With the instructions from the artillery surveying and mapping station, the gunners of the heavy artillery battalion began to shake the rocker and adjust the muzzle according to the data sent back from the artillery surveying and mapping station.

I saw the black cannon slowly start to descend as the swing arm rotated.

This time, the main force of the Ming army's artillery was placed in the north, because only this place could the Ming army's artillery be placed.

In order to capture Constellation Danteburg, Cao Bianjiao mobilized all the artillery he could mobilize, including the cannons that had just been transported from the naval transport ship.

Two artillery divisions, more than a thousand cannons, were ready to be in place, and artillery formations were carried out one kilometer away from Constellation Danteburg, and eleven artillery positions were arranged.

The smallest of them were artillery more than one hundred caliber. In order to be able to break through the walls of Constellation Danteburg, Cao Bianjiao specially mobilized the two heavy artillery battalions left here by His Majesty.

Twelve 155mm caliber howitzers formed a heavy artillery battalion. More than 2,000 soldiers from the Ming Dynasty served twelve heavy artillery, which could be said to be a corresponding gun for two hundred people.

There is no way, the weight of these 155-caliber heavy artillery is really terrifying. Anyway, transportation is the biggest problem for the current Ming army. Even if two hundred people serve one cannon, it is only a matter of playing. Fortunately, Zhu Youxiao equipped these cannons with trucks, otherwise it would be really difficult to transport them.

A shell weighs more than 90 kilograms, and a person can only carry one shell, so a truck must be used.

If you want to use the truck, you must have a road that allows the truck to run. Two-thirds of these more than 2,000 soldiers were responsible for building the roads, so that you could barely transport these twelve 155 heavy artillery to the city of Constellation Danteburg.

In addition to these twelve 155 heavy artillery pieces, Zhu Youxiao also left eighteen 122 howitzers.

Because Zhu Youxiao had long anticipated that Constellation Danteburg's attack would be difficult. In order to prevent huge casualties from the Ming army and to prevent the Ming army from spending too much time in this place, he could only leave his treasured heavy artillery.

Zhu Youxiao also told Cao Bianjiao not to use these cannons when he did not encounter a particularly difficult city to break, but he could use it when he attacked Constellation Danteburg.

After all, Zhu Youxiao has heard of the famous figure of people and the famous name of Constellation Danteburg.

At this time, the soldiers on the city wall opposite were also staring at the artillery group opposite with horror. They were so dark that they looked all of them, all of which were black muzzles of cannons, and even the pieces of cannons could be seen without using a telescope.

The guardian Apshire, who was guarding this section of the city wall, held the telescope and his hands were trembling.

To be honest, it was the first time in his life that he had seen so many artillery, which made him feel his heart and soul thrust.

At this time, more than a dozen hot air balloons rose from the Ming army camp, and a hanging basket was hanging from the hot air balloons.

There were two Ming soldiers inside, one holding a telescope to observe the situation in Constable Danteburg, and the other was responsible for manipulating the direction of the hot air balloon.

In the air of 300 meters, it is impossible to say that Constellation Dantemberg is seen in his eyes, but he can also see clearly the situation on the city defense.

With this surveying and mapping balloon, you can accurately know the bombardment effect of the artillery, and then find out the weaknesses of the enemy's city defense for targeted bombing.

However, although the Ming army had hot air balloons, they were only used for surveying and mapping, and did not use this hot air balloon as an attack weapon.

First of all, the hot air balloon has risen by only more than 300 meters. Zhu Youxiao has also conducted experiments on this height, and there are still some means to knock down the hot air balloon.

Moreover, the load load of this hot air balloon is not high, and it also requires a good wind direction and has high requirements for the weather. For the Ming army at this stage, the observation ability is greater than the combat ability, so it is not used as an attack weapon.

Anyway, it is impossible to really get the air force out of hot air balloons. Unless you create airships, you can form an air force.

However, the technology mastered by the Ming Dynasty cannot make airships, so Zhu Youxiao’s air force can only be an idea for the time being.

All data have been marked under the observation of the surveying and mapping balloons, and the artillery below has also obtained their targets. Now that everything is ready, we are waiting for Cao Bianjiao to order.

After Cao Bianjiao, who was at the front line command center five miles away, received a report from the General Staff, raised his arm and looked at his watch.

"Staff General Lin! Send a signal! Attack!"

With Cao Bianjiao's order, Staff Lin ran out, then took out the starting gun and pointed it at the sky and pulled the trigger.

"Take!"

A red signal flare rose into the sky.

This is the signal of attack. The artillery soldiers have been waiting for these signals for a long time. After seeing the signal, the small red flag in the hand of the commander on the artillery position suddenly waved forward, and then roared hard.

"fire!"

If the momentum can be realized, you can see the three-foot war fire spurted out from your mouth when the artillery commander roared out of his gun.

"put!"

The first to fire was the 155 Howitzer Battalion. When the gunners pulled the ropes, the cannon suddenly let out a roar. The dust around them suddenly flew up, and the huge recoil vibrated and the ground trembled suddenly. Even the ground recoil caused by the powerful recoil could be felt more than ten meters away.

Twelve shells flew straight towards the city wall, and then they saw twelve huge fire balls bursting out from the city wall.

This is a 155mm cannon from later generations. Such a large caliber is also a heavy cannon in later generations. You can't escape half a football field with one shot, and you can't even get rid of it within a radius of more than ten meters.

The shell hit the city wall, and the original good city wall was blown up by the shell. The small one was one meter wide and the large one was enough for a carriage to enter and exit.

Although the city walls built by the Ottomans were strong, they were obviously not enough to see under this heavy artillery.

Of course, these twelve heavy artillery are the most powerful, but it does not mean that other artillery is not good. I saw bursting flames everywhere on the city wall facing the Ming army, or gravels flying around by solid artillery shells.

"Swish! Boom!"

"Bang! Boom! Bang!"

The guard Apshire shrank under the city wall. Facing the terrifying artillery of the Ming army, he did not dare to emerge, and hugged behind the city wall like a coward.

But when the shell hit the city wall, he could clearly feel the city wall trembling, as if it would collapse the next moment.

This terrifying and dense artillery made Apshire lose his walls.

Originally, he had a strong city wall because his city wall was very strong, but now he faced the Ming army's artillery and realized that the current solid city wall was useless.
