The soldiers of Sima Jun couldn't help but feel ache. Logically, not every city has a moat. Only big cities like capital and state city can dig moats. Jiexiu is just a second-class small county town, and it also has a moat. It's so damn evil.

Jiexiu City originally had no moat, but when Cao Liang rebuilt Jiexiu City this time, he deliberately dug a trench outside the city and filled it with water. The purpose of this is naturally to strengthen Jiexiu City's defense.

If the Sima army wants to attack the city, it must first fill the moat. Arrows on the city keep shooting down and fill the moat in the rain of arrows. This is a task that is impossible to complete without paying a little casualty.

But this is also a task that must be completed. If the moat is not filled, the subsequent siege troops will not be able to launch an attack, so the first priority of the Sima army still needs to fill the moat.

Before launching the attack, Chen Qian and Sima Shi had already made preparations for this. Of course, the operation of filling the moat is also a routine operation when siegeing. Generally, small counties do not have moats, but larger counties and prefectures must have moats, so there are no technical problems in filling the moats. Most of the troops use sandbags filled with sand and soil to fill the river, and Sima Jun is of course no exception.

The Sima Army invested quite a lot of troops to attack. Ants attacked the city and played the tactics of the sea of ​​people. If each person carried a sandbag, he could prepare tens of thousands of sandbags at one time. If all of them could be filled into the moat, no matter how wide or deep the moat was, it would be no problem.

But the Bingzhou Army did not allow them to succeed easily. The Sima Army had to use shields to protect themselves during the attack and carry more than 100 kilograms of sandbags. Naturally, it was inevitable that they would lose sight of one thing and be hit by the Bingzhou Army's arrows.

During the attack with sandbags, the casualties of Sima's army continued to increase, but Chen Qian and Sima Shi did not care at all. Anyway, the Ant Support fought for the city and fought for people. This victory was entirely built with the lives of soldiers. How could it be possible to get Xia Jiexiu City without paying a little price?

Therefore, the Sima army's attack did not stop because of the increased casualties in the front. Instead, it continued to send more troops and vehicles to prepare to quickly fill the trenches.

The vehicles sent by Sima Jun this time were not ordinary vehicles. This kind of vehicle was called a siege vehicle. It is a siege vehicle specially used to avoid arrows and stones. It has a spire and covered with raw cowhide on the roof. The inside of the vehicle is wide and can be carried by more than ten armored soldiers. Four or five soldiers are needed to push it behind the vehicle.

The chariot is specially used to transport siege soldiers to the city, which can effectively avoid being attacked by the enemy's arrows and stones on the way to march. This is probably the predecessor of the armored personnel carrier.

However, today Sima Jun's chariot did not carry soldiers, but each chariot was loaded with dozens of sandbags. The soldiers behind pushed the chariot forward with all their might, rushed to the moat in one breath, lifted the rear of the chariot, and like a dump truck, they could dump dozens of sandbags into the moat.

This method was first proposed by Sima Shi, who used the high defense characteristics of the car to avoid attacks from arrows on the city, so that the attacking troops could minimize casualties.

Although the Bingzhou Army had a catapult, it was difficult to hit the catapult. Previously, it was a target of a fixed target. If you can't hit it accurately, you can adjust it before hitting it. The catapult is a mobile target, and aiming is the biggest difficulty, so it is almost impossible to use a catapult to deal with a catapult. If you throw out countless stone bullets, you can hit one or two at most.

After seeing it, Chen Qian said to Sima Shi: "It's still a good idea for the eldest son to use this transporter's carriage to transport soil. It's really easy to fill the trenches."

Sima Shi smiled slightly and said, "People can do their best and things can do their best. This carriage is a powerful weapon for siege, but it is the most suitable thing to use to fill the trenches at this moment."

With such "professional" trench filling equipment, Sima's army's efficiency in filling the moat has been greatly enhanced, and many casualties have been reduced. Next, the most intense siege battle was made. Chen Qian ordered the siege team to enter a state of preparation. Once the moat is filled, the subsequent troops will immediately take over and launch siege battles.

The Bingzhou Army on the city did not seem to have any good solutions for the car. The car moved quickly and could constantly change the route while moving. Such a goal was indeed a bit too much for the catapult, and it was quite difficult to hit it with a stone bullet.

In fact, the Bingzhou Army's catapult car has made many attempts to attack, but the effect is not ideal. Dozens of stone bullets were fired, and only one or two hit the target. In fact, it is hard to say that the catapult car is aimed accurately, but it just happened to hit it. So if the catapult car really needs to concentrate on the catapult car to deal with the catapult car, it is probably difficult to have any effect.

Now the Bingzhou Army has the only way to shoot with bows and arrows, but the upper layer of the car is equipped with thick wooden boards and covered with raw cowhide. It is almost impossible for the archers to shoot through it. Moreover, the current situation is that the car is filled with sandbags, and even if you shoot through it, it is useless.

If you really want to block the cart from moving forward, you can only shoot the soldiers who were pushing the cart behind the cart, but they were hiding behind the cart. The cart had a very wide eaves that covered the cart soldiers. The Bingzhou Army's bows and arrows would not turn, and they could not shoot the back of the cart no matter what.

First, Sima Jun's work on filling the trench was mainly people, but later, the casualties were relatively large, and the efficiency was far inferior to that of trench cars, so trench cars became the main force in filling the trench, and Sima Jun only sent archers to cover the convoy.

Several lieutenants watched Sima Jun's carriages shuttle back and forth freely on the battlefield. Seeing that the moat was filled by them little by little, they couldn't help but feel anxious and turned their eyes to Yang Hu, hoping that Yang Hu could come up with a way to stop these carriages.

Yang Hu didn't care. After all, the moat was just an auxiliary means of city defense. I have never heard of the city's defense, but it really counted on the moat. Even if it was broken through by Sima's army, it was relatively normal. There was nothing strange or anything to worry about.

The other party used chariots to fill the trenches, which was somewhat beyond Yang Hu's expectations. In the current situation, the Bingzhou Army did not have any good means to stop these chariots, so Yang Hu simply left it alone and devoted all his strength to the battle to defend the city.
