When a war is over, where are there any mistakes? Wherever you perform well and what advantages the enemy has, you can record them clearly! And file is issued. The low-level officers below will understand at a glance. They will teach the soldiers and learn from top to bottom!

With Liu Pei's consent, Cao Huachun also saw the meeting. There were many things clearly written in the meeting minutes. For example, what happened in this battle under what circumstances? What were the responses? What were the improved responses? What are the benefits?

In addition, what are the records of problems? How to improve the problematic parts? For example, the small-caliber Franco cannon was included in the procurement list.

The officers asked to install such artillery in the army as soon as possible because it had suppressive firepower at close range and could make up for the problem of low firing rate of the musket. This was immediately raised by an officer to renovate the vehicle.

Since Liu Pei's officers were not from the army, they didn't know that there were things like side vans. It was only when Cao Huachun proposed side vans that everyone knew about them.

During the reign of Emperor Daizong of Ming Dynasty, Guo Deng once built a side van for defense in Datong. The shaft was 1.3 zhang long, 0.9 zhang wide, and 0.75 zhang high. The van was made of thin plates, guns were placed on top, and 10 people were arranged to use it. "When it came out, it was matched left and right, hooks and loops were connected in front and back, and the car was carried, and the equipment was also equipped with deer antlers."

Therefore, the so-called side van usually refers to a large-wheeled vehicle, with four wheels and one side is equipped with a very high and thick baffle. When necessary, it can be used to block the enemy's bow and arrow shooting. Several side vans are connected to each other and can form a relatively strong barrier. Ordinary bows and arrows are definitely impossible to penetrate.

There are shooting holes on the wooden baffle. Musketeers standing behind the baffle can shoot from the outside. The side van only needs animal power to pull it. A war horse or cattle can be used, or even mules or donkeys can be used. If you don’t even have animal power, human power can be used.

The northern wilderness of the Ming Empire was dry and rainy, and the soil was relatively hard, which was just right for the driving of a large car. The most important thing is that the side van really had the function of a car, which could pull a large amount of supplies. A common side van was transported.

There is no problem with saving 500 kilograms of supplies. One hundred such side wings can transport 500 kilograms of supplies. A side wing that can transport and fight wars is a bit like the later armored personnel carriers in terms of function.

When the Qi family army was stationed in Jizhen, Qi Jiguang personally invented that Qi's side van, which was more powerful, had many changes. It was very tall, with three floors, and seemed to be a small mobile fortress. There were more than a dozen wheels of various sizes underneath. Each floor was equipped with cannons and fire mirrors, and the firepower was very fierce. A side van could garrison fifty soldiers. This side van could be called a mobile fortress!

However, this kind of car is too expensive and has high requirements for craftsmanship. Only when Zhang Juzheng was still in power and strongly supported Qi Jiguang, Qi Jiguang could build it with human, material and financial resources. After Zhang Juzheng's death, Qi Jiguang was also dismissed, and this huge side van was abandoned.

After hearing Cao Huachun's description, the officers immediately drew a sketch and made changes according to their needs. In the end, everyone agreed that the large side vans such as Qi Jiguang were not used. As long as the existing rubber-wheeled truck was changed to a four-wheeled truck, the upper structure was slightly changed, and each car could be loaded with a Flang machine cannon. Moreover, Cao Huachun's name was recorded in the meeting minutes in a noble manner, which made Cao Huachun feel very proud!

Let me say something off topic here. It happened that someone would discuss with me the issue of four-wheeled carriages in Europe and two-wheeled carriages in China. I can tell you responsibly that it is definitely not that the ancestors of China were not smart enough and could not invent four-wheeled carriages. In fact, four-wheeled carriages had appeared in the Spring and Autumn Period, but they were not popular.

Here comes a demand issue. The reason why four-wheeled carriages appear in Europe is because the whole of Europe is a flat and spreading plain, and the terrain is almost without any ups and downs! Therefore, four-wheeled carriages are the most suitable and convenient.

China is actually in a semi-hilled area with very few plain areas. Therefore, it is most convenient to use a two-wheeled carriage. It can turn lightly up and downhill. Moreover, the Central Plains has always lacked enough horses, and two-wheeled carriages only require donkeys.

Or a mule can pull it. So, it’s not that you don’t have this ability, it’s just that you don’t have this need.

Early the next morning, Liu Pei's men rushed to Baobaoding with the wounded. They took Cao Huachun's warrant and led the soldiers from the Beijing camp to send the wounded to Baoding Mansion to recuperate. When Liu Pei returned, they picked them up.

As for Liu Pei, Cao Huachun and others were divided into several troops and began to seize the cities left after the Qing army retreat. In three days, Liu Pei "recovered" four county towns. Anyway, if Liu Pei didn't take this credit, someone else would take it. He also appointed temporary county magistrates, other officials and officials, etc. with the warrant issued by Cao Huachun.

Needless to say, except for the county magistrate, the others appointed were Liu Pei from top to bottom! Even the servants were selected by Liu Pei from the civil servants. Anyway, these civil servants were not civil servants who only used silly strength, but were relatively outstanding figures who had received militia training in various villages!

It can even be said that as long as they train carefully for a period of time, they can officially add to Liu Pei's team. As for the position of the county magistrate, Liu Pei cannot occupy it either! Because Liu Pei does not have a Jinshi in his hands, so Liu Pei only wants to completely undermine these county magistrates at the grassroots level.

However, this time Liu Pei did not stand out in person, but pushed Cao Huachun to the forefront. After all, Cao Huachun was a military supervisor, representing the emperor's will. It is most legitimate to come forward. Therefore, under the protection of the soldiers, Cao Huachun rode a tall horse and happily entered the county town that had long been recovered by Liu Pei.

Then Cao Huachun had to do it to gather the people and deal with the gentry who were still alive in the local area. Then he contacted the places behind that were not attacked by the Qing army to transport food. Finally, he read out a notice of peace and security, and then pushed the people brought by Liu Pei forward, so that they could put on their official uniforms to maintain order in the city.
