Two flowers bloom and one on each table, just when Li Jiancheng turned on the electric light here and waited for the night to come, Sun Chengzhong on the edge of the Hunhe River on the battlefield in Liaodong also ushered in the darkest moment!

As the sun sets, the smoke in Shenyang rises to half the sky; A muddy river is half muddy and half red, a good battlefield smoke.

Yue Tuo's army and Xu Xianchun confronted them on both sides of the Hunhe River, and the two sides were swords-rattling, as if there must be a bloody battle before sunset!

And this qiē is also certain, looking at the movement on the other side of the river, You Shigong's face became more and more blue, and he said fuckingly: "Fuck it, they actually moved the cannon out of the city!" ”

The cannons on the other side of the river were erected one by one, and You Shigong and Xu Xianchun were both pale! The reality is always worse than imagined, and the opposite side obviously wants to cross the river before dark, whether they run or not, as long as his cavalry crosses the river, they will be killed by their mobility from a long distance. The grenade array is okay for small-scale surprise attacks against large-scale enemy impacts, but it is not good for large territories at all.

Xu Xianchun said to the remaining eight hundred musketeers: "Dig trenches!" ”

Eight hundred people unequivocally took out the sapper shovel and began to dig a pit, You Shigong couldn't understand what he was doing, but Xu Xianchun had taken a class on explosives, which was the first lesson that Li Jiancheng had done when he was preparing for the demolition division. Later developed into the Thermal Weapons Response and Research Institute, the tactics of the trench are not difficult to understand, and it can effectively protect the human body from explosions and shells in open areas.

Therefore, the significance of trenches will at least become the mainstream of the battlefield in the development of hot military forces in the next century. You Shigong looked at the differences between the musketeers digging the pits, and he said, "Is this useful?" ”

Xu Xianchun said: "It's better to have a place to hide than to use your body to resist shells!" ”

Xu Xianchun's words made You Shigong feel enlightened for a while, and his eyes lit up, and he hurriedly ordered others to help. It's much better to have a pit than to stand and be shelled. Besides, he also knew that it was a flat river behind him. Let the cavalry cross the river, they can't run ten miles!

Therefore, only by holding on can there be a glimmer of life, 800 people digging a trench together for half an hour is enough, and digging a pit half a meter deep during training is only given fifteen minutes! The shovel provided by Li Jiancheng is also the design of modern engineering equipment, although there are many failures in the process, but the design of the mechanical principle is very suitable for use. An hour later, two trenches more than half a meter deep for barely more than 2,000 people appeared.

At this time, the cannon on the opposite side was almost ready, and although the people on the opposite side saw the people on the other side of the river digging the earth, they were just amused, could they still dig a tunnel and escape? But when they saw that the trenches were formed, and the people on the opposite side were hiding behind the tunnel, only one head was exposed, Yue Tuo and the others on the other side of the river felt that it was not easy to do this on the other side!

The cannon pushed, and sure enough, there was money that could make the ghost push Mo. Where there is a cannon, there is someone who can fire. When the city of Shenyang was broken, the layout was not deep, and those traitors and lackeys could not be wiped out. Now these people are coming to them with cannons, what an irony!

Without even saying hello, Yue Tuo ordered the cannon to be fired! The cannon roared, and as soon as the cannonball was fired, it flew towards Sun Chengzong and them on the other side of the river!

When it comes to the cannons of the Ming Dynasty, we have to say the more famous red-coated cannons.

The red-coated cannon was first called the 'Hongyi Cannon'. The Hongyi cannon was introduced to China in the late Ming Dynasty and is also known as the red-coated cannon. The so-called "red Yi" is also the red-haired Netherlands. Therefore, many people think that the Hongyi cannon was imported from the Netherlands, but in fact, at that time, the Ming Dynasty called all the front-loading smoothbore cannons imported from the West as the Hongyi cannon, and Ming Dynasty officials often covered these cannons with red cloth, so they were falsely called "red clothes". According to research, only a small number of Hongyi cannons imported by the Ming Dynasty at that time were imported from the Dutch East India Company, and later became hostile to the Dutch due to the Taiwan issue, and most of them were obtained from trading with the Portuguese in Macao. The demand in the Ming Dynasty was huge, and the Portuguese also acted as middlemen to sell British ship-based cannons to China.

The Hongyi cannon does have its advantages in design. Its barrel is long, the wall is very thick, and it is gradually thickened from the muzzle to the tail of the gun, which conforms to the principle of high pressure from high to bottom when gunpowder is burned; There are cylindrical lugs on both sides of the center of gravity of the gun body, and the gun can adjust the firing angle with this axis and change the firing range according to the amount of gunpowder; It is equipped with a crosshair and a light gate, and the trajectory is calculated according to the parabola, which is very accurate. Most of the Hongyi cannons are about 3 meters long, with a caliber of 110-130 mm and a weight of more than 2 tons.

The most prominent advantage of the Hongyi cannon is its range, which is an important part of the performance of heavy artillery, even today. The maximum range of the Ming Dynasty's homemade iron fire gun did not exceed three li, and it was at the risk of exploding; And the general three-thousand-pound Hongyi cannon can easily hit seven or eight miles away, and the historical records can reach as far as ten miles! Ten miles is equivalent to more than five kilometers in modern times, which is quite far away, and there were doubts about this number, but the performance of the same type of artillery in the West proved that this number jù was accurate (at that time, Western European countries already had the concept of territorial waters, and the territorial waters at that time were determined by the range of coastal artillery, and the territorial waters at the end of the 16th century were three nautical miles, about 5.5 kilometers). The long-range Hongyi cannon combined with the flowering shell became the strongest weapon against the Houjin siege at the end of the Ming Dynasty. At that time, the tactics were: lure the cavalry of Houjin into the range of the Hongyi cannon at the head of the city, and then use the flowering shells to concentrate the fire, and the effect was remarkable.

During the Ming Dynasty, the gameplay of cannons in the current era is very advanced and experienced, and during the Jiajin Wanli period, countless cannons were cast for city defense, but they were still wiped out by the Houjin like a broken bamboo, which can only be said to be completely broken from the root of the Ming Dynasty, and the strongest castle was always destroyed from the inside, and the Ming Dynasty was really rotten to the root of the low before it perished.

The shells fell to the ground and exploded, Xu Xianchun buried their heads in the trenches, and when they looked up, there was a crater in the distance, and the first shell was a test angle, so it was not very accurate, but then dozens of artillery pieces on the opposite side fired at Li Jiancheng mercilessly.

The whistling shells fell on Xu Xianchun's position with gunsmoke, and the shells fell on the side of the trench, shaking and exploding to suffocate people, and it was only then that You Shigong thought that if there was no such trench, I am afraid that there would have been heavy casualties and no defense.

But although there were trenches, there were still shells that hit in impartially, this time it was naturally extremely tragic, all in all, the suppression of artillery fire made it difficult for Xu Xianchun and them to show their heads, this situation was naturally caught by Yue Tuo, and he waved his big hand: "Cross the river!"
