The pangolin warship was finally built.

With the help of 10,000 soldiers in Jiangxia and the help of tens of thousands of people, within a month, a brand-new warship was built, which was covered with spikes all over its body, like a pangolin. But more people called it "Turtle Boat", and they got used to it when they screamed, and Duan Dahu called it that.

Whether it's a pangolin or a turtle boat, a good ship is a good ship if you can win the battle.

At that time, Jiangxia had only more than 100 warships, which were nothing more than warships, but there was also a building ship, which was used as the commander's command. All the ships, almost all parked at Xiakou, were under the unified command of Guan Yu.

After dinner that day, Duan Dahu took Zhao Yun and Gong Yiyu to Xiakou to watch the naval drills. The water surface of the Yangtze River is endless, and each of them has set up a water village to moor the warship, but the water army of the 100-mile day drill is clearly seen by the enemy's spies, so they are all night drills. Fortunately, on this day, the moonlight was like a cake, shining on the surface of the water, sparkling, like a silver dragon lurking underwater.

When the boat they drove approached the Xiakou Water Village, they found that there were not many warships on the wharf, only a few of them drifted with the river waves, but there was the sound of light boats breaking the waves and weapons clashing on the river behind the village. Duan Dahu said curiously: "What happened?" The soldier who operated the boat was originally the Jingzhou Navy Army, so he said: "It should be General Guan who is training the Navy Army." Duan Dahu said: "Go around to the back and take a look." ”

The boat went around the back, and I saw that on the vast river, more than 100 warships were crisscrossed and crisscrossed, with a little mast and sail, and the waves were magnificent, like a navy composed of ghosts in the moonlight. Duan Dahu grew up in the mountains when he urinated, he was a landlubber, and he saw the naval drills this time, and he couldn't help but have his eyes lit up, and he couldn't help but be colorful.

In the middle of the river, there is a huge ship moored, the height of the ship is nearly six zhang, the deck is huge, the height of the ship is wide, and the appearance looks like a building, it should be the "building ship". The building ship not only has a majestic appearance, but also a spear on the ship, a tree flag, a strict guard, and a strong attack and defense, just like a water fortress.

Zhao Yun is familiar with the art of war, and once fought against the soldiers and horses of Eastern Wu with Huang Zu, at this time said: "Water battles are mainly based on bow and arrow shooting and ship collisions, and the size of the ship directly determines the number of sailors that a single ship can accommodate and the impact force of the ship, so once the war starts, the building ship is the main force." But it's just that the ship is too high, the center of gravity is unstable, and it is afraid of strong winds and waves. ”

Duan Dahu looked at it with his eyes, and saw that the ship was divided into three layers, with Huo Huo in armor, Guan Yu holding the Qinglong Yanyue Knife, wearing a blue robe, and holding the Lingqi standing on the deck on the top floor to direct the training, and he was at ease. Duan Dahu tapped on the warship several times, jumped more than ten zhang each time, and went to the deck of the ship lightly, and arched his hand: "Second Brother Guan, I'll come to see you." ”

Immediately afterwards, Zhao Yun and Gong Yiyu also came one after another. Guan Yu was overjoyed when he saw it, and laughed loudly: "Brother Duan, Brother Zhao Yun, I haven't seen you for a long time!" Duan Dahu introduced Gong Yu to Guan Yu again, and Guan Yu was also overjoyed when he heard that he was a skilled craftsman and a master disciple of the Mo family.

"General Guan, it's really hard for you to train the navy so late. Duan Dahu said.

"Cao Cao's troops in Wulin, only a hundred miles away from Xiakou, he has millions of soldiers, and he still trains the navy diligently, but he must not be careless. I don't want another defeat of Shinno!" Guan Yu said.

Duan Dahu said with a smile: "Second brother, we must be victorious, why should we be so worried?"

Guan Yu saw that he was full of confidence, and said with a smile: "Come, let me introduce you to the current naval formation." "Guan Yu was born in a military family, and he naturally has a lot of experience in marching and fighting, whether it is a short encounter on land or a direct collision with a naval army, it is easy to come.

Under Guan Yu's detailed introduction, Duan Dahu can be regarded as having a preliminary understanding of the subtleties of water warfare. It turned out that Guan Yu divided the warship into four tactics, each with its own role, and the formation was different.

The first is the ship formation, although there are not many warships, but when encountering enemy ships, it is not without a direct charge. Guan Yu will order the flag to fight, the large and small ships lined up, only to see seven or eight large and small warships as a team, lined up in a zigzag shape, the small boat is outside, the big ship is in the middle, no matter how it is exercised, the distance between the ships is always the same. More than 100 boats are lined up in a straight line to swim in the river, and from a distance, it looks like a flock of female ducks leading their ducklings to play in the water.

The second method of warfare is close-to-ship combat, which is inevitable in encounters. Duan Dahu saw pairs of warships lined up in three rows, and the soldiers on the deck used spears, harpoons, crossbows and other weapons to fight each other across the boat, and then put each other's gangplanks to practice boarding and fighting.

Then Guan Yu waved the flag again, only to see that everyone on the big ship shouted one after another, the bow of the big ship is equipped with a slap rod of more than ten zhang, put a boulder on it, press the wheel down, and you can shoot a boulder by pulling the rope, if the head is good, you can penetrate the enemy ship, and hit the small boat and sink at once. Among them, the building ship they are standing on has the greatest power and the longest range. This is the third method of warfare, the slinging battle.

The fourth method of warfare, the soldiers stand on the ship to shoot arrows at the target in the open field, the naval army first compares the bow and arrow, whoever can shoot accurately on the shaking deck can seize the initiative and get the opportunity to board the enemy ship first, after the bow and arrow are released, the soldiers on the shore collect the arrows, and the soldiers on the ship practice hand-to-hand combat.

Duan Dahu looked frightened, he didn't expect that the knowledge of water warfare was so great, but he really had to study it carefully. He was fascinated, only to hear Guan Yu say: "I know brother, you rarely fight in water, so I'll tell you, he really went to the battlefield one day, and I believe there will be gains." ”

Duan Dahu hugged his fists and thanked: "The tactics of water warfare are no less than land warfare, and I have benefited a lot, thank you for the teachings of the second brother!" Guan Yu said with a smile, "You are the generalissimo, we brothers don't have to be polite." Zhao Yun stood aside, and was secretly surprised to see that Guan Yu, who was usually cold and arrogant, was so enthusiastic about Duan Dahu.

Guan Yu asked Duan Dahu to stand at the bow of the boat, and said with a smile: "What I practiced for you, brother, is just the basic skills in water warfare, and when fighting, you should also pay attention to the depth of the river, the width of the river, the change of wind direction, and the degree of water flow, any point may affect the victory or defeat of the battle." In land warfare, mistakes in troop arrangement can be corrected in time, but in water warfare, as long as one wrong step is made, the soldiers cannot correct it for a while, and it is an immeasurable loss. ”

Duan Dahu saw that it was indeed not as convenient for the ship to turn around on the water as it was on land, and no matter how strong his martial arts were, he couldn't control the battle situation, so he sighed: "It seems that this water battle still needs you to come, second brother, and I can't be the commander of this." ”

"The commander is in charge of the overall strategy, and I can help command the water war, brother, you don't have to worry. Guan Yu said, "But there are indeed a lot of tricks in this, such as the depth of the river determines the size of the warship, the shallow draft of the ferry must not walk a big boat, once it hits the reef and hits the bottom, it will be troublesome, but the depth of the river also changes with the change of seasons, only people who know the local waters can grasp the use." There are also a lot of reeds in the river, and the width of the waterway in the reeds sometimes directly affects the victory or defeat of the battle. ”

Duan Dahu listened carefully when he heard him suddenly talk about the reeds, and Guan Yu naturally answered all questions. Duan Dahu only knew at this time that Zhuge Liang had already given instructions to Guan Yu and asked him to explain the method of water warfare for himself.

I only heard Guan Yu say again: "The wind direction and the current can be mixed up, and it is undoubtedly best to have a smooth wind and water, you can set fire to the ship to attack the enemy's ship formation, and the boat and rocket are also more advantageous." Therefore, when the wind is good, we must fight, and when the wind and water are good, we must not fight. ”

Duan Dahu suddenly remembered something and said, "Since Cao Cao's army is in Wulin, and now it is winter when the northwest wind blows, then, is his soldiers and horses smooth?"
