Mountain guns are curved guns, infantry guns are direct-fire guns, one can kill fighters in the trenches, and the other can deliver devastating blows to enemy fortifications.

The distribution of artillery fire in the Japanese army was very scientific.

The 20 minutes of wanton bombardment and indiscriminate bombing turned the No. 1 position to the ground, and a neat-looking hill that was originally white was blown black and yellow, completely unrecognizable.

Sun Yongqin, who was watching all this with a telescope on the main peak position, had muscles on his face tightened, how could he not worry? There are nearly 300 of his soldiers on that position! If it weren't for the fact that after receiving Liu Lang's military plan and learning that he was going to command it in person, Cai Dadao and the others would have commanded the soldiers to dig enough anti-artillery holes in various positions, and they might not have seen such fierce artillery fire from the Japanese invaders, just seeing the thousands of Japanese troops, Sun Yongqin would have ordered to abandon this place and retreat into the mountains as before.

Liu Lang's expression beside him was very indifferent, and the fierce artillery fire of the Japanese army had long been expected by him. But if the Japanese invaders wanted to capture the hilltop position with artillery fire and not pay the price, it would be really too much. If they all change to 150 caliber heavy howitzers, maybe it's about the same.

It's a pity, can they get that thing in?

However, Liu Lang's desire to give the Japanese artillery unit a ruthless shot also failed. This infantry wing of the 4th Division had apparently learned the lessons of the 8th Division's artillery unit in the Battle of the Great Wall, with at least two infantry squadrons on either side of the artillery unit building field defensive positions. It's too hard to beat their minds.

Of course, this is also their bullying Sun Yongqin's department for not having artillery or not having enough range of mountain artillery, if the two Bofors mountain guns with a range of up to 9,000 meters in the Zhao Ergou artillery battalion were here, they would definitely teach the Japanese artillerymen who deployed the artillery position at a distance of only 2,500 meters from the front line how to behave.

The infantry squadron in charge of the attack still adopted the old tactics of the Japanese infantry attacking with one infantry squad attacking head-on, and two infantry squadrons going around the flanks to contain and look for the enemy's flaws.

The volunteers, who had fought no less than 10 battles with the Japanese army in the past two years, also knew very well that this was a feint attack by the Japanese army, and once the firing point was exposed, their grenadiers and approaching infantry artillery would focus on the firing point, and then use heavy firepower to suppress the defending infantry and cover their own infantry to charge and occupy the position.

Although the routine is simple, it is very practical, especially against the Chinese army, which lacks heavy firepower, and is often helpless. In the end, he had no choice but to risk the enemy's superior firepower and his counterfire, and the result was naturally heavy casualties.

Sure enough, when the Japanese infantry squad advanced to about 200 meters away from the mountainside position in a skirmish line, with the sound of a horn on the main peak, the light and heavy machine guns deployed by the volunteers on the position began to speak, and the Japanese troops were skillfully prostrate on the ground after being swept down several people in a row, and within a minute, several Japanese grenadiers that were hiding behind natural bunkers such as mountain passes more than 200 meters behind them began to fire wildly, bombarding several fire points that had just opened fire, and several infantry guns that had reached only 800 meters away from the front line also opened fire violently, a posture of not destroying the exposed firepower of the Chinese resistance army.

Regardless of whether it was really destroyed or not, as soon as the artillery of their own side opened fire, the Chinese resistance on the mountainside position was dumbfired, and up to 4 92 heavy machine guns arranged in the rear of the Japanese infantry squad also began to fire, suppressing the defensive positions of the volunteers.

You must know that an infantry brigade of the Japanese army is only two machine gun squads equipped with a total of 8 heavy machine guns, and for this attack, this infantry brigade responsible for the main attack directly took out half of the heavy firepower. Coupled with the 6 light machine guns that this infantry squadron has, the fire of 10 light and heavy machine guns fired fiercely and splashed the soil on the volunteer position, and the shelling that was still ringing out, nearly 300 volunteer soldiers on the position were so beaten that they couldn't lift their heads for a while, let alone shoot back.

Observing this situation, the Japanese soldiers, who had just been prostrate on the ground to avoid the bullets, jumped up and shouted "onboard" and launched a charge under the loud shouts of a Japanese second lieutenant with a saber drawn.

In just ten seconds, they advanced about forty or fifty meters, and a Japanese infantry squadron in the rear as a reserve also began to move, and two more than 100 Japanese troops were pressing towards this side.

Obviously, this is already a feint attack into a real attack, and the Japanese army actually plans to break it in a battle. Liu Lang, who was watching all this from the telescope, couldn't help but show a hint of ridicule at the corner of his mouth. The Fourth Division also took itself too seriously, and really thought that the Japanese Army was the first in the world?

"Commander Liu, do you want to order the brothers in the trenches to fight back, otherwise that team of little devils will rush up." Sun Yongqin put down the binoculars in his hand and looked at Liu Lang with an anxious face.

Before the war, Liu Lang, who took over the command of Sun Yongqin, had already ordered that the command of the No. 1 and No. 2 forward positions should be under his full command, and no one should open fire at will and cause unnecessary casualties.

"Don't worry, there are too few little devils in a team, not enough, wait." Looking at the two infantry squads that were gradually accelerating in the telescope's field of vision, Liu Lang shook his head and said.

"But 。。。。。。" Sun Yongqin wanted to speak again, but seeing that Liu Lang did not continue to explain to him, he could only stomp his feet and helplessly picked up the telescope in his hand again to look at the battlefield in the distance.

If it weren't for Liu Lang's two battles two years ago that left an indelible impression on Sun Yongqin's heart, Sun Yongqin would have to argue loudly no matter what. But Liu Tuanzuo's two battles were too godly, and God made Sun Yongqin transfer the command without hesitation.

In the face of such an offensive by the Japanese army, the supreme commander of the Volunteer Army was so anxious, let alone the soldiers who were still in the trenches.

At this time, perhaps because the distance between the Japanese troops was getting closer and closer, the Japanese infantry artillery had ceased firing, the grenadiers had gradually stopped, and only the light and heavy machine guns of the Japanese army were still suppressing the fire.

The commander of the 3rd Battalion of the 1st Regiment of the Volunteer Army, who was in charge of garrisoning the No. 1 position, was lying in a bunker reinforced with logs and camouflaged with loess, and he was already anxious to watch the small group of Japanese troops gradually approaching the position.

As a front-line commander, he knew very well what the consequences would be if a small group of more than 50 Japanese troops attacked the trenches. That would cause the two infantry squads on the flanks to contain their own firepower also start to charge, and when the more than 100 Japanese troops who were following up behind attacked the position, in the end, the more than 200 brothers under his command could not withdraw if they wanted to, which was much more terrible than a rout.

That was the end of total annihilation.

The Japanese army was only forty or fifty meters away from the position, and the soldiers in the trenches had even seen the big yellow fangs that the Japanese soldiers showed when they opened their mouths and shouted "board load".

"Order the No. 1 position to return fire head-on, except for the heavy machine guns, all light machine guns can fire, pay attention to the grenadiers of the little devils, and the grenades will smash me hard." Liu Lang's military order was also issued at the right time at this time.

Since there was no professional communication unit like the Independent Regiment, at the suggestion of Liu Lang, Sun Yongqin's department cleverly used the length of the trumpet sound to establish its own slightly rudimentary and unique messaging.

Although the sound transmitted is only a few hundred meters, this is enough for a battlefield of this level.

The battalion commander, who received the signal of the command to counterattack, roared angrily: "Throw grenades, open light machine gun fire, and beat the little devil back to Lao Tzu." ”

Due to the lack of enough artillery and the fact that artillery shells were really difficult to transport, grenades were the "heavy weapons" that the Independent Regiment had aided Sun Yongqin's troops the most in the past two years. However, limited to the conditions, the goods were not finished products, most of them were gunpowder, and Sun Yongqin had to find a way to produce the long wooden handle and cast iron bullet shells, and how to make them, Liu Lang specially sent two technicians to Rehe to guide them in production for half a year.

It can be said that in terms of the number of weapons, Sun Yongqin's department now has the most not the millions of bullets left to them by Liu Lang, but the grenades that have been continuously produced for two years. Although the process of making earth-made iron-making is rough, it accidentally caused a very high fragmentation rate, and at the same time, the gunpowder provided by Liu Lang is of good quality, and the power of the home-made long-handled grenade made by the peasant army is very strong, which is not worse than the grenades made by the domestic regular military factories taken by the national army.

By this time, the Japanese had already entered the area 40 meters in front of the position.

It can only be said that Liu Lang's military order to choose to counterattack is too appropriate, this area is the best distance to throw grenades from a high position, and if the Japanese grenade is on the plain, it may be able to throw more than 30 meters, but in this position, you let him go from the bottom up, they can't throw it so far, even if the slope is not very steep.

The more than 100 soldiers on the frontal position did not look at the Japanese troops who had entered the final charge and began to run wildly, and threw out three or four grenades that had already been placed around them in one go.

That's nearly 500 grenades, almost the equivalent of 500 mortar shells.

The frontal defense line, which was no more than 300 meters wide, was almost every four or five meters from the front and back, and a grenade exploded, and the Japanese army's squad of nearly 60 people, which had already begun to fight in the First World War, was considered unlucky.
