On the battlefield at the end of the Ming Dynasty, the Francophone cannons and red-coated cannons used by the Ming and Qing armies were basically copied from the Western ship-based guns, not real land artillery.

The artillery unit of the Chu army had just been established, and the Battle of Xianning was her debut, although she tried her best to do her best, she was still a little jerky at the beginning.

The artillery position was 600 meters from the city gate, and in the first test fire only two guns hit the target, and the other guns were crooked. Chen Shangwu was not very satisfied with this result, so he personally went to each gun position and double-checked and calibrated with the gun commander, hoping to be more accurate when the attack was officially launched.

"It's just a test shot, it's nothing if you can't hit it accurately, we'll see what you can do later!" Chen Shangwu encouraged the artillerymen while aiming at the Portuguese artillerymen next to him, their six-pounder guns were bulky, and they had just been placed on the gun emplacement, preparing for a test firing.

Chen Shangwu did have the mind to compare, only two of his twelve cannons hit the target, although it was a test shot, but in front of tens of thousands of Chu troops, he still couldn't get down in face. Most of the Chu army did not understand artillery, and there was no concept of test firing at all, and when the artillery was fired just now, all battalions let out a burst of cheers, but when they saw that several cannons were completely flying, the cheers immediately stopped again.

"It is said that the Francois are good at using firearms, see if they can hit the ......" Chen Shangwu's heart was turning this thought, and the Portuguese soldier's six-pounder cannon suddenly fired.

"Bang! Whoosh! ”

Chen Shangwu watched the five-pound cannonball fly towards the Xianning city wall, just as it hit the city tower, the huge kinetic energy blew the masonry wall into countless pieces, several Qing soldiers flew flesh and blood, the battlements of the city wall made of bluestone fell down like a building block, and one end of the roof fell on the city wall. Immediately a cloud of smoke and dust rose up.

This cannon actually destroyed most of the city tower!

On the city wall of Xianning, Xu Bin and that Aliha Chaohazhang Kyoto were dumbfounded, looking at the ruined city tower and stunned, if they still stayed inside, this time it would definitely be more auspicious!

"Nanban has a cannon!" Xu Bin pointed in the direction of the six-pounder gun, and bit the word "big" very hard, hundreds of meters away, he couldn't see the appearance of those Portuguese soldiers clearly, thinking that they were also ordinary Ming soldiers.

"Don't be afraid, this cannon can destroy the tower. But you can't break the city walls! "Aliha Chao Hazhangjing knows very well that the city tower is just a house built on the city wall, no matter how strong it is, it can't withstand the bombardment of the six-pounder cannon, but it doesn't matter if the solid city wall is more than one zhang thick. Even if it is repeatedly bombarded by a six-pounder gun, at most it will be broken a layer of skin.

"What about the city gates? The city gate will definitely not be able to bear it! Xu Bin was also a little anxious. The artillery of the Ming army is so powerful. The iron-clad wooden gates were afraid that they would be pierced with a single shot.

"Well, now you can only go out of the city to face the battle, and you must destroy the cannons of the Southern Barbarians!" In order to retain the passage out of the city to counterattack, Xianning City did not block the city gate, and Ali Hachao Ha Zhangjing also knew that the shape was in danger now, and there was only a field battle out of the city. Destroy the artillery of the Ming army, and Xianning can turn the corner from danger.

The two of them each passed down orders to gather troops and prepare to leave the city, and the Aleha Chaoha soldiers were all armored cavalry. Although there were only 500 people, it was the most important mobile force in the city, and all of them went out in this counterattack, and Xu Bin's green battalion soldiers were divided into two parts, half followed Aliha Chao Hazhangjing out of the city to fight, and half stayed in Xianning City to watch over the family.

The Qing army had already prepared for battle, and it didn't take a few minutes to assemble, ready to go out of the city from the south gate, and there were more than ten meters away from the city gate hole......

……

On the artillery position of the Ming army, the Portuguese soldier's six-pounder cannon opened fire for the second time, this time aiming at the city gate under the city tower, the shell weighing five catties whistled out, accurately hit the left side of the door, and then there was a loud bang, the city gate seemed to shake twice, but if you look closely, it is still standing there well.

The Chu army who was watching the battle froze all of a sudden, not understanding what was going on, and it took a while before someone shouted.

"Pierced! Pierced the gates! ”

The kinetic energy of the cannonballs was too strong, and the iron-clad six-inch pine gate was like paper paste, and a large hole was lightly broken, and the debris and wood were brought into the city gate hole by the cannonballs, and the Qing army behind the door was killed and wounded, and the Ming army stood a few hundred meters away, not seeing the process clearly.

"No. 1 gun, No. 3 gun, No. 5 gun, No. 7 gun, No. 9 gun, No. 11 gun, aim at the city gate and fight continuously, don't move the other artillery groups first." Chen Shangwu issued an order.

Chen Shangwu was a little unaccustomed to it at first, he preferred to use the sexagenary branch to number, but in the actual exercise, he gradually discovered the benefits of this kind of numbering, the command was clear and concise, and the command and control were flexible, which was clearer than the Jiashen cannon and the Yichou cannon.

With his order, one four-pounder gun, five three-pounder guns opened fire one after another, and this time the hit rate increased significantly, and after two consecutive volleys, seven or eight shells hit the city gates, and one shell happened to hit the suspended bridge that was hoisted high.

Chen Shangwu held a telescope and observed the results.

The suspension bridge in Xianning County was unexpectedly tough, and after being hit diagonally by a three-pounder cannonball, although it was broken into a small piece, it did not disintegrate and Yan zhòng deformed, and it seems that it can continue to be used, but the suspension bridge is very close to the city gate, and it was destroyed by the artillery fire of the Ming army sooner or later.

In contrast, the city gates that were hit by the focus were much more miserable.

The power of the four-pounder cannon was far inferior to that of the six-pounder cannon, and the power of the three-pounder cannon was half less than that of the four-pounder gun, but because it did not directly penetrate the city gate, all the kinetic energy had to be borne by the city gate, and the effect was not worse than that of the six-pounder gun.

There was a big hole in the door on the left side, and several shots were smashed in succession, and several large pieces had been broken, and it had basically been broken, and the door leaf on the right side was not injured at first, and it was relatively stronger, and after the shelling, there were two large cracks on it, but it still maintained its basic shape.

"Father, let the thirteenth cannon give another guy to the right door!" Chen Shangwu shouted to Father Qu Shawei, who was acting as the interpreter.

Qu Sha nodded slightly, and gave a few orders to the Portuguese artillery, the six-pounder gun adjusted the horizontal angle slightly, aiming at the right city gate, at this time, the two broken city gates were suddenly pushed open, and a group of Qing soldiers brandished knives and guns, shouting and rushing out.

At the same time, the Qing army in the city pulled the noose mechanism and slowly lowered the drawbridge.

"The Tartars are going to charge!" Chen Shangwu was like a wolf smelling blood, and shouted excitedly: "No. 2 cannon, No. 4 cannon, aim at the city gate and hit me!" (To be continued......)
