The silo was discovered by the Japanese on the seventh day.
During this period, the countermeasure adopted by Neji Okamura was to resume the use of dispersed heavy artillery to bombard Yuncheng. If there was any change, it was to only bombard during the day and then evacuate at night.
It can be said that Okamura Neji has no choice.
Facing the Eighth Route Army's "special bomb", the imperial army can't just do nothing, right?
If so, does that mean admitting defeat?
No need to fight in Yuncheng?
As a countermeasure, the tactic of dispersed deployment of heavy artillery is still feasible.
Because this can not only continue the bombing of Yuncheng, but also avoid the loss of excessive artillery... Even if it is bombed by the Eighth Route Army's "special bombs", it will only lose one artillery at most.
On the other hand, Okamura Neiji also hoped to know how the Eighth Route Army avoided the Imperial Air Force's aircraft reconnaissance and launched the "special bomb"...
If the Imperial Army did not have heavy artillery to be targeted by the Eighth Route Army, the Eighth Route Army would certainly not launch "special bombs."
If the Eighth Route Army did not launch the "special bomb", it means that Okamura Neiji may never know how the Eighth Route Army launched it.
Therefore, Okamura Neiji actually used these scattered artillery pieces as a kind of bait.
Wang Xuexin had to respond to Okamura Neji's dispersion tactics.
If you think one or two guns are too few to threaten Yuncheng, what about three or four? What about seven or eight in a few days?
From this aspect, the "high fire" troops are still strategically passive.
This is mainly because the strategic goal of the "high fire" troops is to protect Yuncheng, and Yuncheng is a fixed target and very large. It is not difficult for the Japanese heavy artillery to hit it, but it is not so easy for the "high fire" troops to hit the Japanese heavy artillery.
.
In order to improve the hit rate, Wang Xuexin continued to send more troops to build launch silos during this period.
A total of eleven launch silos have been renovated in the past seven days, bringing the total to eighteen launch silos... These were all renovated using abandoned mines, but all the mines for basic energy have been used up, so the next step is to dig tunnels. At this speed
It will be much slower than before.
As the number of silos increased, another problem also emerged: a serious shortage of telephones and phone lines.
Previously, Wang Xuexin required each launch silo to be equipped with at least five telephones: one for the command center and one for each of the air defense warning posts in the four directions.
In this way, no matter which direction, as soon as a Japanese aircraft is discovered, the command center can be notified immediately, and the command center will immediately abort the launch.
Therefore, the launch silo can "not launch when there are enemy planes nearby", that is, it can be kept secret from the enemy.
There were no problems at first, but as the number of launch silos increased, telephones and telephone lines could no longer keep up... Although telephones are not very valuable items, and the Eighth Route Army captured a lot of them from the enemy, the demand for these things by the troops also increased.
It is quite large. In principle, each line of defense requires at least two telephones to complete the command. In frontline battles, relying solely on communications troops to issue orders will often miss the fighter planes. This is not sloppy at all.
So the "high fire" troops could only use the old method: using ropes to give early warning.
To put it simply, it is to dig a communication trench underground. It is best to be straight, but curved ones are also acceptable, but you need to install rollers at the corners, and then tie a hemp rope into it. When the plane comes from the sky, you can pull the hemp rope.
, the bell on the other end rang.
In principle, this is not much different from a telephone call.
Because the early warning required by the launch silo is actually very simple, that is, whether there is an aircraft or not, there is no problem in using this method of early warning.
The problem is...
These hemp ropes were bought from fellow villagers and were connected section by section.
There was no problem in connecting the sections. The soldiers connected them very carefully, but they were worried about them being interrupted in the middle.
The problem is that some of the hemp ropes come from a pig butcher in Yuncheng, whose hemp ropes are often used to tie pork...
It goes without saying what the result of this is. The rats in Shanxi are only more than ten centimeters long. They can gnaw through the hemp ropes in one or two burrows into the communication ditch.
As a result, a "high fire" was launched when the Japanese "Zero War" approached...
The person who discovered this secret was Captain Ogura, a Japanese soldier driving the "Zero War".
This "Zero War" was cruising in the air at a medium speed in order to discover the launch pads of the Eighth Route Army.
There is a reason why Okamura Neiji sent his precious "Zero War" to perform cruise search missions in the air: with the endurance of the "Zero War", it can cruise in the air for a long time without the need to frequently return to the airport to take off and land.
It actually saves fuel. On the other hand, because of its high speed, it can intercept the enemy's "special bomb" if it encounters it.
Just as Captain Ogura was observing the ground boredly, a burst of smoke suddenly rose from the lower left, and a "special bomb" flew into the sky from the bare mountain.
Captain Ogura was stunned when he saw this scene. He thought he had seen it wrong, so he forgot to chase the "special bomb" at that moment.
After thinking for a few seconds, Captain Ogura decided that he should not chase this "special bomb", but rather find out how the Eighth Route Army launched it.
Therefore, Captain Ogura immediately turned around and returned to the hill he had just passed, and then flew at low altitude close to the smoke area regardless of the danger... This is quite dangerous for pilots, especially in mountainous areas, where any protruding rock or stretched branch can be
It can destroy the Ogura machine and kill people.
Then Captain Ogura saw clearly that the smoke was coming from two caves. There were still a few people vaguely near the cave entrances, and they were busy covering the cave entrances with things to disguise themselves...
Captain Ogura hurriedly reported to the airport: "Your Majesty Colonel, there is no launcher. They are 'special bombs' launched from caves. I estimate that the entrances of these caves are camouflaged. They are opened before launch and covered after launch. So.
We just haven’t been able to find it!”
The information quickly reached Neji Okamura.
Okamura Neiji couldn't help but cursed: "Assholes, these Eighth Route Army troops are so cunning! They actually thought of this method to hide the launcher in caves and tunnels!"
Yoshio Shinozuka also felt that this problem was very difficult. He said in surprise: "Your Excellency, General, if this is the case, wouldn't our air force be unable to do anything about it?"
To be precise, it is not that there is no way, but that the efficiency is too low... Bombers can also bomb tunnels and caves, but the efficiency is almost non-existent, and even if the tunnel entrance is blown up, the Eighth Route Army can easily repair it.
But Okamura Neji didn't think so.
He stared at the map for a while, then said with a ferocious smile: "No, Mr. Shinozuka! Do you know why the Eighth Route Army camouflaged the entrance of the cave? That's because once we know the location of their tunnel, there will be a solution!"
