Gushihan's head was buzzing and his ears couldn't hear.
He was already over fifty years old and had some hearing loss. Now, he couldn't hear clearly.
Because they, the leaders, were surrounded by guards. And the distance was very far, so it was not affected. Unlike the cavalry on the right wing, many of them were shocked to the point where blood flowed from their ears.
He Duo and Qin's slender eyes rolled. I don't think it's going to work like this. It's obvious that the first shot was a test shot. The enemy must want to attack these Khans and Taijis. Don’t the Han people always talk about capturing the thief and capturing the king?
It would be bad if we continue to fire here. Looking at the power of this, if we really hit it, we might kill King Khan and Taiji in one fell swoop.
He Duo and Qin no longer hesitated, immediately grabbed the reins of Hala Huji's horse and left. The other guards watched as the young master led the Khan's horse to the back of the hillside. He followed immediately.
The others were not fools either. When they saw that the Dzungars were hiding behind the mountains, they also ran back.
Yang Fan put down the telescope and said with some regret: "The first shot missed. They were quick to see the opportunity. They ran to the back of the mountain. Now they have no chance to fight."
Zhang Fengyi asked in confusion: "Brother Yang, why don't you fire another shot, or fire towards the back of the mountain."
Yang Fan pointed downward and said: "You see, loading a shell is very slow. There is too little time. The next shot cannot be fired in less than five minutes. So if they want to run, there is absolutely nothing they can do. That hillside can be reached in the blink of an eye. Gone behind."
Zhang Fengyi quickly used her small hands to hold the front porthole and looked down.
Sure enough, the sailors below were hesitating and struggling to reset the cannon.
Others held mops and buckets to cool down the cannon chamber and extinguish the sparks in the cannon chamber. Otherwise, if the next medicine package is filled in, it will explode immediately.
And that kind of powerful cannonball is also very heavy. It weighs a full 200 kilograms, and one person cannot lift it. A corps of loaders also relied on pulleys for lifting.
Even in modern times, the shells of the 203mm main gun still need to use a loader.
Whether it is the B4 howitzer of World War II, also known as Stalin's Hammer. It is still the 2C7 203mm self-propelled cannon still used on the Wudong battlefield. They all come with their own semi-automatic loaders.
There is no loader on this boat, so 40kg light bullets are usually used. Use after reducing propellant packs.
The main purpose is to facilitate loading.
In this era, 40 kilograms of artillery shells were enough to bombard the city wall.
Even during World War II, heavy cruisers were equipped with 203mm main guns.
Cruisers are rather strange, and they are not classified by tonnage, armor, or power. It is divided according to the caliber of the main gun equipped.
Those equipped with 155mm and 152mm calibers, that is, six-inch main guns, are all called light cruisers. Those equipped with a 203mm caliber, which is an eight-inch main gun, are all called heavy cruisers.
The larger the caliber is, the battlecruiser, and the higher is the battleship.
Although this ship is only 200 tons, it is equipped with a 203mm main gun. So it's a heavy artillery. There is nothing wrong with calling it a shallow water heavy gunboat. Totally well deserved.
Only then did Zhang Fengyi see clearly that there was a hatch on the deck in front of the main gun, which was open at this time. There are also brackets and pulleys there, and chains are used to lift 100 kilograms of heavy artillery shells from below.
Resetting the artillery is a laborious task. The cannon weighs five tons, or 10,000 kilograms! Even Zhang Wudian was stunned by this weight.
It took a dozen people a lot of effort to use the pulley block to reset the artillery. Then the gunner needs to level the barrel again. If it doesn't lie flat, it can't be loaded. After loading, re-adjust the artillery pitch angle and direction for aiming.
The ammunition hand loaded ten-pound propellant packets wrapped in white silk and added with sugar into the gun barrel one by one. Then use the push rod to compact.
At this time, there were four or five loaders, hanging the shells on pulleys, and loading them bit by bit from the muzzle.
Zhang Fengyi stamped her feet anxiously.
"Brother Yang, this is too troublesome."
"Are you bothering me? This is fast. However, it should be improved. Add a slope behind the barrel. When you recoil, go up the slope. Then it will automatically slide back by gravity and reset automatically. This can reduce the labor of the artillery, but This will increase the dead weight. This kind of inland river boat has small space and light load, so its own weight must be strictly controlled," Yang Fan said.
There are many ways to deal with artillery reset. If it is a coastal defense gun, you can completely use the slope method, but on a ship, this will waste a huge amount of weight.
"Brother Yang, look, they are ready. Once they are ready, quickly fire a cannon at the back of the mountain to kill those Taijis."
Yang Fan smiled bitterly, you think so. He is not a fool, he ran away long ago.
"Our artillery is a cannon, not a howitzer. It can only shoot directly and cannot hit the enemy behind the mountain." Yang Fan explained patiently.
"Brother Yang, what is a howitzer and what is a cannon?" Zhang Fengyi asked like a curious child.
Yang Fanxin said that it was difficult to distinguish them. The short and thick ones were howitzers. The thin and long one is the cannon. But he is not stupid enough to make such a dirty joke with a girl. It is estimated that when Zhang Fengyi reacts, she will immediately raise her pink fists and give this scumbag a pair of panda eyes.
"Look at the mountains in the distance. If you connect the high points, it will be a line, right." Yang Fan pointed at the distant mountains and said. "In military topography, this kind of line is called a ridge line, or ridge line for short. A ridge line is a line formed by connecting the highest points of a mountain range. It is the line at the top of the ridge. It is usually also the watershed line or the watershed line. Watershed. A watershed is used to distinguish the drainage basins of different rivers.”
Zhang Fengyi's eyes were full of little stars. Ever since she met Yang Fan, it seemed that a door to military knowledge had opened. Yang Fan was full of knowledge that she had never heard of before.
"Cannons are used for direct fire, and are generally used on naval ships. Because the sea has no terrain undulations. The cannon's barrel is long and slender, so the trajectory is straight and it can hit far. The howitzer's barrel is relatively short and thick. Shooting The angle is high and the trajectory is parabolic. Although the range is short, it can hit the enemy behind the mountain. If the trajectory is higher, it is a mortar. Howitzers and mortars adopt high trajectories and can cross the ridge line to hit the enemy behind. Go over the wall and attack the enemy inside the city. You can attack the enemy even if they are hiding in the trench. I call the mortar a mortar."
Zhang Fengyi quickly took out a small book from her arms, took out a small writing brush, and stuck out her pink tongue. Lick it with your tongue and record it at high speed.
"I understand, Brother Yang, those Taijis have gone behind the hillside. That is to say, hiding behind the ridge, you must use mortars, that is, the mortars or howitzers you mentioned to attack them. . There is only one naval gun on this ship. It is a cannon and there is nothing we can do about it, right?" Zhang Fengyi raised her head and asked.
Yang Fan didn't expect that this girl had a strong learning ability. She had such a smart mind and could understand it just once she said it. It seems that he does have some talent for military affairs.
"Yes, there is a reverse slope behind the ridge. Cannons can't hit it. If the enemy is building fortifications on the reverse slope, it will be very difficult. The artillery can't hit it. If the infantry rushes over, it will be attacked from behind by the enemy relying on the reverse slope fortifications. Strike.”
