commander of the 164th Infantry Division. After the founding of the People's Republic of China, he served as the commander of the 6th Artillery Division of the Northeast Military Region, the president of the Naval Coastal Artillery School, the director of the Naval Coastal Defense Department, the director of the Naval Department of the General Supervision Department of the Military Commission, and the deputy commander of the Navy's Lushun Base, and was awarded the rank of major general in 1955. Political Commissar Captain Jiang Xintai, former political commissar of the 3rd Division and 9th Regiment of the 5th Army, although he is a political cadre, his military command ability is very prominent, and he can be called a military and political excellence. The most exciting thing is that in August 1939, Jiang Xintai commanded more than 30 people of the Ninth Regiment to raid the Hulin Heizuizi construction site, killing more than 40 Japanese guards and pursuing troops, 18 puppet Manchurian garrisons, and rescuing more than 2,000 laborers. In October 1940, Jiang Jian led more than 100 soldiers of the Ninth Regiment to attack the headquarters of the Huachuan Expedition Team and killed more than 80 Japanese soldiers. In the end, under the frenzied encirclement and suppression of a wing of the Japanese army, the remaining 20 soldiers of the Ninth Regiment successfully arrived in the Soviet Union under the command of Jiang Xintai. 
During the period of the 88th Brigade in the Far East, Jiang Xintai led the squad to fight many times, and he had the best record among the detachments. Zeng made a surprise attack on the railway station, the group tribe, and the puppet Manchurian military station, and buried the captured explosives on the Mengjiagang railway on the (An) Tujia (Musi) line. After the victory of the Anti-Japanese War, Jiang Xintai first led the personnel of the Anti-Japanese Federation to open up the Yanji base area, and then returned to China and served as the director of the Second Security Cadre Training Institute and the commander of the Ronan Division. After the establishment of the People's Army, he served as chief of the General Staff and formulated a plan for the southward advance. It is a pity that in the Third Battle of the Nakdong River, Jiang Xintai's command post was bombed by US planes and died a heroic death. The third battalion was formed by the remnants of the Third Route Army, and the battalion commander, Captain Xu Hengzhi, the former chief of staff of the Third Route Army of the Anti-Japanese Alliance, Li Zhaolin's favorite tiger general, and Zhao Shangzhi's right-hand man. When Zhao Shangzhi was fighting guerrillas in the Zhuhe, Hadong, and Daobei areas, he often liked to attack the east and the west, so Xu Hengzhi took on the task of sounding the east and led the team to attack the west. 
After the Anti-Japanese Union retreated into the Soviet Union, Xu Hengzhi led part of the staff of the General Headquarters of the Third Route Army and two small units to operate in the areas of Qing'an, Tieli, and Bayan. In July 1942, Xu Hengzhi took the guard ** Xiang to inspect the work in the Ba (Yan) and Mu (Lan) areas. On the way back, the guards lit a fire and cooked. The commander of the puppet army in Qing'an County found the cooking smoke in the valley and immediately surrounded it, and after more than two hours of fierce fighting, Xu Hengzhi and the guard ** Xiang died heroically at the age of thirty-three. During Xu Hengzhi's absence, Captain Wang Minggui actually served as the commander of the third battalion. Wang Minggui, a native of Panshi, Jilin, joined the Anti-Japanese Federation in his early years, and was promoted from a soldier to the commander of the Sixth Army in only four years, which shows the cruelty of the struggle against the United Nations and Wang Minggui's outstanding command ability. After the victory of the Anti-Japanese War, Wang Minggui was ordered to lead a 17-member team to Qiqihar City, and served as the deputy commander of the Qiqihar City Garrison Command, the commander of the Nenjiang Provincial People's Self-Defense Army Headquarters, the deputy commander of the Qiqihar Garrison Command, the commander of the Nenjiang Military Region, and the commander of the 8th Dongye Du Division. After the founding of the People's Republic of China, he served as deputy commander of the Heilongjiang Provincial Military Region. In 1955 he was awarded the rank of Major General. 
Political Commissar Kim Ce, former director of the Political Department of the Fourth Division of the Third Army of the Anti-Japanese Alliance, although he was a North Korean, he was diligent and studious, and after three years of participating in the revolution, he was able to skillfully write work reports in Chinese characters. Later, he was promoted to secretary of the North Manchurian Provincial Party Committee. At that time, the Soviet Union demanded that all cadres of the North Manchurian Provincial Party Committee in Northeast China be withdrawn, and Jin Ce thought that it would be more beneficial to continue to stay in Northeast China, so he persisted in the struggle in Harbin until 1943. After the victory of the Anti-Japanese War, Kim Chae returned to China and served as Deputy Prime Minister and Minister of Industry and Commander of the Front Command, and was awarded the rank of General of the People's Army. He died of heart palsy on January 31, 1951, at the age of 49. Finally, let's talk about the fourth battalion, the fourth battalion was adapted from the remnants of the Fifth Army of the Anti-Japanese Alliance, the battalion commander Chai Shirong, who participated in Wang Delin's rescue in the early years, was the commander of the fourth brigade, and carried out guerrilla operations in the Jidong area, the fourth brigade gradually became the firewood brigade in the south of Weizhen Daonan, in 1933, Chai Shirong led the fourth brigade to join the anti-Japanese Federation formed by Zhou Baozhong, and served as the deputy commander of the Fifth Army of the Anti-Japanese Alliance, and later served as the commander, Zhou Baozhong once praised: "I used to always say, fighting and counting Chai Shirong, but now it seems that it is not comprehensive enough, it should be said, 'conscientiously counting Chai Shirong'." ”
At the beginning of 1937, Chai Shirong commanded the Fifth Army to fight a beautiful ambush battle in Houdiao Ling, ambushing the Japanese army's military supplies team, killing more than 100 enemies, and taking more than 20 prisoners, and seizing a large number of military supplies, including food, ammunition, military blankets, fur coats, etc. The problem of the supply of the Fifth Army for several months was solved. After 1938, the Japanese invaders carried out a brutal sweep of the Fifth Army on the front line of the Mudanjiang River, Chai Shirong was in danger, skillfully carried out guerrilla warfare, and by 1941, the Fifth Army still had more than 100 people, and was ordered to retreat into the Soviet Union and be organized into the fourth battalion. Unfortunately, in September 1944, Chai Shirong was suddenly taken away while camping and training, and his whereabouts have been unknown ever since. Political Commissar Ji Qing, formerly known as Li Depei, a native of Yilan, Heilongjiang, engaged in underground work in his early years, served as the Propaganda Minister of the Yilan County Party Committee, Secretary of the Daonan Special Committee and other important positions, joined the Anti-Japanese Federation in 1936, and served as the secretary of the Military Department of the Fifth Army, the director of the Political Department of the Third Division, and the political commissar of the Fifth Army. In 1941, he retreated to the Soviet Union with the army, served as the political commissar of the fourth battalion, and worked with Chai Shirong for 6 years. In September 1944, Ji Qing was suddenly sent to Siberia, and it was not until 1955 that he was able to return to China, serving as the director of the old base area of the Heilongjiang Provincial Department of Civil Affairs and the deputy secretary-general of the Standing Committee of the Heilongjiang Provincial People's Congress. In 1984, he retired with the status of deputy provincial level.
