Many modern people will think of such a scene. Can't they go around? Do we have to attack the city? After all, modern cities basically extend in all directions. Basically, you can go anywhere you want from any direction. However, we should know that 19 12 China before the demise of the Qing Dynasty was very different from modern times.
In ancient times, the geographical position of building city walls was very high and the terrain was dangerous. In order to condescend to defend the enemy. In order to cope with the war, the ancient farming people used some special materials, such as civil engineering and masonry, to build a thick wall to resist the enemy's invasion.
During the Ming Dynasty (1368), after Zhu Yuanzhang led an army to conquer Huizhou, he visited a hermit named Zhu Sheng, hoping to find a way to run the country and keep the country safe. Zhu Sheng gave Zhu Yuanzhang nine words: "Build a high wall, accumulate grain widely, and be king slowly". Zhu Yuanzhang adopted Zhu Sheng's suggestion. Ordered a county to build a wall.
Later, when the eunuchs were in power in the Ming Dynasty, your indifference to state affairs gradually declined, the peasant army rebelled, and the Qing army took the opportunity to enter the customs. These walls also played a great defensive role. People who have seen the relevant history may be surprised. Why don't these rebels take a detour and have to attack head-on?
Historians believe that it is impossible to bypass it, or even dare to bypass it. Usually, the wall you see in TV plays may just be a wall. In fact, the ancient city walls are designed in strict accordance with the geographical environment, and are often built on the main roads, and are connected with the mountains and passes with dangerous terrain. Then make relevant strategic arrangements.
When the two armies are at war, if the siege side changes. Trying to bypass the city. So according to the design of the city wall topography. This must be a long detour. People in the city are waiting for food to be brought on the road. When the enemy arrived, they had already laid an ambush, occupied the dominant terrain and prepared for the ambush.
Therefore, walking around the city is simply abandoning the right place and people. Both of them are the most crucial things in the war. Compared with high-altitude siege. It may be opportunistic to bypass it and pay higher casualties. Therefore, experts will say: I want to go around, but I dare not. If it is so easy to bypass the past, then emperors of all dynasties have tried their best to even empty the state treasury to build a city. Isn't it meaningless?
