In the position of the preparatory battalion, the officers and men were waiting for each other, and as the minutes and seconds passed, when the hands on Zhang Wei's watch pointed to 5:38 a.m., smoke screens burst out from the mountain artillery positions in the rear, and six Bofors 75-caliber mountain guns bombarded the Japanese positions.

According to the instructions received by Zhang Wei in the 276th Regiment, the mountain artillery battalion of the 46th Division will carry out a one-and-a-half-base suppressive shooting on the Japanese positions before 54 o'clock in the evening.

According to the regulations of the national army, when the ammunition reserve is insufficient, the ammunition storage of the troops is one and a half bases, and the troops enter the theater to participate in the war, and after the ammunition is replenished, they will carry two bases of ammunition, and the logistics departments and military stations in the rear will store one base for the forward troops.

That is to say, when the national army troops were fighting, the ammunition reserves on paper were three bases, and the 46th Division ordered the mountain artillery battalion to shoot one and a half bases, which was indeed a bloody investment, which can be called an act of emptying its own artillery shells.

The Bofors 75-mm mountain guns equipped by the national army, the 75-mm mountain guns of the six-year Taisho style of the Japanese Taisho and the 76-mm mountain guns aided by the Soviet Union, the equipment of these artillery pieces is relatively large, the caliber is relatively similar, and the artillery performance is relatively advanced, the ammunition of a base is 150 rounds, which is converted into a half-base number is 225 rounds, and a single cannon fires 225 rounds, which can be said to be a lot.

Therefore, during the firing of this attack, the mountain artillery would definitely not have knocked out the terrifying number of 225 rounds with a single artillery, and it could only reach one-third, due to the insufficient ammunition replenishment before the war and the consumption of the previous shelling of the Japanese army.

Six guns shelled the Japanese positions in a rapid-fire manner, and one after another the shells fell on the Japanese positions, and there were explosions one after another, and there were a small number of shotguns in the first round of shells, and the steel balls produced after the explosion flew everywhere and scurried around the Japanese positions.

"Good fight!"

"Let these little devils taste the bombardment!"

After the artillery bombardment began, the soldiers of the national army in the position applauded one after another, and it was indeed very pleasant to see the Japanese being bombarded by their own mountain artillery at close range, Zhang Wei did not give the order to attack, and there may be a certain deviation in the initial bombardment, and the artillery will have shells exploding outside the Japanese position, and the charge will cause accidental injury, and it is necessary to wait until the artillery observer will run to shoot Zhu Yuan corrected, and the infantry charge will not begin.

In the position of the Japanese army, the shells that continue to fall make the surface of the position more craters, the steel balls after the explosion of the shotgun make the Japanese army hiding in the anti-artillery hole no longer sit back and relax, ordinary shells only rely on shrapnel to kill after the explosion, a large number of steel balls after the explosion of the shotgun are really flying around, and some shells are just not far from the anti-artillery hole.

The steel ball by the power of the explosion, directly into the anti-artillery hole, in the outermost side of the anti-artillery hole Japanese troops suffered one after another, left in the foxhole in the foxhole several Japanese observation posts in the first round of artillery almost all killed, the corpse died extremely miserable, at the same time by several steel ball piercing the body, the head was hit by the steel ball, half of the skull was lifted off, only the chin remained, the gun in the hand happened to also hit the steel ball, was stopped and cut off.

Zhang Wei raised the binoculars, as he expected, at the beginning of the shelling, a lot of shells were crooked, smashed to the outside of the position, the corpses of the brothers killed during the feint were still lying in front of the Japanese position, the crooked shells exploded in front of the Japanese formation, covering the bodies of the dead brothers, the shells do not distinguish between the dead and the living, let alone the enemy and me, after the adjustment of the artillery observers, the landing point of the shells gradually and accurately concentrated on the Japanese positions, according to the speed of rapid fire, the duration of the shelling will reach 15 minutes, and the shelling began at 5:38, Theoretically, the shelling would have ended at 5:53 a.m.

Zhang Wei considered that the infantry of his reserve battalion needed to advance under the cover of artillery fire, and they had to launch an attack before the artillery fire stopped, and the troops had not undergone systematic infantry and artillery coordinated training, so in order to prevent accidental injury, he set the time of the attack at 5:45 a.m., and there was artillery fire cover at this moment, which could also minimize the possibility of accidental injury.

The sound of shells whistling over the sky was intertwined with the sound of shells exploding violently, and in two minutes, their troops were about to start storming.

"Pass the word, all ready to fight, listen to my orders!" Zhang Wei shouted to the soldiers around him at the top of his voice, and the soldiers passed the news to the ears of their comrades, and then the 37th Battle Anti-Artillery Company at the back of the position.

The first attack echelon was the first company and the second company, and the two companies with strong combat effectiveness under Zhang Wei were responsible for directly attacking the Japanese position, and they were also the first troops to break out of the trenches.

At the beginning of the Japanese artillery bombardment, the observation posts arranged on the position were all killed, or died from shotguns, or died from grenade shrapnel, and the observation of the movement of the Chinese army could only rely on a small number of people left behind in the pillbox, and observed the situation of the national army through the observation port, although the Japanese fortress was relatively strong, the bombardment of the 75 mountain artillery would not cause fatal damage to it, but in the shelling to put the head close to the pillbox firing port is also an extremely courageous job, after all, such a large blank, who can guarantee that the shrapnel of the shell will not come in.

The Japanese soldiers who were wounded and not dead due to the shelling in the anti-artillery hole let out a terrible howl, extremely painful, and could not be relieved, two wounded Japanese soldiers who really couldn't stand it rushed out of the anti-artillery hole, let the shells give themselves a good time, but the other Japanese troops did not have such great courage, most of the time, it is always more difficult to die than to live in pain, the heart-rending shouts and the explosion of the shells intersected with each other, casting a shadow on the psychology of the uninjured Japanese soldiers, and gradually some people felt that this shelling, It was not simple to foreshadow the offensive of the Chinese army.

The rapid fire of the mountain artillery will start quickly, after firing for a while, the speed of the shelling will slow down, even if the shells are enough, the breech of the artillery will not be able to stand it, the dense falling shells will turn into regular and sparse shelling, the gunners in the mountain artillery positions will shoot shirtless, the Bofors mountain artillery will be surrounded by a pile of knocked cartridge shells, the barrels will begin to smoke, the physical strength of the shooters will also drop a lot, the speed of shooting will begin to slow down, and the six guns will begin to fire regularly.

The reduced density of the firing facilitated the charge of the gunners and the preparatory battalions, and likewise, the Japanese troops in the positions were also given the advantage of observation, and the observation posts in the forts could observe the movements of the Nationalist troops in a relatively safe situation.

"Pass my orders, everyone has them, start attacking!" Zhang Wei shouted, the sound spread throughout the position, the density of the shelling decreased, he shouted as hard as he could, and the soldiers of the preparatory battalion could basically hear it.

"Kill!" Qiu Wei stood up from the crowd of the first company, held high the Zhongzheng rifle, and led his men to rush out of the trench first, and the second company led by Mu Chao, followed by the first company, launched a charge, and the shouts of killing resounded through the position of the preparation battalion.
