Although Marin is a bit shameless in his own way, the single-headed shells are really powerful. After testing, the single-headed shell made of cement is fired using a three-pound cannon, with an effective range of 500 meters. At a distance of 200 meters, 20 wooden doors can be penetrated.
These wooden doors are made of imitating the bearing capacity of the human body. Punching through a wooden door is equivalent to punching through a person. Of course, the resistance to wearing plate armor is much greater. In other words, a three-pound muzzle-caliber cement single-headed shell can penetrate 20 soldiers without plate armor at a time. Moreover, the trajectory is very straight, and it looks like a bamboo stick passing through barbecue, very standard and straight...
This is very terrifying. If 100 cannons are lined up in a row and they all use this abnormal shell, and hundreds of cannons will be fired together, and 2,000 people will be taken away at one time...
According to the ancient principle that the army collapsed with 10% casualties, a round of artillery can destroy an army of 20,000 people at one time!
This is just one round of launches. If you fire a few more rounds, you can directly kill 20,000 troops on the opposite side... Well, at least the enemy troops facing the artillery are gone...
Seeing that the cement shells were so powerful, Marin once again casted iron shells by sand casting. After testing, the effect was even more amazing!
The cement shells are not strong after all. Every time they penetrate the wooden door, the cement shells themselves will have some bumps and losses. The iron ball shells are powerful, and there is no loss when they penetrate the wooden door. In addition, the iron bullet has greater kinetic energy, and it actually penetrates 40 wooden doors, which is so cruel!
"Damn, this is almost as good as the little Napoleon!" Marin was shocked.
The little Napoleon cannon is the M1841 6-pound cannon. This cannon can penetrate half a company, which is about 50 people. The 12-pound Napoleon cannon can penetrate the entire company!
But this single-headed shell was fired by a three-pound cannon. The charge amount is incomparable to the 6-pound cannon, and it is only half of the opponent. It can actually achieve almost the same effect. It is amazing!
But when you think about it carefully, you feel it is very reasonable! Why? The little Napoleon cannon uses an iron ball, and its penetration power is incomparable to the pointed bullets of a single-headed shell. What's more, the pointed bullets can rotate, which is similar to the drill bit effect, and has stronger penetration power.
Therefore, the single-headed shell fired by the three-pound cannon fired a penetrating force of nearly 6-pound cannon iron ball shells!
"This is a damn! This is a damn..." Marin walked around excitedly. Suddenly, his eyes were fierce and he looked at everyone present...
Kohler suddenly felt nervous, he knew-Marlin wanted to silence...
Of course, Marin's so-called silence is not a murder to silence people, but sending those who know the secret to the Americas and monitoring them at the same time.
Of course, it's not time yet...
...
Then, Malin led the entire team to test the bombardment of warships with iron shells. As a result, the ordinary level 250 armed merchant ship was directly penetrated by the side. Only the serious Hoffman-class warship had withstood the test and was not penetrated. However, it was also beaten to pieces. As long as the same part was hit twice more, it would definitely penetrate!
"Damn, this is too sharp... so sharp... Monkey Sailai..." Marin murmured to himself.
In this era, the side side of warships in other countries did not thicken and the keels did not increase in density, which looked similar to the level 250 armed merchant ships. It can be said that this single-headed shell could break the side side of warships in any other country in this era.
Even if the opponent's warship is thicker, Marin can increase the caliber. You must know that this is just a three-pound cannon bombardment of a single-headed shell. If it is replaced with a 6-pound cannon, even the warships that have been strengthened over the sidewalks of the Beihai Kingdom will not be able to bear it.
As for the city gate? Malin led the team to conduct a test. The wooden city gate could not withstand the iron single-headed shells at all. Even if the city gate was full of things, it would be fine. At worst, a few more shots could be fired. Even if a 12-pound cannon was used, the iron single-headed shells could be made bigger and the city wall could be blasted open!
...
"No, my blood pressure is a little high!" Marin was a little scared. In this era, this is simply a nuclear weapon-level thing. So Marin's eyes were fierce again...
"It must be kept confidential! Kohler, look..."
Kohler nodded and said directly:
"I understand that all immigrate to America and send spies to monitor 24 hours a day! If anyone dares to disclose it casually, send it to God immediately..."
"Well, give them a chance, and their wives can accompany them. The children... let them choose to take them away or not..." Marin thought for a while.
Then Kohler waved his hand and a group of guards came up to tightly isolate all the craftsmen participating in the test and shell manufacturing.
These craftsmen were filled with fear on their faces and began to beg for mercy loudly. They were not fools who could become senior craftsmen. Faced with such terrifying power, it was normal for Marin to "silence"...
But Marin is not the murderous devil after all. Before leaving, Marin still shouted to the craftsmen who begged for mercy:
"Shut up! I didn't say I wanted to kill you! But you will live in North American colonies in the future and cannot come back. In addition, keep your mouth in check and don't talk to others, even if your family is not good! Once someone talks outside, he will be executed with his family! Even if you escape to another country, even if you escape into the French palace, I can still take people to chase and kill all those insiders!" At the end of the day, Marin's voice had no concealed murderous intent at all.
Not to mention these craftsmen, even the guards who arrested craftsmen around were beginning to be scared. Many people looked down at the ground, afraid of seeing something they shouldn't have seen...
Hearing that there was no need to die, the craftsmen present breathed a sigh of relief. Most of them chose not to take their children if they asked them to choose whether to take their children. Because they also knew that they would definitely live in surveillance in their lives. Moreover, they would definitely not live in lively places, and they would generally live in remote places. If they brought their children with them, it would be considered a ruined child. Therefore, most of them only chose to take their wives away, and the children and the elderly were left behind. There was only one young craftsman, because the child was just born and there were no elderly people at home, so they chose to take their children with them.
...
After sending away more than a dozen craftsmen who participated in the manufacturing and testing, Kohler said worriedly:
"Young master, don't we use this kind of shell in the future? What a pity..." Kohler was very shocked by the power of the one-headed shell. At the same time, he was also afraid that the secret would be leaked like Marin.
The technical content of single-headed shells is not high and can easily be imitated. If a major artillery power like France obtains technology, it will be a life-threatening death. At that time, the surrounding countries will not be France's opponents. And the Beihai Kingdom, which also masters the technology of single-headed shells, will definitely become a thorn in France's side. At that time, both sides will definitely fight hard, and only one side can survive.
Marin sighed and said:
"Let's do it first, I'll think about how to arrange it next..."
Marin was also very troubled. The power of the single-headed shell was too much beyond expectations, which made him a little scared. This level had reached the power of the early Civil War in the 19th century, and was more than 400 years ahead. Marin did not dare to take it out casually, but he was unwilling to let it go if he put it aside...
After thinking for a day and a night, Marin made up his mind:
"Korle, you should choose 700 most loyal children from the military academy. It is best to be stupid and a little strict. But you can't be too stupid. At least you have to know how to use artillery... Well, these children are called Guard Artillery, 'Loyal Guard Artillery'..."
Obviously, Marin plans to learn how to deal with single-headed bombs before, and use the most loyal and fanatical teenager to control single-headed shells that need to be highly confidential.
"Okay, I'll send someone to the military academy to choose. First, exercise your normal artillery ability, and then transfer it to control the new shells when you become proficient!" Kohler understood in seconds. After following Marin for so long, he was familiar with Marin's routine.
An infantry artillery squad usually has 7 people, usually composed of a gunman, aiming hand, firing hand, loader and ammunition hand. 700 people control exactly 100 artillery pieces. There are 100 artillery pieces that use single-headed shells, and Marin is confident of defeating any army in this era.
The only thing I worry about is that if the opponent cannot be eliminated at once and the opponent finds the secret of the one-headed shell, it will be very dangerous. Therefore, Malin knew that the one-headed shell was very powerful, but he must hide it first. When his strength is strong enough, he can push the French and German princes at one time before he can use it.
A flat push is not a defeat. If you only need to defeat, you can defeat your opponent by using a single-headed shell. However, due to the number of people and fame, it cannot completely solve the opponent in one go, and the opponent still has a chance to turn the tables.
To push to the side, Marin must have at least 200,000 troops and very sufficient military equipment to make the French and German princes unable to turn over again.
Therefore, Marin planned to hide the one-headed shells first. After he solved the Grand Duchy of Moscow and cleaned up England, he could free up his hands to deal with France and hostile princes before he could use them.
Before that, the most important thing for Marin was to form an absolutely reliable artillery unit to ensure that the secrets were not easily leaked.
Therefore, these 700 guard artillery will be Marin's biggest trump card in the future and the biggest back-end to Europe.
