Due to the fighting of both sides, there seems to be no one on the wall of the trading city, but behind the wall of the stack wall, a lot of sentinels are lying. They look at the 10,000 thousand Ming Army through the stack of the stack.

He immediately rushed to Xiacheng to report to Yixin and Colonel Calzakov.

"At least 15,000 Ming Army entered the Russian territory ... It seems that the Ming Army has received news of the declaration of war!"

Colonel Calsakov quickly made a judgment. He guess this time it is likely that the Ming Army was proactively declared war! The Tsar may not know.

"Order the soldiers in the Northern Army Camp to retreat into the buying and selling city!"

Colonel Calsakov quickly ordered the company outside the city to retreat, but he didn't want to lose a company's strength in vain.

"Mr. Colonel, just let Ming Dogzi besieates the city?" Yi Xin also asked in the Command of Kalzakov. He asked unwillingly.

"Let them siege, the food in the trading city is enough for us to eat for a year, not afraid of surrounding!"

Yi Xin sighed, these foods are the rations of hundreds of thousands of flags and women and children! Although Muravitov promises to have enough rations in the village to prepare for the village to ensure that all of them are all people, to ensure that all of them are all people.

Will not be hungry on the way, but is there a bit of authenticity in this case?

"Mr. Colonel, willn't Ming Dogs just around?" Yi Xin asked a little bit.

"This is the case for the time being. I think the artillery battle just now should let them know that the buying and selling city fortress is terrible." Colonel Calzakov was a little proud.

If the Ming Army has a little Western military common sense, it will not attack a solid fortress, because such a castle can not be solved by corpses and bleeding! The correct way is to build parallel and transportation around the fortress.

Overlooking in the air. Just like a spider web. Wait until the project of parallel and transportation. The real shells will begin, and the enemy's infantry will gradually shrink the surrounding circle under the cover of the cannon ... "

In the urban defense command in the trading city, Colonel Calsakov expression calmly introduced Yixin the most commonly used fortress tactics in the West. He said: "This tactical name is parallel to attack the law one after another, which is the Wozang of France.

The Marshal invented in the invention of 1880 years. And our current defensive trading city is a Wo Bang -1 Castle, and it is also the masterpiece of the designer of the Worbon Marshal. "

"Mr. Colonel, can we keep it?" Yixin asked the question he was most concerned about. He was not interested in listening to Colonel Calsakov what he said is the Wo Bangbao and how to capture such edges.

Fort.

"His Majesty. Please rest assured! The buying and selling city is extremely strong and can be able to keep it." Colonel Calzakov still had no expression on his face. Only by constantly knocking on the map of the map station, he revealed his inner anxiety.

The Castle of the Trade City was personally responsible for supervision, and it was indeed a fortress that was difficult to be captured. But it was not unable to be captured! If he let him command the 60,000 new army with a large number of artillery, up to 4 months, up to 4 months.

The trading city will be broken by yourself!

The same as that of Colonel Calsakov, the Ming Army did not take the idea of ​​filling in the sale of the castle, because they knew that it was not used.

Luo Junqi's staff and staff are highly students of the Royal Army Military Officer School. They formulated the Ming Army Army, who was born in the gangster.

Advanced, gradually narrowing the surrounding circle tactics. The ultimate goal is to place the entire trading city in the effective range of the Ming Army's superior artillery.

It is very interesting to say. This kind of siege warfare method of long siege city and artillery bombardment, as a similar name of the Wobon 1 -type edge, called "Wo Bang Attack Method".

They are the masterpieces of the great law of law in the early 17th and 18th centuries.

In the middle of the century, it was still regarded as classic by the military colleges of various powers. The Royal Army Officer School of Daming also taught the siege invented by Wo Bang, the method of defending the city and the city to the officers of the Daming Army.

However, in addition to the "Wo Bang attack method", the Ming army also has another attack city weapon -starch explosives.

At the same time as the Ming army began to dig the siege city, a team of carriages were pulling ammunition to the artillery position outside the trading city from 600 miles away, one of which was the Hodiski grenade, filled with

It is the nitric H starch invented by Emperor Zhu -this is also the most powerful explosive in the world at present! The production process is relatively simple. You only need to use concentrated nitric acid, concentrated sulfuric acid, and high -quality starch.

The rough nitric H starch, and then use solid alkali and thick ammonia water to remove the residual acid in the coarse nitric H starch to obtain the nitric H starch that can be used for artillery shells.

Of course, this relatively simple craftsmanship cannot be implemented by the Chinese handicraft industry in five or six years ago. Even at the moment, only Jason's pharmaceutical company and Lan Fangxing's arsenal have energy to produce nitrics H starch, and produce nitrics H H.

The nitric acid, sulfuric acid, starch, starch, soda, and ammonia (of course not synthetic ammonia) such as sulfuric acid, sulfuric acid, starch, starch, starch, and ammonia water. Moreover, most of the engineers who work in Jason and Lan Fangxing in China are mostly hired from Europe.

The road of industrialization is actually that there are no golden fingers and shortcuts to go, and it can only be improved slowly.

Because there are too many foreign engineers working in Jason and Lanfang, the powerful explosives such as nitric H starch can not be used as a secret weapon -this invention has applied for in the world's major industrial countries including Russia,

Patent. So Russian arsenal has also begun to produce nitric H starch for production bombs! However, the Eight Banners in the Russian and traded cities in the Eastern Siberia have no such advanced weapons.

Of course, it is used for the more important Western Front battlefield.

"This is the city's defense map of the trading city?"

On August 8th, Chengde escaped the summer villa, Zhu Jishi looked at the fortress of a snowflake -like fortress in front of him, frowned and asked.

"Emperor, this is not the city's defense map of the buying and selling city, but the standard Wo Bang -style edge map." Liu Jiong, Chief of Staff Liu Jiong, was born in a science class.

The trenches are usually a few feet to ten feet wide, and the trench is the inclined embankment in the trench ... is a large angle slope, which is difficult to climb. When the troops climb the inclined embankment, they will be from the triangle castle.

The cross -fire shooting of prism -shaped and triangular forts such as solid edges and fortresses, almost no dead ends that can be avoided! "

It's really cruel! Emperor Zhu also knows that a carefully built edge castle is difficult to capture!

Zhu Jishi said lightly: "Well, let Luo Junqi don't worry, slowly fight, and make a good preparations for the winter in the trading city. Historically, the Qing Dynasty pseudo -emperor Kangxi hit a city of Yaksa for 10 months and took it for 10 months.

I do n’t know how strong it is better than Jacques, even if it takes 10 months to hit it, it is not shameful. "

Liu Jiongxin said that the emperor is really aware of the soldiers. The most taboo to attack the Castle is irritability. Luo Junqi is not a siege master like Wo Bang. He has not studied the Castle and military engineering before.

Breaking the city, I am afraid to fill it with the blood of the corpse mountains.

"But please rest assured that the design of this Wo Bon 1 -type edge is 1780 years ago. At that time, there was no starch explosives and A explosives."

Liu Jiong said with a smile and said good news: "The staff of the General Staff has found the way to conquer the buying and selling city fortress. In fact, it is also very simple.

At 500 yards of buying and selling the Castle Castle, then the 12 -pound grenades and 24 -pound grenades cannon racks are in the trench. It is the dead end of the cannon guns on the trading city.
