From November 1948 to January 1949, the heroic People's Army successfully completed the reorganization of the troops. Five field armies were formed, with a total of 16 corps. The First Field Army has two corps, the Second Field Army and the North China Field Army have three corps, and the Third Field Army and the Fourth Field Army have four corps.
After the establishment of the five major field armies, each of them had its own combat tasks and liberated areas. Presumably, friends who know history know that Ichino liberated the northwest, Erye and Sanye jointly launched the Battle of Crossing the River, the Third Field Army liberated Shanghai and Nanjing, and the Second Field Army liberated Jiangsu and Zhejiang. Subsequently, the Third Field Army marched to the southeast and the Second Field Army to the southwest. After winning the Battle of Pingjin, the Fourth Field Army went all the way south, in the central and southern regions, liberated Hunan and Hubei, continued to pursue and annihilate the south, liberated Guangdong and Guangxi, and annihilated the Bai Chongxi military group. The North China Field Army stayed in North China to eliminate the criminal and evil forces in Beiping City and prepare to welcome the leaders into Beiping City, so the field army took on the task of guarding.
Just when the five major field armies were each completing their own combat tasks, due to the needs of the war situation. Of the 16 corps under the jurisdiction of the five major field armies, three corps fought across two field armies on the battlefield of liberation.
The first corps to fight across two field armies was the Fourth Corps. I believe many people know that the commander of the Fourth Corps is Chen Geng, and the corps is subordinate to the Second Field Army. After participating in the Battle of the Crossing River, Chen Geng's Fourth Corps was transferred to the Fourth Field Army under the command of Lin, and was tasked with a major detour, the purpose of which was to prevent Bai Chongxi's military group from escaping abroad. The brave and invincible Fourth Corps, under the command of commander Chen Geng, successfully completed the combat tasks entrusted to them by their superiors. Outside the city of Guangzhou, the 15th Corps was formed, and the two corps then jointly launched a campaign to liberate Guangzhou.
The morale-boosting KPA soon defeated the garrison of Canton, and the 15th Corps entered Canton to maintain law and order. The Fourth Corps did not enter Guangzhou, but was on the periphery, pursuing and annihilating the Nationalist troops who had escaped from Guangzhou. The fourth corps of soldiers and soldiers, in this pursuit and annihilation operation, annihilated more than 40,000 enemy troops. It was also after the end of this pursuit and annihilation that the Fourth Corps was transferred back to the Second Field Army to fight, marching into the southwest and participating in the battle to liberate Yunnan. In this way, General Chen Geng's Fourth Corps successively crossed the Fourth Field Army and the Second Field Army on the battlefield of liberation, and both achieved brilliant results.
The second regiment to fight across two field armies was the 18th Corps. I believe that friends who understand the history of the Liberation War know that the predecessor of the 18th Corps was the First Corps of North China, and the main task during the Liberation War was to liberate Shanxi and annihilate the Yan Xishan military clique. The commander of the corps was Xu Shuai, and the deputy commander of the corps was Zhou Shidi, the first corps of north China in 1949, which was reorganized into the 18th Corps of the North China Field Army. Due to the previous corps commander Xu Shuai, he was tired in commanding the Battle of Taiyuan. In this way, after being reorganized into the 18th Corps, the commander of the corps was General Zhou Shidi, and the commander-in-chief of the Taiyuan Campaign was also replaced by General Peng.
Originally, the 18th Corps belonged to the North China Field Army, but after the Battle of Taiyuan. The 18th Corps was transferred to the First Field Army to participate in the liberation of the Great Northwest. In this way, the 18th Corps was transferred from the North China Field Army to the First Field Army, fighting across two field armies. Not only that, the 18th Corps also threw itself into the cause of liberation under the command of three marshals. The first is Xu Shuai's liberation of Shanxi, the second is The liberation of Lanzhou by Boss Peng, and the third is the liberation of the southwest by Boss He. Three different regions also mean that the 18th Corps, on the battlefield of liberation, has successively switched to the three theaters of operations in North China, Northwest China, and Southwest China. With such a rich experience, I am afraid that only the 18th Corps.
The third corps to fight across two field armies was the 19th Corps, and the commander of the corps was the famous tiger general General Yang Dezhi. The corps originally belonged to the North China Field Army, and its predecessor was the famous Yang Luogeng Corps. After the Battle of Pingjin, the 19th Corps was transferred to the northwest to participate in the Liberation of Lanzhou campaign, under the command of Peng Lao of the First Field Army.
Probably the 19th Corps did not participate in the battle to liberate the southwest, but the corps participated in the War to Resist US Aggression and Aid Korea. It was the only one of the three corps that spanned two field armies and fought in the war to aid Korea.
