1, the battle of Guandu.
The two sides of this war are Cao Cao and Yuan Shao, and it is one of the most famous battles in history. Cao Cao defeated Yuan Shao with one tenth of his troops, thus unifying the north and laying the foundation for the tripartite confrontation among the three countries. In fact, at the beginning of this campaign, Cao Cao was on the backward side, that is, he was about to fail because of lack of food and grass and insufficient troops. Just as Cao Cao was preparing to withdraw his troops, a little thing happened to Yuan Shaofang, that is, Yuan Shaofang had an argument with his counselor Xu You. Xu You ran to Cao Cao's barracks in a rage and told Cao Cao where Yuan Shao was weakest. Cao Cao then attacked overnight, captured this place and defeated Yuan Shao in one fell swoop. The reversal of the battle was caused by a small matter.
2. Battle of Red Cliffs.
The alliance between Battle of Red Cliffs Cao Cao and Sun Liu. At that time, Cao Cao was outnumbered and prepared to destroy Liu Bei and Sun Quan in one fell swoop, forcing Liu Bei and Sun Quan to form an alliance, but he was still no match for Cao Cao. On the day of the battle, the east wind suddenly hung, and Zhou Yu decided to attack it with fire, and went down with the wind and defeated Cao Cao. Because of a small wind, the war situation reversed.
3. The Battle of Yiling.
The warring parties in the battle of Yiling were Liu Bei and Lu Xun. Liu Bei launched this campaign to avenge his younger brothers Guan Yu and Zhang Fei. Lu Xun, who played for Liu Bei at first, lost many camps. However, Lu Xun observed that the weather was dry recently, so he released Yamakaji, and Liu Bei's barracks were all stationed in the mountains, so they were destroyed by fire.
These are a few examples of turning the tide because of a small matter. Of course, there should be many such examples in history, from which we can get some enlightenment, that is, never give up until the last moment, because you don't know what will happen in the end.
