During the War of Resistance Against Japanese Aggression, General Yang Chengwu fought behind enemy lines for many years and had his own experience in dealing with the Japanese army. An incident in 1940 made him highly praised by Nie Shuai, and he has been deeply valued since then. General Yang's wisdom and courage in this battle, calmly leading a team of 200 people to safely evacuate from the encirclement of tens of thousands of Japanese troops, can indeed be said to be a miracle.

At that time, Yang Chengwu's troops were fighting behind enemy lines in North China, but they encountered a siege by the Japanese army around The Wolf's Tooth Mountain. After the contact, Yang Chengwu found that the enemy's reinforcements were more than 10,000 troops, so he immediately decided to leave the area to avoid major losses. In order to ensure the withdrawal of large troops, it is necessary to have a part of the troops stay and negotiate with the enemy to buy time. But what was surprising was that Yang Chengwu actually used only one company of people to take charge of such a difficult task, and he himself and the division cadre organs also broke through behind this small unit, which was undoubtedly very risky, and it could even be said that he died nine times.
It turned out that Yang Chengwu's decision was based on it, he analyzed the terrain and climatic characteristics of the battlefield, and thought of this adventure but may reap miraculous results. Moreover, the company that was left with the task of blocking the attack was not an ordinary company, and Yang Chengwu arranged for the guard company with the strongest combat effectiveness in his entire division. He asked the guard company to take advantage of the enemy's unstable position, and more than 200 fighters divided into three squads, from top to bottom, from the top of the hill to launch a powerful attack on the enemy. Because there was heavy fog in the mountains, the enemy was in the lowlands, and when he heard the shouts of killing that spread across the mountains, it was impossible to tell how many troops the Eighth Route Army had for a while. In the face of our soldiers who swarmed down from the top of the mountain, the Japanese army, which has always been known for its well-trained training, was a little flustered, and many people were killed in the chaotic ranks. The guard company managed to punch a passage into the ravine, temporarily leaving the Japanese not far behind.
However, after all, the Japanese army had rich combat experience, and after the initial melee, it immediately meant that the intensity of our army's gunfire was low, and it was not a large force. After stabilizing, the Japanese army began to encircle our guard company and division headquarters from the left and right sides with the help of numerical superiority. The number of Japanese troops is large, dozens of times that of our army, and there are Japanese troops before and after this time, and Yang Chengwu immediately made new arrangements according to the changes in the situation. Divide the existing troops into two routes, one to the north of the Jiulian Mountain, and the other as a suspect, first attack in the opposite direction of the Jiulian Mountain, attract enemy fire, ensure that the division headquarters has enough time to go up the mountain, and after a successful breakthrough, turn back to the Jiulian Mountain and join the division headquarters.
Sure enough, as Yang Chengwu expected, all of them were attracted by the second part of the fighters who protruded from the ravine. The division headquarters was able to calmly move to Jiulian Mountain, and because the fog in the mountains was thick, the enemy army was too heavy, and the pursuit speed was not as good as that of our army's breakthrough squad, so after marching for more than thirty miles to shake off the enemy, the second squad successfully reached Jiulian Mountain at noon the next day and achieved a full breakthrough! Nie Shuai commented on Yang Chengwu's breakthrough action afterwards, "In the face of danger, not chaotic, well-deployed, is a brave and strategic tiger general!" ”
