After the first round of gunfire from Jiannu's artillery, the roar temporarily stopped.

Although the red coat cannon is relatively advanced, it is still a shortcoming due to the inability to shoot continuously, clean the barrel, and wait for the cooling before firing the second round. In the first round of firing, two shells hit the city, causing casualties among dozens of defenders.

Cao Yue didn't expect that Jiannu's red-clothed cannon had such a long range, and he could actually open the city, and when he saw that some soldiers appeared to be killed and injured under the fire of artillery, he immediately ordered the soldiers to be prepared and hidden. Jiannu's artillery cannot fire continuously, and when its artillery fires again, it can lie down to dodge, or spread out, and wait for the artillery to fire over, and then return to its original formation.

The first round of artillery fire at the head of the city did not hit the artillery position of Jiannu, and it exploded at a distance of about a few hundred meters in front of its artillery position, killing a bunch of sergeants of Jiannu guarding the artillery, which can be regarded as a result of a mistake. Cao Yue also immediately ordered the artillery commander to correct the angle and direction of the fire, and prepare for another round of firing, striving to hit his artillery position and destroy part of Jiannu's red-coated artillery.

"Woo woo woo ......", outside the city, the low horn sound sounded one after another, and the fierce war drums were also beating fiercely, accompanied by the sound of horns and war drums, a team of Jiannu began to move, slowly and orderly towards the direction of Datong City.

Jiannu began to attack from the north gate and the west gate at the same time, and the two siege Jiannu lineups were very large, according to Cao Yue's estimates, each team had at least more than 20,000 people.

The sun is shining, all kinds of flags are waving in the wind in the sun, spears and swords are shining with the light of death in the sun, which is very dazzling, and endless killing machines are rolling towards Datong City.

At the forefront were still the Eight Banners of the Han Army, and the Korean Army with some servants, followed by the Eight Banners of Mongolia, and then the Eight Banners of the Jurchens.

The Jiannu who attacked in both directions were finally suppressed by the Jurchen cavalry, they were the last wave of attacking force, and they were also the overseers on the battlefield, if the Han army, the Korean army or the Mongol Eight Banners in front of them were in confusion, or they did not retreat and fled, they would pick up their swords and slash at the defeated to prevent them from escaping.

"Kill......" In the direction of the north gate, the 3,000 Han troops and 2,000 Korean troops who rushed to the front rushed out of the array of the Jiannu army, many sergeants raised the ladder, and more sergeants brandished their swords and howled to kill Datong City. This time, Jiannu's attack was not reckless, and at the forefront were the shield soldiers, each carrying a large shield, followed by the crossbow archers and archers with the strongest arm strength behind the shield soldiers.

The shield on the shoulders of the shield soldiers is the most effective weapon to defend against the musket shooting of the Ming army, the shield is three or four inches thick, and the surface is also covered with iron sheet and several layers of cowhide, the musket of the Ming army can easily penetrate the armor on Jiannu's body, but it cannot shoot through such a strong shield. Jiannu's tactic was to use the shield as a cover, and after rushing to the city, he used his skillful shooting skills to shoot the defenders on the city with bows and arrows.

Although the power of the musket is far greater than that of an arrow and the range is longer, the direction of the bullet flight is basically a straight line, and when it loses kinetic energy and falls, the lethality is already negligible. But arrows are different, no matter what kind of arrow, you can draw an arc. Jiannu, who is hiding behind the oar, can use the arc of the arrow's flight to shoot at the castle by hiding behind the oar.

As they were about to enter the range of the Ming army's muskets, the shield soldiers held their shields high to cover themselves and the sergeants behind them.

At this time, Cao Yue, who was at the head of the city, gave an order for artillery fire.

In the direction of the north gate, nearly 100 large-caliber guns and Franc machine guns opened fire almost simultaneously, and solid shells and flowering shells flew from the barrels of the guns at high speed to the array of siege and construction slaves in the roaring cannons. More than a dozen solid iron bullets weighing dozens of pounds plowed out more than a dozen bloody paths of Jiannu's shield array, and the flowering bullets blew one side of the shield into pieces. The neat shield wall was about to crumble, and at this time, the first round of musket fire began on the city. With the roar of the muskets, the surviving Jiannu, who had lost the protection of the shield, became the target of the guns and fell in rows.

The roar of the artillery stopped, but the fire of the muskets continued, and the second and third rounds of musket fire continued, and row after row of Jiannu fell under the fire of the muskets. Subsequently, the artillery began firing again.

After two rounds of artillery and five rounds of musket fire, nearly half of the 5,000 Han and Korean troops who attacked in the first round fell under the artillery, muskets and bombardment, and were either killed or wounded.

The morale of the Han army and the Korean army was already low, and seeing such large casualties, their companions fell in rows, and the remaining Jiannu no longer had the courage to attack, and many people threw down their heavy slurs and sabers in their hands and fled. Escaping was like a plague, and immediately spread, and no longer rushed forward in the face of the fire of muskets, they all fled backwards in a swarm, only hating their father and mother for giving birth to two legs for themselves.

At this time, the red-coated cannons at the head of the city were silent for a while, and then they began to shoot again, and one after another flowering shells flew towards Jiannu's artillery position. Luckily, a cannonball landed next to one of Jiannu's red-clothed guns, and the blast caused the cannon to overturn the cannon, and the sergeant who was operating the cannon was blown into the air. Ammunition in the vicinity of the artillery was ignited, which led to a series of explosions.

Fortunately, each cannon was not far apart, and the explosion of the most distant cannon did not cause a chain reaction.

But the red-coated artillery of the Ming army fired again before them, and the accuracy was so high, it still surprised the traitor Tong Yangxing, who commanded the artillery battalion. He immediately ordered the rest of the artillery to return fire with all his might.

With a huge roar, Jiannu's artillery position began to shake and tremble, and in the midst of countless clouds of black smoke, the flaming shells flew at high speed in the direction of the north gate of Datong.

Two shells grazed the city wall and flew into the city of Datong, and after the explosion, a group of Ming soldiers on standby under the city were blown into the air, wailing again and again. A cannonball landed on the outside of the city wall, and the enormous force of the explosion blew up a pile of broken bricks, and overturned several Ming musketeers who were about to shoot at the head of the city outside the city.

Several shells landed in the moat, stirring up sparks that rushed into the sky, pouring sewage on the faces of the Ming soldiers in the nearby city.

At this time, after killing a number of deserters, the Han and Korean armies, as well as the Mongol Eight Banners, began a larger second round of charge.

Thousands of Jiannu, holding high shields, carrying ladders, and brandishing swords, quickly killed in the direction of the north gate of Datong under the orders of their respective supervisors. In the smoke of gunpowder, there were waving battle flags everywhere, and there were swords shining with the light of death!
