While Zhang Liao was preparing for the night attack, the sky gradually darkened unconsciously.

The scouts sent by Zhang Liao to monitor Liu Bei and Zang Ba's army outside sent information back from time to time, so that Zhang Liao could know the general state of Liu Bei and Zang Ba's army camp.

At the third watch in the middle of the night, Zhang Liao made all the preparations and walked out of the military village with 3,000 elites from Bingzhou.

For a while, it was a horsebit ring, and everyone would not make any noise easily, and the horse's hooves were also wrapped in a thick cloth to reduce the sound of the horse's hooves.

Everyone didn't put on torches, but under the guidance of some people who could see at night, they slowly moved towards Liu Bei and Zang Ba in the direction of the military village by taking advantage of the nightlight sky.

Zhang Liao and Hou Cheng also walked in the front, and behind them were the three hundred iron cavalry of the state, but now in order to save the physical strength of the war horse, all the cavalry are also leading the horse.

After walking for about half an hour, he gradually approached the vicinity of the camp set up by Liu Bei and Zang Ba.

This is also the location of a barren field near the Surabaya River, surrounded by abandoned fields that have long since grown barren grass, and some improvised felled trees have been used to build a simple camp wall.

If you look at it during the day, you can still see that most of the wooden bars that make up the camp wall are a little damp with sap, and at night, there is only a smell of grass and trees coming from the wind.

According to the previous scout report, although Liu Bei and Zang Ba's armies were stationed in a camp, they were also divided into two blocks, left and right.

Between the two armies is where the main tent of the army is, but Liu Bei and Zang Ba did not live in the main tent, and they also returned to the camp tent where their respective armies were stationed at night.

However, to be honest, there are very few large areas of woodland around Pengcheng that can be cut down for timber.

When Cao Cao attacked Xuzhou twice, he also launched a siege and siege of Pengcheng, so Cao's army also cut down a lot of trees around Pengcheng for use, and there are naturally not so many trees that can be harvested for people to recover that take more than ten or hundreds of years to recover.

Now the coalition forces brought by Liu Bei and Zang Ba can only barely find some trees to use.

After all, the combined forces of Liu Bei and Zang Ba are nearly 30,000 people, even if there may not be many regular soldiers among them, maybe more than 10,000 people are actually young and strong people, but after all, there are so many people who need to be accommodated in the camp, so the wood needed to build the camp is naturally not less.

For this purpose, it is often necessary to cut down all the trees in a forest area to meet the needs of the camp.

Nowadays, the timber for Liu Bei and Zang Ba to build the camp is obviously insufficient, so the camp wall built is not very thick, and there are not many deer firewood and horse barriers outside the camp wall, so that the soldiers and horses of the night attack can easily get close to the camp.

Of course, although the defense of this camp is insufficient, Liu Bei and Zang Ba still prepared many people on the sentry tower in the camp to guard against foreign enemies who may attack around them.

But this kind of vigilance still works during the day, and now that it is night, the line of sight is naturally limited.

The night guards on the watchtower couldn't see too far at all, and after a certain distance, it was completely pitch black all around, and by the time they could see people, they were basically less than two or three hundred steps away from the camp.

This is also the confidence of Zhang Liao to dare to attack at night.

When Zhang Liao led his troops to Liu Bei and Zang Ba's camp one mile away, he stopped first, and then sent one or two hundred elite soldiers led by Hou Cheng to touch the direction of the camp first.

As for Zhang Liao, he and the three hundred iron horsemen were ready to mount their horses at any time, just waiting for Hou Cheng to open a camp wall in the camp in front, and then rush to the camp with more than 2,500 other soldiers.

Let's talk about Hou Cheng's side for the time being, Hou Cheng led people to walk quickly in the direction of Liu Bei and Zang Ba's camp, and soon saw the camp wall lit with bonfires around the camp, and also saw the soldiers standing in the four- or five-step sentry tower in the camp.

The soldiers in this guard tower are generally five people, and under the supervision of the captain, the other four soldiers each look in one direction to watch, but they are not lazy or dozed off.

Seeing this scene, Hou Cheng carefully led people to approach the range of about 300 steps outside the camp first, and then fell directly to the ground and quickly crawled to the side of the camp wall.

This can also reduce the possibility of being discovered, obviously Hou Cheng is very good at this kind of sneak attack, and the soldiers brought by Hou Cheng are also fast, and they don't make much movement, and they are all attached to the wall of a camp.

Hou Cheng looked through the gap in the wooden fence of the camp wall, there were many tents inside, and a lot of bonfires were burned for lighting, and occasionally some patrolling soldiers walked by, and it seemed that the troops inside had fallen asleep.

Hou Cheng was also a lot relieved, this didn't seem like an ambush, and then he tried to push the camp wall, feeling that the camp wall was a little shaky, obviously there was no too stable foundation.

This made Hou Cheng have a little more confidence, so Hou Cheng used the light of the bonfire to call the soldiers around him to work hard together, and at the same time pushed and hit the camp wall.

"Boom la la ......"

As Hou Cheng led people to hit the camp wall together, the camp wall was knocked over by everyone in a short time, and for a while, the surrounding camp walls were affected, and they fell directly into the camp.

A gap of at least a hundred paces had been opened in one direction of the camp, enough for the army to rush in from here.

"Enemy attack... Enemy attack ......"

This movement was discovered by the soldiers on the sentry tower as soon as possible, so a burst of shouts sounded, and then the piercing gong sound of "Bang Bang" also sounded, which alarmed the troops of Liu Bei and Zang Ba in the camp.

"Kill!"

Zhang Liao heard the movement in front of him, turned over his horse directly, pointed at the camp in front of him with a lance knife in his hand, and killed him with three hundred iron cavalry and more than two thousand five hundred soldiers.

"Rush, rush!"

It was only a straight line distance of one mile from Zhang Liao's location to Liu Bei's and Zang Ba's camp, so Zhang Liao and his three hundred cavalry had already rushed to the front of the camp breach not long after.

At this time, Zhang Liao didn't wait for the foot soldiers behind at all, but just rushed to the front with the three hundred iron cavalry.

When Liu Bei and Zang Ba broke through the camp, Zhang Liao saw that Hou Cheng with one or two hundred people still stayed here to respond, and did not enter it.

Obviously, Hou Cheng still has a little less desperate heart, but he is just going to wait for Zhang Liao to bring his troops over, and then go inside.

Judging from the situation in the camp, Liu Bei and Zang Ba's army seemed to be very chaotic because of the night attack, and many of the soldiers in the tent just ran around there after getting up, not looking like they were on guard.

Of course, at this time, Zhang Liao and Hou Cheng didn't know whether the camp area they broke through was where Liu Beijun was located or Zang Bajun, but when they saw the situation inside, the two of them were a little less suspicious......
