"Work has finally started." A captain said to his companions. Behind them were the most powerful weapons of the Chinese Army, an ultra-long-range train gun modified from a 12-inch 40l naval gun and a special concrete armor-piercing artillery weighing 405kg.

placed in

On a circular rail disc, in order to have a decent shooting angle, and behind it is a section of the transport vehicle, which is equipped with a basic cannon and propellant, and there is also a temporary small house next to the cannon.

There are items such as phones and maps inside.

The Chinese Army actually started attacking the Nerchinsk fortress group very early, but at that time they were all probing and harassing attacks, used to determine the opponent's heavy firepower points and fortress layout, and also to contain the opponent. At the beginning

The Russians and the Chinese Army exchanged fire, but then they discovered that the largest caliber artillery used against the reactionaries was only 6 inches and did not have much impact on the fortress, so they didn't bother to bother with it. After all, the Russians did not have enough ammunition.

available for consumption.

And now, the long-hidden 12-inch heavy train gun has finally shown its sharp teeth. The entire heavy artillery group responsible for opening the gap from the southeast has as many as 12! According to the results of the Chinese Army's advance reconnaissance, this area

The opponent's artillery was only 12 8-inch guns, 4 10-inch guns, and some other small and medium-caliber artillery. If it weren't for the fact that the cover of the opponent's artillery was covered with more than 2 meters of reinforced concrete, the Chinese Army would not have gone to such trouble.

.

As the general attack order was issued, a company of infantry began to operate this heavy artillery to prepare for battle. Each round of the slender 12-inch cannon was lifted out of the medicine cart through the slide, and then was hoisted onto the artillery cart by a crane. Then it was loaded into almost

In the horizontal barrel, there are two propellant packs. The front one is wrapped in silk. The back one is wrapped in a brass shell. Finally, there is a lock. The gun adjusts its aim.

Three signals rose into the sky. In the next few seconds, the ground was shaking. Smoke and fire instantly filled the entire firing position. 12 artillery pieces were deployed in 6 positions, and clouds of dust were scattered in the huge sky.

The force flew up into the sky. From a distance, the entire artillery position was covered in thick smoke and fire. The piercing whistling sound instantly filled the sky above the battlefield. Cannons that heralded destruction flew out towards the target in the distance.

And the other party hasn't reacted to all this yet.

Most of the Russian army's heavy artillery is usually placed in gun rooms. These gun rooms are almost half-buried underground. They are connected to the semi-open gun pool by guide rails. In wartime, these artillery will be pulled to the gun pool through the guide rails.

Then fight, the whole process takes about fifteen

About minutes. But now, just as a group of Russian soldiers were struggling to pull the heavy artillery into the position, they suddenly felt the entire gun room shake violently! Then a huge dark red object penetrated from the top, and then hit the passage directly.

On the rail ahead!

"I felt like an earthquake at that time, and several of my friends and I were knocked to the ground. While falling to the ground, I vaguely saw a lot of gravel and iron fragments flying forward. I subconsciously

He rolled and hid behind the cannon, and then there was a pounding sound like a heavy rain coming from the cannon.

came. And a big hole was drilled in the reinforced concrete dome above the passage in front of us. Thank God, this cannon was dumb! But even so, the entire passage was still destroyed. The artillery method reached the battle position, and my battle was not over yet.

It's over as soon as it begins!" a Russian artilleryman recalled at the time.

But not all Russian gunners will be so lucky. There will always be someone who will be tragic. No, an 8-inch cannon has just been moved to the gun position, and the bracket has been placed and is being aimed. The delivery vehicle behind will also fire a round.

The gun was taken out of the magazine and sent to the side of the gun emplacement. Under the urging and threats of the officer, the Russian gunner had just sent a cannon to the breech. A 12-inch gun hit the rear of the emplacement without any warning.

On the concrete lid, powerful impact

The impact directly removed half of the concrete cover from the top, and then the gun continued to move forward and landed on the propellant transport truck below! With an earth-shaking loud noise, a fire dragon quickly rushed towards the gun emplacement and powder warehouse.

Spread. The small and airtight air force cannot release powerful energy. The high-temperature and high-pressure gas and heat generated continue to explode in the entire transportation channel. Sections of semi-buried bunkers collapsed amidst the explosions one after another.

Although the fire dragon that finally led to the magazine was blocked by a thick fire door, the flames and shock waves leading to the gun position could not be blocked. A violent torrent of flames instantly filled the entire gun pool, and after a while, the entire gun pool became

A burning sea of ​​​​fire. This scene is repeated on the battlefield. Not only the Russian fort that achieved calibration suffered fatal

The blow hit the fish pond, and even some nearby buildings were affected. A cannon fell on the top of a bastion, and the hardened armor penetrated like butter. Then, under the action of the fuse, nearly ten kilograms of

The explosives tore the body into pieces, and a firestorm broke out throughout the bunker. The bones of a company of Russian troops in the entire bunker were instantly found![

It is not that the Russian army did not counterattack, but under the continuous saturation bombardment, both the semi-enclosed gun nests and the open-air gun pools were almost covered by rain. The power of the 12-inch heavy artillery can almost guarantee the destruction of everything it encounters. Russia

The artillery nests built with great effort are extremely vulnerable to special armor-piercing attacks. Even if individual artillery nests are more powerful than

Although it was not destroyed, it does not mean that the artillery's servo facilities can also withstand such a blow. After firing less than 4 rounds, a 10-inch heavy howitzer found that its transmission channel was hit, which was several meters long.

The collapse of the cannon completely cut off the source of ammunition. Although the artillery was not destroyed, it was absolutely unable to fire a single shot at this time!

In this way, the train artillery unit of the Chinese Army slowly cleared the Russian heavy artillery positions under the guidance of the airship. At the same time, a large number of 8-inch cannons also began to continuously suppress the remaining long-range artillery of the Russian army. This preparation process continued for the entire time.

One day, when night fell, the artillery fire of the Chinese Army finally stopped. Only a few artillery pieces were left to perform harassing shooting at night.

"How are the preparations going?" Nie Shicheng asked in an underground bunker. "It should be almost done. If nothing else happens, the Russians will mobilize a large amount of manpower to the southeast tonight to reinforce the damaged offensive. Personnel from other places

It should be relatively reduced. And our disruptive bombardment will last for one night. The other party should not be able to hear it." An officer said carefully.

There is a saying that a fortress is always breached from the inside. This sentence is absolutely correct, regardless of whether the fortress is a real fortress or a virtual one! After carefully studying the terrain and geology of the Nerchinsk Fortress Group, the Chinese Army discovered that in

The northeast corner of the Nerchinsk Fortress Group is a swamp. This area is said to be very unfavorable for entry.

Therefore, the Russians placed key facilities such as drug depots and power stations here. And in order to prevent being attacked by long-range heavy artillery, the drug depots were placed about 3 meters below the soil layer. In addition to the 3 meters of soil layer, there are also

There is a 2-meter concrete dome. Although the power station is not so well protected, it is very hidden.

However, some areas underground in this swamp are more suitable for digging. Originally, the Chinese Army had given up on this area. After all, even if it used heavy artillery to knock open the opponent's cement box, the troops could not trek through the swamp, and from the surface

It seems that there are no offensive facilities such as heavy artillery positions in these places, so at the beginning it was just a auxiliary attack direction. The original plan was to dig a tunnel and sneak into the opponent's position to cause trouble.

But who knows, when the engineers successfully passed through the outer trenches, barbed wire and sparse bunkers, a thick reinforced concrete foundation appeared in front of people! And the depth and width exceeded the initial expectations. From the initial gun nest

From the later underground soldier caves to the final large-scale underground facilities. Nie Shicheng and others did not understand what it was until the end!

Until one day, when the Chinese Army was engaged in an artillery battle with the opponent, the airship responsible for reconnaissance from the air discovered that there were many people and vehicles coming in and out of the northeast. And the entrances were very hidden and narrow. When this information was sent to Nie Shicheng's desk,

Nie Shicheng's first reaction was that this should be an important material warehouse for the Russian army, and it might even be a medicine warehouse! When he thought of this, Nie Shicheng's heart couldn't help but beat wildly!

If this medicine depot can be taken away, the entire attack process will be shortened. But obviously, at this position, due to terrain problems, it was not used as an attack direction at first, so the railway was not paved, and the train artillery would naturally pass.

No. Relying on the 8-inch cannon to knock out the opponent's ammunition depot, it seems impossible! As for sending infantry and tanks? Well, just think about it.

Just when Nie Shicheng was about to give up the plan, Nie Shicheng was overjoyed by the information from the engineering troops. He really didn't expect that because of his harassment plan, the engineering troops had dug tunnels near the opponent's underground fortifications. But think about it, as early as the war started

At the beginning, the Chinese Army started digging when they were resisting Russian cavalry harassment in their own rear. It has been digging for several months now. The total straight-line distance is less than 3km, and they have already dug under the opponent's wall.

However, this is because Nie Shicheng does not know much about geotechnical engineering. This tunnel is not straight. In order to prevent collapse and underground water seepage, the direction of this tunnel is tortuous and winding. Although it is quite difficult to walk along the way,

After all, we have to go to the other side's large-scale underground construction

At the bottom of the matter, looking at the thick foundation and the reinforced concrete part above, the engineering major in charge of the construction had mixed feelings. What is behind this load-bearing wall? No one knows, but I hope it is not some underground barracks.

What a valuable thing.
