In general, the main threat to the raft is the trebuchet, because the stones thrown by the trebuchet can smash the raft or the boat, and even if the raft is not hit, the resulting waves will cause the raft to shake, making the soldier unstable on the boat.

Although the strength of the crossbow is huge, it is at most only to shoot through the bodies of several Qin soldiers, and the impact on the raft is not great, and the power of the bow and arrow is smaller than usual, because the soldiers are standing on the raft, they don't have to move around by themselves, as long as they erect a good shield, protect themselves, and protect the soldiers who operate the boat. Therefore, as long as they passed the range of the trebuchet and entered the blind corner of the trebuchet's range, the damage to the Qin soldiers was reduced a lot.

Although under the blows of the defenders, forty or fifty rafts and boats of the Qin army have capsized and sunk, more than 1,000 soldiers have fallen into the water, and a large number of floating corpses have appeared on the water, there are still many siege rafts and boats that have approached the city wall.

Therefore, Xin Sheng saw it in the rear formation, and he was also slightly relieved, under such a blow from the defenders, he was still able to get close to the city wall, which was also a good result, and after the flooding, the height of the city wall of the girder was only about three zhang, which was only equivalent to a medium-sized city, maybe the Qin army still had a chance.

One by one, the rafts approached the city walls, and the Qin soldiers also bravely launched an attack on the city head from the siege ladder. But when the Qin soldiers began to land in the city, they found that the situation was not right, first, the rafts and ships were floating on the water, and the chassis itself was unstable, which brought great difficulties to the Qin soldiers' siege; Second, after the Qin soldiers climbed the siege ladder, the center of gravity rose, which caused the instability of the raft boat, although it did not cause overturning, but the shaking amplitude increased significantly, not only the soldiers on the raft stood unsteadily, but even the Qin soldiers who climbed the siege ladder could only hold on to the wooden ladder tightly to prevent themselves from falling into the water, and they did not care about launching an attack on the city wall at all.

The defenders on the city wall immediately fired their bows and crossbows, and all kinds of stones and bricks were like raindrops, hitting the Qin army on the raft, and the raft shook, and it was very difficult for the Qin soldiers to even stand firm, let alone counterattack the city, and as a result, the defenders were killed and wounded countless times, and fell into the water like dumplings.

At the same time, the defenders also threw down cans of grease and smashed them into rafts and boats, and then shot them down with rockets, and suddenly a fire burned on the rafts and boats, and the fire spread, and in a blink of an eye, dozens of rafts were ignited, and the Qin soldiers were burned to the sky, and they could only jump into the water regardless of a qiē, regardless of whether they could swim or not, if they were lucky, they could catch a piece of driftwood, and they could also pounce on the water, and if they were unlucky, they could only fill the water and sink to the bottom.

In a short period of time, the area on the edge of the Daliang city wall had become a sea of fire, and the water was full of struggling Qin soldiers and floating corpses, and a large amount of blood flowed out, dyeing the water surface a dull red color.

The Qin army's offensive was completely dismantled in the blink of an eye.

The whole process of the war, Wang Jian saw it very clearly, and at this time he couldn't help shaking his head again and again, of course, the battle has reached this point, and the problems that should be seen have been seen, and if he continues to fight, he can only increase casualties, so he also ordered to withdraw his troops.

After the horn of the troops was blown, the Qin army immediately desperately rowed back and left the battlefield, while the defenders took advantage of the victory to carry out another round of pursuit and attack, and after the defenders were out of the range of the attack, they stopped. A large number of floating corpses and broken masts were still burning on the surface of the water.

The defenders let out a cheer to celebrate the defeat of the Qin army's first attack from the water. Because in this attack, the defenders almost completely suffered no casualties, which was something that had never happened in previous offensive and defensive battles.

Originally, after the Qin army released water to irrigate the city, although the city did not enter the water, it was surrounded by large waters, and the water level rose, which greatly reduced the height of the city walls of Daliang City, which also made many soldiers a little nervous, because it seemed that the advantages of Daliang City were also greatly reduced, but this time the Qin army's attack was repelled by the defenders, which also restored the confidence of the soldiers. It seems that the city of Daliang is still impregnable.

And Gao Yuan ordered to order the raft to go out of the city and salvage the floating corpses in the water, because now the weather is gradually getting hotter, if the corpses are soaked in water for a long time, it is easy to cause the breeding of various diseases, the medical level of this era is very low, and in the almost closed environment of Daliang City, once the disease breaks out, it will be a very terrible thing, and most of the soldiers and civilians in the city will die. When the Qin army released water to irrigate the city, Gao Yuan had already ordered that the military residents in the city should never drink raw water directly, and that boiled water must be used for cooking, washing dishes, and washing clothes, so as to avoid the spread of disease as much as possible.

―――――――― the dividing line ――――――――― dividing line―――――――― at this time Xin Sheng also led the remaining fleet back to the dock of the Qin army, the Qin army lost a total of more than 2,500 people in this battle, and the rafts that were burned and damaged reached more than 180 boats, although the losses of the Qin army were not large, but this was the first time that the Qin army flooded the Liang Dynasty to launch a surface attack on the city of Daliang, and the result was not as good as when there was no flooded Liang before, which also made many soldiers of the Qin army very frustrated.

After Xin Sheng got off the boat, he immediately rushed to Gaogang to see Wang Jian, knelt on the ground, and said: "The last general is incompetent, and the generals are dismantled, please punish the general." ”

Wang Jian waved his hand and said, "General Xin, I can't blame you for this battle, our Qin army was already negligent in water warfare, and we still need to train diligently in the future." But after this battle, what do you think our Qin army needs to train against? ”

Although Xin Sheng did not directly participate in the war, when he returned to the war, Xin Sheng asked some Qin soldiers and generals who participated in the war, so he also had some ideas in Xin Sheng's mind. Listening to Wang Jian's question, Xin Sheng thought for a while before he said: "Back to the general, in the opinion of the last general, there are three main points that our Qin army needs to train, one is the art of sailing boats and rafts, water warfare depends on the actions of boats and rafts, and it is necessary to move forward and left and right on the rafts, and operate them freely, so that there will be no chaotic situation when they leave the dock." Therefore, the first thing our Qin army has to solve is the art of sailing boats and rafts. ”

Wang Jian nodded and said, "Yes, there are more." ”

Xin Sheng said: "There is also the fact that the raft is shaking on the water, and it is difficult for the soldiers to stand firmly, so naturally they will not be able to fight, let alone climb the ladder to attack the city, so the soldiers must be trained to fight on the raft, so that they can walk on the raft as if they were on the ground." In addition, the bed crossbow, trebuchet and other instruments are all started, but the impact on the raft is very great, because it is a trebuchet, once used, the raft will overturn four or five times out of ten, so if you want to use a trebuchet on the raft, you also need a larger raft, maybe several rafts are connected, the situation is better. After a pause, Xin Sheng said again: "Another point is that the soldiers must learn the skills of water, so that even after falling into the water, they will not drown immediately, and can wait for the rescue of other rafts." ”

After listening to Xin Sheng's speech, Wang Jian pondered for a moment and said: "Okay, pass the order, transfer the soldiers who can handle boats and sail from each battalion, gather together, select another 30,000 soldiers, and immediately carry out water combat training, and you will be responsible for all the content of the training. ”

After hearing this, Xin Sheng also hurriedly said: "The last general will respect the order." ”

After Xin Sheng left, Wang Jian looked at Daliang City standing in the water in the distance, and couldn't help but smile bitterly, it seems that in a short period of time, it is basically impossible to attack Daliang City with a raft from the water, although he has ordered to let the soldiers train in water warfare, but Wang Jian knows very well that from now on training, it will take at least three or four months to have an effect, and whether he can break through Daliang City at that time, even Wang Jian has no bottom in his own heart, after all, Wang Jian has never fought a water war, I don't know how far the water war will go. And even if the water is released to flood the beam, if you want to break through the city of the beam, it is destined to be a protracted war.

In addition, Wang Jian has always had a little doubt in his heart that cannot be eliminated, that is, from the release of water to irrigate the city to the present, it has been more than ten days, and except before the release of water, the Fan Yong army broke through the siege of the Qin army, and after breaking through, there was no movement at all, including this time the Qin army found an attack on Daliang City, and the defenders did not make any basic moves except for stationing on the city wall.

This is obviously not in line with the way of using troops on the plateau, because judging from the previous situation, the plateau had long expected that the Qin army would release water to flood Daliang City, and the plateau also did a lot of preparatory work in the city, such as strengthening the city wall, guarding the city gate, etc., of course, these are preparatory preparations, but the plateau must not be a little prepared in the military, after all, now that Daliang City has been besieged by the water, the plateau will not be willing to be trapped in Daliang City.

Although Wang Jian also knows that the grain and grass reserves in Daliang City are very rich, which can support at least one or two years, but no matter how much the material reserves are, there will always be a day when they run out, with the strong national strength of Qin, it is completely possible to ensure that the siege of Daliang for three or four years is completely possible, although the cavalry of the Dai army continues to attack the transport team of the Qin army, but the two sides fight for consumption, and the defenders may not be able to fight the Qin army. Of course, during the time that Daliang City was held, there may be other changes, other countries may attack Qin, and the Qin army will be forced to retreat, so that the siege of Daliang City will naturally be lifted.

However, this possibility is not high, among the existing countries, Yan can be ignored, although the combat effectiveness of the Dai army is strong, but the national strength is too weak, it cannot support an offensive war at all, not to mention that the plateau is not in Dai County now. Therefore, the only ones capable of attacking the Qin army were Qi and Chu, but both of these countries were more than enough to defend the city and not aggressive enough. If they are attacked by other countries, they may be able to resist, but let them take the initiative to attack Qin, and the monarchs and ministers of the two countries may not have this kind of courage. So what does the plateau rely on?
