At this time, with the collapse of the mountain in the passage of the first line of the Heavenly Canyon, the elite troops of the 36th Division of the Japanese Army, which took the lead in advancing to the interior of the Yellow Cliff Cave, were in a rather awkward situation.

The cunning Eighth Route Army used hidden explosives to attack and blow up the mountains on both sides of the canyon, causing the entire passage to be completely blocked.

Falling gravel and dirt piled up in the central area of the canyon passage.

And this strange terrain of the Yellow Cliff Cave, if you want to enter the inside, this canyon passage is almost the only and most convenient way.

In addition, the Japanese army can also try to climb over the mountains and mountains, from the peaks on both sides of the first line of sky.

It's just that if you have to go over the mountains and mountains, not to mention that it is extremely difficult for the main force with a large force.

Even if one could cross the mountains, the various chariots carried by the baggage troops, including the artillery carried by the artillery units, were difficult to transport through the rugged and difficult mountains.

However, under the premise of losing the advantage of artillery fire, even if they crossed the mountains and entered the interior of Huangya Cave, they could not be the opponent of the well-equipped and well-prepared Eighth Route Army.

At this time, the commander of the Devil Brigade who was in the external temporary command of the first line of heaven was also quite anxious.

In the end, he could only hope that nearly half of the elite imperial troops who entered the interior of the Yellow Cliff Cave could rely on the terrain and terrain to drag down the Eighth Route Army inside the Yellow Cliff Cave.

It would be better if it could directly defeat the Eighth Route Army troops inside Huangya Cave and destroy the Eighth Route Army's arsenal.

If you can't do it, you can at least hold on to the danger and wait for reinforcements from the main forces.

The immediate priority is to reopen the canyon passage in front of us.

If you want to say that the little devil attacked the Huangyadong Arsenal this time, it is still relatively well prepared, and the baggage troops that accompanied the elite troops of the 36th Division also had some special combat vehicles to clear roadblocks.

For example, some light forklifts.

So the commander of the devil brigade made preparations with both hands.

On the one hand, he immediately contacted the command headquarters that entered the interior of Huangya Cave, and ordered his troops to hold on to the inside of Huangya Cave, drag the troops of the Eighth Route Army, and try to launch a breakthrough in the direction of the Eighth Route Army Arsenal.

At the same time, they also sent light infantry up the mountain in an attempt to seize the ridge line of the peaks on both sides of the first line of heaven and guard the passage of the canyon.

The Eighth Route Army, which may be lurking in the mountains on both sides, will be completely wiped out.

It's a pity that Regiment Leader Cheng and Regiment Feng, who have long been defending the outer line of Huangya Cave, how could they sit back and watch the devil's attack and ignore it?

At the entrance of the first-line Heavenly Canyon Pass, the sudden bombardment was over, and Commander Cheng and Commander Feng took the main elite to detour from both flanks and launched an attack on the Japanese army that had not yet had time to gain a firm foothold.

There was no cover in the entrance area of the canyon pass, and the artillery fire of the Eighth Route Army was fierce, and the captain of the devil brigade who led the team did not dare to hesitate, and hurriedly led the troops to fight and retreat under the attack of Commander Cheng and his party, and moved closer to the mountains in the distance.

The canyon passage area was quickly occupied by Captain Cheng and his party.

Then, Regiment Commander Cheng also sent troops, and the soldiers were familiar with the path up the mountain to the ridge line of the mountains on both sides of the first line of sky, seize the high ground, and build fortifications, condescendingly launched an attack on the Japanese troops who were trying to touch the ridge line outside the Huangya Cave.

In order to effectively avoid the direct artillery fire and fierce offensive of the devils.

Commander Cheng ordered the construction of anti-slope fortifications and relied on the mountain to block the attack.

Thanks to the steepness and peculiarity of the mountains on both sides of the first line of sky, the current channel of the first line of heaven canyon was completely blocked, and the Japanese army could not take the ridge fortifications of the mountain for a while.

Inside the Yellow Cliff Cave, the middle line defense area.

As Commander Cheng speculated, Commander Xu, who was in charge of the 771st Regiment stationed in the central defense area, had already led his troops to attack the first main forces of the Japanese army approaching the central defense area.

It's still the old rule, first a cannon raid.

Hit the little devil by surprise.

The devils were the first to enter the more than 2,000 elites inside the Yellow Cliff Cave

, under heavy artillery fire, casualties spread rapidly.

The entire interior of the Yellow Cliff Cave, relying on the three-line defense, perfectly combined with the characteristics of the terrain, the artillery strike range can almost cover all line defense areas.

In the words of the commander of the artillery regiment of the headquarters with a little braggart:

There is a sparrow in this Yellow Cliff Cave, and we can also shoot it down with cannonballs.

At this moment, the little devil has a deep understanding of this.

In the face of the artillery attack of the Eighth Route Army, which almost did not know where to hide, under the sudden artillery fire, the Japanese army hurriedly dispersed the troops in order to avoid the troops being killed and injured by concentrated fire.

However, no matter how their scattered troops moved and dodged, the shells that smashed in mid-air were like eyes, running and hitting wherever they went.

As soon as a clash broke out between the two sides and the position of the Japanese army was exposed, the Eighth Route Army seemed to be able to immediately attract accurate artillery strikes.

In such a situation of being pressed and beaten throughout the whole process, the two devil captains who were shocked called hell.

It's almost like a couple of bombers hanging over your head.

At the same time, they also realized that this time they definitely fell into the trap of the Eighth Route Army, and the inside of this Yellow Cliff Cave was simply a trap circle built by the Eighth Route Army in advance.

Where is there any hint of being a little unprepared and caught off guard in these damn dirt roads?

Commander Xu, who led the team to fight on the middle line, and Commander Jiang of the 17th Regiment had a great fight.

I have never fought such a vigorous battle in my life, and it was completely unilateral firepower, which also gave the little devil a good taste of the grievances of being crushed by artillery fire.

The two regiment commanders sighed in their hearts at the same time: The comrades of the artillery regiment are really powerful, and the hidden artillery group offensive built in advance is as if they have already calculated where the little devil will hide.

As soon as the artillery scouts reported the coordinates and locations of the devils, the shells would soon be smashed down accurately.

This confrontation lasted only more than ten minutes.

The first batch of more than 2,000 elite troops of the 36th Division of the Japanese Army who entered the interior of Huangya Cave were forced to break into pieces under the bombardment of artillery fire, and took shelter from artillery fire in all directions with the help of the cover of the mountains.

After smoothly dividing the devils who were originally gathered together.

Commander Cheng and Commander Jiang did not hesitate any longer, and immediately commanded the soldiers to carry out a roundabout outflanking and annihilation tactic with ease.

Divide into one by one and eat them all.

The drastic change in the situation made the two devil captains who led the team realize the crisis of the situation, and they hurriedly conveyed a communication requesting tactical guidance to the command side.

The commander of the Devil Brigade who was outside the Yellow Cliff Cave was also startled.

On his side, he had not yet laid the ridge line occupied by the Eighth Route Army, and the communication of the vanguard troops in the interior for urgent help was conveyed.

The devil knows what happened to the vanguard inside the Yellow Cliff Cave.

It's a pity that the little devil who is outside the Yellow Cliff Cave at this time is also in a hurry, but he can't help the vanguard troops inside the Yellow Cliff Cave at all.

The only effective means of the Japanese was probably air reinforcement.

Relying on the advantage that the temporary airport in Licheng is closer to Huangya Cave.

The Japanese army's flight unit came very quickly, and after the devil's plane arrived, with the help of bombers and fighters to reinforce the battlefield, the devil's vanguard unit inside the Yellow Cliff Cave barely pulled back a game and temporarily took a foothold.

The bombers of the devils who arrived bombed some of the artillery fortifications of the Eighth Route Army that had been exposed.

The hidden air defense units on the side of the Eighth Route Army also attacked at the same time, engaging the Japanese aviation units.

The fighting between the two sides intensified.

At this time, the first line of heaven was completely isolated, and the only thing that the devils could pose a threat to the inside of the Yellow Cliff Cave were these fighters and bombers.

But I have to say that the only means of the devil are indeed effective.

In the face of the devil's air firepower superiority, the deputy chief of general staff at the command headquarters also had to issue an order to let the artillery groups fortifications everywhere be concealed in time to avoid losses

The air defense forces mainly launched a counterattack.

Being able to lay down a plane counts as one.

Shi Dahu, who stayed inside the Huangya Cave to help, was not idle, and hurriedly led the soldiers to start camouflage in various places.

They took the initiative to expose some fake factories, fake military bases, and fake artillery group fortifications, and lured the devil's planes to bomb them.

With the help of reinforcements from the air, the vanguard troops who entered the Yellow Cliff Cave temporarily formed a confrontation with the side of the Eighth Route Army.

……

The outer line of Huangya Cave.

The Japanese army and the Eighth Route Army opened up a new situation of confrontation.

Before the start of this battle, the Japanese army made a plan, while attacking and raiding the Huangyadong Arsenal, it would use the Huangyadong Arsenal as a bait to lure reinforcements from the Eighth Route Army, and then carry out an ambush operation halfway.

At the moment, the situation seems to be proceeding according to the Japanese army's pre-plan.

However, the confrontation between the two sides that ensued was not as smooth as the Japanese expected.

The reinforcements on the side of the Eighth Route Army did rush towards Huangya Cave, but these Eighth Route Army were quite cunning and did not fall into the trap stupidly.

On the contrary, he sensed the conspiracy of the Japanese army in advance.

The ambush warfare that the Japanese army had originally prepared carefully turned into a positional war between the two sides relying on the terrain.

Soon, the Eighth Route Army, which did not play its cards according to the routine, turned the positional war into a sports war.

The main forces attacked from all sides and did not act in accordance with the rules at all.

Local army units and even militia units have come to the aid of the battle, and they have also shown considerable combat effectiveness.

From the overall level, although the Japanese army occupies a certain equipment advantage, as an elite mixed brigade, the military quality is also not low.

However, the troops of the Eighth Route Army did not confront the Japanese army head-on at all, and fought hard.

The Japanese army also fell into a helpless situation for a while.

Around the direction of the base area of the 385th Brigade of the Eighth Route Army, some units mainly composed of the 3rd Mixed Brigade of the Japanese Army continued to attack the base area of the 385th Brigade.

And as they went deeper and deeper, the devil officers of the Third Mixed Brigade were shocked to find that the sweep in front of them did not seem to be as simple as they imagined.

With the advance to the hinterland of the 385th Brigade base area, the combat effectiveness of the troops of the Eighth Route Army encountered seemed to be getting stronger and stronger, and the equipment was becoming more and more sophisticated, and even gradually made them feel tired and shocked.

The parties are at war.

In the multi-faceted operations surrounding the Huangyadong area and the 386 Brigade base area, the Japanese army did not have a clear upper hand.

Key nodes soon converged in the 386 Brigade base area.

Inside the headquarters of the First Army of the Devils.

Yoshio Shinozuka, the commander of the devil who is in command and in charge of the overall situation, has a full view of the gradually changing situation on the military map in front of him.

There was shock and horror in his countenance.

In the area of Taihang Mountain, these damn Eighth Route Army has unknowingly grown to such a powerful point!

"General, sure enough, as you speculated, if you want to completely destroy the Huangyadong Arsenal of the Eighth Route Army and destroy the main combat force of the Eighth Route Army in the Taihang Base Area, it is only the troops that our First Army has fully mobilized this time, and I am afraid that it will not be able to do it.

If it weren't for the general's foresight, contacting the headquarters of the army stationed in Mongolia in advance, and soliciting a joint operation between the two armies, it would have been difficult to defeat these Eighth Route Army!"

Chief of Staff Kitagawa was stunned.

The strength of the Eighth Route Army once again subverted his cognition.

These were originally only behind enemy lines, and they were originally considered unfashionable in the eyes of the Great Japanese Empire, with backward equipment and scarce ammunition.

Now it has become a big problem for the Imperial Army.

"In the operations around the Huangyadong area, several mixed brigades of our army and some of the elites of the 36th Division have attracted a considerable part of the main combat forces in the Taihang base area.

The only change at the moment is the rapid southward movement of the Mongolian garrison.

According to the cavalry group of the Mongolian army, there is still a chance

By mobilizing the speed of combat troops, from time to time it will be possible to reach the northern part of the Taihang Mountains, near the defense area where the 386 Brigade is located.

A considerable part of the main force of the Eighth Route was completely pinned down in the area of Huangya Cave.

The Tuba Road of the 385th Brigade has been compressed in the base area by the 3rd Mixed Brigade.

The winter offensive launched by these damned 386 brigades of the Eighth Route Army was nearing its peak not so long ago, and it had not yet had time to withdraw its forces.

A considerable number of troops of the Eighth Route Army are even in the security zone that originally belonged to our First Army not long ago.

This is the perfect opportunity for our army to unite with the southbound troops stationed in Mongolia, and at the same time cooperate with the 3rd, 9th, and 16th mixed brigades to move north, flank from both sides, and annihilate the 386th Brigade of the Eighth Route Army in one fell swoop, and eradicate the iron triangle in the northwest of Shanxi."

Kitagawa spoke slowly, this was exactly what he and Yoshio Shinozuka had planned in the end.

Defeat the largest arsenal of the Eighth Route Army in Taihang Mountain, the Huangyadong Arsenal.

Eradicate the 129th Brigade of the 386th Division, the most powerful main brigade of the Eighth Route Army.

Destroy the damned Iron Triangle in the northwest of Jin, eliminate Kong Jie, kill Li Yunlong, and completely open the gateway to the Taihang base of the Eighth Route Army.

In one fell swoop, it recovered a large amount of land occupied by the 386th Brigade of the Eighth Route Army since its winter offensive.

"Just wait for the arrival of the troops stationed in Mongolia, unite the three mixed brigades, and attack on both sides!"

……

……

Interior of Huangya Cave.

Over the mountains, more than a dozen planes of the devils circled by, and the bombardment of the military buildings and artillery groups hidden by the Eighth Route Army in the mountains ended for the time being.

And at the moment when the mountains were remote, even the scouts of the Eighth Route Army failed to find out.

The speed of the whizzing Japanese planes seemed to have dropped a lot, and the altitude of their flight had also dropped considerably, almost flying close to the top of the mountain.

Not much.

Below the originally lonely dozen planes, a series of small black dots suddenly fell towards the mountains.

Because of the destruction of the Yamamoto Special Forces, the retired veteran members of the Yamamoto Special Forces, who hated the Eighth Route Army and gritted their teeth against Kong Jie, and the remobilized devil Nakasa Shimada Shozo, finally appeared with his Airborne Troops to destroy China.

Seizing the opportunity, an airborne operation was launched in the area of Huangya Cave.

The small black dots that gradually sprinkled down, as all the parachutes opened, more than 100 parachutes fluttered down towards the mountains, and the situation was not spectacular......
