Chapter Twenty-Three: The Tiger Squats Cannon

Thinking of fighting with the cavalry in the plains, Shi Bin felt that it was very thrilling and he had to develop firearms with all his might, but he tossed and turned in bed and never came up with a suitable firearm.

"Big brother, we have a lot of cavalry in the north, and we have to make practical weapons to fight those Yuan people in the plains." Wang San also spoke.

Indeed, the infantry of the plains battle may have to rush over for a minute, and during this time they can still shoot a few arrows for a little defense.

Cavalry, however, was completely different. Generally speaking, the weight of the ancient Mongolian cavalry was generally about 50 kilograms, and they wore light armor when sprinting, with a saber, a light battle axe, a bow, 12 arrows, a saddle, a bridle, and a stirrup, which were about 50-70 kilograms. In this way, the dwarf Mongolian horse carries about 120 kilograms.

Combining these factors, the sprint speed of Mongolian horses is about 40-50 kilometers, which means that the Yuan cavalry can run 800 meters in one minute.

The lethality of a bow and arrow does not exceed eighty meters, and a qualified archer needs to train for at least three to five years, and the strength of an archer in a battle is at most twenty arrows.

In other words, a small number of crossbows and crossbows were useless against cavalry.

The word "chicken ribs" appeared in his mind, it was really meatless, and it was a pity to abandon it.

When Shi Bin was very depressed, Zhao Gang said, "Big brother, I heard that we still have a lot of cannons?" Can't it be shelled? ”

"Bombardment?" Shi Bin smiled helplessly: "Brother doesn't know, the artillery does have a long range, and the power is not small, the problem is that it is difficult to move thousands of catties at every turn; The accuracy is still poor, and it can only be targeted; And the rate of fire was too slow, and after less than two shots, the cavalry of the Yuan army had already rushed to the front. ”

Zhao Gang was also speechless after hearing this, while Wang San said: "I can't see it completely, at least I can carry out a close-range coverage strike." It's a big deal to develop weapons that strike at a long distance and in a wide area, and weapons that can effectively resist the impact of cavalry. ”

This is also true, if the infantry must not be able to defeat the cavalry and even resist it, otherwise the Central Plains Dynasty would have been destroyed long ago? Since the accuracy is not so high, improve the accuracy, and find a way to increase the rate of fire or increase the range of fire if the rate of fire is not fast enough.

Determine this goal and think of what is feasible. After sitting so empty for an afternoon, I thought about it and thought about it, and all I had in my head were the French M1897 75mm rapid-fire guns and the German Maxim MG08 machine guns.

Knowing that it was useless to sit and think like this, he simply went to the armory to visit and see if the Song army had any practical weapons that could resist cavalry. When I entered the armory, I saw earth-shattering thunder, rockets, assault guns, and some heavy primitive artillery. But it's not practical, so it's better to shake the sky and rockets.

On his way back to the camp, he heard the sound of "knock, knock, knock" not far away, and it was when he was extremely irritated that he heard this sound and raised a nameless fire to teach the guy who made the sound a lesson.

When he walked there, he saw that it was just a farmer in the Umi, and looking at the giant stone tool in the shape of a wine cup placed on the ground, Shi Bin vaguely remembered something. Although I looked at the stone mortar carefully, I only thought of the can, which was obviously not the right object. Seeing that it was already dark and the camp was about to close, Shi Bin also turned around and was about to go back, when suddenly a violent explosion was heard in the distance.

"Mortar"! Shi Bin finally remembered the weapon used by the Red Army in the War of Resistance against Japan that he had seen in the TV series.

At that time, the Red Army did not have any heavy weapons, but to confront the well-equipped Japanese invaders, it had to build some low-cost and low-tech earthen artillery. This mortar is the most impressive one.

In order to facilitate the carrying of the Red Army, oil drums were used as artillery bodies, and shells were made of gravel and broken iron, and these "scattered shells" were fired after being ignited with fuses. Only then did Shi Bin understand why he always thought about cans but couldn't figure it out.

Isn't this mortar the most primitive form of mortar? Although the range of the mortar is only about five kilometers, it is superior in its fast rate of fire, large strike range, and light and easy to carry. Thinking of these Shi Bin is much easier, doing some research along this line of thinking should be able to create a light and powerful artillery.

However, this high-quality iron bucket Shibin could not be made, so he could only thicken the barrel of the artillery. Thinking about it, it reminded him of a person------- Qi Jiguang. Isn't there a small artillery in the Qi family's army? The name is quite mighty--- tiger squat cannon.

So he immediately gave another order to make a tiger squat cannon, and wrote down the standard in detail:

The head and tail are 2 feet long, with 7 iron hoops around the body, and the gun head is erected by two iron claws, and there are iron stumbling, with a total weight of 36 catties.

Thanks to Shi Bin's kindness and the enthusiasm of the craftsmen and workers, three samples were built the next day, two of which were slightly heavier tiger squat guns of their own design.

The effect after the test launch is very good, the effective range of 36 catties has reached 500 meters, and the other two slightly heavier ones have also reached 800 meters. This result made Shi Bin very happy, at least within 800 meters, he could carry out a covering attack on the cavalry of the Yuan army.

And the Tiger Squat Cannon is equipped with a direct aiming device to make the attack more accurate.

In view of the slow reloading speed, gunpowder and shells were prepared in advance in parts, and the Tiger Squat Cannon was divided into three rows for three-wheel firing. In this way, the firing interval of the Tiger Squat Cannon within 800 meters was very short, which greatly improved its ability to resist cavalry.
