The reason why artillery is heavy is because when the explosive charge is detonated, the pressure in the front and rear of the barrel is different.
The pressure is greatest at the rear of the gun, and the closer it is to the muzzle, the smaller the pressure is.
Therefore, when casting, the back should be thick enough and the front should be appropriately thin.
The weird thing about the Fran cannon is that the ammunition is loaded in the sub-gun, which means that the maximum pressure is borne by the sub-gun. In this way, the barrel can be made very thin.
If the gun explodes or is damaged, just replace it immediately. The barrel is connected front and rear, the barrel is thin, and the heat dissipation is super good. These all lead to a high rate of fire and a duration of continuous firing.
Generally, Folang machine guns are equipped with five blunderbuss.
Before Yang Fan went on the expedition, he brought all the artillery in the Beijing camp and the firearms from the warehouses of the Ministry of War and the Ministry of Industry. All were tested with twice the charge, and those that did not explode were taken away. Those that did explode were returned to the furnace and remade.
Yang Fan used the scraps of the blasted barrels to cast a large number of muskets. Twenty muskets were prepared for each Fran cannon. All of them were loaded with ammunition in advance. Just plug them in and fire.
Su Litang knew that at this time, there was no way to stop the attack. He could only bite the bullet and rush out. He could only pray that the Ming army's guns would soon be exhausted.
Bang bang bang! Another round of Fran cannon fire, and a large number of people rushing in front fell again. More than a hundred people were killed or injured.
Yang Fan put down the telescope and knew in his heart that there were still too few firearms in Jingying.
There are twenty-two infantry regiments, and each regiment only has eighteen artillery pieces. This is incomparable to the 500 bronze-fired cannons with 3,600 people in the chariot camp. Under the firepower of the chariot camp, ordinary enemies cannot attack at all.
Not coming up. But now, with the three regiments in front and fifty-six artillery pieces, their striking power seems very weak.
Moreover, these artillery are all small artillery, and there is no heavy artillery. Although the caliber of the general cannon and the general cannon are not small, their barrels are short and thick. The weight is not too big. Generally, there are two handles on the cannon. Several people
Use a wooden pole to carry it away with a rope.
As for the three generals, the fourth generals, and the fifth generals, each one is even lighter than the other. The five generals only weigh forty or fifty kilograms, and one person can carry it away by the handle.
The range of this kind of artillery will definitely not be too far. In the naval battle film Mingliang Battle made by Bangzi, their ships are similar to the Anzhai ships in the small book. Note that the cannons are all short-bodied and have handles. They are the generals of the Ming Dynasty.
And the second general cannon, the third general cannon, etc.
Facing the surging Yarkand army from the front, the defenders were very calm. They were shrinking and forming a tight square formation, preparing for a period of cold weapon combat.
As the fighting became more and more intense, they started shouting and then gradually became silent.
Not only fighting, but also marching without saying a word.
A silent army is a terrifying army. It was not until this moment that Yang Fan confirmed that all the hard work he had put in over the past year had finally been in vain. Only such an army can fight tough battles when it is necessary to have time to prepare for the battle, just like eating, drinking, and sleeping.
.
They have no emotions anymore. All they have is obeying and fighting, thinking little and just doing it.
The officers and soldiers of the Beijing camp looked indifferently at the enemies rushing up in front of them. Their faces were expressionless. They just followed the whistle and the officers' shouts, automatically formed a tight formation, clenched their weapons, and waited quietly.
Follow the order.
The Folan cannon continued to fire at a rate of less than ten seconds, constantly bombarding the enemy.
Every very short time, a row of flames and gunpowder smoke spurted out, and the hot lead balls directly penetrated the Yarkand people. The cavalry of more than a thousand people who rushed in front suffered heavy losses because they rushed so fast and ran away.
In front. Moreover, the cavalry target is large and easy to aim at.
The artillerymen naturally gave priority to greeting them.
Each round of shelling resulted in nearly a hundred casualties. In the blink of an eye, ten rounds of shelling had been carried out. Nearly a thousand people fell on the charging road.
The Yarkand people finally rushed within the range of the bows and arrows. Their front team held small bucklers and scimitars. The officers and soldiers behind them started shooting with cavalry horn bows.
At this time, the distance between the two sides has reached 150 meters.
"Steel crossbowman, fire." Yang Fan ordered.
The Beijing camp has purchased a certain number of steel crossbows, and each regiment has about a hundred steel crossbows. These steel crossbows are made of bow arms made from scrap car shock-absorbing spring steel sent from the Xincheng Arsenal.
At the same time, a pulley block boosting system and a ratchet winding are installed inside the receiver. As long as the winding lever on the side of the receiver is pulled down from the front to the end, the winding is completed, similar to the charging handle of a rifle.
Three infantry regiments and two cavalry regiments, with a total of 500 steel crossbows, also started firing.
Whoosh! Five hundred crossbow arrows also flew into the sky.
Crossbow arrows are different from bows and arrows. Crossbow arrows do not have tail feathers. The tail feathers of the bow and arrow play a role in stabilizing the ballistic trajectory, so the arrows fired will be more accurate.
However, everything comes at a price. After the tail feathers stabilize the trajectory, they will also produce great resistance, resulting in a decrease in speed and a reduction in range.
The crossbow arrow has no tail feathers, is very short, and is made of pure steel. The pulling force of the crossbow is much greater than that of the bow, so the crossbow arrow has a faster muzzle velocity and a higher speed. It has high momentum and its armor-breaking ability exceeds that of the bow and arrow.
Some of these crossbow arrows have drilled holes in the arrowheads, which make a screaming sound when flying.
The purpose is to frighten the enemy. This strong psychological suggestion is very terrifying when dense crossbow arrows are fired. People will naturally dodge, thereby disrupting the enemy's military formation. Once the formation is disrupted, the impact of our infantry formation will begin.
.
Only by being able to break the formation can you be trapped in the formation.
The screams fell from the sky, which immediately shook the morale of the attacking Yarkand infantry. Many people saw these thrown black dots and naturally knew that they were arrows from crossbows. This era was not without dynamite.
Whoosh whoosh, after a dense sound, a large number of bows and arrows fell on the infantry array of the Beijing camp. When the Yarkand people began to bend their bows, the Beijing camp raised their shields. They also wore plate armor and helmets
.
In order to save money, Chongzhen bought bucket helmets for the soldiers. He bought pig-head helmets for Xiaoqi and Zongqi. He bought bird-beak helmets for the hundred households of the sentry captain. And the battalion commanders were all direct descendants of Xungui.
They are equipped with the most protective frog-mouth helmets produced by Yang Fan.
Although the frog mouth helmet looks very funny, the protective power of this helmet is the pinnacle of the cold weapon era. Its performance is very beneficial.
The dense bows and arrows landed on the shields, plate armor, and helmets. Apart from a jingling sound, they had no effect.
The crossbow arrows that screamed and fell from the sky directly penetrated the chainmail armor of the Yarkant officers and soldiers.
Their helmets were riveted iron sheets, and their armor was half-mail chain mail with a hood, with the lower edge at the knees. They wore a chain mail hood on their heads, and then put on an iron helmet.
However, when these crossbow arrows fell, the iron helmet was directly penetrated, and the chainmail hood inside was not able to block it. The short crossbow arrows, only thirty centimeters long, penetrated directly through the head.
As for the chain armor on the torso, it penetrated directly. There was a loud popping sound.
As Suli Tang's war horse whined, its right front leg was penetrated by a crossbow arrow. The war horse suddenly knelt down, snatched him out of its mane, and threw him directly to the ground.
Suli Tang quickly dodged to avoid being trampled by the horses behind him, and took the opportunity to roll into a small pit nearby.
