"We're going to show the Vanguard, we have better cannons too." The commander of the Kwantung Army, Kenkichi Ueda, said fiercely.

The Kwantung Army needed the kind of cannon that Miandu Shanhaiguan used to enter the customs.

The vanguard army deployed a large number of heavy artillery and blizzard artillery at Shanhaiguan. Without the support of air power, the only possibility is to fight back with stronger firepower. However, the existence of that kind of huge artillery makes the offensive force that he threatens to suffer a lot of losses. Many large-caliber heavy guns were blown up before they could reach the firing range.

"Let the Navy try it with naval guns!" Someone in the base camp suggested.

The base camp also needs to solve these problems first, before we can talk about attacking together, otherwise the Kwantung Army will be blocked out of Shanhaiguan, what kind of unified command can we talk about? Besides, the giant cannons are not only in Shanhaiguan, at least there are four now. The one in Qingdao beat the King Kong, the one in Xuzhou drove away the 13th Division, and at this time, there was also a place opposite the Yellow River near Zhengzhou, and huge artillery shells fell on Zhengzhou and Jiaozuo from time to time, which also made them feel the kind of fear of the 13th Division, and they did not dare to gather a large number of troops at all.

The huge artillery in these four places needs to be knocked out so that the momentum of the offensive will not be contained. The best way to attack these cannons should be to bombard them from the air, but the sky at this time is in the vanguard. He said that if he wants to occupy the air superiority, he must win by numbers by virtue of his existing aircraft. When the quantity reaches a certain level, it causes a qualitative change. When the ratio exceeds 3 to 1, the advantage of weapon quality will be greatly reduced, and the larger the ratio, the more effective the attack will be, until the final victory will be achieved.

According to his own intelligence observations, the vanguard army can dispatch more than 200 fighters at a time, or even 300, and if he wants to gain air superiority, he needs at least 1,000 fighters, and they are fighters. He said that there are more than 2,000 combat planes of the navy and army, but there are many bombers and other types of planes.

Using tactical arrangements, fewer planes may be needed, but the consumption of these fighters is also unbearable for Yue himself. After fighting the air force of the vanguard army and gaining air supremacy, he said that he did not have many planes to protect the mainland and the opposing Soviet Russia and other potential threats.

He said that the prototype of his new aircraft has been successfully tested and is preparing to be put into production. Such an aircraft can easily shoot down the 96 ship battle, which can neutralize the superiority of the fighters of the vanguard army. It doesn't take a lot, just a hundred such aircraft to partially neutralize the air superiority of the Vanguard, opening a gap in the sky.

In addition to the attack from the air, the advancing attack of the land army, the losses were too great, and the crushing defeat of the 12th Division has already shown the impracticality of this approach. That's why it was proposed that the navy attack.

"No, we have a cannon too!" The Army people refused. They still have a secret weapon that they haven't used.

On the snowy field of the northeast, a train is moving slowly in the direction of Shanhaiguan under the heavy protection of the Kwantung Army. The 12.82-meter-long barrel and complex booming platform on the top already indicate that this is a train gun.

During World War II, he only had one train gun. This train gun was originally intended to defend the Bay of Tonkin with a 240-mm cannon ordered from the French. Because of its 30 years of service, it was named the Type 90 cannon.

After 918, in order to prevent the attack of Soviet Russia, he himself built many fortresses in the northeast and north. The Type 90 cannon produced by the French company Schneider was converted from a shore defense gun to a train gun. This year, the renovation was completed at the Yuli Manufacturing Plant. The reason why the people of the army have this tone is because this train gun has been transported to the northeast. After landing in Dalian, it was transported to Suizhong in a disassembled way before it was assembled.

Originally, this cannon was not transported to the Tiger Head Fortress until 42 years and put into use. In 45 years, when Soviet Russia attacked the Kwantung Army, its whereabouts were unknown. Later generations speculated that it may have been taken away by Soviet Russia, and nearly one million Maozi people in the Northeast kept moving. At this time, there was a vanguard army, and because of the Shanhaiguan cannon, the devil got it in advance.

The news also quickly reached Meng Xiang's ears.

"Train guns?" Meng Xiang still knows a little about it, after all, he only has this one train cannon.

"This kind of artillery has a long range, more than 50 kilometers, and all units should pay attention." Meng Xiang instructed. Although the specific surname of this train gun is unknown, the claimed range of 50 kilometers is impressive. Since the golden finger of history gave Meng Xiang enlightenment, there is nothing wrong with being careful.

He said that his train cannon stopped far away from Shanhaiguan, about 42 kilometers away from Shanhaiguan. The giant cannon of the vanguard army was nearly 5 kilometers behind the Shanhai Pass, which was already more than the distance of the giant cannon attack that he knew, but they still had to be careful.

That's the difference between train guns and fortress guns. Train guns rely on maneuverability, and protection is very fragile. And the fortress cannon has a thick layer of protection on the top. The fact that his plane's bombardment of the giant cannon had no effect shows that its protection is very thick, but the Type 90 train cannon may not be able to withstand the opponent's cannon.

"Please rest assured, the range of this cannon can reach 50,120 meters, far exceeding the giant cannon of the Zhi Na man." Umegawa Dihori said confidently to Shozo Riverside. Kiyotaro Uemura has been suspended, and Shozo Kawabe has taken over as division commander of the 12th Division.

"Their rate of fire is fast!" Kawabe Shozo reminded. He used to be the brigade commander of the garrison brigade that provoked the Lugou Bridge Incident, and he was the one who ordered the shelling of Wanping County. When he was transferred to the 12th Division, he served as the deputy chief of staff of the North China Front and knew the power of the vanguard army's giant artillery.

"No problem, such a long distance can only allow the dust from the shells of the Chinese to fall under our feet." Umegawa Dihori said arrogantly. The ultra-long-range attack of the Type 90 with a 50 km, as far as he knows, there are few Europeans and Americans who can compare, and the Chinese are even worse.

With Umegawa's order, the 2x6 wheeled carriages on the 136-ton train gun began to be unfolded and fixed, and the huge recoil of the train gun required these gun mounts to cushion it.

There are only two giant cannons in the vanguard army, but with such a high rate of fire, he has been speculating that there are still unknowns.

The positions of the two French cannons that had been revealed by the vanguard army had been determined, and the Type 90 train guns directly adjusted the parameters and entered the firing state.

"Fire!" When everything was ready, Umegawa Dihori ordered loudly.

"Boom!" A ball of flame erupted from the muzzle of the barrel held high, and a puff of smoke filled the air. A scream pierced the sky and passed into the distance.

"The distance is far away, although the accuracy deviation is large, but what we need is deterrence." At such a distance, Umegawa Dihori also knew that it would not necessarily hit the spearhead's cannon, but this threat would make the vanguard's cannon dare not attack at will.

The observation balloons in the sky and the reconnaissance planes hovering in the distance were all watching it closely, and even the agents lurking in Qinhuangdao were also watching there.

"Watch out, the Vanguard's cannons are attacking!" The reconnaissance planes in the sky first reported not the attack of the Type 90 train guns, but the flames and smoke from the muzzles of the vanguard cannons.

The screaming in the sky had just passed, and it came again, and it got louder and louder, heading straight for it.

Umegawa Dibori's face couldn't help but change, such a voice was too familiar. The place where the shells landed must have been around them, maybe even above their heads.

"Be careful! Protective shelling! He shouted, but in his heart he cursed, "Bastards, you nasty fellows. The intelligence of the empire was too backward, and the range of the giant cannon of the Chinese people may also exceed 50 kilometers. ”

"Boom!" With a loud bang, the ground shook, almost causing Umegawa Dihori on the podium to fall. The creaking sound of the shaking train was frightening, the smoke and dust dispersed, and a huge pit appeared more than a hundred meters away from the front of the train, and the bloody corpses of a dozen devils were scattered around.

"Ahead to the left, about 230 meters away." The reconnaissance plane in the sky began to report on the battle of the train guns.

At this time, Umegawa Dihori no longer knew this, what he needed was to make the train cannon a little safer. If the shell had been any closer, I'm afraid the train cannon would have been over.

"Put away the gun carriage! Retreat 3 km! Umegawa Dihori ordered anxiously and loudly.

"Boom!" It didn't take long for another loud bang to explode around him, and several devils who were guarding there disappeared directly in the roar, leaving not even a strip of cloth. Umegawa Dibori experienced the high rate of fire of the Vanguard Cannon, but this was the result of the Giant Cannon's reduced rate of fire in order to improve its accuracy.

"Boom!" When the gun carriage of the train gun was about to be retracted, the third huge cannon shell landed not far in front of the front of the train gun. On the edge of the deep pit, the broken rails were twisted into twists and rolled in the air, and the front of the train pulled by the train cannon was blasted out of the tracks and fell to the side.

"Get out of here!" Without waiting for all the gun mounts to be closed, Umegawa Dihori gave the signal to evacuate. Umegawa Dihori secretly congratulated himself that this time the traction train power was arranged front and rear. The front is ruined, but it can still run with the drag of the rear power.

"Boom!" The fourth shell landed where the train cannon had just been waiting, and then blasted a deep crater in the tracks. On the train gun, which had already driven more than 300 meters, Umegawa Dihori wiped a cold sweat. The train cannon is okay against the machine gun and the small-caliber artillery or something, but the only thing with the help of the giant cannon is the ultra-long range. But the range of the cannon of the vanguard army is also perverted and ultra-long.

"After retreating to 50 kilometers, make a last ditch effort."
