Check in from the bright sword

As if they heard Wang Yan’s call, the Japanese army on Nantianmen really responded. Along with the babbling shouts, about a small group of Japanese infantry came out of the sub-forts, trenches and traffic trenches around the tree fort With a shining bayonet, they rushed towards the tree castle in the center like a tide.

Wang Yan immediately shouted: "Fire!"

Six 1917-type Browning heavy machine guns lined up behind him opened fire at the same time.

In an instant, six dazzling tongues of flame were whipped towards Nantianmen like the whip of death.

Almost at the same time, six 60-caliber mortars on the reverse slope behind them also fired at the same time, smashing rows of shells towards the tree fort at Nantianmen.

Almost at the same time, the two machine gun companies of the 2nd and 3rd Battalions of the Sichuan Army, which entered the left side of Gaoligong Mountain, also opened fire.

Covered by artillery fire from 18 191-caliber mortars, the [-]-meter radius of the tree fort immediately became an insurmountable natural moat.

Chapter 67 Insurmountable

Gaoligong Mountain belongs to the Hengduan Mountains and runs north-south.

Nujiang flows close to Gaoligong Mountain from north to south, separating Zenda on the east bank from Longling and Tengchong on the west bank, and Xingtiandu is the only traffic artery connecting the east and west banks.

And Nantianmen is the pass that strangles Xingtiandu.

Therefore, the terrain of Nantianmen is like a saddle, with upturned sides and a concave middle.

The hilltop tree fort, which served as the defensive support of the Takeuchi Alliance, was in the middle of the saddle.

Therefore, the main force of the Sichuan Army set up crane machine guns and mortars on the commanding heights on both sides of the saddle, which could easily form a fire blockade on the tree fort on the Nantianmen pass.

The Japanese army did not fail to see this.

But because of the barrier of the Nujiang River, the east bank can't fight at all.

Therefore, the defensive focus of the Zhunei United Team was always the pass near Xingtiandu, while the Gaoligong Mountains on both sides were not stationed separately, and in fact they could not defend at all.

Therefore, the main force of the Sichuan Army set up mortars with machine guns on the commanding heights on both sides, and the Takeuchi United Team will be in trouble.

Covered by the firepower of 18 1917-style Browning heavy machine guns and 18 60-caliber mortars, the commandos guarding the tree fort had not even opened fire, and the Japanese army who launched the counterattack had been beaten to pieces. More than half were killed or injured.

After paying more than half of the casualties, the remaining 20 Japanese soldiers finally fled back in a hurry.

The Japanese army's first counterattack was easily disintegrated by the Sichuan Army.

……

On Henglan Mountain, Master Yu's observation post.

Because Nantianmen is on the pass, from the observation post on Henglan Mountain, you can clearly see the whole battle situation around Nantianmen Tree Fort.

Seeing that the Japanese counterattack was easily repelled,

Zhang Lixian, He Shuguang and other followers were all dumbfounded.

"The Japanese army was repulsed now? Isn't this too easy?"

"Otherwise?" Yu Xiaoqing said coldly, "The main force of the Sichuan Army has already built heavy machine gun arrays and artillery positions on the commanding heights on both sides of the Nantian Gate, and formed a tight crossfire on the area around the tree fort. Before the heavy machine guns and artillery on the side commanding heights, no matter how many Japanese troops come, they will die."

"This is a natural moat that the Japanese army has no way to cross!"

"Sky moat?" He Shuguang said, "Master, you seem to be saying the wrong thing?"

Li Bingdao: "That's right. It's obviously the Zhunei United team that is defending according to the danger. The Nantian Gate is the insurmountable natural moat, right? Why is it actually the other way around now?"

Yu Xiaoqing was also stunned when she heard the words.

Yes, why is it the other way around?

It is obvious that the Japanese army is defending and attacking.

Why is it now on the defensive, and the Japanese are attacking?

Can you still fight like this?Long Wenwen and Lin Yi cracked the fortification that Takeuchi Lianshan had worked hard on Nantianmen for a year with just such tinkering?Why didn't I think of this level?

Yu Xiaoqing was deeply regretful.

……

Inside the No. [-] Fort outside the Tree Fort.

Takeuchi Lianshan is observing the tree fort in the center through the lookout hole.

Seeing that most of the infantry squad that went into the attack was killed, and only a few dozen soldiers escaped back, Zhu Nei Lianshan was so angry that his facial muscles began to twitch violently.

"Baga! Cunning Chinese people!"

"Sent troops to seize the commanding heights on both sides of Nantianmen!"

"We also built crane gun positions and mortar positions on the commanding heights on both sides of Nantianmen!"

An officer with the rank of Lieutenant Commander on his shoulder said: "Your Excellency, the tree fort is already extremely strong, and the difficulty of a frontal assault is already very high."

"Now that the Chinese army has seized the commanding heights on both sides of the Nantian Gate and built positions for lifting machine guns and artillery, it has doubled the difficulty of retaking the tree fort."

"Therefore, I suggest first clearing out the Chinese army on Gaoligong Mountain on both sides."

"First destroy the Chinese artillery and heavy machine gun positions on the commanding heights on both sides."

"En." Takeuchi Lianshan nodded and said, "Jiandao-kun, then I'll leave it to you."

"Hayi!" Zhong Zorton nodded in the Japanese army.

Watching the figure of the Japanese lieutenant commander go away, the haze on Takeuchi Lianshan's face did not dissipate.

After pondering for a moment, Takeuchi Lianshan suddenly shouted again: "Ikeda-kun!"

An officer with the rank of Major on his shoulders entered the room in response, and said with a pause, "Commander!"

Takeuchi Lianshan said: "Since the Chinese army dared to send troops to seize the commanding heights on both sides of the Nantian Gate, there must be other arrangements, so Jiang Dao-kun's counterattack may not be too smooth."

"Then, we can't pin all our hopes on Jiangdao Brigade."

The Japanese army major said: "Then what does the captain mean?"

Takeuchi Lianshan said: "The surface passage leading to the tree castle has been blocked by the firepower of the Chinese army, but the hidden underground tunnel cannot be covered by the firepower of the Chinese army."

The Japanese army commander said: "The captain means to reopen the tunnel, right?"

"Yes." Takeuchi Lianshan said, "Open the tunnel again, break in from the tunnel and take back the tree fort!"

"The tree fort is the defensive support of the entire Nantianmen position. If it is not taken back, the imperial army will continue to lose blood until the last drop of blood is shed."
