After the four phalanxes came out together, a formation of two front and two back, Tianzi was listed, which was the so-called fish scale array.

After the large array was formed, the cavalry moved to the left side of the fish scale formation.

Finally, a group of soldiers who were a little flustered, under the help of the officer's drinking and kicking, rushed out of the woods in a hurry, and it took a long time to line up three large horizontal rows behind the fish scale array.

Then, under the hoarse voice of a sturdy man in the three large horizontal rows, he barely maintained his formation and slowly pushed forward.

Unlike Chen Xian's more dense phalanx, the military formations of this era were relatively sparse, and there were large gaps between people, and these three horizontal rows passed through the gap between the soldiers of the fish scale formation and advanced to the front of the large array.

At this time, the opponent's large array was finally fully formed.

Chen Xian was like a fool, just watching the other party's military formation take shape.

The battle formation took shape smoothly and perfectly, and while Liu Erzu breathed a sigh of relief, his doubts became even heavier.

Although he was puzzled, but now, a big battle is already on the way, and it has to be sent, Liu Erzu took a deep breath and gave the order for the whole army to advance.

Chen Xian's military formation did not move at all, and just watched the other party's large formation advance little by little.

500 meters......

400 meters......

300 meters......

Chen Xian suddenly gave an order, "The whole army unfolds in one word!" ”

Following Chen Xian's order, the two companies in the rear first walked dozens of steps to both sides, then turned forward, and walked to both sides of the two companies in the front row.

Liu Erzu on the other side was even more confused when he saw this change of formation.

The opponent has no cavalry, and the team is spread out horizontally, so that the depth is seriously insufficient, and it is easy to be swept through by their own cavalry?

Or, if you send troops to detour behind the opponent and attack, the opponent only has a horizontal platoon, which is bound to be unable to protect the behind, which is even more dangerous.

Before Liu Erzu finished turning the doubts in his mind, Chen Xian issued a second order, "Three catties of main artillery and two artillery on the left, target, cavalry, two artillery on the right, and ...... on the left front of the target."

Hearing the order, the artillerymen, in accordance with their usual training, quickly aimed ......

"Fire!"

Rumble! For the first time, the roar of cannons sounded in this world......

Chen Xian used to read historical data, and often saw that the average rate of fire of flintlock pistols was three rounds a minute, and some sources said that Napoleon's gunners could reach the limit rate of fire of ten rounds a minute.

This made him feel incredible, how the rate of fire of a cannon is faster than that of a musket, this is unreasonable!

It wasn't until he really came into contact with this kind of front-loading cannon that he realized that the cannon had a faster rate of fire than the musket, which was actually a matter of course.

The principle and process of firing from front-loading muskets and front-loading guns are actually almost the same.

The barrel is cleaned first, then the gunpowder is loaded, and then the musket is poured into the external reservoir of gunpowder, and the gun requires the gunner to pierce the gunpowder bag in the barrel with a long needle through the ignition port, and then pour gunpowder into the ignition port.

Finally, the musket moves the bolt and hangs the reeds in preparation for firing, while the gun is held by the gunner and waits for the firing to be fired.

You see, the process steps on both sides are almost the same, but the artillery is much larger than the musket, how can it be that the artillery fires faster than the musket?

Anyone who thinks this way actually ignores the number of people who operate artillery and muskets.

An artillery often requires three to five people to operate at the same time, and the division of labor between these people is equivalent to dividing the firing process of the artillery into several sections, going hand in hand, and the time is naturally shortened.

However, the musket has no way to divide the labor among multiple people, and can only complete all the steps from beginning to end by one person.

This is the same as two sections of the same length of road, one road is easy to repair, but only one engineering team builds, and the other section of the road is difficult to repair, but there are four or five engineering teams in the place where they do not understand the start of work at the same time, and finally the section of the project is closed, who is fast and who is full, it is naturally clear at a glance.

Of course, ten rounds a minute is the limit speed of Napoleon's elite artillery, and of course the artillerymen under Chen Xian who have been trained for several months can't do it, but it is not difficult to do about five or six rounds a minute.

Five cannons, one shot each for ten seconds, which sounds like a cannon on the other side.

These shells were fired by the barrel at a small elevation angle of less than 10 degrees, and the low-flat trajectory drew a hellish line in the opposing military formation!

Speaking of elevation angles, Chen Xian used to look at historical materials, and in the domestic materials of the late Ming Dynasty, it was always said that the red-coated cannon eroded dozens of miles with one shot, but in foreign materials, even in the Napoleonic era, the effective range of the artillery was only more than 1,000 meters, which seems to be a big boast in Chinese historical materials.

But in fact, there must be an exaggerated component, but it is far from as big as the average person thinks, the firing elevation angle of artillery in the Napoleonic era is very small, generally within ten degrees, and in the late Ming Dynasty, people do not know ballistics, in order to pursue the range, often take a large elevation angle of twenty or thirty degrees, the same cannon, the same muzzle velocity, take different elevation angles, often achieve a difference of several times the range.

The advantage of a low flat elevation angle is that a low flat trajectory can be obtained, that is, the projectile can travel a longer distance at a height that can kill people.

A cannon with a large elevation angle of 35 degrees may be able to hit ten miles away, but the trajectory of the high throw makes its killing range almost shortened to a point.

However, if the same cannon adopts a low flat elevation angle of five degrees, the shells fired by it will fly dozens of meters within the lethal altitude of two meters to the bottom, and the killing range will be expanded from one point to a line, and the lethality will be greatly increased.

Another benefit of the low flat elevation angle is that it is easier to form vibrating eggs.

Anyone who has ever been in the water knows that the lower the pressure of the thrown stone, the easier it is to jump again, which is the principle.

A shell fired at a low flat elevation angle of less than 10 degrees, as long as it does not encounter some extreme conditions, will inevitably form a ricochet, and the lethality of the ricochet is sometimes more terrible than that of a direct-fire shell......

Chen Xian's guns were designed with a maximum elevation angle of only 10 degrees, and at this time, the shells fired at an elevation angle of five or six degrees could almost sweep the entire military formation on the opposite side at a lethal height......

The shock of a person who saw the lethality of a shell for the first time was unimaginable to those who had not felt it.

The three-pound and two-pound shells swept through the military formation, leaving only a string of smashed human bodies, and after a pound of cannons penetrated seven or eight people, they were left on the body of the last person, or fell to the ground with all their strength, so that they could finally see the appearance of this murderous weapon......

Seeing this tragic scene for the first time, even the battle-hardened soldiers were frightened, and the entire army on the opposite side suddenly became chaotic.

The cannon bombarded at full speed for nearly three minutes, and according to experience, at this time, the barrel was already very hot, and Chen Xian called off the shelling.

At this time, the military array on the opposite side was completely scattered......
