Sun Zhaojian took Melgen Camp and the song camp was dispatched!

After the fourth year of Zhaoxiang (762), at the suggestion of Jia Dan, the Minister of Personnel, the name of the Sacred Ye Jun was standardized. Specifically:

The shattered Ye Jun allowed privately and the people to continue to call him;

It is called the Qin army uniformly to the outside world;

As for Sun Xiurong's five major guard camps, Bogda camps, and Bogda camps, they all came from the honorable titles he once had - Bogda Khan and Bogda Khan, and the Ying Qin Dynasty called the "Guard Wei" for the guards, Sun Xiurong used his adopted son, Sun Xiaoke, the commander of Bogda Camp, as Duke Duan Guo, and the general of Huaihua and the commander of the guards, and was in charge of the two battalions as the commander of the Bogda Camp.

The Ying Qin Dynasty called the army commander of the capital except the Weiwei. Sun Xiurong also appointed Yu Que as the lieutenant as Duke Li and General Huaihua, in charge of the third battalion of Aslan Camp, Melgen Camp, and the romance camp.

Of course, for Sun Xiurong, he was not very clear about the distinction between "palace city", "imperial city" and "capital city". In fact, the five major camps were used together.

But no matter what, both the Guard and Lieutenant were ranked among the nine ministers, and in fact they were already in a high position, far surpassing the ordinary Duwei.

Therefore, since the establishment of the personal guard camp, the commanders in other camps have basically been changed every three years, but the five major personal guard camps have never been replaced. This shows Sun Xiurong’s trust in these five commanders, and also implies his special thoughts.

Yes, the Great Qin Kingdom did not have a huge royal city. All the castles except for the scale of the Datang County Town were built (5 to 10 miles in circumference). However, as long as these five camps were there, the Great Qin was there and the King of the Great Qin was there, which was somewhat similar to the later Da Liao.

Although the Great Liao had five capitals, the emperor (Khan) rarely stayed in a certain city, but kept swimming in the vast territory. The most elite 20,000 palace tent army (equivalent to the Guard Army) and 80,000 vites (equivalent to the Lieutenant Army) were also moving with them. Where there were palace tent army, there must be emperors.

Of course, this is also because Sun Xiurong has not obtained his ideal territory at the moment. If he really gets it, he will still build a huge city for himself and build a huge city worthy of his strength for the country.

Yu Que is Sun Xiurong's cousin and the prime minister of the Lifan Academy. It is reasonable to have him serve as a lieutenant. However, since Sun Zhaojian arrived, Yu Que gave up his power, not only gave up all the seals, tokens and banners belonging to the "Lieutenant", but he also became Sun Zhaojian's "affiliate".

Yu Que did this not only because Sun Zhaojian was the second son of Prince Pingyang, Sun Xiurong, but also the former lord of the grassland and the true descendant of the Blue Turkic nobles. It is also because the current five major guard camps are no longer the previous guard camps, but the new changes in guard camps.

Such changes were not easily controlled by a person known for his bravery, who was born in the wilderness. Sun Zhaojian, who grew up with Sun Xiurong's heart-wrenching teachings since childhood, did not have this problem.

As mentioned earlier, the composition of a camp of 5,500 people is:

There are two thousand cavalry, including five hundred heavy cavalry and one thousand five hundred light cavalry, of which heavy cavalry can be used as light cavalry under normal circumstances;

Two thousand infantry and horse infantry can also be used as cavalry in emergency situations, including five hundred heavy infantry, one thousand strong crossbowmen, and five hundred light infantry/packet troops/engineers;

Five hundred shamans, five hundred cavalry, five hundred artillery, and five hundred artillery are the military forces directly under the command of the Duwei. Among them, two hundred Yuhou Army serve as the Duwei's investigation, staff, flags and drums, law enforcement, merit test, performance test, pension, and investigation.

At present, the generals in charge of two thousand cavalry or two thousand infantry are also the deputy lieutenant, while the Du Yuhou actually controls the direct-level troops of the Du Sui. The military strength that truly belongs to the Du Sui is to put aside the 300 cavalry outside the two hundred Yu Housing Army.

At the moment, since it is the most elite unit of the Great Qin Kingdom, there have been changes again with the unchanged number of people:

Five hundred cavalry of 1,500 light cavalry can also be transformed into heavy cavalry as needed;

Five hundred of the 1,000 crossbowmen can also be transferred to the artillery battalion or light infantry battalion as needed. When marching, they carry a large number of side vans, artillery, crossbows, etc. with the light infantry battalion, and cannons can be easily converted into the war according to their needs.

This is all secondarily. The most critical change in the personal guard camp is still the artillery.

The crossbow cannons in the Bird Cannon Camp have not changed, and they are still modified from previous car crossbows. However, with 500 reinforcements at any time, the number of crossbows has naturally increased greatly.

In the past, the Qin army was configured with ten people, one cannon or one crossbow. In that case, they would generally carry forty cannons and ten crossbow cannons. However, when 500 people in the powerful crossbow camp could reinforce at any time, in dealing with the huge number of enemies, the artillery may increase to sixty, and the crossbow cannons may also increase to thirty.

That's not all. At this time, since Sun Xiurong "boldly" launched a large-scale war against the Xhosa Khanate at the same time, he must have something to rely on, and the main reliance is on the artillery.

Yes, this time, the Qin army finally equipped the siege cannons.

Considering the weak long-range firepower of the enemy and the convenience of carrying, Sun Xiurong still chose a short-barrel artillery.

In later generations, during World War II, a mountain cannon with a diameter of only 70 mm, a length of only 700 mm, and a weight of only 200 kilograms could attack targets far away at an initial speed of about 200 meters per second, but that could only be achieved under the situation of new gunpowder.

At present, although the formula, refining and maintenance of black gunpowder have reached the level of later Qing dynasties, the power is insufficient in the end, and the kinetic energy it brings is about one-fifth of that of new gunpowder. The longer the gun body, the faster the initial speed of the shells.

Therefore, to achieve the effect of the small mountain cannon in later generations, the body tube ratio of the cannon driven by black gunpowder should not be smaller. Compared with the mountain cannon, its smallest length should be more than three meters and five meters. However, considering the steel at this time, the gun wall is generally thick, and a cannon more than one meter long is indeed worthy of the word "cannon". With the thick gun wall, it is impossible without a few thousand kilograms.

The maximum load of the four-wheeled side van in the Qin Dynasty is two thousand kilograms and the effective load is one thousand kilograms, because in such a situation, it can be easily pulled up by two pack horses, and the strain on the side van will be minimal and can be used for a long time.

So one thousand kilograms became the upper limit of the weight of the Ministry of Industry of the Great Qin State for the development of new artillery. Of course, according to the usual practice of the Great Qin State, the gun stands and ammunition are installed separately. In fact, a complete set of artillery also has two thousand kilograms, but if it is installed separately, it will be too late to assemble it when you arrive in the ground.

Finally, Sun Xiurong gave up the body tube ratio and chose the caliber. The newly designed gun had a caliber of 30 cm wide, but was only two meters long. If it was to reach the range of the mountain cannon in later generations, it would have to be three meters and five meters. Therefore, such a cannon was only 60% powerful, but it was also 1,800 meters, which was about three and a half miles away.

In the case where the enemy does not have such long-range weapons at all (the catapult is far from reaching and the accuracy is far inferior), this is enough. If such a weapon is used on a ship and bombarded within nearly one hundred meters, it will be the enemy's nightmare.

It is quite calm when used on land, and is more than three miles away.

The final parameters of the Qin army's thousand-pound cannon are:

The cannon body is 210 cm long;

The inner diameter of the gun barrel is 30 cm and the outer diameter is 33 cm, which means that the thickness of the gun wall is three cm;

In this way, the cannon body alone is only 490 kilograms!

Including the 490-pound gun mount used to absorb the rear slump of the cannon, and a 500-pound ammunition that can be stabilized, a set of Daqin version of the thousand-pound cannon can be easily pulled away by two side vans, and there is also an additional portion of gunpowder.

Such a cannon is thick and thick, and can carry a solid iron bullet with a diameter of 30 cm and a weight of 200 kilograms!

To push such an iron bomb, at least fifty kilograms of gunpowder is required!

Therefore, loading such ammunition is also a technical job, but there is no way to do this. When in Kangcheng, Sun Xiurong tried it. The shells with a diameter of less than 30 cm were popular in the Persian region, the Khanate of the Xhosa Khanate, and the Roman Empire were mostly very thick, unless you bombard them at all costs. Such things were obviously not what he wanted to do.

The 30 cm and 200 kilogram shells weighing 30 cm have been used to smelter iron by the world's most advanced steel-drawing method and learned to add manganese materials. The thickness of the three cm gun wall is the least, otherwise the blow-off will be certain.

Two hundred kilograms, four artillery soldiers were picked up with one net bag. Fortunately, he organized a large number of artillery soldiers from the beginning. Otherwise, if he was careful, he would still be in a difficult position when he was in the end.

Such artillery is naturally not as powerful as the power of those artillery in the late Ming and early Qing dynasties in later generations, whether it was the Ming and Qing dynasties (when they captured Yangzhou City and Tongguan, they used heavy artillery of tens of thousands of pounds that required more than a dozen cows to pull, and the artillery on Western battleships was often several thousand pounds). However, as long as you find the right place (the thinnest part of the city wall) and get close to bombardment, it will take only half a day to achieve the effect.

If this kind of artillery is used on a ship, as long as it is hit, one will be enough to destroy a large ship!

If this kind of "conscienceless" artillery fireshot cannon can spray a pack of 600 pieces of lead, each of which is about one or two pieces, at an astonishing initial speed. After spraying, it will immediately form a shotgun storm with a barrage of about fifty meters in front of it, such a shotgun storm that is squirting up, down, left and right forty-five degrees.

This kind of storm cannot be stopped in today's world.

"Not at all!"

After entering the oasis near Jetzanburg, Sun Zhao gradually photographed a heavy black pound loaded on a side van, which was nicknamed by the Qin army as the "Gonggong Cannon" (even Buzhou Mountain can be touched, so it is naturally powerful). The sigh in his heart couldn't help but feel aroused.

However, if you think about it, the consumption of gunpowder and shells by such artillery can be too amazing. Even the wealthy Qin State cannot let it kill for many days. In that case, the Qin State will be declared bankrupt within a few years.

But no matter what, with the blessing of Gonggong Cannon, all the Qin army was full of confidence in taking down Mulu City.

This is the biggest secret of the personal guard camp.

Of course, such a powerful weapon is not equipped with ordinary camp.
