"A whole army." When Zhu Youjian thought of the man in Yunyang, his face lit up.Li Laiheng, who is said to be fighting guerrillas in the mountains of Shangluo, has actually been constantly expanding his strength.Coupled with Zhu Youjian's unlimited support, Li Laiheng is the fastest rising general.

The next day, the military expansion order signed by Zhu Youjian and the Sichuan Army deployment and combat order signed by Deng Zhirong were issued.

The Eighth Army, Tenth Army, and No.11 Army expanded on the spot.The number of the military department remains unchanged, but the brigade has been expanded into a division, and it is the establishment of a type A division.In addition, three reserve divisions will be formed in southern Sichuan to guard southern Sichuan as local garrison troops.In fact, these three divisions are the expanded reserves reserved for the Ninth Army and the No.12 Army.

The main force of the naval division has already started to go north, and the No.12 division, which has completed the refitting, is the main force, and the artillery division has begun to move to Hechuan.

What Zhu Youjian wanted was to start the war in Sichuan before Dorgon launched the Battle of Huaisi.If the war in Sichuan drags on for too long, Daming cannot withstand the attack of Houjin's 70 troops with troops from the south of the Yangtze River.

Even if Houjin doesn't occupy Jiangnan, it only needs to destroy Jiangnan, and Daming won't be able to recover in a short time.This battle is not a question of whether the Houjin can be defeated, but how to disintegrate the destruction of social productivity by the Houjin.Zhu Youjian did not have the energy to restore the productivity of the Central Plains for decades.

At the same time as the war started, the production machinery and technicians mobilized from various factories in Nanjing also began to transfer to Sichuan in a planned way.

Zheng Chenggong, who was far away in Fujian, received a letter from the emperor asking for help. The main idea of ​​the letter was to ask the Fujian Navy to dispatch [-] sailors and several warships and transport ships to reinforce the Yangtze River Navy.

"The surname of the country, shall we give it?"

"Yes, give as much as you want. If the imperial court is defeated, can my Zheng family survive?" Zheng Chenggong did not hesitate, and immediately sent a third of the sailors and ships to the north.As a result, the combat power of the Fujian navy was greatly reduced, and they faced a large defensive area, basically unable to help Shi Lang resist the Jin Navy's attack on the Yangtze River estuary.

Shi Lang encountered a lot of pressure. Although his warship was very powerful, he could only protect the mouth of the Yangtze River.The production of Nanjing Shipyard has been supplying Sichuan, and there is no navy in the south of the Yangtze River to expand its production capacity.

In this huge layout jointly constructed by Zhu Youjian and Zuo Maodi, the places where the navy is needed are the Minjiang River, Tuojiang River, and Jialing River in the west; the Han River in the middle and the Yangtze River in the east.

At the same time, Qin Liangyu, who exists as a symbol, also issued a call to call on the people in the entire Three Gorges area to join the ranks of trackers and contribute their own strength to encircle Daming.

In Daming, except for some scholars in the south of the Yangtze River who watched with cold eyes, unprecedented unity was formed in other places.

Chapter 325: Forced to retreat Zhang Kewang

If it is said that the Luzhong Army's most powerful is stabbing, then the Sichuan Army's most powerful is actually not the flintlock, but the cannon.In this era, the per capita share of cannons equipped by the Sichuan Army has reached a frightening level.

The artillery division directly under it is equipped with 240 cannons. This is not counting the cannons equipped by each army. Almost every regiment has two cannons.

If it is placed in later generations, this is not worth mentioning at all, but in this era, it is the existence of local tyrants.If it weren't for technological innovation, Zhu Youjian really couldn't afford to equip artillery of this scale.

However, because the bomb technology is not up to standard, the power of the cannon cannot be exerted, but the number is scary.For this reason, the research and development department of the Ming Dynasty military industry directly gave up the Francophone, and instead focused on the research and development of casting Napoleon guns and shotguns and chain bombs.

At the same time, he is still working on a new type of mortar, Zhu Youjian calls it a mortar, and is waiting for a breakthrough in fuze technology.

The biggest breakthrough in the existing fuze technology is the hand grenade, which is also the simplest pull-fire fuze. The by-product is the civilian match technology.

The detonation speed of nitrocellulose is higher than that of black powder, but the explosive power is not much stronger than that of black powder.If a large amount of black powder is changed into nitrocellulose, the cost is too high and it is not cost-effective.

As a result, local tyrant Zhu Youjian continued to use black powder for cannons, but changed muskets to nitrocellulose, considering the material problem.The direct consequence of this move is that the effective range of the flintlock has been increased to 200 meters, and the longest range has reached 400 meters.

If there is rifling, Zhu Youjian believes that doubling the effective range is not a problem.Moreover, rifling the gun barrel is not a profound knowledge. There are a lot of rifling machine principles in the later forums, and Zhu Youjian can figure it out at any time if he wants to.

Rifling is actually a tasteless existence for front-loading guns, and it is more suitable to use it when breech-loading guns are not developed.Zhu Youjian didn't want to play Minnie bombs at all.

So where is the difficulty of the technology tree?

Or basic science, materials technology and chemical engineering.

It is the type of steel, the emergence of new chemical synthesis materials, and every breakthrough in processing precision.

Every innovation of these things depends on the accumulation of money and the hard work of human hands.Making a flintlock doesn't mean you're invincible, and pulling out the rifling doesn't mean you're number one in the world.Among them, the barrel is made of steel, which cannot be solved by simply training the steel.

Take the flintlock guns used by the regiments of the Sichuan Army as an example. The steel used for the barrels has not exceeded the quality of hand-forged by old craftsmen.Because of the high-speed drill bit, boring machine technology, etc., the technology has been tied.And because of the nitrocellulose propellant, the breakthrough was achieved.

That is to say, Houjin can also make flintlock guns now, but their equipment speed will be much slower. They are all forged by hand. It will take several years to equip 10 flintlock guns.

As for Paogang, Zhu Youjian estimated that he would have to spend a million taels of silver to see if he could get some results.

……

From the moment Zhang Kewang received the news of Zhang Xianzhong's defeat, he began to panic.He knew that the price he asked the Emperor of Ming Dynasty was too high, and he acted in front of others like a clown before.

He couldn't beat Diaoyu City at all, it just increased the opponent's disgust for no reason.

Zhang Kewang failed, and he was unwilling to fail.He is not reconciled!

"King Pingdong, what shall we do?" Bai Wenxuan pointed at the ever-increasing Ming officers and soldiers in the distance, feeling a little nervous.

Needless to say, the Sichuan army has already started preparing for a counterattack, and the ships transporting troops are continuously approaching the shore, and there are already densely packed soldiers standing on the shore.

"It's a mule or a horse, pull it out for a walk. We can't retreat like this, or we will be looked down upon by others." Zhang Kewang refused to accept it. He wanted to take a gamble, and only if he won the fight would he have the right to speak.

At dawn the next day, starting from the Diaoyucheng pier, one after another small boats began to cross the river in an orderly manner.There are more than a dozen warships in the upper and lower reaches of the river, which are responsible for covering the erection of the pontoon bridge.

The Western Army had nothing to do. Their soldiers charged to the shore and could only be bombarded. The only small artillery could not reach the warships of the Sichuan Army Navy.

In just one hour, when the sun rose one pole high, the pontoon bridge was completed.All the Western Army in Hechuan City looked at the bridgehead in horror, a big battle was just around the corner.

"Boom, boom, boom..." The first regiment crossed the bridge first, and formed a skirmish line to control the range of 500 meters from the bridge head.At this time, the artillery fire on the warship never stopped.

Immediately afterwards, a brigade crossed the pontoon bridge and began to form a company at the head of the bridge.The queue has three layers, and each layer is staggered in the shape of a character.The nine formations form a line, which is [-] steps wide.

Obviously, the No.12 Army formed the first volley formation on the land of Ming Dynasty.The bugle controls the army's retreat, and the whistle controls the formation.Without European drumbeats, the footsteps of the Sichuan soldiers followed the sound of whistles in unison.

Zhang Kewang also understood that the opponent was disdainful of attacking the city and directly asked for a field battle.It is the most straightforward provocation, even with humiliation.

Zhang Kewang thought it was over like this, but when hundreds of cannons appeared neatly behind the array, revealing the dark muzzles, he knew it was over.

Sure enough, immediately afterwards, the Ninth Army appeared on the right wing of the formation in the formation of large firearms.

"Send 5000 people to rush there first." Zhang Kewang said, pointing to the opponent's battle formation.

From leaving the city to the opponent's battle formation 800 meters away, the Five Thousand Western Army habitually ran to a position 500 meters away to form a formation and prepare to charge.But before they finished forming their formation, the Sichuan Army's cannons rang.

They have reached the effective range of the Sichuan Army's cannons, which is a typical death-sending action.The Sichuan army doesn't talk about style, as long as they find an opportunity, they will fire immediately.

Before these people could successfully form a team, a row of iron bullets flew over from the opposite side, plowed through the crowd whistling, and took away a piece of broken arms and hands.

"Oh my god..." The Western Army was in chaos, and the formation could not be organized at all.

"Idiot. To send another thousand-man team to reinforce, we must form a horizontal line and spread out to avoid shells." Zhang Kewang cursed.

It was really unfortunate that the Western Army was killed by a burst of artillery fire and hundreds of people before it attacked.

Thousands of people pulled out a 500-meter-wide skirmish formation at a depth of 500 meters. The density is not too big or small for this era.If it is an ordinary firecracker, I am afraid that the Western Army can charge to a distance of 50 meters, and then rely on bows and shields to cause damage to the opponent.

If you were a little stronger and stepped forward desperately, you would be able to break the opponent's musket array.At least Zhang Kewang thinks so.

It's a pity that the Sichuan Army didn't do what he wanted. The Western Army ran to a distance of 200 meters, and the Sichuan Army opened fire.The gunfire was dense and orderly.What the Western Army couldn't understand the most was that there was no smoke after the Sichuan Army's gunshots.

This is fatal, there is no smoke blocking, the gunman's line of sight is terrible.This 200-meter distance became the road of death for the Western Army, and layers of corpses fell on the way to charge.

The western army finally rushed to the front of the Sichuan army, and they were greeted by gleaming bayonets.The Western soldiers turned their heads and saw that there were not many people left behind.
