The artillery fire continued for a very long time, and did not stop until the Germans landed on the coast.

The British soldiers were smothered in the fortifications by the heavy artillery fire, and only the pillboxes with perforations ventured to spit tongues of fire.

"Boom!" A Makqin hidden in a bunker had just let go of a few German soldiers when a huge explosion sent the bunker into the sky.

The British were amazed to learn that the bunker was a meter thick reinforced concrete. What kind of cannon is this, it actually hit the soul with one shot, and blasted the pillbox into the sky with the people and machine guns inside.

"At such a close distance, firing with the front main gun, let alone a reinforced concrete bunker, even a pure steel bunker can't stand it."

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

As long as it is a bunker on the coast, there is nothing that cannot be done. If it really can't be done, then two shots.

Of the 480 mm naval guns, the shells weigh one and a half tons.

Moreover, the current four-hundred-eighty-mm shells are of an improved version.

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

As long as the caliber is large enough and the charge inside is enough, no matter what fortification bunker has to rest.

But after actually surveying the battlefield, weapons researchers discovered a very embarrassing thing. That is, because the caliber of the shells is too large and the weight is too heavy.

When fired, it will cause the cannonball to smash into the dirt before exploding.

Most of the time, the shells were able to hit seven or eight meters deep into the ground. In some cases, it can even be smashed into a depth of ten meters.

It smashed so deep that it blew up all the dirt around it. The kinetic energy of the bomb erupts in an inverted trapezoidal shape, which greatly reduces the lethality of the surrounding area. In other words, most of the blast power was absorbed by the soil.

This leads to a significant reduction in the power of the shell, and the greater the caliber, the greater the effect on the power.

According to the battlefield survey, the Jinzhou Artillery Research Institute immediately began to work hard to tackle key problems.

Research and research, it turns out that the instantaneous fuse is not sensitive enough.

Although it is an instantaneous fuse, it can be used to ensure that the cannon will not explode if it touches something. As a result, the instantaneous fuze actually has a certain delay.

This delay may not be much for light artillery, but it is lethal enough for a gun with a large caliber shell of more than a ton.

Because the heavier the shell, the deeper the crater it will be.

Xu Erjue thought about it for a long time and finally came up with a solution. That is the hypersensitive fuze, and this hypersensitive fuze is excited by the muzzle velocity of the cannon chamber.

With this hypersensitive fuse, the shell becomes extremely sensitive. Not to mention smashing into the dirt, even a thick branch scraped during flight will explode.

The development of such shells first fell on the heads of the British army.

The British pillboxes are now being bombarded with shells with hypersensitive fuses.

A bomb weighing one and a half tons, there was no process of penetrating deep at all. Instead, it exploded almost close to the ground!

The radius of destruction has been greatly increased, and even the shock wave after the explosion has been much larger than before.

Many British soldiers cowered in the anti-artillery holes on the edge of the trenches. Normally, these anti-artillery holes are quite strong.

As long as there is not a direct hit from a howitzer of more than one hundred and fifty mm caliber, there will not be much of a problem.

This is now a four-hundred-eighty-millimeter howitzer!

A shot fell, hitting the ground and exploding.

The effect of air vibration is far from being comparable to that of the original shells.

What often happens is that a shell explodes. The people in the trench will never be able to get out again!

When they came out of the deeper fortifications to look for them, all they could see was a bloody corpse.

These people were not blown up, but shocked to death.

Moreover, the range of the shock wave from the explosion increased significantly.

There won't be a living person in a place the size of a whole football field.

Only those who stayed in the fortifications ten meters deep underground were spared.

The shells were not officially over until the Germans rushed to the beachhead, and a shell fell into the German crowd, killing a full squad of German troops.

The only thing left was for the destroyers to shoot at close range for artillery support.

As soon as the cannon fire stopped, countless British soldiers rushed out of the underground fortifications.

They fully studied the tactics of the Ming army's artillery shells to wash the ground, so they all hid in the underground fortifications ten meters deep during the shelling.

Only a few observation posts remained above the positions, and the shell washing did not affect them much.

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

The machine gunner didn't care about any point shooting at this time, but desperately strafed it.

The bullets rained down in pieces, directly knocking the German soldiers who rushed in front to the ground with flesh and blood.

Looking at the soldiers in front of them, they fell as if they were cutting wheat. The German soldiers in the back could only hide under a dirt slope on the beach, which 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 mortar to fire!

This small dirt slope was actually deliberately set aside by the British army, and the firing of the artillery guns had already been calculated. Even every cannon has been test-fired here.

The British mortar shells, as if they had eyes, exploded one or two German soldiers every time they hit the ground.

Farther away, the last remaining large-caliber mortars and howitzers of the British army are desperately bombarding the boats on the beach!

Many ships were hit by shells, and immediately billowing smoke came out. In the thick smoke, you can see the orange flames constantly steaming and jumping.

"The British are really good, and they can hold it to this extent." Li Xiu put down the binoculars and nodded affirmatively.

"The military literacy of the British army is indeed not low, I heard from the army. On the battlefields of Russia, the British did not fare badly either.

At least it was a grade with the French army, but their troops were much smaller than the French army. ”

"Their brigade is stationed in Gibraltar and does not allow our navy to leave Gibraltar.

Hehe! Britain is an island country, and if it is okay to be hit by our warships, it will be fired a few shots. That day is over!

So! Gibraltar was their lifeline, and if it weren't for the ruthlessness of the eldest brother, more than a million people were conscripted at once to build the train line from Algiers to Marrakech.

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

After the port of Marrakech was built, the British already knew that they had lost the war completely.

If you don't surrender, you can only wait to be starved to death. After Li Xiu finished speaking, he continued to pick up the binoculars and look into the distance.
