In the twentieth year of Jian'an (215), after Sun Quan and Liu Bei re-divided Jingzhou, he personally led the army north to attack Hefei again, but was defeated again, and was caught up by Zhang Liao in Xiaoyaojin and almost died.

【Conquer Anhui City】

In order to guard against Sun Quan, Cao Cao moved people in the Jianghuai area, making the south of Hefei almost uninhabited, and Cao Cao only left the important town of Anhui City in the south of Hefei to guard against Sun Quan.

In the nineteenth year of Jian'an (214), Cao Cao, in order to enrich the military rations, sent Zhu Guang, the Taishou of Lujiang, to cultivate land and plant rice in the Wancheng area. He also sent spies to recruit the bandit leaders in the Poyang area as an internal response. Lü Meng believed that "the fields in Anhui County are fertile, and if there is a bumper grain harvest, their soldiers will increase, so that after a few years, Cao Cao's advantages will be revealed, and Anhui County should be taken as soon as possible." So he explained the situation to Sun Quan in detail. Sun Quan thus personally conquered Anhui County, summoned the generals, and asked what the plan was. Lü Meng recommended Gan Ning as the governor of Shengcheng, and led the siege of the city on the front line, and Lü Meng himself led the elite soldiers to follow. Attacking in the early morning, Lü Meng personally beat the drums, and the soldiers enthusiastically climbed the city, and broke through the city of Anhui at breakfast. At that time, Gan Ning held a rope in his hand, took the lead in the soldiers, climbed the upper city, and finally captured Anhui City, captured Zhu Guanghe and joined the army Dong He. When Zhang Liao led his army to Jiashi, he heard that Anhui City had been broken by the Wu army, so he had to lead his troops back.

According to the "Book of Wu", at that time, the generals wanted to build earth mountains and buy siege equipment. Lü Meng said: "It takes many days to complete the construction of siege equipment and piles of earth. By that time, the enemy's city defenses have been consolidated, reinforcements will surely come, and we will not be able to capture the city of Anhui. Besides, our army came with a lot of rain and heavy water, and if we stay for a long time, the water will gradually recede, and we will encounter difficulties on the way back to our army, which I think will be very dangerous. Now it seems that this city will not be very strong, and the morale of our three armies is high, and they can be conquered quickly by attacking from all sides, and then returning to the army while the water has not retreated, which is the strategy of a complete victory. Sun Quan took this suggestion.

After the war, Lu Meng was the first, Gan Ning was the second, Sun Quan rewarded Lu Meng's merits, and immediately promoted Lu Meng to the Lujiang Taishou, and the captured soldiers, chariots and horses were all assigned to him, and 600 people were rewarded for Xunyang Tuntianke, 30 subordinate officials, and Gan Ning was worshiped as the general of Zhichong. After Lü Meng returned to Xunyang, less than a year later, the thieves in Luling were making trouble again, and the generals could not be captured, Sun Quan said: "There are hundreds of birds, not as good as one Peng." He also ordered Lü Meng to go to the conquest. Lü Meng's soldiers went to Luling, captured and killed the first evil, and released all the rest, allowing them to resume their old business.

After Lü Meng and others occupied Anhui, they laid a solid foundation for Sun Quan to attack Hefei again.

【Battle Hefei again】

In the eighteenth year of Jian'an (213), Cao Cao returned to the dynasty with Sun Quan's southern expedition and ordered Zhang Liao, Le Jin, Li Dian and others to lead more than 7,000 people to Hefei to station. Later, Cao Cao set out to fight against Zhang Lu, and handed over a warrant to the escort Xue Yi, asking him to take this signed urgent letter to Hefei to Zhang Liao, and note on the side of the letter that "the enemy will open it when he arrives".

Soon, Sun Quan led 100,000 soldiers and horses to surround Hefei again, so the generals opened the warrant together, and the above said: "If Sun Quan's soldiers come, the two generals Zhang Liao and Li Dian will go to war, Lejin will defend the city, and Xue Yi will not be allowed to participate in the battle." ”

The generals were puzzled. Zhang Liao said: "The lord is on an expedition outside, and when the helpers arrive, the enemy must have defeated us, so he ordered us to meet the enemy immediately while he was not yet concentrated, dampen their momentum, and calm the army, so that we can defend in the future." The chance of victory or defeat is in this battle, what do you doubt? ”

At that time, Lejin, Li Dian, and Zhang Liao were basically at the same level, and they were usually not in harmony with each other, Zhang Liao was worried that they would not agree, Li Dian said generously: "This is a major national matter, it depends on whether your strategy is good, (if it is feasible) how can I ignore the overall situation because of personal grudges!" After getting Li Dian's approval, Zhang Liao completely let go of his hands and feet.

So Zhang Liao recruited soldiers who dared to die overnight and got 800 people. Kill the calf and reward the soldiers, and decide to fight tomorrow. As soon as the morning dawned, Zhang Liao took the lead in attacking the enemy formation, killing dozens of enemy soldiers in a row, killing two enemy generals, shouting his name loudly, and rushing into the enemy camp until Sun Quan's banner. Sun Quan was so frightened that his subordinates were at a loss for what to do, so they fled to the top of the mountain and protected themselves with a halberd. Zhang Liao asked Sun Quan to come to the battle, but Sun Quan did not dare to move. Seeing that there were few soldiers led by Zhang Liao, Sun Quan's subordinates gradually gathered and surrounded Zhang Liao layer by layer. Zhang Liao broke through left and right, bravely moved forward, broke through the gap, and dozens of his subordinates rushed out. The remaining soldiers shouted, "Is the general going to abandon us?" Zhang Liao turned around and broke through the siege again and rescued the remaining soldiers, Sun Quan's men were invincible and did not dare to stop him. From early morning to noon, the morale of the Wu soldiers was completely lost, and they retreated to build fortifications. Everyone's mood settled down, and all the generals admired Zhang Liao very much.

At that time, Zhang Liao and other generals led the army into battle, and also wounded Xu Sheng, a general under Sun Quan, and then He Qi led his troops to resist the attack, only to get the spear that Xu Sheng lost when he was stabbed. Sun Quan besieged Hefei for more than ten days, and when he saw that it was impossible to break through, he led his troops to retreat.

【Defeat Hefei again】

In the twentieth year of Jian'an (215), Sun Quan led his troops north to attack Hefei for the second time, and personally led an army of 100,000 people, while the defenders of Hefei at that time were only more than 7,000 people, and the strength of the two sides was quite different, and at that time, because Cao Cao was far away in Hanzhong, it was foreseeable that Hefei's reinforcements could not come in time, but it was in this situation that Sun Quan lost again.

In the final analysis, I personally think there are several reasons:

(1) Sun Quan was not good at siege warfare. Siege warfare was very common in ancient times, and generally speaking, the defender had a great geographical advantage with the help of strong city walls, and could even achieve more enemies with fewer enemies. In addition to Sun Quan's two defeats in Hefei, he was earlier besieged by Kuang Qi when Sun Ce sent a crusade against Chen Deng, when Sun Quan's troops were more than ten times that of Chen Deng, but in the end Sun Quan returned in vain. It can be seen that Sun Quan is not very good at siege warfare, and in addition, Sun Quan made the mistake of underestimating the enemy, and the defeat is conceivable.

(2) Encountering epidemics. After Sun Quan besieged Hefei, his army suffered from an epidemic, so he finally decided to withdraw from the army. In ancient times, the plague had a great impact on the army, and Cao Cao suffered a plague in the Battle of Chibi and suffered a crushing defeat to Zhou Yu.

(3) Hefei City is strong and easy to keep. After Yan Xiang was killed by Sun Ce's faction, Cao Cao appointed Liu Fu as the new Yangzhou assassin history, when Liu Fu was in office, he moved the Yangzhou administrative office to Hefei, and actively prepared for war, saved a large number of materials, built a high city fortress for protection, Sun Quan's first crusade against Hefei failed and this has a lot to do with this.

(4) Cao Cao was prepared for a long time, and he was united in Hefei. When Cao Cao went out to fight against Zhang Lu, he was prepared for Sun Quan to go north, and he left a letter to Zhang Liao and others at that time, informing them of the countermeasures, and Zhang Liao, Li Dian and other generals could also maintain unity in wartime, and gave Sun Quan a blow to the head, which made Sun Quan have no chance to take advantage of it.

Overall, although Sun Quan had a huge military advantage in his crusade against Hefei again, he did not lose unjustly.
