Gushihan's head was buzzing and his ears could no longer hear.
He was already over fifty years old and had some hearing loss. Now, he couldn't hear clearly.
Because these leaders were surrounded among the guards and were far away from each other, they were not affected. Unlike the cavalry on the right wing, many of them were shocked to the point of bleeding from their ears.
He Duo and Qin's slender eyes rolled. They felt that this was not possible. It was obvious that the first shot was a test shot. The enemy must want to hit these Khans and Taijis. Didn't the Han people always talk about catching thieves?
Capture 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 all at once.
He Duo and Qin no longer hesitated, and immediately grabbed the reins of Halahu's horse and left. The other guards watched the young master holding the reins of Dahan's horse as he headed toward the back of the hillside, and immediately followed.
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 and ran to the back of the mountain. Now they have no chance to attack."
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, it is very slow to load a shell. There is no 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 will reach the mountain 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 brought mops and buckets to cool down the gun barrel and extinguish the sparks in the gun barrel. Otherwise, they would fill in the next explosive package and explode directly.
And that kind of powerful artillery shell is also very heavy. It weighs a full 200 kilograms, which cannot be lifted by one person. A team of loaders have to rely on pulleys to lift it.
Even for modern 203mm main gun shells, a loader is required.
Whether it is the B4 howitzer of World War II, also known as Stalin's Hammer, or the 2C7 203mm self-propelled cannon still used on the Wudong battlefield, they all have their own semi-automatic loaders.
There is no loader on this ship, so 40kg light ammunition is usually used. It is used after reducing the propellant pack.
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, the only heavy cruisers equipped with 203mm main guns were heavy cruisers.
Cruisers are rather strange. They are not divided by tonnage, armor, or power. They are divided by the caliber of the main guns they are equipped with.
Those equipped with 155mm and 152mm caliber, that is, six-inch main guns, are all called light cruisers. Those equipped with 203mm caliber, that is, eight-inch main guns, are all called heavy cruisers.
The larger the caliber is, the battlecruiser is, and the higher caliber is the battleship.
Although this ship is only 200 tons, it is equipped with a 203mm main gun. So it is a heavy gun. There is nothing wrong with being called a shallow water heavy gun ship. It fully deserves its name.
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 were also brackets and pulleys there, and iron chains were used to lift 100 kilograms of heavy artillery shells from below.
Resetting the artillery is a laborious task. The cannon weighs five tons, 10,000 kilograms! Even Zhang Wudian would be staggered by this weight.
It took a dozen people a lot of effort to use the pulley group to reset the gun. Then the gunner needed to level the gun barrel. If it was not leveled, it would be impossible to load the gun. After loading, the gun could be re-adjusted in pitch angle and direction for aiming.
The ammunition hand loaded the propellant packets weighing ten kilograms each, wrapped in white silk and added with sugar, into the gun barrel one by one. Then they were compacted with a push rod.
At this time, four or five loaders used pulleys to hang the shells, and loaded them bit by bit from the muzzle.
Seeing this, Zhang Fengyi stamped her feet anxiously.
"Brother Yang, this is too troublesome."
"Are you bothering me? This is considered 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, and 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've installed it. Once they've installed it, quickly fire a cannon at the back of the mountain to kill those Taijis."
Yang Fan smiled bitterly, "You have a good idea. I am not a fool. I 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 it was hard to tell the difference. The short and thick ones were howitzers, and the thin and long ones were cannons. But he was not stupid enough to make such a dirty joke with a girl. I guess Zhang Fengyi would react when she realized it.
He immediately raised his pink little fists and gave this disciple a pair of panda eyes.
"Look at the mountains in the distance. If you connect the high points, it becomes a line, right." Yang Fan pointed at the distant mountains and said. "In military topography, this kind of line is called a mountain ridge line, or ridge line for short.
The ridge line is the line formed by connecting the highest points of the mountain range, which is the top line of the ridge. It is usually also the watershed line or watershed. The 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.
Cross the city wall to 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 notebook from her arms, took out a small writing brush, stuck out her pink tongue, licked it with her tongue, and recorded it at high speed.
"I understand, Brother Yang, those Taijis have gone behind the hillside. That is to say, they are 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. It seemed that she did have some talent for military affairs.
"Yes, behind the ridge is a reverse slope. Cannons cannot hit it. If the enemy is building fortifications on the reverse slope, it will be very difficult. The artillery cannot destroy it. If the infantry rushes over, it will be attacked from behind by the enemy relying on the reverse slope fortifications.
