After returning to the water village, the warships and sailors were warmly cheered by the soldiers stationed on the city walls to celebrate their victory.

Because this was also the first time that the defenders of Daliang took the initiative to attack the Qin army after the Fan Yong army broke out of the encirclement of the Qin army, and won the victory. Since it was after the Qin army released water to flood the outside of Daliang City, this was the victory of the defenders of Daliang who took the initiative to attack, and it was no longer just a defensive victory, and the uplifting effect on the morale of the soldiers and civilians in the city was naturally self-evident.

After the return of the navy, after the inventory, 12 ships of this war army were damaged and 9 were damaged; Fifty-three rafts were damaged, 872 soldiers were killed and 623 wounded. In addition, 237 Qin soldiers were captured, four battle ships, twelve rafts, three bed crossbows, and one trebuchet.

Although the defenders did not know the casualties of the Qin army, anyone who had seen the battlefield could see that the losses of the Qin army far exceeded that of the Dai army, so it could also be said to be a great victory.

At this time, the Qin army had besieged Daliang for more than three months, and it had been nearly a month since the release of water to irrigate the city, although there was no shortage of grain and grass materials in Daliang City, and the attack of the Qin army did not cause much danger to Daliang City, and there was no threat of breaking the city, but it still brought a lot of pressure to the soldiers and civilians in the city.

Although the plateau issued a strict order that drinking water and bathing water must be boiled water, not everyone can strictly enforce it, and it is better in the army, and there are still many people in the civilian population who do not boil water for convenience, and there are more than 1,000 sick soldiers and civilians at this time. Fortunately, it was the plateau that adopted the forced isolation measures and brought the sick people together for treatment, which controlled the spread of the disease. At the same time, the plateau once again issued a strict order that water must be boiled for drinking. However, the increase in the number of sick people has also had a great impact on the soldiers and civilians in the city, so now in Daliang City, a hearty victory is indeed needed to boost the spirits.

This time the great victory of the naval army was indeed timely for Daliang City, so Gao Yuan also ordered that cattle and sheep be slaughtered, celebrated in the city, and a certain amount of meat and wine was distributed to each household. In fact, it was hoped that the victory in this battle would boost the soldiers of the whole city.

And the city of Daliang celebrated again, but the camp of the Qin army was gloomy.

In fact, in this battle, the loss of the Qin army was actually far greater than the expectation of the Dai army, this time, the Qin army dispatched nearly a thousand rafts, nearly 20,000 soldiers, and finally escaped back to the Qin army The number of rafts was only more than 100, and the number of dead soldiers also reached more than 12,000 people.

And after this battle, the generals of the Qin army did not doubt that the Qin army was indeed not the opponent of the defenders in terms of water warfare ability, so after the defeat returned to the camp, Xin Sheng and Yang Duanhe pleaded guilty to Wang Jian, although they were pardoned by Wang Jian, the defeat of this battle was not the fault of the two, and the generals had no objections, after all, everyone knew that whoever had changed the command of this battle was not better there.

However, Xin Sheng and Yang Duanhe can be exonerated from the crime, but what to do about the next battle, everyone feels helpless.

At this time, Wang Jian said: "Generals, although our naval army is not as good as the Dai army, but Daliang City is still under our siege, this is an unchangeable fact, so we do not engage in war with the defenders, as long as the defenders are trapped in Daliang City, the defenders' food and grass are exhausted, or the water will rush across the wall of Daliang, then Daliang City can be self-defeating." ”

When the generals heard this, they all nodded yes, because there was no way to fight a water war, so they could only consume it with Daliang, until the food in Daliang City ran out, or the city wall was soaked by the water for a long time, collapsed or seeped water, causing the city to be flooded by water, and the Qin army would be able to break through Daliang City.

Of course, in this way, this battle will be protracted, maybe it will surpass the Battle of Changping, and the water transportation of grain and grass materials is even more important, so the river must not be cut off.

At this time, Li Xin said: "General, the only way to order, it is indeed as the general said, can only do a long-term siege, but according to the last general's view, the army will never sit still in the city of Liang, after this victory, will definitely take the initiative to attack, and strive to break our siege, and in these water battles, the use of trebuchets to project stones or oil canisters to attack the ships of the army is very effective, and the crossbow to the ships is limited, but now our army's trebuchets have lost more than 240 planes, and there are only more than 400 left, trying to hold the cofferdam, It would take at least 800 trebuchets to trap the defenders, so it would take a lot of effort to make them. ”

Because judging from the results of this battle, among the several water warfare methods summarized by the Qin military to deal with the Dai army, the idea of using trebuchets to project stones or oil tanks to attack warships is basically feasible; But putting the trebuchet on a raft and holding it in the water is obviously a hard way to use the tactics on land in the water. Because in land operations, trebuchets and bed crossbows are generally placed at the forefront of the array, and they first launch long-range strikes against the enemy, and once the enemy crosses the strike range of long-range weapons, other armies from the ground will step forward to fight the enemy over the trebuchet and bed crossbows.

This set of tactics is certainly effective on land, but it is not the same at all in the water, because the operation of the raft is far less flexible than the movement of the soldiers, and placing the raft with trebuchets and bed crossbows at the forefront of the array will block the movement of the rafts behind; Second, a large part of water warfare is long-distance combat, and the distance advantage of long-range weapons is not as great as that on land, such as the attack distance of the large warships of the Dai Army, which is not under the trebuchet, so that the raft fixed in the water with trebuchets and bed crossbows will not only be difficult to give full play to its advantages on land in water warfare, but will also become the target of the opponent and hinder its own attack. Therefore, either put the trebuchet on the warship to improve the maneuverability of the trebuchet, or put the trebuchet on the shore to use.

But trebuchets obviously can't be on board, and now the goal of the Qin army is only to besiege the girder, so it is only necessary to put the trebuchet on the shore to use, but in this way, a large number of trebuchets are needed, because the distance that the Qin army has to guard is too long.

After seeing the results of this battle, Wang Jian of course also understood this, so he said: "Okay, the old man will order the craftsmen to hurry up to make trebuchets. ”

Xin Sheng said: "General, now we still have more than 300 warships, since we will not fight with the defenders in the future, it is useless for so many warships to stay in the dock, it is better to take out some of them and transport grain and grass materials." In this way, most of our grain and grass materials can be transported by water, so the army that protects the grain route can be transferred back to help besiege Daliang. ”

Wang Jian also nodded, if you want to besiege Daliang for a long time, you will naturally need a large number of troops, and now the Qin army besieging Daliang has reached 2.67 million, but it is still slightly insufficient, so it is of course good to transfer more troops to join the army besieging Daliang. If the water transportation needs to undertake the Qin army's initiative to transport grain and grass materials, then there is indeed no need for a large number of troops to guard the transportation line.

So Wang Jian ordered to transfer one hundred and fifty warships from the naval army to join the transportation team, and at the same time ordered Wang Ben, who was stationed in Zhongmu, to return to the Qin army camp, and also transferred another 20,000 troops from the Qin army stationed in Yingchuan County, and also from the Qin army stationed in other places.

In the past, the Qin army drew troops from Handan and Yingchuan County respectively to support the Daliang battlefield, but the Qin army stationed in Handan had to defend against the army of Daijun and could not be reduced, so now the Qin army could only draw troops from Yingchuan County, but after this transfer, the Qin army stationed in the entire Yingchuan County was less than 50,000 people. Moreover, Yingchuan County still has the task of guarding against the Chu army, and to maintain the basic order of Yingchuan County, there are not many troops to be drawn, and 20,000 troops is the limit.

However, after all the troops are concentrated, the total number of troops of the Qin army in front of Daliang City will reach 3440,000, plus there are still 300,000 civilian servants, and there are more than 200,000 civilian servants belonging to the Qin State, and when necessary, they can also assist the Qin army, so it is basically enough to besiege Daliang.

But it will take a few days for the armies of all roads to reach Daliang, and the plateau will certainly not give the Qin army time to fully prepare, and the water army that defeated the Qin army in the last battle, although it did not completely eliminate the water army of the Qin army, but also caused heavy losses to the Qin army, and the defenders basically achieved the advantage on the water, so three days later, the defenders attacked from the city of Daliang again and launched an attack on the Qin army.

This time, the direction of the defenders' attack was east, and the goal of this sortie was not to attack the Qin army's naval army, but to destroy the Qin army's cofferdam.

The cofferdam built by the Qin army is built according to the topography, it is an irregular shape, the cofferdam in the north is the farthest from the city wall, more than a thousand steps, and the water area is wide, so it is the most suitable as a battlefield for water warfare, and the dock of the Qin army is also built in the north; The cofferdam in the east is the closest to the city wall, only more than 700 steps, so it is natural to choose this side for the assault with the goal of destroying the cofferdam.

Moreover, in order to create a surprise effect, the defenders also deliberately chose to attack at night, and dispatched twenty large warships, thirty medium-sized warships, and three hundred rafts to sail out of the water village in the night, quietly bypassing most of the city wall, and launching an attack on the eastern cofferdam of the Qin army.
