In history, after the death of Lü Meng, the commander of the west recommended by him was not Lu Xun, but Zhu Ran, and then Cao Pi sent troops to the south in three ways, and Zhu Ran became the commander of the Western Front to resist Cao's army. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Because Cao Pi personally sat in Wancheng, the army on the Western Front gathered, which was likely to be the main direction of attack of Cao's army, but although Cao's army successfully surrounded Jiangling all the way in the early stage, it was unable to conquer for a long time under Zhu Ran's persistence, and finally encountered an epidemic and had to retreat.

【Western Front Battlefield】

On the battlefield of the Western Front, Cao Pi sent the general Cao Zhen of the Shang Army, the general Xiahou Shang of the southern expedition, the left general Zhang He, and the right general Xu Huang to surround the southern county, while the Wei emperor Cao Pi cheered in Wancheng, while Sun Quan defended Jiangling with Zhu Ran, and sent the left general Zhuge Jin, the Pingbei general Pan Zhang, and the general Yang Cang to save the southern county.

When Lü Meng was seriously ill, Sun Quan asked Lü Meng: "If you can't rise up and serve me again, who can replace you?" Lu Meng replied: "Zhu Ran is more than enough to be bold and guarded, and I think he can accept the appointment in my place." After Lü Meng's death, Sun Quan pretended to be Zhu Ran with a charm and guarded Jiangling.

Cao Zhen and Xiahou Shang broke through Niuzhutun, and Sun Quan sent Sun Sheng to lead 10,000 men to defend the state and establish a dock as Zhu Ran's external rescue force. Zhang He led his troops to attack Sun Sheng (one said that Cao Zhen defeated Sun Sheng, but I personally haven't found the source), Sun Sheng couldn't resist and immediately retreated, and Zhang He garrisoned the state, cutting off Zhu Ran from foreign aid.

Sun Quan sent Pan Zhang, Yang Cang and other generals to relieve the siege, but they still failed. After Wu Zuo's general Zhuge Jin arrived, he confronted Xiahou Shang across the river, and Zhuge Jin led his troops across the river to Xiaozhou in the river, and scattered the naval army on the nearby river. Xiahou Shang used many small boats, carrying more than 10,000 feet and cavalry at night, quietly crossed the river from the downstream, attacked Zhuge Jin's various armies, burned their ships, and attacked by land and water, defeating Zhuge Jin's army.

According to the record of "Wu Lu", Cao Zhen, Xiahou Shang and others surrounded Zhu Ran in Jiangling, and divided Zhongzhou, and Jin rescued it with soldiers. Jin is slow, reasoning, planning, no response to the art of ambush, the soldier has been puzzled for a long time, and the right to look at it. and Chun Shuisheng, Pan Zhang and others made the water city in the upper stream, Jin attacked the pontoon bridge, and really waited for the retreat. Although there is no great honor, it also contributes to the protection of the whole division.

At that time, many of the defenders in the city were suffering from swelling, and only 5,000 people were still capable of fighting. Cao Zhen and others built earth mountains, dug tunnels, built buildings and turrets to approach the city wall, arrows rained down, the soldiers were frightened, Zhu Ran Yan was fearless, inspired the soldiers, and took advantage of the enemy's tactical loopholes to break through the enemy's two military camps. The Wei army besieged Jiangling for six months and had not yet retreated. Jiangling ordered Yao Tai to lead the army to garrison the north gate, and saw that the Wei army was strong, the defenders in the city were few, and the grain and grass were about to run out, so he colluded with the Wei army and tried to act as an internal response. When he was about to implement it, the matter was discovered, so Zhu Ran beheaded Yao Tai according to military law.

After Cao Zhenjiu couldn't conquer it, he saw that the Yangtze River was shallow and narrow, and Xiahou Shang wanted to take a boat to lead the infantry and cavalry into the middle of the river to camp on land and make a pontoon bridge, and the north and south of the bridge could be exchanged.

After Dong Zhao learned about it, he said: "Emperor Wu's wisdom and bravery are beyond ordinary people, and he attaches great importance to the enemy when he uses his troops, and he does not dare to underestimate the enemy like this." Now that the army is stationed in Zhouzhu, it is already very deep; It is very dangerous to cross the water on a pontoon bridge; It is very narrow to travel from only one road. These three situations are taboo for soldiers, and now they are all practiced. If the thieves frequently attack the pontoon bridge, and there is a little omission in our defense, then the elite forces in Zhouzhu will no longer be owned by Wei, but will be transformed into Wu. Isn't it too confused for the ministers to be privately worried about this situation and forget to sleep and eat, while those who are planning about this matter are content and do not think they are worried? In addition, the river water has always been going to rise, once the river water soars, what to use to defend it? If you can't break the thief soldiers, you'll be finished first. Why are you not afraid of the dangerous terrain? Things are going to be very dangerous, and I hope Your Majesty will look into these situations! Cao Pi understood Dong Zhao's words and immediately ordered Xiahou Shang and the others to withdraw quickly.

At that time, Zhu Ran, who was besieging Nanjun by Xiahou Shang and others, divided the front army of 30,000 people to build a pontoon bridge, crossed the Baili Island, Zhuge Jin and Yang Cang combined troops to rescue, but they did not know the enemy situation and failed to rescue, and the Wei army had soldiers crossing the river every day. Pan Zhang believed: "The Wei army was strong at the beginning, and the river was shallow, so it was not time to fight them in a decisive battle. He led the army to fifty miles upstream of the Wei army and established the water city. He also cut down millions of bundles of reeds and tied them into rafts, trying to set fire to the pontoon bridge along the river. And Zhuge Jin attacked Xiahou Shang on a large scale, and Xiahou Shang and others finally chose to withdraw because they had been attacking Jiangling for a long time and suffered from epidemics.

The Wu army advanced in two ways, while the Wei army retreated all the way, breaking down from time to time, and the generals Shi Jian and Gao Qian were only spared. The Wei army withdrew for more than ten days, and the river swelled. Cao Pi then praised Dong Zhao for having the same insight as Zhang Liang and Chen Ping. Zhu Ran shocked Cao Wei because of his prestige and was renamed the Marquis of Dangyang.

Although Cao Wei nominally had four generals, Cao Zhen, Xiahou Shang, Zhang He, and Xu Huang in the Western Front battlefield, Xu Huang may actually be sitting in Xiangyang and responsible for support in the rear, and did not directly participate in the battle.

The battlefield on the Western Front mainly revolved around the city of Jiangling, with Cao Wei wanting to capture Jiangling and Sun Wu wanting to keep Jiangling. In the early stage, Cao Wei actually had the upper hand, Cao Zhen, Xiahou Shang, and Zhang He won victories one after another, broke Niu Zhutun, and also defeated Sun Sheng, completely cut off the external contact of Jiangling City, and successfully surrounded Jiangling, and then Sun Quan sent Zhuge Jin, Pan Zhang and others to support Zhu Ran, but they all ended in failure.

However, in this situation that made people feel that Jiangling was not going to fall in a day, the situation was reversed, and the direct reason was that Cao Zhen, Xiahou Shang and others could not defeat Zhu Ran and conquer Jiangling. Jiangling City is an important town in Jingzhou, although its defense is good, but there are not many soldiers under Zhu Ran who can fight, because many of the defenders are suffering from swollen diseases, and there are only 5,000 people left who are still capable of fighting, but Zhu Ran relied on these 5,000 people to defend Jiangling for six months, and even the internal rebellion failed to defeat it, and Xiahou Shang and others just couldn't do anything about him.

And Zhu Ran's persistence finally ushered in a turning point, Xiahou Shang began to take a risky strategy in order to break the city, large-scale construction of pontoon bridge attack, but was burned clean by Pan Zhang, Wei Wen Emperor Cao Pi listened to Dong Zhao's advice, and asked Xiahou Shang to withdraw in advance, so as to avoid greater losses of Cao's army.

At this time, there was another outbreak of plague in the Jiangling area, the water level rose sharply, and when the time and place were not suitable, Cao Pi finally ordered the whole army to retreat.
