The pig-killing mouth is a narrow and long canyon running north and south.

The road from Datong to Taiyuan passes through the canyon.

According to legend, Duke Wen of Jin, Chong'er, once hunted a wild boar here when he escaped during the rebellion of Li Ji, leaving behind a unique place name such as Pig Killing Mouth.

To put it bluntly, this terrain is a ditch.

The most common terrain in northwestern Shanxi, the uplifting loess platform is washed out from the ditch by years of rain, and over time it becomes roads.

One of the ditches has built a road.

This highway is Tongpu Highway.

Such a terrain has no connection with the word "steep".

Even if you don’t pass through the canyon, you can still climb up the ridges on both sides along the slopes, and you can even ride a horse directly on some areas.

The vanguard squadron of the 4th Japanese cavalry brigade,

A total of about 130 cavalrymen slowly entered the canyon in four columns.

Seeing that the entire cavalry squadron had entered the canyon, Qian Bojun immediately raised his Browning pistol and pulled the trigger at the cavalry closest to him.

Just a sound of the trumpet,

The Japanese cavalry fell off the horse.

The next second, the soldiers of the Jinsui army who were ambushing the loess on both sides of the canyon opened fire, pouring dense rain of bullets onto the Japanese cavalry in the canyon.

More than 130 Japanese devils were caught off guard and fell off the horse in an instant.

In a blink of an eye, more than 130 Japanese cavalrymen died to only a few dozen, but the remaining dozens of Japanese cavalrymen finally rushed out of the canyon and fled back to the mouth of the pig.

Seeing this, Zhang Fugui said in surprise: "Battery Commander, what's wrong with the Japanese army?"

"Yes, is it because the Japanese army has become weaker, or is it because our Jinsui army has become stronger?" Qian Bojun was also a little confused. When he was fighting with the Japanese army in Xinkou and Taiyuan in Xinkou, the performance of the Japanese army was not as bad as today.

Even if they were ambushed, the Japanese army would not collapse so quickly, right?

Didn’t it mean that the Japanese cavalry were all elite? The elites were about to collapse?

...

Two kilometers outside the pig's mouth.

Hashimoto Toshio Mama came to Kojima Yoshizo and said with a flattering look: "Brig Commander, you are really a clever plan. There are indeed Chinese ambushers in the canyon in front."

Yoshizo Kojima said proudly: "Sun Tzu said that war is a strange way. In a dangerous place like the canyon ahead, it is not surprising that there will be Chinese ambushers at all, but it is strange that there is no talent."

Hearing this, Lunbu Yuki showed a constipation look on his face.

This kind of terrain can also be linked to the word "dangerous" and is also a perfect match.

And how many times have you "discovered" the ambushed forces along the way south?

If it weren't for the fact that there were a lot of ambushes you "discovered", it would probably have passed by Taiyuan.

It is said that ugly people are often used to make trouble, idiots like to show off, the ancients were really honest and did not bully me, and the brigade commander was a real idiot.

The Orange Tree of Lingbu lowered the telescope and said, "From the fire density exposed on both sides of the canyon, the Chinese ambush at best is only four or five hundred people, and there are more than a dozen light machine guns."

Hashimoto said sneered: "That little force is not enough to even put our teeth into pieces."

"Hashimoto, don't be careless." Lunbe Yuki shook his hand and said, "This is just the exposed Chinese army and firepower points, and perhaps the hidden Chinese army and firepower."

"Mr. Lingbu, I'm afraid you're too cautious."

Hashimoto said with a smile: "Even if the entire Chinese army in northwestern Shanxi has come here, how many troops can it have? Can it withstand a full-scale attack from our 4th Cavalry Brigade?"

Between the two people argued, the forward squadron had already lost and fled back.

However, a full squadron of more than 130 people only came back more than 50 cavalry.

Hashimoto said contemptuously: "These Goryeo sticks are really useless."

"These guys are really useless." The view of Ryube Yoshiki this time was exactly the same as that of Hashimoto Tsuyoshi. "Faced with the Chinese army, he could even collapse at one touch."

"It really lost all the face of the Japanese Imperial Army and even more the face of the cavalry."

Hashimoto said: "Brig Commander, I suggest that these wastes should not wear the Imperial Army uniforms in the future. Their performance is really not worthy of this uniform."

"I think that this group of Korean waste can still act as cannon fodder and make the way for the imperial army, I will reluctantly allow them to wear the imperial army uniform." Kojima Yoshizo waved his hand and said, "Hashimoto."

Hashimoto Tsuyoshi immediately stepped forward, paused and asked, "What are the instructions of the brigade commander?"

Yoshizo Kojima raised his wrist and looked at his hand, saying, "It's 1:30 pm now. I'll give you half an hour. The passage must be opened before two o'clock. In this way, we may be able to reach Taiyuan before dark, otherwise we will only be able to camp in the wind and snow tonight."

"Hayi!" Hashimoto's head was slammed.

...

Kill pig's mouth.

Qian Bojun and Zhang Fugui have arrived at the front of the ridge.

There are two defense lines on the front of the pig's mouth, one is located on the ridge line and the other is two soil buns outside the mouth.

Qian Bojun set up a reinforced platoon of troops outside the two landbags outside the mouth, and two civilian-type 24 heavy machine guns.

Qian Bojun's idea is still very good. The two soil buns outside the mouth can obtain firepower protection from the main position of the earth ridge and also provide protection to the main position of the earth ridge behind him. In fact, it is a horn-like momentum.

Since ancient times, the formation of a horn has been the core essence of defensive operations.

Seeing that the Japanese army had put in about two small teams of cavalry and launched an attack on the two landblocks outside the pig's mouth, Qian Bojun and Zhang Fugui did not take it seriously.

The first wave of fire exchange just now gave the two great confidence.

If the Japanese army had only such a little combat power, then one battalion could block the entire cavalry brigade!

Qian Bojun even further imagined that when their 1st battalion fought with the 4th Japanese Cavalry Brigade, if Chu Yunfei led the main force of the 358th Regiment to surround the two wings, he might be able to wipe out the 4th Cavalry Brigade.

Thinking of this, Qian Bojun felt a little excited. If this is the case, then their 358th Regiment will become famous.

Although Chu Yunfei would soar into the sky, even Qian Bojun would probably follow the crowd and get a team leader.

In a blink of an eye, the Japanese cavalry approached within 100 meters. The Jinsui army guarding two landbags opened fire at the same time. The two 24-heavy tribute guns of the civilians who were on the commanding heights also opened fire violently.

A dense rain of bullets poured onto the heads of the Japanese cavalry again.

However, this time, the situation that Qian Bojun and Zhang Fugui were expected did not occur.

After being attacked by the Jinsui Army's bullet rains, the Japanese who were involved in the attack did not collapse at all, but instead raised their guns to fight back while running.

Opportunities are actually equal for both parties.

The soldiers of the Jinsui Army were unable to lock in the targets moving at high speed, but it was difficult for the Japanese to aim on the horses running at high speed, so at this time they could only rely on the training of the soldiers on both sides and the sense of guns.

In this regard, the Japanese cavalry showed a huge advantage of overcoming.

Although the Jinsui Army built fortifications in advance, the area of ​​bullets exposed to the enemy's guns was much smaller than that of the Japanese army, the casualties of the Jinsui Army during the firefight were much greater than that of the Japanese army.

The Jinsui Army can be said to have been completely suppressed by the Japanese army.

Even the two Min-24 heavy machine guns didn't last long.

Because the machine gunners of the Jinsui Army made the most fatal mistake.

They foolishly built the firepower point at the highest point of the defensive position.

This is as simple as shooting a target for the Japanese grenadiers.

Four Japanese cavalrymen quickly turned over and dismounted, hid behind the cavalry in front and raised the grenade launcher. They used only four grenades to easily destroy the two civilian 24-heavy machine guns of the Jinsui Army.

Although the number of troops guarding the two landbags was superior, the marksmanship was not as good as that of the Japanese army. Now even the two heavy machine guns that were the last to rely on were destroyed, and the psychological defense line collapsed instantly.

I don’t know who took the lead first, dozens of people turned around and ran away.

This run is even more complete. How can a human leg run beyond a horse's four legs?

The Japanese cavalry soon caught up, first carried the horse rifle back on their shoulders, then pulled out the saber and slashed. The soldiers of the Jinsui Army who were running wildly were killed on the ground in rows of heads.

Seeing this tragic scene, Qian Bojun and Zhang Fugui were so angry that they cursed.

Chu Yunfei saw it on the observation post in the distance, and his face turned green.

To be embarrassed, I'm so sad, Chu Yunfei has decided to arrest the two platoon leaders and shoot them. What soldiers are you carrying? There is no bloodiness of Chinese soldiers at all!

At this moment, an attack plane whizzed past the pig's mouth.

Chu Yunfei's face was even more ugly. The blocking battle of killing pig mouth seemed to be more difficult than he expected. Qian Bojun's 1st battalion might not last for two hours.

...

In Taiyuan, the 1st Army Headquarters.

Yoshio Iwamatsu just walked into the first floor combat hall.

Communications Section Chief Yasushi Inoue came forward to report: "Commander, the aviation scout sent back a telegram, and the 4th Cavalry Brigade was blocked by the Jinsui Army at the Pig Killing Mouth."

"Kill the Pig's Mouth?" Yoshio Iwamatsu turned his eyes to the map.

The combat division chief Takaichi Sakamoto quickly found the pig killing mouth on the map.

"Say it." Yoshio Iwamatsu nodded happily and said, "The pig's mouth is only 30 kilometers away from Taiyuan. The 9th Brigade will march for four hours to arrive at the battlefield!"
