Yang Fan and others quickly grabbed the various handles around them to prevent them from falling. They supported Zhang Wudian with the other hand. But the old man reacted very quickly and grabbed the handrail immediately.
"Let's see what's going on." Yang Fan said.
This was the first time a ship had stopped sailing since it started sailing. Huang Hao immediately led people to rush to the bow of the ship to check the situation.
"Master, the bow of the boat ran aground. The river bottom here is both deep and shallow. When we turned just now, the rudder was pushed too hard and it washed up on the shoal." Huang Hao ran back and said after a while.
This is quite normal. The depth of the bottom of such rivers varies greatly. Some are less than one meter deep, and some are dozens of meters deep. It's very outrageous.
The main channel of the Yellow River is not much better. It is more than ten meters deep here in Linhe City. There is a section near Yinchuan that is 180 meters deep. The depth near Lanzhou is not that great. It is back to more than ten meters deep. The Yangtze River
There is also a situation in the upper reaches of the Sichuan River. In the lower reaches of Chongqing, there is a dry period where the depth is only 3.5 meters, while another section is more than 100 meters to more than 200 meters deep.
Zhang Fengyi suddenly became a little nervous. She grabbed Yang Fan's arm tightly with her small hands and asked, "Brother Yang, we won't be trapped here. There are more than 50,000 Mongolians here."
Yang Fan smiled and said: "It's okay, don't worry. At least half of the 30,000 people in the city were burned to death. The remaining camps were scattered, with only three to four thousand people each. They were frightened by heavy artillery and machine guns.
I don’t dare to come closer.”
Huo glared at her daughter and warned her not to hold on to Yang Fan's arm.
Zhang Fengyi's face turned red and she let go of her hand.
"Uncle Dingyuan, if it is stranded, I remember that it seems that it needs to be stretched to pull the boat into the water again." Zhang Wudian asked.
"No need, we are a powered ship, we don't need to pull fiber." Yang Fan's face was calm. "Reverse the car and pull out the bow."
When entering an area with tributary rivers and forks, stranding is a common problem.
When designing a shallow-water heavy gunship, there are some considerations. One is that the draft is no more than one meter deep when lightly loaded, and no more than 1.5 meters deep when fully loaded. The other is that the transmission system is designed with a reverse function, that is, the propeller is reversed.
Rotate, then reverse out when the bow of the boat runs aground.
"Is it a reef or a beach?" Yang Fan continued to ask.
"It's a shoal with some pebbles. The bottom of the boat should be fine," Huang Hao said.
Yang Fan felt relieved. The cement ship was also afraid of colliding with the rocks. After all, cement is much heavier than wood, and the hull is very thin. If the hull is too thick, it will take up too much load capacity. It is not cost-effective.
Therefore, the thickness of the four sides of the cement ship is different in the design. The front part of the hull is thicker to prevent collision. The sides of the ship are thinner to reduce weight. The thickness of the stern is between the two.
Woohoo! The whistle sounded again.
As the captain Du Xiaoyun gave the order to reverse the vehicle through the microphone in front of the bridge. After hearing the order twice, the chief engineer in the engine room immediately moved the handle and let the gearbox transmit power in reverse. The propeller at the stern stopped.
once, and then quickly rotated in the opposite direction.
The reason why the command needs to be repeated is because in a fierce battle, if the command is only heard once, it is easy to mishear it. Repeating the command will greatly reduce the probability of error.
Similarly, after receiving an order, you must repeat the receipt twice and repeat the content of the order.
In this way, both parties will know that the other party has received the order accurately. The responsibilities of both parties will be clarified.
As the propeller reversed, the water at the stern of the ship was muddied, and a huge force pulled the gunboat back.
The sound of caracara came from the bottom of the ship. Then it retreated little by little and returned to the main channel. The captain immediately turned the rudder, pointed the bow of the ship towards the main channel and drove forward.
After re-entering the main river, face the camp ahead and continue moving forward.
The high ground in this camp was where Gushi Khan, Hara Huci and others stood on horseback to observe.
"No, that boat is coming towards us." Dalai Tush exclaimed.
"What kind of thing is this? On the grassland, the eagle on our grassland was actually chased by a bastard in a river and fled in a hurry." Hala Huci said depressedly.
They have received too much stimulation today.
From the morning, they were driven out of the blazing city by fire. They watched helplessly as the fire burned all the food and grass. Then the infantry and cavalry were beaten to pieces by a boat.
Now it was actually a boat galloping in the river, chasing the cavalry and camps it discovered.
They didn't know what to say about how such a big and tall ship could move freely in these tributaries.
Gushi Khan's face turned livid, and he said: "We are not marmots on the grassland. We only know how to crawl into holes when we are in danger. If you want to leave, you can leave, but I won't leave."
He was very angry today. More than 50,000 people were actually chased and beaten by a boat.
"We don't want to escape, but we have no way to restrain their firearms. The cavalry can't go into the water. They are in the water, so we can only be beaten passively." Hala Huqi said helplessly.
Speaking of being fierce, the Dzungars are much more fierce than the people from the Heshuote tribe. But the Dzungars are not stupid. They can beat you at will, but there is no way to fight in a battle where you have no way of hurting them.
"You can try using a shield car." Dalaitus suddenly said, "It's the kind where multiple layers of wooden boards are erected on the front of the Lele vehicle for the soldiers to push forward. The wooden boards are used to block bullets and cover the soldiers hiding behind.
Fire muskets, the river here is narrow, let the soldiers carry the raft and throw it into the water so that you can climb onto the boat."
This method has been used by all departments.
When they attacked the castles of other peoples in Central Asia, they often used such large shields and shield carts to block the bullets fired from them. Sometimes they were made of rafts made of more than a dozen wooden sticks. Sometimes they were made of multiple layers of cowhide.
Large shield. I also experienced this when using a shield car.
If the shield is too heavy to be moved manually, put it on a cart and push it.
The gunboat continued to move forward. Yang Fan saw the Mongolians arranging their troops on the high ground at the bend of the river.
This is a bit strange. Ever since the Oirat cavalry was defeated today, I haven't seen anyone who dared to stand up. What's even more amazing is yet to come. Yang Fan saw the shield carriages lined up on the hillside, and some were still working hard to build them and were heading towards
Install wooden boards on LeLe car.
He hadn't seen this thing for a long time. The last time he saw it was in Haraqin.
Yang Fan smiled, what use could this thing have?
When the Haraqin people used this thing, it was much better than what the Oirat people used today to modify the Lele vehicle. After all, it was a specially customized shield vehicle. It was comparable to the Jiannu one. It was made of three-inch thick hardwood plus sand and gravel.
layer, plus three layers of quilts, then another layer of sand and gravel, plus three inches of hardwood.
But in front of his own copper-haired cannon, it was just like paper. Apart from providing flying wood thorns to increase the killing range, what was its use?
In front of heavy artillery, all shield defense methods are useless. They are all rubbish.
It's even more funny to see the several layers of wooden boards put up in front of these Lele vehicles to block the artillery. It's not a problem to learn to block a matchlock gun. But in front of the single-head bullet of the Gatling cannon, it's better to just sleep.
.
At a distance of two hundred meters, the kinetic energy was enough to smash their broken shield vehicle into a pair of wooden slag.
