"It's finally time to start." A CAPTAIN SAID TO HIS COMPANIONS NEXT TO HIM, AND 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 PROJECTILE WEIGHING 405KG. The cannon was arranged on a circular rail disc to allow for a decent angle of fire, while behind it was a bomb cart with a base number of shells and propellants, and a small makeshift house next to the gun with items such as telephones and maps.

In fact, the Huaxia Army began to attack the Nebuchu fortress group very early, but at that time, they were all tentative and harassing attacks, used to determine the opponent's heavy firepower points and fortress layout, and also to contain the opponent. At first, the Russians and the Chinese Army fired at each other, but then found that the largest caliber artillery used against the reaction was only 6 inches, and it did not affect the fortress too much, so they did not bother to care, after all, the Russians did not have enough ammunition to consume.

And now, the long-hidden 12-inch heavy train gun has finally shown its sharp teeth, and the entire heavy artillery group responsible for opening the gap from the southeast is as many as 12 guns! According to the results of the Huaxia Army's preliminary reconnaissance, the opponent's artillery in this area was no more than 12 8-inch guns, 4 10-inch guns, and some other small and medium-caliber guns. If it weren't for the fact that there was more than 2 meters of reinforced concrete on the cover of the opponent's artillery, the Huaxia Army would not have worked so hard.

With the order to attack was given, a company of infantry began to operate this heavy gun and prepare for battle. A slender 12-inch shell was lifted from the ammunition truck through a slipway and then hoisted onto the gun truck by a crane. This was followed by an almost horizontal barrel, followed by two cartridges, the first of which was wrapped in silk. The latter one is wrapped in a brass case. The last is atresia. Artillery adjusted aiming.

Three flares rose into the sky, and in the following seconds, the earth trembled, and puffs of smoke and fire instantly filled the entire firing position, 12 artillery pieces were deployed in six positions, and clouds of dust flew into the sky under the impetus of a huge force, and the entire artillery position was covered with smoke and fire from a distance. A piercing whistling sound instantly filled the sky above the battlefield. A devastated cannonball flew towards a distant target, and the other side had not yet reacted to it.

Most of the heavy artillery of the Russian army is usually placed in the artillery rooms, which are almost half-buried and underground. It is connected to the semi-open-air gun pit with guide rails, through which these guns will be towed to the gun pit and then fight in wartime, and the whole process will take about fifteen minutes. And now, just as a squad of Russian soldiers laboriously pulled heavy artillery into position. They suddenly felt a thud in the entire gun room! A large, dark red object then exits from the top. And then smashed directly on the guide rail in front of the passage!

"I felt like an earthquake and I and a couple of people were knocked to the ground. At the same time as I fell to the ground, I vaguely saw a large pile of rubble and broken iron flying out in front of me, and I subconsciously rolled and hid behind the cannon, and then the sound of knocking came from the cannon like a torrential rain. A large hole was drilled into the reinforced concrete dome above the passage in front of us. Thank God, this shell is a dud! However, even so, the entire passage was destroyed. The artillery can't reach the battle position, and my battle is over before it even begins! A Russian artilleryman recalled.

Not all Russian gunners were so lucky, though. There is always one person who will be very tragic, no, an 8-inch cannon has just been moved to the gun position, and the bracket has been put in place and is aiming, and the bomb delivery cart behind has also brought a shell from the ammunition depot to the gun position, and at the urging and threat of the officer, the Russian gunner has just sent a shell to the gun latch. A 12-inch shell smashed into the concrete cover at the back of the gun emplacement without warning, and the powerful impact force directly removed half of the concrete cover from above, and then the shell continued to move forward and landed on the propellant carrier below! With an earth-shattering loud bang, a fire dragon quickly spread towards the gun emplacements and ammunition warehouses. The small and confined air force was simply unable to release the powerful energy, and the high-temperature and high-pressure gases and heat generated continued to explode in the entire transmission channel, and sections of semi-buried bunkers collapsed in the sound of explosions one after another.

Although the dragon eventually leading to the ammunition depot was blocked by a thick fire door, the flames and shockwaves leading to the gun emplacements could not be stopped. , a violent torrent of flames instantly filled the entire cannon pool, and a moment later the entire gun pool turned into a burning sea of fire. Scenes like this are repeated on the battlefield. Not only did the calibrated Russian battery suffer a fatal blow, but even some nearby buildings were affected by the fish pond, a shell fell on the top of a fortress, and the hardened armor-piercing projectile drilled into it like cutting butter, and then under the action of the fuse, nearly ten kilograms of explosives tore the projectile body, and there was a fire storm without dead ends in the entire bunker, and the Russian army of a company in the entire fortress was instantly gone!

The Russian army is not without counterattacks, but under the continuous saturation shelling, whether it is a semi-enclosed artillery nest or an open-air artillery pit, it is almost covered by a rain of bullets, and the power of the 12-inch heavy artillery is almost guaranteed to destroy everything it touches. The artillery nest that the Russians painstakingly built is extremely vulnerable under the attack of special armor-piercing shells, even if the individual artillery nests are relatively balanced and not destroyed, but it does not mean that the servo facilities of the artillery can also withstand such a blow, a 10-inch heavy howitzer found that its bomb delivery channel was hit after firing less than 4 shells, and the collapse of several meters completely cut off the source of ammunition, although the artillery was not destroyed, but at this time it was absolutely impossible to fire a shell!

In this way, the train artillery unit of the Chinese Army slowly cleaned the heavy artillery positions of the Russian army under the guidance of the airship, and 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, and this preparation process lasted for a whole day. And when night fell, the artillery fire of the Chinese army finally stopped. Only a few artillery pieces remained to carry out harassing fire at night.

"How's the preparation?" In an underground bunker, Nie Shicheng asked. "It should be almost, if nothing else, the Russians will be mobilizing a large number of manpower to the southeast this evening to reinforce the damaged offensive. Elsewhere there should be a relative reduction in personnel. And our jamming shelling will last all 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, and this statement is absolutely true, regardless of whether this fortress is real or virtual! After carefully studying the topography and geology of the Nebuchu fortress group, the Chinese army found that the northeast corner of the Nebuchu fortress group was a swamp, and this area was said to be very unfavorable for attack, so the Russians placed ammunition depots and power stations and other key facilities here. And in order to prevent long-range heavy artillery attacks, the ammunition depot is placed about 3 meters below the soil layer, and in addition to the 3 meters of soil, there is a 2-meter concrete dome underneath. The power station, although not so well protected, is very hidden.

However, parts of the swamp are more suitable for excavation in the underground. Originally, the Huaxia Army also gave up on this area, after all, even if the heavy artillery was used to knock open the opponent's cement box, but the troops could not trek in the swamp, and on the surface, there were no offensive facilities such as heavy artillery positions in these places, so at the beginning, this was just an auxiliary offensive direction, and the original plan was to dig a tunnel and then secretly enter the opponent's position to make trouble.

But when the sappers 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 expectations at the beginning. From the first cannon nest to the later underground cave, all the way to the large-scale underground facilities at the back. Nie Shicheng and the others didn't understand what it was after they got to the end!

Until one day, when the Chinese Army and the other side started an artillery battle, the airship in charge of reconnaissance from the air undoubtedly saw that there were many people and vehicles entering and leaving the northeast direction. And the entrances are very secluded and narrow. When this information was sent to Nie Shicheng's table, Nie Shicheng's first reaction was that this should be an important material warehouse for the Russian army, and it may even be an ammunition depot! As soon as he thought of this, Nie Shicheng's heart couldn't help but beat wildly!

If this ammunition depot can be eliminated, the entire attack process will be shortened. But obviously, in this position, because of the topography, it was not used as an offensive direction at the beginning, so the railway was not paved, and the train guns naturally could not pass. Relying on an 8-inch cannon to knock on the opponent's ammunition depot, how impossible is this! As for sending infantry and tanks? Well, that's all there is to think about.

Just when Nie Shicheng was about to give up the plan, the information from the engineering unit made Nie Shicheng overjoyed, he really didn't expect that because of his harassment plan, the engineer unit had dug the tunnel near the opponent's underground fortifications. But think about it, as early as the beginning of the war, the Huaxia Army began to dig when it was defending its rear against the harassment of the Russian cavalry, and it has been digging for several months now. A total of less than 3KM in a straight line distance has already dug under the opponent's wall.

However, this is also because Nie Shicheng doesn't know much about earthwork, and this tunnel is not straight. In order to prevent collapse and underground water seepage, the direction of this tunnel is tortuous and tortuous. Although it was quite difficult to walk along the way, but finally reached the bottom of the opponent's large underground fortifications, looking at the thick foundation in front of him 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 what to do, but I just hope that it will not be a worthless commodity like an underground barracks.
