All non-combatants in the fortress hurriedly entered the air-raid shelter.
Including some gunners.
Most of the forts have only a few observation posts outside.
The main purpose was to observe the movements on the river and prevent Japanese warships from entering the blind spot of the fortress's fort under the cover of aircraft.
Once there is such a sign, the artillery fire will definitely be carried out at the risk of aircraft bombing.
War means fighting tooth and nail. Using my life in exchange for yours.
"quick!"
"quick!"
At the same time, all Suloton machine guns and Oerlikon machine guns were dragged out and prepared to fire into the air.
Jiangyin Fortress is a big garbage basket. Everything is put in it. Many machine guns without shells are thrown here for later use.
Originally, these things were too much to take up space, but Zhang Yong came and brought corresponding shells, so they became useful.
"quick!"
"quick!"
Three machine guns are arranged in a group.
Shoot one target at the same time. Directed by a team leader.
Equipped with a telescope.
Equipped with sight sight.
In fact, Zhang Yong felt that it was of little use.
Before the invention of the VT fuze, the anti-aircraft anti-aircraft effect of anti-aircraft guns was really terrible.
However, having no effect does not mean it is completely useless.
The biggest effect is to disrupt the flight path of enemy aircraft, forcing the enemy to be unable to drop bombs freely.
If there is no obstruction, the Japanese aircraft will bomb from various angles. This will greatly increase the hit rate and cause greater losses to the fortress.
If there are anti-aircraft guns blocking them, the Japanese aircraft will have to dodge and not dare to fly too low. The hit rate will naturally be greatly reduced. In fact, the effects are mutual.
I may not be able to hit you. However, you don't dare to get too close.
Your bombing effect will also be greatly reduced. This is the existence value of anti-aircraft guns.
100 kilometers…
80 kilometers…
The air map showed that the Japanese aircraft were gradually approaching.
There are a total of nine enemy planes. The number cannot be said to be too many, but not too few. They must be a great threat to Jiangyin Fortress.
We must find a way to fight off one or two fights so that the Japanese invaders do not dare to be so arrogant.
The question is, is there a way...
"Commissioner!"
"Commissioner!"
Suddenly, a signal soldier came in a hurry.
It said there was a call from the attendant's room.
"knew."
Zhang Yong frowned and turned to the headquarters.
The waiter's office called at this time, really.
Did you make an appointment with the Japanese invaders?
Enter the command post.
It's still very safe inside the air raid shelter.
According to Du Songyue, even a direct hit by a 500-kilogram aerial bomb would be fine.
Because it is basically at the bottom of the mountain. Above it is the top of a mountain with an altitude of more than 100 meters. Unless the top of the mountain is blown flat, the headquarters will definitely be fine.
However, no matter how strong a fortress is, it is always a passive defense and can only be passively attacked.
"Commissioner."
Du Songyue waved his hand and left with his staff.
The call to the attendant's room was made by Zhang Yong alone. Of course, the others left voluntarily and voluntarily.
Zhang Yong picked up the phone and found that it was a direct confidential phone call between the fortress and Jinling.
The equipment and facilities in this fortress are not bad.
It did take some effort to build it in the beginning. After all, it was the maritime barrier of Jinling!
Previously, during the 128th Anti-Japanese War, the Japanese warships sailed up the Yangtze River and directly threatened Jinling. This incident greatly stimulated Chiang Kai-shek.
This time, the Japanese invaders tried to attack Jinling again. The first priority was of course to defend the Jiangyin Fortress.
"Hello, I'm Zhang Yong..."
"Shao Long. It's me."
"Hello, Director Lin. You called at this time..."
"How is the situation at the fortress?"
"It's okay. It's nothing serious. The Japanese planes are preparing to bomb."
"be safe."
"I will."
"I'll tell you two things. Just know it yourself. Don't tell anyone else."
"clear."
"First, the committee has gone to Hankou."
"knew."
"Second, Madam will be back soon."
"knew."
"that's all."
Director Lin spoke concisely and to the point. After speaking, he immediately hung up the phone.
Zhang Yong held the microphone and was thoughtful.
Two things. Important. But not important.
Chiang Kai-shek went to Hankou. This is inevitable. Jinling is very unsafe.
It is estimated that he does not have the courage like a loving father to dare to stay and bear the burden.
As soon as he left, the defeat of the Battle of Jinling was actually doomed. Even tragedy was doomed. No one could change it.
Huangpu's direct troops only listened to Chiang Kai-shek. They could not listen to someone from Tang Dynasty.
Tang is absolutely unable to command.
There was a huge gap in strength in the first place, and coupled with the internal conflicts, the defenders had no combat effectiveness at all.
Maybe there are one or two troops that can perform well. However, most of the troops are probably weak.
well……
tragedy.
The second thing is that the lady will be back soon.
I found out that the so-called envoys of the nine countries were simply playing tricks on the government.
Others have no intention of actively mediating.
I'm just teasing you.
Since there is no result, it is natural to come back.
The next step should be to work hard to get closer to the polar bears and win their assistance.
Comrade Jianfeng is ready to show off his talents!
After all, I just returned from polar bears.
Polar bear ammunition and the like should arrive soon.
There are also volunteers to assist the China Air Force.
No matter what the deal was behind the scenes, the polar bear did give the government a hand at the most critical moment.
The original German weapons will gradually be replaced by Su weapons. They will be supported until Mustache attacks the polar bear.
The 74th Army originally had German weapons. Later it was replaced by Soviet weapons. Later it was changed to American weapons.
This period of history is full of great twists and turns.
But the historical giant disintegrated internally and was gradually forgotten.
Put down the phone.
"Someone is coming!"
"arrive!"
"After the air raid, immediately organize manpower and clear the dock."
"yes."
"Try your best to send the people in the fortress to the north bank."
"clear."
Du Songyue agreed.
If it is simply sent to the North Shore, it won't be a big problem.
Just send it across the river.
The situation was urgent and there was no time to make any more plans.
If you stay in the fortress, you may be killed. But if you cross the river and go ashore, there is still a glimmer of hope.
"That's it!"
Zhang Yong didn't say much.
Arrive at the side of Huangshan Fort.
Two Oerlikon anti-aircraft gun groups were deployed here.
Single tube.
60 round drum magazine fed.
The biggest advantage is the continuous firepower.
The Sulotong machine gun next door can only use a 15-round magazine. After two bursts, the magazine is empty.
For high-speed moving targets, it is impossible without continuous firepower.
Therefore, Sulotong was gradually eliminated. Oerlikon gradually became the protagonist.
After the outbreak of World War II, this Oerlikon 20mm cannon was widely used by the Allies and the Axis Powers.
30 kilometers…
20 kilometers…
The Japanese planes were getting closer and closer.
Zhang Yong checked the radar map and found that most of the people in the fortress were hiding.
Including those ordinary people who came in to take refuge, they were also placed in the trenches outside. The trenches were in the shape of "Feng" or "M", which can effectively defend against air attacks.
Of course, bombing and strafing by Japanese aircraft will definitely cause casualties. The question is how many.
We still need to find ways to evacuate the people as soon as possible.
Since Jinling cannot receive it, then move it to the Jiangbei area. Go to Yangzhou, Taizhou, Nantong and other places. Then move it further to the rear.
Opposite Jiangyin Fortress are Jingjiang, Taixing and other places. As long as they are sent across the river, they will be safe for the time being.
As for the future, we will talk about it later. Zhang Yong has no better way.
10 kilometers…
Japanese aircraft appeared in the telescope.
"Coming!"
"Coming!"
The observation post immediately sounded the alarm.
All the machine guns were in readiness. The team leader was very nervous.
Zhang Yong is also silently studying the empty finger map.
It is unrealistic to expect other people to achieve results by playing blindly.
Planes are not ground targets. They cannot be hit casually. Otherwise, they would have been eliminated long ago.
Even at a speed of about 300 kilometers per hour, it is actually very fast. Ground firepower cannot catch up. Unless there is system help and preparations in advance.
In short, it is waiting for you in front. Lock your route, and then attack suddenly.
There are many variables that need to be calculated here.
The speed and altitude of the aircraft...
The muzzle velocity and angle of the machine gun...
It's simply not something you can handle mentally.
Mental arithmetic is just a rough estimate, the so-called lead time.
However, there seems to be no clear guidance on how far in advance. We can only rely on experience.
Or rely on guessing and hope that the blind cat will encounter a dead mouse.
5000 meters…
The Japanese aircraft began to disperse.
The radar map indicated that there were 150 kilograms of aerial bombs hanging from the aircraft.
They are all 150 kilograms. There seems to be no other with larger tonnage. I guess the Japanese invaders thought 150 kilograms was enough.
"Boom, boom, boom..."
"Boom, boom, boom..."
A Suratung machine gun started firing.
Their purpose was not to shoot down but to disrupt the formation of Japanese aircraft.
Let the Japanese aircraft realize that the fortress itself has air defense. They cannot be so carefree. If they are not careful, they will be shot down.
"Boom, boom, boom..."
"Boom, boom, boom..."
There was another Oerlikon cannon fire.
Sure enough, affected by the anti-aircraft firepower, the Japanese aircraft hurriedly dispersed to both sides.
"Rookie..."
Two words came to Zhang Yong's mind.
It seems a bit arrogant. However, this was indeed the case at the time.
The Japanese carrier-based aircraft pilots were undoubtedly trained very hard. However, they really did not have much actual combat experience.
For most of the Japanese pilots, the Songhu battlefield was their first experience in actual combat.
It's mainly a large-area bombing. It doesn't require high accuracy. It's probably just a matter of dropping aerial bombs.
However, facing the Jiangyin Fortress, precision bombing must be carried out.
It must be blown up to the gun emplacement.
The impact point needs to be at least ten meters away.
If an aerial bomb explodes ten meters away, it may not cause fatal damage.
After all, a fortress is a fortress. It is made of reinforced concrete. Especially the gun emplacements are quite strong and will not be easily blown to pieces.
This requirement is a bit high.
To accurately bomb each gun emplacement, both skill and luck are indispensable.
You may have to pay a considerable price.
Your bombing angle and the fortress are also pre-judged.
Normally, this bombing angle would be blocked by anti-aircraft guns.
Sure enough, Japanese aircraft flew over from high altitude.
No bombs were dropped.
The height is too high, more than two thousand meters.
Dropping bombs at an altitude of two thousand meters and trying to hit the gun emplacement is a complete fantasy.
Therefore, the Japanese aircraft will definitely find ways to lower their altitude and avoid anti-aircraft fire as much as possible.
This height must be below 800 meters.
Planes circle.
return.
Trying to dive and drop a bomb.
There are aerial bombs falling. It should be tentative.
The main purpose is to intimidate. Try to put pressure on the fortress and cause chaos.
"Rumble..."
The bomb hit the ground and exploded.
On a slope.
Nothing exploded. 100% waste.
However, the violent explosion caused the nearby ground to shake violently, bringing with it the smell of death.
For the people hiding in the trenches, the violent explosion indeed brought a very heavy pressure to them. They were all frightened.
"boom……"
"boom……"
At the same time, more shells fell.
It was the two destroyers of the Japanese invaders who fired their guns in an attempt to lure the snake out of its hole.
Their purpose is to attract national army gunners to fire coastal defense artillery, and then be killed by aircraft bombs.
It cannot blow up the cannon temporarily, but it can kill the gunner. It is also effective.
Skilled gunners are not easy to train. After suffering a large number of casualties, it is difficult to make up for it in a short time.
However, Zhang Yong was not fooled.
No coastal defense artillery counterattack was ordered.
Explode as you wish.
The 127 mm small water pipe is not afraid of you.
Let you enter the five-kilometer shooting range. It won't be too late for me to fire again. I'm afraid you won't dare.
In fact, the Japanese warships did not dare to approach any further.
Because if you continue to get closer, once you are counterattacked, you won't be able to run away even if you want to.
It can only be harassed by firing artillery from a long distance.
The focus is still on the plane.
"boom……"
"boom……"
Aerial bombs continued to fall one after another.
Some Japanese aircraft launched an attack and dropped bombs at an altitude of 1,000 meters.
"Boom, boom, boom..."
"Boom, boom, boom..."
Ground anti-aircraft fire continued.
But no aircraft was hit and no ground targets were bombed.
Both sides seem to be wasting ammunition...
"Commissioner?"
The group leader is eager to try.
The other artillery groups opened fire. But they did not move.
Zhang Yong ordered them to remain silent.
As a result, the three Oerlikon cannons never fired a single shot.
Zhang Yong didn't know what to do.
But subconsciously I felt that I should be able to do something.
"etc."
Wave your hands. It is strictly forbidden to fire.
There is no danger at the moment. There is no need to expose the machine gun position.
[The construction progress of the empty finger part is 65%]
Suddenly, a system information prompt arrives.
Zhang Yong:……
Indifferent.
It's of no use anyway.
Unless the construction progress is 100%...
But I soon discovered something was wrong.
After the system prompts, the empty finger map changes.
On the map, the predicted flight routes of the Japanese aircraft appeared. They were all red dotted lines.
On the ground, there is a sign of artillery. There are many parameters next to it.
After studying for a while, Zhang Yong understood. This was the key data for the machine gun to shoot down the plane.
His IQ was tight and he couldn't calculate so much data. So the system did it for him. It gave detailed data and he just copied the homework.
"good!"
"good!"
I felt energetic immediately.
Stupid people have stupid blessings.
If you are too smart, you have to feed yourself. You have to work hard on your own.
If you are stupid, you can be lazy and wait for the system to help. As a result, the system really can't stand it anymore and gives the answer directly.
"preparation!"
"Height 39!"
"Direction 218!"
Zhang Yong quickly reported the data.
Actually there is a lot of data. This is the preference.
The gunner immediately adjusted the parameters.
"complete!"
"complete!"
"complete!"
All three machine guns have been set up.
Zhang Yong waited silently.
Because there is also a time parameter.
Eight seconds...
Five seconds...
"fire!"
"fire!"
"Burn all the ammunition!"
A roar.
The three machine guns opened fire in unison.
"Boom-boom-boom!"
"Boom boom!"
The muzzle violently sprayed flames.
According to Zhang Yong's request, burn all the ammunition.
Each gun has 60 rounds of shells. If they are all fired, that's 180 rounds.
If you can shoot down an enemy plane, it's definitely worth it.
The problem is...
A fireball burst into the air.
Oh, no problem. The Japanese plane has been hit.
good!
good!
The system does the work for you, which is really great.
In this life, he has relied on the system to stay alive. Otherwise, he would have died in the first three minutes.
"Hit!"
"Hit!"
The gunners all shouted excitedly.
They were actually stunned for a moment at first. Obviously they didn't expect that the first hit would happen.
The first time the gun was fired, it successfully hit the target.
It's so perfect.
So awesome!
The Commissioner is really a god!
Sure enough, everyone said that if you fight with the Commissioner, you will never lose.
No, others have been shooting for a long time and fired so many shells, but none of them hit. The specialist reported the parameters and hit immediately. Do you think this is a coincidence?
"Change the drum!"
"yes!"
The gunners moved quickly.
All the thieves were so excited that they jumped three feet high.
Even if an aerial bomb exploded nearby, he didn't care at all.
"Hit!"
"Hit!"
The entire fortress was shouting excitedly.
There is no doubt that shooting down a Japanese aircraft gave everyone a great encouragement.
