The defenders of the outer defense line of the Jingzhou Machinery Bureau, realizing that something was wrong, began to take the initiative to advance to the perimeter, trying to expand the depth of the defense, and obtain enough forward firing positions for their own 100-mm cannons and other field artillery to counter the 150-mm cannons of the Daheng unified army.

But at this time, the Second Cavalry Army also gave up its horses, dismounted directly and fought on foot, digging trenches, building a perfect defensive line, and blocking several enemy assaults.

Wait until the next day when more trains arrive, more artillery units and ammunition arrive, and they are engaged in artillery operations.

On the third day, an infantry division marching lightly managed to reach the vicinity of the Beijing division and went into battle.

As time passed, more and more troops arrived.

On 29 June, Liang Chenglei arrived smoothly with the personnel of the headquarters and a large number of main forces.

On 1 July, all the troops scheduled to participate in the battle had already arrived in the area south of the Beijing Division and began to launch a fierce attack.

At this time, the Daheng unified army once again embodied the advantages of more troops and more artillery, and used the advantage of powerful artillery to directly smash the outer defense line of the Jingzhou Machinery Bureau, except for thousands of people who fled north across the river in a hurry, the remaining more than 10,000 people were all annihilated, of course, most of them surrendered.

It also includes the last main cavalry unit of the Black Sword Corps!

In this battle, the cavalry unit suffered more than 2,000 casualties, more than 1,000 fled north, and the rest were taken prisoner.

From this, it can be officially announced that the three-hundred-year-old Black Sword Corps has become history!

After overcoming the outer defense line of the Jingzhou Machinery Bureau, the Daheng Unification Army then smashed the enemy's resistance in the factory area of the Jingzhou Machinery Bureau, and finally completely captured the Jingzhou Machinery Bureau.

It's just that at this time, the Jingzhou Machinery Bureau has become a ruin, and the machine bureau has been shelled by 150mm cannons for many days, but they have been trying to maintain production, so the shelling has not stopped.

Up to now, most of the factory buildings of the entire Jingzhou Machinery Bureau have been destroyed, and a large number of machinery and equipment have been buried or blown up by the ruins of the plant, which makes Liang Chenglei feel extremely heartbroken.

This is the largest comprehensive arsenal in Daheng, but now it is in ruins.

However, although the factory was destroyed, a large number of workers, especially the technical backbone, and engineers did not suffer a big loss, some of them had already hidden, and some of them fled across the river to the north.

It is nothing if the factory and machinery and equipment are destroyed, but it is just to spend some money to re-purchase the equipment, and the most important thing is the technical personnel.

As long as the technicians are there, it will be easy to rebuild once the funds are in place.

Just like the previous Zishengzhou No. 1 Machine Bureau, the No. 1 Machine Bureau was destroyed more completely, but the casualties were not large, and the important technical personnel were all fine, so when Chongke City was taken to rebuild the No. 1 Machine Bureau, it was relatively smooth to have these people, and it was only necessary to repair its factory area and mobilize all kinds of machinery and equipment.

It's less than a year now, but the reconstruction work of the First Machine Bureau has almost been completed, although it has not yet been officially produced, but this is because the scheduled production weapons and equipment of the First Machine Bureau are not the current Luo An III rifles, but the Luo An IV rifles and a series of more advanced artillery equipment, resulting in the resumption of production has been delayed.

The reason why the Luo'an IV rifle has already been developed and equipped with troops is because several major rifle production factories such as the Fuyuan Ordnance Factory are now in a tight position, and it is impossible to stop for several months to transform the production line, and they can only directly establish a new production line for production during the reconstruction of the First Machine Bureau and several other arsenals.

If nothing else, starting in October this year, the No. 1 Machinery Bureau of Zisheng Prefecture will be able to start mass production of the Luoan Type 4 rifle.

At the same time, the machine bureau will also produce the latest types of artillery, including the 150 mm field gun that the army has not yet equipped, this artillery is in the process of research and testing, has not yet been put into actual combat a gun, with a 150 mm caliber, 23 times the caliber of the barrel, the maximum firing range can reach 8,000 meters, the marching weight is 7.5 tons, and the combat weight is 5 tons.

Once this artillery is successfully equipped, it will become the second most effective artillery gun in the army units of the Daheng Unification Army, second only to the 30-caliber 150-millimeter cannon converted from the naval gun, the 7,500-meter effective range of the 100-millimeter and 30-caliber field guns, and the 7,500-meter effective range of the 120-mm field gun.

Although its weight is also second only to the weight of a 150-millimeter cannon, but with a marching weight of more than seven tons and a combat weight of five tons, the Daheng Unification Army said that it was barely acceptable.

At the same time, it is expected that there will be a new type of 75-mm field gun of the 53-year model put into production, and the effective firing range of this 75-mm field gun will be 6,000 meters, because of the use of a longer barrel, its diameter has reached as much as 27 times, and the weight of the whole gun has reached more than 850 kilograms.

Of course, better performance also means higher manufacturing difficulty and cost, but compared with the so-called 75 mm 30 times the caliber and the range of more than 7,000 meters of the new 75 mm field gun, the manufacturing difficulty is much lower, and the cost is also low. There were only seventy-five mm field guns with an effective firing range of more than 5,000 meters.

The Ordnance Department of the Daheng Unification Army has high hopes for the No. 1 Machinery Bureau of Zisheng Prefecture, which is still under reconstruction, so that in the process of rebuilding the Machinery Bureau, almost all the machinery and equipment are the most advanced machinery and equipment in contemporary times.

In order to be able to produce more advanced weapons and equipment without affecting the progress of the current unification war, so that the Daheng United Army can continue to maintain its leading position in weapons.

After all, the opponent of the Daheng Unification Army is only a domestic feudal town now, but it will be other countries in the future.

At present, the R&D and production of many weapons and equipment of the Daheng Unification Army have actually begun to prepare for foreign wars after reunification.

The unification armored ship is the most obvious example, and the unification of Daheng does not need this armored ship of more than 8,000 tons and costs a huge amount of money.
