As we all know, Chiang Kai-shek ignored the Double Tenth Agreement reached by the Kuomintang and the Communist Party, brazenly launched an attack on the liberated areas where the Communists were located, and the civil war broke out, and in order to eliminate the Communists more quickly, Chiang Kai-shek carried out a series of operational plans. In 1947, Chiang Kai-shek launched a key attack on the liberated areas of Shaanxi, Gansu and Ningbo, and in order to take northern Shaanxi in one fell swoop, Chiang Kai-shek dispatched Hu Zongnan's 250,000 troops to attack here. In order to cope with the arrival of this force, the vice chairman of the Military Commission was ordered to go to northern Shaanxi to fight. 
It should be noted that the team led by Mr. Peng at this time was not a mature team, but the Northwest Field Army, which was formed by the joint efforts of various troops in northern Shaanxi, even if some garrison forces and various teaching brigades were all gathered together, the total strength was only 20,000 troops. It also means that this army was originally composed of peasants in northern Shaanxi and mountain people in Jinsui District, most of them originated here and were standard northerners, but the subsequent Northwest Field Army almost developed into a southern force. This statement is *** in the telegram, when reporting to ** personally stated, Mr. Peng said that most of his team is already Sichuanese, and has basically developed into a southern army, why is the team formed by northerners develop into a southern army. It is difficult to start with the expansion of the Northwest Field Army, the foundation of this army is relatively limited, and it is impossible to achieve large-scale expansion in the future, but the pressure is not inferior to that of any field army. 
Hu Zongnan's regular army, plus local troops, had up to 500,000 troops, threatening the security of the Northwest Field Army at any time, and under such circumstances, Mr. Peng always wanted to expand his team. However, the Shaanxi-Gansu-Ningbo region is too poor, and it is extremely difficult for the peasants to survive alone, and the expansion of the army is almost equivalent to wishful thinking. In order to alleviate the problem here, ** tried to send Chen Geng there, after all, this person is thoughtful and may be able to change the status quo of the Northwest Field Army. However, because Mao Fangxi decided to attack the hinterland of the Kuomintang, he could only leave Chen Geng behind and advance into the Central Plains with Liu Deng and others. Since he can't recruit troops on the spot and can't rely on the support of other teams, then Mr. Peng can only rely on himself to expand his military strength. 
Hu Zongnan's team became vulnerable under the tactical command of Mr. Peng, and the unique geographical conditions of northern Shaanxi made it more convenient for Mr. Peng to gradually consume Hu Zongnan's army with a small army. In a very short period of time, Mr. Peng caused as much as 1With the loss of 40,000 troops, Hu Zongnan could not change the situation even if he counterattacked with all his might. Of course, the Northwest Field Army will also have battle losses, and in order to solve this problem, Mr. Peng can only absorb prisoners into his own team. 
Hu Zongnan's group of troops replenished, most of them came from the rear of Sichuan, so these prisoners naturally had more Sichuan troops, and after they were slowly absorbed into the Northwest Field Army, they accounted for more and more of them, so Mr. Peng would only say in the telegram that his team was about to become the Sichuan army. So when there are more and more prisoners from the Kuomintang ranks, will Mr. Peng not be able to suppress it, this worry does not exist, Mr. Peng is not only good at operational command, but also a political commissar who is very good at political work, under his adjustment, these troops gradually resonate with the ranks of the People's Liberation Army, and finally willingly return to the Communist Party.
