Zheng Tu's team had already equipped themselves with air rifles equipped with bayonets. The five of them were hiding in a partially collapsed building.
After fighting for six days, the Jiannu slaves also imitated the traitor. They put the cannons at the top of Zunhua City on wheels and used them to bombard the barricades. Heavy artillery bombardment of barricades is really effective. Those who were in the Grand Commune in Paris were
Cannons were used for barricade warfare. They were very easy to use and were later adopted by Western European countries.
This is the experience gained from the bloody lessons of Jiannu. In these seven days, the Han army and the Mongolian tribes were beaten miserably. Every barricade became a battlefield for the two sides. If there was not enough gunpowder, the explosive packs alone would be enough for them.
Drink a pot.
These militiamen and strong men tied the explosives with rawhide, covered it with steel slag, and then tied it with rawhide. Then they inserted the fire tube. An explosive bag was ready. When a large number of Mongolian and Han military flags rushed up, one
The explosives were thrown over and the body was left dead with broken limbs and arms.
They are now afraid of being hit by the explosive packets rolling down from the barricades and the tops of buildings.
These people hid behind the ridge of the house, and even their heads were not exposed. They pushed the explosive package and rolled it down. Then there was an earth-shattering explosion, and steel slag flew everywhere. People in the narrow street could not find cover at all.
Every place was blown up to the sky.
Sometimes, they were attacking a barricade. Han Junqi set up a wheeled Franco machine gun and fired directly at it, finally suppressing the militiamen and strong men on the barricade. Suddenly, behind the ridges of the buildings on both sides of the street,
Someone pushed down an explosive bag with a smoking fuse.
Then, people in an alley were blown up into the sky.
Huang Taiji became anxious and ordered Li Yongfang to find a way as soon as possible.
Because he was the only one who knew firearms. Li Yongfang had no choice but to gather together the captured workers and masters from the steel workshops outside the city, and use the captured coke, coal, charcoal, pig iron, and iron ore to use the blast furnace in the city.
, began to cast mortars.
Because in this era, no matter in the East or the West, mortars are the only effective siege weapons.
This kind of artillery has a very large caliber. During the Hongwu period, mortars with a length of one and a half meters and a caliber of half a meter were cast. These guns were installed on heavy wooden bases. They fired in the same high-trajectory way as mortars. The range was generally 300 meters.
About meters.
Cannonballs use stone balls with a diameter of half a meter and weigh one to two hundred kilograms, or even three to four hundred kilograms.
There are more than 20 bronze-haired heavy cannons at the top of Zunhua City. Wang Yuanya only cared about martyrdom for his country and did not destroy these heavy cannons immediately. These heavy cannons were also pulled by Li Yongfang to bombard barricades and buildings.
There was also no shortage of gunpowder. Mines were indispensable without gunpowder. When Jiannu raided the mines of civil servants, they seized a large amount of gunpowder. These gunpowders were military gunpowder sold privately by civil servants of the Ministry of Industry. They stored it in the gunpowder depot of Wang Gong Factory in the capital.
The imperial court stockpiled gunpowder, roped in the caretakers, and sold it privately to the mines in Zunhua for profit.
Because these mines also have civilian backgrounds, this is tantamount to an under-the-table deal between civil servants.
After the slaves captured these mines, these military gunpowder also became trophies.
Li Yongfang quickly came up with countermeasures. One was to use the 23 captured heavy artillery pieces to bombard the barricades in the shanty towns. More than 20 pounds of artillery shells could penetrate these tattered barricades. A large number of people guarded the barricades.
The people behind were beaten to pieces by the penetrating shells.
The Jiannu infantry pushed a heavy artillery piece, and were protected by two carriages on both sides. They advanced little by little, clearing one building after another.
At the same time, the Hongwu bronze cannons that were urgently cast were also put into use. They were used to bombard private houses from high ballistics. Li Yongfang was anxious. He believed that only by razing these dilapidated houses in the shanty towns to the ground could we truly occupy this place and obtain the adjacent industrial zone.
High walls of opportunity.
The large number of troops that had rushed in before were shot from above, below, left and right, and were stabbed to death with spears by the militiamen and strong men who suddenly rushed out. This non-linear combat mode without front and rear made Jiannu extremely uncomfortable. They just
There has never been such a battle.
Zheng Tu's team consists of five people, captain Zheng Tu, riflemen Cao Sanzizi and Qin Dangdang. The three of them are young and strong. They are equipped with three air rifles and carry a thirty-centimeter bayonet. Wu Xiazi, the fortune teller, and Liang, the vegetable seller.
Sanqiu holds two double-barreled flintlock muskets.
They were hiding on the third floor of a half-collapsed building, looking at the street below through the gaps and cracks.
A red soldier with fifty Han army flags and gunners pushed a heavy cannon, shouting and struggling to push forward from the street below. Some Han army flags were busy picking up the rocks and bricks in front of them.
Get up, move the broken wooden beams away, and clear the way for the heavy artillery to pass.
More than a hundred Mongolian soldiers in the back were holding cavalry bows and were ready to shoot at the defenders who had exposed their heads on the barricade opposite. Unfortunately, the militiamen on the opposite side were not stupid either. They would not show their heads at all and reserved them when building the barricades.
Shooting port.
The muskets in front were banging! They kept spitting out flames towards Jiannu, but the carriage could basically block the shots of these muskets. Then a stone was moved away, revealing a black muzzle behind it. This is steelmaking.
A newly cast three-pounder cannon in the factory.
The slaves captured the ironworkers and could cast cannons. Of course, cannons could also be cast in the industrial area.
The cannon can be cast very quickly. Once it has cooled down on the same day, it can be used the next day.
Then the second and third stones were moved away, revealing the muzzle of the three-pounder cannon.
Immediately, the three cannons spurted out flames. Three lead balls flew out and hit the cart accurately at close range. The wooden shield of the cart was shattered. The sand and wood blocks inside flew backwards. Sharp and sharp.
The wooden slats pierced the bodies of the soldiers behind the car. For a moment, a large number of people fell to the ground, wailing in pain.
Immediately, Jiannu's heavy artillery also opened fire. There was a loud noise. The small building where Zheng Tu's team was hiding almost did not collapse. The huge kinetic energy gave the cannonball great power. The cannonball directly penetrated the barricade, and for a while, sawdust flew and piled up.
The broken tables and chairs were thrown up, and all the debris behind them flew up, creating a V-shaped gap in the middle of the barricade.
More than a dozen defenders hiding behind the barricade were beaten to pieces. The three three-pound cannons also staggered and could not be fired for a while.
Jiannu shouted, and the Mongolian soldiers immediately swarmed over and tried to rush in through the gap. After all, it took seven or eight minutes to load heavy artillery. It was not easy to launch heavy artillery in this era.
The defenders had a general flag, and there were about 20 people left. They stood up unsteadily, carrying the air rifle with the bayonet, climbed to the top of the barricade and faced the outside, firing out 30 rounds of gas per tank.
