When the 1st Battalion of the 422nd Infantry Regiment of the 91st Infantry Division stormed the Japanese pillbox group in the western section, a brutal fortress attack broke out on both sides of the Polonai River, 10 kilometers to the east. Visit 78 Download TXT .//

The Polonai River, known in Japan as the Horonai River, is the main river in the central part of Sakhalin Island, flowing southward into the Gulf of Terpeniye, with a total length of more than 320 kilometers. The Japanese had a fort on each side of the Polonay River to support the entire 5° defensive line, and the strength was not comparable to that of ordinary pillboxes.

When drawing up the battle plan, the staff department of the Andong Military Region had fully taken into account the difficulty of the operation and judged that these two fortresses and the auxiliary fortifications on the sides could by no means be solved by ordinary tank guns, so the group army specially dispatched two additional self-propelled artillery battalions to the 93rd Division, which was responsible for the offensive on this front, and the main weapons were 54 15-mm self-propelled guns and eight "Assault Tigers" built on the chassis of the "Tiger" tank.

The "Assault Tiger" weighs 6 tons, the hull is 625 meters long, half a meter shorter than the Tiger tank of the Anjia Army, and more than two meters shorter than the Tiger I tank of the Germans, the height of the car is 25 meters, half a meter higher than the Tiger tank, and the height of the German Tiger I tank, the body looks boxy, and its biggest feature is that it is equipped with a 3-mortar gun, the length of the mortar barrel is 65 times the caliber, the barrel is divided into two layers, the inner layer of the ablative barrel can be replaced.

This 3mm mortar is essentially a breech-loading rocket launcher, that is, the object fired is a rocket, but it can be fired at an elevation angle like a mortar to increase the range, or to shoot at a commanding height.

The body of the rocket is up to 15 meters long. The warhead is a 125-kilogram high-explosive or shaped charge. If the goal is to fortify a stronghold or fortress, a 3-mm shaped charge warhead can penetrate deep into reinforced concrete up to three meters thick, with a high-explosive warhead with a range of up to meters, and the total weight of the projectile body is up to 35 kg.

The projectile will push the projectile out of the barrel at a rate of 5 meters per second, ignite the 4 kg of fuel in the projectile itself, and then push the projectile to a degree of 3 meters per second and fly to the target.

In addition, the front end of the muzzle has a special appearance, that is, a ring of exhaust holes, making the barrel look like a pepper pot on the dining table. The reason for the design of this circle of exhaust holes is that the rocket will produce high-pressure and toxic exhaust gases when fired, and if the bolt is resolutely opened after shooting, it will only cause a tragic end for all officers and men of the vehicle. In addition, the discarded poison gas during firing will cause excessive bore pressure, which will also cause damage to the weapon itself, so the design of the vent hole is to achieve the effect of excretion of poison gas and reduce bore pressure.

Of course, the caliber of the weapon is large, and the power is enough to make people's blood boil, but it is only bitter for the officers and men in charge of the operation -- the huge and bulky body of the projectile can only allow the "Assault Tiger" to bring 14 rockets to the battlefield, one has already been lying in the breech and ready to go on the road, the other is on the bomb-carrying plate ready to take over, and the remaining 12 are all on the rear bomb rack.

There is a small boom behind the hull that lifts each rocket, which weighs almost five people. It passes through the feed hatch and is placed on the bomb-carrying plate, which is then prepared to enter the breech. It's not like someone can smoke a cigarette and hang out when you're doing this. Rather, five team members have to work together.

The ammunition load is low, so it is necessary to have an ammunition truck to follow, and this ammunition truck is also converted from a Tiger tank, which can usually carry fifty rockets.

Behind the boom there is also a 9 mm caliber close-range defense weapon, which is not so much a defensive weapon as a "large revolver that is fixed to the sky but has no barrel", it has a turntable bomb bay in the vehicle's fighting compartment, and each bomb bay can be placed with smoke grenades to create a smoke screen for air defense cover, or a tracer bullet to shoot signals such as attack, indicating location or calling for help.

If the enemy infantry swarmed like ants to surround the "Assault Tiger", the crew could shoot a high-explosive grenade from the bomb bay from the vehicle. The high-explosive grenade would soar into the sky, about two stories high, and scatter many fragments to kill and injure the infantry surrounding the vehicle. There was also a configuration of a 762-mm universal machine gun for soft targets in the right front of the hull with a load of 1.

Returning to the book, the two fortresses of the Japanese army were built on a height of twenty or thirty meters on the east and west banks of the Polonai River, and the Polonai River was completely frozen in winter, and the river became a smooth route for attack. However, the Japanese fortress formed a tight cross-fire fire, and the vanguard was blocked when it reached two kilometers in front of the defensive line, and the dense artillery fire and continuous bullet rain from the Japanese fortress completely controlled the frontal area.

Due to the lack of confidence in the defense of Sakhalin. The artillery of the Japanese artillery deployed here is mainly the old artillery of the Meiji period, and the main force is the Meiji 38 type 75 mm, 15 mm, 12 mm and 15 mm field howitzers.

Previously unappreciated areas such as the 5° north latitude defense line of Sakhalin could not be allocated new artillery at all, and could only be filled with old artillery. But even so, once a powerful blockade barrage is formed, the power of these cannons should not be underestimated, even the heavily armored Tiger tank has to lie on its stomach once it is hit by a 15mm grenade, let alone ordinary infantry, so blindly attacking will only increase casualties needlessly.

The self-propelled artillery was evenly distributed on the east and west banks of the Polonai River, under the unified command of Colonel Dong Yan, commander of the heavy artillery brigade directly under the 31st Group Army.

After personally observing the situation of the Japanese fortress, Dong Yan issued a new combat order. Four "Assault Tigers" on each side of the Polonay River rumbled into two small woods about three kilometers from the Japanese fortress, and immediately began preparations for the shooting.

At this moment, more than 30 "Tiger" tanks of the two heavy tank companies in the front were trying to shell the fortress, and more than 50 self-propelled guns were firing fiercely on the second line.

Dong Yan, who had carefully inspected and studied the eastern shore of Lake Belga, Chita, Suifenhe and other fortresses, understood that he could deal with the two fortresses in front of him. In the absence of air support, it is necessary to use the "Assault Tigers" who have performed well in the exercise.

During an actual combat exercise held inside the heavy artillery brigade, the "Assault Tiger" fired a shell and collapsed a small three-story building. In the experiment to verify the intensity of damage of 3mm rockets to armored targets, six scrapped Leopard II tanks were placed together, and as a result, one rocket fell in the center, causing six Leopard II tanks to be blown up, five of which were turned to the sky, and the one that was directly hit was blown apart, almost becoming a part. This left a deep impression on Dong Yan.

With Dong Yan's order, eight "Assault Tigers" fired a salvo.

Rockets trailing their tails fell from the sky, and four of the eight rockets hit their targets, two of which pierced through the top of the fortresses on the east and west banks of the Polonay River, piercing half a meter of ice and two meters of reinforced concrete on top like slicing tofu, followed by an earth-shattering roar.

The Japanese fortress exploded violently, followed by a series of explosions, and fire and smoke erupted from the muzzles of Japanese artillery and machine guns. Seeing that there is no help.

The Japanese fortress was mounted on the Turkish planes, and the pressure on the Tiger tanks in front of them dropped sharply. In a battle in which the infantry following the tank attack and the remaining devil soldiers were engaged in a hand-to-hand battle, the dense firepower of the Type I automatic rifle had an absolute upper hand in the face of the Japanese army's 38 guns, and the officers and men of Anjia, who rushed into the Japanese defensive position, used grenades and flamethrowers to sweep the tunnels and trenches one by one.

Two hours later, the battle ended, and the two Japanese battalions deployed in the fortified area of the Polonay River were completely annihilated, and soon more than 60 self-propelled artillery fighting vehicles drove into the fortress, which was almost in ruins, and the sappers urgently built and repaired their positions. The infantry, under the cover of the Tiger tanks, continued to rush forward, preparing to attack the rear of the Japanese army in a detour.

When the 93rd Division was storming the fortress on the Polonai River, in the Langri Hills under the East Sakhalin Mountain, more than 20 kilometers east of the battle line, the Japanese troops relied on the high ground at an altitude of 60 or 70 meters above sea level and opened heavy fire on the officers and men of the 92nd Infantry Division rushing from the north.

The Japanese pillboxes were built on high ground and were condescending. The An Jiajun artillery group was at a disadvantage in the terrain and there was no air guidance to confirm the location of the Japanese firepower. There was little threat to the Japanese fortress.

The heavy artillery brigade directly under the group army, which is the main force in attacking the fortified positions on the front line, is composed of five self-propelled artillery battalions, three self-propelled rocket artillery battalions equipped with 13-mm 19-barrel rocket launchers, and two self-propelled antiaircraft artillery battalions.

Among them, the self-propelled artillery battalion has some "special" weapons, in addition to the "Assault Tiger" described earlier, there is also the "African Lion" self-propelled heavy artillery.

The "African Lion" self-propelled heavy gun adopts the Tiger tank chassis, and the 21 mm RERR1 heavy mortar gun built by the Taiyuan Military Factory authorized by the German patent is used as the main gun, the maximum fire rate of the gun is 3 / hour, the initial 565 m / s, and the maximum firing range is 167 meters.

In addition to the four "Assault Tigers", the two self-propelled artillery battalions attached to this line were also equipped with four "African Lion" self-propelled heavy guns, but they were unable to accurately locate them, and they were afraid that they would be suppressed by the artillery groups in the Japanese fortress after exposing their targets, resulting in unnecessary losses, so they have been holding back.

Under these circumstances, Lieutenant General Dong Jinming, commander of the 31st Group Army, who had received an urgent report from the front, and a V-type utility helicopter from the suburbs of Zhang Shajun went to the Langri battlefield to direct the ground artillery to attack, and strive to destroy the Japanese fortress group before the enemy could react.

"Commissar, two helicopters were sent by the superiors."

The correspondent handed over the walkie-talkie to Colonel Tang Tianxu, political commissar of the heavy artillery brigade. In order to better cooperate with the operation, the battalions of the heavy artillery brigade were assigned to each division, and the military and political commanders of the brigade headquarters were on the front line to direct the battle.

Tang Tianxu happily put on the headphones, and the stab uncovered the spring, which scarlet scar, Pu Sui class, Yi spade glue hinge, Mei Mu, Yi Qiang, lips holding the shackles, blinking the pro-dragon, releasing the arc!?

"Huh!? Brigadier Luo, why are you here in person? The wind and snow are so big, dangerous! Tang Tianxu was stunned for a moment. What is the real feed?

"It is precisely because of the complex weather conditions that it is very easy to have flight accidents, so I don't feel comfortable handing over the task to others! Rest assured, I have experience flying in blizzards! Senior Colonel Luo Qing, commander of the 6th Aviation Brigade, explained.

"Well, stay safe!" Tang Tianxu admonished, and then cut to the point: "Now please show us the direction, we will carry out the shelling in three minutes, please correct the shooting for us." ”

"No problem!"

During the conversation, two utility helicopters skimmed over the artillery position, in a strong air current. Fly towards the high ground where the Japanese army is located.

Three minutes passed in a moment, and as Tang Tianxu's order was issued, the muzzle of the main gun of one of the four "African Lions" spat out a flame, and the soldiers who were 100 meters away from this self-propelled gun all felt the powerful shock wave generated by the 21 mm caliber shell, and the huge sound could be heard two or three kilometers away.

According to the previous aerial maps, as well as the results of the field reconnaissance of the special forces, Tang Tianxu disturbed the distance of the Japanese fortress and asked Xing Han to pounce on the obituary of Xing Han.

After the whistling armor-piercing high-explosive ejection chamber. Fly high into the air, and when you reach the highest point, you will fall by inertia, and the degree will be faster and faster, and you will approach the target with the degree of a long sound.

Luo Qing, who was piloting the helicopter, heard a loud noise when the main cannon of the "African Lion" was fired below.

"Boom-"

After more than 20 seconds, the observer saw the exact location of the explosion point through the telescope, and now gave the full line: the slang of the rod is more than the head of the dragon.

The Japanese fortress complex was structurally solid, with the walls in front of the four fortresses all up to three meters thick, and the reinforced concrete at the top of one and a half meters thick and a mixture of earth and ice and snow one meter deep formed a thick fortification roof, which stubbornly withstood the overwhelming shelling at the beginning of the attack and the subsequent successive waves of overwhelming shelling. Even shells from 15-mm cannons and howitzers could not penetrate the thick defenses of the fortress. This made the devils of a brigade who were stuck here full of confidence, and they were waiting to teach the An Jiajun who dared to attack a good lesson.

However, now the first large-caliber shell made the devils in the fortress lose their confidence and hear the sound of the earth shaking. The drums beat in my heart: Is the top cover on my head reliable?

Soon, Luo Qing and the observers, who were flying in mid-air against the wind and snow, saw the red light that exploded continuously below, and in the violent sound, a big hole was opened in the top of the Japanese fortress, and then huge red and black fireballs appeared in the field of vision one after another, and the explosions came and went, it seemed that the ammunition in the bunker was ignited and exploded.

"Well, all seven shells hit the target, the first three of which penetrated the roof of the Japanese pillbox, and the last four shot into the fortress, the Japanese ammunition depot was detonated, and the main fort has been destroyed!"

Tang Tianxu heard what he wanted to hear the most, a smile appeared on his face, and he turned his head to the herald and said, "Tell everyone, successfully destroy the target!" ”

Two minutes later, as the ammunition was reloaded, the four "African Lions" and four "Assault Tigers" opened fire again, this time targeting another pillbox 300 meters south of the main fort.

Eight heavy shells in a row destroyed the Japanese fortress like a devastation.

Subsequently, the other two pillboxes built by the Japanese army on this high ground were also hit by giant shells and were blown to pieces.

The officers and men of the 92nd Infantry Division, which had been firmly suppressed by the Japanese firepower, rushed to the high ground with a shout, and in just two hours, they basically cleared out the devils scattered all over the hills and opened up the passage to the south.

Although the Japanese defense line at 5 degrees north latitude was strong and the design of each resistance hub was linked, which was very difficult to overcome, the Japanese artillery was old and seriously insufficient in number to suppress the heavy artillery cluster of the Anjia army.

In addition, the participation of long-range artillery, which had a huge advantage in power and range, caused the Japanese fortress to become a passive target, which changed the tide of the war.

Under these circumstances, after seven or eight hours of fighting, before dark, the Japanese defense line at 5° north latitude was completely broken, and the battle extended in depth to the Japanese towns in the south of Sakhalin.
