The 5,000 sergeants of the first battalion, escorted by the two wings of the cavalry led by Zhao Tai, the deputy commander-in-chief, quickly lined up outside the north gate of Datong.

After this period of rigorous training, the officers and men of the first battalion have greatly improved their organizational discipline, and they have basically achieved the relaxation of orders and prohibitions, and their overall ability to cooperate and coordinate is not comparable with that of ordinary armies. The soldiers of the first battalion were all equipped with muskets that had been improved by Cao Yue, and the firing range was longer. They can be said to be fully clothed, with grenades and daggers in close combat.

After personally inspecting the training results of the first battalion, Cao Yue could say with great confidence that the first battalion is now the "first army in the world."

This battle will be the famous battle of the first battalion, Jiannu's men and horses are less than 10,000 people, and they are ready to launch an active attack, Cao Yue believes that as long as Jiannu dares to keep charging, at most an hour later, Datong City will become a slaughterhouse.

These nearly 10,000 horses will be the target of the first battalion.

The Jiannu who attacked the city of Datong were all cavalry, and the soldiers who watched the battle at the head of the city waited in fear, and they set up their positions and prepared to attack. Under Geng Zhongming's personal order, the first wave of 2,000 people had already been set up.

With the order of the commander of the former army, the two thousand people urged the war horses and began to attack.

Because there is ice and snow everywhere, in order for the war horse to slip and fall, whether it is the Jiannu army or the Ming cavalry, they all tie non-slip cloth strips or other objects on the hooves of the war horse, but even so, it also affects the travel speed of the war horse, charging in the ice and snow, the speed is definitely not as fast as usual. Cao Yue also thought of this, so he was full of confidence in today's victory.

The speed of the horse's impact is slowed down, and the musketeers have a better chance of firing one or two more rounds of ammunition, and one or two rounds of muskets can be quite lethal.

In the field of vision, Jiannu's cavalry began to accelerate, and Cao Yue personally gave the order for artillery fire.

With Cao Yue's order, dozens of various artillery pieces placed on the head of the city were fired in a certain order.

As the deafening sound sounded, in the clouds of black smoke, flowering bullets and solid lead bullets fell towards Jiannu's stormtrooper one after another. The explosion of the flowering bomb "rumbled", and some of the hapless Jiannu were blown into the air along with their horses. Where the solid bullet slid quickly, the Jiannu who collided head-on turned into flesh and mud in the screams, and the solid and hard bullet ploughed open a bloody "passage".

Jiannu had long expected that the Ming artillery on the city would bombard, so the formation of their charge was kept very sparse, and the distance between the sergeants and sergeants was relatively long, so as to minimize the losses caused by the artillery bombardment, after all, the density of artillery fire is not high today. When they rush in front of the enemy array, they gather a little more, so that they can re-form a dense formation and inflict great damage on the opponent.

After a round of artillery fire, the Ming army in charge of the artillery whistle at the head of the city was scrambling to clean the barrel, cool the barrel, and prepare to fire again.

Taking advantage of the gap between the artillery fires, the ranks of Jiannu began to gather, and their speed began to increase.

Originally, the place where the slaves were lined up was only two or three miles away from Datong City, and the cavalry's impact speed was not slow, and before the second round of artillery could be fired, they had already rushed to a place less than a mile away from the position of the first battalion.

"First team, prepare!" Cao Jie, who was quite nervous, shouted out the order in a trembling voice.

This was the first time he had commanded his men and horses to fight against the enemy alone, but fortunately, Cao Yue was at the head of the city behind him, giving him confidence. But he was still very nervous, and there was sweat on his forehead in the cold weather.

Today's muskets have a range of about 100 to 150 paces, about 150 to 200 meters. This distance is far better than bows and arrows, and also more than ordinary crossbows, which is the advantage of firearms, and it is also the main reason why Cao Yue believes that although firearms are not advanced, they are still better than bows and arrows.

Soon, the centaurs of Jiannu's first wave of attacks were about to enter the range of the muskets, and Cao Jie used all his strength to shout the order to "shoot".

With Cao Jie's order, a puff of black smoke rose from the Ming army's array, and almost at the same time, a deafening explosion of gunpowder sounded. The first team of 1,000 sergeants, after Cao Jie's order was given, fired the ammunition in the chamber of the gun almost at the same time.

After firing, they retreated very decisively to the end, and then the sergeant of the second team stepped forward with muskets in hand and raised his guns to aim.

Nearly half of the more than 1,000 sergeants in the first team had followed Cao Yue to participate in the sneak attack on Shengjing, and their psychological quality was far better than that of ordinary sergeants, and their shooting skills were also better.

With the shooting of the first team of sergeants, the fast-running Jiannu cavalry suddenly fell a large piece, and the screams of countless tragedies and the sorrowful roars of the war horses resounded under the city of Datong, and the bright red blood was mixed with the ice, snow and sludge under the feet, and it was a mess.

"Second team, shoot!" Cao Jie's order roared again, and this time his voice was no longer trembling, but extremely high-pitched.

The death and bloodshed of the enemy gave the soldiers a great thrill, and strongly stimulated their animal nature, and there was nothing more exciting than harvesting the death of the enemy from a distance with the musket in his hand.

"Third team, shoot!"

"Fourth team, shoot!"

"Fifth team, shoot!"

"First team, shoot!"

“”

Cao Jie's voice quickly became hoarse, because he inhaled too much black smoke, he couldn't help coughing violently, and his tears and snot were choked out. However, he did not feel any sadness, and his heart was full of great excitement.

After three rounds of fifteen batches of musket firing, the four rounds of Jiannu's charge were all disintegrated, and at least 5,000 Jiannu and their war horses fell about 50 to 100 steps away from the position of the first battalion, losing their combat effectiveness, and nearly half of the Jiannu who fell to the ground will always lose the opportunity to continue the battle, and their lives cannot be continued after today.

Such a result made Cao Jie stunned and excited.

Cao Yue, who was at the head of the city, saw all this completely through the thick smoke and a telescope, and such a result was not much of a surprise to him. Although the arquebus is backward, in such cold weather, the failure rate is lower than that of the flintlock pistol, as long as the firearm does not malfunction and the arquebus can ignite, the shooting can be successful. The dense queue of 1,000 sergeants per team fired nearly a thousand rounds of ammunition, giving Jiannu no less damage, and the musket firing was almost non-stop, although Jiannu's cavalry attacks were continuous, but the non-stop musket shooting did not give Jiannu a chance at all, and they could not even rush into the range of bows and arrows.

Seeing that the attack of Jiannu was completely disintegrated, and there was no more organized Jiannu cavalry rushing in, Cao Yue at the head of the city gave the order to encircle and annihilate very decisively. With Cao Yue's order, the cavalry that was originally guarding the two wings of the first battalion, under the command of Zhao Tai, bypassed the battlefield full of dead and wounded and killed the remnants of Jiannu.

The other generals who were on standby at all gates, after hearing the horn of the charge, also rushed out of the city gate and killed the remnants of Jiannu.
