The army led by Duoduo arrived at the city of Datong a day later than Cao Yue expected.

According to the speed of the Jiannu army's earlier march, they could have arrived at the city of Datong two days earlier, but after reaching the front line of the Great Wall, Duoduo's men and horses were once again harassed by unknown people, paying a relatively large price, and thus delaying the journey.

Duoduo knew that this was Cao Yue, after detecting the whereabouts of the Qing army, and sent elite men and horses to attack along the way to slow down the attack of the Qing army and cause trouble for him.

This time, the Qing army originally wanted to hit Cao Yue by surprise, but it seems that it is about to miscalculate again.

Duoduo had no choice but to report the situation to Dolgon, the queen of the palace, and strictly ordered all the generals under his command to strengthen their vigilance and not give the Ming army a chance to take advantage of it. However, no matter how strong the vigilance of the generals under his command was, they were still attacked by the Ming army from time to time, paying a lot of price, and the speed of movement was greatly delayed.

Duoduo knew that the encounter of the Qing army's southern expedition this time was somewhat similar to the last time, and it was impossible to reach the city of Datong unnoticed, and it was impossible to catch the Datong defenders by surprise.

The situation of the last southern expedition, Duoduo told Dorgon in detail, including the situation encountered along the way, as well as the situation in the Datong area, including the fact that a large number of people were moved into the city, and the army could not find people and could not collect food. Since the whereabouts of the Ming army have been discovered this time, the same situation will definitely happen, fortunately, this time it is spring, the war horses don't worry about forage, and the army has brought enough food.

In the end, the vanguard led by Duoduo still arrived at the city of Datong "safely".

The special training personnel sent by Cao Yue paid a certain loss, but they dealt a big blow to Jiannu, and more importantly, delayed their trip. When Duoduo led his army to Datong City, Sun Chuanting and Cao Yue had already made the necessary preparations for the war, and the Datong army was neatly guarding the city, waiting for Jiannu's siege.

Duoduo is still quite strategic, he knows that the defenders of Datong are ready to fight, so he is not in a hurry to attack the city, but after arriving in Datong, he seized the time to prepare for the siege, and bluffed, wanting to overwhelm the defenders of Datong in momentum.

Five miles away from Datong City, a large number of camp tents were erected, and the woods around Datong were also cut down in large quantities, and were used by Jiannu to make ladders and other things for siege. Tempting the siege and testing the depth of Datong is also what Duoduo must do, and after the initial preparations, he also gave the order to attack the city. At this time, Azig's follow-up army was still about half a day's journey from Datong, and the army led by Dolgon himself was still about a day's journey from Datong.

The first siege mission was not given to the Han army led by Geng Zhongming.

After Geng Zhongming almost wiped out his entire army on the last southern expedition with Duoduo, Dolgon did not put him to death, but gave him a chance to atone for his sins, and then pulled out 12,000 newly recruited Han soldiers and horses and handed them over to him for command.

Coupled with the original troops, Geng Zhongming now has 20,000 men under his command, of course, he very much wants to atone for his sins in order to gain the approval of his master Dorgon, so he repeatedly asked for orders in this battle, wanting to lead the army to attack the city first, but Duoduo refused.

Duoduo knows that the combat effectiveness of the more than 10,000 Han troops under Geng Zhongming's command is now that these troops who have just been recruited and most of them are the surrender of the original Ming official army, which is completely a group of rabble.

The Eight Mongol Banners under the command of Duoduo were the men and horses led by Chahan of the Korbi Division.

The Horqin tribe was the first of all the Mongolian tribes to form an alliance with Jiannu, and many of the imperial concubines in the Manchu royal family were from Kormi, including Empress Zhezhe, Concubine Zhuang Bumubutai and several other concubines Namu Zhong, Hailanzhu and others, it can be said that the women of Korqin filled the palace of Manchu Jiannu. After Huang Taiji's conquest of Mongolia, the Mongol tribes were suppressed by the reduction of Dingding, and only the strength of the Horqin tribe was strengthened.

Now that Huang Taiji is dead, in addition to Dolgon, the greatest influence on the Manchu Qing Dynasty politics is the Empress Dowager Zhezhe, and the mother of Emperor Fulin, Bumu Butai, the two aunts and nephews are the daughters of Kormi, and of course they have to maintain the power of their mother's tribe. ** The women married to Hachi's second son, Dai Shan, and his fifth son, Mang Gurtai, were also from Kolmi, so Kolmi's status in the Manchu state became higher and higher.

Today's Horqin tribe is composed of four tribes, the long branch is led by the prince of Horqin, Ukshan, the leader of the two branches is Chahan, the third branch is Sonam, and the fourth branch is Manzhu Xili. Probably due to nature, the Mongols were inferior in strategy to the Jurchens, which should be an important reason why the Mongols, who were the majority, were finally conquered by the Jurchens. Although the women of Kolbi are all smart and beautiful, the intelligence of the men does not seem to be as good as that of other tribesmen.

There was a very important reason why Dorgon had Chahan join Dord's vanguard army, and Dordor had his men attack Datong first.

Chahan is reckless, irritable, belligerent, and in layman's terms, he is powerful. Duoduo ordered his troops to attack the city first, making it clear that Chahan and his 20,000 Mongol cavalry would be killed under the city of Datong.

Dorgon and Duoduo hoped that the destruction of the Chahan tribe would arouse the hatred of the entire Korqin tribe against the Ming Datong army, so that they would never have a chance to unite again. Because the Kol tribe was also a vassal to the Ming Dynasty, most of the leaders of the Kol tribe had accepted the canonization of the court of the Great Dynasty, and now although the Mongolian tribes have been conquered by the Jurchens, no one dares to guarantee that the Mongolian tribes, including the most powerful Kormi tribes, will not become the enemies of the Jurchens in the future. This move can not only arouse the hatred of the Kormi people against the Ming Dynasty, but also make the Mongols fill the Jurchens with cannon fodder.

However, Chahan and his 20,000 tribesmen had no way of understanding these things, and they were complacent that Dodor had entrusted them with the task of the first battle. Although the four Mongol tribes and the other three also followed the expedition, the first attack fell on whoever it was, indicating that this tribe was more recognized by Dolgon, and as long as it made war achievements, its status would be higher in the future.

The Mongols did not experience the defeat of Datong last time, they did not know the strength of the Ming army's firearms, and thought that the Han army's combat effectiveness was too poor, so they ended up in a crushing defeat. In the last battle of Songshan, although the Mongols were also attacked, they did not think that the Ming army's combat effectiveness was very strong, and the later Ming army's crushing defeat made them forget the tragedy of the attack on Ru*Fengshan.

After accepting the task assigned by Duoduo, Chahan was very excited and issued a military order to Duoduo, saying that he would definitely attack the head of Datong City and wipe out all the Ming troops who dared to arrive.

While gloating in his heart, Duoduo also politely wished Chahan a victory, as long as Chahan led his troops to attack the head of Datong City, he personally asked Dolgon for credit.

With Duoduo's words, Chahan and the 20,000 tribesmen under his command were even more excited as if they had been beaten with chicken blood, and they couldn't wait to attack the city at night.
