The fortress has several horns like stars, and the horns of the fortress stick out as a corner tower, which can be used to place muskets and cannons to kill and injure enemy troops from multiple angles from the front, side, and back.

The walls and corner towers of the fortress can form a flank shot, which greatly improves the defensive effect of the city wall, and is most suitable for giving full play to the long-range shooting advantage of the Southern Army.

Nurhachi saw this after watching for a while, so he ordered the second round to begin, half of the shield cart to cover the archers to shoot at the people on the corner tower, and the other half of the shield cart to push down the corner tower. When they reached the wall, half of the soldiers climbed the wall to attack, and the other half directly chiseled the corner tower with knives and axes.

It's that rough.

Jiannu has attacked the city before, often directly let the soldiers use knives and axes to chisel the city wall, it seems that this trick is very stupid, but often vigorously produce miracles, many earthen cities and fortresses in Liaodong are directly chiseled by them to enter the city wall.

Did Wang Hongyu expect it?

Of course it was expected.

Is there a special precaution in this regard?

Don't take precautions~

I hope Jiannu will do this.

When it was built before, it was nominally a small temporary prison, but in fact it was a small fortress. Wang Hongyu used a lot of civil engineering materials, but did not use a lot of rocks, so he didn't want to build strong.

Because I want Jiannu to dig the fortress~

At this time, the foundation of a corner tower had been chiseled, and Jiannu could chisel through the entire wall with no matter how hard he tried.

Chiseling and chiseling, people are constantly being shot in the back and in the side; Chisel and chisel, and when the weapon is chopped down, pick up the weapon in the hand of the corpse and continue to chisel.

Finally, in the fourth round, it's about to be chiseled!

"Roar!"

"Yay!"

The Jiannu roared happily, and the momentum of the Ming army was almost suppressed by them.

"Don't be impatient!"

Wang Hongyu reminded everyone to cheer up, because the surprise is coming.

A tall soldier with a bare head and small pigtails picked up a big axe and slashed hard!

"Boom!"

The last section of the wall in the northeast corner of the bastion was chiseled open.

The Jiannu lined up in battle formation and prepared to charge. Because as a rule of thumb, if you dig through the wall, you're the enemy.

"Boom!"

The big axe Jiannu struggled to open another opening.

Some of the Jiannu directly drew their bows and shot into the cracks.

Some arrows also flew out of the cracks, and several people were shot down.

"Kill!"

The slaves were furious, and more people shot into the cracks, and more arrows flew out of the cracks.

"Smash the wall!"

The rest of the people who didn't shoot arrows all wielded their weapons and chiseled the wall together, and finally a big crack was made in this section.

"Kill!" The slaves shouted.

"Kill!" The same thing was shouted from the other side.

Rush up and kill!

In the darkness, Jiannu mingled with another group of people.

Both sides are heavily armoured, and they are both very fierce and good at fighting, and they can't beat each other in hand-to-hand combat, which they are usually best at.

"Strong! Come and help!"

The other side shouted the same thing again.

The same words?

Some Jiannu felt that something was wrong, why did the one on the other side of the wall also shout Manchu?

"Wow!"

"Roar!"

shouted indiscriminately to communicate in Manchu, and found that the other side turned out to be his own person!

This side is the blue flag, and the opposite side is the white flag.

After chiseling the wall just now, it was all their own people who were beating their own people~

This is the mystery of the fortress that is difficult to beat~....

Attacking the walls of the bastion will encounter several corners sticking out, shooting at the flanks and back.

Attacking the corners of the fortress, whether it is climbing the wall or chiseling, blowing through, or blowing up, is of little significance~

Because the horns of the fortress are sticking out, even if you knock it out, you can't get into the fortress. Especially for the Jiannu wall, which chiseled through a corner, the back of the wall was only sticking out of the back of the corner, not in the fortress at all.

especially

It's dark, Jiannu is more reckless, chisel through the wall to hit, I didn't expect that the opposite side of the wall is also their own people~

The people with the blue flag and the white flag finally communicated, making sure that they were their own people, but as soon as they stopped, the top of their heads lit up.

The corner tower at the northeast corner of the bastion was chiseled, but there were still people on the section of the wall that connected the bastion.

The people above were of course the Ming army, and at this time they immediately threw down several large bamboo baskets from above.

The big bamboo basket was so black that I couldn't see it clearly, so I could only be sure that it contained something, and when I reached out and touched it, it was quite prickly.

"Tribulus terrestris! Tribulus terrestris tied to the bamboo basket!" Youjiannu knew what it was.

"Fuel tank!"

After throwing the big bamboo basket, the Ming army threw down a bunch of clay pots on the wall, fell on Jiannu's face, and reached out to touch the oil.

"Shoot!"

A few Jiannu archers immediately released their arrows, and smashed the oil canister in mid-air, directly scattering the crowd in the face.

"Set fire!"

In the end, the Ming army threw down a bunch of torches~

"Boom, boom!"

Bamboo basket explosion! Tribulus terrestris flies everywhere~

The oil ignited instantly, and Jiannu was on fire~

A large number of Jiannu gathered here, crowded one by one, and just figured out that the opposite side was their own people, and they had not had time to retreat.

Now you don't have to go, it's so happy to "dance" and "cheer and jump" together~

This made Jiannu lose hundreds of people, and also caused a very shocking visual effect, the Ming army was greatly encouraged, and Jiannu's momentum directly declined.

When Huang Taiji and Mang Gurtai saw it, they hurriedly let their two flags retreat.

This time I retreated relatively early, and the white flag and red flag in the back have not yet rested.

However, the yellow flag is in the northwest of the fortress, and the offensive is still fierce.

So there was a gap on the northeast side of the fortress.

"The cannon is in place!"

Li Tiezhu, the uncles and nephews of the Lu family, and the gunners of the Ming army pushed the four iron-core bronze cannons out of the fortress.

The chariots of the Zhejiang soldiers were also pushed out together, and they lined up in a half circle with arquebuses and Franc machines to carefully protect the gun positions.

Wang Hongyu estimated the time, and estimated that there was a gap of half an hour, provided that the two flags that Nurhachi did not forcibly order to rest would be on now.

"Boom~"

Three cannons rang out from the northeast, and Jiannu's cannon opened fire again, two of the three shells higher, and one hit the wall of the fortress, opening a hole that was not too big or small.

"Time is limited, take out the enemy's artillery!"

"Yes!"

Zhao Hannian, the commander of the Zhejiang soldiers, had already observed the position of the enemy's artillery, but he was unable to counterattack because he couldn't reach the Franc machine in his hand.

Now, the iron-core copper cannon is raised and aimed at the direction in accordance with the direction of the Zhejiang soldiers.

"Direction calibration, 2 miles and 75 steps away!"

"The direction is accurate, the muzzle of the gun is shaken high, and the distance is 2 miles and 75 steps!" The uncle and nephew of the Lu family have no other skills, and they have a lot of experience in the casting and aiming of cannons, and because of the artificial cannon for Acebanya, they know the geometric principles and know the flight trajectory of the cannonball.

In addition, Wang Hongyu clicked from it, and even Li Tiezhu learned some from them.

This, of course, can crush the captured Ming gunners on the opposite side!

The ammunition has long been loaded.

"Put!"

Wang Hongyu roared angrily.

Li Tiezhu, the uncles and nephews of the Lu family, and the gunners lit the fuse.

"Boom Boom Boom~"

Four cannons rang out, and four shells flew over.

"Boom !!"

The ground shook like a loud bang, and a violent explosion occurred in the Jiannu camp in the distance, and a huge fire rose into the sky.

Snow Leopard missiles
