My life skills in Daming Liver

Li Yangong felt a completely different style among Chen Linjun.

Chen Lin's style of leading troops in war is one of stability.

Marching forward, setting up supply routes, all plans have two sets of plans, and even a third set of remedial plans.

And Chen Lin's requirements for artillery firepower supply were extremely high.

For example, he required the artillery of the Fifth Brigade to carry twice as much ammunition as other brigades, and required logistics to deliver artillery supplies from Xuzhou to the front within five days.

Thanks to the construction of the railway in Xuzhou, Chen Lin requisitioned vehicles and ships throughout the Huaibei region to provide artillery and ammunition supplies to the front line.

Li Yangong has never fought such a rich battle!

The soldiers of the Ding'an Regiment, including Li Yangong, thought that Chen Lin was too cautious at first, but soon they discovered that Chen Lin was not cautious at all.

The Ding'an Regiment fought in Guangxi and Annan before. Whether it was the chieftain army in Guangxi or the army in Annan, their fighting will was not strong, and their weapons and equipment were also very backward.

Often as soon as the Ding'an Regiment fires artillery, the enemy begins to panic and is ready to surrender the next day.

But the Ming army in Henan was different.

The father and son Chen Yiqin and Chen Yubi are still very good at civil affairs. They also attach great importance to the construction of the New Army. Henan's population is well established, so the Henan New Army can become the second strongest army in the north after the Ming Dynasty New Army.

On the way to Suiyang, Li Yangong saw the combat effectiveness of this Ming army.

Along the way, the Ming army built fortifications, and even if they knew they could not stop the new southeastern army, the Ming army would partially destroy the roads and infrastructure before giving up the front.

Therefore, although the journey from Xuzhou to Suiyang is not far, there are constant battles along the way.

Chen Lin's steady style also played a role. After taking control of a place, Chen Lin would have the army clear out ambushed bandits and landlords to ensure the safety of logistics channels.

Therefore, the Ming army's attacks on the supply lines of the New Army in the southeast were unsuccessful.

However, as the front stretched, the problem of the supply line was exposed. Chen Lin needed to spend more troops to guard the supplies along the way, while Chen Yiqin only needed to transport the supplies to Suiyang and then defend Suiyang.

When the Xuzhou army was about to arrive in Suiyang, the atmosphere in the military camp became even more tense.

When he saw the Suiyang city wall, Li Yangong couldn't help but gasped after seeing the dense fortifications.

Chen Lin once again convened regimental-level officers and combat staff to discuss the strategy for attacking Suiyang.

Li Yangong walked into the headquarters and saw several people wearing scribes' clothes. It was obviously a combat meeting, so why were there still non-military people participating?

After Li Yangong sat down, Chen Lin said:

"These are professors from Tiangong Academy. They are here to guide us on the battlefield."

A professor from Tiangong Academy?

Li Yangong was a little surprised. The professors at Tiangong Academy were not professors at the Military Academy. How could they still guide combat operations?

After Chen Lin waited for everyone to sit down, she began to say:

"Everyone has also seen that this is the result of the fire reconnaissance of Suiyang. Chen Yiqin dug six trenches in Suiyang. These trenches were connected from front to back. He also set up three artillery positions and cut off the waterways near Suiyang."

What a desperate defense line. Soldiers are hiding in trenches. Ordinary shelling cannot hurt the soldiers at all. If they want to occupy the trenches, their own soldiers will have to brave the enemy's artillery fire and rush into the enemy's trenches. The losses in this kind of combat are really huge. too big.

One or two trenches can still be filled, but how can six trenches be filled?

Chen Lin also had a headache. He knew that Chen Yiqin attached great importance to Suiyang's defense, but he didn't expect that he would attach such importance to it.

The regiment leaders, including Li Yangong, were silent. Apparently, there had never been such a difficult battle since the Southeast began to use artillery and artillery.

Chen Lin saw everyone was silent and then said:

"Since none of you can do anything, I'll tell you what I can do."

"Dr. Xu?"

A young scribe stood up and introduced himself: "Generals, I am Xu Jin, a doctor from the Department of Mathematics of Tiangong Academy. The Ministry of War asked us to report on the front line."

"To make a long story short, this time the combat plan is called 'Xu Jin Barrage', and what follows is our combat plan."

"Xu Jin barrage?"

The generals present were all dumbfounded. What kind of tactic was this?

Xu Jin said: "Everyone knows that the artillery fired by the artillery moves along a fixed trajectory. This is related to the initial speed of the artillery and the launch angle. The trajectory of this artillery shell is called a parabola. How to calculate this parabola has been used in the artillery The artillery fire parameters summarized by the War Department are simplified formulas for simply calculating the artillery fire trajectory."

"In other words, our artillery can control the impact point of the artillery shells."

"The artillery fired together can form a barrage of artillery shells. As long as the artillery keeps firing salvos, this barrage can advance steadily like a wall, and our infantry can hide behind this wall. "Behind the Wall', occupy the position plowed by artillery fire."

"This is Xu Jin's barrage tactics."

Li Yangong and all the frontline commanders were a little dumbfounded. The tactics introduced by Xu Jin seemed to be really feasible?

However, the requirements of this tactic are too high. To allow the infantry to march between artillery barrages, it requires the artillery and infantry to cooperate tacitly to every second. If either party makes a mistake, it will be its own artillery bombing its own infantry.

In addition, to form an artillery barrage, artillery requires continuous firing of artillery shells, which also has very high requirements for artillery. The time of each launch and the landing point of the artillery must be exactly the same to achieve such an effect.

Li Yangong finally understood why Chen Lin had to hoard so many artillery shells on the front line and conduct so many joint march drills and exercises along the way. It turned out that it was all for this tactic.

And if there is anyone in the world who can execute this tactic, it is only the army in the southeast.

Because only the army in the southeast has so many artillery and well-trained infantry, and only the southeast can provide accurate timekeeping pocket watches in the hands of the most basic commanders.

No one can refute it tactically, the rest is execution.

Doctors like Xu Jin from Tiangong Academy developed a more accurate method for calculating artillery barrages and used arithmetic to calculate a set of detailed time nodes.

This node includes the time for firing the artillery, the time for the infantry charge, and the time for the next round of barrages to adjust and load the artillery. Every time node must be precise and consistent.

In this battle, the Fifth Brigade also used new artillery shells shipped from Nanjing. This kind of artillery shells will explode after landing and can effectively kill enemies in the position.

On March 7, the general offensive began.

Li Yangong walked to the battlefield and took out his pocket watch:

"Everyone, watch!"
