At the same time, Liu Zhiyuan and Geng Zhongming also launched a crazy attack on Lushun Fort. Unfortunately, Lushun Fort was built strictly in accordance with the regulations of the Ming City, three meters high and one meters thick. In addition, the newly built castle in Baiyu Mountain, the Tiger Tail Bunker, and the warships on the wharf formed a multi-in-one three-dimensional defense, and Liu Zhiyuan and others faced greater difficulties.

The Qing Dynasty could only attack from the north of the castle like Bo and Tuo. After repeated setbacks, they had the idea of ​​building artillery positions on the north mountain. Unfortunately, they had no chance to build safely and steadily under the attack of artillery at the head of the Lushun Castle. If the construction is far away, it will not work.

A month later, they worked hard to transport the cannon of ten thousand kilograms from Liaoyang. Unfortunately, they encountered the plum rainy season in Liaodong again. The rainy season was continuous, and the cannon of ten thousand kilograms was lying on the road and could no longer move.

After the rain and the sky was clear, I finally got it and was busy transporting it to the vicinity of Lushun Fort, the twelve pounds of Nibuchu bronze cannon that had basically not been moved in the city these days began to show its power.

It has been said before that the effective range of the 12-jin Nibchu bronze cannon is four miles (at an octave elevation angle on the flat ground), and the range on the city wall is even longer. The actual range of the 10,000-jin cannon, which was known as "one gun is decayed for dozens of miles" in the Qing Dynasty, was similar to that of the Nibchu bronze cannon, but the shells loaded were larger.

It is this kind of cannon. After they went south in history, they successively destroyed Tongguan and Yangzhou City, but unfortunately they met an opponent at their doorstep.

Under the storm of the twelve-jin Nibchu bronze cannon, they had no chance to get close to the effective range. They could hit the city wall even if they raised the elevation angle from far back. Unfortunately, they were already at the end of their strength and did not work at all.

So, the two sides became stalemate near Lushun Castle, and no one could survive.

With the Hanhai Army's most advanced artillery and muskets, and multi-in-one cross-fire power, Lushun Fortress and other fortresses were nailed to the ground like nails, and the enemy was basically nothing.

Not to mention Lushun Fort, my eyes turned to Guanjie Fort, where Luke Dehun had guerrilla wars with Ye Duo across the Second Songhua River.

A few years later, Ye Duo has been promoted to commander of the brigade, and Luke Dehun has replaced Nikan (Aisin Gioro Nikan) as the garrison general of Longcheng, while Nikan has become a general in Sarhu and Xinbin Castle in the upper reaches of the Hun River.

However, the guard general of Guanjie Fort became Tazhan's son Ai Xing.

The general of the Hanhai Army in Jiapigou confronted Guanjie Fort across the Songhua River became the dignified commander Ensuo himself.

It is definitely better to go up and down.

After passing through Yangguli and Tazhan two generations of genuine Batulu, although the Aixinga generation has maintained the tradition of bravery, it cannot be compared with the days when they lived in deep mountains and forests with bears and tigers. Therefore, both bravery and military command ability are ultimately inferior.

But Ai Xing'a is still above the level. Otherwise, in history, when Duoduo fought with Huang Degong at the city of Chizhou, he would not have been able to capture Emperor Hongguang first.

What's more, Guanjiebao (Huadian City) is just a frontier position after all.

A Ling Fort built according to the Portuguese suggestions, the main fort can be stationed with 300 troops, 200 auxiliary forts, and 500 people. This is the total force of Guanjie Fort.

After Ensuo arrived with his army, he had enough time to launch an attack. After Ye Duo took the Tonggou Fort, all the outer auxiliary forts of Guanjie Fort were cleaned up.

Only the five-pointed star-shaped main castle is left.

The outer periphery of each big horn is another parallel big horn, and that is the auxiliary castle.

After occupying the auxiliary fortress, Enso built a position southwest of Guanjie Fort to prevent the Lukeshun from sending troops from the Dragon City to rescue him.

Unexpectedly, to this day, since Guanjie Fort is still in the hands of Ai Xing'a, Luke Dehun actually became extremely superstitious about the defense of this Fort.

"Even if there are thousands of troops, it is difficult to break."

This is his idea. What's more, Longcheng is the most important military base in the northeast of Liaodong, and it cannot be easily lost. If he is hit by the barbarian thief and lures the tiger away from the mountain, it will be no more worth the loss. What's more, Guanjie Fort is important, it is only the outpost of Longcheng, with only 500 people.

Longcheng has stationed 5,000 elite Manchurian Eight Banners!

Enso was extremely depressed when he saw that Luke Dehun was not deceived. Seeing that his subordinates had begun to make achievements one by one, he led his army but was unable to achieve his strength under the small castle. This was unreasonable.

So after waiting for a while, the official attack of Guanjie Fort immediately started.

At this time, Ai Xing'a knew the true strength of Han Haijun.

In one day, all the auxiliary forts around Guanjie Fort fell.

This is because, unlike other routes, Enso, who is the commander of the Changbai Mountain Legion, also has a completely established artillery team, including Nibchu bronze cannons and short-barrel cannons.

Therefore, when the terrifying loud noise of the Nebuchu bronze cannon came out, Ai Xinga in the castle couldn't help but turn pale.

The same is true for Fernando.

He was originally invited by Sun Yuanhua to train his gunners and musketeers. Unexpectedly, before he arrived in Denley, the Denley Rebellion led by Kong Youde occurred. In the end, he was swept to Liaodong by Kong Youde, along with dozens of other Portuguese people.

After arriving in Liaodong, Huang Taiji did not treat them unfairly, asking them to assist in the creation of artillery and muskets, and also helped train the Wuzhen Chaoha army headed by Ma Guangyuan and Shi Tingzhu.

When the Qing Dynasty and Xia State confronted each other in the Changbai Mountain area, Fernando suggested building a Lingbao on the basis of the Guanjie Fort Original Fort. This time, the Qing Dynasty agreed to his suggestion and after it was completed, he would serve as the deputy general of the fort. At first, he was the deputy to Luke Dehun, and later he attacked Ai Xing'a.

The low, heavy, long and loud noise made by the twelve-jin Nibchu bronze cannon when it blew, even the veteran who was nearly forty years old this year, who had participated in many battles between the Portuguese and the Dutch in India, Malacca and Macau, and had a very rich experience.

As a gunsmith in the harbor city of Estoril near Lisbon, Fernando is very sensitive to the sound of guns. Of course, they are all obtained based on short-barrel guns. Cannons, especially the new cannons, are not even the British who have studied artillery most thoroughly in Europe.

Their carrier-based cannons still have not gotten rid of their silly, big, fat and thick virtues.

In the telescope, the body was not thick, the yellow-green cannon body, two wheels that were obviously wrapped in iron or were made of iron, and the heavy gun mounts that absorbed the back of the cannon were fully visible.

"What kind of artillery is this?"

Of course, the blacksmith Fernando, who appeared in the late 18th century, could not understand such artillery, which appeared in the late 18th century.

"Old Fei, think of a solution now."

He grabbed his shoulders hard, yelled in his ears, instead taking out a cigarette.

After trembling and igniting, he took a sudden breath. His somewhat busy mood seemed to have improved.

what to do?

He was thinking too.

Destroy this cannon is of course the choice, and that is not in line with the original intention of building the Lingbao. Moreover, there are only a few hundred people in the fort, and there are probably at least a few thousand "barbarian thieves" outside.

"Battle thief?"

While swallowing clouds and spitting mist, Fernando smiled bitterly. He held the flintlock rifle that is rare in Europe now. With this strange sound, the powerful artillery cannon can still be "barbarian thieves?" If so, then the whole of Europe will be barbarian thieves, and the Qing Dynasty and the Ming Dynasty are even more barbarian thieves among barbarian thieves.

After a while, he finally settled down.

The so-called diamond castle, the most important feature of a real diamond castle is not only the strange shape that makes it easier to face the enemy with more and fight less, but also an important feature is that the diamond castle is very thick!

Like the large and small diamond castles built by the Spanish in the Philippines, if Han Haijun had not taken advantage of the opportunism and wanted to break the attack in a dignified manner, it would have been a purely fantasy. The walls of Santiago Castle near Manila reached ten meters in thickness.

The ten-meter-thick city wall could not be broken even if the Urban cannon came.

At present, this Guanjie Fort is naturally not as exaggerated as Santiago Fort, but it has reached a thickness of one meter. Both sides are made of ancient glue-conjugated agents such as stones mixed with glutinous rice, egg white, etc., and there is only a layer of rammed earth in the middle.

After the solid bullet shot from the strange cannon hit the city wall, although the sound was terrifying and the people in the castle were frightened, except for some dust falling, the castle structure was not damaged.

Fernando also took a closer look at the shell that was shot.

"About twelve pounds"

After smoking the cigarette, he stood up. He smiled and said to Ai Xinga, who was depressed, "Well, don't panic, the cannon of the barbarian thief cannot crush the city wall."

When he saw Ai Xing's face cleared a little, he also said something meaningful.

"I am just a mercenary. Although you give me a high salary, I will eventually be a mercenary. How to fight, I will eventually listen to you."

Ai Xing's teeth were so annoyed when he heard this.

"God, the emperor treats these Westerners so well, and his monthly salary is as high as fifty taels, and he can't win the hearts of these ungrateful wolves?"

However, since Fernando said that the barbarian thieves could not break the wall of the Lingbao City, his messy heart could finally take a break.

Early in the morning.

At night, Guanjie Fort was lit up at the top of the fort in order to prevent the attacks of barbarian thieves, a large number of torches were lit on the top of the fort, illuminating the surroundings of the fort as if they were day.

Except one place.

Guanjie Fort is located in a large bay on the Huifa River. The Huifa River spread a large bay of almost 270 degrees before winding towards the northeast.

In the package of this great bay, a peninsula of about three miles was formed, and the Lingbao was built on this peninsula.

In other words, if the enemy wants to attack, they can only come from the narrow part connected to the continent in the north, and the originally concave auxiliary fortress has now fallen into the hands of the Hanhai Army.

In summer, the Huifa River is abundant, and the river is about one mile wide. The barbarian thieves did not drive ships, so the defenders in Lingbao were restless.

Therefore, the focus of their vigilance was the concave auxiliary castle they built on the north side, which was the only place where the enemy could appear in large quantities.

On the river surface, the originally calm river surface suddenly had a little turbulence, but the soldiers standing on duty on the fort would not notice it. If they were equipped with a large number of telescopes and kept staring at the river surface, they could still find some clues.

On the river surface, with the waves appearing, many protruding tiny things appearing on the water surface, those things are thin and about one foot long.

Not long after, a black figure came ashore. The man carried a package on his back, obviously wrapped in multiple layers of tart cloth. The man spit out the thing in his mouth - it turned out to be a curved thin bamboo tube.

After carefully looking around, the man stood under the corner of the Lingbao, which was a place that the soldiers on the fort could not see, about one foot wide.

"Quagua"

The man imitated the frog's cry - the sound of Huifa River was everywhere at this time.

Soon, about nine people dressed up like him went ashore. With his wave of his hand, these people untied the packages on their bodies. Now they finally saw clearly that in addition to the things wrapped in tart cloth, there were also short-handled shovels.

After observing the movement again, the ten people touched the depths of the Lingbao and soon disappeared into the darkness.

About half an hour (half an hour), a series of shocking loud noises rang out on the banks of the Huifa River. After the sound, the originally thick and solid Guanjie Fort had collapsed by more than half.
Chapter completed!
