If you are careless, when the time comes to use it, if the hemp rope on a floating bridge that is several feet long is not strong, the bridge will be destroyed and people will be killed."

"I don't know how to judge the quality of hemp rope, but do you two know?"

Liu Bei thought for a moment and said, "The hemp rope with many and dense strands is the best."

Seeing that Liu Bei was interested, Li Mengxi handed over the quality supervision of hemp rope weaving to Liu Bei.

Liu Bei smiled and agreed, "Just in time, Yun Chang, a pontoon bridge requires two long ropes. You and I will lead people to braid one each to judge the quality. How about it?"

Guan Yu smiled and said, "Just follow my brother."

Well, although the rebels have not yet encountered a situation where they need to build a bridge, they have already begun preparations for building a bridge.

Sufficiently long and strong enough hemp ropes were being woven. Although we didn’t know when we would need to cross the water to build a bridge, we must have had more than one long rope in the army when we encountered them.

Only by being prepared can you be safe.

More importantly, in the past, it was Li Mengxi who thought of the relevant technical details, but now Yuzhou thought that large ships and pontoons might also be needed when marching in the future. This was Guan Yu's idea.

The wisdom of one person cannot match the wisdom of many.

Bai Tian mentioned that each hundred-man team in the army can be equipped with one or two fishing nets and one or two grappling hooks. These soldiers with special equipment may be called technical sergeants.

Tonight, I thought about the hemp rope that can be used to build bridges. Hemp rope is different from fishing nets and grappling hooks. A coil of hemp rope that is tens of feet long weighs dozens of kilograms. It cannot be carried by a single soldier.

.

If the grappling hook is a "platoon" level tactical auxiliary equipment, and the fishing net is a "company" level auxiliary tool, then the tens of feet of hemp rope used to build the bridge is at least a battalion level equipment.

The extremely heavy hemp rope is of no use if placed among the centurions.

Therefore, the ability to build pontoon bridges can be delegated to teams of 1,000 people. That is, each team of 1,000 people must have the ability to build pontoon bridges independently. That is, each team of 1,000 people must carry at least two hemp ropes dozens of feet long.

.

The remaining problem is that to build a pontoon bridge, you must first pull the rope to the other side of the river bank. First, you must send soldiers who are proficient in water skills to swim to the other side with the rope wrapped around their waists.

If the water is very fast, or if it is winter and the water temperature is very low, swimming soldiers may easily be in danger.

It would be fine if a pontoon bridge was built on the river, but there is also a suspension bridge built between two mountains, such as Dangyang Changban Slope. Zhang Fei cut off the suspension bridge, and Cao Cao's pursuers were suddenly unable to pursue him.

You can still swim in the river, but there is nothing you can do if the two mountains separate you.

Li Mengxi was not very familiar with ancient technology. The people who were more familiar with the military technology of the Han Dynasty were Guan Yu and Liu Bei. So Li Mengxi asked how to rebuild the suspension bridge if it was destroyed between two mountains.

"Choose a dexterous person to wrap a rope around his waist, climb over to the opposite cliff, and tie the rope to the mountain on the opposite cliff. Then, like building a floating bridge, use wooden planks and lay them on the rope. In this way, the suspension bridge can be completed."

After thinking about it, he replied.

Guan Yu said, find a few elite soldiers who are good at climbing, like special forces, pull the rope, climb to the cliff on the other side of the mountain, and then tie the rope to a stone or tree on the other side of the mountain, when two parallel ropes come from here

Build it from the top of the mountain to the other side of the mountain, then lay wooden planks on the rope, and it will be a simple and passable suspension bridge.

It is a bit difficult to rely on people to climb over and build the suspension bridge.

Many natural hazards are called natural hazards because they cannot be easily overcome by humans.

There may be a suspension bridge built at a dangerous location. Many people died during the construction of the suspension bridge, and it took a long time to build the suspension bridge.

On weekdays, you can build a suspension bridge by climbing over it by pulling a rope. However, if the military situation is urgent, if there is no engineering ability to quickly build the suspension bridge, it will greatly affect the military's combat effectiveness.

There are natural dangers separating us, but there is no way to overcome them. Even though we have millions of troops, we can only look at the danger and sigh.

If we have strong combat forces but do not have strong military engineering capabilities, it means we do not have strong logistical capabilities, or our logistical capabilities have shortcomings. Therefore, we cannot call it a truly strong army.

Although its military strength is strong, its shortcomings cannot be made up for by its strong military strength.

Insufficient logistics will lead to failure sooner or later.

Just like Cao Cao's 800,000-strong army at Red Cliff, although his army was large, his navy was not good and his army had insufficient doctors.

Because the navy was not skilled, they had to use the iron chain strategy, intending to use the ship as a land, taking advantage of the northern soldiers and horses who were good at land warfare, and avoiding the shortcomings of water warfare. Then, with a burst of river fire, Cao Cao's army was defeated on the water.

Fallen into the sand.

Also due to the shortage of doctors, after the plague broke out, it was unable to control it, resulting in failure.

If Cao Cao had prepared for two or three more years, had made more adequate logistical preparations, and doubled the number of ships, even though the navy would still be no match for Soochow, with its absolute size advantage, he would have thoughtlessly rammed the opposite side with fire ships.

Even if you count the casualties, you can consume the entire Soochow navy.

And if Cao Jun had prepared enough medicines and doctors in advance, the plague might have been suppressed in the early stages of the outbreak. Even if all the ships on the surface were wiped out by the Sun and Liu coalition, there was no need to retreat. They could slowly

Logging continued with shipbuilding.

There are three parts of the world, and Wei is the seventh.

Even if it is just a stalemate across the river, Cao Cao has a large territory, a large population, and can raise more food and grass. As long as there is no plague and he does not withdraw his troops, and the stalemate with Sun and Liu's army across the river lasts for a year and a half, Sun and Liu may not be able to hold on.

Already.

Sun and Liu's 100,000-strong army has been in a stalemate with the Wei army for a long time, which means that the 100,000-strong army is unable to engage in production. At the same time, the rear needs to continuously supply food and grass to the front. With Sun and Liu's size, he will be consumed by Wei.

.

In terms of military strength, Cao Cao fought in both the south and the north, defeating Dong Zhuo, Lu Bu, Yuan Shao, Yuan Tan, and Xianbei. The Wei army was far superior to Sun Liu in terms of strength and quality and discipline of the soldiers, but in the Battle of Chibi
