The reason why Zhao Ergou did not shell the Japanese artillery positions calculated by the forward artillery observers through ballistics and direction and time analysis is very simple.

Time difference.

According to the calculations of the artillery observers, the mountain artillery here is about to land and prepare again, and the time difference of one and a half minutes is enough for the Japanese mountain artillery to slip away again.

Although the 20th Division is not a mechanized corps, its degree of mechanization far exceeds that of the Chinese army. The special forces at the front had already informed the rear long before the battle, and the Japanese artillery wing, transporting ammunition and 105 howitzers, were all carried by trucks, mountain guns and field guns, mostly dragged by horses.

And this mountain artillery position, which was quickly transferred, Zhao Ergou had reason to believe that they used trucks. Thousands of meters in front of the old pass, there is a flat valley, and the truck dragged more than 500 kilograms of 41-type mountain guns to run, and 2 minutes is enough to run out hundreds of meters.

Therefore, Zhao Ergou let the two guns report to the artillery observer respectively, and the left and right sides of the position were extended by nearly 500 meters for 10 rapid fires.

As for why only 10 rapid fire shots, because, Zhao Ergou also has to run away! He was sure that the reason why the little devil knew that there was a mountain artillery on the side of the independent regiment and dared to cover it for so long was also to use it as a bait to lure the prey out of the hole.

Twelve 105 howitzers were waiting for his mountain artillery battery to retaliate for the shelling, and then wipe out the artillery of the independent regiment in one fell swoop with fire coverage.

From the time the Japanese artillery observers reported to the start of the firing of the Japanese howitzer group, he was left with a maximum of five minutes.

The reason why the Japanese army reacted faster was because their 105 howitzers had a large killing area, an 18-kilogram projectile killing radius of 22 meters, and a salvo of 12 guns could cover an area of nearly 15,000 square meters.

Sure enough, after firing ten shells, two three-jumpers pulled two guns, and the other three three-jumpers pulled an artillery platoon along the valley wildly, running out of the valley in five minutes. Japanese howitzer shells smashed over.

After five or six minutes of indiscriminate bombardment, at least 100 high-explosive shells turned the 600-meter-wide and 800-meter-long hillsides and valleys into a sea of fire.

The Japanese artillery, which had always been extremely economical, even counted the number of artillery shots, fired hundreds of grenades in one go, which shows their fear of the independent regiment, which was a few mountain guns that were well hidden.

The 105 howitzer group was originally the most powerful weapon of the Chinese and Japanese armies on the entire Niangziguan front, and originally with the idea of the Japanese 39th Brigade Takagi Yoshito, this battle was undoubtedly won, but it just depends on how he wants to fight and what price he is willing to accept to take Niangziguan.

These 12 105 howitzers are his greatest confidence, no matter how hard and dangerous the fortifications are, they are all powdered in the bombardment of the 105 howitzer 18 kg projectiles.

But he didn't expect that as soon as the 105 howitzer showed its muscles to the independent regiment stationed at Jiuguan, the mountain artillery shells of the independent regiment flew over. The firing range of the 105 howitzer is as high as 10,000 meters, and the distance from the Jiuguan position is also as high as 6,500 meters, which is almost the limit of the mountain artillery.

However, it was the Japanese army's 41-type mountain artillery, and the Bofors mountain gun equipped by the independent regiment could also have a firing range of up to 9,000 meters.

This frightened the commander of the 26th Wing of the Japanese Artillery, Hosokawa Nakayasu, and hurriedly gave up the artillery position that had been selected and retreated back more than 1,000 meters, which was a peace of mind. Although the 105 howitzer is very powerful, if it is shelled by a mountain artillery, the consequences are actually the same as being attacked by a howitzer of the same power. As long as one howitzer shell explodes on the position, the entire artillery squad can be sent to the sky. Even if the distance between each of their guns has been reduced by 10 meters from the textbook safe distance of 40 meters.

The independent regiment still has artillery with such a range, and the two of them, Takagi Yoshiren and Hosokawa Nakayasu, still don't regard the artillery battalion of Zhao Ergou, who is clearly written in the intelligence, as a henchman?

This time, Hatori Nakasa used the mountain artillery of the artillery squadron directly under the wing to cover the infantry charge from an extremely dangerous distance, not so much because he was in danger, but because it was also at the behest of Yoshito Takagi. When necessary, use infantry and these mountain guns as bait to lure out the artillery of the independent regiment and annihilate it in one fell swoop.

They had even calculated that if the mountain artillery continued to cover the infantry attack position, the mountain artillery of the independent regiment would definitely not be able to bear the artillery retaliation. Because their mountain artillery has a longer firing range than the 41 mountain artillery, it definitely has the ability to retaliate against artillery fire.

I have to say that the commanders of the Japanese army at these two levels are all old and calculating, from the infantry attack to the artillery battle on both sides, they are all counted one ring after another.

As for the infantry on the position and those mountain artillery, they are naturally just pawns of small soldiers on the chessboard, even if they are eaten, but as long as the artillery of the independent regiment is eaten, the 105 howitzer can no longer have any scruples, in the opinion of Yoshito Takagi, it is worth it.

Words such as "mercy does not command the army" and "one general will achieve ten thousand bones wither" are not only applicable in China, but also in Japan.

The little people are just numbers in the eyes of the big people after all.

It can be said that in this not particularly large-scale offensive and defensive battle, both sides of the enemy and us are playing their own cards, trying to see each other's hole cards, and then eliminate.

The hole cards of the Japanese army have been played, and their goal has been achieved. They waited for the artillery of the Separate Regiment to open fire, and at the same time found the artillery position.

They just didn't expect that the artillery of the Separate Regiment was semi-mechanized, and although there were no trucks, there were Rolls-Royce brand three-jumpers, towing 680 kg of Bofors mountain guns with two wheels, which could maneuver over the mountains at a speed of almost 15 yards per hour.

Looking at the artillery fire less than 300 meters away, even Zhao Ergou couldn't help wiping a cold sweat, fortunately he only ordered 10 rapid fires, if he was a little greedy and ordered 20 rounds per cannon, then this time, he and the No. 30 brothers in the third platoon of the artillery company, together with two Bofors mountain guns worth tens of thousands of oceans, would be blown up into the sky by the howitzers of the little devils.

Don't look at 300 meters, it looks very far, but for the 105 howitzer, which is a sea of fire within a radius of thousands of meters with one shot, it is just a matter of firing a few more shells.

There was no time to celebrate his wisdom, Zhao Ergou continued to run away with the artillery platoon, what if the muzzle of the Japanese artillery was crooked?

The Japanese artillery wing was actually trying their luck, and they were waiting for the report from the front with their eyes after firing hundreds of shells in one breath, and they couldn't see if the Chinese mountain artillery was still shelling. As long as there is no shelling, I am not sure that I killed them, but at least I said that I drove them away.

The artillery of the Separate Regiment was running away, there was no shelling. However, the intensity of the Japanese shelling was also much reduced.

Zhao Ergou's two cannons just now fired ten rounds of rapid fire were not useless. Or rather, shit luck.

He imagined that the Japanese mountain artillery was likely to be towed by trucks, so it was so maneuverable, but in fact, he really thought too much.

The artillery wing and the infantry wing are under the command of the 20th Division, but in fact, they are two arms, not to mention that the feather bird Nakasa has to be respectful on the side of the commander of the artillery wing, even if it is a big saku, he must also be polite to others. There is no artillery wing, your infantry wing wants to attack the city, so let's go with more dead!

The trucks that were only rationed to the artillery wing, Nakasa Hatori didn't even think about it. The mountain artillery he commanded was still transported by pack horses and camels or haulers. It's just that the weight of the Japanese-style 41 mountain cannon is lighter, and the terrain is relatively flat, so it slips a little faster.

But Zhao Ergou was not mistaken, the Japanese artillery did move to the left wing of the two wings. It's just that their speed is not so fast, when Zhao Ergou covered the shelling of 10 rapid-fire shells at that position, the Japanese artillery squad drove the horse and pushed the artillery, in fact, it only walked more than 300 meters, and it was still 200 meters away from the location where the nearest shell exploded.

The artillery battalion is full of veterans, and every year there are dozens of rounds of live-fire experience, and the guns are all fired extremely accurately. All 10 shells landed accurately in the target area.

At this time, it is a mistake to hit accurately, and if there is a crooked hit, perhaps, it is more threatening.

Anyway, looking at the explosions that kept banging 200 meters away, there was no threat to the Japanese artillery.

If it weren't for the fact that a pebble had galloped 200 meters in the air and struck the balls of a strong pack horse that was dragging a cannon.

The vast majority of people who play football have the experience of being kicked by a football. Think about it, if such a big ball hits that critical position, you can turn pale in pain, what if you replace it with a small stone? Even if the small rock has been running wildly in the air for 200 meters, the kinetic energy has been decayed.

So, suddenly, the strong stallion with a sense of being castrated went crazy, and with a long roar, he drove another horse to gallop wildly, dragging the 500-kilogram mountain cannon behind him, and knocked several Japanese artillerymen who were caught off guard.

When the Japanese artillery who reacted wanted to stop it, the hundreds of kilograms of brute force of the horses that had gone crazy could be pulled by their little arms and legs? The helpless artillery squad leader had to order to kill the pack horse that was attacked but the adrenal glands were soaring, and the small pistol he wore in the south was naturally the best choice, and the southern fourteenth pistol that was easy to get stuck was not stuck at this time, but the power was too small, and the two shots did not kill the startled horse, but it made the frightened horse in severe pain even more panicked, and after running 150 meters, in the desperate eyes of the Japanese artillery, he plunged into the ravine, along with the mountain artillery.

Looking at the mountain artillery lying in the ravine more than ten meters deep, except for the barrel that had not been deflated, and the rest were almost shattered, the Japanese artillery squad leader was in tears.

Baga, this is also unlucky。。。。。。

The mountain artillery was killed by Zhao Ergou in this way, and he also killed two pack horses and injured three Japanese soldiers.

It can only be said that war, in addition to strength, also depends on a part of luck.

At least at this moment, luck is on the side of the independent group and the wave group.
