In history, Japan committed the most heinous crimes against the Chinese side, and japan "actively" participated in many wars of aggression against China; eventually the People's Liberation Army's War of Resistance Against Japan was launched, and China won many victories in the War of Resistance Against Japan. The Battle of Loess Ridge was the most exciting battle fought by the People's Liberation Army, the army led by the commander of the first division annihilated more than 900 Japanese troops on the enemy side, and also killed the lieutenant general, which was a commendable achievement, and the whole team was immersed in the joy of winning the battle, but commander Yang Chengwu looked worried, because he knew that the Japanese army would not be so good, in other words, the other side would avenge the lieutenant general with more powerful troops.
Sure enough, the Japanese army launched a retaliatory operation at the beginning of the same month, and a total of 20,000 people marched to the Jin-Cha-Ji camp to fight the People's Liberation Army to the death. When we saw that the other side was "agitated", the commander immediately ordered a retreat, and some of them covered the current retreat of others, and finally the Fuping area was unfortunately occupied by the Japanese army. Yang Chengwu led everyone to move to wolf's tooth mountain, and in the process all the soldiers seemed to be very lazy, it turned out that these soldiers were still immersed in the joy of the last big victory, and they were oblivious to a victorious battle, this was the best time for the enemy to take advantage of the void, and even more so that some people actually begged the people for food, and then the soldiers were "taught" by Yang Chengwu, in order to prevent the ups and downs of the soldiers' emotions, Yang Chengwu passed on the message through the instructor to everyone that they could borrow food from the people, but not take it.
After reminding everyone that their attitudes were much correcter, and they also knew the commander's good intentions, but the leader of the regiment did not seem to have been "woken up" yet. When the team marched to Nanguantou, they needed to spend the night, and the commander asked the regimental commander Song Yulin to inspect the situation nearby when determining that the vicinity was relatively safe, and the commander could predict that the Japanese side would definitely chase all the way over, so let Song Yulin strictly guard to prevent emergencies, and then Yang Chengwu left first. Song Yulin agreed to any request in front of the commander, but as soon as the commander left him, he took it upon himself to find a hidden place to take everyone to sleep, completely ignoring Yang Chengwu's worries about the situation.
In the middle of the night, the Japanese army did exactly as Yang Chengwu expected, they chased to Nanguantou and found the local PLA garrison, but Song Yulin was leading everyone to hide and sleep, and the local people did not find that the PLA also stayed overnight in the local area. When someone finally found out the abnormality the next day, Song Yulin was frightened and immediately rushed to Yang Chengwu to explain the situation, fortunately, the troops had been transferred in advance, otherwise they would all become the enemy's souls. The whole thing was the responsibility of Song Yulin, who did not lead by example, the headquarters was occupied by Japan, and Song Yulin was also dismissed from her post.
