The heavy artillery equipped by the 10th Artillery Regiment is a special version built by Germany for the National Army, with a diameter of 32 times the caliber, which is heavier and more powerful than the German original, of course, the firing range is also longer, and the safety of the artillery is also better (the original German goods are prone to exploding after firing 1,000 rounds, and the 32 times caliber artillery chamber equipped by the 10th Artillery Regiment is safer), this battalion fired a salvo, and six heavy artillery shells flew straight along the predetermined trajectory towards the deep position of the Japanese army.

Let's say that at the moment before the heavy artillery battalion opened fire, Zhang Wei's preparatory battalion and the attacking troops of the other two battalions were still digging trenches, and the Japanese positions in front were subjected to shelling from the mountain artillery battalion of the 46th Division, while the main force of the 59th Wing was still not moving, and the infantry artillery squadron and the artillery squadron of the wing were preparing for the shelling.

Since the infantry artillery and mountain artillery were mainly flat fire (the 41-type mountain gun of the Wing Artillery Squadron of the Japanese Wing was an infantry type, and more emphasis was placed on direct fire), in order to shoot accurately, the artillery all advanced a certain distance, and the artillery who had just loaded the shells and completed the preparations immediately notified the commander of the 59th Wing, Ryoichi Itanishi.

Ryoichi Itanishi listened to the sound of artillery in the front-line position in the command post and watched the smoke and dust rising from the front line.

"Your Excellency, Wing Commander, the artillery is ready."

Ban Xiliang's face changed, the troops in the forward position have been hit by the artillery fire of the Chinese army, the Chinese army is still digging fortifications under their noses, and their own troops are equivalent to being pressed and beaten, and now the artillery is ready, just enough to attack the Chinese army in the trench.

"Okay, the artillery is attacking!" As soon as Ibansai Ryoshi gave the order to open fire, the liaison soldiers sent by the two artillery squadrons immediately ran out of the wing command post, and as soon as they walked out of the command post, a whistling sound was heard in the sky from the artillery position.

Some of the Japanese soldiers also looked up curiously, and it didn't take a few seconds for the experienced artillerymen to react to the source of the whistling sound.

"Shelling!"

Almost at the same moment when someone came back to their senses, twelve heavy artillery shells fell to the ground one after another, and the landing points were scattered in the middle and rear of the 59th Wing, and the shells exploded violently after they landed, and the soldiers on the Japanese artillery position only felt that it was dark in front of them, and the whole world became extremely chaotic, and the shells of the two heavy guns just smashed on the artillery position, and the other scattered ones smashed in various places in the rear of the 59th Wing.

The result of the explosion of two heavy artillery shells on the artillery position was quite tragic, one shell directly smashed on a 41-type mountain gun, directly tore the artillery from the gun carriage, the gun bolt to the gun body, and all turned into scrap metal, and the other shell detonated the shell box of the 92 infantry gun when it exploded, and the chain reaction produced by the shell explosion blew up an infantry artillery squad, plus the shell shrapnel and various fragments scattered everywhere, the Japanese artillery position was already miserable, and the human body and the cannon body damaged by the artillery were twisted and crooked.

The explosion of the two shells caused heavy casualties to the Japanese gunners, and a Japanese officer who had not yet been killed got up from the ground, looked at the tragic scene around him, but was not intimidated: "Get up all, transfer the artillery and equipment, and push to the hidden position!" ”

After the first round of shelling, there were still three infantry guns left in the Japanese army, and two of the 41 mountain guns were damaged.

Compared with the artillery, there were more casualties, an infantry artillery squadron, a mountain artillery squadron, almost half of the casualties, after the Japanese officers shouted a loud reprimand, the Japanese soldiers who fell to the ground and did not die also knew the truth that it was not appropriate to stay here for a long time, endured the pain and physical discomfort, one by one disgraced, covered in blood to get up, and quickly pushed the intact artillery to retreat.

"Retreat!"

"Keep the artillery hidden."

In the chaotic noise, the Japanese gunners who had been bombed desperately pushed the artillery back to the hidden artillery position, and the mission of harassing the Chinese army with artillery was of course temporarily suspended, and there were still some wailing wounded soldiers, stumps, and corpses on the ground, and at this time, it was too late to care about them.

The round of artillery bombardment just now directly destroyed nearly half of the support artillery of a Japanese wing, and the other shells fell on various places in the defense of the 89th Wing, and one shell fell at the door of the command post of Ryoichi Itanishi, killing several signal soldiers of the wing headquarters, and the other shells also caused more or less casualties to the Japanese troops everywhere.

"Order all units to strengthen their fortifications, not to act rashly, and to cancel the shelling and harassment." Banxi Liangyi said in shock, the power of this artillery bombardment is obviously a large-caliber heavy artillery, at this time Banxi Liangyi still has the intention of attacking, first ask the troops to protect themselves, so the Japanese position that was shelled began to repair the fortifications.

On the position of the heavy artillery battalion, after the first round of shelling, the Chinese artillerymen on the position looked into the distance, and the smoke and dust produced by the death of the Japanese artillery position were clearly visible. The shelling caused a chain of shells that could be seen clearly even from such a distance.

After the artillery completed the work of cleaning the chamber and reloading the shells, the second round of shells was fired, and the grenades were still using charge No. 8, after the first round of firing, the officers of the heavy artillery battalion judged that the first round of shelling was basically successful through the smoke produced by the Japanese martyrdom, and only slightly adjusted the second round of shelling, and the speed of the shelling gradually increased, and then the third and fourth rounds of shelling were fired.

Several successive rounds of shelling tilted dozens of heavy artillery shells towards the Japanese positions, and the Japanese troops in the depths suffered considerable losses under the heavy artillery shelling, and the most important thing was that their front-line troops were suppressed by mountain artillery, and the depth was suppressed by heavy artillery, making it difficult to take action against the attacking troops exposed to them.

In the continuous artillery bombardment, Zhang Wei and his attacking troops gradually dug fortifications.

"The little devil was blown up!"

"Fight for a little bit of air, and the work in your hands is sharper."

With the sound of artillery, with the efforts of the three battalions, a trench gradually took shape, and the soldiers connected the dots to form a line of improvised trenches, and the excavated soil was piled up outside the trench, compacted and compacted, and used as a defense against shrapnel.

Zhang Wei's preparatory battalion was in the center, and the other two battalions of friendly forces were on the flanks.

In order to prevent accidents, under the coordination of Zhang Wei, this row of tanks retreated to the front of the first trench of the Japanese army, away from the eyes of the Japanese army, and at the same time took this opportunity to contact the rear to supplement the tank machine gun ammunition that consumed a lot in the offensive operation.

The construction of the temporary fortifications of the attacking troops was basically completed, and the men of each battalion entered the fortifications to avoid the dilemma of being directly exposed to the low noses of the Japanese army, and the Japanese fortifications in front of Zhang Wei were next to the shelling of the mountain artillery battalion of the 46th Division, and then the 82 mortars of the 276th Regiment of the 46th Division advanced a certain distance overnight and joined the artillery bombardment of the Japanese positions, and the tactical goal of the Chinese army to cover the attacking troops with artillery bombardment was also achieved.
