Outside the city of Chengde.

On the defensive positions of the 1st Division of the Japanese Army.

Under the scorching June sun, the devils carried shovels and hoes and dug positions under the command of officers.

Sweat it out.

Visible to the naked eye, infantry trenches, machine-gun forts, ring fortifications, anti-tank fortifications, anti-tank trenches, barbed wire, and anti-artillery holes, a complete set of fortifications began to be spread along the city walls, and then spread out layer by layer.

"It must be reinforced, you know?"

Kotaro Hattori personally inspected and told him:

"The stronger the better, the thicker the better, especially the anti-artillery holes, must be in accordance with the highest standards, the number of wooden beams and the thickness of the soil layer can not be reduced in the slightest."

In the past, Chengde was the core occupation area of the Japanese Empire, and there were only a small number of guerrillas around, and the threat was pitiful, coupled with the weak firepower of the Republic of China troops, there were few mortars, so the Chengde garrison only built some simple fortifications.

It can only defend against light infantry attacks.

And now, the Independent Regiment of the Eighth Route Army is coming to attack.

This unit is more ferocious than the division of the first class, heavy artillery, tanks, aircraft, everything, and even more than two hundred caliber heavy artillery, especially artillery, I don't know how many times more luxurious than the heavy artillery brigade of the Japanese Empire...

The ammunition is also outrageous.

Even if he is the first division, the divisional artillery is one of the best in the empire, and the upcoming Kwantung Army artillery brigade is supported, but the artillery battle against the independent regiment still has no chance of winning.

The gap is too big.

Hattori had no choice but to fortify his position and set strict digging standards in order to preserve as many soldiers as possible under the powerful artillery bombardment before the enemy attacked.

The first division was elite, and the soldiers had rich combat experience, which created a strong combat effectiveness of the division, but it also made it more difficult to replenish the soldiers, because the excellent soldiers of the empire were almost exhausted.

Once the casualties are too large, it will directly affect the combat effectiveness.

Even if there is a lack of concrete and steel bars, the soot mixed soil can achieve a high hardness, and if it is not good, it can also be used as a support frame with wooden beams, and the soil layer is filled, and the quality is not good.

According to Hattori's idea, important fortifications, especially civil forts and anti-artillery holes, should be able to withstand direct hits from the Imperial 240 howitzers, that is, from the new super-caliber mortars of the Separate Regiment.

Other fortifications are as multi-layered, deep, and wide as possible.

In this way, the terrorist shelling of the independent regiment can only destroy its fortification system, and cannot mass-kill the grassroots soldiers, and even ordinary fortifications will have a lot of remnants due to their width and depth.

As for the plane, Hattori thought about it, but there was really no need to worry too much.

His first division has anti-aircraft firepower, although it is not enough to deal with the number of locusts in the independent regiment, but it can also hold up the air umbrella a little, and the power of the bombshells is indeed terrifying, comparable to naval artillery, but the scale and number of bombardments, and the duration of the bombardment, are far less than that of large-scale running groups.

The accuracy is also a little worse.

As long as the losses are not large, he can use strong positions to kill and injure enemy tanks, and mass-kill the soldiers of the Independent Regiment by means of street fighting, so as to consume the offensive power of the Independent Regiment and finally block the attack.

After inspecting the positions, it was found that all the positions were all under construction according to the requirements, and Hattori Kotaro left satisfied.

And then just as he was inside the city walls.

Boom...

A violent explosion rose from the position outside the city, and the smoke of the explosion was accompanied by a shock wave, and the ground was blown away with dirt, rubble and wood, mixed with the stumps of several devils.

When the smoke cleared, everyone saw that an elliptical crater three and a half meters deep and ten meters in circumference appeared in the center, and a half-buried civil fortification built according to the highest requirements at the original crater had disappeared, and a large number of pine chips were scattered around it.

"Plane bombing?"

The violent sound alarmed and alarmed Kotaro Hattori, and the moment he looked back and saw the crater, he subconsciously thought.

Whether it is the sound of the explosion or the power shown by the crater, the destructive power is far greater than that of the Empire's 240 howitzers, and only the enemy's aerial bombs, and they are bombshells, can be so powerful.

But you didn't hear the plane?

Before the bombing of the planes, there was a distinct sound of propellers, which could not be hidden in any case, and during this period, it was enough for soldiers to hide and hide.

Kotaro Hattori looked up and found no trace of the plane.

It was at this time that boom... Another series of explosions rose up on the positions in front of Chengde, and trenches, communication trenches, civil fortifications, machine gun forts, and even anti-artillery holes were overturned, leaving only craters three and a half meters deep.

"Large-caliber heavy artillery."

At this scene, Hattori suddenly understood what was happening to him in front of him.

The Separate Regiment was shelling his position with oversized heavy artillery, the previous one being calibrator shells.

And the number of super-large-caliber heavy guns of the independent regiment will not be less.

The rate of fire of large-caliber heavy artillery was slow, judging by the number of craters in front of him, at least six or more, and with his deep knowledge, Hattori Kotaro even guessed the caliber of the artillery of the independent regiment - more than twelve inches.

Because the crater in front of him is more powerful than the twelve-inch naval gun of the navy.

The black gold charge, the large charge of the alloy warhead, and the heavy projectile made the new 305 gun of the independent regiment comparable to or even surpassed the naval gun.

Then, a thought flashed through Hattori's mind.

Big trouble!

The main fortified bunkers of Chengde were built according to the standard of 240 howitzers of the Resistance Empire, with anti-artillery holes and semi-buried civil fortifications in order to maximize the protection of troops.

To build these fortifications, he ordered his troops to gather all the timber they could in the surrounding area.

As for the construction of stronger fortifications - with the terrain around Chengde, the bunkers that could withstand the twelve-inch heavy guns, either reinforced concrete fortifications or strong deep tunnels with supporting structures.

He didn't have the supplies, and he didn't have the time.

Now I just hope that tonight's night raid will achieve its intended goal.

Hattori prayed silently in his heart—thinking about it, he also knew that the goals he had set for the night raid troops would be difficult to achieve.

······

That night.

Although the sky was cloudless, there was no moon tonight, and it was pitch black.

Outside the sincerity.

On the edge of Ping County, the station of the Independent Regiment, a guard post located on the peak of the mountain.

"Squad leader."

"The little devil is coming."

The fighters on duty spotted the devils passing through the mountain through infrared night vision.

Although the devil did concealment, wore branches on his head, lowered his body, and picked the most hidden night two o'clock to pass, and acted very carefully, but in the face of strong infrared light and night vision devices, he was meticulous.

"How many?"

As he spoke, the squad leader turned on the radio in his hand, and his tone was calm and even relieved.

The devil is finally here.

Ding Wei knew from the beginning that the devils would definitely launch a night attack, so he had already prepared and set up hidden observation posts on various hills.

The debriefing warrior said:

"There are too many to estimate in detail, but more than two brigades."

The infrared night vision device is essentially a searchlight, because it is observed through a special sight, so the angle of view is more limited than that of an ordinary searchlight, but the guards are elite scouts, and they can roughly figure out the scale of the devil.

"Two brigades."

While sending the news to Ding Wei, who was located in Jiao County, the squad leader squinted his eyes and said in a somewhat excited tone.

Although he is a squad leader, his frequent cultural study and military knowledge study have made this squad leader's vision also good, and he knows very well that there can be only one way in a night attack.

There can be two brigades of devils here.

In other words, this time a big fish has entered Pingxian.

······

"Commander."

Jiaoxian, Ding Wei Headquarters:

"Devils have been found on the left flank, at least two brigades."

"Devils were also found on the right wing, and they were also the size of two brigades."

"These two gangs of devils are currently advancing along the mountainous area on the edge of Jiaoxian County to the warehouse area."

"It's finally here."

Hearing the news, Ding Wei's eyes lit up.

Because of the strength of the troops, as well as a large number of recruits to run in, and new mechanized equipment to be familiar, he really can't attack at present, although the warehouse solves the problem of logistics and supply, but it still takes a lot of time for a large army to run skillfully and unify the command.

Besides, in addition to weapons and equipment, the devil's other strength is really not bad, and he doesn't want to have problems because of rashness.

So when the devils take the initiative to attack, it is the best choice for them to wait for work.

"Order the third battalion of tanks, the fourth battalion, the twenty-seventh, twenty-eighth, twenty-ninth infantry to sortie."

Ding Wei gave the order:

"Destroy these devils."

"All the security and reconnaissance posts will report the location of the devil at any time."

"In addition, the newly formed 54th Battalion, 55th Battalion, 56th Battalion, 57th Battalion, and 58th Battalion will guard all key points of transportation and completely surround the devils."

The new No. 4 tank has been equipped, although the armor, power, etc. have not been improved, but the addition of night vision devices allows the tank to directly rely on night vision devices to fight, and the driver, commander, and gunner can directly observe through the night vision goggles.

The matching armored vehicles are also equipped with night vision devices.

With the advantage of sight, it is not a problem for tank units to go out at night, and there is no longer a need for large-scale use of searchlights.

"Yes."

The staff officer quickly gave the order.

·····

At the same time.

On the other side of the Eurasian continent.

Inside the Stalingrad Tractor Plant.

"How?"

With a creak, as the jeep stopped, a lieutenant general couldn't wait to get out of the car, and then walked quickly into the tractor factory, entered the test site, and found a major general

'Are the test results out?' How did the new tank of the Germans perform? ’

In the huge test ground, a brand new tank was parked at this time, but strangely, this tank did not have any paint on it.

The lieutenant general's tone was anxious:

"Comrade Stalin is still waiting to hear the report!"

Hearing the name of the man who always had a pipe in his mouth, the major general of the armored corps in charge of the test shook his body, and then his tone was very solemn:

"The results were not good."

"The performance of the new No. 4 tank of the Germans has been substantially improved compared with the previous one, and the actual combat effect is probably twice that of the previous No. 4, especially in the hands of the Germans."

"Why?"

Hearing this, the lieutenant general's expression froze.

He knew very well that the major general in front of him was not only strong in mechanical technology, but also an elite tank commander, with more than twenty German tanks.
