Du Kaishan's plan did not go very smoothly at the beginning. When the tunnels began to be dug, the Japanese fortress garrison in the mountain leg really couldn't keep calm anymore. In the mountain leg where there was no Japanese firepower, Even dozens of new fire points suddenly appeared under the mountain roots.
When the tunnel was dug under the root of the mountain, in order to destroy it, some troops were even launched from several hidden tunnels to launch a counterattack, trying to blow up the tunnel that was being dug at a very fast speed. However, they were beaten by the covering troops with light and heavy machine guns and The mortars just blew back up again.
The Japanese troops who counterattacked were bombed back, but the grenades fired from dozens of cross-firing firepower points on the mountain legs and the infantry artillery with extremely awkward shooting angles also caused a lot of casualties to the tunnel digging troops. The Japanese had fought The angle of the incoming grenade was very tricky and accurate, but the retaliatory mortar shells did not even scratch the surface of these fortifications.
The Japanese commanders were very shrewd. They clearly saw the dangers of these tunnels and tried every means to destroy them. When the tunnels were dug under the roots of the mountain, the Japanese army also sent soldiers to carry out suicide attacks by strapping explosives on their bodies as individual soldiers. , trying to blow up the tunnel.
If it weren't for the incendiary bombs fired by the artillery, which ignited the dense bushes on the legs of the mountain, blocking the Japanese army's shooting sight. At the same time, the 37 rapid-fire cannons were pushed directly to the foot of the mountain to carry out point-to-point strikes despite the fire from the Japanese army on the mountain. They destroyed several bunkers with the most intense firepower and the most important positions of the Japanese army. At the same time, the covering troops lost nearly half of their heavy machine guns, suppressing the Japanese counterattack force, and were almost defeated by the Japanese army several times.
Fortunately, the excavation distance of the tunnel was not too far. Although it took a certain amount of casualties, it was finally dug to the foot of the mountain. With the regiment's 37 rapid-fire artillery group, level-firing 75 field artillery, and a large number of rocket launcher operators, they risked heavy casualties. , using close-range shooting to clear out the dozen or so bunker groups exposed on the Japanese army's mountain legs bit by bit, the infantry launched a full-line attack.
After the tunnel excavation was completed, the unlucky ones were the Japanese troops. Along with three red flares, the attacking troops were organized in squads, either pushing gasoline barrels filled with mixed cement, or carrying Molotov cocktails and cluster grenades. , or jumped out of the tunnel and rushed towards the Japanese bunkers, or used the opened gasoline barrels as simple bunkers to rush towards the Japanese bunker group under the cover of firepower.
Du Kaishan assigned the few remaining bunkers at the foot of the mountain to rapid-fire artillery, and the direct-aiming artillery, which drew the infantry's attack line above the legs of the mountain, was out of reach. However, artillery with sufficient ballistic curvature, such as mountain artillery, was not powerful enough. Exploding the bunkers, the lightness and flexibility of the rocket launcher, grenades, cement and flamethrowers were used to attack the bunker group on the entire mountain leg.
Qin Zesheng was still very cautious when formulating his attack plan. He used the portability and randomness of the rocket launcher to first eliminate the covering fire points around the Japanese Yongbei fortifications, and then used the shooting blind spots of the Yongbei fortifications to use a large number of explosive packets, cluster grenades, and incendiary bottles. , and even cement can be used to implement directional blasting or directly use a large amount of cement to block the shooting holes of permanently prepared fortifications for which rocket launchers are powerless unless they directly hit the shooting holes.
Obviously, when the Japanese army was designing and building fortifications, they did not expect that there would be a direct-aimed weapon like a rocket launcher in the world that was light and could be used in almost any terrain. Although the penetrating power of this weapon could not deal with those poured There are permanent fortifications with a thickness of one or two meters of concrete, but it is not a problem to knock out the covering fire points of civil structures around these permanent fortifications.
Although the number of permanent preparations of the Japanese army is large, they do not cover the entire mountain. Except for some permanent preparation firepower points, most of the fortifications are still constructed by civil engineering. However, many of the fortifications are covered with steel plates to strengthen the defense. Although the defense against vertical firepower has been increased, the frontal defense is still compared to those permanent fortifications built of reinforced concrete.
The firepower points on the flanks of these civil structures and the permanent fortifications are interdependent and cover each other. When the Japanese army comes, those permanent fortifications, which are strong and can prevent direct hits from 100mm artillery, serve as support points to protect these civil fortifications. , and the much wider shooting range of these civil fortifications can protect the flanks of those supporting points.
However, the Japanese army probably never thought that their opponents would hit the covering fire points and attack those permanent fortifications that even small-caliber direct-aiming artillery could do nothing about. In addition to forcing incendiary bottles inward, they even directly used The method is to directly block the shooting hole with the mixed concrete.
With the cooperation of this variety of tactics, two-thirds of the Japanese bunkers on the entire mountain were defeated within an hour, and the two permanently prepared fortification groups located on the mountainside served as the defense support for the entire mountain. , then it will either be completely burned inside and out by the opponent's flamethrower, or the shooting hole will simply be blocked by a large amount of cement, thus losing its suppressive effect.
Looking at the subsequent attack that was progressing smoothly, Qin Zesheng put down the telescope in his hand and said to Du Kaishan: "Commander, your skills are exquisite. Although it is the first time to use this kind of tactics, it is somewhat unfamiliar, but the casualties are higher than expected." The ones were much smaller, especially the tactic of using bazookas and flamethrowers to clear the cover fire, and then using cement to directly block the Japanese shooting holes. It was so whimsical that the little Japanese had to be blocked inside now."
"Those thick turtle shells built by the Japanese, we can hardly do anything to them without heavy artillery. It is also very difficult to use explosives alone. One firepower point, one hundred kilograms of explosives have been blown up, and there is basically no major damage. Even if the Japanese troops inside are destroyed Shocked to death, but they can still quickly mobilize troops to support through underground passages, there is no way for us to completely destroy these turtle shells."
"It's different if you can block their shooting holes with cement. Even if the Japs reinforce more troops, without the shooting holes, the Japanese reinforcements will not be able to attack our army. Without the shooting holes, their machine guns will not be able to attack us." No matter how many there are, no matter how strong the fortifications are, it will be of no use."
Hearing Qin Zesheng's praise, Mr. Du Kaishan blushed and said, "I didn't think of this. If I had this ability, I wouldn't have to worry about these turtles. This method was thought of by No. 1. Those cement and gasoline barrels were also specially approved by him from the supplies seized in Dong'an. This attack tactic was drawn up by No. 1 himself, we are just trying it out first."
When Du Kaishan was talking to Qin Zesheng, he did not put down the telescope in his hand, but kept closely observing the battle on the mountain. He was quite satisfied with the fierce battle on the mountainside, but he was not satisfied with the one who attacked the ridge position several times. After breaking into the Japanese artillery fortification, I was very dissatisfied when I was kicked out again.
Without the threat from the side and rear, the leading company, which was suppressed in a depression on the mountain, returned to the sun again. Although they did not carry cement and Molotov cocktails, they specially strengthened two rocket launchers and a large number of grenades, explosive packs, and other equipment before setting off. There is a blasting tube.
Due to the problem of shooting range, the Japanese army does not have many permanent firepower points on the ridge. Most of the permanent firepower points are concentrated on the front of the mountainside. The ridgelines are mostly field fortifications. The biggest threat to the leading company is not The Japanese field fortifications on the ridgeline were inverted firepower points on the mountainside.
The Japanese troops in the field fortifications on the ridge were suppressed by artillery fire. After the inverted firepower points on the sides and rear were eliminated by friendly forces, without the threat on the sides and rear, the leading company naturally fought more easily. However, the Japanese troops deployed on the reverse slope The counterattack was quite powerful.
In particular, after the Japanese troops in other fortifications discovered that the ridgeline was tight, they quickly reinforced several permanent artillery firepower points at the ridgeline on the top of the mountain through underground passages. Not only did they mobilize a large number of firepower for the artillery fortifications in the shortest time, There were few reinforcements, and these reinforcements also cooperated with the Japanese troops on the reverse slope to continuously launch counterattacks against the vanguard troops rushing up the ridge.
The Japanese troops deployed on the reverse slope and quickly reinforced the troops through underground passages to the ridge line, counterattacked with great intensity. The leading company that rushed up succeeded several times and was driven down several times. Although two Japanese troops were blown up with explosives artillery bunker, but its own casualties also reached one-third, and the attack intensity dropped significantly.
Looking at the leading company that was not making good progress, Du Kaishan put down the telescope in his hand and said to Qin Zesheng beside him: "We are moving a company up. So many troops are concentrated on the mountainside. Is it useful? The troops are all concentrated together. The density is too high." "Gao, don't forget, the Japanese army has heavy artillery on the Camel's Peak behind. Once a 150 heavy artillery fire comes down, how many casualties will you have? It's not like the Japanese have never adopted the tactic of sharing the same fate."
Qin Zesheng nodded in agreement, grabbed the walkie-talkie next to him, and directly set up a link to attack the ridgeline for the lead. The follow-up troops followed the predetermined plan and carefully cleared the various Japanese firepower points on the hillside. At the same time, two The company rushed into the mountain along the entrances of several underground passages that had been exposed abandoned by the Japanese army.
The entrances and exits of these hidden tunnels specially used by the Japanese army to launch tactical counterattacks are very cleverly built. According to the Japanese army's plan, each entrance and exit can ensure that all troops of the size of a squadron can rush out of the fortifications within five minutes. Therefore, these entrances and exits are very clever. Although the entrances and exits of the hidden tunnels were cleverly built and heavily covered, and would have been difficult to detect unless the Japanese army took the initiative to attack, the entrance and exit passages were not narrow.
The troops who rushed into the fortifications followed the underground passages built by the Japanese army and launched an attack deep into the Japanese army. The attacking troops used flamethrowers, grenades and submachine guns. They thought that the Japanese army would attack deeply and fiercely. When they saw the troops rushing into the Japanese army, Inside the fortifications, Du Kaishan, who was afraid that the inexperienced troops would suffer losses, immediately threw in the reconnaissance company following him to replace the ordinary company.
