Twenty-three Houjin Hongyi cannons roared, iron bullets flew towards the earthen wall of Lushun, smashing up a mass of scum, after three rounds, the tide of shield carts came to the Lushun earthen wall, and the Houjin soldiers discharged two lines of shield carts, and there were even three layers in the middle.

Liu Pojun kept observing with a telescope on the city tower, issuing orders one after another, and after the Jin soldiers entered a mile, the twelve-pounder Hongyi cannon at the head of the city began to shoot, and the heavy iron bullets turned those seemingly sturdy shield carts into scattered wooden blocks, beating in the crowd behind, and the battle between the two sides was very fierce.

After 300 paces, the field artillery and Hongyi artillery of the whole line opened fire, and one after another the shield carts were smashed to pieces and fell behind in the rear.

After entering the pit area, the shield cart stopped one after another, rushed out of the coat behind, and threw the soil bags in the pit, which was much faster than their previous days.

Dengzhou's detachment shot with muskets at the top of the barrage ditch, and the armor of the obstacle clearance suffered heavy casualties, but the bow and arrow behind them pressed against them, forcing the group of coats to continue to clear the obstacle and fill the pit in front of the unprotected, the potholes were filled one by one, and as soon as the shield car advanced, the artillery fire in Dengzhou was still fierce, they maintained a rate of fire of about two rounds a minute, and continued to destroy those shield vehicles, and the Hongyi cannon on the wall bombarded the Jiannu echelon behind the shield car and broke up their formation.

The Houjin soldiers withstood the casualties, and finally advanced to ninety steps from the earthen wall, when a conch horn sounded, and thousands of light arrows rose into the sky. Pouring down towards the earthen wall, a dense popping sound sounded on the hanging on the earthen wall of the Ming army. The quilt against arrows was overgrown with weeds, and the overhangs on the earthen walls sheltered the soldiers. Most of the bows and arrows fired diagonally were blocked, and the soldiers on standby behind the earthen wall hid in the grass factory, which was also covered with wooden frames and quilts, which effectively resisted the bows and arrows, and the advantage of the defenders was fully revealed, and the auxiliaries and heralds who had to come and go began to suffer casualties, and some of the garrison soldiers who used turtledoves and Lumi guns returned fire behind the breastwork to fight back against the Houjin troops who filled the pits. The two sides entered the counter-fire.

The north wall of Lushun is in order, the observation post of Xiguan Mountain continues to transmit messages, and shoots intelligence with arrows on the mountainside, and the heralds under the mountain get it and ride to the north wall of Lushun, and the head of Lushun City also sets up a wooden lookout, and constantly reports the military situation to Liu Pojun.

After Liu Pojun got the information from Xiguanshan, he said to Chen Xin: "The Jiannu Chinese Army has four small copper cannons, which are mixed in the rear row of shield vehicles, and the subordinates are ready to transfer the first battalion artillery team to reinforce the middle road. Placed in the section of the earthen wall of No. 12 ......"

Chen Xin interrupted: "As you think, you don't need to ask for instructions for small-scale transfers." ”

Liu Pojun immediately turned around and gave the order to Tangma, and soon after, four four-hung carriages dragged the cannon from the flat ground behind the earthen wall to Guò and moved to the area of Yizi 12. The artillerymen from above quickly dismounted, unloaded the gun carriages, and went up the earthen wall along a gentle ramp. The surrounding auxiliaries stepped forward to assist, and the artillery carriage was quickly in place. The makeshift gun emplacements on the earthen wall were wider than the other earthen walls, which facilitated the abdication of the artillery. This is also an experience from the Franco.

Chen Xin observed the enemy camp with a telescope, Dengzhou Town's firepower was fierce, the accuracy of the field artillery in 100 steps was very high, the fragments of the shield car were continuously exploded on the front, and a group of firelight appeared on the ground, and the 10,000-bomb mine cannon overturned the coating of those obstacles one by one, but the shield car of Houjin did not decrease, after being hit and stopped, the back bypassed one and added to the front, the coating was also endless, the front just fell, and the shield car was driven out of a batch, and gradually even the Mongols were driven out. They scattered about a dozen paces in front of the shield carts, and fired their bows and arrows at the earthen wall.

The shield car stopped between seventy and eighty steps, countless coatings worked desperately in front of the shield car, stacking the remains of the shield car a few days ago in front of the new shield car, and thousands of Manchurian and Mongolian archers behind the shield car pulled their bows and threw them, and after five or six arrows, they replaced it with a round, maintaining their bodies, and the rain of arrows seemed to not stop, even if there were grass factories and hanging households in Dengzhou Town, they still suffered casualties.

In order to reduce their losses, the detachments retreated to the earthen wall in turn, climbed the crooked passages and retreated through the trenches, entered the breastwork in front of the earthen wall, and continued to shoot at the Baoyi and the Mongols against the breastwork. In this way, the earthen wall has two firepower, and it can be fired at the same time without affecting each other.

The garrison's Furlong machine fried beans sounded, Lushun's Furlong machine as many as three hundred, all of which were selected from the Dengzhou arsenal, the number was equivalent to Dalinghe City, a few days ago, Dengzhou Town hid the general Furlong machine, today in the face of the general attack of Houjin, all the Furlong machines began to explode, and the Houjin soldiers entered a hundred steps and immediately encountered the blow of these artillery, the Franc machines were all concentrated in the earthen wall front, each cannon was equipped with nine guns, more than 2,000 small iron bullets rained down on the shield car line, and the shield car screamed again and again, After being hit by an iron bullet, all the Jin soldiers had their limbs broken.

Thousands of firearms were fired in Dengzhou Town, the white smoke from the muzzles of the guns continued, the sea breeze blew gusts of gunpowder smoke away from the battlefield, and soon new white smoke erupted, and the sound of artillery on the mile-long earthen wall defense line in Lushun was filled with smoke.

Chen Xin's vision was also a little hazy, the five big red cannons on the north wall were another round of salvos, diagonally hitting the Houjin soldiers on both wings, the city wall trembled gently, the thunderous sound of the cannon shook the eardrums, Chen Xin opened his mouth slightly to relieve his tinnitus.

"My lord, Xiguanshan came to report, they observed that the coat behind the shield cart was piling up dirt bags into the shield cart." After Liu Pojun received the latest information from Xiguanshan, he said to Chen Xin.

Chen Xinchao observed from the front that after two four-pounder shells hit the shield car, the front guard plate was shattered, revealing the stacked dirt bags inside, "Jiannu is also going to repair a trench." ”

"The subordinates also think that they use dirt bags to pile behind the shield cart, this is an earthen wall, artillery cannot penetrate it, with this cover, they can be stationed behind the wall, and there is no need to retreat at night."

"Jiannu wants to learn the trick of Da Linghe in Lushun?" Chen Xin was puzzled: "But Lushun has a port, if they want to besiege it, then they should mainly attack Tiger Tail or Golden Mountain, but the lookout post did not find that they sent additional troops in those two directions." ”

Liu Pojun thought for a moment and said: "Maybe Jiannu built an earthen wall, relying on the cover of the earthen wall to dig trenches or tunnels day and night. Attack our line of defense nearby, possibly after the earthen wall is built. Then draw troops to attack the tiger's tail. ”

"Was there a plan to deal with burrowing and trenching?"

"The on-site deduction of the Military Orders Department has been proposed by a staff officer to dig tunnels. After the test, we found that it was quite difficult, we had a trench of nearly one zhang to block it, and their tunnel had to go deeper than one zhang, and the underground of Lushun was damp, and there was a lot of water seepage, and the tunnel was very easy to collapse, and it was very inconvenient for the soldiers to move. Even so, we still bury a listening cylinder every few dozen steps, which should be worry-free. The other is to approach with a trench on the ground. This method is more effective, but our earthen walls are in the shape of rows of acute angles, and as long as they are advancing, there will always be a wall that can hit the ditch, and then increase the fire in the corresponding direction. ”

Chen Tou, Jiannu's reaction was faster than he imagined, but the forces in the war were always the best to learn, and after they encountered the red-coated cannons defending the city, they were able to create the tactics of besieging the city in this era. Then it is reasonable to extend the siege tactics of the trenches.

Later, the golden shield car array stopped all the way, and the coated ants behind it came and went, throwing all the pre-loaded dirt bags onto the earthen wall, as well as the fragments of the shield car from a few days ago. It has become the material of this shield wall. The distance chosen by Abatai was between 70 and 80 paces from the earthen wall, which was suitable for throwing arrows and arrows, and the largest number of Furlong machines could not effectively penetrate the shield cart. It can also be seen that they have used their brains.

After the Jin soldiers struggled to lose a large number of coats, they quickly built an incomplete earthen wall. But it can effectively cover his troops, especially the Dengzhou field artillery, which is the most threatening.

Tens of thousands of coatings dug trenches behind shield carts. The excavated earth was piled up behind the shield cart, and the earthen wall was reinforced step by step. Dengzhou's artillery gradually stopped firing, and both sides were temporarily unable to effectively hit each other, and after a fierce battle, they entered a standoff.

Chen Xin asked Liu Pojun: "What is our next step?" ”

"Jiannu is blocked by the earthen wall, and the attack cannot be sustained in a short time, and the subordinates plan to take advantage of the fact that the earthen wall is not yet stable, mobilize the mobile forces on both wings, and make a flank posture to attract Jiannu to gather, and I will concentrate on shelling it with artillery to kill and injure its Zhenyi elite. Especially on the side of Xiguanshan, their shield car formation was too straight, and the flank cover was insufficient. ”

Chen Xin agreed: "Very good, their earthen walls are still very messy, and the two wings especially lack cover, we must take men and horses out to resist, go and execute, let's mix the horses and horses." ”

Liu Pojun sent Tang Ma to inform, the two wings of drums and trumpets sounded in unison, as the cavalry of the general reserve temporarily attacked, especially the Xiguan Mountain under the sandwich road, the cavalry from the sea earthen wall passage into the Xiguan Mountain and the earth wall between the sandwich, here is the reserved sortie position, under the firepower of the two pairs, if the Houjin soldiers can not capture Xiguan Mountain, they will not be able to attack here, but as the defender's counterattack assembly place, it is the best.

There is also such an area at the foot of the Golden Mountain, which is smaller than that under the Xiguan Mountain, and in addition to the cavalry, there is also an infantry of each division, making a sortie posture.

Because of the threat of the Ming army on Xiguan Mountain, Houjin's shield cart could not be covered in the front, and the two wings became their weakness, they seemed to want to make an arc, but the blow on the west side was very fierce, causing their shield car to lose Yan zhòng, at this time it was only enough to cover the front, and the protection of the right wing was very empty.

A wooden platform on Xiguan Mountain continued to play the flag, using a good perspective to transmit signals to the Dengzhou Army under the mountain, Liu Pojun looked at the flag with a telescope, and read word by word in his mouth: "One thousand vests, No. 7 region." ”

Chen Xin is also reading, but he can't understand, speaking of which is still his main credit, when Wang Zheng arrived in Dengzhou, his book "Far Western Strange Instrument Illustrated" has Western letters and pronunciation, Chen Xin temporarily made a move, let Liu Min have a pinyin table, and then there is now this standard flag, although it is still in the experimental stage, but it has shown great advantages for short orders.

All the areas facing the defense line are numbered, and the lookout posts have to train with a marked map every day, accurately judging the enemy's position without a marker, and each artillery position also has a gun gauge table for different areas, and after test firing calibration, Dengzhou Town's preparations are far more complete than Huang Taiji imagined, and it has long been beyond his cognition.

Each gun position was adjusting its charges, angles and gun gauges, and there was a brief silence on the battle line, and then the Jin soldiers thought that they had the cover of the earthen wall and were not afraid of the attack of the Ming artillery.

The artillery banner reported by each artillery position was raised, and the artillery command flag with red background and yellow border around Chen Xin sharpened the flag for a week, waving left and right. The silent Ming army front suddenly broke out, all the artillery positions that could be reached were firing, they fired at the fastest speed, reaching a speed of three rounds per minute, hundreds of shells swept across the outer array of the two white flags in the array, and the Hongyi artillery on the city wall also hit that position, the mobile force of the two white flags was in chaos, and the horse armor and infantry took refuge next to the earthen wall.

Liu Pojun said to the bannerman beside him: "Give Tan Shen an order, and the cavalry will assault the right flank of Jiannu." ”

A moment later, more than 700 cavalry lined up in a strict formation, quickly entered the battlefield from the starting point of the left flank of Dengzhou, and rushed towards the two white flags that were caught off guard...... (To be continued.)
