It can only be said that the gap between people and people's strength is too huge. In terms of making guns and cannons, Zhao Shizhen and Zhang Jian, the two brothers, can be called the strongest in the world.

Of course, the fatherly Zhao Gongzi can still point out the direction for his beloved apprentices and nephews, so that they can avoid detours.

The bronze cannons in Europe in this era can be described as dazzling, with all kinds of lengths, shortness, thickness and thickness. However, in view of the fact that in the next three hundred years, there was no essential innovation in the design and casting of bronze cannons. It's perfectly possible to look beyond these oddly named cannons and see what the British have on their sail ships.

Zhao Gongzi launched his natural skill, Human Brain Retrieval, and found that in the two or three hundred years of the British fleet, the naval guns on the capital ships have not changed much. It can be changed back and forth between the five diameters of 6 pounds, 9 pounds, 12 pounds, 24 pounds, and 36 pounds, and the length is basically between 3 meters and 3.1 meters.

In addition to these five long-barreled cannons, the British ships were also equipped with a Caron gun, which was derived from the mortar for melee combat.

Therefore, the task of the eldest nephew was simple and onerous - to build these five caliber long-barreled cannons, as well as thick and short caron cannons, and then finalize them according to the situation of the experiments.

When it was over, Zhao Gongzi thought of the famous Napoleonic cannon again, so he added two more to Zhao Shizhen's cannon list and asked him to play slowly.

Half a year later, Zhao Shizhen wrote a letter to report that all the guns had been trial-produced and passed a long test firing. The conclusion reached made Zhao Hao a little surprised, regardless of the Caron gun, the Napoleon gun, which was only half the length of the long-barreled cannon, was not inferior to the British naval gun in terms of range, effective range and accuracy.

This subverts Zhao Hao's cognition a bit, doesn't it mean that the longer the barrel, the more accurate the shot?

It seems that the Napoleonic cannon is worthy of being the pinnacle of bronze cannons, and its ability is strong and fierce!

Moreover, the rate of fire of Napoleonic guns was much faster than that of British naval guns, and after switching to fixed shells, they could shoot four rounds a minute, excellent!

It is not difficult to understand this, the length of the breech of the front-loading gun is directly proportional to the difficulty of loading, and the relatively short barrel of the Napoleonic gun is of course very friendly to the loader.

Of course, this kind of rapid fire does not last, because the bronze cannon is not heat-resistant, and if it is fired too fast, it will soften, but it is much faster than the long-barreled cannon.

And even more importantly, the same 12-pounder Napoleon gun saves nearly half the copper compared to the British naval gun!

~~

In naval warfare in the Age of Discovery, there was no point in having too large a caliber, and a solid shell with a larger circle could not cause more significant damage than a solid shell with a smaller one. This is also proven in Zhao Shizhen's report, where the power of a 24-pound cannon and a 12-pound cannon is almost the same.

Even the accuracy of the shot is not important, anyway, everyone shoots close to the face, and they can shoot no matter what. From 400 meters away, it will not do any damage to the battleship at all, and if the Galen ships fire at each other, it is not too late to fire again within 200 meters...... The British fired within 100 meters. They made the cannon longer in order to attack targets on the shore more accurately.

So in naval battles, the most important thing is actually the rate of fire and the number of guns. The faster and more numerous I fire, the more damage I will inflict on you. This is the true meaning of naval warfare throughout the Age of Sail.

So, no matter how you look at it, a 12-pound caliber, that is, 117 mm; The large Napoleon gun with a tube length of 14.3 times the caliber, that is, 1.67 meters, is the best choice for getting on the ship.

After some struggle, Zhao Gongzi ordered that the first batch of 300 guns be mass-produced with the Great Napoleon cannon as the main naval gun, which was named the Yongle cannon.

Just considering that when the Marine Corps landed in operation, the 12-pounder gun weighing 557 kg with only the gun body, plus a gun truck weighing several hundred pounds, easily exceeded 1 ton, which was too heavy as a field gun. Zhao Hao also asked Zhao Shizhen to build 100 6-pounder, that is, 93 mm caliber small Napoleonic guns, and named them Xuande cannons, as the secondary guns and field guns of the battleship.

In addition, 100 1-meter-long, 145-mm Caron guns were cast on board as weapons for the fleet's close defense and anti-human damage.

Zhao Hao named this thick and short cannon Hongxi cannon...... It's so apt.

If nothing else, the big black, the fat man and the little black are the three main gun types of the Ritian Fleet.

~~

In the afternoon of the same day, Zhao Gongzi inspected the construction project of the Tamna base non-stop.

Compared with the complex city of Xingang, the construction of the naval base is much simpler, with docks, windshields, barracks, ...... At present, they are all concentrated near the military port.

In order to accommodate a large smuggling fleet, the harbor here is already excessively large. The windshield wall is also much easier to build than the breakwater, so the construction progress here is much faster than that of Xingang City.

Zhao Hao saw that in front of the high windshield wall, the workers were busy setting up a platform to prepare for the establishment of tomorrow's garrison area and the pledge meeting.

"You're all set, aren't you?" He asked something that was not nutritious.

"It's all ready, everything went well in the rehearsal today, and it's ready to go!" Wang Rulong, who served as the commander-in-chief of the expedition, responded in a deep voice.

"Is the Franc Man here?" Zhao Gongzi suddenly asked thoughtlessly.

"Here, the reconnaissance ship reported yesterday that they are still moored in Futianpu, fifty miles south of Pinghu Port, where the wind is high and the waves are fierce, and the conditions of the harbor are very ordinary, and I don't know why they chose to trade there." Wang Rulong nodded, only he and a few people knew that Gongzi set the punishment war against Japan in the autumn, and there was a very important reason, that is, to wait for these red-haired ghosts to come to the door.

"Heto's got a falling out." Zhao Gongzi said without hesitation: "The conditions of the Omura family's Futianpu port are indeed not good, so they are operating through the local church, and they want to obtain another port of the Omura family, Fukaepu, that is, Nagasaki. ”

"No wonder Childe wants the last general to sweep the coast of Kitakyushu." Wang Rulong said suddenly: "You also want me to announce that the main fleet is about to arrive, and when the time comes, 'Sanguang North Kyushu' turned out to scare the Omura family and let them ask for help from the Franco. ”

As for Zhao Gongzi's understanding of Japan, why is it clearer than him, a front-line commander? Wang Rulong didn't bother to think about it at all - because he was a son, was there anything he didn't know in this world?

"How many boats did they have?" Zhao Hao asked again.

"Three of a kind." Wang Rulong immediately presented the sketch drawn by the scout and said: "One is a lucky boat, and the other two are Western ships, please Gongzi Mingjian." ”

Zhao Hao took it over and carefully identified it, the two ships, one large and one small, were hung with complicated Western sails, the larger of which had three layers of guns, and the bow and stern towers were high, which should be a Karak galleon.

The smaller one had only two layers of guns, and the bow tower was not visible, and the stern was very low, which was obviously not as imposing as the larger one.

Zhao Gongzi stared at it without a moment's notice, and his throat trembled a few times, just like a hungry ghost in color seeing a beautiful woman dressed in inches.

"That's what I've been waiting for! Good luck! Zhao Hao shouted excitedly: "You must not let it run!" ”

"That boy, it's best to let the fleet set sail tomorrow." Jin Ke reminded in a deep voice: "The Francophone man has come from far away from Macao, and it can be said that he is alone, and I am afraid that the desire to seek advantage and avoid harm is very heavy, if we know the strength of our fleet, maybe we will pull anchor and return south." ”

"Well, most likely." Zhao Hao nodded approvingly, and said in a deep voice: "Then as long as the wind direction is right, I will go on the expedition tomorrow!" ”

"Yes!" The two of them hurriedly responded in a deep voice.

"I'll go with me, too." Zhao Gongzi added.

"Childe thinks twice...... "King Rulong of Jinke said in unison: "The son of a daughter can't sit down, you must not take risks." ”

"No, this crusade is just a pretext, but it's actually to achieve our multiple goals. I can't rest assured that I'm not going to the front line in person. Zhao Hao said categorically: "Don't persuade anymore, this is an order." ”

"Yes!" The two had no choice but to follow their boots together and respond solemnly.

"Brother Wang, don't worry," Zhao Hao smiled at Wang Rulong, who had been promoted to junior police commissioner, "The commander-in-chief is still you, I promise not to interfere with your battle, I just have to bargain with the little Japanese." ”

"Childe, that's not what the end will mean." Wang Rulong hurriedly waved his hand, in fact, he was really worried about this, of course, this must not be said. "Purely worried about your safety."

"Don't worry, I will be completely obedient to your arrangement." Zhao Hao gave him a reassurance. What are you kidding, is there anyone in this world who is more life-sparing than Zhao Gongzi? "In front of Brother Jin, I authorize you, if I don't listen to your command in wartime, you have the right to let me return, this is all done?"

Wang Rulong said that he didn't dare, but he finally ironed it in his heart, thinking about it, with the wisdom of his son, how could he not know how to pretend to be blind to command?

"It's the last general who is too careful."

~~

Early the next morning, a low trumpet sounded in the barracks under the city.

At the sound of the horn, a group of police officers dressed exactly the same as yesterday, carrying a uniform blue thick cotton backpack, carrying a spear on their right shoulder, and a bamboo water bottle in a blue cloth sleeve on their left shoulder, walked in a neat formation towards the dock under the leadership of the police officer directly under them.

There are also undressed and empty-handed police officers, who are responsible for staying at the base.

A quarter of an hour later, 4,000 officers of the entire garrison area lined up in front of the pier.

There was no sound on the docks, and the four thousand people didn't even cough.

This is not easy, because out of the 4,000 police officers, only 1,500 coast guards have been transferred from the security team and have undergone long-term rigorous training.

The remaining 2,500 people are still sailors of Jiangnan Shipping for a few months. In July, he was transferred to the garrison area and began to receive military training from Director Tong.

Director Tong's magic power is boundless, and in the past two months, he has injected a lot of spirit into them, at least when they stand in line, they look the same as the old police officers.

Seeing this scene, Director Tong, who was holding a pitch-black spirit injection stick, nodded with satisfaction.

He didn't wear a cloak on the outside, revealing a slim dark blue lapel with a short hem and arrow sleeves.

There were three silver bands on the sleeves of his arrows, which, like the three silver stars on his hat, signified his status as a senior police officer.

This time, Director Tong will also go out with the army, urging the new police officers to step up training in addition to performing their tasks, and will inject spirit into them at any time!

With him staring at him, who dares to speak out?
