Rise from eight hundred.

The air defense barrier mentioned by Tang Dao is naturally a kind of air defense fortification!

However, if the timeline is fast forwarded to one year later, if Rostav can come to visit this mountainous area in China, he will be surprised to find that the three air defense fortresses standing on the top of the three peaks are actually in his own empire. A smaller version of the three anti-aircraft towers that stand in the capital.

In the past, on the night of August 1940, 8, the Imperial Royal Air Force, which never sets, carried out its first air raid on Berlin, which shocked and angered the mustachioed Führer. He immediately ordered the strengthening of Berlin's air defense capabilities and personally drew a sketch of the air defense tower, which he then handed over to his chief architect Speer for implementation.

Speer hired Friedrich Tams, a professor at the Technical University of Berlin, to oversee the design. Tams designed two types of anti-aircraft towers, the G tower (battle tower) and the L tower (control tower).

每座G塔的尺寸大约为70.5米×70.5米×39米，墙壁厚度为3~4米，采用钢筋混凝土建造。每座G塔可容纳8000人，而每座L塔可容纳3000人。

The G tower has four turrets, each of which is equipped with two 128mm anti-aircraft guns, and is equipped with a medium and low-altitude defense system consisting of a 37mm anti-aircraft gun, multiple 20mm machine guns and 12.7mm heavy machine guns.

The L tower maintains contact with the G tower through communication equipment, providing it with information about the enemy aircraft's location, speed, altitude, etc., and assisting the G tower in precise aiming and shooting. Every two air defense towers will work together to form a complete air defense unit.

When Tang Dao was studying at the Army Command College, he saw the professor using models and photoelectric systems to simulate the surging firepower of the German Empire's air defense towers.

In the words of the professor: In an era without missiles, ground-penetrating bombs, and nuclear bombs, this design of architecture and firepower equipment was a nightmare for propeller aircraft.

Therefore, in this time and space, even the Germans who created such a project may not be able to understand how awesome the design of the mustachioed head of state who was half madman and half genius was when he was provoked.

In the Second World War in time and space, the German Empire and the mustached head of state failed. Even Berlin, the capital of the German Empire, was captured, but the Berlin anti-aircraft tower was regarded as the last dignity and symbol of the German Empire.

Because they have never been captured! Just like the Sihang Warehouse during the Songhu Battle!

According to statistics, between 1940 and 1945, the Allied forces conducted 363 air raids on Berlin and dropped approximately 4.5 tons of bombs.

These airstrikes killed approximately 3 people, injured 12 people, and destroyed or damaged 12.5 buildings.

However, during this aerial carnage, Berlin's anti-aircraft towers remained standing. With their powerful firepower and solid structure, they tenaciously resisted the Allied attack.

According to statistics, Berlin's three anti-aircraft towers successfully shot down about 3 Allied aircraft.

其中最著名的一次是在1943年11月22日，当时米国第八航空队对柏林进行了一次规模庞大的空袭，派出了440架B-17轰炸机以及500架P-47和P-38战斗机。

This air raid was called "Operation Schweinfurt II" and was the first daylight air raid by the United States against the German Empire. The American cowboys hoped to inflict huge losses on the German Empire, but they did not expect to encounter the stubborn resistance of Berlin's anti-aircraft towers.

The 128mm anti-aircraft guns and heavy machine guns of the Berlin anti-aircraft tower launched intense firepower on the American aircraft fleet, causing serious damage to the American aircraft fleet.

In this air strike, a total of 60 bombers and 5 fighter jets were shot down, and 138 bombers and 26 fighter jets were damaged. This air raid is considered the most serious air defeat suffered by the Americans in World War II.

The Berlin anti-aircraft tower not only performed well in air combat, but also had powerful ground combat capabilities. It played an important role and had a significant impact in the Battle of Berlin.

Not only can they use anti-aircraft guns and heavy machine guns to deal with Allied aircraft, but they can also use rocket launchers and mortars to deal with the Bear's tanks and infantry. These anti-aircraft towers were like small castles, providing the Germans with the last refuge and place of strong resistance.

1945年4月16日，毛熊军开始了对柏林的总攻。他们相继突破了奥得河和尼斯河防线，并最终将柏林市包围起来。苏军总共派遣了250万人、14200门火炮、2450架飞机和1500辆坦克参与战斗。

Berlin's garrison had only 36 divisions, a total of 76 people, 2200 aircraft and 1500 armored vehicles. These also include a number of semi-military organizations such as the police, the Youth League and the National Commandos. The German Imperial Army was at a clear disadvantage in terms of numbers, equipment, and morale.

However, in this brutal battle, the Berlin anti-aircraft tower played an astonishing role and became the strongest position of the German Imperial Army, causing huge casualties and trouble to the Woolly Bear Army.

In order to capture these reinforced concrete buildings, the Mao Xiong people used a variety of means such as 203mm heavy howitzers, rocket launchers, incendiary bombs and explosive packets. However, even so, they were unable to easily destroy these anti-aircraft towers. Some anti-aircraft towers remained standing even after the war, requiring multiple blasts to dismantle them.

According to data, during the Battle of Berlin, the Berlin Air Defense Tower successfully intercepted 32 Allied aircraft and caused more than 4 casualties to the Bear Army. In comparison, the Berlin Air Defense Tower itself had only 7 deaths and . More officers or soldiers were seriously injured.

Tang Dao spent huge manpower and material resources on the top of the main peak of Zishan Mountain and two other peaks with an altitude of over 400 meters to build three air defense fortresses that were almost five times smaller than the Berlin air defense tower.

Each air defense fortress is square in shape, with a length and width of 20 meters each. Because there is no need to hide civilians, the height of the fortress is slightly shorter, about 8 meters. The hollow interior is mainly a passage, and artillery shells are mostly stored in underground warehouses. The thickness of reinforced concrete is approximately 2.8 meters.

It is not as tall and majestic as the Berlin air defense tower. Compared with it, the squat air defense fortress looks like a dwarf or a Titan carrying a giant axe.

But in terms of actual defense capabilities, the air defense barrier, which is slightly thinner in reinforced concrete but has a significantly reduced height, is not much inferior.

The thickness of this kind of reinforced concrete using high-grade cement has also been tested by the engineering company using a 100-kilogram 'cyclone explosive'. The air wave emitted by the explosive alone cannot destroy this kind of wall, unless there is a 200 mm Cannons above the caliber were aimed at them with armor-piercing shells and fired wildly.

The same four corner towers are equipped with two 40mm anti-aircraft guns in each corner tower. Around the corner towers, on the platform protruding from the building, there are six 6mm machine gun emplacements and eight four-unit 20mm anti-aircraft guns. Machine gun fighting position.

Although the main function of the air defense barrier is for air defense, there is also a shooting hole in the middle of the building. Inside, the 37mm rapid-fire cannon, 70mm infantry cannon and 8 Maxim heavy machine guns, which have been basically eliminated by the Fourth Army Regiment, are installed.

If the 20mm machine gun and 12.7mm heavy machine gun on the air defense barrier platform no longer aim their muzzles at the sky but downwards, the air defense barrier will become a monster that can spray a net of death firepower 600 meters away.

Even the air defense barrier at the top of the mountain can extend its maximum firepower range to 2000 meters by taking advantage of its height advantage.

To put it bluntly, this small number of air defense fortresses, which are completely pirated from the Berlin air defense towers, are the most ferocious firepower on the Zishan defensive position, not the 3000 28-meter howitzers hidden deep in the 150-meter mountain behind the entire defensive position.

These heavy artillery had to sacrifice their range of fire for their own defense and the special terrain factors of the mountainous area, which resulted in many blind spots for the Japanese infantry positions approaching the defense area. Their greatest role was not to attack the Japanese infantry, but to deter the Japanese artillery, making them It simply didn't dare to come within 12 kilometers of Zishan.

For the Japanese army, these super fortifications built on the peak took nearly half a year to be completely completed. The Japanese reconnaissance planes had been flying over from high altitudes to take pictures of the terrain of the Zishan area since October. What they took at that time was just a large construction site. A ruin.

When January entered and the main structure was gradually completed, the 1mm anti-aircraft guns under Cheng Tieshou Air Defense Battalion began to frequently attack Japanese aircraft entering an altitude of 40 meters. The costly high-altitude strikes forced Japanese aircraft to reduce their high-altitude reconnaissance in the Zishan area. , which also caused them to have no idea what kind of fire monster would stand on those three ruins.

A huge group of Japanese aircraft assembled in the sky about 50 kilometers away from Zishan, and entered the battlefield from the direction of Taihang Mountain towards Handan City. It is obvious that the target of the first wave of Japanese aircraft was not to directly face the front-line defensive positions of the infantry, but to try to find them. The artillery, baggage and other troops were hidden in the valley by the four-line regiment.

However, the height of Japanese aircraft is mostly maintained at an altitude of 3500 meters. It is simply impossible to find specific targets from high altitude with the naked eye.

Therefore, the huge Japanese aircraft fleet is more interested in destroying possible targets through carpet bombing with more than 50 tons of explosives carried.

Fortunately, Tang Dao had already prevented the Japanese army from doing this.

Five days before the war started, the prince and the Jinan Administrative Office led by him evacuated the people in the Zishan area. Even some villages were 4 kilometers away from the front line of defense and were included in the evacuation.

About 18 people from 2.5 villages retreated into the Taihang Mountains 15 kilometers away under the organization of administrative staff and militiamen.

"Order all fighter planes to drop bombs! Chinese people, tremble under the artillery fire of the Empire!" Mamo Miyano, who was sitting in a 97 heavy bomber, put down the telescope in his hand and picked up the wireless intercom in front of him with great satisfaction. Issue military orders.

Below the roaring aircraft, it was difficult to see anything else clearly, but the Chinese village was clearly visible. Although this kind of civilian target is not on the tactical list planned by the Army Aviation Corps, as the lieutenant commander of the 1st Flying Wing of the Army Aviation Corps, and as the supreme commander of the bomber group, Miyano Mamoru believes that destroying The Chinese villages should also be an important part of destroying the continuous combat capability of the Mountain Four Lines Regiment.

In this way, the tragic casualties of Chinese civilians can be used to psychologically shock the Chinese, and it can also prevent them from obtaining supplies from the villages.

As for the issue of such a waste of the empire's precious bombs without using them on the effective military targets of the Four Troops, Miyano Mamoru believes that the tactic of selectively searching for targets because of the need to save bombs is pure stupidity. It's fucking stupid. Open the door - so stupid.

What is the greatest advantage of the empire over China is its huge industrial strength, so it should use raindrops of bombs to drown all Chinese who dare to resist.

As long as we take over China's fertile land, we can have anything else. What's the point of a little waste?

This round of bombing did not hit the military targets of the Si Xing Regiment, so what are you afraid of? The worst case scenario would be to go back, hang up the bomb again, and do what we just did all over again.

You must know that Duo Tianjun, the commander of the North China Front, went to the army base camp to approve more than 3 tons of large and small aerial bombs as early as three months ago for today's battle.

As long as there are enough bombs, carpet bombing will always have results.

Of course, Miyano Mamoru, who has the command of a huge fleet of aircraft, is not too complacent. He also keeps in mind the warning that the Chinese have a large number of anti-aircraft guns that can threaten air travel, which are all used by the heroic Army Air Force pilots. Life is discovered.

Therefore, even though the roar of the fleet seemed to tear the entire sky, the Japanese fleet still maintained an altitude of more than 3500 meters.

Countless black spots fell from the belly and wings of the aircraft fleet, and columns of smoke rose from the hills and villages.

In the No. 2 air defense barrier covered with green vines and camouflaged nets of woven leaves, Cheng Tieshou held a telescope and stared intently at the black spots passing towards him in the sky. He seemed to be concerned about the visible smoke columns and smoke in his field of vision. The fire turns a blind eye.

"Battal Commander, the enemy planes are so dense and within the range of my 40mm anti-aircraft cannon. As long as we fire, I am confident that with 10 rapid fire rounds, we can kill five or six of them." Mo Songzi looked at the valley opposite. Pillars of smoke rose into the sky, my cheeks were bulging, and my eyes were a little red.

At the foot of the mountain less than 2 meters away from the No. 1000 air defense barrier, Mo Songzi's company had not yet entered the station before the air defense barrier.

It was a large village with a population of nearly a thousand people. The people there were simple and kind-hearted. Most of them had barely walked out of the mountains. Even the news of the Japanese coming was only known to them after the war broke out long after Handan City fell. of.

They don't even understand why those gray military uniforms must fight against the Japanese, but this does not prevent them from choosing to share the same hatred with the enemy because they are Chinese.

Since you said that the little devil is a robber, then our whole village will do its best to help you.

In order to build air defense fortresses and tunnels, this village of 700 people sent laborers. In addition to children and the elderly with real handicap, almost all men and women were dispatched.

But this time, their home was gone.

The home built with Taihang stones for generations was reduced to ashes by the Japanese bombs.

Mo Songzi could fully imagine how sad the old people who had been carried into the mountains by young people would feel when they returned and saw that the houses left by their ancestors had become a piece of white land.

"Batalion Commander!" Seeing that Cheng Tieshou didn't speak, Mo Songzi's face was filled with anxiety.

The fighter plane is fleeting!

"Shut up!" Cheng Tieshou's face was as steely as he put down his binoculars and looked at his most capable company commander.

"Let's not talk about the military order of the regimental commander. Just follow your promise to shoot down five or six Japanese planes. But look, how many Japanese planes are there in the sky? Are five or six Japanese planes just a scratch? You are special One of Liang's main air defense companies attacked with all its strength and caused some skin trauma to the Japanese. Is there a ball for it?"

Seeing Cheng Tie's temper, Mo Songzi wisely lowered his head and said nothing.

"I know you are thinking about how to explain to the people of all ages in Zhujiashan, otherwise we will be sorry for the trust that the whole village has in us.

But that doesn't matter. You are now a company commander, with hundreds of brothers under your command. If you weren't a squad leader or platoon leader who led dozens of people before, how can you act on your whim? "Cheng Tie first saw that although Mo Songzi lowered his head but his eyes were still stubborn, he knew that his subordinate was feeling sorry for the village that was bombed into ruins, so his tone softened a little.

"The Japanese planes are very vigilant and have always maintained a high altitude. Although our 40mm anti-aircraft guns are within reach, it is easy to alert them. Once they continue to bomb at an altitude of more than 4500 meters, we can only stare and wait to be bombed. .

We have to let them take the initiative to lower their height. Even if they want to run away, we can keep pushing their butts and beating them.

The Japanese have also spent a lot of money this time, dispatching such a huge fleet of aircraft at once. You are not unaware of the personality of the regimental commander. He has set an altitude limit of 3000 meters. That means that it is either not to fight, or to fight, it will be a dog fight. The daily pain penetrated into my bones and I dared not come back again. "

"Batalion Commander, I understand!" Mo Songzi nodded, but there was still regret in his eyes. "It's just that I can't bear to see the little devil posing in such a sexy pose. It's such a shame not to fuck him!"

"Haha! Don't worry, they succeeded in the first wave. With the kid's urinary temperament, they will definitely put on more enchanting poses! By then, your baby will be even more comfortable than before." Cheng Tietshou Hearing Mo Songzi's words, he couldn't help but laugh.

"Then, battalion commander, should you ask the 4th Company to fire several rounds from several gun positions, not to scare the Japanese, but to show that we are working very hard to defend our airspace?" Mo Songzi suddenly suggested.

"That's right, otherwise this would be too unlike the style of our Four Elements Group!" Cheng Tietshou nodded and ordered. "The 4st to 1th gun positions of the 10th company of the air defense battalion, each gun has 10 rounds, show it to Gou Ri, and the other gun positions remain silent!"

防空营下辖4个防空连，每个防空连拥有40毫米高射炮12门，12.7毫米四联装高射机枪12挺，20毫米机关炮8门，1、2、3号防空垒分别进驻3个防空连，在整个紫山区域形成一个边长大约4公里的三角形。

The 40mm anti-aircraft artillery squad and the 4th air defense company that are not stationed in the air defense fortress are distributed in the mountain in the form of gun emplacements, which can be regarded as a supplement to the anti-aircraft firepower of the air defense fortress.

A gun position is basically composed of a 40mm anti-aircraft gun and a quadruple-mounted anti-aircraft machine gun. The quadruple-mounted anti-aircraft machine gun not only provides firepower for low-altitude aircraft, but also has the effect of attacking the ground. In addition, each anti-aircraft gun squad also has a specialized The infantry squad responsible for the defense has sufficient resistance even if a small group of Japanese troops come for a sneak attack.

1到10号炮位那就是10门40毫米高射炮对空炮击，10门炮100发延迟引线的开花榴弹在空中炸出一朵朵弹花。

Caught off guard, three Japanese planes emitted thick smoke from their tails!

"Each squadron will be promoted, and the distance between individual machines will be increased!" Miyano Masuke calmly ordered.

Picking up the telescope and looking at the mountains that were already filled with gunpowder smoke, he felt the vibration of the fuselage caused by the air explosion of the artillery shells. Not only was there no fear in the eyes of the Japanese Army Aviation Lieutenant Colonel, but he was more excited.

According to the crazy density of Chinese artillery fire just now, there will never be more than 3000 artillery pieces that can shoot at an altitude of 12 meters.

This is not much different from the predictions of the Imperial Intelligence Department. This should also be the most powerful anti-air combat level of the Four Lines Regiment.

Compared with the ordinary Chinese army, this is already very strong.

But unfortunately, this strength is not enough to face the Imperial North China Front Army Air Force, which is coming with all its strength!

The Japanese Army Aviation Lieutenant Colonel was now suddenly looking forward to the next round of bombing.

He firmly believed that the brave eagles of the Japanese Empire would definitely find the screaming little hedgehogs hiding in the grass, and then tear apart their flesh and blood with their sharp claws.
