If you talk about the military generals of the Three Kingdoms, the most regrettable thing is that it is forbidden.
Yu Forbidden Wenze followed Bao Xin during the Yellow Turban Rebellion. Bao Xin was a loyal fan of Cao Cao, and he had long seen that he was not an ordinary person, and when Cao Cao first started his army, he responded positively.
When Liu Dai died in Battle of Yanzhou, Bao Xin actively plotted to welcome Cao Cao as Yanzhou Pastor, and At this time, Yu Ban naturally followed Cao Cao's account.

Unfortunately, Bao Xin was too real, and in order to save the old Cao Cao, he died on the battlefield, leaving Yu Ban alone in cao camp to shine.
At this moment, Cao Cao's foreign name will be banned except for Lejin.
Yu Banwei re-acted and followed Cao Cao in his southern expedition to the north. When he attacked Xuzhou, he worshiped Chen Duwei; when he conquered the Yellow Turban Liu Pei, he moved to Pingyu Lieutenant; when Zhang Xiu was in rebellion, he was given the title of Marquis of Yishouting because of the rebellion of the whole army and the rebellion; later, when he attacked Yuan Shao, he was also worshiped as a partial general.
Yu Ban was deeply trusted by Cao Cao, and after entering the vanguard, after retiring from the palace, he was moved to the left general due to his merits, and he was crowned with Zhang Liao, Le Jin, Zhang Guo, and Xu Huang.
If according to seniority, only he and Lejin are old qualifications.
Zhang Liao first followed Ding Yuan, then Dong Zhuo, and then Lü Bu, until Cao Cao defeated Lü Bu and followed Cao Cao.
Zhang Gao first followed Han Fu, and later submitted to Yuan Shao, waiting until Cao Cao settled jizhou before throwing himself into Cao Cao's account. The same is true of Xu Huang.
Therefore, for Cao Cao, Yu Ban was a great general of the humerus who suffered together. Especially in the early days, Lao Cao's good brother Zhang Mi betrayed and colluded with Chen Gong and Lü Bu to steal the family successfully, almost leaving Cao Cao without a place to stand.
During this period, those civilian and military generals who did not abandon them were all precious to Cao Cao, so there was a later Cao Cao said, I know that it is forbidden for thirty years. This word "knowing" is not only a one-sided gift of knowing, but also the meaning of knowing each other.
The martial generals mixed up to this point can be regarded as meritorious achievements, and if there is no accident, Cao Wei's meritorious deeds will have a heavy stroke.
But fate seems to have made a joke with Yu Ban again. In the twenty-fourth year of Jian'an, that is, in 219 AD, Liu Bei killed Xiahou Yuan at the Battle of Yangping Pass and captured Hanzhong.
Guan Yu, a former general in Jingzhou, also actively forged ahead, leading his troops to attack Cao Ren and besieging Him at Fancheng.
Therefore, Cao Cao sent his confidants to the forbidden and led 30,000 people of the Seventh Army to Fancheng to help.
Prohibited
Who thought that fate would be so impermanent, and when Yu Ban opened his position outside Fancheng and was ready to break Guan Yu's wrist, the sky was not beautiful, and the heavy rain fell for several days in a row, causing the Han River to soar, the river embankment to overflow, and the flat water to be several inches deep. The Seventh Army led by Yu Forbidden was all submerged, and Guan Yu took advantage of the situation to cover up and win a great victory.
In the Romance of the Three Kingdoms, the flooding of the Seventh Army was caused by Guan Yu's water storage, but the history records that this was a natural disaster, which happened to be encountered by the unlucky child yu Ban.
Sima Yiyun: Forbidden waiting is lost by water, not lost by war.
Jiang Jiyun: Yu Ban and others are lost by water, not the loss of war attack.
Wang Xinyun: There is no one hundred battles in the world, the general who has won every battle, forbidden to meet Linyu, defeated by Guan Mou, not ashamed.
According to the above-mentioned people, it can be known that the failure of Yu Ban was indeed caused by natural disasters.
And where Yu Forbade suffered was that he surrendered to Guan Yu. In fact, at that time, surrendering to save his life was not a very bad thing, Guan Yu had not sat in the Hanshou Pavilion Marquis.
But there is no harm without comparison, and Pound, who has just returned to Cao Cao for a long time, does not know why he can't think of it, and he has to fight to the death and become famous.
Pang De was originally a military general under Ma Teng, but later followed Ma Chao, and after Ma Chao surrendered to Liu Bei, he was subdued by Cao Cao, who broke hanzhong.
Until Fan Cheng's death, Pound's days with Cao Cao were less than a fraction of the forbidden.
So in contrast, Yu Ban's surrender became very glaring at this moment.
Lao Cao couldn't help but sigh, I know that the prohibition has been forbidden for thirty years, what does it mean to be in danger, but it is not as good as Pound's evil!
Although it was shameful to say that apostasy was shameful, Yu Ban finally saved his life, and it was good to live and die in Liu Bei's place.
However, fate wanted to trick him, and Guan Yu achieved brilliant results in the Battle of Fancheng, but he was immediately killed by Xu Huang, who rushed to the scene, and later stolen by Sun Wu and died of depression.
At this time, Yu Ban became a prisoner of the second stubble and was taken back to Jiangdong. Although he is still a prisoner, he is not easy to say, and his value is falling.
Cao Cao and Yu Ban
But it is better to die than to live, where to be a prisoner is the same, life must continue is not.
It's just that the joke of fate continues. After Cao Cao's death, his son Cao Pi ascended the throne as emperor, and Sun Quan repeatedly decided to call himself the younger brother of The Domain, and sent Yu Ban back with him.
At this time, Yu Ban was already white-haired and had become a dying old decay, and when he saw Cao Pi weeping, he had mixed feelings.
Cao Pi had just ascended to the throne, and Yu Ban had made great contributions to Cao Wei, and it was not good to turn his face in person, so he was kind and relieved, asking him not to pay attention to everything, and finally he was named a general of Anyuan.
It's just a set of Cao Pi in front of his face and a set behind his back. First find someone in the mausoleum house of Gaoling, paint a mural of Guan Yu attacking Fancheng, Pound De swearing to fight to the death, and begging for forgiveness on his knees, and then let Yu ban to go to Gaoling to worship.
As an emperor, Cao Pi's practice was really a bit of a small family. After Yu Ban saw the mural, he was ashamed and indignant, did not breathe a breath, fell ill and died, and a generation of famous generals came to an end.
Throughout yu ban's life, the first half of the way galloped on the battlefield, the name of the world, the second half of the bend, The end of the Fock.
However, his failure was not the sin of using soldiers, but the death of heaven. When the historian wrote the biography, he did not criticize him too harshly, but put him side by side with Zhang Liao, LeJin and others to express his merits.
But on the whole, it is still a pity, and the point of surrender is a pain that Yu Ban can never erase.
