In 1949, the whole army was reorganized, and the Northeast Field Army was reorganized into the Four Fields, and the 15th Corps was formed respectively. Each corps has three corps under its jurisdiction, and each corps has four divisions under its jurisdiction, with a strength of between 50,000 and 60,000 troops. Compared with other field armies, the four fields are strong and have high morale. Each corps in Siye is equipped with two very outstanding deputy commanders, they are: Chen Bojun and Han Xianchu of the 12th Corps;Li Tianyou and Peng Mingzhi of the 13th Corps;Huang Yongsheng and Liu Zhen of the 14th Corps;Hong Xuezhi and He Jinnian of the 15th Corps. In the 1952 rating, except for Peng Mingzhi, the other deputy commanders were rated above the rank of regular corps. So, why is Peng Mingzhi rated lower than others?
It is not difficult to see from the resume that Peng Mingzhi is an old qualification, he joined the party as early as 1925, and is the oldest of these deputy commanders. However, his experience was relatively tortuous. During the War of Resistance Against Japanese Aggression, he served as the chief of staff and regiment commander of the 115th Regiment of the 685th Division, as well as the commander of the Sulu-Henan Detachment and the brigade commander of the 3rd Division of the New Fourth Army. The 7 Brigade in which he was a member is a force with a long history, which dates back to the Nanchang Uprising. Peng Mingzhi is also a member of this force, and his leadership skills are also obvious to all. After the end of the Anti-Japanese War, he participated in the Northeast Campaign, and the 7th Brigade performed well, participated in the Battle of Xiushui Hezi and annihilated 5 enemy battalions, and also participated in the Battle of Siping. Despite his poor health, Peng Mingzhi insisted on directing the battle on a stretcher. After the battle, he was urgently sent to the rear to receive **.
For more than two years, he left the battlefield. Until the Liaoshen Campaign, he was transferred to the deputy commander of the 2nd Corps to assist Cheng Zihua in the battle. Later, he was transferred to the 13th Corps as the first deputy commander, and subsequently participated in the troops' advance in the central and southern regions, and participated in the famous Battle of Hengbao. After the war, he was sent to Beijing to engage in diplomatic work, where he held a diplomatic post for two years. However, due to poor health, he was forced to return to his home country to receive **. Later, he did not return to diplomatic posts, but turned to military work, taking the post of commander of the Hebei Provincial Military District. During this time, he was rated as a Quasi-Corps for his outstanding performance. Although he should have been awarded the rank of deputy regiment according to his position, the rating is not only based on his position, but also on his personal record and performance. Many generals served in the corps, but were eventually rated as deputy corps.
A few years later, due to health reasons, he switched to recuperation, and finally officially left his post in 1960. It can be said that he was one of the last retired generals of China's founding fathers.
