At present, there are 14 regiments attacking our enemy, while our army has only more than 2000 people. You can't keep it. You should make decisive decisions and organize breakthroughs. Next, please ask the Chief of Staff to talk about the deployment of breakthrough operations. " Deng Ping pointed to a place on a large military map on the wall and said, "The breakthrough point is at the junction of Jiangxi and Hunan. Concentrate our existing forces, form a comparative advantage, take it by surprise, fight hard and tear a hole. In the past, frontier ministries should not be separated from the enemy. Stick to them, secretly deploy most of the troops, and prepare to participate in the breakthrough battle. I think I will lead the secret service company, machine gun company and mortar company to make sharp knives. After the gap is torn, the first regiment and the seventh regiment serve as the left and right wings respectively, forming a safe passage. The political commissar will lead the telephone team and the health team to escort all family members and the wounded and sick to pass quickly, and the commander will take four regiments to the temple for protection. " Peng listened and waved his hand again and again: "Wrong! No! I used to be here when I was a soldier in Xiang army. As a sharp knife and striker, you are not as suitable as me. " Deng Ping said firmly, "You are the leader of an army with great responsibility, and the future development of the Fifth Army will depend on you. In addition, there are so many patients and their families who need protection, which is an important task that Zhu Mao gave you when he went down the mountain! The military situation is urgent, don't argue any more. "

According to Deng Ping's deployment, Wu Gongjun rushed out of the tight encirclement, rejuvenating the country, raiding Du Yu and winning.

Three months later, Li Jinggangshan, the Red Fifth Army, passed by here, tears streaming down her face, and her hands clasped Peng tightly. Deng Ping wiped his eyes and said, "Commander, I have missed you and our troops every day for the past three months. Now I come back from my injury and report to you. " Peng said excitedly, "My broken wings have grown back!"

Peng was deeply impressed by Deng Ping's outstanding military talent and revolutionary spirit of being fearless in times of crisis and bravely shouldering heavy burdens.
