Every time they go to the clearing outside of Blackiron Town, Lauren and Miley are especially excited. Pen, fun, pavilion www. biquge。 infoBecause it means that Lord Renault has developed a new weapon and is going to test fire.

In order to arm merchant ships, Renault used a thousand degrees of search to browse through a lot of knowledge about artillery.

If you don't look at it, you don't know, the definition of cannon is too broad.

Starting from the ancient bronze cannons, to the super cannons that can hit space, there are so many types and complexities that Renault almost lost his head, and secretly sighed that he was really like a mountain, and he hadn't studied anything, only relying on the superficial knowledge he had searched thousands of degrees, and it really took a lot of thought to develop a cannon.

Finally, Renault designed a howitzer based on the style and principle of the howitzer.

In fact, Renault doesn't know how to define this gun, its bore diameter is 152 mm, the barrel length alone is more than 3 meters, plus the bracket, base, and running gear, the total weight is more than 4 tons.

And the shells it used cost Renault a lot of brains.

The most troublesome thing is the cartridge, that is, the cannon case. Originally, it was planned to use brass, but with the current technology, it was much more difficult to process copper than steel, so steel shells were chosen.

The warhead casing is all copper, firstly for airtightness, and secondly, to prolong the service life of the barrel.

So for the 10 shells used for the test firing, Renault spent three days in the machine shop to make the shell, primer and fuse.

Of course, the loading was still black powder, and in order to obtain effective data, the amount of push powder of the three experimental shells was different, but the quality and shape of the warheads were the same.

The total weight of the shells exceeded 45 kg, and it took two people to carry them to fit into the barrel.

When they arrived at the venue, the seven Black Iron Army soldiers neatly set up the heavy cannon. Unlike heavy mortars, howitzers generally fire at a small angle, so the initial test firing was set at 30 degrees.

The shells were loaded, the heavy firing mechanism was firmly held together by the barrels, and Lauren stood next to the barrel with a grin, holding the string of the firing pins in his hands, waiting for Renault's order.

The domestic Type 54 152mm howitzer has a maximum firing range of 12 km. But that's a prerequisite for having advanced processing technology and gunpowder technology.

The barrels and shells made by Renault have a large error in accuracy, plus they are ordinary black powder, so he is satisfied that he can break through the firing range of 5 kilometers.

As for the accuracy of the strike, let's wait until the shells are fired.

"No. 1 experimental bomb, prepare - release!"

With a command, Lauren pulled the rope violently, and the powerful firing pin slammed into the primer of the cannonball.

Boom -

It's like putting a detonator overhead, and the barrel of the gun spews out huge black smoke.

Except for Renault, everyone was so frightened that they squatted on the ground, and their hearts couldn't help but pound.

Even Renault held back for the image, m's, it was so exciting, he finally realized what it means to be thrilling.

When I used to watch movies, I always felt that those artillerymen were very comfortable, far from the rear, and received an order to fire at a certain high ground, and then everyone just put it down.

Now he finally knew that firing artillery was not only a technical job, but also no worse than the soldiers on the front line.

Boom -

The sound of the explosion in the distance finally came back, and Renault immediately asked people to measure it on the spot, and finally got accurate data: the range was 4,600 meters, and the deviation to the right was 300 meters.

It's pretty good that you can hit so far with rough black powder, and it's the least pushed potion yet.

"Test Bomb No. 2 is loaded, ready to be released!"

Boom -

It was still earth-shattering, and the black smoke from the barrel of the gun rushed into the air, like a small black cloud.

The second shell had a range of 5500 meters and a deviation of 350 meters to the right.

It was all deflected to the right, Renault asked the soldier to adjust the sight on the barrel, and the third shell was fired, and the range was also about 5,500 meters, but the deviation was reduced to 80 meters.

Renault was not satisfied with such a result.

One is that the firing range is too close, and it is not much longer than a heavy mortar. After all, howitzers have an advantage over mortars, in addition to their lethality, they have a super long range. However, if it is necessary to launch a warhead of more than 20 kilograms for several kilometers or even more than ten kilometers, the crude black powder can no longer meet this requirement.

It seems that the gunpowder technology can't keep up, and I hope that this mission will be completed and the relevant rewards can be obtained.

In addition, the volume and recoil are too large, and the caliber needs to be changed when mounted on the ship, and the turret needs to be re-erected on the city wall.

Just as she was about to call it a day and go back, Anna suddenly fell from the sky and brought a not-so-good news.

Luo Xi led a huge cavalry team, and he had reached Black Iron Town for more than twenty kilometers, and it was estimated that he was now close to the nameless pass.

Renault raised his eyebrows, this guy's luck is not ordinary, as soon as he made a howitzer, he rushed over to be a target.

"How many are there?"

"About 10,000, all of them are light cavalry, and there are no supplies. ”

10,000 cavalry is not a small number, Renault has never even seen 10,000 people get together, let alone 10,000 cavalry, how huge is that scene?

It seems that after the lesson of the last time, Roshi has learned wisely this time, abandoned the infantry with limited mobility, did not carry supplies, and gave full play to the advantage of the cavalry's fast movement.

Once they break through the city gates, the horses' hooves alone can fill Black Iron Town.

Thinking of this, he had a strange smile on his face.

Luo Xi is really caring, every time he knows that he is short of people, he will send him people and horses, it seems that it is right not to kill him, keep Luo Xi and slowly get rich.

"Hehe, it's fun again!" Miley clapped her hands, unable to hide the excitement on her face.

The guards who remained in Blackiron were all new recruits, and under her and Anna's training, they were already very skilled in various skills. But they haven't seen fire and blood, and they're not real soldiers yet.

And the 10,000 cavalry sent by Roshi this time is the best tool to hone them.

Renault asks Lauren to take her back to Black Iron to gather the army and try to keep Roshi five kilometers away.

The terrain is flattened there, with large open flatlands and small rivers between the mountains. Roshi will definitely be there to feed the horses and adjust their formation.

"Pull the cannon back, set it up on a high spot, and we'll give Roshi a taste of the power of the new weapon. ”

......

Led by Anna to a height of thousands of meters, Renault saw the cavalry team like a long dragon at a glance.

How many 10,000 war horses are there, according to the four horses side by side, each war horse plus the gap is counted as three meters, and the team is also stretched to more than 7,000 meters.

This formation is certainly not suitable for attacking, but it is also troublesome to attack such a formation. (To be continued.) )
