When Zhang Jiayu's Dragon Guards approached about a mile and a half away from the enemy, the cannons on the flanks took the lead in roaring.

Suddenly, ten iron balls smashed into the mud wall of the Qing army's temporary foundation with a sharp whistling sound of breaking through the air.

Even the most powerful six-pounder cannon shook the two-foot-thick wall, leaving a spider's web of cracks.

The nine-pounder cannon and the twelve-pounder cannon tore a huge gap directly in the earthen wall, and under the dust, clods of soil and gravel burst out in all directions, and the Qing army hiding behind immediately howled wolf, and more than a dozen people covered their faces with blood and rolled to the ground.

The loading speed of the Ming artillery was even faster, and Sinebku held the telescope before he could find the location of the cannon on the opposite side, and the second round of shells had already hit again, and the defense line of Jianyu was immediately screaming again.

It wasn't until the third time that the Long Wei Army opened fire that his adjutant finally found the artillery position of the Ming army and hurriedly pointed it out to him.

"Damn, do you think Lao Tzu didn't have a cannon?!" Sinebku sneered and yelled at the herald, "Bombard those barbarian cannons with all my might!" ”

He was not too worried about the artillery of the Ming army, with the cover of the earthen wall, the artillery on his side would not be injured by the artillery fire on the opposite side at all. However, the guns of the southerners were all placed in the wilderness, and the shells on their side could soon force the Ming gunners to dodge in all directions.

"Huh!"

As the herald officer left, the eleven cannons behind the Jianyu line immediately began to return fire. But to their surprise, the Ming artillery in the distance actually set up a cart and was dragged by horses and quickly advanced more than 100 paces, so that all their shells missed.

The gunners of Sinebku hurriedly lowered the muzzle and reloaded, during which the Ming artillery fired two more bombardments.

When the Qing army finally completed aiming, the cannon on the opposite side shifted again, like a loach that couldn't slip through the hand.

The deputy company commander of the Ming artillery company put away the binoculars, turned back to Kong Liangcheng and saluted: "My lord, there are eleven cannons of the captives, scattered all over the back of the earthen wall, there, there, and there......"

"That's a lot of guns." The latter looked at the earthen wall and frowned, "Pull up the mortar!" Even if you miss, you can scare and scare the Tartars. ”

"Yes!"

Soon, six horses dragged thirty-two-pounder mortars to the artillery position. This kind of curved artillery is difficult to aim in positional warfare, and the artillery company on Huanglongbu's side has limited manpower, so Kong Liangcheng, the commander of the company, did not plan to use it at first.

The gunner of a nine-pounder gun then switched to operating the mortar. The two soldiers in charge of aiming lay on the ground, holding bamboo pens and began to calculate. They were the best of the last class of artillery graduates of the New Army Academy, and they had learned to apply the equations left by Zhu Linwei and substitute various parameters to calculate simple ballistics.

In a moment, the two of them completed the calculation, and loudly reported the shooting of Zhu Yuan, "The elevation angle is six and a half minutes, the direction is due north and west for two minutes, and the charge is seventy." ”

The other gunners skillfully loaded their ammunition and adjusted the angle of the cannon. With a loud bang, a huge iron ball of thirty catties flew out of the barrel, drew a semicircular arc in the air, bypassed the earthen wall of the building, and smashed down twenty steps to the left of the two nine-pounder guns.

The ground shook as if there had been a small earthquake. Sinabuku, who was still as steady as Mount Tai, looked at the millstone-sized crater more than ten zhang in front of him, his eyelids jumped suddenly, and he hurriedly circled his horse and ran for more than half a mile into the distance before stopping.

The cannon of Jianyu was limited by the old gun carriage, but it could not be moved at all for a while.

The gunners on the Ming side observed the landing point of the shell in the telescope, immediately adjusted the angle slightly, and then reloaded again.

The mortar spewed out fury again, and the shells flew over the Jianyu earthen wall, and fell close to the two nine-pounder cannons of the Qing army, although they did not directly hit the cannons, but smashed the two gunners on the side into flesh, and the earth that shot out of the fire seriously injured four people.

The rest of the dozen or so gunners looked at each other, where did they dare to continue firing? At that moment, he let out an exclamation and fled in all directions.

"Good fight!" Kong Liangcheng saw clearly in the telescope, and then pointed to another Qing army cannon, and said to the mortar gunner, "Change the two ...... on the west side."

In the process of the mortar artillery to clear the Jianyu cannon, the Ming artillery company carried out another sixteen or seventeen rounds of salvo fire, and the dense shells bombarded the mile-long earthen wall of Jianyu into gaps, like an old lady with open teeth.

At the same time, the infantry line of the Dragon Guard Army was also approaching one hundred and seventy or eighty steps from Jianyu, and Li Ying ordered in a loud voice, "Organize the queue and move forward slowly!" ”

As several flares were raised, thousands of Ming soldiers repeated the military order in unison, "Sort out the queue and move slowly!" The infantry line, which was more than two miles long, lined up quickly to the left and right, and then continued to press the enemy position in small steps. The main purpose of this approach is to keep the queue as neat as possible.

Sinabku stared at the approaching Ming army behind the battle formation, and a serious flash of resentment flashed, "Damn, don't you just know how to use cannons, what's the big deal?!" Wait for you to take a few more steps forward, and discipline you to taste the flintlock of the yellow flag! ”

After Dorgon purchased steel from Japan to make springs, the flintlock guns of the "cottages" were finally put into use.

As the elite of the Qing army, the Manchurian Zhenghuang Banner Department was the first to be equipped with this kind of firearm. And in the hands of the 3,000 Yellow Banner Guards in the hands of Sinebku, there are more than 2,000 flintlocks.

He had seen the power of this gun many times before—the rate of fire was high, the soldiers could be closely aligned, and the power of the eleven penny bullet was even more amazing.

He was full of confidence, with such a powerful firebolt, plus the cover of the earthen wall, if the southern army dared to rush up, it would be no different from sending him to death.

Prince Yu only ordered me to stay until noon, and Sinabku sneered in his heart, if I defeat this group of southerners, His Royal Highness will definitely praise my bravery......

When he was "exalting himself", the Ming army had reached about 110 steps away from the earthen wall, but suddenly stopped.

"What is this for?" Sinabuku was stunned, and then suddenly realized that the southerners were deceiving me. At such a distance, where is the head of the firecracker, the southerners must want to take advantage of the gap between the reloading of our army's guns!

He hurriedly said to the herald beside him: "Order, wait until the enemy is close to seventy paces before fighting, and those who violate the order will be killed!" ”

"Huh!"

Some of the officers who had built the captives had already planned to give the order to open fire, and they were ordered to immediately shout to the soldiers not to move, but they were shocked to hear the earth-shattering unison from the Ming army position opposite, "Aim!" ”

"Put!"

The Dragon Guard Army and the Broken Prisoner Battalion have now all been equipped with rifled guns, and in an instant, the more than two miles long Ming infantry line shines with starry fire, and thousands of Mini bullets are like the life talisman of the Hades, instantly enveloping the entire Jianyu defense line.
