I fought guerrilla warfare in the Yimeng Mountains during the Anti-Japanese War

Faced with this kind of hedgehog-type defense, the commandos could only lie on high ground and listen to the movement. While listening to the movement, Chen Feng was judging the situation on the scene. The National Army was not without artillery. They had engaged in many artillery battles with the Japanese army in the morning. However, the artillery shells fired in the afternoon gradually became sparse, probably because many of them were destroyed by the Japanese heavy artillery.

Reverse slope, three words suddenly popped up in Chen Feng's mind. As long as the Kuomintang's artillery blocked the main attack points of the Japanese army, the battle would be much easier. By using the reverse slope, the Kuomintang's artillery could be protected and the Japanese artillery shells could be consumed, achieving multiple goals at one stroke. There was no need to worry about the Japanese army stealing their skills. The Kuomintang's artillery could not reach the Japanese artillery positions, and there was no point in them using it. After all, in the Chinese Anti-Japanese War, there were not many battles in which the Kuomintang could happily bombard. Besides, this thing was originally invented by them in the Pacific battlefield. At that time, it was a way to avoid the huge artillery of the US warships. Later, our army took this combat method to the extreme in the South War and the Korean battlefield.

He acted right away. At eight o'clock, Chen Feng asked the team members to be on alert immediately. After he adjusted the radio, he sent a message to Li Yunyan.

At the Fifth War Zone Headquarters in Xuzhou, Li Yunyan was monitoring the radio in the communications room. Li Yunyan started monitoring at 7:50. Even though the fighting on the front was fierce and messages were flying all over the place, the commander-in-chief emphasized many times that they had to keep the two eight o'clock times. At exactly eight o'clock, Li Yunyan suddenly monitored a special signal.

Li Yunyan took the receiver and took notes while listening. It took him half an hour to record a telegram. It must be something big. He returned to the confidential room, took out the secret message book and quickly translated it. The content slowly appeared on the paper. The more Li Yunyan read, the more shocked he became, and the more surprised he became. After completing the translation, he calibrated it again, put it in an envelope, sealed it, and ran to the military intelligence simulation room.

Li Zongren was discussing the war on the front line with his subordinates. The Yunnan Army suffered too many casualties in one day. If it were normal times, such losses should have been withdrawn and replenished, but it was not possible now. If an army could not hold out for less than a day, it would give the troops behind it a psychological impression that the Japanese army was invincible.

Discussions in the war situation simulation room were in full swing. We still had to find a way to reduce the losses of the defensive forces, otherwise even with more than 200,000 people, they would not be able to hold out for long.

Suddenly, a report came from outside:

"Reporting to the commander, No. 5 sent a top-secret telegram."

"Come in".

Because they were in the Fifth War Zone, the Lone Wolf Commando was given the code name Five, which made it easier to mention them in public, but no more than three people knew this code name.

Li Zongren was somewhat expectant. The war was in full swing and the Lone Wolf Commando suddenly sent out a message. It must be something very important. Maybe it was a strategy to restrain the Japanese army.

Li Zongren checked the envelope, tore it open, took out the message and began to read it. His expression was exactly the same as Li Yunyan's. The more he read, the more frightened and excited he became. It took him more than ten minutes to fully understand the meaning of the message:

"Genius, an absolute genius!"

Turning to look at Li Yunyan:

"Who has had access to this telegram?"

"Reporting to the Commander-in-Chief, I am solely responsible for this telegram and it has not been accessed by anyone else."

"Okay, go down! I won't emphasize the confidentiality."

"Yes".

A group of staff officers looked at Li Zongren. It seemed like good news!

Li Zongren seemed not to notice the expectant looks of his colleagues and burned the telegram himself. None of his colleagues dared to inquire about it, as this must be top secret information.

Li Zongren was somewhat hesitant. The matter was too serious. If it was revealed to the subordinate units, it might be leaked soon. Although Leng Qiang said that it would not be a big deal even if the Japanese knew about it, Li Zongren had to consider it carefully.

After everyone dispersed and left, Li Zongren slowly paced in the simulation room. After thinking it over, he still felt that the losses on the front line were too great and the artillery could not play its due role at all. So, let's use it! Judging from the current situation, it is unlikely that we will be able to fight against the Japanese artillery in the future.

Li Zongren answered Lu Han's call. This matter had to be discussed face to face.

On the morning of April 12, the Japanese army began shelling. The entire front-line position of the National Army was under continuous artillery fire. The shelling lasted until eight o'clock. The bombing squadron arrived, dived, opened the ammunition magazine, and the bombs poured down on the National Army's positions like hail. With the artillery preparation, Lu Han withdrew two-thirds of the defenders on the defense line, and the other one-third hid in the anti-artillery caves.

After an hour of bombing, the entire frontline of the National Army was in ruins. The Japanese army began to charge, with tanks leading the way and groups of devils following behind, pressing towards the front line.

At the 300-meter line, the National Army began to fire sideways at the infantry behind the tanks. At the 200-meter line, the tanks began to accelerate and the infantry also rushed to the front of the tanks, protecting the safety of the tanks while charging.

There was heavy gunfire from the National Army's positions, and the Japanese began to suffer casualties. Suddenly, there was a sharp sound of breaking through the air, and a shell had arrived. The Japanese instantly fell to the ground, waiting for the shelling to pass. From yesterday afternoon, the National Army's artillery positions had been hit by heavy artillery from the Japanese, and the shells had become much sparser. They could only fire for a maximum of three minutes, otherwise their own heavy artillery and mountain artillery would destroy them.

The Kuomintang's positions were still firing, and the Japanese had no choice but to fire back at them. Three minutes later, the shelling had not stopped, and the charging Japanese could only lie down and take the blame. Within a few minutes, a large number of soldiers were killed or injured because their formation was too dense.

Five minutes later, the heavy artillery opened fire. After a round of test firing, the shooting parameters were adjusted and the shells flew towards the Kuomintang artillery positions for free. Although the Kuomintang artillery was still firing, their legs were trembling. They didn't know whether the tactics of their superiors would work. Once the shells fell, not a single drop of debris would be left on the position.

The shells came flying, passing over their heads with sharp whistles and dazzling lights, and all exploded at the bottom of the slope. Although the pressure brought by the explosions of the 150mm howitzers and 75mm mountain guns was very strong, the artillery of the 60th Army was still extremely excited. It was useful, really useful. They had no time to pay attention to the explosions in the distance, and the mountain guns and mortars continued to fire.

The commander of the Japanese artillery position couldn't understand why the other side was still firing after they had clearly blown up the Nationalist artillery position. He had no choice but to continue ordering the bombardment. For a while, artillery shells were fired back and forth between the two sides, but the Nationalist Army bombed the Japanese stormtroopers and tanks, while the Japanese bombed the open space behind the Nationalist artillery position.

The Japs retreated. Twenty minutes of shelling had caused them heavy losses. The KMT artillery position observer signaled with a flag and the artillery stopped shelling. The artillery position was instantly filled with cheers and countless artillerymen hugged each other to celebrate this rare victory.

Kenji Doihara and Seishirō Sakagami were both very confused. They could have taken the position today, but something went wrong that they couldn't understand. Why couldn't the artillery destroy the opposing artillery position?

Could it be that the other side has set up an artillery fortress behind us? That's impossible. Because of the large number of spies, the Japanese army didn't have a comprehensive understanding of the National Army's front line, but they knew it roughly. This situation didn't happen yesterday. It is absolutely impossible for them to set up an artillery fortress in one night.

After communicating, the two were both very confused about this matter, but the attack could not be stopped. All eyes were now on the Taierzhuang battlefield. They could only order the attacking troops to disperse their formation and attack the National Army's defense line. However, this would make it easier for the National Army to defeat them.
