Did Zhuge Liang behead Ma Su? Why do historians say he escaped?

Historians say it is not impossible that Ma Di ran away. Zhuge Liang valued Ma Su very much, and Ma Su was the younger brother of Zhuge Liang's brother Ma Liang. Zhuge Liang could not bear to kill Ma Su because of his emotions. Moreover, it was Ma Su's fault that the street pavilion was lost, but Zhuge Liang could not escape the blame. At that time, Zhuge Liang clearly knew the importance of the street pavilion, and knew that Ma Di had never led troops to fight before. Liu Bei also reminded Zhuge Liang before his death that Ma Di still needed to be observed and could not be used for much purpose. However, the always cautious Zhuge Liang was confused by Ma Su's superficial skills. He lost the street pavilion, delayed the battle, and had no choice but to retreat to Hanzhong.

Despite this, Zhuge Liang may not kill Ma Su. One reason is Ma Liang's relationship, and another reason is that Zhuge Liang knows that he should also bear greater responsibility. This is called a personnel error. Furthermore, this was the first time that the Shu Han sent troops to Qishan. For Zhuge Liang, who was determined to regain the Han Dynasty, this failure was nothing. The worst he could do was to start over again. If Ma Di was killed because of this mistake, he would not be able to bear it. Even if he is reluctant, it is very possible to secretly help Ma Su escape. This shows that Zhuge Liang truly appreciates Ma Di and truly cares about his friendship with Ma Liang. It also proves that Zhuge Liang's confidence in attacking Wei is unique. He feels that he will definitely be able to conquer Wei. Even with this failure, He is also full of confidence.

It was indeed an accident that Ma Su was the street pavilion. The situation of the Shu army was very good at that time. If it were any other general guarding the street pavilion, he would never have lost the street pavilion. It is a pity that Zhuge Liang made the mistake of underestimating the enemy. His emotions also gained the upper hand and he appointed Ma Su, but it was a pity that Ma Su, who he regarded as a great leader, was so self-righteous and self-righteous. Even though his deputy general Wang Ping tried his best to persuade him, Ma Su still went his own way and would not give up until he reached the Yellow River. He was like a spy placed by Wei in the Shu army, preparing for Wei's victory at every turn.

Zhuge Liang's regret can be imagined. Ma Di may be gritting his teeth because he hates his failure, but the matter is already at this point, and it is meaningless to say more. He would never use Ma Su again, and he didn't even want to look at him again. Thinking of his good friend Zhang Liang, Zhuge Liang could only sigh, and in the end it was very likely that he would let Ma Su run away. According to historical records, there are several endings about Ma Su. It is said that he died in prison, some said that he was beheaded, and some said that Ma Su escaped. But no matter which ending it is, Ma Su is definitely a big joke. It's better to be down-to-earth as a person. Rhetoric will only harm the country and cause problems.
