At this time, more than ten days have passed since the plateau was stationed in Daliang, and during this time, there was basically no battle between the two sides, but they were making preparations for each other. The soldiers and civilians in Daliang City sent tens of thousands of people out to cut wood and dig soil every day, and the Qin army was also building a large number of buildings, building fortresses and camps, each doing its own thing, even if the people of Daliang advanced to the Qin army's position to cut trees, there was no fight between the two sides, and a subtle level of constancy was maintained.

At this time, the trees were basically cut down in the area within 1,000 steps outside Daliang City, and tens of thousands of mud and sand bags were excavated and piled up in Daliang City. Outside the city of Daliang, the Qin army has also established more than a dozen fortresses, and there are countless soldiers, and the people are digging and carrying burdens, and they are busy nervously.

The fortresses of the Qin army are all built in the way that the fortress was built when the army guarded Xingkou, and it is composed of mud and sand bags and logs, but the scale is much larger than the fortress built by the original army, the length and width are about 15 zhang, and it is divided into two layers, the space height of each layer is about one zhang and two feet, and at the top of the fortress, there is also a mud and sand bag wall that is more than half a zhang high.

At the four corners of the castle, a wooden arrow tower more than four feet high was also built, and each arrow tower could accommodate twenty archers. At a distance of about thirty paces around the perimeter of the fortress, a trench was dug around the fortress, one zhang deep and two zhang wide, and an earthen wall composed of mud and sand bags half a zhang high was erected at the edge of the trench. And arranged six bed crossbows and stone trebuchets. And at the rear of the fortress, there was also a camp.

In the past, it took about ten to fifteen days to build a fortress of this size, but because it was a mixed structure of mud and sand bags and logs, the construction speed was very fast, and it only took four or five days to build, plus the time to dig trenches, about ten days, the entire work of a fortress could be basically completed.

Gao Yuan estimated that a fortress like this could hold at least fifteen hundred soldiers and necessary supplies, and with the soldiers of the outskirts and camps, there were about 5,000 people in total.

Moreover, during this time, the Qin army also transferred a large number of civilian servants, so several fortresses could be built at the same time, and there were five such fortress systems on each side of the city wall, at this time the Qin army had built ten such fortresses on the north and south sides of Daliang City, and the distance from Daliang City was about 1,000 to 800 steps. In front of each fort, an earthen wall was being built, about two feet high, and on the east and west sides, work began on the fort, which, once completed, would be enough to completely enclose the girders.

The plateau led the generals to stand on the tower and look out, on the north and south sides, the blockade of the girder was basically a system.

Zhao Jiang said: "Qin Jun is learning so fast, we did this in Xingkou at the beginning, and now we are completely imitated by Qin Jun, and they are completely in our style." ”

Ling Feng said: "However, the Qin army's fortress is much larger than the one we built in Xingkou, and it can almost catch up with a small city." ”

E Chongyu did not participate in the Battle of Xingkou, but he was a person who had gone through the Battle of Jingcheng, and he had a very clear understanding of the strong strength of the Qin army, and said: "You look at how much manpower and material resources the Qin army has invested, I think that the civilian service they recruited is not below 300,000 people, plus a part of the army, I am afraid that only the Qin army can achieve a complete blockade and encirclement of Daliang." ”

Ling Feng pointed to the earthen wall being built between the two forts in the distance and said, "If you just want to block the girders, you only need to build a few more forts, and wouldn't it be a little redundant to build one more earthen wall?" And it also costs a lot of manpower and material resources. ”

Zhao Jiang said: "Maybe the Qin army wants to completely surround Daliang City, relying on the fortress alone, although Daliang can be blocked, but it can't be completely surrounded, maybe it's afraid that our cavalry will break through, anyway, there are many people in the Qin State, so let's waste a little manpower." ”

Ling Feng shook his head and said: "If you only want to surround Daliang City, you only need to dig trenches, it is more labor-saving to build an earthen wall, and if it is a earthen wall, it should also be built by attaching to the fortress, but the earthen wall built by the Qin army is obviously in front of the fortress, and the distance is almost more than fifty steps, but there is only a gap in front of the fortress, which is very unreasonable." ”

Gao Yuan said: "The role of this earthen wall should not be used for fortifications, but for the construction of a cofferdam for the future release of water to irrigate the city, because the slope of the earthen wall is very large, you can climb up directly without any gongbei, if it is used for fortifications, this style will never be built, only the river dam is this structure, and according to the scout's report, now the Qin army is building the embankment of the chasm, and is also building a river channel to divert water, which shows that the Qin army's plan to irrigate the beams with water, It has already entered the actual implementation stage. ”

Although the plateau has always emphasized that the Qin army will use water to irrigate the beam, there are still many people who are skeptical about it, because in this era, there are not many tactics of water attack, and many people do not have much understanding of water attack, and although the terrain of the beam is not high, after all, it is still dozens of miles away from the Yellow River, and the amount of water in the chasm is indeed limited, even if it is released water, it will not be much of a threat to the beam.

But judging from the current frame of the Qin army, it is indeed a case of releasing water to irrigate the city, so it also makes many people a little nervous.

Jiang Huanwu said: "Lord, we must not let the Qin army build a cofferdam and fortress so calmly, and complete the encirclement of the Great Liang, we should immediately send troops to attack and break one or two fortresses of the Qin army." to shock the Qin army. ”

Lu Renjie said: "Now there are nearly 300,000 Qin troops outside the city, and there are 300,000 or 400,000 civilian servants, and there are only 50,000 soldiers in our Daliang City, and the disparity in strength is too great, and the attacking side is always more difficult than the defending side, so it may not be able to capture a fortress if you venture out of the city to attack the Qin army, and even if you capture a fortress, what is the use, we can't send troops to garrison it, once we retreat to Daliang, the Qin army will soon be repaired." On the contrary, if other Qin troops are allowed to come to the rescue and cut off our retreat, then our army will probably be in danger of being wiped out, which will be a great blow to our morale. ”

Jiang Huanwu shook his head and said: "Although the strength of the Qin army is far superior to ours, but now they are besieging and scattering their troops, but we can concentrate our forces and attack the Qin army a little, and even send out two armies to feint, so that the Qin army can take care of one and lose the other, so our chances of victory are still very large, although we can not garrison the fortress, but we can mess up the formation and exhaust the troops, so that the Qin army has to repeat the construction and work repeatedly, and once we win, it can also boost the morale of our army." ”

Gao Yuan nodded and said: "I also agree with General Jiang's opinion, the weakness of defending the city is that the troops are scattered, and they must be overwhelmed, in fact, the side besieging the city is the same, so the side defending the city must take the initiative to attack and seize the initiative in their own hands." We must not only take the initiative to attack, but also continue to attack from all gates in the future, or several armies at the same time, so that the Qin army will be difficult to take care of and exhausted. As for our lack of troops, don't we still have more than 40,000 reserve troops in the city? We can let them fight appropriately, not only to make up for our lack of troops, but also to allow the reserve army to gain combat experience and be able to take on heavy responsibilities in future battles. ”

Zhao Jiang said: "The lord's words are very strong, we should go out to attack." ”

E Chongyu also said: "Yes, now that the trees outside the city have been cut down, and the training of soldiers has been going on for a long time, we don't have much to do next, if we don't move, I'm afraid that the morale will slowly wear off." ”

Gao Yuan said: "Okay, then don't hesitate, notify the defenders of each city, gather the army, and we will attack immediately." ”

Because at this time, it was the first time in Daliang City to fight, and Gao Yuan did not dare to be careless, mobilized elite soldiers and strong generals, and made full preparations.

The purpose of this sortie was to attack the position of the Qin army, so the strength of the sortie was mainly infantry, and the main force was divided into three teams of 3,000 people, each team was divided into 1,000 spear and shield soldiers, sword and shield soldiers or sword and shield soldiers, 1,000 crossbow soldiers, and 1,000 cavalry troops. He also brought twelve bed crossbows, twelve trebuchets and a hundred long ladders for long-range attacks on the Qin fortress, and three thousand reserves, each with a hundred shovels and picks, and prepared to fill the trenches, and the material for filling the trenches was the mud and sand bags used for the earth walls.

At the same time, the plateau also assigned three armies, each with 5,000 troops, all of which were composed of the Wei army, which attacked from the other three sides as a feint to contain the strength of the Qin army. And Jiang Huanwu led the remaining Fan Yong army to stay in the city as a receiving force.

The total number of troops in this battle reached nearly 30,000, accounting for one-third of the defenders in the city, and the fact that the plateau personally led the army to the battle also shows that the plateau is determined to win this battle. The morale of the Wei army was also very high, because the plateau had become a symbol of invincibility in their hearts, so everyone was full of confidence in this battle.

The city gate was opened, and three thousand men were the first to come out of the city, all of them were in the front according to the spear and shield soldiers, the sword and shield soldiers were guarding the left and right, and the crossbowmen were in the formation of a zigzag, and then the thousand cavalry army was divided into two groups, which were on the left and right, and twelve bed crossbows and twelve trebuchets were also pushed out of the girder, and together with the three thousand reserve troops, followed behind the three thousand troops.

After the battle, the Dai Wei coalition army quickly arranged the formation and approached a fortress on the right in front of the city gate.

The Qin army also quickly made arrangements, and one by one the Qin troops fought out of the camp in the fortress or in the rear, formed a formation in front of the fortress, and prepared to engage the Dai Wei coalition army.

Because the earthen wall of the cofferdam built by the Qin army left a gap of about 20 zhang wide in the direction of the fortress, so the formation of the Qin army was concentrated behind the gap, and the front formation was spread horizontally, all the way to the front of the earthen wall, leaning against the earthen wall, and on the left and right earthen walls, several rows of crossbowmen were also arranged. In this way, not only can you lean on your back, you don't have to worry about the coalition forces attacking from both sides, but you can also get the cover of the fortress and arrow tower behind you.
