Cat ear piercing is actually not a high-tech, it is very simple, just dig a small hole long enough for a person to hide in the back side of the trench, because it is shaped like a cat's ear, so it is called "cat ear piercing".

Don't look at it as a small hole, but it's not small.

The first is against the shells...... As you can imagine, there are not many shells that could have been smashed directly into the trenches, and even if these shells could explode in the trenches, they would not be able to hurt the soldiers hiding in the cat's ear holes, unless these shells directly hit the cat's ear holes.

The second is the airplanes in the air, even if the planes follow the direction of the trenches and pour bullets into the trenches, they will not be able to hit the people who are cowering on the side walls.

In the same way, with cat's ear piercing, the Japanese grenade will drop pieces of grenades, and the casualties will be much smaller.

However, in theory, this is true, but in reality it is not a happy thing to hide in a cat's ear hole...... Outside, there was a whistling and explosion, and the air was filled with the heat and smell of gunpowder from the explosion of the shells, while he hid in a small and elevated space, feeling the vibration of the explosion of the shells around him, and the mud falling overhead, and he didn't even have room to move.

This was the first time that Zhang Chi was caught in the fire preparation of the Japanese army.

Looking back on the past, Zhang Chi felt that he was too lucky to fight so many battles...... For example, the Tonggu Breakout, such as the Wajie Iron Bridge, and then the Ren'an Qiang, faced a lot of devils in every battle, but none of them were bombarded by Japanese aircraft and artillery, and now he finally felt it.

Hiding in this cat's ear hole, Zhang Chi even had a strong urge to rush out, because he didn't feel that he was safe in this rudimentary fortification, and it could be blown up by a cannonball at any time and bury itself in it.

But at the same time, Zhang Chi knew that he couldn't go out, because if it wasn't safe here, it wouldn't be safe outside...... At least there's no shrapnel flying around.

Later, Zhang Chi learned that the soldiers really couldn't help but run out...... Many of the Engineer Corps were new recruits, who had no such experience and no training, and a few of them were so frightened that they ran around outside, only to be never found again, and they disappeared without even a body.

It's like a century long, and the devil's artillery fire has finally slowed down.

But before Zhang Chi had time to breathe a sigh of relief, he heard a piercing whistle outside, and after the whistle was the devil's hoarse voice: "Give me all out, prepare for battle, the devil is coming!" ”

Zhang Chi almost crawled out of the mound, because the cat's ear hole had filled up the dirt that had fallen or blown up.

When I climbed out, the scenery outside had changed, and the weeds that had been around the high ground had disappeared as if they had been plowed over, replaced by craters, and several nearby pine trees had been blown to the stump of the trees...... But this is also a good thing, originally the devil was worried that those trees would be used by the Japanese army as a cover for the attack, but they didn't have time to cut them down because the battle situation was too tense, and the devil's artillery fire helped them a little.

Without thinking much about it, Zhang Chi grabbed his gun and lay on the trench that had become a small ditch to prepare for battle.

Looking down, the devils were divided into three directions and launched an attack on Tangji, 159 Heights and 311 Heights at the same time, among which the 159 Heights devils were the most, and they were only afraid of one squadron.

However, this is not surprising, the reason is that the 159 Heights are located at the forefront of the highway, whether the devils want to attack Tangji or 311 Heights, they have to pass through the 159 Heights and show their backs or flanks in front of the 159 Heights, so this 159 Heights is naturally a thorn in the side of the Japanese army, and it must be pulled out.

However, it was unexpectedly for a devil to attack on the high ground and attack in three directions at the same time.

The Japanese army is not a fool, they were ambushed by our army just now, they should know that the firepower of the Chinese army stationed in Tangji is not weak, and even they should see that Tangji and the 159 and 311 heights can support each other, so why are they still rushing up like this?

Then Zhang Chi quickly understood: the Japanese army was a light enemy, and they thought that the bombardment of planes and artillery just now had almost beaten the Chinese soldiers, or they wanted to take advantage of the fact that the Chinese had not yet reacted from the fierce artillery fire just now, and rushed into a distance of 159 meters and took the 159 heights with lightning speed.

In fact, Zhang Chi only guessed half right.

Commanding the battle was the commander of the 56th Wing of the 133rd Division, Kiyosuke Matsui.

Speaking of this, Matsui Kiyosuke and the Engineer Regiment really have a fate, and it was Matsui Kiyosuke's troops who fought in the first battle of the Wajie Iron Bridge and the breakthrough of the Engineer Regiment after that...... The 1st Brigade under Matsui Kiyoshi's assistant also suffered heavy casualties in the breakthrough battle of the Engineer Regiment, and even the captain Yuta Harada committed suicide and martyrdom.

For that battle, Matsui Kiyosuke was ashamed, because Harada Yuta reminded him several times that the Chinese had tanks, and they were advanced American tanks, but Matsui Kiyosuke didn't take it seriously. Matsui Kiyosuke was later proven wrong, and Matsui Kiyosuke paid a heavy price for it...... His first brigade was almost incapacitated.

Of course, Kiyosuke Matsui will not admit that he made this mistake, which has become a thing of the past with the suicide of Yuta Harada.

But what Matsui Kiyosuke didn't expect was that he would encounter a similar team again on his way to Lashio...... The other side has dozens of advanced American tanks, and the rifles are British Enfield, but they are Chinese soldiers.

"Is it the Chinese army again?" Matsui Kiyosuke couldn't help but be a little annoyed, and the Chinese troops had once again caused heavy casualties to his troops in a single face.

At this time, Matsui Kiyosuke received a call from the division commander: "Is there an enemy ahead?" ”

"Your Excellency, Lieutenant General!" Matsui replied: "The enemy has dozens of American tanks, the fire is very fierce, and our troops have suffered heavy casualties!" ”

"Matsui-kun!" Masao Watanabe said impatiently on the phone: "I don't want to hear about the enemy's situation, we are running out of time, I just want to know when you will be able to destroy this army and move on!" ”

"Yes!" Matsui Kiyosuke gritted his teeth and said, "Your Excellency, Lieutenant General, I need the assistance of artillery and the air force, and I will take Tangji before dark!" ”

"Good!" Masao Watanabe hung up the phone without saying anything.

So there was this Japanese attack, not only because the Japanese army underestimated the enemy, but also because of Matsui's anger and the Japanese army's desire to end the battle quickly.
