The story of "one blow".
In the tenth year of the reign of Lu Zhuang (684 B.C.), the Duke of Qi Huan sent troops to attack the Lu State because the Lu State had supported his brother Gongzi to fight for the throne, and the two sides launched a fierce battle in the long spoon of the Lu State. At that time, Qi was strong and Lu was weak, but because Cao Di had an accurate analysis and grasp of the situation of Lu before the war, and Cao Di was able to grasp the timing of counterattack and pursuit well after the war began, Lu defeated Qi instead, making this battle a famous example of a weak country defeating a strong country in the history of ancient Chinese warfare.
[sic] the public rode with it, and fought in the long spoon. The general drummed and said, "No." Qi people three drums, said: "Okay." "The division is defeated. The general galloped and said, "No." Looking down at it, he looked at it and said, "It's okay." Then he chased the division.
Both grams, the public asks why. He said: "Husband fights, courage also." One blow of strength, then decline, three and exhaustion. He did his best to make money, so he restrained it. The husband is a big country, unpredictable, and afraid of ambush. I regard it as chaotic and hope that it will be unstoppable, so I will chase it away. ”
Zhuang Gong and he sat in the same chariot and fought at the long spoon. As soon as the two armies met, Zhuang Gong was about to beat the drum and march. Cao Di said: "No. Qi Jun beat the drum three times, and Cao Di said, "It's okay." "The Qi army was defeated. Zhuang Gong wanted to chase after the military vehicles. Cao Di said: "No. He jumped out of the car to inspect the wheel traces of the Qi army, and then boarded the car and held the crossbar in front of the car to watch the defeat and retreat of the Qi army, and said, "It's okay." So he pursued the Qi army and drove them out of the border of Lu.
After winning the battle, Zhuang Gong asked why he commanded like this. Cao Di replied: "Fighting a war depends on courage. The first time the drum was beaten, the soldier's courage was greatly boosted, the second time the drum was beaten, the courage was lost, and the third time the drum was beaten, the courage was all over. The enemy's courage was over, and the courage of our army was strong, so the Qi army was defeated. The situation of the great power is elusive, and it is afraid that it has an ambush. I saw their cars in confusion and saw their flags falling, so I pursued them.
