Seeing that the war on this side had stabilized, they moved to the southwest, but seeing that the other side also opened a stance, the Zhending army found that the West Island Water Village was empty and realized the plan, and the soldiers who did not get off the ship hurriedly turned to the East Island, and those who went to the island also hurriedly re-boarded the ship and retreated to the East Island. The Longwan naval army moved southeast to prepare to meet the enemy, so as not to be blocked by the Song army in the narrow waters between the two lanes, making it difficult to maneuver.

"It's an interesting battle!" Zhao Yu looked at it for a moment, put down the telescope and said meaningfully.

"Your Majesty, is there any mystery in this?" Zheng Yong also picked up the binoculars and looked at the enemy formation, except that the enemy ships did not see any difference, and asked puzzledly.

"Hehe, the three armies have no commanders, and they are fighting separately!" Zhao Hao said with a smile.

"Oh, really?" Zheng Yong felt inexplicable, the little emperor saw the problem at such a glance, and he was still confused, as if he didn't understand what he said.

"Can you see the commander-in-chief of the enemy army?" Zhao Hao saw that he was still confused, so he said again.

"No, not really!" Zheng Yong picked up the binoculars again and scanned them carefully, and there was no flag of the enemy commander on either battlefield, which was really strange.

"It's okay, they each fight their own way, but we can unify the dispatch and defeat each of them!" Zhao Yu touched his chin and smiled.

The flag is the soul of an army, it is not only the symbol of the commander, but also the command of the whole army. Therefore, as long as the handsome is there, the flag cannot be served, and Zhao Yu only saw the general flag on the side of the Haidao Cao soldiers, but did not see the handsome flag, and it is still the case when he turns here. Based on this, he can conclude that the three enemy armies of the Yuan army do not have a unified dispatch and command, and it is not impossible to think about it carefully.

Zhending Wanhu Military Mansion, Longwan Water Army Wanhu Mansion, and Haidao Grain Transport Wanhu Mansion, the three prefectures are tied according to their ranks according to the military system of the Yuan Dynasty, and there is no distinction between upper and lower. The Zhending Wanhu Mansion belongs to the jurisdiction of the Wanhu Mansion in Jiangsu and Zhejiang, and the direct superior is the Privy Council; Although the Longwan Navy Wanhu Mansion is located in Jiangsu and Zhejiang provinces, it does not belong to the Jiangsu and Zhejiang Wanhu Mansion, but directly belongs to the Privy Council; The appointment of the 10,000 households of the sea route grain transport came from the center.

Therefore, they are three military units that are not subordinate to each other, and no one can control the other. If it weren't for the urgency of the war, which threatened their respective interests, I am afraid that it would be impossible to cooperate with each other in combat. However, the twisted melon is not sweet after all, although they are fighting together, they are in harmony with each other, and when they encounter problems, they talk about 'democracy', and everyone discusses and handles it. It doesn't matter if it's on weekdays, but if you talk about democracy in a war, you may delay the warplane, and without absolute authority, it will be difficult for each party to act on orders while safeguarding their own interests.

The current situation is exactly like this, the Haidao Cao soldiers wanted to play tricks to avoid the tough battle, but they didn't expect to be confronted by the Song Shuijun, and they had to go hard-headed when they couldn't avoid it; In terms of self-preservation, Zhang Xingzu showed even more obviously, when he found out about the scheme, he immediately seized Dongdao with the intention of leaving a way for himself to live, which fully showed the distrust between them; The Longwan Navy can be said to be a stunned young man, just thinking about making meritorious contributions, and when he saw the Song army attacking, he was red-eyed, and he didn't wait for all the Zhending troops to move to Dongdao, but everything rushed up, which deepened the distrust between the two sides, but they didn't know it.

"Zheng Yong, that's the car and boat!" Zhao Hao's eyes have been staring at the battlefield, at this time I saw an enemy warship rushing out of the channel between the two islands, they quickly occupied the waters in the southeast of Taihu Lake, and quickly lined up, he saw that there were warships without oars and sails in his forward fleet, which was the main feature of the car and ship, but he was not sure, and turned his face to ask Zheng Yongdao.

"Your Majesty, my subordinates have never seen it!" Listening to the little emperor's question, Zheng Yong also observed it carefully, shook his head and said.

"That's the wheelship, yes, my subordinates saw it in the early years!" At this time, Chen Dun, who was standing on the side, responded.

"Oh, it's the first time I've seen you!" Zhao Yu responded, pondering carefully......

As an ancient Chinese invention of a paddle steamer driven by manpower, Zhao Yu, as a student of ship design in his previous life, would of course have some understanding of this kind of car and ship, which is known as the originator of steamships, and has also seen graphics and imitation models, but it is the first time he has seen the real thing. Before the advent of modern steamboats, the propulsion of human ships mainly relied on wind and manpower, the former using sails and the latter using oars.

The vehicle and boat are improved and designed on the basis of the oar, the oar uses hand power, and the vehicle and ship use foot power, which should be a great progress. It is believed that it appeared as early as the Northern and Southern Dynasties, but there is no basis to prove it. But it is clear that Li Gao in the Tang Dynasty played a role in the development of vehicles and ships, and the vehicles and ships he made were moved rapidly by manpower, but in the Song Dynasty, the vehicles and ships were very prosperous.

Ancient Chinese cars and ships were only used for military purposes, and only in the Southern Song Dynasty, they were used and promoted on a large scale. Vehicles and ships are graded according to the number of runners used, and a group of two runners is called a car, and the vehicles and ships at that time ranged from one car to more than 20 cars or even more than 30 cars. The higher the number of cars, the larger the hull will generally be. Many vehicles and boats are used at the same time, and many new types of boats have been developed in inland lakes that can reach very high speeds completely independent of the wind.

As far as Zhao Yu knows, the length of the large car and ship is twenty or thirty zhang, and the draft is about one zhang, which can accommodate seven or eight hundred people; Medium-sized vehicles and ships generally carry two or three hundred people. There are two cars, four cars, five cars and more than 20 cars. Later, the Southern Song Dynasty gradually developed small vehicles and ships. During the time of Song Xiaozong, Jiankang Mansion manufactured a kind of warship with 12 oars and 400 materials, which is about 22 tons today.

Ezhou also built eight cars and five boats, and because of the heavy delay, it was transformed into seven, six, and five cars, a total of five. Jiangxi Road made 100 horse-building boats, concealed female heads, wheels, oars, so that they can be folded and unloaded, this kind of ships that can be loaded and disassembled at any time are also technically progressive. During the Song Ningzong, there was also a kind of iron-walled ploughshare ship, bearing 400 materials, two cars on both sides and three oars, the hull was nine feet long and two feet, it could carry 70 soldiers, and 20 people were treading and driving.

And the warships of the Song Dynasty have also been used in actual combat many times. The Yang Mo peasant rebel army fought a fierce water battle with the official army at Dongting Lake, and the main warships used were vehicles and boats. Its vehicle and ship adopt the type of building ship, the hull is very large, up to 36 zhang, and can accommodate more than 1,000 soldiers. Twenty-two to twenty-four sets of runners are used, but this kind of large vehicles and boats are suitable for a wide water surface, so they are not widely used, and the main use is still small and medium-sized vehicles and boats with less than eight or nine vehicles.

The power of the Song army's vehicles and ships was in the 31st year of the quarrying battle in Shaoxing, and the Wanyan Liangjin army that swept through Huainan drank the horse river and prepared to cross south, but was blocked by the Song army's vehicles and ships that were "flying fast" and ended in failure. After the war, the government counted 6,000 civilian treadmills. In the battle of Xiangyang, the Song generals Zhang Shun and Zhang Gui drove boats to rescue Xiangyang, and then used ships to go out of the city and fight downstream, but they were all defeated.

"I don't see his car, but I see the boat like a dragon!" This is the biggest feature of the vessel, Zhao Yu has seen the side of the enemy ship, there is indeed a raised frame-like structure, which should be the car guard outside the string, its function is similar to the side skirt of a modern tank, used to protect the exposed paddle wheel blades.

Because whether the vehicle and ship are sailing on the water, during the battle, to prevent the enemy from attacking the paddle wheel blades, or when the ship is docked, it is necessary to protect the paddle blades from the impact of the enemy ship or the river bank of the Shuizhai wharf. The paddle blades above the waterline are hidden in the skirt, and the paddle wheel blades below the waterline are covered by the waves, which are also invisible, giving people the spectacle of seeing the boat and not the sail oars.

The speed of the vehicle and the ship is fast, and the advance and retreat are free, but there are also advantages and disadvantages, with two disadvantages that are difficult to overcome, one is that it cannot sail in shallow water, and the other is that it cannot enter the sea. This is also the reason why Zhao Yu left out the vehicles and ships when he chose the warship. In addition, he had just discovered that the car and ship were not as magical as the legend said, and could complete the U-turn with a very small turning radius, but had to slow down and maneuver in a large arc, and the larger the ship, the more clumsy it became.

"Your Majesty, our dragon ship is dispatched!" Zheng Yong saw that the little emperor was distracted, and reminded quietly.

"Dong Commander wants to fight fast with speed!" Zhao Yu listened and turned his gaze to the battlefield again, looking at the situation and said.

I saw that the forward of the Yuan army was led by two 20 groups of paddle steamer vehicles and ships, more than 10 medium-sized vehicles and ships of 10 groups of paddle wheels as the backbone, and more than 40 vehicles and ships with four groups of eight wheels of 'Flying Tiger Warships' as the main force.

In the face of the rapidly advancing enemy ships, Dong Yicheng was obviously aware of the enemy's intentions, but in the face of the fast enemy ships, it was too late to mobilize gunboats to intercept them. Although the enemy's vehicles and ships also had a deep draft, they were flat-bottomed sand boats, and they had an advantage over themselves, and they sailed close to the shore of the lake, making it difficult for the rocket ships to deploy, and even if they were forced, the enemy ships had already broken into the shooting corner, so he mobilized the fast dragon boats to intercept them, and at the same time the gunboats discharged a column in front of the formation, trying to block the enemy with gunwales.

After many battles and exercises, the Song army's dragon ships have formed a relatively mature tactics, they take advantage of the speed advantage to fight in columns, and then use gunwales to repeatedly attack the enemy's flank until the enemy formation is disrupted, and then take advantage of the chaos to break into the enemy formation and destroy the enemy ships by ramming. Today, however, this tactic ran into trouble, as both ships were so fast that they could be said to have passed each other when they were moving against each other, and the dragon boats had to turn around to the flanks before they had time to make a round. If they go in the opposite direction, they can only go parallel to the adjacent enemy ships, and the enemy ships next to them are unlucky, they are held down and beaten, and they will soon be unable to move.

The loss of the speed advantage was there, and the dragon boat also felt threatened. The enemy's large vehicles and ships are not only equipped with slapping rods, but also large stone throwing machines, while medium warships are equipped with small and medium-sized stone throwing machines to attack the enemy and break the village. It is said that the skin of the dragon ship is thick, and ordinary bows and crossbows cannot penetrate the gunplate and cabin roof, and even if the four or five stone bullets fired by the catapult are directly hit, it is difficult to cause fatal damage, so as long as they are not hit by the boulder on the pole, no one can hurt them.

But today is different, when those Yuan soldiers found that the stones fired by the catapult had no effect on them, and they were killed and injured by the cannonballs fired by the opponent, so they changed their tactics. Speaking of which, the dragon boat is still afraid of one thing - fire, although the roof is covered with raw cowhide for arson, it is okay to deal with small fires, but this time the Yuan army directly threw over the oil can, which was broken at a 'pop', and the oil was everywhere, and it caught a little fire 'bang', and even if you turned into the water, it might not be extinguished.

The dragon boats have always been the main assault force of the Song Water Army, and only the best soldiers can be selected, but today they were deflated as soon as they first fought, and two dragon boats were concentrated by oil tanks and ignited a fire, and they immediately broke away from the array and sailed into the open water according to the order, while the other dragon ships moved outward to get out of the range of the enemy's catapult while adding firing strength.

"Go and pick it up right away, and get the person back for me!" Zhao Yu was shocked when he saw this, and urgently ordered Zheng Yong to send a warship to meet the injured dragon boat.

When he saw that a dragon boat with a roof had been recruited had left the group, they immediately sent sandbags up through the watchtower, covering the flames with wet sand, and finally suppressed the fire. The crew hurriedly threw the flowering shells from the port side into the lake, while trying to extinguish the fire with a soaked blanket, but the fire spread too fast, and the starboard side was soon surrounded by fire.

"Abandon ship, order them to abandon ship!" Zhao Hao saw that the sailors were still trying to row the warship to the shore, and the flames had spread along the gun door to the cabin, and he ordered again.

"Lift anchor, side to the outside, use heavy ballistas, fire solid bullets to stop the enemy ships!" Zhao Yu ordered again, now that the enemy warship broke through the interception of the dragon ship, it approached the line set up by the gunboat, and now it had opened fire with all its strength to block the attack, and with the speed of the car and ship he saw, it was enough to rush through the gunboat to intercept it with a desperate sacrifice, so he ordered the Sheji to join the firing ranks.

"Your Majesty, why don't you shoot with rockets?" Chen Dun asked with some confusion.

"Stupid, don't you see that those vehicles and ships are equipped with fire oil tanks, as long as our rockets hit, they will catch fire, and the fire oil that leaks into the water will turn this area into a sea of fire, and now the enemy is downstream, those enemy ships and currents on fire will ignite all our warships, and we can only isolate them at the moment to avoid burning the company camp." Zhao Yu scolded him.

"Then what to do, if they do not hesitate to destroy themselves and press forward step by step, we will not be able to do anything!" Chen Dun spread his hands and exclaimed.

"What to do? The fleet retreated to Hubei first and evacuated to avoid greater losses! Zhao Yu glared at Chen Dun and said angrily.

"This ...... This also said that they would completely annihilate their families, and they would withdraw first as soon as the fight began! Chen Dun became a punching bag, pouting and teasing

"Don't talk nonsense, inform the Han commander, let it cover alternately with gunboats, pull out the formation, and evacuate in the direction of Hubei!" Zhao Yu was also a little discouraged, but the top priority at the moment was to save himself......
