Cao Yue and Sun Chuanting at the head of the city both discovered the Jiannu cavalry attacking from the flank, and they had been prepared for this, so they immediately ordered the musketeers of the second battalion to enter the back of the car formation and prepare to shoot.

Half of the Spark Battalion of the Third Battalion also drove out of the city, ready to join the battle group, and the pikebattalion on standby also rushed out of the West Gate and prepared for battle.

Cao Yue continued to mobilize troops from several other gates, preparing to go out of the city to respond. At the same time, he also asked Wei Daben and other officials of Datong Mansion to urgently mobilize the young and middle-aged people among the people, preparing to let the young and strong people join the army defending the city.

One thing that made Cao Yue feel at ease was that in Datong City today, gunpowder and food are quite sufficient, according to the current situation, food can last for several months, and the ammunition can be used for at least one day with the uninterrupted use of two and a half musket battalions.

The amount of usage in one day may not seem like much, but the actual amount is quite a lot. One day the musket continued to shoot, the amount of consumption was very amazing, to Cao Yue's thoughts, if the fire was not stopped, the gunpowder was not consumed, and the musket had been scrapped.

If this is the case, it can only make the musketeers turn into infantry, and use the broadswords on their waists to fight Jiannu.

The battle outside the city became more and more intense, and in the direction of the frontal position, the attacking Jiannu did not retreat because of the huge casualties, they stepped on the corpses of their comrades, and attacked wave after wave. But unfortunately, their attack was still in vain, and the soldiers of the 1st Musket Battalion used the muskets in their hands to build an impassable line of death, and few Jiannu soldiers could rush within the range of their bows and arrows.

The arrows fired by the few sergeants who were lucky enough to rush within the range of the bow and arrow did not pose much of a threat to the Datong army.

The more than 200 mercenaries led by Constance were not sent out of the city by Cao Yue this time, and they stayed by Cao Yue's side as a mobile force.

This made Justin very dissatisfied, thinking that this was belittling their combat effectiveness, but he couldn't help it, and finally obeyed Cao Yue's arrangement.

On the position outside the city, at the front was a large number of carts to form a chariot formation to block the attack of the Jiannu cavalry.

In front of the chariot array, there were also a large number of rejecting horses, as well as some gadgets that were very effective against cavalry, such as three-legged iron developed by Cao Yue. Even if the shooting of the musket battalion could not completely stop Jiannu's attack, Jiannu would have to pay a lot of price if he wanted to rush to the position of the musket battalion.

The outflanking of the two flanks of Jiannu was very fast, but just as they rushed to kill, the position of the Datong army changed again.

The cavalry, who had been on horseback and on standby, quickly got out of the way and approached in the direction of the same city.

Where they got out of the way, a large number of muskets were mounted on the cart formation, and the musketeers of the second and third battalions were ready to start the battle. But the Jiannu who came quickly did not discover this situation in time, they thought that the cavalry of the Datong Army, like the previous Ming army, began to be afraid and evacuated their positions in the face of the fierce impact of the Qing army.

In the north direction, he led the army to attack Chebai, which was in the forefront, and rushed to the front of the front, preparing to rush to the front of the Ming army at the fastest speed, disrupting the Ming army's musket array, and then massacring it on a large scale.

Chebai is a fierce general, people who are familiar with the late Ming and early Qing dynasties know this character, and later almost mastered the important court of the Manchu Qing Dynasty, and was finally destroyed by Kangxi. At this time, the status of chelation was not very high, far lower than Dorgon, Dordor, Hauge and others. However, Chebai is very brave in battle, his strength is very great, and his martial arts are also outstanding, and ordinary people are not his opponents.

Chebai's own soldiers are also brave men. He believed that as long as he rushed into the Ming army's formation, he would definitely be able to kill the Ming army.

But just when Chebai was about to rush to the front of the Ming army, suddenly from the Ming army in this direction, a burst of black smoke came out, and in the black smoke, a row of musket bullets flew towards Chebai and the sergeants under his command who rushed to kill.

Chebai also reacted very quickly, and immediately turned sideways and hid on the side of the war horse, so that he was lucky enough to avoid the bullet shooting, but his war horse was hit by a row of scattered bullets, and immediately messed up the pace of the impact and jumped up.

Seeing that the situation was not good, Che Bai immediately jumped off the war horse, grabbed another war horse that was shot off the horse, and continued to charge forward.

The pro-soldiers around Chebai were knocked over several people, and their impact speed suddenly slowed down. Unexpectedly, there were also Ming musketeers in this direction, and they suddenly didn't dare to be careless, nor did they dare to rush to kill recklessly, so they couldn't help slowing down. At this time, the other Jurchen cavalry who came at high speed had already crossed the position of Chebai and rushed forward, and Chebai was very lucky, someone blocked the musket bullets for him.

In the south direction, there were men and horses commanded by Azig, but Azig was not as impulsive as Chebai, and the few Jurchen elite cavalry rushed to the front, but ordered the Mongol soldiers of Zhu Xili, as well as the Han troops of Kong Youde and Shang Kexi, to rush and kill at the front.

They were also greeted by ammunition from the Datong Army Musket Battalion, and before they could rush to the Musket Battalion position, they fell in large numbers. However, the Mongol and Han soldiers did not flinch, but stepped on the corpses of their comrades and continued to charge.

In the frontal direction, the first to rush to kill, Sonambu has suffered extremely heavy losses, nearly 20,000 Mongol soldiers, at least 10,000 people fell in front of the Ming army's musket array, and many others were trampled to death by their companions and friendly troops.

Sonamu, who had never experienced this kind of warfare, had been dominated by grief and anger, and his strong revenge mentality made him lose his mind, and he repeatedly ordered his men and horses to rush to the Ming army no matter what, to avenge the dead clansmen.

Sonamu himself was wounded, and when he saw that the charge was defeated again, and countless Mongol warriors were killed by the artillery and muskets of the Ming army before they could shoot the arrows of revenge, he vomited blood in grief. "Baturu, follow this king, kill, kill all the Nanming barbarians," Sonamu wiped the blood from the corner of his mouth, held his sword high, and shouted at the soldiers on his side and those soldiers who had finally retreated, "Follow this king, kill all the Nanming barbarians." Anyone who dares to retreat will be killed!"

In the shouting, Sonamu had already urged the mounts under him, and rushed towards the Ming army, which was no longer clear in the smoke of gunpowder in front of him.

In the early morning, there was a wind outside Datong, but the wind blew quickly and occasionally.

After the musket and artillery are fired, a large amount of black smoke is produced, which affects the vision of both sides. However, the Ming army, which was shooting non-stop, took the same angle of fire and shot in the same direction, and the Jiannu who wanted to break through the Ming army's musket array basically came from the same direction, which can show that even if the soldiers and soldiers hit with their eyes closed, they could basically hit the Jiannu who was not far away.

However, after Jiannu piled up a large number of corpses in front of the battle, he had to change the route to attack.

Fortunately, a gust of wind blew from time to time, temporarily blowing away the black smoke, which allowed Cao Jie and others, who commanded the operation, to discover the situation in time.

Cao Yue, who commanded the castle, used binoculars and a position far higher than the outside of the city to see Jiannu's attack more clearly and convey the situation to the commanders outside the city.

Sonamu personally led the charge of the army, which changed the direction of the attack, but the direction of the impact of his men and horses was quickly transmitted to Cao Jiehe, and Cao Jie immediately adjusted the angle of shooting.

In a violent roar, Sonamu and his most elite soldiers fell in rows under the muskets of the Ming army.

A flowering bullet fired from the top of the city landed right next to Sonamu's horse, and Sonamu, along with his beloved horse, was blown into the air and turned into a pile of stumps and broken arms!
