Let's start with the casualties:

The 2,000 elite field troops of the Japanese army lined up in a neat pace, all the devils were unified, fully armed, strutting forward, lined up in a long line, and trotted quickly through the canyon passage of the first line of sky.

This is the main reinforcement of the second batch of devils to arrive.

If the first batch of reinforcements passing through the first-line Sky Canyon Pass, although they learned that the vanguard mobile troops had successfully occupied the first-line Sky Canyon Pass, and were on guard along the way to ensure the safety of the main force when passing through the canyon pass, they were still slightly worried.

Knowing that the first batch of the main force had passed through the first line of the second batch of the main force of the Japanese army, there was no more anxiety in this regard.

As a result, 2000 Japanese troops, mixed with artillery units and baggage units carrying military vehicles.

When the main force has just marched to the central area of the entire canyon pass.

Like a thunderbolt in the clear sky, like thunder in the night.

Everything came so abruptly and sharply, with the sound of violent explosions sounding from the peaks on both sides of the sky, as if the sky had collapsed, and then a large number of boulders rolled down from the cliffs that were erected dozens of meters high.

For a while, it was like a hammer smashing small meatballs, but all the devils who were hit by boulders, even the armored cars and cars traveling by the devils, without exception, were all smashed into pulp.

The boulder, which carried the power of ten thousand pounds, fell down fiercely from a height of dozens of meters.

It was as powerful as a cannonball falling from a high altitude.

In the midst of the shaking of the heavens, the Japanese army, known as the trump card of the 36th Division, faced the falling disaster like heavenly punishment, and all the obstacles they made were tantamount to shaking the tree.

In the dust, the boulders continued to fall, and the enveloping range was quite exaggerated, covering almost the entire central area of the first-line Sky Canyon Passage, and the passage with a depth of nearly two or three hundred meters.

The Japanese soldiers in the middle of it had no time to effectively dodge, and the only thing they could do was to quickly approach the cliffs on both sides, trying to find a gap where they could survive.

But those gaps are very few after all.

The boulder was mixed with rubble, and after the dust had fallen, very few Japanese soldiers survived within the confines of the cover.

In just a few minutes, a long line of more than 2,000 soldiers of the elite Japanese army was swallowed up by nearly 1/4.

Nearly 500 elites were wiped out in an instant!

！

This is not a simple number, the 500 elite Japanese army wants to destroy it in one fell swoop, and its difficulty is quite exaggerated in the entire Sino-Japanese battlefield.

Far from it, let's just say that it was regarded by the chairman as the most humiliating battle of Zhongtiao Mountain in the history of the War of Resistance Against Japan.

Both sides committed hundreds of thousands of troops.

In the end, according to the casualty data released by the Japanese army after the war, the devils died only five or six hundred people.

What does it mean?

In other words, the boulder in front of him fell in an instant, and it directly smashed all the achievements of the Jiang army in the entire Zhongtiao Mountain.

In this way, do you dare to underestimate the results of the destruction of the elite of the 500 Japanese army?

In the temporary headquarters of the Japanese army in the rear, that is, the headquarters of the 36th Division of the Japanese Army, the supreme commander, the commander of the Devil's Major General Brigade, was also shocked when he heard the news.

This time, he was ordered by the division headquarters to lead 6,000 elites, taking advantage of the fact that the main force of the Eighth Route Army was basically pinned down in the 385 Brigade base area.

The attention of the Eighth Route was distracted by the winter offensive of the 386th Brigade troops, and suddenly launched a surprise attack in the direction of Huangyadong.

After arriving at the Yellow Cliff Cave of the Eighth Route Army, the only one to enter the passage.

Although he learned that the Ray of Heaven Canyon Passage had been firmly controlled by the Vanguard Mobile Force, the devil major general still chose to act cautiously.

He divided the troops he brought with him into three groups, each with about 2,000 men, and quickly passed through the canyon passage of the first line of heaven in turn.

He still understands the truth that you can't put your eggs in one basket.

Then, in the midst of the slight apprehension of Major General Devil, the first batch of main forces passed through the canyon passage smoothly, which made Major General Devil breathe a long sigh of relief.

It was thought that the next march of the troops would be foolproof, but after the second group of main forces entered the central region of the first line of heaven.

Unexpectedly, such a change occurred.

When he saw the boulders rolling down and the dust flying above the entire first-line heavenly canyon, this devil major general subconsciously thought that a natural disaster had occurred.

Didn't you just happen to encounter an earthquake?

But then, with the roar of a series of explosions coming from both sides of the mountain, he realized that this was not a natural disaster, but a man-made disaster.

Absolutely damn it, the cunning Eighth Route Army, with some explosives placed on both sides of the mountain in advance, deliberately triggered the collapse of the mountain in front of them.

With the help of the unique terrain of the first line of sky, after the sudden explosion caused the collapse of the local mountain, the rockslide caused by the sudden explosion is undoubtedly a huge disaster.

And it was the unlucky little devil who was in the middle of the canyon who suffered this disaster.

In the midst of the horror and panic of the Japanese army, this natural disaster caused by the Eighth Route Army lasted for five or six minutes, and then it was nearing its end.

At this time, the second group of the 36th Division marched to the gorge passage of the field elite.

It's like a long snake that has been cut into two pieces directly, and a large part of it has been brutally erased.

The piled boulders were mixed with gravel and mud, rising high, lying in the center of the canyon passage, and in the direction of approaching the entrance of the canyon passage, more than 500 Japanese soldiers who fled back in a hurry were in the aftermath of the disaster, looking at the canyon passage that was completely blocked, and their hearts were full of joy.

And on the other side of the completely blocked boulder.

There were nearly 1,000 Japanese troops, and they looked at the completely blocked passage behind them with a shocked face, as well as the main force that was divided.

So far.

The only passage from the outside of the Yellow Cliff Cave to the inside of the Yellow Cliff Cave, the first-line Sky Canyon Passage, was completely blocked by the falling boulders.

Inside the Yellow Cliff Cave are the vanguard mobile units of the Japanese army, a team of three or four hundred people, as well as the first batch of more than 2,000 elite Japanese troops who successfully passed through the canyon passage, and more than 1,000 Japanese troops who are isolated at the entrance to the first-line sky at this moment.

A total of more than 3,000 elite Japanese troops.

Under the sudden change of the first line of days, the frightened little devils have not had time to make the next move.

The devils, who were completely isolated behind the falling rocks, were about to try to use the radio to contact the command department.

There were angry devil officers with small groups of Japanese troops, trying to find out the culprits who were hiding in the mountains on both sides and using explosives to cause the collapse of the mountains in front of them.

A new round of attacks came suddenly.

"Fire, fire, shoot me!

！ ”

A kilometer away, in the open space where a certain uplifted hill was located, artillery pieces were lined up, and Regiment Commander Cheng, commander of the 772nd Regiment, one of the two old main regiments of the 386th Brigade, was standing on the side, trembling with excitement, and roaring to give orders.

From the telescope, it was observed that a line of mountains and rocks fell, the canyon passage was completely blocked, and more than 1,000 Japanese troops were blocked at the tail of the canyon passage, which was panicked.

Captain Cheng was excited.

He sighed in his heart that Lao Kong was insidious, taking advantage of the precipitous terrain of the first line of sky, just this round of mountain collapse, at least hundreds of little devils could be taken away.

Then, noticing that those little devils were trying to leave from the first line of heaven, how could Regiment Commander Cheng let go of this great opportunity, and immediately gave the order to open fire.

This time, the defense battle surrounding the interior of Huangya Cave was commanded by the deputy chief of the general staff of the Inner Line Defense Region.

In addition, the defense line is divided into three lines.

Among them, the outer line defense area is dominated by the 772nd Regiment, and the newly formed 5th Regiment is also assisted, and Commander Cheng is fully responsible for commanding the Japanese troops entering the outer line area.

The central line defense area was defended by the main forces of the two regiments, including the commander of the 771st Regiment Xu and the commander of the newly formed 17th Regiment, Jiang Regiment.

The inner line is fully defended by the headquarters special service group.

At the same time, the artillery units in various places coordinated operations, using the artillery group offensive that had been built up long ago, and cooperating with the defending troops to launch the sharpest blow to the Japanese troops who broke into the interior of Huangya Cave.

In the words of the deputy chief of the general staff: "Although the defense of Huangyadong this time is a defense, it is more of an offense!"

Our purpose is not only to defend the Huangyadong base area, but also to defend our Huangyadong Arsenal.

It is even more necessary to do everything possible to exterminate all the enemies who will be committed in the future, and leave no one behind! ”

Suddenly the sound of artillery exploded.

It was a cannon group built on the outer line, and it was a fierce bombardment.

There were seven or eight 75-mm mountain guns, plus some infantry guns that were easy to hide.

There is even a 150-mm howitzer gun group.

When the devil retreated from the first-line heavenly canyon passage to the entrance in a panic, an artillery scout passed the direction of the devil to the artillery team in time.

"No. 1, it is the No. 1 target area, the enemy army has about a brigade, and the current strength is gathered, and there is no time to disperse, so I request full firepower coverage of the target area!"

Boom –

Bearing, distance, elevation, wind direction, humidity, elevation angle, ruler, dense position......

The first should shoot Zhu Yuan has long been adjusted by the artillery in advance, and even the number of projectile packs and shells to be used in the No. 1 target area have been planned in advance.

In order to build a full range of artillery fortifications inside the Yellow Cliff Cave.

The soldiers of each artillery unit were strict with themselves, and even made corresponding secret tables for each target shelling point in advance.

Even in the most rigid way, every shell must be accurately projected into the predetermined shelling area in the shortest possible time.

The next moment, the roar of shells joined in one piece.

The natural disaster caused by the collapse of the mountain caused by the Eighth Route had just experienced the Japanese army, which was in a hurry like a tide pouring out of the entrance of the sky, and then ushered in an even more tragic bombardment.

Enjoying the scene of the devils crying wolves in the area covered by fire from the telescope, Captain Cheng became more and more excited.

"Talking and laughing, it's nothing more than that, nothing more than that!"

Lao Cheng clenched his fists excitedly.

Since he knew that Li Datou was learning culture every day, Captain Cheng was not willing to lag behind, and with these hours of study, the effect was really extraordinary.

Otherwise, I would not have been able to say such a suitable word.

The battalion commander on the side also held a telescope, but he felt a little pity:

"Regiment Commander, according to the situation we have detected, the devils took the lead in advancing into our Huangya Cave this time, and there are nearly one brigade of elites, and this is the second batch of troops that the little devils put in.

If you want me to say that you should put this entire devil brigade into the Yellow Cliff Cave, let's clean him up in one go.

It's still too early to blow up! ”

Regiment Commander Cheng, who was still in excitement, glanced back at the battalion commander and said:

"When did you kid learn to speak big?

The little devils are not muddy, and at the moment, there are already two or three thousand devil elites who we put in one go, and if there are too many of them, we may not be able to afford it.

Our arsenal cannot afford to be lost, it is better to be safe.

In addition, when we eat meat, we have to leave some soup for others to drink.

There are still more than a dozen regiments waiting to eat meat on the periphery of Huangya Cave, let's lock all the little devils inside Huangya Cave in one go, and then those regiment leaders will not be in a hurry with us! ”

The first battalion commander nodded: "This is also true!" ”

"Regiment Commander, the battle on our side can be regarded as officially started, and I don't know what happened to the team brought over by Commander Li and Commander Kong of the Northwest Military Region, and whether they can successfully complete this surprise attack plan."

"Why don't you kid open any pot and mention which pot?" Head Cheng suddenly scolded: "Grandma, why is it his turn to be Li Yunlong's head for all good things?"

If you want to say that we are fighting a defensive battle here, how can it compare to the pleasure of him Li Yunlong leading a mobile force to attack the base camp of the devil? ”

"But Commander, do you know how to command a mobile unit?" The commander of the first battalion blurted out a question.

Then I realized...... Sloppy.

Captain Cheng was really anxious, and said angrily: "Rabbit cub, how do you know that Lao Tzu won't?" Lao Tzu won't, can't he learn yet?

He Li Yunlong is capable, and I am as capable as Lao Cheng! ”

After scolding and scolding, Regiment Commander Cheng gave an order: "Okay, let's get down to business, after this firepower is covered, the devils will at least have most of the casualties, and send a few troops to detour up from the left and right flanks, and take the opportunity to eat this devil in one go."

In addition, another unit was divided to advance to Lao Xu's central defense area.

It is estimated that in the direction of the central defense area, Lao Xu has already done it with the first batch of troops of the devil. ”

"Yes!"

And just after the two changes in the first line of the sky happened one after another.

The information obtained by the devil Shaozuo, who advanced with the vanguard mobile unit, was also transmitted to the headquarters of the Japanese brigade and regiment far away from the front line.

"Nani? What Tian Song means is that Balu has been prepared inside the Yellow Cliff Cave for a long time, and even dug a trap in advance, waiting for us to jump into it ourselves? ”

The commander of the Devil Brigade who learned such news was stunned.

But think about it carefully, if you hadn't been prepared in advance, how could there be a scene of the collapse of the Tianshan Mountains in front of you?

A violent artillery bombardment followed from inside the Yellow Cliff Cave, and the sound was definitely not the artillery held by the second group of main forces.

Could it be the attack of the Eighth Route Army?

Under the cover of dense firepower, the second group of Japanese troops who fled in confusion had no time to deliver the news.

The captain of the devil brigade who led the team saw that the artillery attack of the Eighth Route Army was coming suddenly, and there was almost no cover around, and even if he hid back in the canyon pass, he would also be pursued by the artillery shells of the Eighth Route Army.

He hurriedly ordered to advance in the direction of the mountain inside the Yellow Cliff Cave, first find a bunker, and build a fortification......
