The Second Field Army during the Liberation War was formed after the victory at the Battle of Huaihai and was reorganized from the Central Plains Field Army. The newly formed Second Field Army had a total of nine regular armies. These nine armies were all liu shuai, commander of the Second Field Army, and a combat unit (referred to as the conventional army) commonly used on the battlefield. For example, in the Battle of the Crossing River, together with the Third Field Army, it broke through the Yangtze River defense line and marched into Jiangsu and Zhejiang. There are also battles to liberate Yunnan, Guizhou, Xikang, Sichuan, Tibet and other regions, and the nine conventional armies of Erye are all tiger and wolf divisions on the battlefield, attacking cities and pulling up villages.
Friends who may know history know that Yunnan was liberated by the 13th Army, the 14th Army, and the 15th Army, one of the nine conventional armies of the Second Field Army. Guizhou was liberated by the 16th Army, the 17th Army, the 18th Army, and other units of the Nine Conventional Armies of Erye. Chongqing, as the capital of Chiang Kai-shek, was the 12th Army of the Erye Ace, as well as the 11th Army, and the Tenth Army, under the command of Chen Xilian, the commander of the corps, liberated Chiang Kai-shek's capital Chongqing. Subsequently, the 16th, 17th, 18th, and 10th Armies of the Second Field Army, as well as other fraternal units, joined Chengdu to eliminate all the remnants of the Nationalist army and successfully liberate Chengdu.
In the Battle of Xichang, Erye's subordinates of the 14th Army, the 15th Army, the 18th Army, the 16th Army, and other units, in this battle, severely damaged Hu Zongnan's military group. Let Hu Zongnan, the king of the northwest who was once famous in the northwest region, abandon his troops and flee to Hainan alone on a special plane. The Southwest Campaign was basically over at this point, and soon after, the 18th Army, one of the nine regular armies of Erye, under the leadership of General Zhang Guohua, entered Tibet and liberated the Western Plateau. After the successful liberation of this land, the 18th Army was stationed in Tibet.
After the victory of the War of Liberation, the 12th Army and the 15th Army of the Nine Conventional Armies of Erye later participated in the War to Resist US Aggression and Aid Korea (the famous Battle of Shangganling was a brilliant record jointly created by these two armies in the battlefield of aiding Korea). The 16th Army and the 17th Army formed the Guizhou Military Region and participated in the suppression of bandits in the southwest, and later the 16th Army also participated in the War of Aid to Korea.
The 11th Army's military headquarters was transferred to Qingdao, Shandong Province, to form a naval base, and the 31st Division under its jurisdiction was incorporated into the 12th Army to participate in the War of Aid to Korea. The Tenth Army was formed into the Southern Sichuan Military Region, and the 29th Division under its jurisdiction was incorporated into the 15th Army. Soon after, the Tenth Army was reorganized into the Navy, several other divisions under it were transferred to other units, and the Tenth Army was abolished.
After the liberation of Yunnan, the 13th Army and the 14th Army remained on the border of Yunnan and Burma, taking on the heavy responsibility of defending the border. Among them, the 14th Army played an important role in guarding the southwestern border. It should be known that in 1950, the 14th Army was stationed on the border of Yunnan, and participated in the battles of suppressing bandits and counterinsurgency on the southwest border many times, and over time, the 14th Army accumulated rich experience in mountain jungle combat. Not only that, the 14th Army also participated in the 1979 Southwest Frontier Self-Defense Counterattack, which was the main force in this battle. It has made an important contribution to peace on the southwestern border. Therefore, the 14th Army is also an ace force that is best at mountain jungle warfare in the people's army, and is known as the Jungle Tiger Army.
The 13th Army also remained in Yunnan after the victory in the War of Liberation and took on the heavy responsibility of defending the border state. On the battlefield of liberation, the 13th Army was the Second Field Army, one of the nine regular armies, the main ace army, and its fighting style was very tenacious. After the founding of the People's Republic of China, the 13th Army, like the 14th Army, was one of the main forces guarding the border between Yunnan and Burma. He participated in the southwest banditry and counterinsurgency battles, including the border self-defense counterattack in 62 years and the border self-defense counterattack in 79 years, with the participation of the 13th Army. The 13th Army, which had long fought on the southwest border, mountains, plateaus, and jungles, also won the title of Tiger Army in the Mountains.
