How long does it take to prepare for a war?

The answer is that the idea was to have it from the beginning, and it was not completed until the war was completely over, or some time after it had ended.

War, in fact, is a way to squander all kinds of resources, although some benefits can be obtained.

Li Yuanji still can't figure out what the war is about?

Who will be responsible for the fighting around, the devastated lives on the battlefield, the souls of countless soldiers, and the souls of the people?

But this is a more philosophical question, and Li Yuanji also can't understand it, and he can't understand why he himself has the idea of starting this war?

Subconsciousness? Or is it something else?

But these don't matter, the current Datang has the ability to declare war on any country in the world and defeat them.

This is not an expansion of self, but an increase in strength, in fact, within the army, there has always been a vigorous suppression of that kind of pride and complacency, for this reason, even some strange masters will often find some strange masters to pour a basin of cold water on the emotionally charged soldiers, so that they are always vigilant.

Anyway, they used all the methods that could be used, and the effect was not bad.

More importantly, since the re-enablement of Confucianism.

Confucianism has really found its place in this catastrophe, although it is not necessarily sincere, but for now, the situation is still very good.

Under Li Yuanji's deliberate authorization, Confucianism is also instilling a new concept in the soldiers.

It can also be seen as a cliché, the old vinegar is newly packaged.

Anyway, the core idea is one.

Soldiers, not to go to the battlefield to die, professional army, here is a profession, everyone is equivalent to having a stable job during the contract period.

But this job is risky, and no one can help you, the only one who can help you is yourself.

Therefore, if you train the training ground and do not despise any opponent on the battlefield, you will benefit from it in the end.

You are dead, it is your family who is sad, although the court also has losses, but in the current situation, there are people to take your place, and all the court needs to do is to wait for a few years to cultivate them, and then pay a pension for you.

Your life is your own, and you should never give your life to a place where it shouldn't be wrong.

At first glance, this sentence seemed to make the soldiers care about their lives, but after interpreting it, it turned out that it was not actually the case.

When it is time to sacrifice, it is still necessary to sacrifice, and what must be sacrificed is meaningful and effective, and the greater effect of this sentence is to remind the soldiers not to make sacrifices in those senseless places.

When a country's war machine is in motion, its efficiency is terrifying.

It is not difficult to formulate the matter of nine mobile armies to take turns in battle, you only need to take out a garrison map, and then list the time of the march, and all the problems will naturally be solved.

Cheng Zhijie, who was warned one after another, knew that he couldn't fool himself this time, so he could only cover his head and make such a plan.

Although a plan with far more results than Li Yuanji expected may seem a little difficult, it is still very effective in testing the capabilities of the troops.

"Rotation?" Li Yuanji mentioned his interest, and when he heard these two words, he became deeply interested in this plan.

"First of all, there is no problem with basic defense, and you can also see on this garrison map that the big black dots represent the nine mobile armies, and the smaller ones are the permanent troops." Cheng Zhijie put out a huge map, which is not detailed, but you can see the entire border of the Tang Dynasty, as well as all the state capitals, and the names of important regions.

This is a temporary map, so it is not detailed, but it can also be seen that every county in Datang has a garrison, which is nothing more than the number of people.

"The garrison of the mobile army is more used to deter the young, but in fact, the regular garrison is enough to accomplish these tasks. But all this is only theoretical, and how it is in practice, so far, we have not examined it.

And His Majesty put forward the idea of having nine mobile armies take turns to fight this time, so why don't we take this opportunity to also conduct a new test of these troops? At the same time, these seemingly undifficult tests can actually help them accumulate experience.

And the biggest help is to help them adapt to the new environment faster.

At present, the most suitable thing is to start with the Guanzhong area, because only Guanzhong has deployed two mobile armies, and all other regions are all the establishment of one army without exception.

And it means that the Third Army, or the Fourth Army, first entered Shu and replaced the Thirteenth Army stationed there, and the Thirteenth Army was drawn at the same time, entering Hanoi to replace the Nineteenth Army, and the Nineteenth Army was advancing eastward, taking over the Seventeenth Army stationed in Lingnan, and the Seventeenth Army went north to replace the Eighth Army stationed in Yangzhou, and the Eighth Army went north to Yanzhou to replace the Ninth Army, and the Ninth Army went straight to Haizhou, from where it boarded ships and went to the front, and after the Ninth Army withdrew, it went north to Youzhou to replace the Twelfth Army, and then the Twelfth Army went west to Zhenbei to take over the Sixth Army. The Sixth Army moved south to take over from the Third or Fourth Army, and the only thing that had some doubts at the moment was the Seventh Army stationed in the Central Plains.

Located in the middle of heaven and earth, and the previous deployment is also based there, there are two plans at the moment, one is to directly order the Seventh Army to go east, to Haizhou to board the ship and set off, and the other is to take the train to the west, starting from Chang'an and continuing downward. When the troops returned from the north of the town, they first took the train to the Central Plains and then returned to Chang'an. ”

This plan is actually to let all the troops of Datang circle around the border, which is a long-distance training to put it bluntly.

But the problem is that after a long training, they still have to go to the battlefield immediately, and after a journey of several thousand miles and a two-day sea journey, they will immediately go into battle after arriving at the front line.

Even if you have a strong will to fight, you will feel tired in such a situation, right?

If it was in peacetime, it would be nothing to do it like this, but this is in wartime, at least in Li Yuanji, it is completely a blind toss.

"Change!" Li Yuanji replied coldly.

He agrees with the rotation, but he disagrees with such a large-scale rotation.

It's like playing a soccer game soon, you can easily win the opponent, but now you have to run 10 kilometers before the game, can you still run during the race? .

This shows the importance of the railway, if the railway is connected, there is no need to worry about this problem at all, and you can get on the train and get from the distant frontier to another place in a few days.

"Then we have to implement the second plan." Cheng Zhijie shrugged his shoulders, as if to tell Li Yuanji that he had done his best.

This action was originally nothing, but in Li Yuanji's opinion, it was problematic, and he really wanted to beat this thing.

However, Li Yuanji still did not stop it, but waited for Cheng Zhijie to continue to talk about his second plan.

"Not for the purpose of rotational stationing, set off nearby, calculate the time for the garrisons in various regions to arrive in Haizhou, and the three armies in the north can directly launch an attack on land."

In other words, the core of this plan is to completely abandon the stationing of the mobile army in the inland areas, and hand over all the defense tasks to the permanent troops in various places.

Although this is their duty, the deterrent power of the mobile army is still quite strong, after all, the establishment of the mobile army is a type A establishment, and the permanent army is mainly a type B establishment, and there are even some type C troops.

If it were peacetime, there would be no problem at all with the use of these troops for defense.

However, if something happens, it will be a problem of insufficient mobility.

The concept of the establishment of mobile units comes from several rapid reaction units in later generations, and the concept is also based on the later generations, but the later generations have a relatively large room for choice.

And now, except for the Changluo line, which can be satisfied, other areas cannot be satisfied at all.

The railway network has not yet taken shape, and many are still being planned, and are not officially included in the proposal, even if they are mobile troops, their means of transportation are still war horses and feet.

This restriction is very large, unlike later generations, ordinary trains, high-speed rail, airplanes and other multiple means of transportation, which can ensure that within 24 hours, any rapid reaction force can reach any area of the country.

The current conditions are like this, higher requirements can be raised, but the reality is absolutely impossible.

In fact, the role of these mobile units is mainly to guard against emergencies in their own areas, and they can immediately support and deal with them.

On the other hand, this also revealed that the number of troops is really insufficient.

In the case that the means of transportation cannot keep up, the only way to reduce the time for troop support is to increase the number of troops and reduce the distance that troops can maneuver.

However, none of this problem can be solved now.

The two plans have their own advantages and disadvantages, how to choose, Cheng Zhijie was very smart and kicked the ball to Li Yuanji.

Li Yuanji glanced at Cheng Zhijie lightly, and saw that the thing still had an innocent expression, which made people angry, but helpless.

After thinking about it, Li Yuanji directly canceled the right to participate in the battle of the two mobile armies in Hanoi and Lingnan, they were too far away, and the situation there was more complicated than other regions, and two armies were needed to deter there.

As a result, the forces involved in the war were reduced to seven corps.

In the end, Li Yuanji chose the second plan, but he did not completely adopt it, but asked each army to leave one division at home, and the remaining three divisions were removed, and the third and fourth armies did not need to leave troops.

The only thing that can be done at the moment is that.
