In order to rescue Cao Ren, Cao Cao sent Yu Ban and others to support, but was flooded by Guan Yu of the Seventh Army, the general surrendered to Ban, Pang De was killed, and Guan Yu shocked Huaxia.

【Flooded Seventh Army】

In order to deal with Guan Yu, Cao Cao sent Yu Ban and others to assist, but he was defeated, Yu Ban surrendered, and Pang De was killed.

Cao Cao was in Chang'an at the time, and after learning that Cao Ren was besieged in Fancheng, he sent Yu Ban to assist Cao Ren in his fight against Guan Yu. As a result, in the autumn, it rained heavily, the Han River flooded, the water depth of the flat land was several zhang, and the seven armies under Yu Ban were submerged. Guan Yu approached the attack on a big ship, Yu Ban had to surrender, and only Pang De died unyieldingly. When Cao Cao heard about it, he lamented for a long time and said: "I know that Yu Ban has been in danger for thirty years, how can I think that I will be in danger and not as good as Pang De?" (Yu Ban was recommended to Cao Cao by Wang Lang in 192, and it had been nearly 30 years by 219)

At the beginning, Pang De followed Cao Ren to attack Wancheng, and then followed him south to prepare for the crusade against Guan Yu, when the generals of Fancheng were suspicious of Pang De's brother Pang Rou because he was in the Shu army in Hanzhong. Pound often said: "I have received the favor of the country, and I will sacrifice my life for the country." I want to attack Guan Yu personally, if I don't kill Guan Yu in the future, Guan Yu should kill me. Later, Pound personally fought with Guan Yu and shot Guan Yu in the forehead, at that time Pound always rode a white horse, and Guan Yu's soldiers called him the White Horse General, and they were very afraid of him.

Cao Ren asked Pang De to settle in the place ten miles north of Fancheng, when the sky was raining for more than ten days, the Han River overflowed, and the water under Fancheng was five or six zhang deep, so Pang De and the generals avoided the water embankment. At this time, Guan Yu attacked Pang Dejun by boat, and shot arrows from all sides of the big ship to the embankment. Pound was armoured with a bow, and the arrows were not in vain. General Dong Heng, general Dong Chao and others wanted to surrender Guan Yu, but they were all beheaded by Pang De. Pang De fought hard from Pingdan to the middle of the day, Guan Yu's offensive became more and more urgent, the arrows were exhausted, and the two sides engaged in a short battle. Pound said to the governor Cheng He: "I heard that good generals are not afraid of death, they do not steal their lives, and martyrs do not destroy the festival to survive." Today is the day I die. So he fought angrily and fiercely, and his spirit became stronger, but the flooding was too strong, and the Wei soldiers surrendered. Pang De and his subordinates, one of them, and Wu Bo, collected bows and arrows, and took a small boat to return to Cao Ren's base camp. However, the storm was too strong, the boat was sunk, the bow and arrow were lost, and Pang De held the boat alone and covered the water, which was captured by Guan Yu, and was driven back to Guan Yu's camp without kneeling.

Guan Yu said: "Your brother is now in Hanzhong, and I am planning to use you as a general, why don't you surrender early?" Pang De scolded Guan Yu and said: "Shaft, what is surrender!" The king of Wei led a million soldiers to invigorate the world. Your Liu Bei is just a mediocre talent, how can he be against the King of Wei! I'd rather be a ghost of the country than a thief. Guan Yu saw that he did not surrender, so he killed Pang De.

When Cao Cao heard this, he was very sad, wept over his death, and made his two sons liehous. After Cao Pi took the throne, he sent an envoy to the tomb of Pang De to send a nickname. The edict said: "In the past, the ancestors sacrificed their lives for the country, and the king died on hunger strike, and died of martyrdom, and the previous generations praised them. Pound was resolute and resolute, and he went to the difficult to make a name, and people praised him at that time, and his righteousness was very noble at that time, and the widow remembered him and gave him the nickname of Zhuanghou. He also gave his son Pang Hui and four others the title of Marquis of Guannei, each with a hundred households. Pang De's son Pang Hui later destroyed Shu with Zhong Hui, Deng Ai and others, and Pang Hui almost killed Guan Yu's descendants after Liu Chan surrendered.

After the surrender of Yu Ban, after Pang De died in battle, Cao Ren only led thousands of soldiers to defend Fancheng, and the water flooded almost the entire city. Guan Yu attacked the city by boat, surrounded several layers, the city and the outside were cut off, there was little food left, the city wall also collapsed in many places due to flooding, the army panicked, but the reinforcements had not yet arrived.

Someone said to Cao Ren: "Today's crisis is not so easy to support, while Guan Yu has not yet joined forces to besiege the city, he should take a light boat at night, abandon the city and flee, so that he can escape." At that time, Runan was too full of favor and persuaded Cao Ren to say: "The torrent comes and goes quickly, I hope it won't be too long." I heard that Guan Yu sent other generals to Jiaxia, from the south of Xuchang, the people are very worried, Guan Yu does not dare to attack now, because he is afraid that our army will become horns behind him. If we run away now, the place south of the Hong River will not be owned by our country, so please hold on and wait. Cao Ren said, "That's right. Cao Ren also inspired the courage of the soldiers and expressed their determination to defend the city to the death, and the soldiers were moved by their spirit and were dedicated to defending the city, so everyone reinvigorated.

Earlier, Sima Yi had advised Cao Cao that Hu Xiu, the assassin of Jingzhou, was rude, and Nanxiang was too arrogant and arrogant, so he should not be stationed at the border, but Cao Cao did not pay attention to it, and as a result, when Wancheng rebelled and Guan Yu crusaded against Xiangfan, the two also turned their backs on the country and took refuge in Guan Yu.

Later, Guan Yu sent other generals to surround the general Lu Chang in Xiangyang, and the people of Lu Hun, Sun Wolf, rebelled, killed the county lord, and returned to Guan Yu in the south. Guan Yu gave Sun Wolf the official seal, gave him the army, and asked him to go back to be a thief. In the south of Xudu, there were people everywhere echoing Guan Yu, and Guan Yu's prestige shook the entire Central Plains.

【Cao Ren who fell to the downwind】

Now many people think that Yu Ban, Pang De and others are Cao Ren was besieged, Cao Cao sent to support, this may be a little misunderstood, "Pang De Biography" recorded as "Hou Yin, Wei Kai and other Wan rebelled, the German general and Cao Ren attacked Wan, cut Yin, Kai, Sui Nantunfan, ask Guan Yu". It can be seen that Pang De was a general who followed Cao Ren from the beginning, and was not sent by Cao Cao to support Cao Ren in the later period. In "The Biography of Yu Ban", there is a record of "sending Ban Zhuren again", and it can be seen that only Yu Ban is actually the general sent by Cao Cao to support Cao Ren.

And Cao Ren had a lot of troops in Fancheng at that time, after all, Cao Ren was originally here to crusade against Guan Yu, but Cao Ren did not have many troops left in Fancheng, "The Biography of Cao Ren" shows that after Guan Yu flooded the Seventh Army, there were still thousands of troops stationed in Fancheng, so the troops in Fancheng might even be about 10,000 before.

The record of Guan Yu's prisoners after the war, "Zizhi Tongjian" is "Yu De Yu Ban and other people and horses are tens of thousands", and "Wu Zhubiography" is "Yu Yi Zhou soldiers are forbidden to wait for 30,000 horses to send Jiangling", that is to say, Guan Yu captured at least 30,000 prisoners, so Yu Ban, Pang De and others outside the city The total strength of the conservative army is also more than 50,000, plus the troops of Fancheng and Xiangyang, Cao Ren's total strength at that time was more than 60,000, and 60,000 is just a conservative number, and the previous article also said that Guan Yu's army at that time should be about 30,000, so it is calculatedAt that time, the ratio of forces between the attacking side and the defending side was quite large, below 1:2.

According to the record of "Ben Envoy Detun Fan Bei Ten Li" in the "Biography of Pang De", it can be seen that Cao Ren's strategy against Guan Yu is to garrison with a small number of troops in the city, and the army is outside the city, waiting for the opportunity to move, after Yu Ban comes, it is estimated that the army outside Fancheng is mainly controlled by Yu Ban, as for how many troops Yu Ban brought to the rescue, I personally think it may not be much, because Cao Ren himself is ready to crusade against Guan Yu, and the troops in his hands are enough to defend and even attack.

Cao Ren put most of the troops outside the city, waiting for the opportunity to move, a small number of troops to defend Fancheng, this strategy seems to be no problem, after all, Cao Ren has many soldiers, Guan Yu has few soldiers, and it is enough to guard thousands or more than 10,000 troops in Fancheng, Cao Ren's goal is not simply to repel Guan Yu, in this kind of military advantage, Cao Ren of course wants to defeat Guan Yu directly.

But Guan Yu dared to attack Fancheng in this situation, of course, there are also hole cards, Cao Ren's strategy is likely to have been expected by Guan Yu before the war, and even this situation is guided by Guan Yu, otherwise why after the big flood, Cao's army was flooded, and Guan Yu's army would be fine, otherwise why did Guan Yu dare to take the initiative with a small number of troops, and dare to cross Xiangyang to fight Fancheng directly.

Cao Ren is not weak, but Guan Yu is stronger.
