"Both the East Battalion and the West Battalion have left 20,000 horses led by the deputy general, and you will lead the rest of the men and horses to gather here, concentrate the greatest strength to attack the city, and break the defense of this Jiangdu City with a point!" Yang Xuan ordered. The siege can only be attacked by one, their troops are already smaller than the people of Jiangdu, if the comprehensive siege is dispersed, the war will drag on indefinitely, so if the troops are less than the defending side and the overall strength is stronger than the defender, they can only take a concentrated attack.

"Yes!" Zhang Xutuo and Qin Shubao and others bowed down, they were also worried that it was not easy to attack the city wall with the 50,000 horses in their hands, and now they only left a small number of men and horses around, and they commanded a large army to join the army, although all the generals are together, the opportunity to fight needs to be sought, but as a party commander, it is even more impossible to fight, after all, it is necessary to control the overall situation, just like the king of Qi cannot personally lead his troops to attack the city.

After breakfast, nearly 200,000 troops converged in the North Daying, looking at the majestic and heroic army, the hearts of Yang Jun and the generals were surging, who would have thought that he was an ordinary person (Yang Yong was only a small soldier in his previous life), and he could actually become the commander of this army.

"There is no moat in the north of Jiangdu, and it is a smooth road, which saves a big difficulty in filling the river." Yang Jun looked at the Jiangdu City without a moat in front of him on the horse, like a stripped white sheep, waiting for the arrival of the wolf. After all, the Jiangdu is adjacent to the Yangtze River in the south, and if you dig a moat, it won't take much effort, and the moat dug out must be deep and wide. Maybe it's because Jiangdu was not valued before Yang Guang took chance, and before the opening of the Grand Canal, Jiangdu was far less prosperous than it is now, and it is precisely because of this that I feel that there is no need to dig a moat, and after Yang Jian set Jiangdu as the capital and the Grand Canal was opened, the national strength of the Sui Dynasty has reached its peak, and I would never have thought that Jiangdu would one day become a battlefield, and all these unknown reasons brought great convenience to Yang Jin's siege.

"Lord Wang, it is Yuwen Chengji who guards the north gate, this person is not simple." Cheng Yanjin walked to Yang Yong's side at this time and said, after a battle with Yuwen Chengji, Cheng Yanjin seems to be more calm, and now he knows that he values his opponent.

"Yes, Yuwen Chengji is good, but we are stronger, this king said, we must pay attention to every opponent, but now it is a large army of combat, this king will teach you again, you must despise the enemy strategically, and attach importance to the enemy tactically! No matter how strong the enemy is, there is always a weakness, and you must have the courage to move forward! "It's good to know that you value the enemy, but you can't let the enemy frighten you, the enemy is also a human being, and if you are a human being, you will have weaknesses, and you can only achieve victory if you have the confidence to defeat the enemy first.

"Yes!" Cheng Yanjin, Qin Shubao, Luo Shixin and Su Dingfang all nodded solemnly, almost all the military theories they accepted in the army were from Yang Jun, or from Li Jing's realistic interpretation of Yang Jun's military theory, so they would remember every sentence of military theory that Yang Jun said that contained truth. However, Zhang Xutuo did not accept much of Yang Jun's military theory, after all, Zhang Xutuo is newly attached, and Zhang Xutuo is a famous general who has been famous for more than ten years, so it may be a little difficult for this kind of person to accept a new theory in its entirety, but it does not hinder his understanding of Yang Jin's words. Li Jing is different, he has never been a military strategist, just studying military theories, until he was pulled into Qingzhou by Yang Jun and slowly moved towards the direction of a military strategist, and he could only be called a military strategist after his own military works came out.

"General Zhang!" Yang Xuan shouted at Zhang Xutuo, who was contemplating far away from him, Zhang Xutuo was not as close to Yang Xuan as Luo Shixin and the others, because these young Zhuang factions were brought out by Yang Yong, and they were more emotionally close.

"The last general!" Hearing Yang Yong's voice, Zhang Xutuo slapped his horse to Yang Yong's side, clasped his fists and waited for Yang Yong's order.

"You led the men and horses of the headquarters to dig nearby with sacks, and this king asked you to build a mound as high as the city by leaning on the Jiangdu City, can you do it?!" Although there is less procedure for filling the river, Yang Yun does not plan to start attacking the city directly, he has time, many siege equipment has not been brought, and with the gundam of Jiangdu City, even if there are ladders and siege vehicles, it will not be of much use, but without these equipment that can directly attack the city, don't you have a brain? Why is the Mongolian Iron Horse so powerful? Why does every city have to go down? Did they rely on foot soldiers to attack the city? Of course not, when it comes to siege, this is the shortcoming of the nomadic people, but they are able to attack the city because their cavalry plays an important role.

In fact, Cao Cao also used the mound of earth to attack the city during the battle of Guandu, but the efficiency was much lower, and it was difficult to work, but it was different to use cavalry to mound, the cavalry was highly mobile, and the defenders were difficult to cause great damage to the highly mobile cavalry, which ensured the efficiency of the mound. Of course, in addition to piling up earth to siege the city, it can also be built into a siege, Li Shimin and Wang Shichong's battle of Luoyang is a typical example, Yang Jun's mind has many examples of these sieges, although they cannot be perfectly copied, but the principle is still known.

Although the results are faster with the carts brought by Yang Xuan, after all, there are hundreds of thousands of defenders in Jiangdu City, and if they attack it, they will have to face a huge counterattack, and if they are not good, they will suffer huge losses, so once they dare not guarantee that they can completely destroy the other party in a war, then they have to slowly wear off the morale and resistance of the other party, and the war is also a psychological warfare.

"Yes! Subordinate items on the head guarantee! Zhang Xutuo woke up instantly after being puzzled, and looked at Yang Jun's eyes full of admiration, who said that cavalry can only charge on the plain, and now in the hands of this prince, the cavalry can attack the city, and it is the kind of existence that can definitely attack the city wall.

"Okay, then the first task of the siege will be handed over to you first." Yang Jun is very satisfied, worthy of Zhang Xutuo, he can react as soon as he mentions it, if it weren't for the fact that the people who know the cavalry battle well really can't turn around all of a sudden, the Jiangdu city wall is tall, and there is no problem with the passage of two horses side by side in the aisle of the city, once the cavalry goes to the city, it is definitely an invincible existence.

"Dingfang, you follow General Zhang, learn from General Zhang!" Yang Xuan also arranged for Su Dingfang to follow Zhang Xutuo to carry out the task together, Su Dingfang does not lack experience, but lacks systematic learning and prestige, Zhang Xutuo will be old after all, and Su Dingfang is the time of blood and strength, his appearance just gave Yang Jun the choice of the cavalry commander in his heart to make a conclusion, Luo Shixin is undoubtedly the most fierce person under his account, but it is not suitable for commanding Yang Jun's preset cavalry, although Su Dingfang's martial arts rank low, but full of blood, very suitable for the cavalry, what is called the horse of the tiger and wolf? How can you rule without blood?

"Qin Qiong, you command the trebuchet to interfere with the defenders on the city, and reduce the obstruction for General Zhang! Luo Shixin! Cheng bites gold! The two of you lead the rest of the cavalry to roam around, pay attention to the movements of the defenders, and support or respond if the situation changes! ”

"Now, let's get started!" Yang Jun pulled out his long sword and pointed directly at Jiangdu City!
