Before the restructuring and after the restructuring, the difference is very big, before the restructuring of the imperial school, there is not too formal academic system, although there are also a variety of subjects, students also have to learn these things, but generally self-taught, occasionally Li Xuan and several senior generals will go to class.

This is because in the early Tang Army, there were not even a few qualified middle and senior generals, let alone qualified instructors to teach them, so the early imperial academy was called learning, but it still relied more on the self-exploration of the academies.

Hao Bonian, Li Chunjing, and Fang Xitong are actually the most typical examples.

Because there is no unified school system, even if many officers enter the Imperial Academy, what they learn is very messy, some go to study the theory for a month or two, and some may study for several months.

But more of them went to study for a few months, but they didn't finish, but continued to serve in the army with the name of the Imperial Academy, and those who had free time would still go back to the Imperial Academy to study.

This was fairly common in the early days!

In the second year of Xuanping, after the reform of the Imperial Academy, everything has changed, and the academic system has become regular, and it has also been a long time, which has led to the fact that the students in the first formal class of the Imperial Academy after the restructuring have not even graduated yet!

Because after the reform of the Imperial Academy, its school system has become very long, and it takes a total of three years to complete all the learning!

At present, none of the students of the first batch of Imperial Academy have graduated, not even those who graduated early!

Because the school system of the Imperial Academy is too long, and the demand for high-quality officers in the Tang Army is also very large, taking into account the huge difference between geniuses and mediocre talents, so the current three-year school system of the Imperial Academy does not require that you have to study for three years, you can ask for an assessment in advance, and after passing the assessment, you can enter the next stage of study in advance, and even directly graduate ahead of schedule and officially serve.

This point, in fact, is not the original of the Imperial Academy, but the method of Guozijian!

The assessment system adopted by the Guozijian of the Tang Dynasty is that the newly enrolled students are in the low-level class, and after passing the assessment, they are promoted to the intermediate class, and then they are promoted to the senior class through the assessment, and the students in the advanced class can directly participate in the examination, but not everyone can directly participate in the examination, they need to pass the final examination, and they will be awarded the name of the person after passing the final examination, and then they can directly participate in the examination of the Jinshi Department and the Doctoral Department

Students in the lower and intermediate classes will be expelled from the school if they fail to pass the assessment of their own level for three consecutive years and successfully advance to the next level.

If the students in the advanced class fail to pass the final exam for three consecutive years, they will also be directly expelled from the school, but they will be exempted from the examination in the future and directly participate in the provincial township examination!

Of course, the latter two situations have not happened yet, because Guozijian has not been held for a total of several years, and the Tang Dynasty has a very large demand for officials in order to attract students, and the Tang Dynasty has a very large demand for officials, so the assessment is actually relatively simple.

The way in which the Imperial Academy can complete the study in advance by passing the assessment is also modeled after the Guozijian.

At present, in the Imperial Academy, students are in the first year of theoretical learning, and ordinary students in the Imperial Academy need to study for one year, but if the talent is high enough, if they can complete their studies in advance and are good enough, then they can apply for early assessment, but the difficulty of this assessment is more difficult than the assessment after one year of ordinary people's learning! But as long as you pass the assessment, then you can go to the army as a trainee staff officer in advance.

Even this internship stage can be compressed at present, as long as the performance is excellent, recommended by the chief officer of the internship unit, and can also pass the special difficult assessment, then you can end the internship early, and then return to the imperial school to receive the final stage of learning.

At this stage of study, it is even true to learn various theories of the operation of the large corps, but at this time, Li Xuan forcibly stipulates that this stage of study cannot be completed in advance, and those with excellent grades must also study honestly for half a year.

At the same time, the above-mentioned method of early graduation is only used at this stage, and when there are enough officers in the Tang Army in the last few years, and the demand for officers is not so great, students will definitely need to complete their three-year studies honestly.

At present, more than 10 students in the first phase of the Imperial Academy have completed their theoretical and practical studies ahead of schedule, and are currently receiving the last round of half-year study, and it is expected that in March next year, the first batch of students who will graduate ahead of schedule will officially enter the army.

And these students of the Imperial Academy who have gone through a complete and systematic study, their various theoretical levels are also higher than the students of the previous informal classes of the Imperial Academy, and their future will naturally go further than the original old man.

But this is all a matter of the future, now the officers of the Tang Army, especially the middle and senior officers, most of them are still early students of the Imperial Academy, so the quality of this group of people is uneven, but the real ability to serve as the head of the regiment is such a high-level affair, but every one of them is a talent that has emerged after the big waves.

After all, there are now more than 100,000 people in the entire Tang Army, but there are only 20 regiment commanders in the main force.

As for the group of bandit-born veterans in the Huangzhushan stage, except for a few people, most of the others have been eliminated by the big waves, some of them have been transferred to local places to serve as patrol officers, and some have been sent to various departments under the Privy Council to mess around.

But in the field troops, it is basically difficult to see the earliest batch of bandit generals, all of them are students of the martial arts academy or the imperial academy.

The Sixth Infantry Division was no exception, and Dai Liliang and several other regiment commanders, as well as the deputy regiment commanders and battalion commanders of various battalions, were basically officers who had participated in large-scale battles and had rich experience in warfare.

Even those low-level officers, most of them are from the martial arts academy, and some of them also have combat experience.

However, the quality of the officers of the 6th Infantry Division does not mean that the quality of the ordinary soldiers in the 6th Infantry Division is also good!

Not to mention ordinary first-class and second-class soldiers, even the non-commissioned officers at all levels, who are the backbone of the soldiers, have actually not participated in large-scale battles.

And this is the main reason why Cai Erhu is worried!

Therefore, in the face of the initiative suggested by his subordinates, Cai Erhu vetoed it after careful consideration, and even he was quite conservative, in order to prevent accidents on the troops on the Fengcheng side, he even urgently transferred the troops on the Fengcheng side back to Fengcheng.

This is basically announcing the tactics that Cai Erhu is about to adopt: defend Nanchang!

Even Fengcheng took the initiative to give up, after all, the important purpose of keeping Fengcheng was to maintain the logistics supply line, but if Nanchang was surrounded, then Fengcheng, the rear supply line support point, would be useless.

In addition, there is no too strong city defense in Fengcheng, and there are not many artillery, so the defense is more dependent on the support of Nanchang, but if Nanchang is surrounded, then it will be difficult to get support from Fengcheng, so it is better to send troops back to Nanchang to increase the defense force of Nanchang.

Cai Erhu has already made up his mind, so he will defend Nanchang, either until Li Chunjing's army returns to help, or until he runs out of ammunition and food!

For this reason, Cai Erhu, who was not very literate, had already asked his staff officers to help him write a few letters, and at the same time sent them to Luling and Ganzhou in the rear, and sent them back to Zhaoqing all the way, and also sent a letter to Li Chunjing.

The content of these two letters is also different.

In addition to informing Li Chunjing of the Sixth Infantry Division's decision to defend Nanchang, the letter to Li Chunjing also told Li Chunjing that he did not have to worry about the safety of Nanchang, and that he could rest assured that he would carry out the Huguang raid, and that he Cai Erhu would hold on to Nanchang until the army returned to help.

However, the letter sent to the south and all the way back to Zhaoqing was different, telling Zhaoqing that his Sixth Infantry Division would defend Nanchang to the death, and asking the Privy Council to organize reinforcements of Jiangxi as soon as possible.

After receiving the letter, Li Chunjing didn't say anything, just nodded slightly, and then said: "Send someone to reply to the letter, saying that the overall situation of Jiangxi will be entrusted to the Sixth Infantry Division!" ”

However, after Li Xuan in Zhaoqing received the Nanchang military report sent over by 500 miles, he was a little worried, and hurriedly convened the people of the Privy Council to discuss, no matter how Li Chunjing fought in Huguang, but the siege of Nanchang was a foregone conclusion, and in the face of the main force of 50,000 or 60,000 enemy troops and more guards, the siege of young and strong people was a question.

But in the face of Cai Erhu's request for rescue, Zhaoqing in the rear had no choice!

Nowadays, almost every main force of the Tang Army is already on the front line, even the Second Mixed Regiment, which was originally stationed in Qiongzhou, Leizhou, Lianzhou and other places, has already transferred troops north to Guangxi to fill the defense gap caused by the Fourth Infantry Division's stationing.

And on the Guangdong side, the second mixed regiment needs to guard against Yu Dayou's thief army on the Fujian side and the tens of thousands of Ming troops on Nanao Island, and they can't be easily mobilized.

As for the Guards, they can't be easily mobilized, because now the Guards are not only Li Xuan's Guards, but even the defense of the entire central Guangdong region, especially the Pearl River Delta.

As for other troops, there are still two supplementary brigades in Jiangxi, but these two supplementary brigades also need to be stationed in Ganzhou, Luling, and other vast central and southern areas of Jiangxi, not to mention that although these two supplementary brigades have the name of brigades, they are actually just two new battalions with establishment, and the equipment is also second-hand old equipment, and the combat effectiveness is worrying.

After thinking about this, Li Xuan found that he couldn't squeeze out the troops to rescue the direction of Nanchang!
