The ancients said: “The general trend of the world must be divided for a long time, and a long time will be combined.”
In ancient China, there were countless wars. Wars were launched for the unification of the world, troops were sent for selfish interests, and for the defense of the country. Rise up to resist. The history of human development is like a history of war. We learn lessons from wars. Invisible competitive pressure forces countries to develop stronger, especially modern wars, which directly promote the rapid development of science and technology. The victory or defeat of a war may determine the survival of a country. The ancients have summed up experience from years of war, and compiled many military works from this. The most complete preserve today is The Art of War by Sun, and there are others. Military books such as "Wu Zi", " Sanlue " and so on.
War is not blind. The ancients had a lot of insights in the field of war. In order to occupy the enemy's city, they might try everything possible. Any war needs to be carried out with a plan. Although the situation on the battlefield is changing rapidly, there are also basics. Chapter law. Nowadays, in many films and TV dramas, we can still see fragments of ancient wars, from which we can find that it is a very difficult thing for the ancients to fight and siege the city, and they often pay a great price. Since there were no advanced siege tools in ancient times, one had to rely on things like ladders to climb up the city walls or risk their lives to knock open the city gates with wood. No matter which method is adopted, huge casualties cannot be avoided.
is similar to the battle of the Three Kingdoms Guan Yu Flooded Seven Armies . In fact, there is a very small chance that it will occur. Most siege battles in history are head-to-head. Then, some people may have questions: Why don’t the soldiers bypass the city and take the enemy’s back to break the city? Experts in history said: "You go around and try?" In fact, we can still see the ancient city walls and gates. The simulated images in the film and television dramas may be wrong, but the existing ancient cities can also restore the history. Even the ordinary walls are very high and strong. Not only that, but the ancients called it a "city" for a reason. The tall city wall and the moat were the most effective military defense structure in ancient times.
City walls and moats
The main function of ancient cities is military defense. In order to better protect the city, it is generally built on dangerous terrain or traffic arteries. The poet Li Bai once commented on the road of Shu that “one husband should be the gate, and no one can open”. The ancients believed that strategic essentials were very important for launching war or strategic defense. The State of Qin once relied on Hangu Pass to advance, attack, retreat and defend. The soldiers of the Six Kingdoms also had a headache seeing Hangu Pass, showing its strategic influence. Generally, the gates are built on dangerous terrain, and the surrounding areas must be barren mountains and ridges. If you want to lead a large army to attack the city, it is impossible to achieve it. For example, in the "Battle of Min", the five-nation coalition believed that the attack on Qin was always blocked at Hangu Pass, so they wanted to detour to Hangu Pass, but ultimately failed.
Secondly, ancient wars and marches often carried a large amount of military supplies. Ancient cities were generally not built in very open areas. If they are in danger, they may be attacked on all sides. Such cities are easy to be broken in wars, and there is no need for them. detour. If you encounter a city wall relying on topography and terrain, a large number of troops will detour, and it will take a lot of time for a while. Second, the number of marching troops is unlikely to be large. If the military supplies are cut off, the detouring army will become a turtle in the urn. The small group of troops took a detour, and there was no threat of breaking the city at all.
Finally, if a large number of troops forcibly detour to the rear, if they are caught by enemy troops, the consequences will be disastrous. If you want to bypass the enemy's city, it is not realistic to go straight to the rear. If one's own military strength is sufficient to crush the opponent, it can directly attack the opponent directly, and if the frontal attack fails to gain the advantage, it can also be through outspoken methods. If neither method is feasible, it can only be said to retreat earlier, and wars that lasted for several years in ancient times are not without, even if they attack the city, they will eventually return without success. If a city is simply attacked by a bypass, the significance of its construction is lost. The answers given by experts actually make sense.
With the advancement of technology, the traditional siege warfare has changed, and the existence of aircraft cannon makes the city walls vulnerable. Modern warfare is different from ancient warfare. Now it is very effective to send a small group of troops to sneak in. After all, the city now has no walls. If the frontal battlefield cannot be resisted, there is a direct danger of destroying the city. AncientDuring the war, the nomads might still have the opportunity to bypass the city during the period when the nomads were strong, and their mobility became the key winning factor, and the German army bypassed the Maginot Line in the modern war, but this is just an example. What is your opinion on this?
