Zhu Yuanzhang had left an ace army, why didn't Zhu Yunjiao use it in the Battle of Jingnan?
Zhu Yuanzhang, as the founding emperor of the Ming Dynasty, was wise and wise, and made thorough preparations for the succession of his heir Zhu Yunjiao before his death, but Zhu Yunjiao was useless and failed to live up to his grandfather's painstaking heart, and even the ace army prepared for him by Zhu Yuanzhang did not have time to use.
After the death of Zhu Yuanzhang in the Ming Dynasty, the emperor was located in the emperor's grandson Zhu Yunjiao, and within two years, Zhu Di, the fourth son of Zhu Yuanzhang, the King of Yan, launched the famous "Battle of Jingnan" in history and attacked the city of Nanjing, resulting in Zhu Yunjiao's life and death being unknown, and Zhu Di successfully usurped the throne.
The reason for the "Battle of Jingnan"
Zhu Yuanzhang's son Zhu Diwen (朱棣文韬) was a martial artist with great military prowess and great military achievements, and his seniority was much stronger than Zhu Yuanzhang's grandson Zhu Yunjiao, and he was more suitable for the emperor's position, but Zhu Yuanzhang was doing his own thing and let Zhu Yunjiao inherit the throne. So much so that Zhu Di and Zhu Yunjiao had a conflict.
The emperor's grandson Zhu Yunjiao succeeded to the throne, and was known as Emperor Jianwen. Zhu Yunjiao was proclaimed empress, and seeing that the power of the king of the clan was so great, cutting the clan became the one thing That Zhu Yunjiao wanted to do most.
At the instigation of The Soldier Shangshu Qi Tai and Tai Changqing Huang Zicheng, Zhu Yunxiong wavered, and finally vigorously cut the Jianwen Emperor of the clan to support Huang Zicheng, and later abolished the titles of five princes.
The Xiang king Zhu Bai was humiliated and set himself on fire to protect his family; Zhu Yu, the king of Qi, was placed under house arrest in Nanjing; and Zhu Gui, the acting king, was placed under house arrest in the fiefdom of Datong. Zhu Yu ( 朱楩 ) , the King of Min , was deposed as a Shuren and moved to Zhangzhou.
Due to the intensification of contradictions in the imperial court, the king of the clan and the imperial court began to break with each other, and at this time, the most powerful King of Yan became the true head of the clans, which was the fuse of the Battle of Jingnan.
"The Battle of Jing"
When Zhu Yuanzhang was in power, he feared that the powerful subjects would usurp power, stipulating that the king of the domain had the right to move the central government to demand the side of the traitor and raise troops to the side of the Qing emperor, and he said in the "Ancestral Training of the Emperor Ming": "There is no righteous subject in the dynasty, and there is a traitor within, and he will raise an army to rebuke him, so as to the side of the Qing king." Zhu Di used this as an excuse to refer to Qi Tai and Huang Zicheng as traitors, and he had to be reprimanded, and called his actions "Jing Difficulty", that is, the meaning of calming the disaster. Therefore, Zhu Di's slogan in the Battle of Jingnan was "Qing Jun's Side, Jingguo Difficulty".
The mysterious ace army unit that Zhu Yuanzhang left to Zhu Yunjiao
At that time, Zhu Yuanzhang had long thought that after his death, someone might rebel, and in order to prevent such a thing, he specially left a mysterious army for Zhu Yunjiao, which was the 300,000 Mu family army guarding the town in Yunnan. Why was this army deeply trusted by Zhu Yuanzhang?
Mu Ying, the leader of the Mu family army, was an orphan who was later adopted by Zhu Yuanzhang and recognized as a righteous son. From an early age, he followed Zhu Yuanzhang's side, who regarded him as his own child, taught him to read and write, and taught him how to lead soldiers to fight.
After Mu Ying grew up, he made many military achievements, and Hongwu was named the general of Zhenguo for three years, and later he was in charge of the world's soldiers and horses, and was deeply valued by Zhu Yuanzhang. Later, Mu Ying quelled the rebellion in Yunnan and has been guarding Yunnan ever since. Mu Ying and Zhu Yunjiao's father Zhu Biao were friends of life and death, and after he heard the news of Zhu Biao's death, he was very sad, and finally even died of excessive sadness. Mu Ying's son Mu Sheng also lived in Nanjing since he was a child, and he was deeply favored by Zhu Yuanzhang, and had a very good personal relationship with Zhu Yunjiao, which can be said to be a friend of life and death. After Zhu Yunjiao succeeded to the throne, he immediately made Mu Sheng the Marquis and asked him to lead his troops to Yunnan to suppress the rebellion and guard Yunnan.
Why didn't Zhu Yunjiao use this powerful Mu family army
This is related to the ability of Zhu Yunjiao, who misjudged the situation and believed that there was no need to use the Mu family army. Zhu Di challenged Zhu Yunjiao, and in terms of strength, Zhu Di had no chance of winning at all. Because Zhu Di was a local antagonist center, although he had 100,000 troops and horses under him, even if he expanded his army, it was only 200,000, and Zhu Yunjiao's soldiers reached more than one million, so Zhu Yunjiao's advantage was very obvious. Therefore, Zhu Yunjiao believed that the King of Yan hit the stone with an egg, so that he misjudged the situation and did not mobilize the ace army.
The second was to blindly believe in Li Jinglong and did not use the Mu family army in time. Because of his relatives, Zhu Yunjiao has great trust in Li Jinglong, who has no talent and is disloyal. When Zhu Di attacked Nanjing, Li Jinglong could have defended for a while, but Li Jinglong ordered the city gates to be opened to meet the King of Yan, which made Zhu Yunxiong completely hopeless of defeat and victory. Zhu Yunxiong did not expect that Li Jinglong would be defeated so quickly, Zhu Di's army would invade the capital so quickly, and he simply did not have time to mobilize the Mu family army guarding Yunnan. Because he knew that the Mu family would definitely help him, he fled to the southwest after leaving the palace, just to let the Mu family protect himself.
In the end, Emperor Jianwen simply did not have time. From the time Emperor Jianwen turned from strong to weak, to the Yan King's capture of Nanjing, it took only more than a month. In this way, even if Emperor Jianwen wanted to rescue the Mu family army 4,000 miles away, it was obviously beyond the reach of the whip. In fact, looking at the entire "Battle of Jingnan", Emperor Jianwen's failure did not lie in the existence of a Mu family army, but mainly because of his improper employment.
