In the twelfth year of Jianxing (234 AD), Zhuge Liang, the chancellor of the Shu Han Dynasty, cut wei for the fifth and final time. Due to the "turtle tactics" of his old rival Sima Yi, Zhuge Liang had the ability to reach the heavens and had no choice. In the autumn of that year, Zhuge Liang's illness was getting worse and worse, he arranged for the aftermath, handed over the soldier's charm to The Chief Shi Yangyi, and let him take full responsibility for the affairs behind him, and he also ordered that after the general Wei Yan was cut off, if Wei Yan did not obey the order, then it would not matter to him, you can retreat on your own.
We know that The long history Yang Yi and the general Wei Yan have always been at odds, and when Zhuge Liang was alive, he could reconcile in the middle, but he did not completely resolve the contradictions between the two of them. Now that Zhuge Liang had died of illness and the contradictions between the two had erupted in full swing, Yang Yi sent Ma Dai to behead Wei Yan, ending in Yang Yi's victory. Wei Yan was a battle-hardened general, and although Ma Dai was not bad, compared with Wei Yan, it was much worse, and the result was that Ma Dai killed Wei Yan. In the rendition, Ma Dai was ambushed by Wei Yan's side at the behest of Zhuge Liang, and at the critical moment when he shouted three times, "Who dares to kill me", he took a fatal knife from the back of his head and killed him, so in the history, how did Ma Dai kill Wei Yan? Does he have any purpose?
Personally, I think that Ma Dai killed Wei Yan out of his own selfish intentions and surrendered his name to Yang Yi, a patron. He was able to kill Wei Yan, who was stronger than himself, for the following three reasons, which were analyzed below.
First, the Manchu Dynasty supported Yang Yi, believing that Wei Yan was plotting rebellion.
After Zhuge Liang's death, Yang Yi, as the commander of the first army, sent Fei Yi to Wei Yan's army to investigate the situation, and learned that Wei Yan did not want to withdraw his troops, nor did he obey Yang Yi's command, so he led the army to retreat slowly. When Wei Yan learned of this, he was furious and led his own headquarters to travel day and night, rushing ahead of Yang Yi and burning the Pavilion Road. At this time, Yang Yi and Wei Yan both made a statement to the empress dowager Liu Chan, both saying that the other side was plotting rebellion, and the later lord could not make up his mind for a while and asked the minister of culture and military affairs for advice.
Dong Yun, the governor of the imperial household, Shi Jiangwan, and other ministers of culture and military affairs all believed that Yang Yi was a civilian official, deeply trusted by Zhuge Liang, the chancellor, and would not rebel, while Wei Yan did not dare to guarantee it. This was equivalent to the Manchu Dynasty's ministers of culture and military affairs who became Yang Yi's backing and isolated Wei Yan. Wei Yan lost the support of Manchu Wenwu and Liu Chan, and even if he defeated Yang Yi, it would not help. The Romance of the Three Kingdoms records the following:
Yan and Yi each rebelled, and in one day, Yu Tan was handed over. Later, the lord asked Dong Yun and Shi Jiang, the governor of the liufu, and Huan and Yun Xian baoyi were suspicious.
Secondly, Wei Yan's army was divided and disintegrated by He Ping (Wang Ping).
Although Wei Yan's army occupied a favorable position at the mouth of the Southern Valley, it took the initiative to attack Yang Yi's army. However, Yang Yi had the soldier charms left by Zhuge Liang, and the soldiers under him only recognized the soldier charms, believing that Yang Yi had inherited Zhuge Liang's mantle, followed Yang Yi correctly, and had the upper hand. Yang Yi sent he ping, a general no less than Wei Yan, to confront Wei Yan.
He Ping could not bear to kill each other, so he bitterly persuaded Wei Yan's army: "Gong died, his body is not yet cold, Ru Generation He dare Nair!" Unexpectedly, He Ping's words were very effective, and Wei Yan's headquarters also thought that his general was at fault, so he scattered and fled, not listening to Wei Yan's words.
In the end, Ma Dai took the timing very accurately, stepped forward at the critical moment, and killed Wei Yan.
After He Ping divided and disintegrated Wei Yan's army, he also could not bear to kill each other, so he did not kill his former colleague Wei Yan. After Wei Yan's army dispersed, he could only flee with his son and fled all the way to Hanzhong. Hanzhong was the old lair of Wei Yanzhen for many years, and it is estimated that there were generals and troops loyal to him. At this time, Yang Yi panicked, afraid that Wei Yan would make a comeback, so he sent a stunned Qingma Dai to pursue and kill Wei Yan. After the death of his cousin Ma Chao, Ma Dai has been tepid in the Shu Han army, following Zhuge Liang in the southern expedition to the north, and he has his figure every time he cuts Wei.
At this time, Zhuge Liang also died of illness, and if Ma Dai wanted to maintain his power, he needed to find a new patron. In the early stage of the fight between Yang Yi and Wei Yan, he looked at it intuitively. Now, Yang Yi had a very big advantage, and Wei Yan fled to Hanzhong like a lost dog. Everyone knew that Yang Yi had won and Wei Yan had lost. Therefore, Ma Dai decisively chose to obey Yang Yi's orders, hunt down and kill Wei Yan, and take Wei Yan's first rank as a surrender to Yang Yi. The relevant records in the Chronicle of the Three Kingdoms and the Biography of Wei Yan are as follows:
Yi sent Ma Dai to chase after him and bowed to Yi.
Summary: Although Ma Dai successfully killed Wei Yan, he became Yang Yi's confidant and was favored by Yang Yi. Unexpectedly, the later lord Liu Chan did not reuse Yang Yi, but reused Jiang Huan and Fei Yi, and only sealed Yang Yi as a Chinese military division with no real power. In the thirteenth year of Jianxing (235), Yang Yi was deposed as a commoner by the later lord Liu Chan because of his complaints, and exiled to Hanjia County. Yang Yi was exiled, not honest, and used more fierce words to write slander. Liu Chan, who had the best temper, couldn't bear it, so he sent someone to the county to arrest him. Yang Yi was very scared and committed suicide.
After Yang Yi's death, Ma Dai had no backing, and Bai killed Wei Yan, which can be described as a bamboo basket hitting the water. Ma Dai also led an army to attack Wei in 235 AD, but was defeated by the general Niu Jin, suffered heavy losses, and finally died without a disease.
