In 376 AD, in the 19th year of Emperor Zhi's insistence on being emperor, Former Qin destroyed the last enemy state in the north, at this time, the north was basically unified by Former Qin, but the domestic Xianbei, Qiangyu and other ethnic groups were not sincerely submissive, and there were many contradictions.
A year before the destruction of the Daiguo, Wang Meng, the most trusted adviser of Jian Jian, fell ill and died, and before Wang Meng died, he had shown Jian jian the way to eliminate domestic hidden dangers first, and then plotted against the Eastern Jin Dynasty, however, after unifying the north, Wang Meng did not listen to Wang Meng's words, but quickly pointed the spearhead at the Eastern Jin Dynasty.
In 383, Jian Jian mobilized the strength of the whole country and began to conquer the Eastern Jin Dynasty, ordering Xiang Rong to lead Zhang Oyster, Liang Cheng, and Murong Chui to take 250,000 infantry cavalry as the forward, while he himself took more than 600,000 soldiers and 270,000 cavalry, followed by a million troops, and slaughtered the Eastern Jin Dynasty.
Soon, the vanguard troops under the leadership of Xiang Rong, they attacked Shouyang, the news spread to the Eastern Jin Dynasty, the Eastern Jin Dynasty junchen was in a panic, quickly sent Xie An's brother Xie Xuan as the commander, led the most elite Northern Fu soldiers in the Eastern Jin Dynasty to resist the Former Qin army, but unfortunately, the Northern Fu soldiers were only more than 80,000 people, even with the help of geographical advantages, it could not be the opponent of the Former Qin million army, right? The Eastern Jin Dynasty monarchs were helpless.
Hearing that the Eastern Jin Dynasty only had 80,000 soldiers and horses, Jian Jian laughed at the front and back, and also wanted to learn from the ancients to be a soldier who surrendered without fighting, so he sent the Eastern Jin general Zhu Xu to persuade him to surrender.
This Zhu Xu, the son of Zhu Tao of the Eastern Jin Dynasty and the Western Manchu Colonel, yizhou assassin Zhu Tao, was also a famous general of the Eastern Jin Dynasty, who rose to the rank of general of Yingyang by military merit, and when guarding Xiangyang in 378, Xiangyang was lost and was captured by Zhu Jian, but Zhu Jian admired Zhu Xu's loyalty and did not kill Zhu Xu, but let him do Du Zhi Shangshu.
This persuasion, of course, will go to the most appropriate ah, so Zhu Xu became a Former Qin emissary and went to the Eastern Jin Dynasty, but what Jian Jian did not expect was that this Zhu Xu, although he had been submitting to Former Qin for 5 years, still had his heart set on the Eastern Jin Dynasty.
After arriving in the Eastern Jin Dynasty, he immediately discussed with the main general Xie Xuan and others how to retreat from the enemy, and when he learned that Xie Xuan's people's strategy was actually unable to hold out, Zhu Xu was shocked and said to Xie Xuan:
If the Qin army's millions of soldiers arrive, how can we compete with them? The best thing to do now is to quickly crush the vanguard and demoralize them when they are not all there.
”。
Xie Xuan and others were deeply impressed, and finally decided, in consultation with the Former Qin army, whether they could be allowed to retreat and wait for the Jin army to cross the fat water and then fight a decisive battle, this proposal of the Jin army was opposed by most of the generals of Former Qin, but Jian Jian believed that the Jin army was half-crossing, which was the best time to attack, and agreed to the request of the Jin army to let the troops retreat.
The army suddenly retreated, and the soldiers under him had no idea what was happening, and Zhu Xu was overjoyed to see the situation and immediately shouted in the army:
The Qin army was defeated!
A stone stirred up a thousand layers of waves, the Former Qin army was in chaos, ordinary soldiers were like headless flies, running around, the Jin army took the opportunity to attack, Former Qin collapsed thousands of miles, and when it fled to Luoyang, there were only 100,000 million troops left, and Jian Jian wanted to cry without tears.
After this battle, Former Qin rapidly declined, and the Xianbei, Qiang and other tribes raised troops to rebel, and eventually, Murong Chong besieged Chang'an, and Jian Jian fled to Wujiangshan and was hanged by the Qiang leader Yao Cang at the age of 48.
