If Wu Sangui had not participated in the war, could Li Zicheng have successfully challenged Dorgon alone

Many people are not familiar with Li Zicheng and Dorgon. Let’s follow the history encyclopedia editor to appreciate them together.
Zu Kuan, the servant of Zu Dashou, was able to beat Li Zicheng into a pure fool. Do you think Li Zicheng can beat up Dorgon?
Zukuan had only 3000 soldiers, and Li Zicheng, Zhang Xianzhong, and Gao Yingxiang surrounded and beat them up together. It was not that Zukuan had taken them away, but he himself had only 3000 soldiers and killed 4600 enemy soldiers.
How to one-on-one? If Li Zicheng is defeated by two men and two horses, and each leads troops to charge into the battle, Dorgon wins.
There is no comparability at all. In that era, Li Zicheng’s troops were the ones with extremely poor combat power. Even if they entered Beijing, Liu Zongmin still referred to himself (himself and Li Zicheng) as “bandits”, meaning bandits.
He was able to defeat Beijing because most of the generals he could defeat in the late Ming Dynasty were killed by Chongzhen (including the example just given by Zu Kuan), and even the political enemies of Chen Xinjia, Sun Chuanting, and Lu Xiangsheng in the civil service system couldn’t bear to see them die. Who was foolish enough to give Chongzhen an idea. Soldiers, not to mention their salaries, are good enough to have food to eat. Even firearms are terrible, which is why Li Zicheng can take advantage of them. When Ming Tingzhen was able to make a move, Li Zicheng’s predecessor was killed, and he was also thrown away like a dog.
If the Ming army had not focused all their attention and superior forces on the decisive battle outside the Great Wall, neither Li Zicheng nor Zhang Xianzhong would have survived.
Taking Qin Wang as an example again, it is a good thing that Zuo Liangyu received the news too late and did not come. He may not have come to save Chongzhen. If Zuo Liangyu didn’t get angry and did something good, it was considered lucky. If his anger was even stronger, he would have directly taken Beijing and saved the driver? That’s really interesting.
Tang Tong has arrived, and Chongzhen has already cut off his own life path at least three times. Perhaps Chongzhen is worried that he cannot be killed alive, so he sent eunuch Du Zhizhi to supervise Tang Tong’s army. Tang Tong attacked in front of him, and Du eunuch opened the city gate for Li Zicheng. Why bother attacking him? Why not surrender.
With the enrichment and updating of historical materials over the years, we can roughly calculate the military strength.
Wu Sangui has over 50000, of which just over 20000 are from the Guanning army.
The troops led by Li Zicheng, apart from dispersed garrisons, will never have more than 60000 soldiers participating in the Battle of Shanhaiguan.
The troops led by Dorgon, Wu Sangui requested 100000 soldiers, but Dorgon only brought 60000 because he felt it was time for the day and could not use 100000 people to fight anyone.
Although Wu Sangui and Li Zicheng had been fighting for a day when Dorgon entered the battlefield, there was still a huge gap in combat power from the fact that Ajige’s two charges completely dispersed Li Zicheng’s army. However, Dorgon did indeed take advantage of Li Zicheng, which cannot be denied.
After hastily ascending to the throne in Beijing, Li Zicheng began to flee, which meant that he did not want to confront the Qing army led by Dorgon again. There was only one reason, and he could not defeat them. Thinking about Li Zicheng’s “unyielding” tactics, it can be said that the more he was beaten, the more he refused, and the more he was beaten, the more he became happy. How could he not dare to accept the attack when he met with Ajige and the other two? It seems that in Li Zicheng’s heart, he still has points for his combat power.
