The next day, Yang Yifei stepped on his own war horse in the blessing of Meng Yi, Li Xin, Nangong Yan and others.

Only then did he understand why Meng Yi had to attack after the sun rose, they were in the east and the enemy camp was in the west, and the sun had just risen at this time, and he was behind them.

First, using the sun as a background will enhance their power, and second, the enemy will face the sun and will inevitably be dazzled by the sun.

The enemy's bow and crossbow are not as good as the Great Qin bow and crossbow, and if they lose their accuracy due to the dazzling sunlight, their own side will undoubtedly be safer.

If they use projectiles, the enemy will not even be able to see the direction of the arrows, and they will not be able to dodge and resist, which will obviously greatly increase the casualties.

In the Three Kingdoms at the end of the Han Dynasty, Cao Cao used this tactic to defeat Yuan Shao's 110,000 army with 20,000 horses, and Cao Cao suffered about 8,000 casualties in that battle, and Yuan Shao lost 100,000 troops, completely reversing the situation in the late Han Dynasty.

There are too many ways to march and fight in ancient times, and Yang Yifei feels that he still has something to learn.

Later generations did not pay attention to this at all, because the brim of the military hat was used to block the sun and avoid the eyes from being swayed by the sun when aiming, so even if the sun was in front, it would not affect the soldier's aiming and shooting.

Tactics for this attack Yang Yifei had already agreed with the two 2500 masters and the 4 500 masters yesterday, and they would be divided into two groups and launch an attack on the enemy army in a relay way.

After all, there is a limit to the number of times the archers can shoot their bows, and it is impossible to shoot all the time, and when a thousand of them attack, the other thousand will stand by, and then alternate.

And after they set off for a while, Meng Yi would send a large army of infantry to follow them, and after the enemy scouts were cleared by the archers along the way, the enemy army could not grasp their movements, and they could give the enemy a huge surprise at any time.

The middle lane was pushed all the way by the archers, and the other Qin scouts mainly concentrated their forces and made every effort to clear the enemy's flanks and surrounding scouts.

After getting ready, Yang Yifei raised the longbow in his hand and shouted, "Archer cavalry, attack." ”

"Sigh the law ......"

The neighing of war horses sounded in the field, and the two thousand cavalry archers urged the horses to trot in the direction of the target.

This place was thirty miles from the enemy camp, and naturally they would not have ridden their horses in vain at the beginning.

In order to maintain the endurance and agility of the war horses, the archer cavalry was reduced to the extreme, and they did not wear a piece of armor on their bodies, except for carrying a longbow and forty arrows, as well as two days of dry food and drinking water, they only had a short sword on their bodies.

The short sword was not used for close combat, but for cutting off the head, because to calculate the number of levels of military decapitation, the head of the enemy army was used as evidence.

Yang Yifei didn't care about other troops, but his archers and cavalry troops, he stipulated that no matter how many enemy troops were shot in a battle, the first rank would be divided equally.

Because they are all long-distance arrows, a round of arrows rain down the ghost knows who shot how many enemy soldiers, and the archer troops are relatively safe, and the military merits are no different from white pickup, so this rule is fully supported by the archers.

If the beheading is less than two thousand, not everyone can be assigned military merits, then the person with the lowest title will be given priority, Yang Yifei hopes that all the troops under his command can have a knighthood, even if it is a mere public servant, after all, they can eat better than ordinary soldiers.

There are many advantages of this 20-level military merit title system, and the biggest effect is to encourage soldiers to fight bravely to kill the enemy, but it also has its drawbacks.

For example, some units that are not cohesive, or soldiers from two different units, will kill each other on the battlefield in order to compete for military merit.

This kind of disadvantage is relatively light, and what is even more terrifying is that some ruthless and black-hearted sergeants will slaughter people for the sake of military merit in order to pretend to be the head of the enemy army, which is the so-called "killing good and risking merit".

Of course, these two situations were still more common in the years when Shang Ying had just changed the law and the first emperor launched the unification war, but they were rare in this era.

When cleaning up the battlefield, the generals will keep an eye on the battlefield, and if there is infighting over the head, the instigator can be directly punished with capital punishment.

And if it is now unified, the places where wars take place are basically on the frontiers, and the only level that the army can cut is the enemy's.

Once the war is over, the troops will gather their divisions, not only will they not have the opportunity to slaughter the people again, but they will no longer record their military exploits at this time, so naturally there will be no situation where the heads of the people will be used to fill the military merits.

If the first emperor begins to expand his territory and fight to the lair of foreign tribes in the future, this situation will most likely still occur, which cannot be stopped, and can only be strictly controlled by army generals.

The generals can only guarantee that this situation will not occur as much as possible, but they cannot guarantee that it will never happen.

……

The archers set off for less than half an hour, walked about ten miles, and after crossing a hill, they encountered the enemy's scout light cavalry, and Yang Yifei shouted: "Shoot freely at the enemy scouts." ”

After saying this, he raised his hand and shot an arrow at an enemy scout eighty or ninety paces away, hitting the opponent in the chest, and then the soldiers around him also shot arrows.

There were ten scouts encountered this time, and they were all shot in one shot, and they didn't even have a chance to fight back.

Originally, the effective distance of a stone bow was only sixty paces, and the accuracy of more than sixty steps could not be guaranteed, and the enemy scouts encountered were eighty paces away from them, but they were all buried under the archers' arrows.

This is because Yang Yifei not only trained the cavalry archers in riding and archery, but also taught them ballistics into a way that they could understand.

After a lot of experiments, Yang Yifei summed up a set of data, that is, for every ten steps away from the range, how many degrees of elevation angle need to be raised.

After several months of continuous practice, the archers basically mastered this set of data, even if they were a little dull, but through countless trainings, practice makes perfect, diligence can make up for clumsiness, and finally found that law and gained experience.

The archers were now able to maintain accuracy between eighty and ninety paces, which meant that their effective range had increased from sixty to eighty.

At this time, they shot the scouts, in fact, they used a small angle of projectile, thirty or forty people shot arrows, and the enemy's ten horsemen naturally could not escape the catastrophe.

This group of scouts was poisoned because they happened to be blocked by the mound, and they couldn't find the archers in time, and then the enemy scouts were basically not spared in encounters like this one, and the scouts encountered in the open area, Lao Yuan saw them turn their horses and ran away.

Yang Yifei also didn't let his subordinates pursue, it was not cost-effective to waste horsepower for a few scouts, he wished that the scouts would bring the news back, so that the other party could get ready, line up the array and wait for them to shoot.

If they really quietly kill in front of the enemy's camp, as archers, they can't take advantage of the opponent's unpreparedness to enter the camp.

If the enemy army is not arrayed, the killing efficiency of the arrow rain will be greatly reduced, so Yang Yifei did not plan to extinguish the enemy scouts along the way from the beginning, as long as he drove them back and could no longer go forward to inquire for information.
