On this side, in the Japanese headquarters, which was quite safe, Mitsui Takanomiya sent Yamaguchi Jiro away with pity. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 On the other side, Zhang Jianjun looked at his powerful artillery from inside the artillery team, insulting the Japanese defenders in Pyongyang.

On a railway that has just been built, in the middle of the huge two carriages, on top of the huge artillery shock-absorbing structure, is a 300 mm caliber train gun of the Ming Empire with its own barrel raised.

The Ming Empire probably had the most train guns in the world, and had the most powerful 810 mm caliber giant heavy artillery in human history.

The giant train cannon was also mounted on the train, and on several parallel rails at the same time - obviously, the width of one rail was not enough.

The 300 mm caliber train gun is the most equipped in the Ming Empire, and it is also a heavy support gun with relatively balanced performance.

The gun has a long range and a tolerable rate of fire. Compared with the one-sided pursuit of caliber, similar to the show-off of large-caliber artillery, it obviously considers more combat performance.

If undisturbed and operated by skilled soldiers, this equally large gun can attack its target with a rate of fire of about four minutes.

Relatively speaking, this rate of fire is already very terrifying, and it is precisely because of such a fast rate of fire that this kind of artillery is more favored by commanders than larger caliber support guns.

It was even more than the 600 or larger caliber guns that actually delivered the shells, and because of this, it became the standard artillery that the Ming Empire equipped for the group army.

Cranes are hoisting shells onto the train behind the 300 mm caliber train gun, where there is a special ammunition rack for storing shells.

And the shells on this ammunition rack have just been pushed into the chamber of this cannon by a semi-automatic "loader".

The artillerymen on both sides had closed the bolts by this time, and let the guns slowly lift towards the firing angle that had been fixed just now.

After all, it is a bombardment of a target more than twenty kilometers away, so there is no need to aim at all, they just need to slightly correct their firing parameters according to the data provided by the artillery correction observation post, and it will be fine.

"35 degrees 33 minutes! Stop adjusting! Observing the firing angle scale next to the gun, the officer in charge of the firing angle shouted loudly to his commander.

The cannon was fixed at this corrected firing angle, and then everyone had already covered their ears with special headphones.

Even so, there is cotton stuffed in the earphones and eyes to ensure that your ears are not crippled by the roaring cannon when you fire.

Of course, more soldiers had to stay away before firing, covering their ears with their hands in the distance, squinting at the scene of the cannon firing.

"Boom!" A huge explosion began in the chamber of the cannon, and then a dazzling flame erupted from the muzzle of the cannon. The flames had a vague smell of obscuring the sky, and the billowing smoke carried the wind on the faces of everyone around them.

The shells in the barrel had already been fired out at this time, and they flew beyond the speed of sound to targets in Pyongyang in the distance. With a sound piercing the air, the shell would soon fall from the sky near the target.

Then, over the enemy's position, a huge black mushroom cloud rises. This black cloud tumbles upwards and takes away all the life around it.

With the naked eye, it can be seen that this huge explosion was not created by a 150 mm gun, or a shell fired from a 200 mm gun.

Then, when the billowing smoke was already high and high, the sound of the explosion spread through the air, mixing with the sound of other large and small shells exploding.

The air was filled with the foul smell of gunpowder, which made it uncomfortable to breathe. Zhang Jianjun watched these shells roll over the enemy's position like a curtain wall, without a trace of expression on his face.

His troops were already slower than the neighboring 2nd Army, which already made him unhappy, not to mention that in front of him was such a huge city.

Compared with galloping in the wilderness, Zhang Jianjun was very averse to attacking the opponent's heavily fortified cities. The results of such offensive operations are small, but often they are very costly.

But war is war, and it is not up to him to like it or not. He was a military man, and according to the combat mission, he could only carry out the order to attack Pyongyang and capture it by all means.

"When will the shelling end." Without taking his eyes off the artillery mirror, Zhang Jianjun asked the chief of staff beside him, "When will the infantry attack begin?" ”

"Before the shelling stops, the forward units of the 2 infantry divisions will start attacking." The chief of staff replied that he remembered the contents of the battle plan very well, and that this was also part of his job.

Then he continued: "Then the artillery will extend the fire, and the infantry will advance with the artillery fire, clearing the Japanese defenders on the perimeter. ”

Hearing his chief of staff say this, Zhang Jianjun removed his eyes from the artillery mirror: "Let the artillerymen continue to bombard!" Block the opponent's reinforcements! I'm going to drive two wedges in the city of Pyongyang first! ”

The battle is nothing more than several methods, one is to advance from the periphery layer by layer to the middle; Another option is to strike from one direction and then sweep the nearby area one by one.

Each of the two methods has its own advantages and disadvantages, and in the process of making trade-offs, it depends entirely on the situation faced by the commander at the time, as well as his own preferences and choices.

Zhang Jianjun chose this because he wanted to end the battle of Pyongyang more quickly and continue to move south to occupy the southern part of Korea. After all, there was still a 2nd Army competing with him for speed, which made him have to think about the efficiency of the offensive.

In addition, even if it was to attack from the periphery of Pyongyang to the center layer by layer, it would not be able to give full play to the superiority of the Ming Empire's weaponry -- that was a kind of siege warfare in the past, and Zhang Jianjun believed that it was already an outdated choice.

Of course, if it is not for the sake of hurry, the method of attacking layer by layer can effectively reduce losses, and more or less can make the grassroots troops die fewer soldiers.

It's a pity that neither of them is Yang Zizhen or Zhang Jianjun, neither of them is the kind of commander who pities his soldiers. They paid more attention to the overall outcome of the war, which was also inherited from Wang Jue, who is still commanding the battle on the southeast peninsula.

And Wang Jue, at this time, was also ignoring the losses and assaulting the center of Rong......
