Hearing the news, fifty artillery pieces will be added, and the generals' spirits are lifted, Xu Jin said:

"Deputy Marshal, it is rumored that the Changsun Army has been equipped with the Tianwei General Cannon, which can shoot sixty-three catties of projectiles at the heaviest, which is indestructible, and the adobe city wall will collapse with one blow, when will our army be able to build such a heavy artillery."

"This matter can be explained to you, the so-called Tianwei General Cannon of Changsun Guo was not made by him, but from a heavenly ship twelve years ago, and it is precisely because of this heavenly ship that artillery and black powder flowed into my Central Plains.

With such heavy artillery, Changsun Guo only obtained a few, and with its strength, it could only imitate artillery below 23 catties, and could not imitate 41 catties and 63 catties of heavy artillery, so there were not many Changsun heavy artillery.

As for our army, it's not that it can't be built, but the cost is huge, and the waste is amazing, casting ten such heavy cannons, and it is God blessing to be able to use two or three, so we don't cast heavy artillery for the time being. ”

"And such things, according to the deputy marshal's words, could it be that the Heavenly Ship Country can be more powerful than my Central Plains?" Xu Jin hurriedly asked.

Bai Liyan waved his hand:

"This matter will be left for later, and this time I will only talk about the current war situation, and I will not discuss the matter of the heavenly ship. The newly cast 50 guns were 12 and 18 catties, each with 25 guns. A new artillery array will be used to siege the city, and the effect will be more than five times greater than before. General Ye Xin. ”

"The end will be."

"Tomorrow the artillery of the general will be pulled to the south of the city and deployed one mile away, and the defenders of the south gate wall will all withdraw before the shelling tomorrow, and the people within three miles north of the south gate will be evacuated, and no one will be allowed to hurt the innocent."

"Deputy marshal, is this going to bombard the city?" Ye Xin was surprised.

"Exactly, the new method of warfare needs to be effective and effective. After the new artillery arrived, it was time to attack the rebel city. ”

The grass mud bag is not a universal body armor, even if it is a bulletproof steel plate, it can't resist the repeated bombardment of the dense barrage.

The principle of the grass mud bag is to use the grass woven bag to fill the soaked soil, so that it can be hung on the city wall to absorb the physical impact from hard objects, so as to achieve the purpose of protecting the city wall.

Conventional catapult attacks are limited by the angle and accuracy of their shots, and the probability of hitting the city wall is the lowest ten, with more than half of them falling into the city and the city's head.

After the appearance of artillery, it was limited by the direct aim of artillery, and usually used a row of guns and small elevation angles to bombard, so that most of the projectiles could be concentrated in the front of the city wall, but the accuracy was not satisfactory. And more often than not, solid projectiles are more of an intimidation and morale killing, and the actual combat effect is not obvious.

To do this, it was necessary to readjust the artillery position, so that the projectiles scattered in various places could concentrate on attacking one point.

A series of orders were issued, and Baili Yan inspected the army of Lintai Xianjun and the local people non-stop.

The total population of Lintai city and the villages and counties under its rule exceeded 110,000 people, 70,000 people from Sun Guo, and the rest were people from Xu State and Zhiguo.

However, it is still difficult to eradicate the cancer of the cult in private, and although the Xianjun distributed a large number of leaflets, the results were not ideal; on the one hand, the literacy rate, and on the other hand, the backwardness of cognition.

The next day, Ye Xin ordered someone to pull the artillery one mile outside the city and hand it over to the armed battalion. The first batch of cast guns totaled 10 6-pound guns, 10 12-pound guns, and 5 18-pound guns, according to the weight of the projectile, the firing range, and the three types of guns were configured in vertical echelons before and after.

The artillery landing point was calculated, and it would eventually hit 500 paces north of the south gate, within the width of the front of the city wall and the height of 7 zhang.

Seeing Bailiyan deployed like this, Ye Xin couldn't help but worry and said:

"Deputy marshal, with such a front and rear cannon, I'm afraid the rear cannon will hit the front cannon."

"General Ye really thinks so?"

Bai Liyan asked rhetorically, and Ye Xin said seriously:

"The projectile flew out at a very low altitude, and it took time to hit the former. The artillery officers who went to the armament battalion for training have always been lined up with guns, and there has never been a front and rear guns. ”

"That was in the past, Ben Hou did not expect that there would be so many drawbacks in the artillery siege, so the artillery skills of the military battalion were superficial, and after getting the news, he readjusted the tactics, and now it is a new style of warfare, as long as you do it according to the order, there will be no problems under normal circumstances, General Ye can rest assured."

Affected by the inherent shortcomings of direct aiming at small elevation angles, before the advent of curved overhead shooting, direct aiming at flat fire or direct aiming at small elevation angles was usually fired in a single formation, that is, all guns were fired in a line.

The longitudinal echelon configuration artillery is affected by the equal horizontal plane, and the front and rear guns are roughly in a horizontal plane, which inevitably leads to the rear artillery due to the small elevation angle, and the projectile hits the front gun position.

For this reason, hills and heights are usually selected as the deployment site of direct-aiming artillery, and the artillery is arranged in echelons up and down, and the plane is staggered, so that when the vertical artillery fires, the projectile crosses the front artillery position, and thus flies over the battlefield.

For example, if deployed on flat ground, the front and rear artillery are arranged in an inverted triangle, the light artillery is fired flat in front, and the heavy artillery is slightly raised in the rear, and the heavy artillery is at least 100 paces to one mile away from the front due to the influence of caliber and range.

Of course, the principle is actually very simple, but it is not easy to do, and it requires a certain amount of kinetic mathematical calculations and physical cognition. It is impossible to master the more complex shelling techniques by relying only on the simple firing meters that have been formulated.

At this time, Su Hong and Bai He commanded the artillery section of the armed battalion to set up a position to load artillery, and inserted two logs more than one person high in each of the six-catty guns and twelve-catty guns in the front row as a reference.

When everything is ready, Jiang Jie will report:

"Deputy Marshal Qiqi, Zhuyuan calibration is complete!"

"Order Su Hong, six catties and twelve catties of running personnel to evacuate, eighteen catties of cannons, three rounds of calibration of each cannon, and fire freely."

"Yes!"

The eighteen-pound gun is at the rear, and the reasonable setting of the gun position and the configuration of the parameters of the elements theoretically do not have the probability of threatening the artillery position in the front.

Of course, even if the breech gun is used in the powder bag, it is still the best gun, if the gunpowder is soaked in moisture and water, the ammunition is incapacitated, the power of the gunpowder is insufficient, and the projectile may still fall on their own heads after being disemboweled, especially on rainy days, this situation is more frequent, but people can not always consider the worst side, and the way is always more than difficult.

At this time, the order was transmitted to the position, and the six-pound artillery and twelve-pound artillery were evacuated one after another, leaving only the last row of eighteen pound guns being ignited, and all the officers and men of the armed battalion were located behind the artillery position, and the young men were in the front, watching the artillery training with their eyes on it.

After a while, a cannon rang out, and everyone's feet shook, and the projectile roared out. Due to the slow muzzle velocity, the projectile climbed rapidly at a speed visible to the naked eye, leaped over the 12-pound artillery position in the front row and was 30 steps above the ground stakes, and then quickly crossed the six-pound artillery position and flew towards the city wall of the south gate of Lintai.

Several muffled sounds were heard, and a puff of gray smoke could be seen, and three of the five shells hit and two missed. Su Hong quickly trimmed the gun position and fired the second time, and the effect was immediate, and all five shots fell into the target position.

Ye Xin was overjoyed when he saw this, and hurriedly said:

"Vice marshal, it's really a god, the iron pill can fly over the top of his own head, as if he has eyes, and it is extremely accurate."

"This is the method of counting, as long as you master this method, in fact, everyone can do this. General Ye, you see, Ben Hou now ordered twenty-five cannons to be deployed in front and rear, so that he could attack a little.

When the fifty artillery pieces arrive in the future, and use them so intensively, only bombarding one city wall, the Black Turban Army will hang up more logs, grass and mud bags, and how can it resist the bombardment of our army with 75 iron pellets at a time. In addition, our army bombarded the air with hot air balloons, and where the artillery bombardment, how could it have the power to parry. ”

Defensive soft armor made of wooden mud and straw bags is not a panacea, it can only withstand sporadic and unrepeatable bombardment, and under the intensive bombardment of artillery, the same crater is densely loaded in a short period of time, and even steel will be smashed through.

At the same time, with the bombing of hot air balloons, it can completely suppress the counterattack of the defenders above the city wall.

After the three rounds of shelling of the eighteen-pound cannon were over, Baili Yan ordered:

"Jiang Jie, order Su Hong, all cannons are in place, five rapid fire!"

"No!"

At a short time, the six-pound and twelve-pound guns opened fire one after another, dozens of projectiles poured into the target area, leaving dense craters, and the adobe city wall gradually cracked one after another, and if the bombardment continued for a day or several days, the city wall in the target area would undoubtedly collapse.

"General Ye, do you think it's so powerful, with 25 cannons of 12 catties and 18 catties each, can the city wall be destroyed?"

"Back to the deputy marshal, with such power, it should be possible."

"General Ye, tomorrow you will gather the cavalry and go to Gongcheng and Yin Qu with Ben Shuai to explore the truth."

"Yes!"

As soon as the words fell, Guan Longxiang said on one side:

"I'm afraid that the news of the deputy marshal's coming to Lintai has already been leaked, and he only used cavalry to go out of Gongcheng, Yinqu and other places, for fear that he would be detected by the supernatural rebels, and set a trap to ambush the deputy marshal, and he should bring more soldiers and horses."

"Hehe......" Bai Liyan waved his hand disappreciatively: "This marshal is not going to lead the army to fight, but to explore the reality of various places, and leave after seeing it, without stopping, Mr. Guan Long only needs to sit in Lintai with Mr. Zhao, and there is no need to worry." ”

"But the deputy marshal is no longer a vanguard general, and he is concerned about the safety of the whole army, so he left the camp rashly, which is probably inappropriate."

"Ben Shuai has his own opinions, and Mr. Guan Long doesn't need to persuade him anymore."

Surveying the battlefield and being familiar with the terrain is the basic military principle, and when you first come to Changyin County, you can't intuitively understand the local geomorphological characteristics just by looking at the so-called topographic map of mountains and rivers.

Gongcheng, Yinqu and Zhaocheng take Yinqu as the fulcrum, forming an obtuse triangle, Gongcheng and Zhaocheng are relatively far away, and the Shentong Heavenly King will hoard the main force in the northwest outside Yinqu, it is to facilitate the mobile reinforcement to Gongcheng and Zhaocheng.

There are many defenders in Zhaocheng, west of Lintai, and it is not the main attack direction of the Xian army. The main direction of attack of the Xian army naturally fell on Gongcheng and Yinqu, and only by opening up the two places could they go north to Ganfu and attack Xiaguan in the east.

The supernatural power is to grasp the mentality of the Xian army to seek closeness, put down the character of the defense, and focus on the defense of the eastern flank, so that the Xian army can not break through. In order to break this situation, in addition to attacking the heart, the strategy of the Xian army must be adjusted at the same time, and military pressure and political bribery go hand in hand, breaking the defensive structure of the supernatural king.
