"Don't pick it up anymore. Hurry up, pack your things, lead your horses and go back. The enemy's large force has arrived." Wang Hao shouted loudly.
The boys who were looking for souvenirs immediately dispersed and quickly beheaded those who were beheaded.
The one who leads the horse leads the horse.
They ran back in a swarm.
At this time, trenches had been dug on the hillside.
With a depth of one meter, the excavated soil was beaten into a parapet of 50 centimeters high, forming a U-shaped ring fortification.
The engineers were exhausted and dug 75,000 holes outside.
On average, one person dug out 2,500. Although it was just a matter of stepping on it, the Luoyang shovel dug out one.
But if one person steps on it 2500 times,
This job is not easy either.
They also had to lay a layer of barbed wire ten meters in front of the formation. After all was done, they were almost exhausted. They all retreated to the back to rest.
The artillery also set up emplacements for five three-pound guns.
According to artillery drill regulations,
Use straw bags filled with soil and build a one-meter-high parapet to protect cannon ammunition and personnel and prevent enemy bows and arrows from being thrown.
The artillery carried a total of five three-pound cannons. Because of their light weight, these cannons could be towed by a single livestock draft horse, or pushed and pulled by humans.
If it is made of bronze, it is usually about 500 kilograms. Yang Fan's three-pound cannon is made of cast steel, which is stronger and lighter than copper.
Because it is strong enough, the barrel wall is made thinner, further reducing the weight.
In addition, in the Roses and Guns group, netizens asked a professional to optimize the design and successfully reduced the weight to 300 kilograms.
Moreover, referring to the Japanese Type 92 infantry gun, the entire gun can be disassembled. After disassembly, each component does not exceed 30 kilograms.
One person can resist walking. The heaviest barrel can be carried by four people using wooden poles.
It can be carried on horseback or carried on people's shoulders, which greatly enhances mobility.
This master of design is so awesome. He specifically stated that this was mainly due to the needs of mountain combat.
In the later period, if Yang Fan went to Liaodong to fight slaves, his troops would really need light artillery that could operate flexibly in mountainous and forested areas.
Historically, the range of this type of gun was generally around 480 meters.
Because Yang Fan's cannon is made of steel, its strength is increased, the barrel is lengthened, it can be charged with more charges, and its range is increased to 750 meters.
In order to improve the range, many technologies have been adopted, including installing lead belts on top of spherical cast iron solid bullets, which are used to deform and block the gap between the shell and the barrel during firing to prevent air leakage.
For the shotshells, small steel balls collected by Erluzi from modern scrap collection were used.
A shot of shotshell contains a thousand small steel balls. When fired, it can create a 300-meter-long fan, which can be used to sweep across cavalry and infantry.
In order to increase the firing speed, the ammunition was directly wrapped in silk and made into fixed ammunition. When using it, the artilleryman just took it out of the wooden box without weighing the gunpowder and stuffed it directly into the muzzle.
There is no need to adjust the range, because it is a short-range gun. It usually hits enemies within 500 meters directly.
If you must adjust the range, then use several small propellant packets as needed and adjust the muzzle pitch angle to accurately adjust the range.
Silk is not cheap in the Ming Dynasty, but silk has one advantage. It is completely flammable and leaves very little residue.
If the ammunition is packed with paper, the barrel of the gun will need to be cleaned about thirty times. The barrel of the artillery will need to be cleaned about fifty times.
On the ever-changing battlefield, ceasefire is no joke. The longer the chamber clearing time is, the better it is for the battlefield.
Gu Xie There is another obstacle to increasing the rate of fire, which is the overheating of the gun barrel.
On the battlefield, if there is enough ammunition, it is common for the artillery to fire the barrel red when the enemy is in an emergency.
Generally, in this case, for the sake of safety, you must stop shooting. There are two reasons. Both are related to the explosion of the barrel.
One is that an overheated barrel will ignite the propellant, rendering it unusable, or even causing the barrel to explode because the propellant does not burn linearly and gradually.
In addition, when the barrel turns red, the strength of the metal decreases significantly, which may cause the barrel to explode due to the decrease in strength, or the barrel may become soft and deformed, changing the ballistic shape, causing the shell to get stuck and explode.
No matter which situation occurs, such a cannon will be useless.
One of the methods Yang Fan took was to use steel with a higher melting point to cast the gun barrel.
The other is to learn the Maxim water-cooled machine gun method and use liquid cooling.
That is, a thin iron sleeve is added to the outside of the barrel. There is a cavity in the middle, and water can be poured into it. Then the low temperature of the barrel is kept through the evaporation of water.
The sleeve and water undoubtedly increase the weight, but this is a helpless trade-off. Remove it for low-intensity combat and install it for high-intensity combat.
The master of design even considered the situation of fighting in cold northern areas, where there is no water, only ice and snow. He designed a huge water inlet funnel, which can directly shovel the ice and snow in with a shovel.
The artillerymen were even required to bring a set of Luoyang Shovel pressure well drilling equipment to facilitate access to water at any time. This also made it easier for the troops to use water. After all, humans and horses need water. They also need water for cooking, washing clothes, and bathing.
In order to avoid waste, such as fighting in the Gobi desert, the master also designed a steam duct and condensate water box. This is also imitated from the equipment of the Maxim machine gun. It is used to reduce the evaporated water vapor into water through the duct condenser.
,recycle.
Artillery instructor Peng Warlock, today is the first time he has led the artillery squadron to participate in the battle. This artillery unit, like An Sanxi, is an officer training team. It is full of officer seeds.
It was their first time to participate in the war. They were familiar with the regulations and drills over and over again, for fear that they would make mistakes that they shouldn't make.
Today, Sancha Post has become a well-arranged preset battlefield according to Yang Fan's instructions, just waiting for the enemy to come.
From bottom to top, the first level is the outer hole, specially designed to prevent the enemy's horse legs from being broken.
The second layer is the naturally formed Tur River, which can effectively slow down the impact speed of enemy cavalry. The engineers also secretly laid a layer of barbed wire in the river.
This sinister idea was thought up by Hou Shengwu, the leader of the engineering team.
The third level is the trenches and earth breastworks, where the musketeers take turns firing in two levels.
The fourth level is the artillery team's emplacement built with sandbags. Because the muzzle of the gun is higher than the infantry in the trench, it can fire at will without worrying about hurting the infantry.
On the fifth floor, which is the top of the hill, a command post was built with sandbags and covered with a tarpaulin. An Sanxi and Huang San commanded here. They were commanding from a high place and had a good view, allowing them to observe the surrounding situation in all directions.
"Here we come. It seems that there are more people than we estimated. It's not two thousand, but about 2,700 or 800 people." An Sanxi put down the telescope and said.
Huang San nodded and said: "There are some discrepancies in the intelligence, which is a common thing on the battlefield. We have already digested this. It's not a big problem."
In the distance, on the horizon, Irgun Taiji came from a distance with a large group of people.
He knew that except for a hill in Sanchagang, there was nothing to fight. In his opinion, there was nothing to fight in this battle. The cavalry just pushed over and trampled these arrogant bastards to death.
Alslen looked at the hill in the distance and frowned suspiciously.
