Chapter 262: The most important thing is range

Ten Hongyi cannons began to be loaded with firing gunpowder, increasing the gunpowder by half will not have safety problems, but it cannot be used for a long time, otherwise it will affect the temperature and cleanliness of the barrel, and seriously reduce the firing efficiency, so only in special times, Hongyi cannons will add more than the standard amount of firing gunpowder. （）

These gunners couldn't see the woods a few miles away, but under the guidance of Zhao Tianyou, they roughly aimed in the direction and made a small salvo, which was a little response to the Yuan army's test firing of artillery. Ten shells exploded in the woods, killing and wounding thirteen Yuan scouts who were looking for shells, and at this time, they also found the solid shell that had been fired two miles away from the Yuan military academy.

This cannonball is lighter than the cannonball used with the cannon, and according to the design of the cannon's caliber, the weight of the normally fired solid iron projectile should be controlled between 60 and 70 catties. This 46-pound shell is a one-time test shell, and the purpose of this shell is to be able to fly a little farther so that the results of today's test firing can be explained in the past.

Boyan turned a blind eye to the artillery bombardment at the head of the city of Guangzhou, and by no means affected the overall morale because of the death and injury of a few scouts, and the celebration banquet of the test-firing of 10,000 catties of artillery was still held as scheduled. There are still five cannons in the workshop waiting to start casting, because the craftsman in charge is not confident enough to dare to fire and cast them all overnight, but first concentrate manpower to carefully build one, and then start casting after inspection.

"General Zhao, we have to find a way to destroy the cannons of the Yuan soldiers, we can't see that they have built the cannons, let's wait to fight us, but unfortunately our range is still not enough, if only we could directly hit their camp."

Liu Changhai didn't feel right after speaking, so he smirked a few times. If the cannon in Guangzhou had such a long range, the Yuan soldiers would have run back to Qingyuan to camp, could they still build a camp six or seven miles outside the city and arrange a workshop to cast the cannon!

"We don't know the location of the workshop, even if we send tens of thousands of elite soldiers, we can't destroy it, don't forget that it is in the camp of more than 100,000 yuan, if it is so easy, Boyan would have been driven back to the grassland, and the world would have been peaceful for a long time.

However, there is a way to prevent it, it is rumored that the cannon built by the Yuan army is very large, and the sound of the cannon just now also proves this, and a cannon of that weight has a disadvantage that it is difficult to move. According to the location of their battalion, the artillery of the Yuan army can also hit a range of about three miles, what tactics do you say should be used to deal with them? ”

Zhao Tianyou never forgot to support Liu Changhai, and when he had something to do, he took some questions to test him.

Liu Changhai tilted his head and thought for a while and said, "Assuming that their maximum firing range is three miles, then the first problem we need to consider is to let the artillery of the Yuan army have no chance to get close to within three miles."

In this way, they will not be able to open fire, even if they are reluctant to fire, and they will not be able to kill and injure the soldiers who threaten our city. Even if we can barely reach the city wall, our ammunition and firearms are scattered, and the method of storing ammunition in the inner city parapet can avoid the enemy's artillery fire causing fire, or directly hitting the ammunition depot.

However, the most effective and direct way is to go out of the city to attack the Yuan army, and destroying their cannon barrels is the most effective, they can only turn into molten iron cannons, haha, they will definitely be able to kill Boyan. ”

Zhao Tianyou nodded and said, "You quickly saw that the most important point of the problem is to keep the enemy's artillery away from the effective firing range, in that case, the cannon is equivalent to a piece of scrap metal, and it cannot threaten Guangzhou City at all." The simplest and easiest thing to do is to rely on the superior weapons in our hands to suppress the enemy's artillery three miles away, and if we get close, we will blow it up, instead of relying on the enemy's negligence.

Relying on a sneak attack out of the city is not a way, and there are too many accidents that may occur, which is not enough to fully control the battle situation, and it is too risky to avoid a sneak attack that will not be killed by the Yuan soldiers. Think about it again, discuss it with your subordinates, everyone will talk about it, and brainstorming when you encounter a problem is also a good way. ”

"Yes, General Zhao, I will come up with a feasible way as soon as possible, and I must keep the Yuan army's artillery out."

After the cannon test firing, Boyan's confidence increased greatly, and the generals who were worried all day long, and everyone who wanted to bow their heads to avoid when they saw Boyan, also swept away the gloom, and dared to speak in front of Boyan. The craftsman master, who has always been worried, also let go of his psychological baggage, and the other four 10,000-pound cannons also started casting at the same time.

During this time, the Song army did not react, and Boyan also tried his best to restrain his subordinates, as much as possible to prevent them from going out of the camp to avoid chaos at this critical time, which affected the plan to cast cannons.

Suddenly, in the early morning of one day, the scouts of the Song army quietly went out of the city by night, and hundreds of fast horses rushed to the forest between the camp of the Yuan army and the Yuan army, and set a monstrous fire.

At this time, although it is a rainy season, it is also a hot day with dry weather, and this lush forest can not withstand the burning of fire oil pine, and it has been burning from the middle of the night. By the time the sun was high, the woods had become black and white, and the Yuan army only sent a few patrols at night to observe the fire, and there was no intention of putting out the fire.

Seeing that the woods three miles away were burned clean, Liu Changhai put down his snack slightly, so that his vision became very broad, as long as the cannons in the Yuan army camp were launched, it would be difficult to hide from the reconnaissance soldiers on the Guangzhou watchtower.

Liu Changhai and his subordinates discussed several times and decided to adjust the tactical distribution of the Hongyi cannons, and the eighty-eight cannons of the largest caliber were all concentrated and deployed to the north city gate. With the ultra-long range of these eighty-eight Hongyi cannons, to deal with the cannons cast by the Yuan army, anyway, your cannons are extremely huge, and slow movement is simply a target.

After the charge of these Hongyi cannons is increased by fifty percent, the firing range can easily reach four or five miles, but it will reduce the life of the entire cannon, but at this critical time, it will not take care of so much.

With more than 80 cannons for special prevention, Liu Changhai's investment was large enough, and since then, the large-caliber Hongyi cannon has never fired a single cannon, just waiting for the legendary 10,000-jin cannon to appear to fight a cannon to cannon battle.

The fifth 10,000-jin cannon was finally completed, and it only needed to polish the burrs in the barrel for two days, and then put it on the newly made iron-wood gun carriage, which could be driven outside the city of Guangzhou to be used in actual combat.

"Prime Minister, Prime Minister, one hundred and fifty carts of pig iron collected by Xiangyang were delivered last night, the number is far more than 50,000 catties, and the cannon can be cast immediately!"

Ali Hague held a letter sealed with fire paint in his hand, and bent down to hand it to Boyan.

"I also brought a handwritten letter from the Great Khan."
