How was the military necessity formed, can t it be bypassed, why do you have to fight down?

The only way to go" will definitely be around! If you can get around it, you don't have to go through it.

Strategic locations are usually divided into two categories: "pass forts" and "towns". In general, the pass cannot be detoured, and the city must be sieged. Let's talk about passing first.

The passes are basically built according to the terrain, and most of them are built in ravines or riversides, depending on the danger. The so-called "one person can't open the off". Because there are mountains and rivers on both sides of the barrier, the attacker cannot pass through the pass without wings.

So, as long as you hold the passes and fortresses, you can keep the enemy out. (There are two passes in eastern Shaanxi: Hangu Pass and Tongguan Pass.) The pass is bordered by the Qinling Mountains in the south and the Yellow River in the north.

If you want to enter the pass from the east, you have to go through both gates. (From this perspective, Tongguan's location is easier to understand, as it is located between the Qinling Mountains and the Yellow River, the eastern gate of western Shaanxi Province.) ）

Shanhaiguan is located in Yanshan in the northwest and Bohai in the southeast. You can walk from this entrance. ）

Yanshan Shanhaiguan).

Since the pass cannot be bypassed, can those important towns be bypassed?

The answer is the same.

In ancient times, the most important problem for marching operations was "logistical supply". Especially for the infantry, the security of the supply lines is very important.

In ancient times, as long as you capture a city, you can control a large area around it, establish stable supply points, and shorten supply lines. Moreover, the city is protected by high walls, and if the attack is not good, you can also enter the city defense.

However, the ancient walls were so terrifying that even with guns, it was difficult to attack a heavily fortified city. In many sieges, faced with high walls, the attackers often had no choice but to seal the city with iron barrels, cut off the city's food**, and starve the defenders to death.

But if there is enough food in the city, even without foreign aid, there is absolutely no problem in preserving it for five or six years. And because the groundwater in China is shallow, you can dig a well in the city center to get water, so you don't have to worry about drinking water. (Today, Datong is one of the nine faces of the Ming Dynasty.)

Historically, the city of Datong has rarely been attacked from the front. ）

Since then, the siege has been a huge problem. But it doesn't matter how much trouble you have to fight in this city.

But if you retreat from the predicament and choose to take a detour, it will not only mean that your supply lines will be stretched, but you may also be attacked by enemies behind the city. At that point, you'll be very passive.

The military must pass through the place because the place that must be passed during the war cannot be bypassed, and it must be fought down in order to pass through this place, otherwise it will not be able to pass.

In short, the strategic and military significance of this place is very important, it must be fought, and this place has a decisive role in the direction of the whole war.

On the one hand, the military must pass through the natural geographical environment, on the other hand, because of the formation of the towns established by people later, can not be bypassed, the military must pass through the place is an important factor in determining whether the war can be successful, once the loss of the must pass, it is likely to be passive.

For the infantry, the safety of the supply line is very important, if the battle line is too long, the food and grass are not enough, it is easy to fall into a disadvantageous state.

In fact, when marching and fighting in ancient times, people had to lay these places because the geographical location of these places was really important, and such roads were relatively flat roads at that time. Because in ancient times, when marching and fighting, the requirements for roads were also very high, such as these roads should be flat and free of debris. But after all, there is a certain limit to the government's money, and he has no way to spend money to open up another necessary road, because it takes a lot of money to open up a road, and at that time, the money was used to march and fight, so there was no money.

Even if they still had some money at the time, they would spend it on a knife edge. And if they were allowed to occupy these places that had to pass through at that time, then they could obtain some management rights of this place that they had to pass through, and this place could be regarded as their own, so they could use such a road for transportation without building a new road. This road was built by others before, and it didn't require them to spend some extra money to build, so it was an empty glove white wolf behavior.

And if they had attacked these places at that time, then they could use this place as their own military fortress, and they could better defend this place. After all, if everyone else takes this path, they can collect some tolls or do some offensive activities against the people who come and go. In fact, these trails were also used as a relatively important place to transport things at that time, although people could climb some mountain roads, but these things could not be passed by horse-drawn carriages through such rugged mountain roads.

If you attack such a place at that time, then you will be more timely in transporting grain and grass, as well as supporting your own army, and you can also intercept some of the enemy's grain and grass, and even the enemy's army, which is why you must conquer this necessary place.

It's like playing Honor of Kings, you have to go through the river when necessary, but do you know if there are enemies in the grass? Therefore, taking the necessary places before the battle can hide yourself well and attack the enemy to achieve victory.

If you want to achieve other strategic goals, you will have to take a detour, and if you take a detour, you will waste time and delay the fighters. And you can also control the surroundings, so that your troops can replenish food and grass faster.

Because in battle, you must knock down the places you must pass, and if you don't do so, your rearguard will not be able to catch up.

The main thing is to ensure the need for victory in the war; On the one hand, it is convenient for transporting military supplies and reinforcements, and on the other hand, it is convenient for retreat, otherwise it will be surrounded and there is no way to retreat.

Because only when this is the case, can you ensure the way of your retreat, and you can make yourself safer.

Most of the places that must be passed through are places with good economic development, and they belong to the places that must be passed, and they are also convenient for combat, such as sneaking up on enemy troops, or carrying out ambushes.

To be sure, no. First of all, if it can be bypassed, it cannot be called a necessary road and a necessary place. Secondly, these roads are usually close to the rivers, and these rivers were usually not easily passable before, so they can only be passed through these places.

The necessary places cannot be bypassed, these are places of great strategic significance, and they are important towns that can control the surrounding areas, and they cannot be bypassed.

It certainly can't be bypassed. Because other places have not been developed, they are all barren mountains and mountains, so they cannot be bypassed.
