In some TV dramas we watched, the siege was the most exciting part. The soldiers put the ladder on the wall, and wave after wave of soldiers began to climb crazily. Soldiers guarding the city will throw stones down from the top floor and even throw feces. The audience was very anxious. Can't they just push down the ladder? So in history, did the soldiers guarding the city push down the ladder? The answer is no, because it can't be pushed.

There are many reasons,

First, the ladder can be fixed at the joint.

At that time, the ladder was quite special, called the ladder. This kind of structure is very complicated, with a hook at the top, which can hook the ladder and the city wall well, and the ladder is also very heavy. This kind of ladder first appeared in Xia, Shang and Zhou dynasties, and later Luban reformed it, which could reduce a lot of manpower.

He added a base under the ladder. The base consists of six wheels, and the whole ladder can be folded. Everyone can understand that the ladder is installed in the car. The main feature is that it is heavy and tall. It is difficult for people in the city to move a ladder composed of hooks and bases. It takes a lot of time to chop with an axe or something, so they have to throw stones and shoot arrows from it.

Later, the transformation was more complicated and the volume became much larger. In the past, when soldiers climbed up, they couldn't stop the stones thrown from above. For defense, they developed into an open-air building with a protective shield in front. In addition, there are winches and other equipment, equipped with an auxiliary ladder. The auxiliary ladder can be adjusted at any time, with wheels for lifting, and can move freely without manpower. The main ladder does not need to lean against the city wall. Archers can climb this open-air building to shoot arrows at the soldiers who are attacking the city, and they can also see the situation of the enemy opposite.

When all the conditions are met, the soldiers can approach the tower again and win it in one fell swoop. This method was used for a long time, but it was abandoned after the Ming Dynasty because it was too bulky to resist firearms.

The second is that you can't do it.

When using the ladder, we will choose some auxiliary tools, such as fan car, dust car, wooden curtain and so on. When the soldiers climbed up, they sprinkled pepper noodles on the soldiers guarding the city with dust trucks, which narrowed the enemy's eyes and blurred their sight, so that they had to stop attacking immediately and their own troops could easily enter the city. Fan trucks are used to spray lime, poisonous gas or smoke to clear obstacles. Next, the soldiers who attacked the city put the baffle in the wooden curtain in front of them through the support, which can stop the attacks of arrows, stones and so on and help cover the soldiers to board the tower.

Another reason is that the ladder is too long.

Because the tower is very high, the ladder must be adjusted with the height of the tower. Once the ladder is long, it will be too heavy to push down. Moreover, ladders are not conducive to handling. Later, many portable ladders appeared, and there were many forms, such as bamboo flying ladders and flying ladders. The main feature is that they are light and long.

In the Song Dynasty, the flying ladder was twenty or thirty feet long and had two wheels at one end, which was convenient for soldiers to board the city. The requirements for siege soldiers are also very high. They must be stronger than their opponents. "Wu Beizhi in? All kinds of ladder forms are described in the ladder diagram. Different forms are suitable for different kinds of siege. Besides climbing ladders, there are archers attacking the city. As soon as they appear, they will turn into hedgehogs, let alone push them with their hands. As soon as they reached out, they were already stabbed.
