After returning to the camp of the Zhao army, Gao Yuan also reported the results of this attack to Li Mu, and Li Mu was also very happy when he learned about it, since the war between Zhao and Qin, Li Mu also really saw the opportunity to defeat the Qin army for the first time.

Although the plateau attacked this time, the number of Qin troops eliminated was less than 5,000 people, and it seemed that the results achieved were not great, but they burned a large amount of grain and grass materials in the Qin State, which is the most important thing, Li Mu is a person who is proficient in the art of war, of course he knows the importance of logistics supply to the war, without grain and grass, without the supply of ordnance and materials, no matter how many the number of the Qin army is, no matter how strong the combat effectiveness is, it is useless.

Although before the start of the war, Li Mu had already formulated the tactics of attacking the logistics supply line of the Qin army according to the construction of the plateau, but Li Mu still had some doubts about the effect of this set of tactics, after all, although since the Warring States period, there have been continuous wars between countries, but no one has used this tactic of attacking the enemy's supply line, and the main reason is that the ability of the cavalry in this era is not enough to undertake such a task.

However, the arrival of the plateau accelerated the development of the cavalry in this era, and Guan Jian did not mean that he brought new horse furniture to enhance the combat effectiveness of the cavalry, but brought a new concept of how to use the cavalry, so that the cavalry could truly give full play to its own combat effectiveness. With the results of this sortie, the Zhao army finally found a way to defeat the Qin army.

Of course, it is far from enough to rely on only one sortie, after all, this blow cannot cause fundamental casualties to the Qin army, and it is necessary to make persistent efforts to continue to attack, continuously attack the Qin army's relief line, and constantly attack the Qin army's logistics supply, so that if you persist for three or four months in a row, it will make the Qin army feel unsustainable, and at that time, the Qin army may have to retreat.

Therefore, after the plateau was repaired in the camp for three days, and after the bodies of the soldiers and horses were restored, they immediately led the army to attack again. Three days later, Gao Yuan led his army to attack a convoy of the Qin army again, burning all the more than 2,000 truckloads of military supplies.

However, this time the Qin army also raised its vigilance, and after learning that the Zhao army was attacking, it immediately temporarily stopped transportation, and Wang Jian mobilized 50,000 cavalry troops and divided them into five ways to attack, and they must destroy this Zhao army.

And the plateau also led the Zhao army, and the five Qin army to start a chase battle, the two sides chased each other between the vast mountain area between the enemy and the well, but the Zhao army under the command of the plateau, spread around and moved, after six days, the two sides had four battles, the Zhao army won three and drew one, and killed more than 3,000 people of the Qin army, although the Qin army was ready to surround the Zhao army three times, but let the Zhao army escape, by its last, it was also very thrilling, when the Qin army had concentrated four cavalry armies, the Zhao army surrounded on all sides, But Gao Yuan, who commanded the Zhao army, took advantage of the blackness, inserted between the gap between the two Qin armies, broke away from the encirclement of the Qin army, and on the contrary, launched an attack from behind one of the Qin troops, and as a result, killed more than 1,500 Qin troops, and then broke away from the battle before the other Qin armies arrived, and returned to the camp of the Zhao army.

Although this Zhao army only attacked a transportation team, but it caused the Qin army to dare not send supplies to the front line for more than ten consecutive days, which also had a great impact on the Qin army, after all, nearly 400,000 Qin troops, the various materials to be consumed every day are quite amazing, although there are also a large number of materials in the barracks, but the place of the barracks is limited after all, and it is only about a month at most, so almost every four or five days, a batch of materials must be replenished, and there is no material supply for more than ten days, and everyone is a little panicked.

Fortunately, this time it only stopped for twelve days, and as a new batch of supplies was delivered to the Qin army's camp, everyone was also relieved. But several of the main generals of the Qin army knew that the Zhao army would never stop there, and would definitely come again.

However, this time through the attack, Wang Jian also found a temporary way to deal with it, that is, to send 30,000 cavalry troops, divided into ten teams, to patrol back and forth on the road between Qiu You and Jingcheng, and also strengthened the protection of the transport team, and stipulated, reduce the scale of transportation, adopt the method of multiple transportation, each transport team can not exceed 2,000 vehicles, the protected Qin army must reach the ratio of two people to protect one car, and the civilian service is also equipped with weapons, using the same tactics as when the Qin army marches, Once they encounter the attack of the Zhao army, they immediately defend on the spot, wait for other Qin troops to come to the rescue, and never escape without permission.

Although these measures of Wang Jian increased the burden of the Qin army, but it was also quite effective, the third attack of the Zhao army encountered relatively big trouble, the plateau attacked the Qin army's transport convoy twice in a row, both were met with stubborn resistance by the Qin army, and even the civilian servants took up arms to resist the attack of the Zhao army, which also made it difficult for the Zhao army to defeat the Qin army guarding the transportation of supplies in a short period of time. And the time dragged on, and the reinforcements of the Qin army also arrived, so the Zhao army also had to abandon the attack and retreat, these two attacks only burned dozens of transport vehicles.

And when the third attack on the convoy, Gao Yuan was also a little anxious, so the timing of the retreat was not mastered, of course, he also hoped to destroy this convoy, but the Zhao army had not yet broken the defense of the Qin army, and was besieged by four Qin cavalry armies. Fortunately, the combat effectiveness of the 2,000 new cavalry army after the Zhao army was extremely strong, and they broke out of the encirclement of the Qin army in one fell swoop and escaped, but they also lost nearly 500 people, of which the new cavalry army lost nearly 150 people, which was also the largest loss suffered by the Zhao army since the attack.

The third attack of the Zhao army did not achieve much success, and this result also reassured Wang Jian, believing that he had found a way to deal with the attack tactics of the Zhao army.

After retreating to the Zhao army's camp, Gao Yuan and Li Mu also discussed the results of this attack in detail. Although the third attack of the Zhao army was basically a failure, the attack tactics themselves were not wrong, and they were still the tactics that the Zhao army should mainly use at present, but some changes should also be made in the use of the body, after all, the Qin army had already found a way to deal with it.

After discussion, Zhao Jun also found a way to deal with it, that is, it was not possible to attack the transport team of the Qin army by attacking only one way, and it was necessary to attack separately from multiple roads, so that the Qin army could not take care of it left and right, so as to break this way of dealing with the Qin army. And after three sorties, the cavalry of this Zhao army also has rich experience in attacking, and is more familiar with the terrain, so with these cavalry as the main body, it is divided into four Zhao armies, and each Zhao army is still 3,000 cavalry, taking turns to attack. Again launched an attack on the Qin army.

Although the 2,000 new cavalry was divided into four or 500 troops, and the combat effectiveness was indeed weakened a lot, the tactical characteristics of the cavalry's flexibility, speed, and changeability were still retained. At the same time, after the first three sorties, Gao Yuan also found that the two thousand cavalry troops were all used together, and some Lang was indeed useless. Therefore, it is better to use it in a decentralized manner.

Moreover, in terms of the attack tactics of the club, the plateau also formulated three regulations according to the first three sorties: First, the Zhao army's attack team should take turns to attack in a group of two, and the interval between each group was five days, and the time of each sortie was limited to ten days, and within ten days, it was necessary to return to the Zhao army's camp to repair and replenish, and after five days, attack again.

If you can't find the opportunity to attack at night, then you must set up an ambush in the middle of the transport team, stop the waist and attack the transport team, or let the transport team attack from behind, and it is absolutely forbidden to attack the transport team from the front. And each sortie was mainly to destroy materials, not to kill and injure the soldiers and civilian servants of the Qin army, and it was not required to destroy the belongings of an entire transportation team at one time, and it was also a victory to be able to destroy some of the materials. Then look for other opportunities, either to attack the transport team multiple times, or to find other targets.

Third, once the Qin army's patrol cavalry is discovered, no matter what the result of the battle, they must immediately retreat, avoid the Qin army, and must not fall in love with the battle, and they are not allowed to engage the Qin army's patrol cavalry. Only when two or more Zhao troops were concentrated, it was allowed to engage the Qin patrolling cavalry, but only ambush tactics were used, and it was absolutely forbidden to engage the Qin patrolling cavalry head-on.

Fourth, the Zhao army's Jingcheng battalion also sent a small force to attack the Qin army's battalion, diverting the attention of the Qin army, combining the frontal battlefield with the flank battlefield to respond to the attacking team.

Li Mu also very much agreed with the four points formulated by the plateau, and it was the fourth point proposed by the plateau, which was particularly appreciated, because this means that the plateau was not a single tactic to attack the Qin army's transport team, but from the overall aspect of the entire campaign, especially for the plateau's sentence "the combination of the frontal battlefield and the side battlefield" Li Mu thought it was very subtle, and it could be said that he had mastered the essence of the way of using troops. As long as these four points of habitual side are adhered to, then Zhao Jun's fourth sortie can be successful.

So Gao Yuan led his army to attack again, attacking the transport team of the Qin army. And Li Mu also ordered the Zhao army of the Jingcheng battalion to attack and launch an attack on the Qin army. Although the number of Zhao troops in each attack was not large, the number of sorties was very large, and the Qin army also had to face it, and as a result, in four or five days, the two sides fought more than ten battles in a row, and basically won and lost each other, and no one had much to lose.

But at this time, the Zhao army had already launched the fourth military operation to attack the Qin army's reinforcement line, and this operation, both in terms of time and intensity, was much larger than the previous three.
