Moreover, the nearby Imperial Army was too late to rescue, because it took time to gather troops and then come to rescue.

After pausing, Sakamoto Takaichi continued, "Teacher Commander, we actually have better choices."

"Nani? Is there a better choice?" Shinozuka Yoshio said, "What choice?"

Takashi Sakamoto pointed at the Mizukoyama model on the sand tray and said:

"Chief Commander, please see."

“Due to the obstruction of the mountain,”

"Even if you move the 75 field cannons near the top of the cliff,"

"There is no way to shoot straight shots on the target outside the mountain."

"This makes the shooting range of the 75 field cannon narrower."

"The pitch angle of Meiji 38-year-old 75mm field gun is -8 degrees to +43 degrees,"

"But due to being blocked by the water kiln mountain, its minimum shooting elevation angle cannot be less than 10 degrees!"

"Even if the Eighth Route Army raised the field cannons, the maximum elevation angle can only be increased, but not reduced."

While speaking, Takaichi Sakamoto gestured on the model with his hands and said, "Then based on this smallest angle of descent, we can calculate its minimum range."

Hearing this, everyone reacted immediately.

Yes, except for retreating to the maximum range of the 75th field cannon,

You can also get within the minimum range of the 75 field cannon, inertial thinking will kill people!

"Suga." Shinozuka Yoshio said happily, "Calculate the minimum shooting distance at a 10-degree elevation angle."

Takaichi Sakamoto smiled slightly and said, "Mr. Commander, I have calculated just now that the minimum shooting distance is 3 kilometers. As long as the Imperial Army camp is within 3 kilometers, it is absolutely safe."

"Is that true?" Shinozuka Yoshio said in surprise, "Is the campsite absolutely safe within 3 kilometers?"

"Yes." Sakamoto Takaichi said with great certainty, "It is absolutely safe within 3 kilometers."

"No." Takuya Suddenly said, "What if the Eighth Route Army forced the shooting elevation angle?"

"If the elevation angle of the field gun is forcibly raised to above 60 degrees, you can shoot a high parabola like a mortar, and you can completely shorten the minimum range to within 3 kilometers."

"This is impossible." Sakamoto Takaichi said disapprovingly.

"The Eighth Route Army's artillery position is hidden deep on the cliffs,"

"Due to the cliff opening, its elevation angle cannot exceed 60 degrees."

"Is that true?" said Takuya Mizuhara, "What if the Eighth Route Army dragged the field artillery back to the ground?"

"Haha, that's even easier." Takaichi Sakamoto said, "Just sending air force to bomb the Eighth Route Army artillery can be easily destroyed."

"this……"

Takuya Suwabata was speechless.

"Yo Xi." Shinozuka Yoshio nodded happily and said, "Order the 2nd Guard Division and Tsuda Detachment move the camp forward, and it is best not to exceed 3 kilometers from Mizukoyama."

"But not less than 2 kilometers."

"The Eighth Route Army also has mortars."

The maximum range of the mortar is approximately 2800 meters.

However, it will also be affected by the thickness and height of the water kiln mountain.

Therefore, the maximum range that can be fired is only 2 kilometers at most, so the Japanese camp is only at least 2 kilometers away from Shuiyao Mountain, which is basically safe.

With a smile, Yoshio Shinozuka said again: "So yes, this way, the Imperial Army can build a tight blockade line with a radius of 2 kilometers outside the Shuiyao Mountain, and the defense force per kilometer will exceed 3,000! What's more, the Imperial Army can use direct firepower from a distance of 2 kilometers to completely lock the Shuiyao Mountain Pass and the first-line exit."

"As soon as the Eighth Route Army was completely trapped and killed in Shuiyao Mountain."

"Haha, the Eighth Route Army is dead."

...

At the top of Shuiyao Mountain, observe the post.

Wei Xilai soon discovered an abnormality.

"Huh." Wei Xilai suddenly shouted, "Captain, the Japanese are back!"

"What? The Japanese are back?" Wei Dayong and Wang Xikui didn't care about the danger when they heard this. They quickly poked their heads over the top of the mountain and looked out the mountain. Really, the Japanese are back.

Wei Dayong said: "What's going on?"

"Yes." Wang Xikui said inexplicably, "Are the Japanese tired of living?"

At this time, Wang Ye sighed and said, "No, this time I was backfiring, I missed a little."

"I'm just a little missed?" Wei Dayong and Wang Xikui looked confused, "What do you mean?"

Wang Ye sighed: "I am only concerned about driving the Japanese to the maximum range of the 75 field cannon, but I ignore that the 75 field cannon has the minimum range in addition to its maximum range."

"Inertial thinking kills people."

"There are also people who understand the Japanese."

"So the Japanese didn't hide outside the maximum range,"

"On the contrary, it is approaching to the minimum range, which makes the Japanese encirclement of Shuiyao Mountain shrink even smaller, the unit distance becomes more powerful, and it is more difficult to break through."

“What’s worse is that both exits are locked.”

After saying this, he said, "This time I'm having a big trouble."

Wei Dayong and the other three looked at each other and their faces collapsed.

...

Wang Ye came down to tell Li Yunlong and the others about the situation.

The faces of the three team leaders also collapsed.

Li Yunlong said: "Xiao Wang, is the situation so serious?"

"It's very serious." Wang Ye said, "Now you can break through immediately, you can still break out..."

Before he finished speaking, he was immediately interrupted by Li Yunlong: "How can that be done? It has only been a week since the anti-sweeping began. How could the elders and villagers in the base be transferred?"

There are hundreds of thousands of people in the Taihang base, and it will take at least one month to transfer it.

Kong Jie also said: "Yes, if we break through at this time, the Japanese will definitely expose their anger to the elders and villagers who have no time to transfer. Then won't we harm the elders and villagers in the base?"

Wang Ye said: "But in a few days, when the Japanese repaired fortifications at the mountain pass and the first line of Tianwai, even if these two exits were completely blocked, they would not be able to break out."

Li Yunlong said: "Then we must keep it to the end."

"I agree." Kong Jie said, "We will not be able to break through the siege in one day without the transfer of the people. This is also the task assigned by the boss and the brigade commander to our three regiments."

Li Yunlong said: "Even if all three groups fight for nothing, they will do whatever they want."

Ding Wei said: "Xiao Wang, can you just climb over the cliff and break through?"

"It's ok," Wang Ye said, "but it's very dangerous, and all the heavy weapons must be thrown away."

"That's not possible." Li Yunlong said, "So many cannons, heavy machine guns, and tanks. No, no, absolutely not. If you throw away these heavy weapons, it's better to shoot me directly."

Ding Wei asked, "Is there no other way?"

"I'm afraid it's." Wang Ye said, "Once the Japanese built barracks and fortresses at Shuiyao Mountain Pass and the first line of Tianwai, even if we use tanks to launch an assault, we may not be able to break through the defense line in a short time."

He paused and said, "What's worse is that the puppet army is building a patrol road surrounding Shuiyao Mountain. Maybe he will dig a blockade ditch along the road. When the Japanese have built both the patrol road and the blockade ditch. Even if we climb over the cliffs and break through, we are afraid we won't be able to break out."

"Closed the ditch? Patrol the road?"

Li Yunlong and the other three were also shocked.

They have been dealing with the Japanese for several years.

I know the power of the combination of blocking ditches and patrolling highways.

Two years ago, their 386th Brigade lacked ammunition and was tied up by the Japanese's combination of fists. It took more than a year to pass the Zhengtai Road! This move is really amazing.

And if they cross Shuiyao Mountain to break through,

It is necessary to throw away all the heavy equipment.

Once heavy equipment is gone, the ability to attack field battles will be sharply reduced.
