The first thousand three hundred and fifty-four chapters build the fortress and become addicted to t
Ever since the Tang Empire built the bastions and showed great tactical defense capabilities in overseas territories and border areas, the Datang Empire has maintained great enthusiasm for the bastions, meeting almost all needs.
The construction of the bastion began in the place.
In prosperous inland areas, or areas of great strategic value, the Tang Empire built large and comprehensive fortresses.
For example, the newly built imperial palace in Jinling City is not just a palace. In addition to the magnificent interior buildings, the design of its external palace wall defense system is a typical bastion defense system. Therefore, the imperial palace is actually a very large palace.
A typical bastion only looks majestic on the outside, making people overlook its military defense performance.
Another example is in Jiangyin, where the army built a fort along the river. This fort was also a bastion.
Then there is the Wusong Port Fortress. Wusong Port is not only a naval base, but also a huge military fortress. The center is a large bastion, and there are six small Lingbos around it. There are at least tens of thousands of army soldiers and thousands of soldiers all year round.
Marine Corps garrison.
Coupled with the hundreds of large-caliber artillery on the fort, this place became the number one fortress in the Jiangnan region. The large-caliber artillery on the fort was enough to completely block the waterway into the Huangpu River, and at the same time, it could block the Yangtze River entrance to the sea to a certain extent.
Therefore, we can only partially block the Yangtze River estuary. That is because the Yangtze River estuary is too wide, and the effective range of current artillery, even large-caliber cannons, is actually not much.
Although it is said that raising the elevation angle can obtain a greater range, the maximum range has no meaning in actual combat. It must be an effective range to hit the enemy.
If we talk about the maximum range, even the five-pound cannon that is currently used most and frequently by the land and sea armies of the Tang Empire can reach about three thousand meters.
But this maximum range is meaningless, because only God knows where the cannonball will fly at the maximum range.
Under standard circumstances, the effective range of the Army's use of the five-pound field gun is 450 meters. This distance is basically the limit of the effective range. In actual combat, the Army's use of the five-pound field gun is
Sometimes, we often close to a distance of about 400 meters before firing.
In addition, there are also a large number of equipment, second only to the five-pound artillery, the nine-pound artillery. The maximum range of this artillery can reach 3,500 meters, but the effective range is only about 550 meters. When used in actual combat,
The Army will often close the distance and fire within 500 meters.
As for the navy's ship-borne cannons, although the naval gun barrels used are actually the same as those of the army's field guns, their effective effective range in actual combat is closer.
When the navy is in actual combat, no matter whether it is a nine-pound naval gun or a heavy naval gun of more than fourteen pounds, it will only fire within five hundred meters. In fact, if you want to achieve considerable effective hits and kills,
This distance often still needs to be reduced to less than 300 meters.
In the minds of the naval staff, the Tang Imperial Navy's combat method, especially in decisive battles with enemy fleets, should be to concentrate all the battleships and large cruisers that can be concentrated, and then form one or more battle lines.
Line, the battleships forming the battle line form a line, connected end to end and follow the advance.
Use maneuvers to seize the T-head, and then use broadside fire to destroy the opponent. The firing range of broadside fire is about three hundred meters.
Although the navy's naval guns fire at a relatively short distance in actual combat, this is affected by the bumps of the warships on the sea. If the naval guns are moved to land and have a stable design platform, the hit rate will be higher.
has been improved, thereby increasing the effective range.
However, referring to the Army, its maximum effective range is actually not that high. Based on the standard of about 500 meters, it can only be increased by one or two hundred meters at most, and it is impossible to reach the maximum range.
For this reason, the Navy has thought of many ways to improve the hit rate and effective range of coastal defense artillery. Not only the Navy, but in fact the entire defense industry of the empire is working hard to increase the range of artillery.
And put forward many plans!
Some people want to improve the accuracy of artillery and use more precise cannon-making processes to improve the accuracy of artillery.
Some people are also thinking about improving accuracy by improving aiming methods.
Some people are also thinking of simply using the rifled cannon mentioned by Emperor Sheng!
But it is a pity that whether it is improving the cannon-making technology, developing rifled cannons, or improving aiming methods, etc., these are all influenced by the impression of basic science, and the requirements for materials and processing technology are too high. For now, this problem is temporarily
It's unsolvable.
At least the Royal Institute of Technology said that based on the current industrial and technical capabilities, the performance of the artillery has almost reached its limit, and it is difficult to make large-scale improvements.
Although the military is unwilling to accept this, it can only accept it.
The effective range of the artillery is insufficient, which makes it difficult for coastal defense artillery to block the relatively wide river surface!
The Wusong Port Fort was not enough to completely block the Yangtze River's estuary, so the Tang Empire would build forts one after another in other places on the lower reaches of the Yangtze River, in addition to the large-scale Jiangyin Fort.
Songjiang, Suzhou, Yangzhou, Changzhou and Zhenjiang on both sides of the Yangtze River have built many forts, not to mention Jinling City.
Surrounding Jinling City, there are currently twelve fortresses of various sizes, five of which are river defense forts, and the other seven are city defense forts. On the other side of Jinling City, there is also a 'military camp fortress' in Jiangpu.
, this military camp fortress was actually just a Guards camp at the beginning, stationed on the other side of the Yangtze River from Jinling City to control and defend Jinling City.
Later, defense fortifications were continuously built based on this military camp, although this large-scale fort was simply built. From this, this pure military camp in the past became a standard large-scale military camp with the functions of garrisoning troops, river defense forts, and city defense fortresses.
fortress.
The Tang Empire had no choice but to build numerous forts along the river. The performance of the artillery was not enough, so it had to rely on quantity. When building forts, they were often built on the north and south sides at the same time, using the artillery on both sides to block the Yangtze River at the same time. Otherwise,
If so, with only one side of the fort, it would be difficult to completely block the Yangtze River.
A large number of fortresses and other facilities are built in prosperous areas of the country, especially in the Yangtze River Basin, Pearl River Basin, and Yellow River Canal Basin. These are just in case. More often than not, these fortresses themselves are huge barracks, causing such
As a result, it's because the military now likes to turn military camps into fortresses.
In border areas and overseas territories, the construction and application of fortresses are even more professional.
Basically, the fortresses in overseas territories are not large in scale, but they are more practical. In addition to military purposes, they also have urban functions. At the same time, the construction cost is lower, because many fortresses in overseas territories are directly requisitioned.
The local indigenous people can just give them a bite to eat. Anyway, over the years, when the Tang Empire was building various infrastructure overseas, it never paid wages to the local barbarian indigenous people. Even the food that the barbarian indigenous people eat
The grain was often collected locally. After all, the Tang Empire could not transport grain all the way from the country.
The Tang Empire had only transported food back to the country from overseas territories, and there had never been any precedent for large-scale transportation of food from the country to overseas territories.
Because the Tang Empire ordered a ban on grain exports!
The building materials for building the fortress were also collected locally, and at most they used some cement shipped from China.
Therefore, building forts in overseas territories is actually cheaper than building them domestically. The biggest cost may be bullets!
However, it is much more troublesome to build forts in the border areas. To build these forts in the hinterland of the Central Plains, because there is no time limit and there is no urgent need, the military often mobilizes the militia or the troops themselves to do it. Anyway, it is done day by day.
By the end of the year, I would usually be able to finish my job, and I would basically be self-reliant.
However, in the border areas, due to urgent military needs, it needs to be completed quickly. At the same time, in the border areas, it is actually difficult for the local barbarians to build the city. For example, during the Battle of Hetao, the local Tatars naturally would not go to build the city.
Even if those who built castles in the Tang Empire wanted to use force, they would still run away.
When both materials and manpower require support from the hinterland of the Central Plains, the cost is often relatively high.
When building castles in Heilongjiang, the Navy also made reference to the Army's experience in the Hetao area, as well as the Navy's past operations in overseas territories, so it made two preparations.
On the one hand, they are preparing to follow the methods used in overseas territories and recruit and utilize local barbarians to achieve low-cost or even no-cost construction.
On the other hand, as a precaution, if it is impossible to recruit a large number of barbarian natives, early immigrants or even the army itself will be used to build it.
And now it seems that when Qiu Xiao learned that all the barbarian natives in Nurgan City and the surrounding area of more than ten miles had fled, he knew that it was basically impossible to recruit the natives to build the city.
.
You can only do it yourself!
After more than 4,000 young immigrants disembarked one after another, they began to build the city based on the militia they had formed before. The first thing they started to build was simple city wall facilities.
Although guns and artillery are developing rapidly nowadays, and traditional city walls are basically useless in front of the cannons of the Tang Army, a complete city defense system, especially a new type of defense system such as bastions, is of no use to modern guns and artillery.
The defensive effect is quite good, so the city wall was built immediately.
However, it was not Qiu Xiao's turn to worry about building the city and settling the immigrants. Ying Junzhi of the Immigration and Reclamation Department was naturally responsible for this matter.
