Liu Xun and Qiao Rui dared to take the initiative to attack Zhuge Jin by relying on the strength of the crowd despite the large losses of large warships, of course, they relied on it.

They also know how much the size of the warship affects the combat power in water warfare.

So before this battle, Liu Xun and Qiao Rui also discussed how to use small boats to overcome big ships, and in the end, Liu Ye, the best strategist under Liu Xun, suggested a specific tactic to Liu Xun:

Torches made of hemp fiber materials are used in large quantities, soaked in tung oil, and then thrown at close range. Even if the combat power of the boat is weak, after all, the position is flexible, the speed is fast, and Liu Xunjun occupies the speed advantage of rushing down the upstream stream.

As long as they are not afraid of casualties, bravely break through, surround and throw torches, and burn the most threatening fighting ships of the Han army, the Yuan army will be very likely to win if it relies on several times the superiority of troops.

However, in the pre-war planning stage, Qiao Rui noticed a problem and questioned Liu Ye, that is, "what if the boat is short and the fighting ship is high, if the torch cannot be thrown on the deck and cabin roof, but falls on the side and bulkhead of the ship, and slides into the water"?

After all, this is like standing on the ground and throwing a torch to burn the house, in actual combat, because of the distance and lack of strength, throwing it on the wall is the norm, and it is much more difficult to throw it on the roof.

Liu Xun also felt that this concern was very reasonable, so he asked Liu Ye to try to solve it at that time.

After all, Liu Ye is the one who can invent the thunderbolt car, and for a moment, the idea of "using a device to catapult a fire can" really popped up in his mind.

It's just that the preparation time is too hasty, and this Battle of Spring Valley is not like the Battle of Guandu, which can be prepared for several months, and the operation is too complicated to deploy.

Moreover, these soils are still expansive soils, especially able to absorb water, and the volume can expand dozens of times after absorbing water - in the history textbooks, it is explained that when Li Zicheng and Zhang Xianzhong rebelled at the end, the poor people at that time "ate Guanyin soil and died", it was because of this swelling characteristic of Guanyin soil.

Of these five fighting ships, the largest one can carry 500 people, which is the ship of Zhuge Jin himself and Guan Yu, and the small one can also seat more than 300 people, which adds up to just enough to load all the 2,000 reinforcements brought by Guan Yu.

As long as the springboard hinges past the highest point, the subsequent natural fall smash can be achieved by gravity.

It's just that this kind of operation is more difficult, and if you don't pull fast enough, the acceleration force will turn into resistance. If you just smash it, you don't have to.

Zhuge Jin originally wanted to go directly to the batter of the Wuya battleship, turn the gangplank into a thick wooden pillar, and then increase the iron cone on his head into a giant hammer, and directly smash and sink the boat.

But no matter how they struggled, there were still a few places on the fighting ship where the fire gradually spread, which made the officers and soldiers of the Yuan army full of expectations, and felt that the sacrifice of their comrades was valuable.

In the process of rushing up, the team was shot and killed many soldiers, but Yuan Jun was driven by the impact of the upstream current, and only rushed with a sullen head, at this time it was impossible to dodge and move, and after being shot, he would turn around and escape, and he would only lose his speed and die even worse.

In the end, considering that the enemy was not so strong and could not shoot the pole so early, Zhuge Jin borrowed the idea of the shrunken version, and combined with the Roman crow battleship, he got an articulated springboard with an iron cone.

Liu Xun also saw that his subordinates could come up with such a powerful thing, so he finally decided to make a desperate bet and bet on all the water armies to fight.

Regardless of whether Liu Yefa invented the dovetail torch or not, the Zhuge family's water army will be on such a high standard of damage management!

In the end, some of the soldiers hurriedly found their spears and scraped them at the torches tied to the side of the ship, as if they were cleaning the walls of the ship with barnacles.

For example, it was written in the later "General Essentials of the Martial Arts" that it was a very common idea for warships and siege vehicles to be smeared with wet mud on the outer walls for fire prevention.

However, the expectant eyes of the soldiers of Yuan Jun had only been revealed for a few seconds.

Then, the crossbowmen on the fighting ship were even able to directly aim at the roll call and shoot the enemy soldiers on the ship that were caught one by one. The conditions are really superior, suitable for jumping gangs to kill, and Guan Yu's foot soldiers did not hesitate to rush over with shields to slash and kill.

The Han army immediately came up with a new coping trick and rushed to the rescue in an orderly manner, but quickly poured a basin of cold water on Yuan Jun's head.

As long as it is confirmed that the number and height of the enemy ships are not as good as his own fighting ships, Guan Yu will rush straight up, and then tie up the opponent with a springboard to prevent him from running, and then let his own sword and shield soldiers rush over and slash - Rome relied on this trick to kill the Carthaginian fleet back then.

In particular, the few dovetail torches hooked to the side of the ship were very tricky and hooked not far above the waterline, and the soldiers on the boat could not reach them by their hands and feet, and could not push the torches into the river.

"Quack—"

He had the craftsman hurry up by driving a bifurcated spike into the tail of the torch, and then hammering the bifurcation into a hook.

Both sides were big ships, and each had its own casualties in the fight, and Gan Ning and others relied on their exquisite command and good at water warfare, and only with their hard qualities did they have a slight upper hand.

Second, the tonnage of ships needed to shoot the pole is also relatively large, and the current 500-person fighting ships are forcibly a bit top-heavy.

Of course, when Zhuge Jin first had this bold association, he was not sure, but this kind of thing is easy to do scientific experiments.

The grass-roots officers at the level of commander and leader of the boat team were hoarse and exhausted their morale, and when one of the oarsmen fell, he ordered another comrade to go to the top, lest the boat lose speed and be easier to aim.

Yuan Jun's boat turned around and retreated upstream without hesitation, seizing the road and fleeing.

Several knowledgeable officers of the Yuan Army suddenly despaired, watching all this up close, and directly doubting their lives.

Zhuge Jin is a modern person after all, and of course he must govern the army from the perspective of what he is best at, the most suitable for him to play, and the most room for improvement.

The army pays attention to medical and health care, and the navy army grasps the repair of damage management, and this is the only way to improve combat effectiveness that cannot be wrong in any era.

He even ignored the fact that the battle was still fierce, and personally ran back to the most heavily protected cabin on the ship, and asked Zhuge Jin, who was drinking tea in the cabin to supervise the battle, this question. He also took a sample of a dovetail torch that had just been extinguished in his hand, and presented it to Zhuge Jin with both hands.

Liu Xunjun's ships were pierced by an iron cone springboard, and although it did not damage the structure, there were less than a hundred soldiers on each ship. Being stuck by a fighting ship of three or five hundred people, while condescendingly firing arrows and shooting, weakening and then jumping off the ship to kill, it can almost form a crushing with more and less every time.

With the addition of Guan Yu, the collapse of Yuan's army gradually began to snowball.

Anti-damage, output, milk, these three roles, obviously milk is the most suitable for modern people to play, and the ancients were the most neglected, so strengthen milk first.

……

With the conquest of the Three Kingdoms in the late Han Dynasty for nearly a hundred years, in the middle and late Three Kingdoms, the rushing car began to evolve into the kind of slope crest shown in the Age of Empires game, which allowed the torches and rolling wood stones thrown on it to slide and "ricochet" on both sides.

Moreover, if a torch is dropped on the deck of an enemy ship, it is still easy for enemy soldiers to walk around, pick up the torch and throw it into the water at the first time.

Guan Yu consulted Zhuge Jin and further refined the idea of fire prevention, and soon began to deploy an attack.

"Although the casualties were not small, they finally broke through the blockade of Ganning Taishi Ci and killed in front of the enemy fighting fleet. This time, I took out all the tung oil reserves in Lujiang County, which cost a lot of money, and I also gambled on the secret weapon of the dovetail torch, but as long as we can order all the fighting ships of the Zhuge family, we will win! ”

However, as Liu Xun made a quick decision, he took out most of his own big ship combat power and restricted Gan Ning's activities. And further use the remaining big ship combat power to temporarily entangle Tai Shici at the cost of losses.

As the flags of the Yuan army were lowered one by one, Liu Xun and Qiao Rui were keenly aware of the impossibility of this battle, and hurriedly ordered the whole army to withdraw their troops and flee for their lives.

I saw a group of soldiers on standby who had nothing to do on the fighting ship, suddenly carrying buckets and mops, rushing to the burning place of the torches, first pulling out the torches and throwing them into the river, and then splashing buckets of gray-white things that looked like thin mud on the location where they were ignited.

The problem is, something so defying common sense, it just happens!

Therefore, in the original history, in order to resist the siege equipment such as rushing cars and digging wooden donkeys on the top of the slope, the torches of the defending side also evolved into "dovetail torches", and the tail was hooked with an iron hook to the top of the slope and continued to burn.

Zhuge Jin has more chemical knowledge than the ancients, and he knows that the thermal stability of silicate soil is better, and the kaolin and Guanyin soil of porcelain are silicate soils. And Yuzhang is the Jiangxi of later generations, suitable for the production of porcelain, such soil is everywhere.

It is equivalent to that the attacker is still using the arson technology that has just been upgraded from LV2 to LV3, and Zhuge Jin is already using the fire technology of LV5 to shield it.

Yuan's army was intercepted by Gan Ning's ship, and at the same time, Gan Ning moved flexibly and kept a distance from entering the range of throwing torches, so Yuan Jun fell into the most embarrassing state and paid some casualties.

At this time, another small toy that Zhuge Jin had prepared for the navy in the past few days was used - it was a springboard facility that was fixed on a large fighting ship and had a sharp iron cone on its head.

"I didn't expect Liu Xun to attack with fire," Zhuge Jin's answer was very crisp, and as he spoke, he took the dovetail torch and looked at it a few times.

Finally, relying on this bloody bravery, after paying an average of two or three small walkers who were killed or injured by the fighting ship, the other walkers were able to rely on the sacrifices of their comrades and forcibly rush to the range of throwing torches.

These gangplanks are also not very long, just the same width as the fighting ship, so that they can usually be placed flat on the deck in turn, instead of being erected, and have little effect on the rise of the ship's center of gravity.

Guan Yu thought that Zhuge Jin was being modest, and hurriedly said quickly: "Impossible! If the gentleman hadn't expected it, how would he have asked us to prepare porcelain clay slurry to extinguish the fire? ”

Zhuge Jin's batch of goods is based on the advantages of the warships from the Sui and Tang dynasties to the Song Wuya in later generations, directly like the head, tail and limbs of a turtle, two springboards were also installed on the sides of the battleship, and levers and coaxial labor-saving pulleys were used to ensure hinge and smash down.

In the end, Liu Ye gave up those whimsical ideas, and instead made some small improvements with a flash of inspiration.

Liu Ye needs to use a small boat to throw torches to burn the big boat today, and this kind of improvement can be regarded as a crooked attack.

"Don't be afraid! Rush up! Throw the dovetail torch and burn the fighting ship! ”

Zhuge Jia's fire prevention technology has been upgraded many levels ahead of the arsonist side.

There is a newly invented dovetail torch for setting fire to a big ship, but there is no place for it.

Therefore, a smart person like Zhuge Jin is easy to think of as a bypass: using expansive silicate soil to form mud to extinguish fires can also prevent water from meeting grease alone in the form of overflow, causing oil to float in water. In this kind of mud, water and mud are fully mixed and adsorbed together, which not only improves the specific heat capacity and cooling effect, but also has fire resistance.

In the hearts of Liu Xun and Qiao Rui, the hope of victory rose again.

After resisting Yuan's strongest wave of output, the Han army quickly launched a counterattack.

Now, Liu Ye's means have been exhausted, and the fire attack is completely ineffective.

As a result, the enemy who dared to approach within two feet of the fighting ship had to distance himself to avoid being nailed and killed.

"Is this the effect of porcelain clay slurry to extinguish fires? Mr. Ziyu, didn't you have long expected that Liu Xun would try fire attack? And will use such a vicious fire attack weapon? ”

During the pre-war preparations, he himself sent people to Poyang County (Jingdezhen) to dig up a lot of porcelain clay to do mud and grease fire experiments, and found that it could perfectly extinguish the early oily arson, and he was relieved.

Now this new type of torch that can be hooked to the outer wall of the ship's side is very likely to be hooked out of the reach of the enemy's hands, but it will continue to stick and burn for a long time, which is perfect.

Then dozens of dovetail torches spun and flew out like grenades.

Yuan Jun, who had thrown the torch at a very close distance, walked directly like a fly swatting a fly, smashed so that he couldn't move, and was pierced through the hull by an iron cone and nailed together.

……

Guan Yu's army is inferior to Gan Ning and Taishi Cibu in water warfare, so letting them sit on the largest boat, with the lightest bumps and the least seasickness, is conducive to giving full play to their combat power.

It's like when I govern the army, the first to grasp the medical and health conditions of the marching camp, drinking water must be boiled, and the wounded must be debrided and bandaged. These things, no matter what kind of enemy the enemy is and how the enemy fights, we should do it ourselves. ”

Mr. Ziyu teaches some avenues that do not change and should be changed, and they can be used in any situation.

Although this height difference is not as big as shooting from the city wall, it is at least equivalent to shooting flat from the window of an ordinary two-story building, and the advantage is obvious.

Historically, in the late Han Dynasty, the siege and vehicle weapons were still covered by a simple wooden plank, which was easily smashed and burned by the heavy objects and torches of the defenders.

The flame that Yuan Jun was looking forward to was stifled invisibly.

And after the distance is widened, the efficiency of throwing torches is even lower, and it is impossible to throw them on the deck of the Han army's fighting ship, almost 100% can only be thrown on the side wall of the ship.

"Puff puff—"

Liu Ye's output can't even break the shield at all.

After killing a few of the soldiers on the stern of the Yuan army, when the iron cone springboard of the Guan Yu battleship hit the other ships again, the Yuan soldiers on the stern even directly knelt on the ground and surrendered the whole ship, without waiting for the enemy to jump to the gang.

After all, there is nothing more demoralizing than a daring man who risks his life to rush forward, only to be told that his efforts are "smoke-free and not harmful."

Although the initial flame was mainly a fire caused by tung oil, even a simple fireproof plank would ignite as long as it was continuously burned for tens of seconds at most.

"I thought Liu Xun was a scheming person, and he was able to come up with so many new and small tricks for fire attack, I guess I heard some kind of strategist, right? Could it be Liu Ye? ”

However, this is not the most terrifying and desperate point for Yuan Jun.

Zhuge Jin was overjoyed, commanded all the armies to cover the killing, and killed and wounded thousands of prisoners, only then was the remaining enemy took advantage of the chaos to open the distance and escape.

……

Zhuge Jin had long thought that if he wanted to attack fire, he must take into account how to extinguish oily flames. Then I thought of using wet mud - this is also the easiest way for the ancients to achieve it from local materials.

Not to mention, Liu Ye's urgency is actually similar to the "swallowtail torch" that appeared in the Northern and Southern Dynasties in later generations, which is very in line with scientific principles.

On the largest fighting ship, watching the flames that had just ignited on his own battleship being quickly extinguished, Guan Yu, who was originally nervous, was also calm again, and his mood was uplifted.

That is, there is no special fire extinguishing and emergency repair training, and there are no special personnel and special tools to be responsible, which is too simple. Since I have started to build a naval army, I must start to rectify it from this point first.

Guan Yu's morale was greatly boosted, and he continued to chase the enemy's squadrons and fleets that were still fighting with Gan Ning and Tai Shici, and attacked them front and rear.

It was Guan Yu's turn to use this kind of iron cone that Yuan Jun had never seen before, and slammed and fixed those fly-like walkers.

Of course, in ancient China, there were similar gangplanks with pointed iron cones on the head, and even Gan Ning used similar things. But usually these pieces of equipment were either hand-held and lightweight, or they were only one in front of the bow.

Liu Xunjun's fire attack was declared a complete failure.

The cone springboard of the Raven Battleship is also useful against the enemy's large ships.

Many of the small boats of Yuan's army were attacked from near and far in vain, paying huge casualties, but they could do nothing, and the fierce battle lasted for about half an hour, and finally the morale completely collapsed.

After paying so much price and suffering so many beatings in vain, Yuan Jun's arson team finally killed in front of Guan Yu's five large fighting ships!

But Liu Xun and Qiao Rui also knew that this was not the pot of Liu Ye's tactics, but that the troops were out of shape at the execution level.

However, the ideal is very plump, and the reality is very skinny.

Zhuge Jin threw the torch to the ground: "This kind of thing is originally prepared, who let the Han army's navy have almost no damage before-I mean damage control."

He also freed up all his massive army troops, and concentrated on breaking through the outer blockade of the Han army and approaching Guan Yu's Chinese army.

To put it bluntly, it is a bit like the Romans' crow warships jumping to set up a board, relying on gravity to directly release it and tie it into the boat, and then lock the other party, jump to the gang to catch the gang and slash and kill.

The Yuan army's death squad suddenly lost its morale and fell into chaos, and was killed and injured by the Han army's bow and crossbow.

If you feel that gravity alone is not hard enough, you can continue to pull the noose on the coaxial wooden gear of the rotating shaft to accelerate during the falling stage, so that the inertia of the smashing is more fierce.

A torch with such a weight, when thrown, will spin like a grenade in later generations. With the blessing of inertial centrifugal force, if it hits the side wall of the plank, there is also a considerable probability that the hook will be nailed, so that the torch can be hung upside down on the board and continue to burn, greatly improving the efficiency of arson.

But when he thought of Mr. Ziyu's practice of his basic skills in the past few days, his heart rose with confidence.

When used, the sailor first lifts the end of the iron cone springboard, and then pushes it along the board to the middle, and when it cannot be pushed because of the strenuous lever, it then relies on the noose to pull the rudder wheel-like wooden gear on the hinged shaft to complete the final overhead release.

Moreover, the lever must be fixed vertically, which has too much negative impact on the rise of the center of gravity of the hull, and the navigation stability will drop sharply.

But the amount of work was too large, and he didn't have enough time to build it in Chaisan before the war.

"It can't be! This is a tung oil fire, and it can't be extinguished even if you splash water! The tung oil will float on the water and continue to burn! Could it be that the white pulp is weird? ”

In the initial stage of the Yuan army's hand-to-hand encounter, the battle loss exchange ratio looked quite embarrassing, and Liu Ye's idea seemed to have no effect at all.

Gan Ning and Tai Shici actually played well just now, but they were not as crushing as Guan Yu's side.

As the boat team entered within 100 steps of the fighting fleet, Guan Yu took the lead in giving an order to let the ships shoot freely, and for a while, the river surface was like a rain of arrows, and the protection of the boats was inferior, and it was much shorter than the fighting ships.

"Smack! Syllable! "There were a few loud noises on the ground, and several solid wooden planks about two feet long, several feet wide, and about one foot thick, with iron bars reinforced on the surface, and an iron cone weighing dozens of pounds on the top, suddenly smashed down from the side of the fighting ship.

Seeing that Yuan Jun's team was swarming and killing, Guan Yu was also like a great enemy, with a solemn expression.

The torches fell on the deck with all their might, or they flicked their tails and stuck to the side of the ship after impact, and with the blessing of tung oil, flames immediately burst out from several places on the fighting ship.
