'Boom, boom, boom......'

"Those guys on the rocket ship have eyes on the back of their heads, how are they bombarding us!" Du Meng on the Yongmeng scolded. Now he is the commander of the dragon boat detachment, and he was ordered to command the assault detachment in this battle.

According to the tactical arrangement, the rear team of the returning army was attacked, and after entering the range of the rockets, it immediately ordered the rocket ships to concentrate fire and launch, in order to isolate the enemy's rear army and the Chinese army, and delay their movements, so that the dragon ships could launch a collision. After they entered the attack position, they had already launched an attack, and according to the regulations, in order to avoid accidental injury, the rocket ship should stop firing or divert the fire, but seeing that there were still explosions around the dragon ship, although it was not hit, the ship was rushed and swayed sharply from side to side.

"Command, it's not the rocket ship that fires, but the ......" After giving the order to stop firing the rocket ship, Guantong responded that he had already stopped firing, and after he re-observed, he had not yet finished reporting, and suddenly fell from the watchtower.

"What's going on?" Du Meng, who was on the command platform, immediately looked back and asked.

"Commander, Guantong was hit in the head and has been killed!" The ship's healer immediately stepped forward to inspect it and replied gloomily.

"No, the slingshot doesn't have such a great power, it should be a firearm!" Du Meng stepped forward to inspect it. He knew that some Meng Yuan archers were good at using bows and crossbows to shoot iron pills to kill people, but it was impossible to almost smash people's heads at a distance of thirty years, and then he immediately thought of firearms, not to mention smashing the head, even if it was possible.

'Knock, knock, knock......' A series of critical hits rang out from the ship's hull as he spoke.

"Report to the command, the enemy is shooting at us with a short gun, and the enemy trebuchet is not throwing stone bullets, but iron bullets filled with gunpowder!" Another Guantong hand was upgraded again and inspected, and hurriedly returned to the report.

"Your Majesty's worries have really arisen." Du Meng gritted his teeth and said, "Order the dragon boat detachment to fire freely with ballistas, alternately cover and withdraw from the battlefield in columns, and at the same time report to the commander that the enemy army has been equipped with firearms, and ask for instructions on how to act next!" ”

"Obey!" Guan Tongshou risked his life and went out of the cabin to report to the Chinese army in the language of the flag. At the same time, the ships fired at the enemy ships with ballistas, suppressed the enemy troops, quickly retreated, regrouped at a distance of 200 paces from the enemy position, and fired at the enemy with heavy ballistas.

"The commander ordered our ship to quickly find out the type and range of the enemy's firearms, and told us to be cautious and not to make any mistakes!" Guan Tong replied with his hand.

"Rule, why be so cautious?" At this time, boatswain Cao Denglin walked up to the command cabin and asked puzzledly. The dragon boat has always been the vanguard, only advancing and not retreating, but today it was only a slight blow, and the whole army retreated, which was something that had never happened, and it was also inconsistent with their tradition of never giving up.

"What do you know, this is a strict order from His Majesty, and the use of firearms by the enemy must be treated with caution. Obey orders, violators will be severely punished! "Since the formation of the dragon fleet, there have been few casualties, and not long after the battle started today, someone was killed, Du Meng said angrily. Then he called the lookout and personally upgraded the cabin to observe the enemy situation.

"What's wrong with the rule today, such a big anger!" Cao Denglin was scolded for a bloody squirt, but he didn't know why, so he couldn't help complaining.

"Say no more. What the Commander said is right, this is exactly what His Majesty ordered ten years ago. Pan Yunqi, the gunner, pulled it aside and said softly, "At that time, you had not yet joined the army, and I was just a gunner on the Warrior. His Majesty sent troops to attack the enemy's position at night and captured two bronze cannons, although the cannon was rudimentary, but it was not enough for gunpowder, otherwise the power would be extraordinary. ”

"Your Majesty therefore ordered that when encountering enemy troops armed with firearms, you must be careful not to underestimate the enemy, so as not to cause unnecessary casualties. The dragon ships built later were not only thickened with gunwales, but also paved with iron plates, and the bottom of the ship was also wrapped in copper to enhance protection, but this was the first time since then that an enemy army equipped with firearms had been encountered. ”

"Do you want to give up and run away?" Cao Denglin frowned.

"How could it be, it's just a temporary withdrawal from the battle at the moment, and the attack will start again when the situation is clarified!" Pan Yunqi smiled.

"Why are you still chatting here, you will be in place right away!" Du Meng saw that he was still talking here, and said angrily.

"Yes!" When the two heard this, they hurriedly took up their posts.

"Tell the commander that the enemy warship throws explosive bombs with a catapult, in the form of direct ignition, with a range of about 100 paces and medium power. In addition, the enemy's armament is shaped like a musket, about two feet long, according to the size of the projectile, the caliber can be judged to be about seven points, it can be fired by a single soldier, there is no aiming device, the effective range is about 50 steps, the power is powerful, and it can cause death! Du Meng said as he ordered Guantong to report to Zhang Hao.

"The commander ordered my detachment to use ballistas to kill and damage enemy ships on the side of the ship, and to be cautious in the tactics of ramming the enemy in close quarters, and to keep a distance between the ships and large ships equipped with catapults. Adopt the tactics of scattered assault to cut off the connection between the rear army and the Chinese army! Guantongshou quickly replied to the report.

"Order all ships, in groups of two, to fight in tandem, disperse the assault, and be sure to divide and destroy the enemy!" Du Meng immediately conveyed the order to the ships, and at the same time ordered the rocket ships attached to the operation to open fire first, preventing the large warships sent by the Chinese army from joining the rear army.

The 'skinning' tactic was already a common tactic used by dragon ships, and at this moment they were cruising in pairs, cruising outside the range of the firearms of the Mengyuan warships, the front ships took advantage of the fast rate of fire of the ballistas to sweep away the soldiers on the side of the enemy ships, and the rear ships fired solid bullets with heavy ballistas to hit the parts of the enemy ships below the waterline. The proper tactics quickly achieved results, and for a time the army behind the enemy was turned upside down, and the warships waiting for the enemy's reinforcements rushed to this sea area, expelled the dragon boats, and there were only a few warships floating on the sea, either capsized or sunk to the bottom, and could only be busy salvaging the sailors who had fallen into the water.

And the dragon fleet was like a ghost that lingered, and soon went back and forth. After the battle just now, Du Meng has discovered the weakness of the enemy's explosive bombs with a catapult, although their principle is the same as that of a ballista, but the difference in the way of use also determines that the inherent slow firing speed of the catapult and the low hit rate are difficult to overcome.

And Du Meng found that the bursting bombs used by the Mengyuan Navy also had problems. The charging method used was also to fill the gunpowder in the cast iron shell, but in the ignition method, they could not solve the problem of the fuse, and still used the old method of burning with a red-hot iron cone to ignite the gunpowder. And this creates uncontrollability, if the hand is slow, it will explode in its own hand, and if the hand is fast, it will fall into the sea and be annihilated before the gunpowder is ignited.

Du Meng suspected that this was when Meng Yuan was secretly learning, but he didn't know one or the other, so he couldn't build a ballista and had to use a stone thrower, and this ignition method was okay on land, at least it would not be extinguished if it fell on the ground, and it could still explode, but it wouldn't work at sea. If the ship is blown up, the ship will be destroyed, so the gunner can't help but tremble, and whether it ignites or not, he will immediately fire the shell. At the same time, the uncontrollable timing of the explosion often creates uncertainty, and no one knows whether the shell will go off or where it will land, but it is scary enough.

In response to this situation, Du Meng commanded the dragon ship to fire chain bullets in motion, first tearing the sails of the enemy ship to pieces and making it lose power, and then summoned the rocket ship to fire at it. Although rockets are not very reliable, they have a long range and a large coverage area, and they are still a great threat to fixed targets......

Dong Yicheng saw that the Imperial Front Navy was dragging back the Hui Navy Army and blocking the retreat of the Goryeo Navy Army, so he waved his army forward and began to further compress the formation. Seeing that there was no way to retreat, the Goryeo naval army could only fight, but their strength was even weaker. You must know that after Goryeo was conquered by the Mongol Yuan, not only did it have to pay huge taxes every year, but also accepted the conscription to send troops to fight for the Mongol Yuan. Although Goryeo was in pain, Kublai Khan still squeezed out nearly 25,000 soldiers and sailors, as well as 900 warships and 100,000 stone of grain from Goryeo.

Subsequently, the Mengyuan expedition to Annam and Champa required Goryeo to contribute money and efforts to build warships, and the continuous exploitation of the years has made its financial resources unable to make ends meet, and the endless conquest and recruitment of young and strong people have made the people tired, and it is difficult to recuperate, and the national strength has declined to the extreme. This time, the requisitioning of the Goryeo Navy could only be pieced together, and he couldn't take care of the quality, so he could barely cope with the errand. I didn't even have enough grain and grass to get on the way, so I had to go all the way and grab it all the way.

The navy is inseparable from warships, but you must also know that the navy has always been a big money-burner since ancient times, and Zhu Di of the Ming Dynasty went to the West seven times to show the national prestige and created a powerful fleet. But as soon as his son succeeded to the throne, he not only disbanded the fleet, but also burned the drawings and models of shipbuilding, because the national strength was no longer able to support continued shipbuilding, and even the thoughts of future generations were destroyed.

In the eighteenth and nineteenth centuries, Great Britain was known as the country on which the sun never set, and it could be regarded as the world's largest power at that time, but it was also careful about shipbuilding. At that time, the price of a first-class battleship was a million pounds, and the British royal family spent less than 40,000 pounds to buy Buckingham Palace, which is equivalent to saying that a first-class battleship is equal to thirty Buckingham Palace.

Judging from the size, a first-class battleship of two or three thousand tons is far less bright than Buckingham Palace, which has a construction area of 180,000 square meters and a garden area of 1,500 acres. From the decoration point of view, the second-hand Buckingham Palace only cost more than 70,000 pounds to become a world-famous palace, and the living conditions of the first-class battleships can only be described as shabby.

However, at the outbreak of the American Revolutionary War, the annual income of the British government was 14 million pounds, and only 14 first-class battleships could be built. By the time the steam battleships began to appear, the British government's entire revenue was 70 million pounds, and it was still necessary to build sail battleships. So where did all the money go for the battleships of the first rank?

The first is to buy wood, before the rise of ironclads, battleships were giants that devoured top-quality wood. In the case of Nelson's Victory, the keel is made of teak, and the rest of the body is made entirely of oak. The thickness of the ribs of the entire "Victory" exceeded half a meter, and a total of more than 2,500 hundred-year-old giant trees were consumed, and 240,000 square meters of forest area needed to be cut down. When Du Mu described the grand scale of Afang Palace, he wrote, "Six kings are over, and the four seas are one." Shushan Wu, Afang out", which is used in the British Navy is "the forest is bald, and the fleet is out".

During the Napoleonic Wars, Britain lost timber imports from the European continent and had to use indigenous timber, with the result that almost the entire country of oak was cut down, not sparing even small saplings. Fortunately, after the Battle of Trafalgar, the British Navy won maritime supremacy, and in order to maintain the size of their fleet, they planted trees all over the world, covered all the forests in Northern Europe and other places, and also carried out oak planting in Canada for decades, which alleviated the problem of timber shortage.

At this time, artillery was still popular, even if it was not counted for the time being, a warship was worth a lot, so that Zhao Yu did not dare to update the warship on a large scale for many years, and most of them could only be transformed and replaced with captured ships, even if this was a large expense. And Goryeo can only be regarded as a country of projectiles, with limited national strength, and more than 2,000 warships have been built in more than ten years, which is beyond what they can bear.

Therefore, if you don't think about it, the king of Goryeo has to take his pants and ask for food. Then the quality of these warships can be imagined, they requisitioned all the domestic ships, whether they were sea ships or river ships, and repaired them to fill the number, fooling the Mongols. Therefore, it is not only the cowardice of the Goryeo naval army, but they really have no confidence in their own warships.

Goryeo is so poor that they naturally have no money to equip them with such 'high-precision' weapons as trebuchets, giant crossbows, and slapping rods, and they dare not collide with the hostile, and the tactics that can be used are the most primitive hand-to-hand combat, of course, they still have an absolute advantage in numbers, as long as they get on the opponent's ship, it will be half of the victory. However, they didn't know that the Song army had already eliminated this tactic, playing without contact combat, but relying on long-range firepower to eliminate the opponent.

The last struggle of the trapped Goryeo navy was like a moth to a flame, and the flesh and blood were blown sideways by rounds of rockets, and the mast fell and broke. When they rushed through the blockade of rockets, they were covered by heavy artillery fire, and it was difficult for them to advance an inch. A desperate attack caused the Goryeo navy to lose thirty percent of their ships, and this huge loss was unbearable, and completely knocked out the last vestiges of their remaining confidence, and retreated like a tide, and under the further pressure of the Song army, the Hui navy was surrounded in a narrow body of water......
