Speaking of the temporary fortifications built at each machine gun point, in fact, it was also discussed after some discussion.

The point is, a matter of time and materials.

Although there is enough material, there is not enough time.

After everyone's consultation, there is this seemingly weird, but actually very practical fortification.

A fortification two meters long and one meter wide was built with bricks, and half of it was covered with a stone slab up to fifteen centimeters thick.

In this way, the three machine gunners can hide inside at the same time, and when the little devil's fighter swoops down to strafe, everyone can hide to avoid being directly strafed, and when the fighter strafes past, everyone can stand up and rush back to them...... To put it bluntly, it is actually to take advantage of the weakness of the fighter that cannot shoot vertically at 90 degrees to dodge and shoot back.

Of course, if you are hit by the * of the bomber, it can only be said that you are too lucky. After all, this is war, and unless you hide in a bomb shelter and maybe avoid death, there is no 100% safe place, let alone fight back while avoiding death.

Although the five fighters flew away, the little devil's bomber turned a corner and came back, and this time, everyone could concentrate their firepower more boldly to strafe the little devil bomber.

In the past, because the Eighth Route Army did not have an air force, the little devil fighters and bombers generally flew relatively low in order to achieve better results and carry out more accurate bomb dropping or strafing.

This time, the same goes for the bombers of the little devils.

However, when dozens of light machine guns concentrated their fire on the bombers, the hit rate against the imp bombers was greatly improved.

The pilot on the little devil bomber immediately felt the pressure...... Didn't you hear the sound of bullets hitting the fuselage of the plane from time to time on your plane?

If this continues, if a bullet really hits the key part of the bomber, it is really possible to shoot down a little devil bomber.

So, the pilot of the little devil bomber quit and immediately called the fighter pilot not far away, asking them to hurry over and escort the bomber...... At this time, your fighters have lost their strafing targets and can rest on the side, but the mission of our bombers is far from over, you must ensure that we can successfully complete the bombing mission, otherwise, if the bomber's mission cannot be completed because a bomber is shot down, can you still drive the fighter to carry out a suicide attack to help us complete the mission?

Whether the fighter pilot likes it or not, but an order is an order, and if he doesn't want to go to court-martial, he can only come over to help escort him.

As a result, the next battle was a bit similar to the way Li Jing and their commanding heights dealt with the little devil air force.

If you are bombed by a bomber, you are considered unlucky...... But the crux of the matter is that the bomber will never bomb a certain machine gun point regardless of its previous mission, that is to say, the bomber commands to bomb the intended target, and this leads to the fact that most of the machine gun points are safe, and only a few machine gun points in the bomber target are bombed.

As for dealing with the little devil fighter, it really depends on eyesight and speed, but as long as you dodge in time, it is generally very safe.

As for the little devil bombers, first, they fly at a high altitude, and it is difficult for the machine guns to hit; second, with the addition of fighters, most of the machine gun fire is dispersed, so that the machine gun point cannot concentrate fire against the bombers, so that the safety of the bombers has been greatly improved.

For the little devil fighter, the speed of the fighter and its own hardness greatly reduce the probability of being shot down, of course, the premise is that the fighter cannot fly too low, let alone send himself to a place with a high density of machine gun points.

In this way, the two sides went back and forth for more than half an hour.

As a result, three machine-gun points, nine machine guns and their machine gunners died. None of the other machine gun points were injured.

And the little devils, whether they are fighters or bombers, although they were not shot down, they more or less left some bullet holes in their bodies.

Zhang Qingshan was not satisfied with such a result, but he was helpless, who called the Eighth Route Army poor, and the background of the assault regiment could only be said to be relatively better, not to mention compared with the little devils, even compared with the national army. Not to mention fighters, there are not even anti-aircraft guns, and it is already good to be able to disrupt the bombing of the little devils.

And the little devil was not satisfied with such a bombing result, because, under the disturbance of the machine gun point, the bombing of at least three targets by the little devil bomber did not achieve any effect, which was already a failure for the little devil bomber...... There were only 11 bombing targets in total, and as a result, under the cover of fighter planes, on the premise that there were no anti-aircraft guns in the locality, and the county town was so large, the targets were relatively concentrated, and only eight of them were blown up, and no one would be satisfied with this result.

In fact, the crew of the little devil bomber and the pilot of the fighter, after returning to accuse each other of not doing their best...... This kind of ruffle is the norm among the three branches of the little devil's armed forces, but it is relatively rare within the Air Force. It can be seen that both sides are holding back their anger in their hearts.

And it didn't end there.

Just when the bombing was about to come to an end, the little devil army also took action, and it suddenly changed the pattern of the entire battlefield, or the tactical deployment of the assault regiment.

Judging from the fact that the little devil seized the time to start the move very accurately, the little devil's tactics were obviously carefully deployed and prepared in advance...... When the bombing began, the little devils were eating, and in the middle of the bombing, the little devils began to assemble, and at the end of the bombing, the little devil army began to attack.

The little devils still use the old tactics of the past: first shelling, then attacking.

"Boom, boom, boom......"

The little devil who got the ammunition replenishment is now alive again.

No, I didn't do it for a few days, but as soon as I started today, I first used mountain artillery to slam the city wall, and the target of the shelling was very accurate: it was the section of the city wall that exploded a few days ago and was hastily repaired in the past few days.

In fact, this section of the city wall is really unlucky: first it was exploded by Liu Bing, and the entire city wall was gone. Then it was finally repaired for a few days, and as a result, he was taken care of by the little devil bomber. It was not easy to get past it, but it did not collapse immediately, and as a result, it was bombarded by the mountain artillery of the little devils in turn, and now, it has finally completed its historical mission.

Under the bombardment of the Little Devil Mountain Cannon for five minutes, the upper end of this section of the city wall was finally blown out of a large hole about three meters deep and six meters wide.

However, this is still about three meters away from the ground, which is also not conducive to direct climbing.

Don't be afraid, the little devil now has cannonballs, and the city wall will not run away with long legs on its own, so when the little devil saw this effect, his morale was greatly encouraged, and he immediately stepped up the shelling of this section of the city wall, and it was to use the left side of this opening as the precise running pole, and constantly shelled.

The artillery skills of the little devil artillery are good, and the distance is close, at least nine out of ten shells hit the precise target within three meters.

The explosion of each cannonball makes this section of the wall tremble and drop a lot of gravel and dust. Not to mention the ground, which has long been trembling at the sound of explosions, and has not stopped.

And so, for another three minutes.

Finally!

"Boom!"

With a dull loud bang, this section of the city wall finally collapsed into a hole seven or eight meters wide at the top and two or three meters wide at the bottom.

The little devils suddenly erupted in a burst of excited cheers as if they had already won.

The little devil artillery didn't seem to be satisfied, so he actually slammed it for another minute, widening the lower end of the opening to about five meters, and finally stopped the shelling with satisfaction.

At this time, the little devil infantry had already rushed to half the distance.

Regarding the bombardment of the city wall by the little devils, Zhang Qingshan and others had already judged it and made corresponding arrangements.

Speaking of this deployment, it is really enough to show that Zhang Qingshan and they racked their brains for this battle.

Zhang Qingshan had already learned from Tian Guozhong that the little devil plane could not only bomb and strafe, but also play a role in battlefield reconnaissance.

For some permanent and solid fortifications, there is no way to conceal them, but for some temporary fortifications that can be stacked at any time, but can play a huge role, Zhang Qingshan and others put the materials aside first, and then quickly put them in place according to the needs of the environment when needed.

This not only saves time and effort, but also avoids detection to the greatest extent, so it has been unanimously supported by everyone.

One of the most popular of these is the circular fortification made of sandbags: if the sandbags are prepared in advance and placed under the eaves, they can be avoided detection. When needed, twenty warriors, each carrying a bag of sandbags, piled up in a circle, can become an important part of street warfare - ring fortifications.

This is not only simple and convenient, but more importantly, it can also be placed anywhere according to the needs of the battlefield...... Twenty people carried sandbags under the eaves to a place about ten meters away and stacked them into a ring of fortifications, which only took a minute at most.

For this purpose, Zhang Qingshan and the others prepared 2,000 sandbags, half of which were piled up under the eaves of the street not far behind the wall facing the little devil.

And the little devil aircraft did shoulder the task of reconnaissance, but all they saw was that the farther they went to the center of the city, the more fortifications and other fortifications on the side of the street, but within a hundred meters of the city wall, except for one or two pillboxes at the crossroads, there was no fortification anywhere else.

However, the scouts on the little devil's plane absolutely did not know that just as their plane flew away, when the little devil launched an artillery bombardment on this section of the city wall, Liu Bing, the commander of the first battalion of the assault regiment, gave an order, and hundreds of people in the first battalion immediately took action, carrying the sandbags that were originally hidden under the eaves to the side of the street or to a designated place on the street in advance, and quickly superimposed them into a ring of fortifications.

The little devil really trusts the aircraft reconnaissance too much, and he really didn't notice this, plus the mountain cannon is not a small steel cannon, and it can't get into the small steel cannon like a small distance parabola-like hanging bomb, which also gives the soldiers of the first battalion plenty of time and maximum safety.

Therefore, it is normal for the little devil infantry to be dumbfounded next......
