In order to reduce their losses, the special service platoons, under the orders of the commander, withdrew to the side of the rammed earth wall in turn, and then climbed the crooked passages and retreated through several successive trenches, and entered the breastwork in front of the rammed earth wall.

Here, again, the soldiers of the special service platoon leaned against the breastwork, and continued to shoot at the Baoyi and Mongols, as well as the occasional Jurchen archers with their heads out.

In this way, there is a fire net on the rammed earth wall, and a fire net in the chest wall under the rammed earth wall, and the Huaxia army has two firepower on the first line of defense, which can shoot at the enemy army without affecting each other.

The small-caliber smoothbore guns of the armed garrison sounded like fried beans, and the number and types of such small-caliber smoothbore guns on the Lushun defense line were very large.

Furlong machines, mountain splitting artillery, tiger squat artillery, and the infantry artillery exclusive to the Huaxia Army, not counting all kinds of field guns and howitzers with a caliber of more than 100mm, these small-caliber smoothbore artillery, as many as 3 or 4 hundred, were selected from the arsenal of the Ming Dynasty by the generals of Dongjiang Town.

In the battle a few days ago, the Huaxia Army deliberately hid a part of the small-caliber smoothbore guns, just so as not to irritate the Houjin Army too much. Today, in the face of Houjin's desperate general attack, all smoothbore guns except for the 155mm rifled heavy guns began to be fired.

When the soldiers of the Houjin Army entered 1500 meters, they immediately encountered the blows of field artillery and howitzers, and the artillery fire suffered by the Houjin Army was not so dense at this time, after all, the number of large-caliber guns on the Huaxia Army was not too much.

And when the Houjin army reached a range of about 200 meters, it was considered to know what a rain of bullets was, and the enemy was immediately hit by a large number of small-caliber smoothbore artillery.

You must know that almost most of the small-caliber smoothbore guns on the Huaxia Army's side are concentrated on the rammed earth wall.

And the small-caliber smoothbore accounted for almost half of the number of guns, which happened to be the Furlong machine collected from the arsenal of the Ming army and the 40mm infantry gun made by the Huaxia Army.

Among them, the Furlong machine was equipped with several sub-guns for each gun, and the infantry guns were also equipped with fixed ammunition, and suddenly thousands of small iron bullets hit the line where the shield car was located like a torrential rain, making the front and rear of the shield car array scream miserably.

The soldiers of the Houjin Army, who were hit by small particles of iron bullets, were all rotten and fragmented, which was simply a situation in the Shura field.

Hundreds of small-caliber smoothbore guns of the Huaxia Army, plus rifles in the hands of thousands of soldiers, so many firearms fired at the same time, and the white smoke on the muzzles of the guns continued to rise outward.

In this case, within a few minutes, there was smoke everywhere, and people couldn't see anything clearly.

Fortunately, Lushun is next to the sea, and the gusts of sea breeze are blowing, and the constant gunpowder smoke blows away from the battlefield, so that the two sides can maintain a certain vision.

However, because the Huaxia Army is an all-firearms unit, new gunpowder smoke will soon erupt from the muzzle of the gun, and once again fill the field of vision.

The sea breeze and gunsmoke are like two naughty children constantly tugging at each other, but this does not delay the fight of human beings. On the defense line of the rammed earth wall several kilometers long in Lushun, there was still the sound of artillery and smoke.

Chen Xin's vision was also a little hazy, and several field guns on the north wall fired another salvo, striking the Houjin soldiers on both flanks, and the stone brick-wrapped city walls trembled gently under the roar of artillery.

The sound of cannons shook everyone's eardrums like muffled thunder, and Chen Xin knew that it was not good for the ears, so the artillerymen of the Huaxia Army generally stuffed two balls of cotton in their ears, or with thick leather ear protectors, to relieve the symptoms of tinnitus.

After receiving the latest information from Jiguanshan, Chief of Staff Liu immediately said to Chen Xin: "Your Excellency, Jiguanshan sent back the military information, and they observed that the coat behind the shield cart was piling up dirt bags inside the shield cart. ”

Chen Xin observed the enemy troops in the front direction, there were two 40mm caliber infantry cannon shells, and after hitting a shield cart, the front guard of the shield cart was suddenly shattered, revealing the stacked dirt bags inside.

Chen Xin immediately knew: "Tartar is going to build a trench there." ”

"The subordinates also think that this is right, they use dirt bags to pile up in the shield car, or behind the car, after completion, it is a rammed earth wall, the general small-caliber artillery can not penetrate the thick rammed earth wall at all, once the Tartars have this cover, they can garrison behind the wall, and at night there is no need to retreat to rest."

Chen Xin muttered to himself, "This trick looks familiar!" ”

"Junshan still remembers the battle between Da Ming and Hou Jin in the first half of the Battle of Da Ling River?" Chief of Staff Liu reminded him slightly.

Chen Xin also recalled immediately.

"Tartar, this is the way you want to learn Da Linghe in Lushun?" Chen Xin was a little puzzled and said: "But Lushun is near the sea, there is a deep-water port, if they want to besiege our army, then they should focus on the two commanding heights of the Tiger Tail or the Golden Mountain, which hold the waterways in and out of the port."

However, so far, the scouts, watchtowers, and observation units everywhere have not found that the Tartars have sent more troops in those two directions. ”

Chief of Staff Liu thought for a moment and guessed: "Perhaps, the Tartars want to build a rammed earth wall, relying on the cover of the rammed earth wall's close-range bow and arrow, digging trenches or tunnels day and night, and attacking our defense line nearby.

There is also a great possibility that after the rammed earth wall is completed, a part of the troops will be transferred to attack one of the two places of Tiger Tail and Golden Mountain. In short, the focus of our army should now be on the trenches or potholes dug by the enemy. ”

"Has the General Staff made relevant plans for dealing with the enemy's means of digging holes and trenches before?"

"When the General Staff Department was conducting actual combat exercises on the spot, a staff officer proposed a method of digging tunnels, but after the experiment, he found that this method was very difficult.

Our defensive line lies and is able to have a trench nearly 3 meters deep to act as a barrier. The underground of Lushun is damp, and there is a lot of water seepage, as long as the tunnel goes deep into this point, it is easy to collapse, and it is very inconvenient for soldiers to move and transport.

Even so, our army still buried a large water tank at a distance of more than 100 meters behind the rammed earth wall in the rear, and under these measures, our army should no longer need to worry about the enemy's tunnel offensive.

In addition, it is the trench that is dug in the ground and gradually approached. This method is a bit more effective than authentic. However, our rammed earth walls are made in rows in the shape of bastions, and the walls and opposite sides are almost at acute angles.

At this angle, if the opposite Tartar digs a trench and advances, there will always be a wall that can hit the trench dug on the opposite side, and at that time, it is enough to intensify the fire in the opposite direction. ”
