Although this time the Huns said that they concentrated the remaining riders who were still able to fight and launched a large-scale attack on the Qin army, but for the Huns at this time, the Hun riders who consumed a lot of overall consumption would not be able to exert a high combat effectiveness.

King Zuoxian of the Xiongnu may have seen this, so he planned to concentrate his subordinates who were still able to fight at such a time when it was almost dusk to launch a large-scale offensive against the Qin army.

To be honest, Su Jiao still didn't understand such a situation, because he could also think that the Huns were also at the end of the crossbow at the moment, and they also launched a fierce attack on the Qin army in such a situation, and the Huns' combat strength was still between the two, but there was one thing, Su Jiao knew very well, that is, the Huns' arrow stock would not be too much.

After all, the Hun riders did not have additional personnel to carry arrowheads, nor did they have the habit of temporary supplies on the battlefield.

Like many armies that fought in the past, the Huns were more likely to be able to resupply during the truce or use some recovered arrows to continue the battle.

After all, at such a time, there was still a big gap between the logistics and supply system of the Huns and the Great Qin Empire.

In doing so, the other party is likely to give up the plan to supply the corresponding consumable materials, and use the huge advantage in numbers to defeat them.

Su Jiao knew one thing very well, that is, just with those crossbow chariots and the knight troops of Su Ling and Chen Heng, it was still difficult to resist the offensive of these Huns, and if the other party planned to carry out an impact operation under this situation, Su Jiao did not think that in this regard, the troops of Liaoning County under his command would fall behind.

......

And just by letting the mobile troops under his command fight with the more than 50,000 people on the other side, Su Jiao knew with his knees that the mobile troops under his command really couldn't defeat the other party in this regard, and might even be completely wiped out by the other party.

Therefore, Su Jiao simply sent out a fireworks signal, and asked Su Ling and Chen Heng to lead the army to escort those crossbow chariot troops back to the front of the infantry unit.

And Xu Ting's troops naturally need to be gathered.

Compared with the crossbow chariots and knight troops, the distance where Xu Ting's headquarters was located was not too far, and it only took less than ten minutes to be able to return, but Xu Ting's headquarters couldn't retreat very calmly at the moment. Because although the combat area in this area is a very wide plain, Su Jiao is worried that before Xu Ting leads the army to retreat and then converge again, the Huns will change their goals and put it on Xu Ting's department, which is the weakest in overall strength.

If such a situation really occurs, it is not a good thing for Su Jiao.

Of course, it was also very difficult for the Huns to do this. After all, the knight troops of the Qin Army under the command of Su Lan and Chen Heng naturally would not turn a blind eye to such a situation.

It's just that now is not the time to pay too much attention to the safety of Xu Ting's department. Since Su Jiao planned to have a tough encounter with the Huns, he naturally wouldn't do nothing.

Although he was very confident in the combat effectiveness of the battle formation formed by the officers and soldiers under his command, it was undeniable that he was not an idiot, because the idiot knew that in such a situation, it was difficult to effectively resist the number of people or occupy a certain advantage just by relying on the battle formation, and the impact power was not something that ordinary battle formations could resist.

After all, there are more than 50,000 people on the other side. If it was unlucky, maybe the Huns would be able to defeat the Qin army under his command at a relatively heavy price in the early stage.

Such a situation is not what Su Jiao wants to see.

Therefore, Su Jiao mobilized the troops on the front line. After ordering him to retreat and converge, Su Jiao immediately ordered the more than 20,000 infantry troops under his command to be divided into two parts.

Part of it was natural to form a battle formation to guard against the forcible breakthrough of the Huns. The other unit was divided into squads, and these squads, under the command of the corresponding officers, carried out the construction of a system of temporary fortifications.

......

The officers and soldiers quickly removed some of the sacks that had been stored in the wagons and had been used to hold grain. Then the people on the side quickly put their shovels in their hands and packed the dirt with the turf in these sacks.

These sacks, which are filled with dirt, will pile up a ring-shaped obstacle about a meter high in some areas.

The distribution of these sandbag rings is not very regular, but they are not too sparsely dense.

The function of these rings is mainly to weaken the impact force of the Hun riders, after all, if these 50,000 Hun riders really rush over. With the infantry battle formation alone, it is impossible to resist the impact of the opponent.

Therefore, in such a situation, Zhang Jiashi came up with a kind of temporary sandbag position in later generations to improve the survivability of his infantry units against knight shocks.

Of course, such a situation is not strictly enough to reverse this disadvantage, and it can only make it impossible for the Hun riders to assemble a tight formation to continue the attack.

If these Hun riders had ridden over the past, then the role that these sandbag positions could have played. That's all.

And relatively speaking, these sandbag positions are not very good at the defense of the arrows that are thrown down, once the Huns use large-scale projectile suppression, the defensive effect that these sandbags can play can be said to be relatively insignificant.

However, digging up the earth to fill the sandbags and then stacking them did not mean that the Qin infantry would only defend themselves in this way.

After digging a pit with some depth, these Qin officers and soldiers will base some sandbags on the periphery of these pits, of course, the defensive height of this sandbag is not very high, generally about fifty centimeters. However, if you count the depth of the excavated pits, many of the pits enclosed by these sandbags are even higher than the outer ring positions.

Zhang Jiashi did not think of directly training the officers and soldiers under his command, and using the trench excavation of later generations as a means of countering in this regard.

However, after observing the results of his own idea after implementation, Zhang Jiashi had to give up such an idea.

Because it is not too difficult to excavate a trench with a later effect, but once it is necessary to use these trenches to form, it is still too long for these trenches to be excavated.

Perhaps this kind of trench can be useful enough as an additional form of permanent fortification, but it can be said to be quite unreasonable for possible field warfare.

Therefore, in the end, Zhang Jiashi could only choose this temporary defense system, which was not safe, but the time spent was greatly reduced.

............................................................ Dividing line ..........................................

In fact. Such a temporary defense system, such as the kind of defensive rings stacked with sandbags, also has great shortcomings, in addition to the inability to effectively provide defense against the warp strike force mainly from the sky, there is also a weakness in the corresponding force defense arrangement.

After the corresponding tests, it is undeniable that the use of crossbowmen as the backbone of such a defensive ring. It really can play a good role.

But when confronted by the enemy, it is only the crossbowmen who use these rings. If these rings are entered by enemy melee troops, these crossbowmen will be very weak to resist.

But without ranged forces, the defensive effect of these rings will undoubtedly be even worse.

Therefore, after thinking about it for a while, Zhang Jiashi chose to let some special mixed troops serve as the defense team of these rings.

After all, the space enclosed by the ring is not too large, and once the number of people is too large, in terms of the troop configuration during the cold weapon period, it will make the defending troops not have enough combat space.

After more than a week of testing, Zhang Jiashi summed up several more effective ways to build sandbag defense lines.

The first type is, of course, this circular ring of defense. Of course. This defensive circle is not a complete circle, but rather an incomplete circle with a certain notched arc. This gap is naturally entered by the supply personnel.

The second type is a relatively large arc, and this shape of the defense line is more of an enlarged version of the circular defense line.

This arc line of defense can provide more personnel to defend with, and the defense surface is a little larger.

However, this kind of arc defense system requires a longer construction time, so in such a situation, Su Jiao did not choose this arc defense system. Instead, choose the first one, which is smaller, but can be completed more quickly.

The last type is a long line of defense similar to that of later generations. The construction of this defensive system is simpler in a sense, but in terms of defensive capabilities, this defensive line corresponds to the combat of infantry units, after all, many times, this defensive line can be easily broken through by knightly troops. Therefore, Su Jiao did not use this method as a means of resisting the onslaught of the Hun riders in this battle.

Zhang Jiashi also did not think about how much trouble it would bring to the Great Qin Empire if this defense system was used by other hostile forces. But it is undeniable that if the Huns really planned to use this method to fight against the Great Qin Empire in a fixed position, he would not be able to ask for it.

After all, fighting a fixed positional war is not something that the Huns are good at. Because what the Huns were good at was relying on their mobility as a means of harassing and attacking or directly forcing a breakthrough.

Having said that, the main reason why the nomads have always been considered by the Central Plains Dynasty to be a big problem and few Central Plains Dynasty have taken the initiative to attack is because the nomads are quite aware of the corresponding manifestations of guerrilla warfare.

"The enemy advances and I retreat, and the enemy is stationed and disturbs me. When the enemy is tired, we will fight, and when the enemy retreats, we will pursue" can be said to be the true meaning of guerrilla warfare. And for these nomads, their style is like these sixteen words.

After all, many times, these nomads faced the military pressure of the Central Plains Dynasty in the strong period, for example, in the middle and late stages of Emperor Wu of the Han Dynasty, these Huns often avoided head-on conflict with the Han army after their strength was greatly reduced, and only when they had to fight with the Han army, these Huns would not take the initiative to attack the Han army.

Therefore, in the face of such an enemy with combat superiority, even Wei Qing could only directly attack Longcheng, forcing the Huns to fight him head-on in order to defend Longcheng. If this were not the case, Wei Qing might have to lead his troops to run on the desert steppe for a long time, and he might not be able to meet a Hun army or a large tribe with a certain strength.

If Mao Dun was asked to dig his own grave to learn this combat method, Zhang Jiashi would naturally raise his hands in favor, but Zhang Jiashi really wouldn't think that Mao Dun would be stupid enough to follow suit, after all, as Zhang Jiashi's henchman after Xiang Yu and Liu Bang, Mao Dun would do this, and he could really only expect the region to turn in the opposite direction.

Or rather, the sun is coming out of the west......

......

Moreover, in terms of corresponding equipment, few countries can have a combat weapon configuration similar to that of the Qin army, and under the relative equipment advantage, this equipment configuration can effectively offset the disadvantages brought about by this defensive means that are learned by others.

For example, in the case of the Huns, the overall range of the Xiongnu's bows and crossbows was not far, and before these defense systems could play a relative role, the defenders of these defense systems had to pay relatively heavy casualties in the face of the Qin army's strong bows and crossbows.

Therefore, in many cases, a defense system can play a corresponding role, and the most important thing is to see whether this defense system can effectively give full play to the advantages of its army's combat capability.

Of course, Zhang Jiashi did not think about one point, that is, to exert the ability of gunpowder weapons as much as possible.

But it is undeniable that the current gunpowder weapons are really not enough to exert their combat effectiveness. Except for the fireworks that were used as signal flares, Zhang Jiashi did not have other gunpowder weapons that were basically still being tested or even vetoed by Zhang Jiashi.

......

As a trend of later generations, the efficiency of gunpowder weapons is naturally able to be used as a means to basically withdraw cold weapon warfare on the basis of later generations.

But in the current situation, Zhang Jiashi has to admit one thing, that is, he is currently using a large number of immature and even cheating gunpowder weapons, which can only be a manifestation of the door of the brain being caught by the door.

Not to mention anything else, the explosive pack used in the last fierce battle between the Great Qin Empire and the Donghu people on the Great Wall was very ineffective, and its corresponding incidental weight was even more unacceptable to Zhang Jiashi.

After all, after removing the weight of their own weapons and armor, there are really not many things that a Qin officer and soldier can carry, on the premise that they must ensure the speed of the march.

Of course, such explosives packages can also be grouped together......

And Zhang Jiashi said very directly: "A large fireworks of several hundred catties of gunpowder should look good." (To be continued.) )
