At present, the form of Taishan County is from Fenggao to Boxian and then to Liangfu, forming a line of defense. On this line of defense, there are Turtle Mountain, Youlai Mountain, Liangfu Mountain, and Wenshui. Tai Shi Ci is leading his troops to attack Fenggaocheng, and Guan Yu has already sent troops from Lu State and is about to lurk in Chengxian County behind Liang Fu. At this time, Xiahoudun still knew nothing.

Guan Yu decisively launched an attack. It was one of his military adventures. In the case of the loss of Jiujiang County, he must make a show of prestige elsewhere. Although it was Liu Bei's decision to abandon Jiujiang, it was reflected in the army, and the retreat of the army without a fight made the army's heart shake a little. After learning that the Yangzhou army had no intention of resolutely going north in Jiujiang for the time being, Guan Yu knew that the opportunity had come.

left Wu Kuang and Liu Ye in Xuzhou. Thinking about it, even if the Yangzhou army goes north, it should be fine to entangle them temporarily. As long as Guan Yu can make progress with a surprise attack here, then he will be able to have enough time to go south to relieve the siege of Pengcheng after defeating Xiahoudun.

All the preparations made by Xiahoudun in Taishan County were to defend to the north, and the huge and in-depth defense line was to resist the pressure of Taishi Ci's soldiers. He thought that the soldiers and horses would come to help, but he never thought that there would be a group of soldiers and horses that suddenly appeared from the Lu State to attack his back. When the news of the loss of Chengxian County finally reached Xiahoudun's ears, the eyes of this confidant general who had followed Cao Cao for many years were full of disbelief. He grabbed the soldier who had come to report and asked, "Who is this coming?" ”

The little soldier knelt on one knee on the ground, trembling, if he could see Xiahoudun in the past, he would only be happy in his heart, but now he is here to report this bad news, he doesn't know what will happen to him, maybe he will be burned to ashes by the general's anger. The discipline formed in the long-term military camp made the little soldier speak calmly: "General Yu, looking at the city from a distance, it is the banner of Guanzi. It will be Guan Yu. ”

Xiahoudun was indeed very angry, and he was even more furious after learning that the soldiers and horses of Chengxian County had been wiped out, and none of the officials, including the county commander, had escaped. However, his good self-cultivation allowed him to restrain himself, and he did not embarrass the soldiers who came to report the news. He waved his hand and asked the little soldier to retreat, then he roared loudly in his room: "Guan Yu is far away in Xuzhou, why did he suddenly come to Mount Tai!" Hell, sentry! ”

There was a sparse noise in the room, and the soldiers and servants who passed by here did not dare to take a breath. For fear of attracting the attention of the general, and then the storm was also invited.

After smashing the furnishings of the room, Xiahoudun calmed down. He took out the map and looked at it carefully. In the end, he sighed, it was impossible for Taishan County to hold it anymore. In addition to the defense line he guarded, Mount Tai only had a few cities such as Nanwuyang in the lower part, and in the middle, there were hills and mountains. If he is not ready to withdraw his troops, he will be attacked by Guan Yu and Tai Shici. When the time comes, even if you want to retreat, there is no way out. You can't go to the south, and it's a no-man's land to the east, and then you can go to Xuzhou's Yaoyu. To the north are Tai Shi Ci and Qingzhou, and there is only one way to go, which is to abandon the two mountain camps, and then cross Wenshui to the west and retreat to Dongping Kingdom. However, if he retreats like this, it is equivalent to giving up all the two places of Mount Tai and Jibei. Without the buffer of these two places, can Yanzhou still be able to block Zhang Fei and Tai Shici?

However, Xiahoudun did not give up rashly, he ordered Sima Lüqian, who was in Fenggao City to resist Tai Shici, to leave the deputy general to guard Fenggao, and then led troops south to Liangfu overnight to join him, and sent countless sentries out to find out how many soldiers and horses Guan Yu had to go north. Will a small group of soldiers and horses come to harass them, or will a large number of them come to attack?

Xiahoudun decided to rely on Liang Fucheng and the two mountain camps to fight with Guan Yu.

Xiahoudun's idea was very good, but unfortunately, under the condition that Guan Yu had already informed Tai Shici, he could no longer hide the eyes and ears of the Han army from many means. As soon as Lu Qian came out of the city, Tai Shici, who was staring at the Fenggao garrison outside the city, noticed it. Even in the middle of the night, Tai Shi Ci knew that an army had hurried out of the city and headed south.

After getting the news, Tai Shici summoned Wei Yan and said, "Wen Chang, the soldiers and horses in the city have changed, and only then have scouts come to report, saying that Cao's army is going north of the city. I'm afraid that Xiahoudun knows that the general of Nanfang Guan is the best. Since Fenggao's troops have withdrawn south, we will raise a large army to attack the city early tomorrow morning. In this way, Feng Gao can also be pulled. ”

When Wei Yan heard this, his eyes rolled and he said with a smile: "General, why bother tomorrow, according to the opinion of the last general, it is better to take this opportunity to attack the city overnight." At this time, the enemy army has left, and it is the time when the city defense is negligent. If you go up with a drum, the enemy can be destroyed. ”

Wei Yan likes to take risks, and Tai Shici is also a bold man. When he heard Wei Yan say this, he couldn't help but have his blood churning and he was eager to try. So he said to Wei Yan: "Since this is the case, I will follow what Wen Chang said." ”

Wei Yan was overjoyed when he heard this, and said, "The last general is willing to be the first." Tai Shi Ci happily agreed.

When Lu Qian left, he instructed the deputy general to go as usual, and after the dawn, he would plant more flags at the head of the city, and then pull the strong men in the city to go to the head of the city to wear armor and pretend to be a defender. It can be concealed day by day, and it can be dragged out day by day, and try to buy time for General Xiahoudun. Then, when there was nothing to defend, he set fire to the city and withdrew from Fenggao City on his own.

After the lieutenant general accepted the order, he transferred all the remaining men and horses to the head of the city to patrol the city, and as for the levy of the young and strong, he planned to do it again during the day. Doing this at night will always cause some unnecessary disturbance. In this city full of tension and unease, people's heartstrings are already tense.

Late at night, everything is silent. Even the soldiers who changed the defense at the head of the city gradually couldn't resist the sleepy insects. The legs and blades in their hands began to grow heavier and heavier. And the neck seems to be difficult to support the head. The upper and lower eyelids are glued together very hard, and it takes a lot of force to separate them for a while. The lieutenant has gone to sleep. There's still a lot to do tomorrow. As for the officers and soldiers defending the city, because Tai Shici rarely carried out overnight attacks since the siege of the city, they couldn't help but gradually relax their vigilance. Also, there was no movement in the first half of the night, so who would come to make trouble when it was almost dawn. After staying up in the middle of the night, it is better to make plans at dawn.

When the balance in the hearts of the Cao soldiers gradually tilted, they didn't know that there were already groups of soldiers slowly sneaking in under the city. Through the darkness of the night and the shadows of the torch, they silently and quickly approached their targets. If someone throws a torch out of the city at this time, they will definitely see groups of Han troops.

Unfortunately, no one did. So, it also led to their doomed end.
