"Report to the general, the interception force has arrived at the specified position. Pen Fun Pavilion www.biquge.info"

"Report to the general, the men and horses of the headquarters have reached the designated position."

"Report to the general, the cavalry unit is on standby."

"Report to the general, the 7th, 10th, 13th, 14th, and 17th squads of the Navy are fighting on the river and are ready for battle."

"The order for a general attack will be issued in the form of signal flares, and after seeing the order of three consecutive signal flares, each unit will attack the enemy according to the original plan."

"Yes."

On the hill, watching the commanders of each unit disperse, Chen Xin sat back on the small horse, turned his gaze to a few large fireworks in the distance, and felt speechless for a while.

In accordance with its own orders, the ordnance factory found some fireworks masters to jointly develop the signal flares that they requested.

According to his own idea, the flare should be able to be loaded into a single-barreled flintlock pistol of the same caliber as a rifle, and can be fired lightly at any time, but after disembarking today, the actual objects sent by the ordnance factory were several thick barrels made of cardboard.

"Alas, forget it, it's going to be used, anyway, if it can be blown up, let them improve it later."

After thinking about it, Chen Xin's eyes turned to the enemy camp.

Although the various units of the Xuan army were not discovered because of the slackness of the enemy sentries when they were moving, it was impossible for the enemy not to know when the artillery positions were arranged, and the clanging sound of shoveling soil could be transmitted to the enemy's camp even if it was more than 500 meters away.

When the Xuan army was preparing for battle, the camp of the Houjin army was already panicked, and a large number of soldiers shouted to inform their comrades who were still asleep, and there were disheveled servant troops running around everywhere.

Chen Xin did not order the army to take the opportunity to attack, but waited for the enemy to slowly assemble.

This is not that Chen Xin is arrogant and arrogant, but the situation is different today, with 20 fast crabs of the navy coming to participate in the battle, the style of play is different from the infantry attacking by themselves.

A fast crab is fully loaded with 20 10-kilogram long-barreled heavy guns plus a 30-kilogram short-barreled heavy cannon, and 20 fast crabs are a full 200 10-kilogram long-barreled heavy guns, although because of the blocking of the mast of the sailboat, plus the application of battle line tactics, only half of the 100 10-kilogram long-barreled heavy guns can play a role, but the addition of 100 heavy guns is enough to affect the battle situation.

The 10-kilogram long-barreled heavy gun, as the main artillery of the Xuan Navy, is based on the imitation of Chen Xinyuan's Napoleonic 12-pounder cannon that will appear hundreds of years later. The prototype of this artillery was due to its high mobility, ferocious firepower, and the extremely simple manufacture and use of effective weapons.

Of course, it was impossible for Xuanjun to use pounds as a unit of weight, and when the final shape was finalized, a shell weighing 10 catties was chosen. And because naval shipbuilding requires a lot of copper, except for the first few guns, which are made of bronze, the later guns are all made of steel. The weight of the gun body was reduced to 800 catties.

However, Xuanjun was designing a naval gun at that time, and the gun body that was too light in weight had too much recoil after using a strong charge or even a double charge, and it was easy to fall backwards and smash the corresponding other gun behind it, so the ordnance factory lengthened the barrel length on the basis of the 14 times caliber gun body, increasing the weight of the gun body, so that it could be a little more stable.

The final 10-pound long-barreled heavy gun (naval gun type) is completely different from the Napoleonic run in Chen Xin's impression.

The caliber of the gun is 105mm, the barrel length is 20 times the caliber of 2100mm, the gun body weighs 1040 kilograms, and the 10 kilograms of iron ball shells loaded with it can reach a range of 1900 meters under the push of 2.5 kilograms of gunpowder at an angle of 5 degrees, and if it is a 10-degree angle, the effective firing range can reach 3000 meters.

This heavy artillery is capable of reaching a rate of fire of 2 rounds per minute in the hands of a well-trained soldier, and a rate of 4 rounds per minute if it is shelled with shotgun at close range, which is already an extremely terrifying rate of fire in this era.

With 200 of these powerful guns in his possession (though only half of them could be used each time), Chen Xin was no longer prepared to let his side fight the enemy.

The enemy's battalion was actually set up 200 meters away from the river, which was enough to defend against ordinary river warships in this era, but the heavy artillery of the Xuan army was a terrifying existence with a range of 3,000 meters.

And, most importantly, the casualties of the fighters have been large enough so far.

Looking at the enemy troops in the large camp, who had already gathered into groups according to their formation, and finally glanced at the time marked in the system, Chen Xin ordered "ignition".

In a moment, three huge fireworks were shot out as signal flares, cutting an arc in the sky, and then exploded with a bang, and the colorful sparks were eye-catching.

The entire battlefield was silent for a moment, and then it was as if a giant dragon had awakened from its slumber, and a thunderous roar continued to emanate from all gun positions.

Theoretically, as long as the artillery calculates the time and subtracts the corresponding length of the fuse, the shell can explode over the enemy's head and cause devastating damage to the enemy.

However, damn it, this is only theoretical, and in practice, for various reasons, it is impossible for artillery shells to explode accurately above the enemy's head in most cases.

Either it was early and exploded halfway through, or it was late and exploded after smashing into the crowd or flying through the crowd, so the effect of this grenade bomb was a little better than that of a solid iron bullet, only a little more limited.

The navy was responsible for clearing the enemy's living forces, and the army's infantry guns did not join in the excitement, and the small pipes, coupled with the limitation of range, the army pragmatically set its target on the enemy fence and those makeshift watchtowers.

An infantry gun cleared all the watchtowers with 3 pounds of solid iron bullets, and then began to clear the enemy fence from left to right.

Because of the instability of the army, the supply of grain and grass, coupled with the oppression of the servant army by the Jurchens, the servant soldiers in the Houjin army did not have to work, and the fence was directly shoddy, not only can you see big gaps from time to time, but even the diameter of the trees that make the fence has reached the point where it can be shot through by a rifle.

After discovering that the plugged shells would continue to fly far inside after flying over the fence, the members of the infantry artillery group decisively replaced them with No. 2 Dazi shotguns, and the dozens of large-particle shotguns in a medicine bag hit the enemy fence in the next day, and the speed of demolition and relocation was suddenly increased.

The Navy has always maintained a constant firing pattern of 2 rounds per minute, and after the temperature of the gun barrel reaches a limit, in a burst of horn sound, the ship uses the tail manpower propeller to turn 180 degrees in place, and can immediately change to the other side of the 100 guns to continue firing.

In order to prevent the enemy from being trapped and fighting, the infantry launched a counterattack on their own side, so the rate of fire did not use that combat rate of fire, and after setting aside a third of the artillery as a reserve, the remaining artillery kept using the rate of one round a minute, firing unhurriedly.

The enemy's internal blood flowed like a river, and the artillery of the Xuan army did not have the slightest pity, as long as the enemy did not surrender, they would bombard it today until they could no longer resist inside.
