The cannon is an eighteen-pound mortar cannon that accompanied the troops, and the barrel of this cannon is extruded from a steel pipe, and the weight without the base is less than 40 kilograms, which is nearly half of its prototype 24-pound caliber M1852 mortar. Yesterday, it was it that made Jiannu realize what bloody rain is.

And now, in the face of Jiannu's cavalry onslaught, Chen Wushu has also prepared a feast for them!

A feast of iron and fire!

Compared with the field artillery, the advantage of the eighteen-pound mortar gun is that it is easy to shoot, the gun is placed on the flat ground, and the recoil will be transmitted to the base plate through the short and thick lugs located at the tail of the barrel, but the simple structure will also bring inconvenience, because there is no gun wheel, if you want to change the direction of the gun or move the position, you must rely on the strong gunners to lift it.

However, these are not worth mentioning compared to its advantages, its rate of fire is fast enough, not only is it light enough to march with troops, but more importantly, its ballistic curve can bombard enemy troops from hollow formations. Just like now, and this is exactly what flat-firing field guns do not have.

With Chen Wudi's order, the gunners who had been marching with cannons for a long time finally made moves, and they moved extremely quickly after enduring a long time, but they were ready after only a few breaths. Although it is not easy to accurately hit a target with a mortar, it is difficult for even a seasoned artilleryman to do so. But they can still get the shells to the right distance accurately.

They had already aimed at the front, and all they needed was to wait for the enemy to reach the "trap". With an order, dozens of mortars fired dozens of grenades at the wings, and although its accuracy was not high, a larger caliber meant more charge, which to some extent compensated for the lack of accuracy.

"Ming Dog ......"

Almost when dozens of flames erupted from the Ming army's array, Abatai scolded so secretly in his heart, he even admired the Ming army generals for a while, he could really endure it, and he couldn't fire until he rushed into battle!

"Hiss......" eighteen-pound grenade dragged a somewhat dull breathing sound, flying from the ground to the sky, although the battlefield echoed with deafening shouts and horses' hooves, everyone clearly heard its whistling, his whistling sound was dull, several pounds of gunpowder made the heavy cannonball can fly out at an initial velocity of more than 200 meters, it dragged the white smoke in mid-air and slid out of a curved arc, and then smashed into the galloping and constantly expanding the horses, a charging Qing cavalry was running, the head and the iron ball collided, It smashed like a watermelon, and then it jumped in the air, albeit slowly, still splashing several blood mists in the caravan.

The running war horse was directly hit in the neck by a grenade, the bones were broken, the war horse fell to the ground violently, the cannonball fell to the ground first, and then bounced slightly, sweeping the hooves of another war horse, the hooves of the war horse immediately became shattered, and immediately fell to the ground.

Although only a few shells hit the target, the real threat was the next few seconds.

With a bang, the cannonball that fell on the ground exploded, and the cannonball exploded under the belly of the war horse, knocking the nearby war horse and cavalry to the ground at the same time. Immediately after, one attack shell after another exploded...... Although the timing of these shells was not accurate, the shells that exploded one after another still blew up the charging Jiannu cavalry. Dozens of gunpowder smoke quickly drilled out of the horse team, rose into the air, and the violent explosion and thousands of fragments roared towards the nearby war horses, and those injured war horses immediately raised their front hooves, screamed and fell to the ground, throwing the Jiannu on their backs to the ground.

However, the exploding shells did not stop Jiannu's charge, and although in a short period of time, the artillery in the phalanx fired several times, but soon the charging war horses rushed in front of them.

"Kill ......"

At the moment of the charge, the Jiannu banner soldiers on horseback did not try to slow down, but with the help of the impact of the war horse, the spear stabbed forward with all its might, although at the moment of impact, in the face of the wall formation formed by the horse chopping knife, the war horse still instinctively wanted to escape those unknown risks. However, before turning the horse's body, they still stabbed their spears into the iron wall of the Ming army, and the Ming officers and soldiers with knives only felt a stabbing pain in their chests and abdomen, and then they fell down heavily.

Those Jiannu cavalry had long mastered a set of methods to deal with the Ming army's hollow gun formation, that is, to charge with cavalry spears, to break the wall with guns, although the dense hollow gun array seemed impossible to be overcome by the cavalry, but the cavalry guns that were one blow away still made the Ming army suffer a very heavy price.

However, the Ming army in the formation was not beaten in the face of the Qing army's cavalry charge, although the Tiger Camp was an iron man heavy rifle, but their weapons were not only sabers, but also the musketeers of the six generals, they were in the array, under the protection of the iron wall, and pulled the trigger towards the Jiannu cavalry.

In bursts of deafening gunfire, Jiannu's cavalry was constantly knocked down in front of the formation, but the cavalry from both wings still continued to attack the Ming army with their spears, they just hit and left, the tip of the gun pierced the armor of the Ming army, and the moment the Ming officers and soldiers flew away, they abandoned the guns and went away, sometimes, they would be hit by the horses behind, and hit the Ming army with a gun formation composed of chopping horses, pierced the body by the sharp tip of the knife, when the horse fell to the ground, the cavalry even picked on the tip of the knife, struggling and screaming on the tip of the knife.

The counterattack of the Ming army was extremely resolute, despite the repeated impact of thousands of Jiannu cavalry, but the Ming army in the formation still continued to attack them with muskets, a scorching lead bullet penetrated the armor of the Qing army, and blasted them off their horses, that is, in the cavalry wave-like attack, the once solid phalanx like an iron wall is being weakened little by little, when the soldier was pierced by the cavalry spear and fell, although the comrades in the back row would immediately meet him and stand in his position, but the soldiers were falling one by one, As the number of casualties mounted, the phalanx had reached a shaky point.

"Boom! ......At the same time, the artillery team of the Qing army was also bombarding this iron wall with red-coated cannons, and the former Great Wall was on the verge of collapse in the wave-like attack of the Qing army.

Seeing that the military array was on the verge of collapse, Chen Wudi, who was in the center of the military array, glanced in the direction of Zhong Shan, and then his gaze became resolute, and he silently picked up the horse chopping knife in his hand.

"Emperor Gao, the minister is here......"
