Wang Chengping originally wanted to launch a strong attack on the Jiannu army under Abatai's headquarters with a thunderous momentum, disrupt Abatai's offensive on Tongzhou, and force Abatai to give up attacking Tongzhou City, but just when he led his troops to approach more than 30 miles northeast of Tongzhou, and was waiting for a little rest, he was about to lead his troops to attack the Jiannu army, but he received an edict from Xiao Tianjian.

After Wang Chengping received the order, after thinking about it for a while, he immediately understood Xiao Tianjian's intentions, and after looking at the map, he immediately bared his teeth and laughed, and smiled at the herald: "The last general will obey the holy commandment, brother go back and tell the saint, please rest assured, the last general will not mess things up!" As long as the Holy Lord defeats them, the last general will guarantee that they will not be able to get out! ”

After sending away the heralds sent by Xiao Tianjian, Wang Chengping began to arrange, he first gave up the idea of gathering troops to attack the Jiannu army, and then began to divide the cavalry under his command, sent out one by one, and marched towards the Tongzhou area, he gave these cavalry orders not to fight hard with Jiannu, so that they should seize the opportunity to keep attacking the Jiannu army, and in the way of hunting, the rangers scattered by Jiannu were cleaned up, and seize the opportunity to bite on Jiannu if they can, And ordered these cavalry not to unfurl the flags and expose their numbers, so as to confuse the Jiannu side, so that they could not figure out how many people and horses of the Dazhong Army came, and lay the foundation for Xiao Tianjian to lead the troops here to fight with Jiannu in the next step.

He himself led the main force of 4,000 cavalry men and horses, chose a place to settle down, released many groups of scouts, formed a cordon around them, shielded their whereabouts, and ordered the scouts to keep a watch on the Jiannu army in the direction of Tongzhou at any time, in case they could take action at any time.

Just when Wang Chengping was adjusting the layout, the fine work in Tongzhou City also received a letter from the flying pigeon, and learned of Xiao Tianjian's instructions to them, so they immediately took action and began to contact the generals of the defenders in the city, and first found Tang Tong in the city, so he dispelled Tang Tong's idea of abandoning the city and fleeing again.

After Xiao Tianjian took the Tianjin Guard, he did not do any rest, leaving the baggage battalion to take over the Tianjin Acropolis, and then he led the remaining 25,000 soldiers and immediately headed towards Tongzhou City.

This time, in addition to mobilizing the men and horses led by himself, Xiao Tianjian also called Wang Chengping's department and Diao Zheng's department, but Diao Zheng must not have time to catch up with this battle of Tongzhou at the moment, at this time Diao Zheng is still far away between Zunhua and Jizhou, and is marching in the direction of Miyun, even if he receives an order now, it is too late to rush to Tongzhou to participate in the battle, so Xiao Tianjian simply ordered Diao Zheng to divide the troops under his command into two, and a group immediately turned around and returned to Shanhaiguan, and he himself led the remaining half of the men. Lightly armed and rushed to Miyun at the speed of a rapid march, recaptured Miyun County and blocked the Huangyakou Pass.

At this time, the entire Dazhong army in Gyeonggi took action, and even Li Lingfeng, who is now temporarily sitting in Xuanda, quickly learned the news that Jiannu had broken through the pass from Miyun Huangyakou Pass, so he quickly began to gather troops in Xuanfu, and reinforced, and reinforced, Juyong Pass, which had been defended by them, and strengthened the defense of the Xuanda area, in case the Jiannu army suddenly invaded the territory of Xuanda from these passes, in that case, Xuanda would probably be ruined again!

Abatai's breakthrough through the Huangyakou Pass also had a great impact on the Dazhong Army, and after they drove straight in, they also cut off the connection between the Shanhaiguan area and Xuanda, forcing a batch of materials that had been prepared to be temporarily unable to be shipped from Juyong Pass to the direction of Shanhaiguan again.

However, this kind of impact, for the Shanhaiguan defenders, is not too big a problem at the moment, Xiao Tianjian has opened up the entire canal at this time, so that the materials of the Dazhong Army can be basically transported to Tianjin Wei on the Grand Canal, and Li Xin, Luo Li, Diao Zheng and others rushed to Shanhaiguan, they have also opened up the Tianjin Wei to Shanhaiguan line, and controlled the road here, so even if the material support from Shanxi is lost, the materials that were then transported from Tianjin Wei It will completely replace the supply of materials from Shanxi, and greatly exceed the amount of materials that Shanxi can sustainably provide, which is also the main reason why Xiao Tianjian insists on going north along the canal and opening up the Grand Canal.

While Xiao Tianjian was busy mobilizing people, Abatai and Haoge basically didn't know anything about the situation of the Dazhong Army, they only knew that they had to speed up their movements, quickly conquer Tongzhou City, and obtain enough food to support their needs in the short term, so that they could survive in the pass.

But Abatai and Hauge are not the kind of brain-dead, although they broke through the customs this time, but they also understand that this time they entered the customs, I am afraid that it is much more dangerous than the previous years when they Jiannu entered the customs, and now the protagonist they have to deal with is no longer the Ming army that they have been bullying for decades, but has been replaced by the same fierce as them and even surpassing their Dazhong army, so they entered the customs this time, a little less arrogant, but a little more careful.

After killing all the way to Tongzhou, they were afraid that there would be a large number of Dazhong troops nearby, so Abatai and Haoge besieged Tongzhou City, but at the same time released a large number of rangers, so that they could patrol around Tongzhou, while grabbing some food and women for their use, while probing the news of the Dazhong Army nearby, and opened a cordon on the periphery of Tongzhou to prevent being raided by the Dazhong Army.

However, although Abatai and Hauge are more careful this time, but Abatai has no intuitive feeling of the strength of the Great Chinese Army, unlike Hauge, who has seen the brave and good fighting of the Great Chinese Army, the last time Chongzhen was at the end of the eleventh year, when Dolgon led the troops into the customs, Abatai was left outside the customs, so Abatai only heard that the Xingtian Army was very powerful, but he did not really understand the fierceness of the Xingtian Army, so psychologically, the pressure of Abatai is not very great, but after Haoge entered the customs, seems to be much more cautious than Abatai, which makes Abatai somewhat look down on Hauge, the "crown prince", and feels that this Hauge is a little too bold.

In Abatai's view, the Dazhong Army may be more powerful, but the strength of the Dazhong Army is only relative to the Ming Army, when it is far less powerful than their Jianzhou warriors, the last time Dolgon, Haoge they encountered the Xingtian Army and suffered a big loss, mainly because they were too light on the enemy, this time he led the troops into the customs, as long as he was a little more careful, he expected to meet the Xingtian thief, and he was expected to use the strong bow and crossbow of their Jianzhou warriors, and they would never suffer again.

Over the years, Abatai has fought with the Han people with his father wild boar skin and brother Huang Taiji, which has already formed a psychology for these Jiannu, and there is absolutely no problem for them to fight three Han barbarians.

But the Han barbarians also have their strengths, that is, defending the city, which most of the Jiannu agree with, but if they are put in the field of wave fighting, the three Han barbarians are not necessarily the opponents of their Jianzhou Erlang.

Therefore, although Abatai is careful, he still mentally despises the Xingtian Army, not to mention that now he has Shi Tingzhu and other Han barbarians under his command to help them fight, even if the Xingtian thieves are like what Dolgon Hauge said, the firearms are very sharp, and now they have a large number of firearms in the Han Eight Banners, firearms against firearms, plus their Jiannu archers and the brave and warlike Aliha Chaoha battalion (horse armor soldiers are also cavalry), there is no reason to lose to the Xingtian thieves again.

As long as the strength of the Xingtian thieves they bumped into this time did not exceed them too much, Abatai privately thought that they still had a great possibility to defeat them, think about if he led his troops into the customs this time and defeated the main force of the Xingtian thieves in the pass in one fell swoop, then he Abatai would be completely proud in the Qing Kingdom in the future, and he would no longer have to be inferior and always deceived because of his background!

But Abatai did not come to Shanhaiguan in person, personally experience the power of the firearms of the Dazhong Army, if Huang Taiji can let him enter the Shanhaiguan before sending him out, to actually watch the firepower of the Dazhong Army guarding the pass, it is estimated that Abatai will be more cautious, but unfortunately Huang Taiji has calculated everything, but did not include this point, it can be regarded as a hundred secrets, but Huang Taiji's one hundred secrets, but in the end, they Jiannu caused irreparable losses, made Huang Taiji regret it to death.

Although the defenders of Tongzhou under the command of Zhang Erzhong and Tang Tong and other civil and military officials, they fiercely resisted for two days, but Abatai, as an experienced veteran of the battlefield, still saw the weakness of the defenders.

Although the Ming army guarding Tongzhou does not seem to be too small, but the combat effectiveness of these Ming troops is far inferior to those Guanning troops outside the Guanzhou, whether it is equipment or morale, and even combat skills, there is a qualitative difference with those Guanning troops, although the first two days of fighting are also tenacious, but by the evening of the next day, Abatai and Haoge have already seen that these Ming troops guarding Tongzhou are already at the end of their strength, morale has fallen to the bottom, and resistance has become weak.

This reassured them, both of them believed that as long as there was one more day, concentrate their forces to launch a strong attack, they would be able to take Tongzhou, and when they took Tongzhou City, with the city gained, they could meet their demand for grain for many days, and then they could attack Shanhaiguan, give the Shanhaiguan defenders an internal and external attack, and take Shanhaiguan in one fell swoopHauge even thought that as long as this was done, the three Dolgon brothers would not be the challengers to his succession in the future, so both of them sharpened their knives and waited for the final blow to Tongzhou City on the third day.

But on the evening of the next day, Abatai and Hauge received bad news from the rangers who had been scattered, and in the vicinity of Tongzhou, after nightfall, suddenly an unknown number of enemy troops appeared, these enemy troops were unknown, but most of them were cavalry, and they acted in small forces, and began to make contact and fight with the Jiannu sentinels they scattered on the outskirts of Tongzhou.
