Reproduce an example of a crushing defeat

The Battle of Feishui in August 383 is a famous example in the history of China. Eighty thousand soldiers participated in the Eastern Jin Dynasty, with five thousand casualties; There were 870,000 troops in the former Qin Dynasty, but only 654.38+10,000 people fled back after defeat. Fu Jian, the former Qin emperor, was also wounded by an arrow (in 385, he was captured and killed by the rebel army). The pre-Qin Dynasty, which had absolute superiority, lost to the Eastern Jin Dynasty, and the country declined and perished. The northern nationalities broke away from the pre-Qin rule and split into several countries or regimes, such as post-Qin and post-Yan. The Eastern Jin Dynasty took advantage of the Northern Expedition to push the border from the south of Huaihe River to the front of the Yellow River, and in the next few decades, it was protected from foreign invasion.

The Main Causes of Fu Jian's fiasco in Pre-Qin Period

Arrogant, subjective and arbitrary, not listening to dissuasion, rushing to war;

Internal instability, disagreement, confusion, and floating people's hearts;

If the front line is too long and the troops are scattered, the shed length will be short and there will be no coordination.

The first battle was frustrated and lost confidence;

Do not touch the military situation, retreat at will, and make a mess;

I don't know about the espionage activities of Zhu Xu and others, and I am in a passive position.

The winning factors in the Eastern Jin Dynasty

Don't be chaotic in times of crisis, and calmly respond to the enemy;

The monarch and the minister are in harmony, and the soldiers use their lives;

The Lord will be able and the command will be certain;

Grasp the enemy's situation and know yourself;

Foot soldiers, one is ten;

Use the right time and place to give full play to one's special skills;

Break the enemy in the first battle, defeat its soldiers and boost morale;

Inspire the enemy with wisdom, lure him into chaos, and take advantage of the gap to cover up and kill him;

Implement strategic pursuit and expand the results in time.

The key to the victory of the Eastern Jin Dynasty was Zhu Xu, who fought in Xiangyang in 379 and surrendered to Fu Jian. The Eastern Jin Dynasty obtained the pre-Qin military information through Zhu Xu: Fu Jian left the main troops in Xiangcheng (Shenqiu, Henan Province) and only took 8,000 light riders to Shouyang to join the 300,000 troops at the front. When Fu Jian sent Zhu Xu to surrender the generals of the Eastern Jin Dynasty, Zhu Xu privately revealed to Xie Shi (the fifth brother of Prime Minister Xie An): "If Qin Jun has reached the front line, it is really difficult to compete; Qin Jun has not been gathered by various routes, so we should attack quickly; If they can beat their forward troops, they will lose morale and eventually break them. "

So Xie Shi sent Xie Yan y m: n (the second son of Xie An) to select 8,000 warriors from the northern government soldiers (composed of lean northern immigrants, trained for seven years, with one as ten) to tide over the challenge of fertilizer and water. When Qin Jun retreated a little, Zhu Xu shouted after the battle of Qin Jun: "Qin Jun is defeated!" ! So Qin Jun ran away. Zhu Xu took the opportunity to return to the Eastern Jin Dynasty, awarded General Long Xiang and other important positions, and defeated Xiyan again.
