The daily marching speed was reduced to 30 miles, and all troops were strictly ordered to dig two trenches and arrange open and dark sentry posts when camping

Each regiment is equipped with watchtower cars and lookouts during the Song Dynasty. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

There are wheels under the car that can be pushed back and forth; There are pedglings on the poles for the sentries to climb up and down; The side of the vertical rod is fixed with a thick rope diagonally; The watchtower itself is equipped with a rotating shaft, which can be rotated on all sides for observation.

It is 8 zhang high, the top is placed in the plate layer, the square is 5 feet wide, the content is included in the white flag to watch the enemy's movements, and the soldiers below are informed of the enemy situation with a simple flag language.

Roll up the flag to indicate that there is no enemy, and open the flag to indicate that the enemy is coming;

If the flagpole is stretched horizontally, the enemy is close, and if the flagpole is vertical, the enemy will reach;

The enemy retreats and slowly raises the flagpole, and the enemy has retreated and rolls up the flag.

When marching and camping, observers need to be assigned to carry telescopes to the car to watch.

In order to avoid the slackness of the troops of all departments, after entering the Chengdu Plain, Yang Xuan rode a war horse to inspect the battalions every day, and sometimes inspected the open and dark posts.

When everyone saw Yang Xuan like this, everyone didn't dare to be too sloppy.

When I came to the artillery regiment that night, I saw the artillery regiment and saw Sima Mingluan, the capital of the artillery regiment, reading a book under the oil lamp while fiddling with the shells around him.

After seeing Yang Xuan come to patrol the camp, Ma Mingluan stood up, pointed to a book and said: "Zixiu, the last general is studying this cannonball, and is about to look for you, you, you are actually here." ”

waved his hand, motioned for the other party to sit down, looked at the two shells in front of him and said, "Ma Dusi, this, what's the difference?" ”

Handing over the cannonball, Ma Mingluan smiled and said, "My lord, this one is completely solid, and the other one is different, just like the earth-shaking thunder, when it lands, it will explode again." ”

Yang Xuan was shocked, isn't this a flowering bomb? Looking for it, I didn't expect that there were flowering bombs in the Ming Dynasty, I took the book and looked at the real thing, and shook my head secretly, this is probably the most primitive.

Listening to Ma Mingluan's introduction, the launch is very cumbersome

The old flowering shell, there is no such advanced fuse, the fuse used to detonate is usually a hollow reed tube built-in twist, before loading according to the distance to be shot according to the corresponding length, before firing the gun, first from the muzzle to ignite the shell fuse, and then ignite the fire door fuse to fire.

When firing, the gunpowder is first loaded into the medicine chamber, with wood in between, and an inch of soil is added, and then the shell is put into the breech, the shell is filled with gunpowder, and then separated by a layer of wet soil, and finally the muzzle is sealed with wax.

When firing, the fuse on the shell is first lit from the muzzle, and then the fuse on the fire door is quickly ignited.

According to historical records, many generals exploded when they fired this old-fashioned flowering bomb, and the soldiers didn't like it very much, except for the records in books, or a small number of physical objects, they didn't really know much.

Listening to Ma Mingluan's introduction, Yang Xuan slowly remembered the principle, shook his head for a long time and said: "Ma Dusi, you also saw that the scatter bomb has no crosshair at all, not only does it hit closely, but it also flies into the sky and almost scatters and falls, although the scene is scary, but for the old soldiers, the lethality is very weak."

Although this solid bullet can destroy the foundation, hit a person, crack the brain, and disable the body, but it is like throwing a stone, and the real effect is quite limited.

The future of artillery is, of course, this flowering shell, and of course our flowering shell is still very old-fashioned.

But as long as we continue to improve, as long as we can control its ignition of the lead in the barrel of the gun, and control the ignition of the fire signal during the flight, this flowering bomb will inevitably be generous and brilliant in the future. ”

When Ma Mingluan heard this, he nodded again and again and said: "The lesson of the adults is that we must use more flowering bombs in the future."

There are also more than 200 rounds of flowering shells in the army this time, and when I go into battle, I must use them more often. ”

After thinking about it, Yang Xuan said with a smile: "Of course, this explosion problem is very serious, although we now use an iron core copper body, although the iron mold casting water is cooled, but due to process problems, we still can't completely eliminate the problem of explosion chambering."

You can gather the soldiers, how to avoid the explosion, as long as the method is obtained, everyone is convinced, after use, you can avoid the explosion, can reduce the casualties of the explosion, we can all reward you.

Also, the problem of the fuse, the problem of the firing of the shell, and so on, all of which need to be studied attentively.

Tell the brothers that as long as you are willing to study, I can give you money to study, and after the results of your research, I will give him credit. ”

When Ma Mingluan heard this, he rubbed his hands again and again and said, "My lord, you are too good to your brothers.

In the past, people looked down on people at all when they were soldiers and ate food, but now all localities are enthusiastically joining the army, not only are they paid enough food and food for soldiers, but as long as they make meritorious contributions on the battlefield, their parents can also hold their heads up in the village.

My lord is thinking about the soldiers, and it's too late for everyone to be grateful, so why do you want adults to remember their merits. ”

Yang Xuan patted Ma Mingluan's shoulder to express encouragement, and then talked about the red-clothed cannon again, such as gunpowder preparation, in the past, utensils were temporarily loaded with gunpowder, but now the navy has been improved, first wrapped in paper, and when fighting, the lead and gunpowder are quickly put in, so the launch speed is much faster.

In addition, when fighting with the navy, the medicine room is often covered with water, and it is often covered with a glass cover, so as to avoid water splashing into the medicine room and affecting the launch.

First of all, there is also a cover on top of the red-coat cannon chamber, and it is fired normally on a rainy day.

Fired continuously, the barrel of the cannon was fired, cooled by water.

After communicating like this for an hour, and then returning to his Chinese army tent, he still felt unsteady, climbed into the watchtower car to observe the half-pillar incense kung fu, and then slept with his clothes.

Just as Yang Xuan analyzed, it was impossible for the Liukou to let the loyal army approach Chengdu City without a battle.

When Zhang Lang left, Zhang Xianzhong said to everyone with a smile: "This Yang Xuan's class has an axe, plays tricks with Lao Tzu, and sends that Zhang Hong to fool Lao Tzu, and Lao Tzu will also fool him this time." ”

Zhang Kewang, the righteous son, the supervising army, and the general of Pingdong, suggested: "Father, just now we let him think about it for three days, why don't we take advantage of his unpreparedness and send troops and horses to attack his camp."

Liaojiachang here is only fifty miles, although it will take half a day to get there, but if you want to be unaware, it will take a day and a half.

As long as we defeat Yang Xuan and drive the loyal army out of the Chengdu Plain, although the Chengdu Plain is ruined, it can also supply our army. ”

Zhang Wenxiu was shocked when he heard this, and said: "Father, Yang Xuan is extremely cautious in using his troops, and his marches and battles often set up secret posts four or five miles away, and set up open posts two or three miles away, and it is even more difficult to sneak attack his troops.

Although Yang Xuan is strong, his troops are only more than 20,000 people, and there are 150,000 people in Chengdu alone. ”

Zhang Kewang was dissatisfied: "Although what General Funan said is reasonable, it is enough for me to conquer General Dong with a knife to defeat Yang Xuan."

The whole army pressed up, do you think Yang Xuan didn't expect that his troops had just come out of Yunding Mountain, if our army approached, they would immediately retreat, leaving a small number of troops to garrison Yunding City, and then lead the army to flank our army's rear road, so our army will undoubtedly be defeated. ”

Genting City is the strategic road from Chengdu to Tongchuan Prefecture, and it was also lost under Zhang Wenxiu, and now when I heard Zhang Kewang say this, I felt ashamed, but I still admonished: "Father, Yang Xuan is quite cautious in using troops, and it is even more difficult to succeed in the night attack." ”

Zhang Xianzhong fell into contemplation, and Wang Zhaolin, the prime minister of the left next to him, came out and admonished: "General Funan, if you allow the loyal and righteous soldiers to come to the city, this will not only chill the hearts of the soldiers of our three armies, but more importantly, the Shu Fang will inevitably rebel again. ”

Zhang Wenxiu shook his head and said: "Having said that, we have 150,000 troops in Chengdu City alone, and if we wait for the loyal and righteous soldiers to come to the city, we can surround and annihilate them." ”

Zhang Kewang sneered: "General Funan, you and Yang Xuan have fought a lot, all of them have lost their armor, if they are annihilated, you still need to wait for me to make a move, and you still need to wait for my father to make a move?"

Yang Xuan only needs to move the battalion forward for twenty miles, with the Xijiang River as the boundary, and from time to time send troops and horses deep into the city of Chengdu, so it is inevitable that the whole Sichuan will be shaken, and at that time the morale of our Great Western Army will be low, do we still need to move the capital? ”

Zhang Wenxiu was speechless and silently retreated to the side.

Zhang Xianzhong immediately ordered Zhang Kewang, the general of Zhengdong, to lead an army of 20,000 to attack the loyal army, and ordered Zhang Nengqi, the general of Zhengbei, Wang Shangli, the governor of the Chinese army, and Feng Shuangli, the governor of the rear army, to lead an army of 30,000 to respond later.

A few months ago, Zhang Nengqi, the general of the expedition to the north, and Feng Shuangli, the governor of the rear army, led his troops to conquer Cao Xun, the general of the Ming Dynasty in Ya'an, western Sichuan.
