In the beginning, only artillery and some of the shells accompanying the army came, and more shells, especially the large-caliber shells used in heavy artillery, were still on the way.

In the past few days, it has been in place one after another.

Now that he is well prepared, Lin Ziran will naturally not delay time, and this extra day of delay will give birth to one more variable, and the ghost knows whether Shao Bing and Du Zhikuan will directly send troops.

In order to avoid many nighttime dreams, Lin Ziran officially ordered the troops to attack on the first day of preparation.

It was still the artillery units that launched the attack first, and it was the artillery of the experimental artillery battalion!

At a distance of about 2,500 meters from the head of the Dingjiang fortress and about 1,500 meters from the Luo River to the east, six 75-millimeter guns and one 150-millimeter gun of the experimental artillery battalion were lined up.

In fact, the terrain of this place is not too good, there are no defensive measures such as anti-slopes, and it is basically empty, but this place can be located at the center point, and it can be used to bombard the Dingjiang fortress to the south, and to the east it can block the Luo River to support the Luo'an fleet in battle.

With the order of the artillery commander, these seven guns opened fire one after another at the target that had been aimed at a long time.

In the rumbling cannon, six small and one large cannonballs crossed the curve of the sky and fell into the head of the Dingjiang fortress with a whistling sound.

And the landing point is very concentrated, all of which fall on a high platform on the northwest city wall of Dingjiang Fortress.

There, it was the second largest large artillery battery in the Dingjiang Fortress, with at least 20 artillery pieces deployed, and all of them were heavy guns, which passed through a wide firing range and turned the muzzles to completely block the land range to the west and north of the Dingjiang Fortress.

However, at this time, this huge battery was kicked up with clouds of smoke and dust, shrapnel flew sideways, Rao is this battery is an open-air battery, but in fact, between the artillery and the artillery are sandbag fortifications, and the front of the battery is also a sandbag fortification.

However, if it is directly subjected to heavy shelling, it will still suffer great losses, after all, this is not a cement pillbox, the top is several meters thick.

In those days, the forts were mostly open-air!

After these seven shells fell into this heavy artillery position, they set off not only smoke and dust, but also not only rumbling loudly, but also countless casualties.

In particular, the 150-millimeter shell, which fell into the enemy's heavy artillery position and exploded, brought the advantage of the huge charge to the fullest.

Next door to the place where the shell landed, there was an artillery group, and this artillery group was actually protected by sandbag fortifications, so the shrapnel after the explosion of this 150 mm grenade was basically blocked, but the huge shock wave was alive and directly killed many members of this artillery group.

More than a dozen enemy gunners who were carrying the shells behind the shell landing point, even though they were actually more than ten meters away from the shell landing point, but they were still overturned by the shock wave in an unprotected state, and many of them were even more bloody and blurred, and at a glance they knew that they were killed by shrapnel or steel balls inside the shell.

The other six 75-millimeter shells also caused certain results, and these 75-millimeter cylindrical grenades, which seem to have a small caliber, have a slightly more actual charge than the 120-millimeter round grenade, which has a very good effect when it explodes.

For a while, this heavy artillery battery, which Li Dingjun regarded as the core of land defense, instantly fell into a panic, blood flowed everywhere, the wounded screamed, and the survivors either hid and shivered, or ran away.

The artillerymen of the experimental artillery battalion on the other side were already nervously resetting the artillery.

The artillery commanders and platoon commanders all shouted something like: "Hurry up, move faster!" words.

Later, the battalion commander of the experimental artillery battalion, Dr. Tian Yaping, was not in such a hurry as his subordinates, but sat on a Taishi chair, and poured tea for himself with a teapot in his hand!

After taking a sip of tea, he raised his head and first glanced around, and then said to the adjutant beside him: "Let them be steady in the past, what a hurry, the enemy's shells can't come over, give Lao Tzu to be careful and hit on time!" ”

The adjutant on one side hesitated a little, and said boldly: "But, didn't the boss say that let's shoot rapid fire?" ”

Tian Yaping said: "Even if it's rapid fire, it can't be like this, many of the brothers under this hand have not been playing the rear loading cannon for a long time, and it's not good to be busy and mess up!" ”

As he spoke, he glanced at his adjutant again: "You have to know, we are a test artillery battalion, and the devil knows how well these guns can withstand rapid fire, what if the gun barrel overheats and explodes?" ”

"It's not fun!"

As soon as these words came out, the adjutant beside him was scared half to death.

I was very excited when I watched the shelling just now, but when I thought that all the artillery in my experimental artillery battalion was test artillery, although they had already conducted live-fire tests before they appeared, and they had this kind of artillery for a month or two, and they had conducted many actual battles.

But in fact, in order to avoid accidents, the shelling is very conservative, especially the high-charge shelling and rapid fire shooting, to be honest, generally do not dare to do anything.

Because they don't know where the limit is, and if they break through the limit and cause the chamber to explode, won't it be doomed!

Even the arsenal did not know many of the performance limits of this artillery, especially the ability to withstand bore pressure and the data of the rapid-fire limit.

They also wanted to carry out limit tests, but this limit test often had to test the gun directly until it was blown up, and once it was blown up, a gun was lost.

And there are only six experimental artillery battalions now, and each of them is a baby bump, and it is not enough for combat, so why are you willing to take it to the extreme test.

That's why it's been dragging on!

However, this kind of slowing down is not slowing down too much, it is just maintaining the rhythm that has been tested in previous actual combat, and will not blindly increase the frequency.

Soon, the 75-mm guns in the experimental artillery battalion were already starting the second round of shelling.

This was followed by a third round.

Even if the pace was slowed down, the rate of fire of this steel rear-loading gun had already exploded the front-loading gun, and it didn't take a minute to shoot three shells.

The 75-millimeter guns in the experimental artillery battalion continued to bombard, and the only 150-millimeter short-barreled howitzer also maintained a continuous firing rhythm, although the rate of fire was not fast, but each shell was full of power.
