Entering Changchun Prefecture to rescue King Qin was Han Kuangsi's strategic goal, and as the first step to achieve this strategic goal, his soldiers pointed to Yongzhou, which Xiao Daxiang had just lost a few days ago. First, although the number of Zhou troops defending Yongzhou was small, considering that its strong combat effectiveness still posed a certain threat to its flank and rear, staying there was an unstable factor after all. Second, Yongzhou is located at the junction of the Tuhe River (Laoha River) and Huangshui (Xilamulun River), which is the necessary place for the Zhou army to transport grain and water. If they can retake Yongzhou, they can pose a serious threat to the Zhou army's grain route. Even if it can't force the Zhou army to retreat, it will at least distract it and even divide its troops to turn back and retake Yongzhou. In this way, it can not only reduce the pressure on the Changchun Prefecture side, but also buy time for the arrival of his own Qinwang army.

Therefore, when the pioneer officer Xiao Daxiang proposed to Han Kuangsi to take Yongzhou first and then go to Changchun Prefecture, the latter nodded and agreed after only a little consideration, and ordered King Qin's army to cross the Huang River and recapture Yongzhou as quickly as possible - even in Han Kuangsi's view, Xiao Daxiang's construction was not lacking in the elements of saving face for himself.

Linhuang City is only more than 200 miles away from Changning City in Yongzhou, and it is only two or three days away for the army of King Qinwang of Shangjing Dao, where almost everyone has horses. However, out of caution, Han Kuangsi did not move his army forward, but pulled the main force of the Chinese army away from the forward enough distance, and tens of thousands of troops formed a group and slowly moved forward. It was not until the morning of the fourth month of the lunar calendar in the nineteenth year of the Ying calendar (the seventh year of Jianlong) that Xiao Daxiang, the main general of the forward, sent the news that there were no Zhou army ambushes around Yongzhou City and that the city's defenses were relatively lax, and he led the army to arrive at the foot of Changning City.

Originally, according to Han Kuangsi's plan, he first surrounded Changning City, and then relied on his own military superiority to "attack the city in a hundred ways", and "drowned" the Zhou army defending the city with a sea of soldiers. To his surprise, although the Zhou army in Changning City was only 5,000, it did not use the city to make up for the disadvantage of its own troops, but went out of the city to line up, preparing to fight with the Liao army, which was ten times his number. Moreover, judging from the resolute, resolute, and fearless expressions on the faces of the soldiers of the Zhou army, the other side did not take the 50,000 Liao army in their eyes at all, as if they were full of confidence in defeating an enemy ten times their size. Although the warriors who are not afraid of death and treat the enemy like mustard are admirable, but the "arrogant" behavior of Zhou Jun who is so confident to the extreme, almost equivalent to asking for his own death, Han Kuangsi could not have the slightest admiration in his heart, but only sneered contemptuously. In addition, according to Xiao Daxiang's observation, the Zhou army that marched out of the city did not have the banner of "Flying Dragon Army", nor did it have the indestructible and formidable artillery during the Battle of Yongzhou a few days ago, which made Han Kuangsi more confident. So, taking advantage of the unfinished formation of the Zhou army and the unstable position, Han Kuangsi ordered the front army to immediately charge, in order to kill the Zhou army with one blow.

As the saying goes, "as soon as the expert stretches out his hand, he will know if there is one", as the Zhou army lined up according to the city, the 5,000 defenders withstood the fierce attack of the Liao army, not only were not crushed by the Liao army that surged up like a tide, but became more and more courageous the more they fought, and even fought many counter-attacks in local areas, giving a heavy blow to the offensive echelon of the Liao army with insufficient morale and weak fighting spirit. Seeing that his own soldiers would pull out and fall under the fire of the opponent's strong bows and crossbows, and lose nearly 2,000 people in just over an hour, Han Kuangsi couldn't help but be shocked in his heart, hurriedly put away his previous contempt, and ordered to stop the tactics of attacking the Zhou army's army formation from the front, and instead swept in front of the Zhou army's formation with some light horses, giving full play to his side's advantage of being good at cavalry and shooting, and using long-distance projection to fight. On the one hand, only the peripheral soldiers of the Zhou army were equipped with large shields, and the internal soldiers did not have the defects of this kind of anti-arrow equipment, so the Zhou army was killed to a certain extent. On the other hand, it was to consume the arrows of the Zhou army and prepare for the subsequent attack.

After tactical adjustments, the Liao army not only quickly reduced the number of casualties, but also as the soldiers in the Zhou army continued to fall from arrows, the morale of the Liao army, which had been reduced due to the ineffective attack, was gradually restored, and the momentum of the Zhou army was eaten up in one go.

Seeing that his morale was getting higher and higher, while the morale of the Zhou army was gradually declining, and the arrows fired from the Zhou army's array to his rangers were becoming more and more sparse, Han Kuangsi realized that his opportunity had come. Therefore, he immediately ordered the 10,000 horses and horses of the front army to press, and crushed the Zhou army in one blow and took Changning City.

Maybe it was the previous state of almost being beaten that made the soldiers demoralized, maybe it was the morning of fierce fighting that made them exhausted, or maybe Han Kuangsi's attrition tactics were effective, in short, in the face of the all-out blow of the Liao army's front army, the Zhou army defending the city finally couldn't resist the enemy, and the position began to loosen. As more and more soldiers and horses of the Liao army joined the attack, the Zhou army, which suffered more and more losses, finally could no longer maintain the integrity and solidity of the formation, and gradually moved and contracted in the direction of the city gate, and even showed some signs of collapse.

Just when Han Kuangsi thought that the victory was in his hands and was about to hit the army, a team of about two hundred people suddenly appeared at the head of Changning City behind the Zhou army's military formation. Without waiting for Han Kuangsi and other high-ranking generals of the Liao army to see his banner clearly, they had already entered the battle, and in a roar as fast as bursting beans, they poured a wave of bullets and retreated to the Liao soldiers who were slaughtering the Zhou army's army array, and swept them down in pieces like wheat harvesting. This sudden blow not only suffocated the Liao army's attack, but also gave the Zhou army, which was struggling to support, a chance to breathe, and took advantage of the situation to launch a counterattack, killing the Liao army back again and again, and restoring the formation that had been compressed very badly before.

In the face of this sudden appearance of the Zhou army, which was equipped with firearms, both Han Kuangsi and other generals of the Liao army were a little caught off guard. In the case that the number of firearms troops on the other side could not be determined for a while, in order to avoid unnecessary losses, Han Kuangsi hurriedly ordered to stop the attack and shrink the formation, and on the other hand, he secretly complained in his heart that Xiao Daxiang had made a mistake in his investigation, and failed to find that this Zhou army was obviously from the "Flying Dragon Army" equipped with powerful firearms. However, to Han Kuangsi's slight reassurance, after the Zhou army took advantage of firearms to kill the Liao army, it did not take advantage of the victory to chase after it, but slowly retreated and collected troops back to the city after driving the Liao army away from the city wall for a certain distance.

Seeing that the Zhou army did not catch up, Han Kuangsi, who was relieved, ordered the army to restore the formation and stabilize the formation, and sent people to find Xiao Daxiang, intending to "communicate" with him on the issue of untruthfulness. As a result, before he could open his mouth to reprimand Xiao Daxiang, who came to him, a scout came to report, saying that after the Zhou army retreated into the city, he did not go to the city to defend, but directly passed through the city, opened the east gate of Changning City and fled in the direction of Guangpingdian.

Zhou Jun fled? That's impossible! -- This was the first reaction of Han Kuangsi and other Liao generals after receiving the news. Because, on the one hand, in their opinion, since the defenders of the Zhou army in the city have the help of the "Flying Dragon Army", there is no need to abandon the city and leave. On the other hand, they really couldn't understand why the Zhou army had the intention of escaping, why they risked the possibility of annihilation to go out of the city to fight the Liao army face to face, and paid nearly 2,000 casualties for this. Even in order to avoid the crime of failing to defend the city and escaping from the battle, the Zhou army defenders can also send a small number of people to defend the city against the enemy, and make a desperate appearance of defending the city, and then take advantage of the Liao army to completely surround Changning City before the main force abandons the city and flees, and does the plan of abandoning the army to protect the commander and the golden cicada to get out of the shell. In this way, most of the strength is preserved, and it can avoid the inquiry of the peak, so why not do it.

Just when Han Kuangsi and other Liao generals were puzzled, Xiao Daxiang brought them the answer - according to several Zhou prisoners who failed to escape from Changning City in time due to injuries, although Changning City is located at the junction of the Tuhe River (Laoha River) and the Huang River (Xilamulun River), and its geographical location is relatively important, it is not indispensable for the Zhou army, which mainly relies on waterways to transport grain and grass and military baggage, and believes that the naval army responsible for its escort is fully capable of protecting the safety of the grain and grass army's baggage fleet. Therefore, the order given by the commander of the Zhou army to the guards of Changning was to ensure that all the grain and grass troops stored here were safely on the ship, and only to delay the Liao army that might counterattack Yongzhou, and once they felt that Changning City could not be defended, they would quickly retreat, so as not to suffer the loss of Yanzhòng, but they did not defend Changning and did not retreat for half a step. The reason why the Zhou army had put on a desperate posture with the Liao army was entirely because before the Liao army came, the last batch of grain and grass army had just left the city for a long time, and according to the time, it should not have arrived on the river bank to load the ship. Therefore, in order to ensure the smooth transportation of this batch of baggage, the Zhou army guards had to use the formation outside the city to attract the attention of the Liao army with a posture of fighting to the death, so as to protect the safety of the baggage.

As for not pulling out the "Flying Dragon Army" at the beginning, on the one hand, the "Flying Dragon Army" that stayed in Changning had a limited number of troops, less than 200 people--this is probably the main reason why Xiao Daxiang failed to discover its existence when he investigated before. On the other hand, they were afraid that they would use the "Flying Dragon Army" to make the Liao army fearful, so they changed the attack to besiege the city, cutting off their own retreat. Therefore, it was not until they got the news that the grain and grass had been loaded onto the ship and anchored to the east, that the Zhou army guards offered the "Flying Dragon Army" to stun the Liao army, and took advantage of the Liao army's momentary confusion and confusion to withdraw from the battlefield and abandon the city.

Knowing the "ins and outs" of the matter, Han Kuangsi couldn't help but sigh, secretly annoyed that he had fallen into the hands of the Zhou army, and turned a big victory that could completely annihilate 5,000 Zhou troops and achieve the greatest results between the Liao army and the Zhou army since the sixth year of Xiande into a small victory that only defeated the Zhou army by destroying more than 2,000 enemies. However, there is no "regret medicine" to take in this world. The matter has come to this point, no matter how annoyed Han Kuangsi is, he can only accept this reality. But the problem is that Han Kuangsi can accept reality, but it doesn't mean that others can also accept reality. In particular, Xiao Daxiang, the vanguard officer who failed to find the existence of the "Flying Dragon Army" in the city, was even more indignant at the escape of the Zhou army, and repeatedly asked Han Kuangsi for orders, hoping to agree to allow him to lead his headquarters to pursue the Zhou army and annihilate it.

Although he thought that it was unnecessary to pursue the fleeing enemy for the sake of face, he couldn't stand Xiao Daxiang's hard work, and even swore a curse, saying that he would never come back to see the commander until he completely annihilated the Zhou army. Second, considering that there are many lakes in Guangpingdian, dense forests, swamps, and sand moraines, fighting there is very beneficial to the Liao army who are familiar with the terrain there. Therefore, in the end, Han Kuangsi, who was so annoyed that he had no choice, had to reluctantly agree to Xiao Daxiang's request and allow him to lead his headquarters to pursue the fleeing Zhou army. However, for the sake of safety, while allowing Xiao Daxiang to pursue the enemy, Han Kuangsi also instructed him to "chase after the poor army", and whether or not he caught up with or annihilated the Zhou army after dark, he must stop the pursuit and return to the camp. In this regard, Xiao Daxiang naturally agreed, and happily led 5,000 soldiers and horses from his headquarters to rush out of Changning City and kill them in the direction of Guangpingdian.
