I read the Left Transmission ninety-six (627 BC) for thirty-three years of Lu Qigong

In the Battle of Kunshan, the Qin army was completely destroyed, and the strategy of the Qin state to expand eastward was almost devastated, and it is unimaginable that 400 years later, the Qin state is still unified along this road.

In the spring of this year (627 BC), Meng Mingshi's army rushed thousands of miles to attack Zheng Guo, passing through the north gate of the Zhou Wangdu, according to the etiquette system, except for the driver (the emperor) who drove the chariot, all other soldiers should take off their armor and parade to pay tribute to Wang cheng, but the Qin soldiers were extremely poorly disciplined, and the soldiers of the qin army only took off their helmets after coming down, and then ran two steps quickly to jump on the chariot, and the scene was chaotic. Seeing this scene, the young Wang Sunman said to King Xiang of Zhou: "The Qin army is frivolous and rude, and if it does not take the war seriously, it will definitely fail." ”

The Qin army entered the slippery country, encountered Zheng Guo's merchant Xiang Gao, who was preparing to sell cattle in Zhoudu, and Xiang Gao responded to the situation, falsely claiming that he was assigned by Zheng Guojun to come and treat the Qin army and send twelve cattle. Meng Ming took a look, Zheng Guo already knew his intentions, he must be ready for war, the sneak attack may not be successful, and there is no follow-up reinforcement in the protracted war, or retreat. The elder was far from being able to come in vain, and conveniently captured the slippery country, and then retreated westward. This is the famous string master.

At the same time that Xiang Gao coaxed the Qin army, he asked his companions to return to Zheng Guo to report the letter as quickly as possible, and after Receiving the report, Zheng Mugong sent someone to the residence of Qizi and others to check, these people had already tied up the salute (bundled load), the sharpness of the blade (Li Bing), the war horses were also fed (Mo Ma), Zheng Guo saw that What Xiang Gao reported was true, and expelled The Qizi and others.

Uncle Jian's divine prophecy must have the element of the appendage of the hereafter, but the sneak attack on Zheng Guo became a death, and the loss was so crisp, not only caused by the carelessness of Meng Mingshi, who led the troops, but also the strategic judgment of Qin Mugong was the main reason, that is, whether the Jin State would send troops.

Sending troops or not sending troops is also controversial in the Jin Dynasty. Luan Zhi proposed that Duke Wen of Jin had just died, and it was inappropriate to start a war with the Qin state, right? Xianxun said: "One day to indulge the enemy, several generations of troubles" (the opportunity must not be lost, the loss will not come again), Jin Xianggong decided to fight. So quickly gathered people and horses, and ambushed with Jiang Rong in Kunshan, on April 13, the Qin army entered the ambush circle, and the Qin soldiers who were like arrows in their hearts had combat effectiveness to speak of, the key was that they did not expect that the new king of the Jin State would launch a big battle?

The result was very sad, and the Qin army fled without a horse. Meng Mingshi, Xi Qishu, and Bai Yibing will be captured. Later, at the request of Duke Wen of Jin, Duke Wen of Jin, duke Xiang of Jin released the three of them back to the Qin state.

The Jin state can quickly organize an ambush battle, explaining: 1, the Jin state knew in advance that the Qin army passed through Kunshan Mountain, there was intelligence; 2, the Jin state was only decided to ambush after the Qin army was destroyed, and the troops gathered and reacted quickly; 3, the strong Qin army did not organize any effective counterattack, did not realize that the Jin congress launched an attack, engaged in the Hou Qin Mugong himself took the initiative to admit the mistake, the Qin state had misjudged in strategic understanding, and Uncle Jian was even better.
