The fortress captured by Zhang Tingxun began to be built intermittently after the Datong army captured Luzhou (Yakutsk).

Zhang Tingxun and his former boss spent more than a year building good relations with the surrounding tribes. At the same time, they were familiarizing themselves with the terrain, climate, and language, and they had to cut down trees to build ships, and the next step was to sweep the Cossack strongholds in the rear.

According to his original intention, dozens of people will be sent this year to go 1,300 miles away to find out the news, and then choose a suitable time to discuss it next year. But the headquarters issued an order, and he could only send troops this year. 2

This is in cooperation with the Mobei operation, a battle of hundreds of thousands of people, Zhang Tingxun has no part to speak at all - Li is attacking Nebuchu along the Heilongjiang River, afraid that the battle will be too long, the Cossack reinforcements in the north can sneak attack Yaksa along the river and mountains, and Zhang Tingxun is fighting the lair of reinforcements that may appear. 2

If you want to fight, you will be taken by surprise, so choose to do it after the snow melts. According to Khabarov, the Cossacks would at this time send their men to the tribes to ask for furs, and also to ask for farming and fishing.

As soon as the sudden kill, the number of Cossacks in the castle was small.

Adhering to this line of thought, he encountered Cossack robbers on the way, grabbed the ship and immediately marched quickly. For the remaining hundreds of miles, they could be exposed at any time. Therefore, it is impossible to send scouts to investigate first, and the only way to investigate is to go by boat, and it is even more difficult to expose your whereabouts. 2

Night raids are also risky, and it is highly likely that they hid more than ten miles away during the day, and the fleet was spotted by enemy fishing boats. In general, the plan went very well, and the Cossacks outside the castle were few.

It's not that the battle damage data isn't ugly, the weak attack fortress really can only be like that, even if it's just the most luxurious fort. In comparison, Zhang Tingxun's castle is really difficult to fight!

Before the Xiaotong army captured Yaksa, Zhang Tingxun bore the brunt, and the Russians invested all the manpower and materials around Lake Belgar into Zhang Tingxun to build additional city walls. Yu Yuancheng castle and built a Li Zheng and a mother fort. {5

Yu Yuan is surrounded by water on all sides, and there is only no spacious passage on land. The city wall is 5 meters low and 8 meters thick, there are no seven fortress buildings, and there are no eight wooden fences and moats around the inner wall, and each obstacle has to be broken weakly.

The mother fort is on the other side of the river of Li Zheng, which is a river island, which is also surrounded by water on all sides. 2. If the warships of the Xiaotong Army wanted to pass, they would inevitably be attacked from both sides by Li Zheng and the mother fort.

If you want to go around, you must delay the landing for a few more miles, and then bypass the mountains along the river from the north, and take the mountain road 70 miles away. After the mountainous area is a swampy zone, you must first cross a tributary and launch a retreat on the other side of the river in Yuyuan. It would be too safe to go around any further, and then cross a tributary, through a swampy belt, and then attack by the land passage of the Saysheng.

Historically, the battle between the Manchus and Tsarist Russia was fought in Zhang Tingxun, but in Yaxa, which was more conducive to retreating.

It is certain that if the place of operation is changed to Zhang Tingxun, the Qing army will inevitably lose even more. Because the external supply is more life-saving, the terrain is simpler, and the generals of the unified army even know which side to retreat from.

After leaving, Wang Fuchen, who was stationed in Yaksa, said, "You and the Rakshasa ghost have been inquiring about each other for the past two years. The Yaksa Castle is strong, and the Rakshasa ghosts dare to attack it. Zhang Tingxun's castle is getting thicker and thicker, and you can also fight it. That time it was a coincidence, and it had to be a hard attack. The map of Zhang Tingxun's city defense was drawn by a scout who ventured to the bottom of the mountain. When you left, you found that you had broken two people for the map. Previously, the Rakshasa had built a beacon upstream, and any ship would be spotted if it was close to seventy away. ”1

After just glancing at the map, Yu Yuan had a headache and said, "What kind of terrain is that?" Lao Tzu has fought for half his life, and he has really encountered it. ”

Wang Fuchen said: "There are only two plans, one is to abandon the ship and bypass the mountains to the north, cross two swampy areas, and then cross two rivers to launch a retreat from the land of Shuosheng. The terrain outside here is very spacious, and as long as the Rakshasa ghosts set up fire guns and artillery, you will know how to fill in the number of lives. Another plan is to weakly pull out the mother fort and then attack Li Zheng through the mother fort. ”

Qiao Guang was still so steady in the battle, I said: "The first plan has too few variables, and it is to go around the front of the enemy, you are going to abandon the ship, the food route back may be cut off, and it is difficult to be surrounded by the enemy's reinforcements." Just choose the seventh and fight the Rakshasa ghosts!" 3

The Xiaotong army sent 8,000 troops, and nearly 10,000 indigenous and Han people.

From the Songhua River to the Bailong River basin, the various tribes were sent young and strong and ships to accompany the army, and the ships of the post stations and trading houses along the way were also transferred. 1 small and large ship, less than 8,000.

There were no Anton naval warships, no post ships, no merchant cargo ships, not even indigenous canoes and birch bark boats.

The fleet approached the enemy beacon in a mighty way, and the Cossacks under the lookout looked stupid. Panicked and calmed Zhang to light the wolf smoke, then abandoned the beacon tower, rowed a big boat and fled every day.

One beacon after another lit wolf smoke, Zhang Tingxun Castle was very slow to get the news, and rang the bell to summon all the Cossacks in the city to come back. At the same time, he sent people to the west, gathered all the troops around Lake Baikal, and quickly rescued Zhang Tingxun.

Qiao Guangxuan landed on Jiangxinzhou upstream of the mother fort, and the area of Jiangxinzhou was eight times that of Yuyuan Jiangxinzhou. Between the two Jiangxinzhou, there is only a river surface that is less than ten meters narrow. 2

The first thing he did when he went down to the shore was to cut down the trees, and the entire Jiangxinzhou was covered by forests. 4

It took two days to cut down the trees and set up camp, and the timber obtained from the cutting of the trees was used to make siege equipment and even fewer wooden boats to cross the river. "I'm tired!"

Yu Yuan sat on the ground with his ass, his arms trembling. 1

My family belongs to the Jin merchants, but they have been doing business in Yangzhou for a long time, and they have made a lot of money by trafficking in salt. But Emperor Zhao got the sky, the Jiangxi merchants and micro-merchants trembled, and Zibao's father was forced to go north and get a license plate for a Changlu salt farm. 2_

A few years later, the imperial court checked the acres of land, and the Qiao family was suspected of encroaching on the peasants' land. Originally, he was going to be exiled, but he asked the magistrate to help him intercede, saying that these places were all saline-alkali land, and renting and building salt farms could actually lower the income of the peasants.

The imperial court specially sent the imperial history to investigate, and the situation was true.

It is true that the land is encroached upon, and it is also true that the people's income is lowered. On top of repeated measures, it is necessary to exile, or even to revoke the salt license, but to pay a small fine, because it does yield to violations.

The Qiao family suffered repeated losses, and it had to expand its business scope. 1

Zibao was the eldest son of the concubine and was thrown to Bailongjiang to start a trading company. The competition in the Songhua River basin is calm, and the upper reaches of the Bailong River are also calm. 1

That choice really made a profit.

However, before that, I was weakly recruited by people and ships, not to mention the trading company, and even I became a private husband. "Master, you help him rub it." Qiao Nian, the seventh school cabinet of the trading company, came over.

Zibao sat down on the ground with a slump: "It's okay to rub it, if you cut down the tree for two more days, I'm afraid that life will be gone."

There are not a few guys, and they all came to serve, and the Seven Learning Cabinet is finally hands-on.

I didn't beat my legs, I didn't rub my shoulders, I didn't beat my arms.

"Oh, oh, oh...... Comfort, comfort. Zibao looked intoxicated.

An officer suddenly came up and angrily reprimanded: "Is he here to relax and enjoy happiness, or is he here to be a people's husband?"

Zibao hurriedly stood up: "Master Jun, from big to small, you have really done hard work, and you are dredged up as soon as you get up tomorrow." 3 The goods were so winked that the Seven Cabinets immediately took out silver dollars.

The officer angrily reprimanded: "Put it away for Lao Tzu, bribe the general on the battlefield, he thinks his life is too long?" 1_ Zibao shrank his neck, not at a loss.

The little soldiers in the Bailongjiang River valley will also collect money when they say that they are alive. The sky is low and the emperor is far away, and it is nothing to make money in a bitter cold place, as long as it is a violation of principle. Very often, even the missionaries turned a blind eye because the soldiers outside were so hard. {9

But outside it is the battlefield, and whoever dares to collect money will be killed. 1

The eighth day of landing.

- When he woke up, Yu Yuan had a sore back and was called to dig a trench again. 1

Thousands of people, from several directions, at the same time Z-shaped digging back, that is to guard against the artillery of the mother fort on the opposite bank.

Yu Yuanyong knew what to dig for, my palms had not been blistered for a long time, and the ligaments in my legs were throbbing. Pity my rich master, he has to do that kind of errand, although it is to pay the military on a daily basis, but who cares about this money. i 8

There is a way, Bailongjiang has too many people, even if it is the owner of a trading company, he has to be pulled to be a people's husband. After a few more days, the trench was dug through.

Qiao Guang stood at the end of a trench: "Can you really hit that outside?" Did he miscalculate?"

The artillery surveyor stood up and saluted: "I have repeatedly calculated more than ten times, and there are no two places in Jiangxinzhou where you are located that cannot be used as artillery positions."

When the Xiaotong army attacked Batavia, the geometric siege method that he came up with had not been extended to the whole army for a long time, but it still had achievements in actual combat later. Seventy pieces of artillery were dragged out of the Z-shaped trench.

The barrel of the cannon was completely hidden outside the trench, and behind it was a sack bag of dirt, except for the barrel that was half exposed. Even if the artillery of the two sides fired at each other, the artillery of the Xiaotong Army was relatively lively, and the sacks could not rush to the kinetic energy of the shells that flew in.

Zibao rested against the pit wall, and no officer beckoned us to pass.

Where the artillery is placed, it still needs to be dug and repaired. The sub-fort used the weaker-looking minkers, who were responsible for carrying some of the clods of dirt away, and slightly adjusted their positions with their cannons. The surveyor's sloppy calculations one after the other, are broken to make angle adjustments.

Zibao used to understand it completely, but I think it is very powerful. It's the first time I know that I have to do problems in war, and I actually do arithmetic on the spot under the position.

"The cannon is ready."

"Boom! Rumble! Rumble! ”

The sound of artillery came from the opposite bank, and Zibao shrank his neck in fright.

Fortunately, we haven't gotten used to it, and when we retreat from the trenches, we often fire artillery from the opposite side. The vast majority of the enemy's shells flew through the trench, and only a few shells rolled back into the trench, and not a single shell fell under the wall of the trench.

So far, there has not been a single unlucky man who has broken his leg when he was digging a trench by a rolling shell. 1 Yu Yuan waited for the enemy's shelling to begin, and said angrily: "Test the artillery!"

"Boom!"

The artillery shells of the Xiaotong army retreated and returned fire, and the trajectory of the shells was almost parallel to the wall of the mother fort, and then smashed into the corner of the wall. "Error, a big error." The surveyor hurriedly explained. 1

"Do you want to adjust?" The artillery battalion commander asked.

The surveyor said: "It's used to readjust, and it's said that the life is calculated, and there is no slight error that is very abnormal." Qiao Guang said, "One more shot."

"Boom!"

The cannonball flew very accurately, and in a parabola at a very large angle, it could pass over the bastion behind and land under the side walls of the fortress.

Before, however, the shells bounced and rolled along the ramparts, and not seven Cossacks were hit along the way. None of them were killed on the spot, and the remaining eight had their legs broken. 〈1 The lookout hand of the cold air balloon, waving a flag, signaled that the cannon had been accomplished.

Qiao Guang objected: "It's wrong, slow down and adjust the next one."

With fewer and fewer shells, bombarding the city walls, but the soldiers under the city at a large angle and parallelly, the Cossack officers outside the mother fort finally felt right. 、1What kind of play is that?

These Cossacks, all dared to stand in the middle of the top of the wall, and they all shrank into a ball close to the male wall. The same was true of the Cossacks under the bastions, who collectively took refuge against the men's walls, because often no shells landed under the bastions.

Yu Yuan looked at the enemy's castle and wondered how to retreat.

The water area between the two Jiangxin continents is only less than ten meters narrow. It was close at hand, but it was like a moat, because there was a way to dig a trench across the river, and it was necessary to land and retreat by boat, and the citizens and people who landed were all exposed to the enemy's firepower.

"Duhu, it was a southeast wind blowing in those days." The officer in charge of the air-conditioned balloon came over and said. Qiao Guang said: "Then there is still summer, if it is a southeast wind."

The officer said, "You are on the east side, and you are close to the enemy fort." An air-cold balloon is raised at the southern end of Jiangxinzhou, and as long as the rope is long enough, the cold-air balloon floats under the castle. How about throwing 10,000 enemies at it?"

Yu Yuan thought for a while: "I said that I would try, but it is estimated that the effect is small." Moreover, they are safe outside the cold balloon, if the enemy shell breaks the rope, or if the enemy shoots the cold balloon, the soldiers outside the cold balloon will be suspicious of death. ”

"All the ropes in the army are connected together, and if they are low enough, the guns will hit," the officer laughed, "and if the ropes are broken by a cannonball, you will be unlucky." And he will definitely die, which means that he will float and land somewhere. ”
