When the 1st Battalion of the 422nd Infantry Regiment of the 91st Infantry Division stormed the Japanese bunker group in the western section, a brutal fortress attack also broke out on both sides of the Polonai River ten kilometers away to the east.
The Polonai River is called the Horonai River in Japan. It is the main river in the central part of Sakhalin Island. It flows southward into Terpeniya Bay with a total length of more than 320 kilometers. The Japanese army has a fortress on each side of the Polonai River.
As the support for the entire 5° defense line, its strength is not comparable to that of ordinary bunker groups.
When formulating the battle plan, the staff department of the Anton Military Region had fully considered the difficulty of the battle and judged that these two fortresses and the auxiliary fortifications on the side could not be solved by ordinary tanks and guns.
The 93rd Division dispatched two additional self-propelled artillery battalions. The main weapons are fifty-four 15mm self-propelled artillery and eight "Assault Tigers" based on the "Tiger" tank chassis.
The "Assault Tiger" has a total weight of 6 tons and a total length of 625 meters. It is half a meter shorter than Anjiajun's Tiger tank and almost two meters shorter than the German Tiger I tank. The vehicle is 25 meters high.
Half a meter taller than a Tiger tank, and
The German Tiger I tank is about the same height, and its body looks boxy. Its biggest feature is that it is equipped with a 3-mortar gun. The length of the mortar gun barrel is 65 times the caliber. The gun barrel is divided into two layers, the inner and outer layers, and the ablative weight can be replaced.
The inner barrel of the gun.
This 3mm mortar is essentially a breech-loaded rocket launcher, that is, the objects it shoots are rockets, but it can be fired at an elevation angle like a mortar to increase the range, or to shoot at higher altitudes.
The rocket body is 15 meters long. The warhead is 125 kilograms of high explosives or shaped charges. If the target is to strengthen a stronghold or fortress, the 3 mm shaped charge warhead can penetrate deeply into three meters of reinforced concrete. Use
The high-explosive warhead has a range of up to meters and the total weight of the projectile is 35 kilograms.
The propellant during firing will push the projectile out of the barrel at a speed of 5 meters per second. After the 4 kilograms of fuel in the projectile itself is ignited, the projectile will be pushed to the target at a speed of 3 meters per second.
In addition, the front end of the muzzle has a special appearance, which is a ring of exhaust holes, making the barrel look like a pepper shaker on the dining table. The reason for the design of this circle of exhaust holes is that high pressure will be generated when the rocket is fired.
And the poisonous exhaust gas, if the gun bolt is opened decisively after shooting, will only cause a tragic end for all officers and soldiers in the vehicle. Moreover, the waste gas during shooting will cause excessive chamber pressure and cause damage to the weapon itself, so the exhaust hole
The design is to achieve the effects of excreting poisonous gas and reducing chamber pressure.
Of course, the caliber of the weapon is large, and the power is enough to make people excited. However, the officers and soldiers responsible for the operation are suffering - the huge and heavy missile body can only allow the "Assault Tiger" to bring its own fourteen rockets to the battlefield, and one is already behind.
One is lying in the chamber ready to go on the road, the other is on the ammunition carrier plate ready to take over, and the remaining twelve are all on the ammunition rack at the back.
There is a small boom at the back of the vehicle body, which is used to hoist each rocket, which weighs almost five people. It passes through the bomb feeding hatch and is placed on the bomb carrier plate, and then prepared to enter the breech. Do this
When it comes to work, it’s not like someone can just smoke and cool off next to you. It’s about five team members having to complete it together.
The ammunition load is low, so it must be followed by an ammunition truck. This ammunition truck is also modified from a Tiger tank and can usually carry fifty rockets.
There is also a 9 mm caliber close-range defense weapon behind the boom. It is not so much a defense weapon as it is a "large revolver that is fixed and shoots into the sky but has no barrel." It has a turntable ammunition
The cabin is in the vehicle combat room. Smoke grenades can be placed in each bomb cabin to create a smoke screen for air defense cover, or tracer bombs can be installed to shoot attacks, indicate positions or call for help and other signals.
If the enemy infantry swarms around the "Assault Tiger" like ants, the crew can shoot the high-explosive grenade in the bomb bay from the vehicle. The high-explosive grenade will fly into the sky and explode at a height of about two stories, scattering
Many fragments killed the infantry surrounding the vehicle. The right front of the vehicle is also equipped with a 762mm general-purpose machine gun for soft targets, with an ammunition load of 1.
Back to the main story, the two Japanese fortresses were built on high ground of 20 to 30 meters on the east and west banks of the Polonais River. In winter, the Polonais River was completely frozen, and the river became a smooth road for attack. However, the Japanese fortresses formed a tight cross-fire force.
The leading troops were blocked when they reached two kilometers in front of the defense line. The intensive artillery fire and continuous rain of bullets from the Japanese fortress completely controlled the frontal area.
Due to lack of confidence in the defense of Sakhalin, the artillery equipment deployed by the Japanese artillery here is mainly old-fashioned artillery from the Meiji period. The main force is the Meiji 38-type 75mm, 15mm, 12mm and 15mm field howitzers. Although
These artillery pieces generally have a short range and are not as powerful as new field artillery pieces, but they are cheaper in cost and do not require as much materials to manufacture, so they have always been in the Japanese army.
Areas like the 5° north latitude defense line of Sakhalin Island that had not been taken seriously before were simply unable to allocate new artillery. They could only replenish the number with old artillery. But even so, once a powerful blockade barrage is formed, the power of these artillery will be reduced.
It should not be underestimated. Even the thickly armored Tiger tank will have to lie down once it is hit on the top by a 15mm grenade, let alone ordinary infantry. Therefore, blindly attacking will only increase casualties needlessly.
The self-propelled artillery is evenly deployed on the east and west banks of the Polonai River and is 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 Polonai River rumbled into action and drove into two small woods about three kilometers away from the Japanese fortress.
Begin preparations before shooting.
At this time, the two heavy tank companies at the front with more than 30 "Tiger" tanks were working hard to bombard the fortress, and the second line was with more than 50 self-propelled artillery fire fiercely. The dense rain of bullets completely attracted the Japanese in the fortress.
With so much attention, they didn't realize the crisis was coming.
Dong Yan, who had carefully inspected and studied fortresses such as the east bank of Lake Baikal, Chita, and Suifenhe, understood that to deal with the two fortresses in front of him, without air support, he must use the "Assault Tiger" that performed well in the exercise.
”.
In an actual combat exercise held within the heavy artillery brigade, the "Assault Tiger" fired a shell and collapsed a three-story building. In an experiment to verify the destructive intensity of 3mm rockets against armored targets, six scrapped
Leopard II tanks placed together
As a result, a rocket fell in the center, causing six Leopard II tanks to be blown up. Five of them turned upside down. The one that was directly hit was blown to pieces and almost reduced to parts. This gave Dong Yan
Left a deep impression.
Following Dong Yan's order, eight "Assault Tigers" fired a salvo.
Rockets trailing flame tails fell from the sky. Among the eight rockets, four hit the target respectively. Two of them penetrated from the top of the fortress on the east and west banks of the Polonai River, cutting half a meter thick pieces like tofu.
The ice layer penetrated the two-meter-thick reinforced concrete on the top, and then there was an earth-shattering roar.
There was a violent explosion in the Japanese fortress, followed by continuous explosions. Fire and gunpowder smoke were sprayed from the firing ports of the Japanese artillery and machine guns. It seemed that it was hopeless.
The Japanese army's fortress was boarded by a Japanese aircraft, and the pressure on the Tiger tanks in front dropped sharply. With all their strength, they approached the fortress directly from both sides of the bank and the river. The infantry following the attacking tanks fought hand-to-hand with the remaining Japanese soldiers. I-type automatic rifles were densely packed.
The Anjia officers and soldiers who rushed into the Japanese defensive positions used grenades and flamethrowers to clear tunnels and trenches one by one.
Two hours later, the battle ended. The two Japanese brigades deployed in the Polonai River fortress area were completely wiped out. Soon more than 60 self-propelled artillery tanks drove into the almost ruined fortress. Engineers urgently constructed and repaired it.
Position. The infantry, under the cover of Tiger tanks, continued to rush forward, preparing to circle back to the rear of the Japanese army and attack.
When the 93rd Division stormed the Polonai River Fortress, more than 20 kilometers east of the front line in the Langli Hills under the East Sakhalin Mountains, the Japanese army relied on the high ground of 60 to 70 meters above sea level to rush towards them from the north.
The officers and soldiers of the 92nd Infantry Division opened fire violently.
The Japanese army's bunker group was built on high ground and had a commanding position. However, the Anjia army's artillery group was at a disadvantage on the terrain and had no air guidance to confirm the location of the Japanese firepower points. It posed little threat to the Japanese fortress.
The heavy artillery brigade directly under the group army, which is the main force in the frontline attack, consists of five self-propelled artillery battalions, three self-propelled rocket battalions equipped with 13mm nineteen-barreled rocket launchers, and two self-propelled anti-aircraft artillery battalions.
Among them, the self-propelled artillery battalion has some "special" weapons. In addition to the "Assault Tiger" introduced earlier, there is also the "African Lion" self-propelled heavy artillery.
The "African Lion" self-propelled heavy artillery adopts the Tiger tank chassis. The 21mm RER1 heavy mortar gun built by the Taiyuan Military Factory, which has obtained the German patent authorization, is used as the main gun. The gun has a maximum fire rate of 3/hour, a burst of 565 meters/second, and a maximum range of 167
The meter is a German army-level combat unit with extremely excellent performance, especially when attacking solid fortresses and fortresses. The effect is most obvious. It is a good helper for the German army in attacking fortifications and sieges.
In addition to four "Assault Tigers", the two self-propelled artillery battalions assigned to this line are also equipped with four "African Lion" self-propelled heavy artillery. However, they suffer from the inability to accurately locate their targets and are afraid of exposing their targets to artillery fire from the Japanese fortress.
The suppression of the group caused unnecessary losses, so I have been holding back.
In this case, Lieutenant General Dong Jinming, the commander of the 31st Group Army, who received the urgent report from the front, and the V-type general helicopter Hecong Lu, Rui Mei, Pa Bi, Zhang Sha, Jun Jiao, went to Lange.
In the battlefield, direct the ground artillery to attack, trying to knock out the Japanese fortress group before the enemy can react.
"Political Commissar, the superiors sent two helicopters."
The correspondent handed the walkie-talkie to Colonel Tang Tianxu, the political commissar of the heavy artillery brigade. In order to better cooperate with the operations, the battalions of the heavy artillery brigade were assigned to each division. The military and political officers of the brigade headquarters personally visited the front line to command the battle. Tang Tianxu was assigned to
It happens to be the Langley Front.
Tang Tianxu happily put on his earphones, and he put on his earphones and started to blink.
"Ah!? Brigadier Luo, why are you here in person? The wind and snow are so strong, it's dangerous!" Tang Tianxu was stunned for a moment.
"Precisely because the climate conditions are complicated and flight accidents are very easy to occur, I don't trust leaving the task to others! Don't worry, I have experience flying in blizzard weather!" explained Colonel Luo Qing, commander of the 6th Aviation Brigade.
"Okay, please pay attention to safety!" Tang Tianxu warned, and then got to the point: "Now please give us the direction. We will launch the bombardment in three minutes. Please calibrate the shooting elements for us."
"no problem!"
During the conversation, two general-purpose helicopters passed over the artillery position and flew toward the high ground where the Japanese troops were located in the strong airflow.
Three minutes passed in a blink of an eye. As Tang Tianxu's order was issued, the main gun muzzle of one of the four "African Lions" spit out a stream of flames. Soldiers a hundred meters away from the self-propelled artillery felt the 21mm fire.
The powerful shock wave produced when a caliber artillery shell is fired, and the huge sound can be heard two to three kilometers away.
Based on previous aerial maps and the results of on-the-spot reconnaissance by special forces, Tang Tianxu determined the distance to the Japanese fortress.
Sincerely pay homage to the widow, fat and contemptuous, holding on to the marsh and cheating on the garden, loyal and lingering, forgive me?
The whistling armor-piercing high-explosive ejected from the chamber and flew high into the sky. When it reached the highest point, it fell with inertia. The speed became faster and faster, approaching the target at a far-sounding speed.
Luo Qing, who was flying a helicopter, heard the loud noise when the main gun of the "African Lion" was fired below. Is it right?
"boom--"
After more than twenty seconds, the observer saw the exact location of the explosion point through the telescope.

The Japanese fortress group has a solid structure. The walls directly in front of the four forts are all three meters thick. The top one and a half meters of reinforced concrete plus a one meter deep mixture of soil, ice and snow form a thick fortification roof.
Tenaciously withstood the beginning of the attack and
Subsequently, several waves of overwhelming shelling followed. Even the 15mm cannon and howitzer shells could not penetrate the thick defense of the fortress. This made a brigade of Japanese soldiers stationed here extremely confident, waiting to teach Anjia a lesson for those who dared to attack.
military.
However, now the first large-caliber artillery shell has made the Japanese in the fortress lose their confidence. When they hear the sound of the earth shaking, they all have drums in their hearts: Is the roof above the head reliable?
Soon, Luo Qing and the observer, who were flying in mid-air against the wind and snow, once again saw the continuous explosion of red light below. Amidst the violent noise, a big hole was opened on the top of the Japanese fortress, and then huge holes appeared one after another in the field of vision.
Red and black fireballs and explosions occurred one after another. It seemed that the ammunition in the bunker was ignited and exploded.
"Okay, all seven shells hit the target. The first three penetrated the roof of the Japanese bunker, and the last four shot into the fortress. The Japanese ammunition depot was detonated, and the main fortress has been destroyed!"
Tang Tianxu heard what he wanted to hear most, with a smile on his face, he turned to the messenger and said, "Tell everyone, the target was successfully destroyed!"
Two minutes later, as the ammunition was loaded, four "African Lions" and four "Assault Tigers" opened fire again. This time the target was another bunker three hundred meters south of the main fort. Since the main fort was used as a reference,
The eight giant cannons fired together, omitting the test firing link.
Eight consecutive heavy artillery shells destroyed the Japanese fortress like a torrent.
Following the same pattern, the other two bunkers built by the Japanese army on this high ground were also hit by giant artillery shells and were riddled with holes.
The officers and soldiers of the 92nd Infantry Division, who had been firmly suppressed by the Japanese firepower, rushed to the high ground with shouts. In just two hours, they basically eliminated the Japs scattered throughout the hills and opened up the passage south.
Although the Japanese defense line at 5° north latitude was strong and designed to be interconnected with resistance hubs, making it very difficult to conquer, the Japanese artillery fire was old and seriously insufficient in quantity, and it was unable to suppress the Anjia Army's heavy artillery cluster.
In addition, the Anjia Army's long-range artillery, which had a huge advantage in power and range, entered the battle, causing the Japanese fortress to become a passive target, thus changing the situation of the war.
Under this circumstance, after seven or eight hours of fighting, before dark, the Japanese defense line at the 5° north latitude line was completely broken through, and the battle spread in depth, directly targeting the Japanese towns in the southern part of Sakhalin Island.
