There was nothing to do all night, the Japanese army did not act, and Wang Lung did not let the soldiers go down the mountain to tell the devils to get up and pee, but let them sleep well and wait for the big battle at dawn (the devils are generally called soldiers, and the Eighth Route Army is generally called soldiers).

At five o'clock in the morning of the next day, Bao Keshou ordered all the troops to immediately boil the pot and cook.

After eating, Bao Katsusu had the artillery as the main attacking force and the infantry brigade as the reserve.

Outside the pass, all the troops formed a formation, first opened the way with artillery, and blew up the land near the pass, with the intention of using artillery shells to clear mines.

This was followed by 20 artillery guns of 90 wild mountain guns firing at the same time, and huge shells flew towards the pillbox of the Eighth Route Army in the mountain pass with a long tail in tow.

At the same time, Bao Katsushou ordered a squadron to immediately launch a tentative attack on the Eighth Route Army fortifications entering the mountain pass, hoping to see if it could capture the entrance to Montenegro in one fell swoop.

Violent explosions continued to sound overhead, but the soldiers in the bunker were not afraid at all, they knew the fortification of the bunker.

In the words of the detachment commander, unless the Japanese army brought in heavy artillery (more than 105 mm is considered heavy artillery), at most blow up the dirt and sleepers on it, and don't think about hurting the pillbox.

After the shelling, the fighters saw more than 500 little devils rushing towards the forward positions.

After the imp is in effective range, after the starting gun is fired, all the bright and dark bunkers fire at the same time.

More than a dozen heavy machine guns opened fire at the same time, blocking the road into the mountain, and the attacking devils were immediately knocked down in a large area, with heavy casualties.

The purpose of the test had been achieved, and the fire of the Shina people was really fierce, and Horibe Ryuichi, who was in charge of the front line, immediately ordered the attacking infantry to withdraw immediately.

At the same time, Bao Keshou and the others, who were watching the battle not far away, were secretly afraid, and they all saw it when the Eighth Route Army opened fire just now.

The fire points composed of so many light and heavy machine guns almost blocked the road into the mountain, and even if everyone was thrown into battle, the result would not change anything, and it would only increase the casualties of the imperial army.

And the effect of the shelling is also very unsatisfactory, the caliber of the Type 90 field gun is only 75mm, and the lethality of the bunkers hidden in the semi-underground (pillbox, which is half underground, and the ground is squad) is very small.

Since the shelling failed to destroy any of them for more than ten minutes, this made Bao Katsushi even more dissatisfied with the Type 90 artillery.

The suppressive artillery used by the Japanese Army in the past was the Type 38 field gun, but this kind of artillery produced in Germany was designed in 1888, and the Japanese Army spent 4 million yen in 1905 to buy it from the German Krupp company, and because that year was exactly Meiji 38, it was named the Type 38 field gun.

Although the performance of the Type 38 field gun is good, after all, it is a product of half a century ago, so as early as 1920, the Japanese Army began to plan a new type of field artillery.

However, at that time, because of the naval fleet, the Japanese Army was very poorly paid, and later the Kanto earthquake and economic depression, for the development of new artillery technology, the Japanese army still considered relying on foreign technology, and sent a foreign inspection mission, and finally focused on Schneider Company.

In 1928, Schneider began to design a new gun, and in 1930, after several rounds of revision, the prototype gun was completed, and in 31 the design was finalized, and in 32 it began to be produced at the Osaka Arsenal and named the Type 90 field gun.

However, the Type 90 field gun was 300 kilograms heavier than the Type 38 field gun, and the department in charge of operations at the General Staff Headquarters was very dissatisfied with the excessive weight of the new artillery.

However, the new artillery was carried by the 2nd Division to participate in the actual combat after 918, and the feedback was that the extra range was more cost-effective than the extra weight.

This allowed the Type 90 artillery to officially enter production, but the output was not high, only a few hundred, and the mixed division of Bao Kashou had such a batch of equipment Type 90 field artillery.

In fact, what Bao Katsushi didn't know was that it was not the bad effect of the shelling, nor the reason for the artillery.

But when it was built, Xuanyi had a lot of steel bars and iron plates added to it, and also thickened the concrete of the bunker (the bunker is divided into a bright fort and a dark fort), even if the heavy artillery came and hit it, it could not be destroyed in a few strokes.

The artillery bombardment was ineffective, the infantry's tentative attack was blocked, and the requested aviation was delayed, and Katsutoshi could only hope for Horibe Ryuichi's earthwork.
