Collusion Full of people does not exist. Even the convicted Chongzhen is very clear about this - if he colluded with Manchus, why would he still fight to the death to defend Beijing City ? By watching from the wall, the Jurchen soldiers are likely to break through Beijing. Not to mention that he was with the Jurchens.
According to the " Ming History ", officials in the court held a crime for Yuan Chonghuan, with two charges: "being good at peace talks" and "specially killing the general." From these charges, it can be seen that Ming Dynasty did not convict Yuan Chonghuan of "traitoring the country": If he colluded with Manchus and surrendered to Manchus, what would he do to "better peace and contention"? "Peace discussion" is a matter between the enemy and us. Can we still "peace discussion" with ourselves?
In fact, these crimes are reasonable: "Master" Mao Wenlong is a general appointed by the court, and he is not an official of you Yuan Chonghuan. What power do you have to kill him? To negotiate peace with the enemy country is only the decision-making of the court, and it is not something that a former commander-in-chief can make the decision.
As Yuan Chonghuan, these charges are not entirely slander, and they are more or less authentic. However, after killing Mao Wenlong, Chongzhen also agreed to Yuan Chonghuan's request to increase military salaries, which was to affirm Yuan Chonghuan, at least he would "not be investigated." It was certain that if we pursued it a year later, was the court going back on its word? The matter of peace talks is just an intention, and to a certain extent, Yuan Chonghuan used "peace talks" as a delaying strategy, and no facts were formed.
Overall, these two charges are suspected of "surrendering the situation" and "rebounding one's words". So when Chongzhen killed Yuan Chonghuan, he was detained as a charge of "conspiracy to rebel". When it comes to "conspiracy to rebel", it means being unforgivable. As for whether or not "conspiracy" or how far it is, it is really vague.
In fact, Yuan Chonghuan's biggest problem is not "conspiracy to rebel", "unfairly kill", "peaceful discussion", etc., but rather dereliction of duty: as the commander-in-chief of the front-line enemy who specializes in defending the Jurchen soldiers, he let the Jurchen soldiers run to the capital to attack. This is not a dereliction of duty, what is it? Leading troops to rescue and rescue is not only his duty, but also his merits and demerits and the loss of the sheep.
Can your newly established "function" make up for the past "passes", only Chongzhen has the final say. If Chongzhen was more generous, tolerant and confident, he could have blamed Yuan Chonghuan while continuing to reuse him. Try and pull, rub horseshoe three times, and slap a sweet date again. These folk sayings have always been the art of leaders.
However, the "Tartar soldiers" besieged the capital, causing too much psychological oppression to Chongzhen, and he could no longer trust Yuan Chonghuan. Not only does he distrust, but he is also extremely disgusted. If he hates it to the point of being "universal", he will only die.
A general with shortcomings and weaknesses can only control it properly and let him play the greatest role when he meets a very wise and confident emperor.
Unfortunately, Chongzhen was neither wise enough nor lacked self-confidence. He is destined to be uninherent with "tellers with shortcomings".
