Although we have always called for peace in the world, a little careful observation will show that in the entire history of mankind, wars have almost dominated human history, and peace has been very rare.
At the dawn of human civilization, primitive tribes fought each other for various reasons. In the period of feudal society, the war was even more continuous, after all, at that time, the emphasis was on whoever had the biggest fist and who was the boss. Taking China as an example, the Spring and Autumn Warring States, the Three Kingdoms period at the end of the Eastern Han Dynasty, the Wei and Jin Dynasties and the Southern and Northern Dynasties, etc. are all famous chaotic years, and the chaos of the princes is normal, even the powerful Tang Dynasty is also in the process of conquest every year.
However, the reason why people fight wars is not simply to start wars, because war is only a means, and its real purpose is to rob the other side of its power and thus expand its territory, and war is nothing more than a measure to achieve the goal and be helpless to take.
Why is it helpless? Because for either side, the way to really like to seize the other side's power is to negotiate, or to use scheming to seize the other side's territory without bloodshed. These two approaches have the greatest strategic value, because they will not lose their own interests and can gain more power unconditionally.
This territory is actually a city. Ancient cities and pools were very important, especially in terms of strategic value. Because the city is there, it means that you still have strength, the city is gone, and you have no right to speak.
Therefore, the strength of one side's power can be judged by just looking at how many cities and pools there are in the sphere of influence. The number of cities on our side is more than your side, which in ancient times absolutely represented that our side was stronger than your side.
Therefore, the forces on all sides have been staring at each other's cities and pools, trying to take them by all means.
As mentioned above, war is a helpless means, because compared with negotiations, war consumes a lot of money and manpower, and it will also greatly damage its own strength. The most frightening point is that if one party and the other side are in full swing, even when all the living forces of their own family are invested, once they are attacked by a third party, it is basically dead and lifeless.
However, although it is a helpless move, the launch of war becomes a necessary means when negotiations are ineffective and other methods cannot be implemented.
However, although it is a necessary means, it is also a headache, because it takes a lot of effort to conquer the enemy city by force. Once the other side can't defend the city, the besieging side can only take encirclement measures outside, and there is no other way.
Therefore, in the city pool offensive battle, the most disadvantaged is the siege side, after all, the defending side is still the main battle, the siege side has traveled thousands of miles to the door of people's homes, eating is not good, sleeping is not good, even if the city is fully surrounded, it can only wait for the next move of the defending side, and at the same time have to be careful whether the enemy army will call reinforcements, once there is reinforcement, then they are the enemy on their backs.
Moreover, in ancient times, when the city was built, the defense problem was fully taken into account. Generally, cities and pools are built according to geographical location, which is itself set up on the main road of transportation. In terms of the city wall, when it is built, it fully reflects the defensive side, often built into a square, with a city gate on each side.
One of the four gates is the main gate, which is not only more majestic, but also has many attack facilities.
Such a city, generally does not cost a lot of effort, it is impossible to capture, not to mention that there are heavy troops guarding at key moments.
Then, since the city is so difficult to attack, why not give up, take a detour deep into the hinterland, and attack those cities with relatively low defenses? The answer is simply not possible.
There are three main reasons for this.
As mentioned above, the city itself is built according to the environment, except for the city, there is almost no way around, unless it is over the mountains and mountains.
Second, once the detour, there will be hundreds of miles more, which is very fatal for the ancient means of transportation, whether it is material supply or army transportation, it will increase the great difficulty.
Third, third, there were not many roads that could be taken in ancient times, and once the detours were made, there might be a lot of accidents, and eventually the gains would not be worth the losses.
It is precisely for this reason that even if it is difficult to attack, the ancient army will choose to attack to the death rather than take a detour.
