Gaoligong Mountain belongs to the Hengduan Mountain Range, which runs north-south.

The Nu River flows from north to south close to Gaoligong Mountain, separating Chanda 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 the South Heavenly Gate is the pass that tightly chokes the Tiandu.

Therefore, the topography of Nantianmen is like a saddle, with warped sides and concave middle.

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

Therefore, the main force of the Sichuan Army put up crane guns and mortars on the commanding heights on both sides of the saddle, and it was easy to form a fire blockade of the tree fort on the Nantianmen Pass.

The Japanese army did not fail to see this.

However, because of the obstruction of the Nu River, the national army on the east bank could not be defeated at all.

Therefore, the defensive focus of the Takeuchi United Army has always been the pass near Xingtiandu, and the Gaoligong Mountains on both sides have not been garrisoned, and in fact, they can't defend it at all.

Therefore, the main force of the Sichuan Army erected mortars with crane guns at the commanding heights on both sides, and the Takeuchi United was in trouble.

Under the fire of 18 M1917 Browning heavy machine guns and 18 60mm mortars, the assault team guarding the tree fort had not even opened fire, and the Japanese troops who launched the counterattack had already been beaten to pieces, with more than half of them killed and wounded.

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

The first wave of the Japanese counterattack was easily disintegrated by the Sichuan Army.

……

On Henglan Mountain, Yu Shi observation post.

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

Seeing that the Japanese counterattack was easily repulsed,

Zhang Lixian, He Shuguang and others followed them personally, and they all looked stupid.

"The Japanese army was repulsed? Isn't that too easy? ”

"Or else?" 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 Nantianmen, and formed a tight crossfire on the area around the tree fort. ”

"This is a trench that the Japanese army can't overcome!"

"Moat?" He Shuguang said, "Master, you seem to be saying the opposite, right?" ”

Li Bing said: "Yes, it is obviously the Takeuchi United team that is guarding according to the danger, and the South Heavenly Gate is an insurmountable moat, right?" Why is it the other way around? ”

Yu Xiaoqing was also stunned when she heard this.

yes, how did it turn the other way around?

It was obviously the Japanese army defending and the national army attacking.

Why has it now become a defense of the national army, and the Japanese army is attacking?

Can you fight a war like this? Long Wenwen and Lin Yi just cracked the fortress fortifications that Takeuchi Lianshan had painstakingly operated on the Nantianmen Gate for a year? Why didn't you think of this layer?

Yu Xiaoqing secretly regretted.

……

Inside the No. 1 sub-fort on the outskirts of the tree fort.

Mt. Takeuchi is looking through the lookout hole and observing the tree fort in the center.

Seeing that most of the infantry squad that had been engaged in the attack had been killed, and only a few dozen soldiers were left to flee back, Takeuchi was so angry that his facial muscles began to twitch violently.

"Yaga! Cunning Shina people! ”

"I actually sent troops to seize the commanding heights on both sides of the South Heavenly Gate!"

"Also build crane gun positions and mortar positions on the commanding heights on both sides of the South Heavenly Gate!"

An officer with the rank of Nakasa on his shoulders said, "Your Excellency, the Tree Fort is already extremely strong, and the difficulty of attacking head-on is already very high. ”

"Now that the Chinese army has seized the commanding heights on both sides of Nantianmen and built crane gun positions and artillery positions, it has multiplied the difficulty of recapturing the tree fort."

"Therefore, I propose to first clear the Zhina army on the Gaoligong Mountains on both sides."

"First of all, destroy the artillery and heavy machine-gun positions of China on the commanding heights on both sides."

"Hmm." Takeuchi Renshan nodded and said, "Ejima-kun, then please leave it to you." ”

"Hello!" The head of the Japanese army.

Seeing the figure of the Japanese army Nakasa go away, the haze on Takeuchi Renshan's face did not dissipate.

After pondering for a moment, Takeuchi Renshan suddenly whispered again: "Ikeda-kun! ”

An officer with the rank of Shaozo on his shoulder stepped in and said, "Captain!" ”

Takeuchi Lianshan said: "Since the Chinese army dares to send troops to seize the commanding heights on both sides of the Nantianmen, there must be other arrangements, so I'm afraid Ejima-kun's counterattack will not be too smooth." ”

"Then, we can't pin all our hopes on the Enoshima brigade."

The Japanese soldier Shao Zuo said: "So what does the wing commander mean?" ”

Takeuchi Renshan said: "The surface passage to the tree fort has been locked by the fire of the Shina army, but the tunnel hidden underground cannot be covered by the fire of the Shina army. ”

Japanese Shao Zuo said: "The wing captain means to reopen the tunnel, right?" ”

"Yes." Takeuchi Renshan Road, "Reopen the tunnel, break through the tunnel and recapture the tree fort!" ”

"The Tree Fort is the defensive support of the entire Nantianmen position, and if it is not recaptured, it will cause the imperial army to continue to lose blood until the last drop of blood is shed."

"Hello!"

……

"Camp, the devil is here!"

Bean Cake, who was lying in front of him, suddenly screamed.

Wang Yan hurriedly climbed to the edge of the cliff, raised his binoculars and looked down, and sure enough, he saw at least 500 Japanese soldiers coming out of the bunker group on the anticline of Nantianmen.

As soon as they left the bunker, they split into two groups.

More than 200 Japanese soldiers pounced on the south of Nantianmen.

The other more than 200 Japanese soldiers swooped straight in the direction of Wang Yan and them.

More than 200 Japanese troops, that is, an infantry squadron, under normal circumstances, are enough to defeat a main regiment of the national army! Therefore, the Japanese army still attached great importance to the Sichuan Army.

It's just that this time, the Japanese army is doomed to miscalculate.

At that moment, Wang Yan slid down from the top of the cliff and said loudly: "Reconnaissance company, assemble!" ”

More than 100 old cannon fodder from the reconnaissance company quickly ran to Wang Yan to assemble with the front team.

After reporting the number, Wang Yan took the reconnaissance company forward a hundred meters and lurked in the jungle.

Wang Yan divided the more than 100 people of the reconnaissance company into three groups, occupying the directions of 4 o'clock, 8 o'clock, and 12 o'clock respectively, forming an inverted triangle ambush formation.

After a few minutes, the Japanese army's elite group silently entered the ambush circle.

Wang Yan was unmoved, his target was the main force of the Japanese infantry squadron, and a mere group of top soldiers was not in his eyes at all.

The vigilance of the Japanese army's elite group is not high, but they are ignorant of the cannon fodder of the Sichuan Army that is less than twenty meters away, of course, this cannot be blamed on them, in the jungle environment, unless the enemy takes the initiative to expose, otherwise, even if it is stepped on others, it is difficult to find the other party.
