There are roughly four methods for siege during the Three Kingdoms period.

Water attack, psychological tactics, siege, and strong attack.

Needless to say, the siege of the city is nothing more than surrounding the city, breaking the city by cutting off water and food, or digging tunnels, etc.

Among them, water attack requires special terrain to be implemented. The famous method of water attack is that when Qin State attacked Chu, Bai Qi attacked Yancheng, an important town of Chu State. At that time, although the terrain of Yancheng was low-lying, there were no suitable rivers around for water attack. After detailed geographical survey, Bai Qi used hundreds of thousands of troops and civilians to dig channels, build embankments, and divert water to irrigate the city for dozens of kilometers. After the war, this channel was used to solve the irrigation problem. It was called the Baiqi Canal and was still used in later generations.

During the Three Kingdoms period, Guan Yu also used the method of water attack, facing Yu Jin, the general of Cao's army, flooded the seven armies, forcing Yu Jin to surrender, kill Pang De, and shocked China.

Psychological tactics, which is to take advantage of the psychological weaknesses of the defending forces, and to persuade the generals to surrender, incite the people in the city to rebel, or the soldiers mutiny, or the defending party's unsteady fighting spirit, adopt the strategy of three missing one to lure the opponent into breaking through, and then annihilate the opponent in the field.

The focus is on direct siege, which is generally divided into two parts: cover of long-range weapons and infantry climbing the city. In a few cases, tunnels are also dug, but the success rate is not high. Long-range weapons, bows and arrows, infantry crossbows, large bed crossbows, and lever catapults. In order to increase the range and power of these weapons, soldiers will be sent to transport soil to build soil mountains if time permits, and these long-range weapons are placed on the soil mountains. Of course, there are better hills nearby with suitable distances.

Infantry climbing the city, there was an image in ancient times called "ant-attachment", which means climbing up like ant, mainly for the sea of ​​people tactics, but there are also many techniques, such as advanced cloud ladders and fly bridges, which can greatly increase the climbing speed and reduce the climbing speed. The coordination of long-range weapons can effectively suppress the long-range weapons at the top of the city. Reasonably equipped slings and rattan cards can reduce casualties caused by enemy arrow stones.

Good time and rhythm control of attacks can maintain morale in siege, and strict rewards and punishments can inspire morale, etc.

However, the death rate of direct attack is also the largest. If it is not far better than the enemy's troops and attack with all their strength, the chance of victory is not great.

Moreover, even if the troops are far superior to the opponent, some preparations are needed before siegeing the city, such as the first batch of soldiers who siege will be given wine and meat to boost morale. If the city has a moat, soldiers will need to carry earthblocks to fill the moat.

The first soldier who climbed the city will receive a heavy reward. If he dies, the reward will be given to his wife and children. Usually, the chance of climbing first is high. If he climbs onto the city and is overwhelmed by the enemy's reserve team, the person who fights on the city to the end of the city will also have a heavy reward.

These two items are two necessary rewards for siege battles. Sometimes prisoners and soldiers who violate military discipline in the army will be organized into suicide squads for the first batch of sieges. The moment these people step onto the city, no matter how big the crime is, they will be pardoned.

However, it is obvious that there is no such person in Guan Yu's army. Guan Yu uses strict military discipline to command and mobilize his soldiers.

After his charge order, the archer camps on both sides used dense bows and arrows to suppress the defenders on the Huainan City Tower to counterattack.

The 30,000 troops below pushed the chariot and the ladder began to attack.

However, it is obvious that the defenders in Huainan City are also firm in their will and have a strong desire to defend the city. After Guan Yu led his troops and rushed three times in a row, he failed to defeat Huainan City.

The first group of soldiers who climbed the city were beaten down by Wenpeng's men.

When the 30,000 troops were killed or injured, Guan Yu had to give up and retreat from the front.

"Brother, the last one is useless and I can't conquer this city!"

After some battle, Guan Yu was defeated.

Back in the military tent.

In this tent, the three commanders gathered here. There were not many people under Gongsun Zan's army in this attack, because most of the subordinates were mainly cavalry, and even if they attacked the city, they would only make a few shouts.

Among the ten thousand people who were killed or injured were mainly those under Liu Bei and Liu Chong.

"Everyone, it's my responsibility to fail to attack Huainan City, I'm sorry."

Liu Bei spoke and said something to everyone first.

"Xuande, you are not blamed for this matter. We don't know that there is Liu Zheng's army in Huainan City. If it were just the information we discovered before, and there were only more than 10,000 troops in the city, it would definitely be able to be defeated. Now that Liu Zheng is here, we know that Liu Zheng must have arranged heavy troops here!"

Gongsun Zan did not blame Liu Bei.

"Although we did not capture Huainan City, seeing Liu Zheng here is also good news. As long as we can restrain Liu Zheng here, Lu's army can attack Xuzhou with all its might, leaving Liu Zheng clones unable to do anything!"

Gongsun Zan did not think that this battle was useless. At least they knew that Liu Zheng had already deployed troops in Huainan County in advance. Liu Zheng did not have many troops in Yangzhou. Now that all of them have been brought here, it means that Liu Zheng's troops in other places have decreased.

As long as Liu Bei and Gongsun Zan restrain Liu Zheng in Huainan County, the greater the chance of Lu Zhi's surprise attack on Xuzhou.

"Yes, so our attack just now was just a tentative attack, and we didn't really want to fight against Liu here to the death."

"As long as we prove that Liu Zheng has a large number of troops here, we can change our strategy. There is no need to rush to attack the city, and continue to waste time with Liu Zheng here."

Liu Bei was not afraid of the war of attrition, so he confirmed that Liu Zheng was in Huainan City, but he was the one he was not worried about.

As long as time is spent, Yuan Shao’s situation in Qingzhou will definitely be very good. After Qingzhou falls, Lu Zhi’s situation in Xuzhou will definitely be at an advantage.

By then, if two states are occupied in succession, Liu Zheng will lose two wings. Although he will not be in a slump, he will suffer a lot of power and the threat will not be that great.

"Actually, everyone, I have a way, maybe I can defeat Liu Zheng."

When everyone was discussing the siege of Liu Zheng, Liu Chong, who had not spoken, said something.

He spoke, which made him, who had no sense of existence, suddenly become the focus of everyone, and everyone looked at him.

"King Chen, do you have any opinions?"
