The artillery fire lasted for a very long time and did not stop until the German troops landed on the coast.

The British soldiers were trapped in the fortifications by the fierce artillery fire and could not get out. Only those bunkers with perforations spit out tongues of fire at risk.

"Boom!" A Maxim hidden inside the bunker had just knocked down a few German soldiers when a huge explosion sent the bunker flying into the sky.

The British were extremely surprised. You must know that this bunker was protected by reinforced concrete with a thickness of one meter. What kind of cannon was this? It actually hit the soul and blasted the bunker, the people inside and the machine gun into the sky.

"At such a close distance, even a pure steel bunker cannot withstand the fire from the front main gun, let alone a reinforced concrete bunker."

Chen Laohu put down the telescope in his hand with great satisfaction. The battleship's front main gun was still as reliable as ever.

As long as it's a bunker on the coast, there's nothing that can't be fixed with one shot. If it really can't be fixed, use two shots.

The shells of a 480mm naval gun weigh one and a half tons.

Moreover, the current 480mm artillery shells are improved types.

In the past, the Ming Dynasty paid great attention to the caliber of cannonballs and always believed that caliber was justice.

As long as the caliber is large enough and the explosive charge inside is large enough, no matter what kind of fortifications and bunkers are built, they will have to be shut down.

But after actually surveying the battlefield, weapons researchers discovered a very embarrassing thing. That is, the artillery shells were too large in caliber and too heavy.

After the launch hits the ground, it will cause the shell to hit the soil before exploding.

Most of the time, the shells can hit the ground seven or eight meters deep. In some cases, they can even hit ten meters deep.

The impact was so deep that the surrounding soil exploded. The kinetic energy of the bomb erupted in an inverted trapezoid shape, greatly reducing its lethality to the surrounding areas. In other words, most of the explosive power was absorbed by the soil.

This results in a significant reduction in the power of the artillery shells, and the larger the caliber, the greater the impact on the power.

Based on the battlefield survey, the Jinzhou Artillery Research Institute immediately began to work hard on the problem.

After much research, it turned out that the problem was that the instant fuze was not sensitive enough.

Although it is an instant fuze, in order to ensure that the cannon will not explode after it hits something after being ejected from the chamber. Therefore, the instant fuze actually has a certain delay.

This delay may not matter to light artillery, but it is fatal enough to artillery with large-caliber shells exceeding one ton.

Because the heavier the shell, the deeper the hole it creates.

Xu Erjue thought for a long time and finally came up with a way. That is a super-sensitive fuze, and this super-sensitive fuze is activated by the muzzle velocity of the cannon ejected from the chamber.

After using this kind of super-sensitive fuse, the artillery shell will become extremely sensitive. Let alone smashing into the soil, even if it scrapes a thick branch during flight, it will explode.

The development of this kind of artillery shell first fell on the British army.

The British army's bunkers are now being bombarded by artillery shells equipped with super-sensitive fuses.

The bomb, which weighed one and a half tons, did not penetrate deeply at all. Instead, it exploded almost close to the ground!

The killing radius has been greatly improved, and even the shock wave after the explosion is much larger than before.

Many British soldiers huddled in the shell-proof holes on the edge of the trenches. Normally, these gun-proof holes were fairly strong.

As long as it is not directly hit by a howitzer with a caliber exceeding 150 mm, there won't be much of a problem.

This now is a 480mm howitzer!

One shot fell and exploded against the ground.

The air vibration effect produced is far beyond what the original cannonballs can match.

What often happens is that an artillery shell explodes and the people inside the trench bombhole can never get out again!

When they came out from the deeper underground fortifications to look for them, they could only see corpses bleeding from their orifices.

These people were not killed by bombs, but were shocked to death.

Moreover, the range of the shock wave generated by the explosion is greatly increased.

There wouldn't be a single living person in a place the size of a football field.

Only those who stayed in the fortifications ten meters deep underground could survive.

The artillery shells continued until the German army rushed to the beach, and one artillery shell fell into the crowd of German soldiers, killing an entire squad of German soldiers. Only then was it officially declared over.

All that's left is for the destroyers to approach and fire at close range for artillery support.

As soon as the sound of artillery stopped, countless British soldiers rushed out from the underground fortifications.

They fully studied the Ming army's artillery bomb tactics, so they all hid in the ten-meter-deep underground fortifications during the bombardment.

Only a few observation posts were left on the position, and the artillery shells had little impact on them.

But as soon as they entered the position, the German soldiers were already only a few dozen meters away from them.

The machine gunner no longer cared about spot shooting at this time, but fired with all his might.

The bullets sent out a hail of bullets, directly beating the German soldiers rushing in front to pieces.

Looking at the soldiers in front, they fell down like wheat. The German soldiers behind could only hide under a slope on the beach that was only thirty or forty centimeters above the ground.

The military quality of the British army was still good. Seeing that the German soldiers were suppressed, the artillery officer immediately ordered the mortars to fire!

This small slope was actually set aside intentionally by the British army. The calculations for the firing of artillery cannons had long been completed. Even every cannon had been tested here.

The British mortar shells seemed to have eyes. Every time they hit the ground, one or two German soldiers would be blown up.

Further away, the British army's remaining large-caliber mortars and howitzers were desperately bombarding the ships on the beach!

Many ships were hit by cannonballs, and thick smoke billowed out immediately. In the thick smoke, orange flames could be seen constantly steaming and jumping.

"The British are really powerful, they can actually defend to this extent." Li Xiu put down the telescope and nodded affirmatively.

"The military quality of the British army is indeed not low. I heard people from the army say that the performance of the British army on the Russian battlefield was not bad either.

At least they are on the same level as the French army, but their troops are much smaller than the French army."

"Their large forces are all guarding Gibraltar and will not let our navy leave Gibraltar.

Haha! Britain is an island country. If our warships are like this, they will only bombard us with a few cannons. That day will not be easy for them!

So! Gibraltar is their lifeline. If it weren't for the big brother's cruelty, more than one million people were recruited to build the train line from Algiers to Marrakech.

In this way, we have a foothold in the Atlantic Ocean.

After the Marrakech Port was built, the British knew that they had completely lost this war.
Chapter completed!
