The kid Takeo on the mountain was also very lucky. He had just descended from the vast underground space to the previous tunnel when he heard a strange sound. Without thinking about it, the kid immediately put out the torch and walked back.
He shrunk and quietly hid in the drainage ditch about one meter high behind him.
Not long after Takeo hid in the drainage ditch on the mountain, a hole opened in the wall on one side of the corridor. Then, the hole became bigger and bigger, but it turned out that there was another passage there, but
It had been bricked up by the Chinese before, and the surface was smeared with mud to camouflage it, so the Japanese search team did not find it.
But Takeo on the mountain hid in the drainage ditch and saw the darkness from the light, but he could really see it.
Immediately afterwards, a dozen armed men filed out of the opened passage. What was surprising was that these armed men were also wearing Japanese protective clothing and gas masks. But Takeo Yamayama was very convinced that these dozen
The armed personnel are definitely not Japanese troops, because there is no way the Japanese troops can come out from here.
Needless to say, these dozen armed men must be Chinese soldiers.
After these dozen Chinese soldiers came out, they immediately occupied both ends of the corridor. Two of them even walked to the entrance of the drainage channel and squatted down. However, they frightened Takeo on the mountain half to death. Takeo on the mountain hurriedly moved back silently.
He took a few steps back, and when he looked again, he saw that these dozen Chinese soldiers were already aiming their guns at the wooden ladder.
Immediately afterwards, fierce gunshots rang out in the underground space above.
Then, Japanese soldiers came down the ladder, but were shot one by one by the Chinese soldiers who had been waiting at the bottom. Occasionally, those who survived the shot were ruthlessly stabbed to death by the Chinese soldiers with bayonets. In less than a moment, the soldiers above
The gunfire stopped, and then a Chinese soldier climbed down the ladder and said something to the dozen or so Chinese soldiers below. The dozen or so Chinese soldiers below began to clean the battlefield, carrying weapons, ammunition and
The bodies of the Japanese soldiers were temporarily left.
Taking advantage of the absence of the Chinese soldiers, Yamatakeo rushed out of the drainage channel, ran back along the corridor he came from, and ran back to the ground in one breath.
On the ground, Akira Muto was angry because he couldn't get through the phone call.
Seeing Takeo climbing out of the entrance to the tomb, Akira Muto immediately rushed forward, grabbed him up, and asked, "What happened down there? Why didn't Matsui answer the phone?"
"Sir, it's all over." Yamatakeo took a breath and told everything he saw.
After Muto Akira heard this, his heart suddenly sank, and then he quickly came to Kawaguchi Heiji and made a report.
After listening to the report, Kawaguchi Heiji's thick eyebrows frowned instantly. This tunnel battle was far more difficult to crack than he imagined.
Kawaguchi Heiji said solemnly: "Judging from the fact that the search team was surrounded and annihilated, it seems that it is not feasible to launch a direct attack deep into the tunnel. Not to mention the casualties, the efficiency is too low. The maximum number of troops invested each time is
A small team, how long will this mopping up operation last before it ends?"
"Hai." Muto Zhang nodded, "I also think that direct attack is not a good idea."
"Then." Kawaguchi Heiji asked again, "Besides direct attack, is there any other way?"
Muto Akira was silent. He couldn't think of any good solution. This matter was indeed difficult.
"Is there really no other way?" Kawaguchi Heiji frowned, as if talking to himself, and seemed to be asking the staff around him, but no one dared to answer, because for them
, Tunnel warfare is a brand new way of combat, they have never learned this at Army University.
At this moment, Oluhara Junsi said: "Your Excellency, Commander, there may be another way."
"What can I do?" Kawaguchi Heiji's eyes immediately fell on Ogahara Junsi.
Xiaoluyuan said: "Your Excellency, Commander, according to the intelligence, there are five to six thousand residents in Meizhen Town. If residents of surrounding villages are added, the number will be even larger. From the current point of view, these people should all be hiding in
In the tunnel, with so many people concentrated in the tunnel, eating, drinking and defecating every day must be a problem."
Kawaguchi Heiji looked sharply and said, "You mean, find their drainage and smoke vents?"
Five to six thousand or even tens of thousands of people live together in tunnels. They have to eat, drink, poop, and defecate every day. The excrement produced by defecating and defecating needs to be excreted through the drainage system. To eat and drink, they need to boil water for cooking.
Boiling water for cooking will produce cooking smoke, which needs to be discharged into the air through a smoke exhaust vent, otherwise it will accumulate in the tunnel and kill people.
As long as you find the drain outlet or smoke exhaust outlet, the next thing will be simple.
Find the drainage outlet and then block it, and then introduce backflow from the tunnel entrance. The tunnel will be flooded. The Chinese soldiers and Chinese people hiding in the tunnel will undoubtedly die. If they don't want to be drowned, they can only
Obediently returned to the ground and had an upright decisive battle with the Japanese army.
Once you find the smoke outlet, it will be easier. You only need to pour the poisonous gas in through the smoke outlet. The Chinese soldiers and Chinese people hiding in the tunnel will immediately be poisoned and die in large numbers. Then the only thing left is to send a team.
Chemical defense troops entered the tunnel to conduct autopsies on Chinese soldiers and Chinese civilians.
Oluhara Junsi said: "Your Excellency, Commander, it may be difficult to find the drainage outlet, because the water only needs to provide a diagonal downward channel, and it will flow forward. The Chinese can even dig a tunnel directly connected to the town.
It is outside the Meihe River, so it is difficult for us to determine the specific location of the drainage outlet."
Kawaguchi Heiji nodded with deep approval and motioned for Ogawara Junsi to continue.
Oluhara Junsi added: "But the smoke exhaust port is not the case, because cooking smoke is a kind of heat flow. The heat flow flows very slowly in the flat channel and will not flow down. The only way is to build the smoke exhaust flue upward and high enough.
, cooking smoke can be smoothly discharged into the atmosphere, so when repairing stoves in rural areas, the smoke exhaust vents are usually built on the roof to increase the vertical drop of the exhaust duct and increase the intensity of smoke exhaust."
Kawaguchi Heiji nodded and said: "So?"
Oluhara Junsi added: "So, cooking smoke cannot be emitted in a centralized manner like excrement. The emission of excrement can be concentrated in more than a dozen villages, but cooking smoke is impossible. Cooking smoke can only be emitted nearby, and the smoke can be emitted nearby."
The outlet must be quite high above the ground, otherwise it will definitely lead to poor smoke exhaust."
"Yoshi." Kawaguchi Heiji nodded happily, turned around and shouted, "Muto-san?"
"Hai." Muto Akira stepped forward and responded loudly, "What are your orders?"
Kawaguchi Heiji said: "Immediately send out a search team to search the nearby terrain 24 hours a day. If smoke is found somewhere, report it immediately."
"Hai." Muto Sho nodded, followed the order and turned around.
Within a moment, Muto Akira sent out several search teams to conduct comprehensive surveillance of the fields for miles around Xiaoli Village. However, what made Muto Akira extremely disappointed was that until dawn the next day, until Kawaguchi
Heiji has returned to the headquarters in Meizhen, and the search teams sent out have found nothing.
Muto Akira, Oluhara and Kawaguchi never thought that the Dameishan Independent Group had already solved the problem of smoke exhaust.
The solution of the Dameishan Independent Group is actually very simple. It is worthless to say it. According to physics, it is impossible for hot air to flow downward, and the flow rate in a gentle channel is also very slow, so it is impossible to emit concentrated smoke. However,
Just because cooking smoke cannot be emitted in a centralized manner does not mean that cooking cannot be done in a centralized manner!
The solution for the Dameishan Independent Group is to concentrate on making rice.
Choose a hidden mountain col in the mountains, first concentrate on cooking, and then use manpower to deliver the cooked meals into the tunnel, and then deliver them to every village through underground transportation lines extending in all directions, and deliver them to every soldier and every citizen.
Here, this cleverly solves the problem of emitting cooking smoke and eliminates the risk of Japanese attacks from the smoke outlet.
As for the smoke emitted in the mountains, it is impossible for the Japanese to detect it because of the mountains' obstruction.
What's more, even if it is discovered, there is no problem. At worst, we can continue to make food in another place.
The Muto Brigade's surveillance in Xiaoli Village found nothing, but the next night, the search team sent to Yangcun was once again attacked by the squadron. Just like in Xiaoli Village, the squadron also used the tunnel to appear quietly.
, and then while the search team was resting, they suddenly launched an attack.
Moreover, Yangcun's search team was even worse than Xiaolizhuang.
Xiaolizhuang's search team managed to escape with more than a dozen cavalrymen, but Yangcun's search team was collectively shattered, with no one left alive.
After receiving the news, Kawaguchi Heiji was so angry that he dropped his kettle and immediately ordered that all the search teams sent out should be withdrawn immediately. Muto's independent brigade was also withdrawn at the same time.
Although he was angry inside, Kawaguchi Heiji did not lose his mind.
By this time, Kawaguchi Heiji had clearly realized that facing the squadron's tunnel warfare, the Japanese army did not have many options, and could even be said to be helpless. The only countermeasure he could think of now was to mobilize engineers and carry out the operation in the vast Dameishan Basin.
The blasting operation blew up all the Chinese tunnels.
But this is just thinking about it, because it is not easy to carry out blasting operations. First, you have to determine the specific location of the tunnel. Second, you have to ensure the safety of the engineers. The last and most difficult point is that the cost of digging a tunnel is even higher than that of blasting a tunnel.
To make it cheaper, this is completely a war of attrition that outweighs the gains and losses.
Although he has not yet reached the final step, Kawaguchi Heiji can already foresee the final result of this sweep. If a miracle does not occur, this sweep operation will probably end in failure. Now Kawaguchi Heiji feels extremely struggling.
One question is, should we withdraw our troops immediately?
[515 is coming soon, and I hope to continue to hit the 515 red envelope list. On May 15th, the red envelope rain will be able to reward readers and promote the works. It is also love, and I will definitely update it!]
