The shelling lasted only two minutes and was stopped by the corps captain.

The retreating national rescue army is becoming more and more dispersed. At the beginning, one can hit a target with two or three shells, but now one of the ten shells may not necessarily hit a target with one, which is not cost-effective.

Although I brought a lot of shells, I couldn't waste it endlessly...

The corps leader was very anxious and rushed over after confirming that there was no danger on the battlefield.

He had too many questions to solve.

On the front battlefield, the three infantry squadrons under their command used bayonets to fight against the Chinese army without any of them. Today, there were only three companies of the National Salvation Army. Not only did the subordinates not kill them with bayonets, they were also killed by them in turn. This result was too subverted his understanding of the Chinese army.

He must figure out the reason why the military rescued the country used a bayonet to kill his three squadrons, otherwise he would suffer a big loss in the subsequent attack.

Before he could reach the battlefield, a strong smell of blood came to his face.

The battlefield was even more tragic than what they saw in the telescope.

More than 80% of the soldiers who fell to the ground were their own subordinates, and they rarely saw soldiers from the National Savior Army.

Although they were wearing military uniforms, they could still be seen at a glance through the epaulette.

"This...how is this possible?"

Major Kato looked at the corpse in front of him in a daze, almost unable to believe his eyes, and shouted in disbelief: "Sir, how did the National Salvation Army do it? Is our three infantry squadrons killed by just paying this little loss?"

The corps captain's face became heavier and heavier. He did not respond immediately and went directly to the battlefield to check the corpse at his feet.

"What's going on with these wounds?" The corps leader asked, staring at the bloody holes on the body that were shotgun pellets.

Although the projectile shot out by the shotgun is very small and its caliber is not as large as the bullet used in the 38-large cover, it is a round bead, not a pointed bullet, and its flight speed is much slower than that of the bullet, resulting in a much lower penetration of the projectile. After hitting the body, the skin is broken and flesh is blooming, which looks quite bloody.

"It was definitely not fired from the crawler gun bullet!" Major Kato frowned and analyzed.

This kind of wound is so common, almost every corpse is there, and there are five or six of the same wounds distributed on some corpses. The entire corpse is beaten out of shape, and blood is everywhere!

The captain of the corps was not happy and scolded: "Of course I know this was not fired from the crawler bullet."

"Call the military doctors to check these wounds immediately. I think the reason why we were defeated in the battle with bayonets just now is because of these wounds!"

When the military doctor rushed over, the corps leader inspected dozens of corpses nearby, without exception, each of which had such strange wounds on it.

The corps captain became more and more sure of his judgment and immediately ordered the military doctor: "Check what weapon these wounds are caused by!"

"Hayi!" The military doctor quickly received the order!

After checking three bodies in a row, I stopped and took the deformation projectiles that had just been dug out of the wound: "Captain, the wounds were all caused by these projectiles. They were round before, but after hitting the target, they became what they are now."

"Judged from the depth of the wound, the speed of these ammunitions is not fast, and the effective range is only fifty or sixty meters. If you remember correctly, you should have encountered wounded people with such wounds before."

"What weapon is it?" Hearing the military doctor say that he had encountered wounded people who were also injured before, the corps captain felt that his inner doubts were about to be solved, so he asked quickly.

The military doctor thought for a while and replied: "It seems that he was beaten by a kind of local cannon. It has existed in China for hundreds of years. First, fill the gunpowder in the barrel, and then fill the projectiles. After ignition, the burning gunpowder pushes the projectiles out of the barrel to kill the opponent."

Major Oda immediately responded: "Captain of the regiment, I have seen these kinds of earth cannons. Some earth cannons are made of hollowed out with tree trunks, while others are made of copper and iron."

"The earth cannon made of tree trunks is very small and has a short range, but it is very light in weight. The earth cannon cast by iron and copper has great power. If it fires a shotgun, the maximum range can be 100 meters. However, this earth cannon is very heavy, one or two hundred kilograms light, and four or five hundred kilograms."

"But they have one common disadvantage, the charge is very complicated, and it would be nice to have a shot once a minute."

"There is another disadvantage. The shooting methods of this earth cannon are particularly primitive. It is necessary to ignite the gunpowder in the cannon chamber by igniting the lead wire. It must be used on sunny days, and it also takes time to prepare in advance. If it is rainy, no matter how powerful the enemy is, it cannot ignite the lead wire and launch projectiles."

The captain of the regiment had a rough judgment in his mind and continued to ask: "Is the sound of the earth cannon firing similar to the grenade explosion?"

Major Oda nodded immediately: "The earth cannon made of tree trunks has a small amount of charge, and the sound of firing is similar to the sound of grenade explosions. The earth cannon cast by iron and copper has a large amount of charge, and the sound of firing is similar to the sound of firing is similar to the sound of firing is from mountain cannons!"

Hearing this, the corps leader became more convinced of his judgment: "The National Salvation Army, who had just fought with us for bayonets, must have used wood earth cannons. Compared with iron earth cannons, it is lighter and more suitable for shooting during sports."

"As for the range that is too close, I don't think it's a problem."

"The two armies fought together. As long as the projectiles fired by the earth cannon can have an effective range of 30 meters, it can kill and injure our soldiers in large quantities. A local cannon loads dozens of projectiles, and one shot can kill and injure a large number of soldiers. Then the rifleman rushed up to fight with our wounded and stabbed the wounded to death!"

Major Kato agreed with the analysis of the wing captain, but when he thought that the more than 500 corpses under his feet were all from the Kato brigade, the heartache expression on his face unconsciously appeared, and then he shouted: "Captain, no tactics and tactics can be foolproof. There must be a way to make the earth cannons equipped by the National Savior Army lose their effect in the sting. At that time, we can use the bayonet to kill them in turn. Sir, you must avenge the warriors who died at our feet!"

The captain of the regiment immediately agreed: "Don't worry, I will definitely avenge this revenge. As for the weakness of the earth cannon, Oda Jun had just said that it was very afraid of water and the speed of loading ammunition was very slow."

"As long as these two shortcomings are used well, it will definitely cause a heavy blow to the national rescue army!"

Major Oda immediately expressed his thoughts: "Sir, we can fight bayonets with the National Salvation Army on rainy days to make the earth cannons they equipped lose their function."

"When you fight for bayonets, you can send a few troops to rush forward and force the National Rescue Army to fire out the loaded projectiles from the earth cannons. When they reloaded gunpowder and projectiles, they rushed over and strangled them together, and used grenades to blow off the earth cannons. The National Rescue Army could only fight with us to decide the outcome!"

When the corps leader and two subordinates discussed how to deal with the local artillery, the fourth battalion's troops had already merged in two kilometers.

Every time an infantry squad came into the forest, Chen Zhong, the battalion commander of the Fourth Battalion, would run over to confirm their casualties and results.

After the last infantry squad returned to Jian, the heavy expression on Chen Zhong's face was wiped out, showing a smile from the bottom of his heart. Seeing Zhou Chengru, he looked admiring and sighed: "Captain, the shotgun you made is too powerful."

"Three soldiers killed more than 500 Japanese devils in the three companies, and they were killed with the bayonet that we were the worst at. If they hadn't seen it with their own eyes, I wouldn't believe it."

"Comrades all say that shotguns are easy to use. They kill and injure four or five Japanese devils with one shot. The rifleman just needs to follow behind to gain the results. It's really amazing. Next time I fight with Japanese devils, I will definitely go to the battlefield to see it myself!"
