On the New Year of the third year of Yuangui, the Military Industry Department of Lanxiang Huaju presented Yu Qiuping with a New Year's gift that made Yu Qiuping ecstatic - a successfully imitated three-pound cannon.
After nearly a year of hard work, Lan Xianghua's Military Industry Department finally succeeded in replicating the first large cannon. Since Tokiwabei hardly expanded the army in one year, the production of iron cannons, weapons, long guns and short knives were gradually slowed down.
Slowly, the Military Industry Department invested nearly 80% of its strength into the imitation of large tubes; and the brothers brought back by Itami Yasuki also shared the drawings and experiences they knew with each other; in addition, Yu Qiuping did not hesitate to spend a lot of money.
The three-door cylinder they bought was used as a test product and a steady stream of experimental funds were provided, and the Military Industry Department finally succeeded.
During this year, they made and discarded countless grinding tools, wasted countless copper and iron metals, and consumed almost as much money as the annual cost of thousands of feet. Yu Qiuping stood up to the Congress and the Sena clan.
They faced huge pressure from justice and supported them in carrying out the experiment against all objections, and finally succeeded.
However, what was placed in front of Yu Qiuping was still just a pitiful three-pounder with little power - this was the only result of the Military Industry Department's efforts for a year. Its range was about 300 meters, and it only fired solid iron balls.
It is difficult for artillery shells to have any lethal effect on buildings made of earth and stone. If Lan Xianghua had not repeatedly assured Congress and Sena Shiyoshi that with the experience and data of the first cannon casting, cannon casting would be faster and faster in the future.
, the cost will become less and less, and the cannon casting plan of the Military Industry Department will almost be rejected.
However, this three-pound gun became Yu Qiuping's treasure. He asked the Military Industry Department to build a small gun carriage for this gun, which was pulled by four horses. He also generously equipped it with a man
There is an artillery crew of about 20 people. There are both gunners here - they are also training hard day and night in artillery skills to improve accuracy and firing speed, just like when Yu Qiuping trained iron gunners before. There are also coachmen, shield soldiers, and loaders.
Hands and many other auxiliary arms.
However, as the gunners practiced, Yu Qiuping discovered that something was wrong. No matter how hard they practiced, their level improvement was always very slow, less than half of the improvement rate of the iron gunners back then. Yu Qiuping and Itami Yasukyo had an exchange
After a while, I finally realized the problem. No matter how difficult the iron cannon is, you just need to aim accurately and hit people in a straight line. But the big cannon is different. The trajectory of the projectile fired from the big cannon is a parabola instead of a straight line. Shooting with a big cannon
The angle of elevation at the time, how much gunpowder is loaded, and the estimation of the distance between the enemy and ourselves cannot be learned overnight. Yu Qiuping saw two gunners with his own eyes. Even if they practiced very hard, their sense of distance was not good. Li Mingming 100
When it's about 500 meters away, they think it's 60 meters. If it's about 500 meters away, they think it's 300 meters. If they can't even estimate the distance accurately, how can they be expected to calculate the angle of the parabola?
Only then did Yu Qiuping realize: Artillery is a technical branch after all, and there are special artillery academies in Europe for training. It is unrealistic to expect artillery to be as easy to train as infantry and iron gunners. So, Yu Qiuping temporarily stopped the artillery training blindly.
Instead, he and Takenaka Shigeharu led a group of smarter staff officers to try to compile an artillery training manual.
Yu Qiuping first tried to work out a method of estimating distance - it was not easy. Because artillery requires accurate parabolic shooting, the distance must be accurately grasped. However, after all, Yu Qiuping is also a student with a systematic mathematics education.
After thinking hard for several days, he stumbled around and found a set of thumb measuring methods that were very similar to the European artillery ranging method.
Distance method. This method is based on trigonometric functions (or similar triangles) and calculates the distance between itself and the target by establishing two similar triangles.
The rangefinder raises one of his thumbs and uses one eye to observe a distant target with a known approximate height through the upper and lower ends of the first knuckle of the thumb (such as the opponent's ashigaru - the height is generally 1.55 meters)
left and right, or some trees or hills that have been measured in advance). By feeling the height ratio between the target and your thumb, and then measuring it based on the distance between your thumb and your eyes, you can calculate the approximate distance between the target and yourself.
The method proposed by Yu Qiuping surprised the members of the staff and artillery crew. They had never thought that there was a way to calculate the distance step by step in the air. They originally thought that they wanted to know the distance.
The length can only be measured with a ruler.
However, although Yu Qiuping came up with a method, this calculation method was too difficult for the uneducated Ashigaru. No member of the artillery crew could learn these things. Yu Qiuping had no choice but to
They had no choice but to hold an exam for the entire Yuqiu family, trying to select some people with more mathematical talent to be the gunners and rangefinders of the artillery team.
To his surprise, the one with the best test score turned out to be Naoe Seigenmaru! Neither Yu Qiuping nor Naoe Tadayei noticed that this child had such a good talent in mathematics. Yu Qiuping would usually give Yu Qiu Ping
Shang, Yu Qiuyou, Yu Qiuguang, Husong, Naoe Seigenmaru and others take some basic arithmetic courses, but Naoe Seigenmaru's performance has never been outstanding. I don't know why he did so well in the exam this time, compared to the second place one.
The Kinki Ashigaru named Senju Ounari is more than ten points taller.
However, Naoe Seigenmaru has not yet entered the military service. He is only 10 years old this year, and it is still too early to join the army. However, after consulting Naoe Tadayei, Naoe Tadayei strongly supported Yu Qiuping's inclusion of Naoe Seigenmaru.
The artillery crew. He felt that since this child was so old, it was time for him to gain experience and make some contribution to the Yu Qiu family. So Yu Qiuping no longer refused and asked Naoe Seigenmaru to serve as the deputy to the gunner Senju Omanari.
Yu Qiuping personally held classes to teach the skills of trigonometric functions to those with top ten test scores.
After selecting the new gun crew members, Yu Qiuping took them to measure the relationship between the large tube elements, the range and the amount of gunpowder, the relationship between the elevation angle and the impact point, the combination of elevation angle, range, and gunpowder loading...
After another long test, a large amount of data was measured. After the hard work of Yu Qiuping and the artillery crew members, a three-pound gun training manual was finally compiled, and artillery training can also be embarked on.
On track. Lan Xiang Huaju's Military Industry Department also began to continue to produce more large tubes to distribute to the troops.

On February 13th of the third year of Yuangui (1572), Yu Qiuping suddenly gathered troops in his territory and rushed to send troops to Nankawa before the end of spring plowing. Oda Nobunaga sent people to instruct Yu Qiuping before and after the Spring Plowing to finish the spring plowing.
Attack Gaowu City in advance. Because one-third of Yu Qiuping's army are standing troops (that is, combat soldiers). However, only one-seventh and one-eighth of the Sanhao family's troops are standing troops, and the remaining
Those under the banner are all militiamen who need to participate in spring plowing and autumn harvest, and will only be mobilized during slack times. Yu Qiuping recruits auxiliary troops to launch attacks during spring plowing. Although it will have a considerable impact on the agriculture in the territory, it will not have a small impact on the Sanhao family.
But it will be even greater. Such a method can damage oneself by eight hundred and injure the enemy by one thousand. Oda Nobunaga allowed his subordinates to use it without any psychological burden.
But Yu Qiuping had no choice but to obey the order.
Yu Qiuping's dispatch of troops made the businessmen in the House of Commons very dissatisfied - deploying troops during the busy farming season means that this year's harvest will be affected, and the national treasury will be under pressure. And the people may live in poverty due to insufficient harvest, reducing their purchasing power.
, also brought trouble to merchants' shops. What's more serious is that the labor required for a large number of factories opened by merchants only comes during the slack season. If Yu Qiuping deploys men to start a war, many laborers will have to stay.
If there is a vacancy in the territory to recruit soldiers to complete the spring plowing of the territory, they will not be able to work here - this will have a huge impact on the factory. However, the previous constitution did not restrict Yu Qiuping's right to send troops. At the legal level
Yes, Yu Qiuping can send troops whenever he wants.
The House of Commons then decided to remedy the situation and formulated a new law: If Yu Qiuping wants to carry out large-scale military activities during spring plowing, autumn harvest and other busy farming seasons, it must be approved by a majority vote of the parliament. After hearing about this bill, the Yuqiu family
He was furious - not only did the Congress hold the money bag, but now it also wanted to interfere with the military command of the Yuqiu family?
However, Yu Qiuping also offended the small wealthy families this time by gathering troops during the busy farming season. Although their income is no longer related to the harvest of the territory, after all, it is the land that they have passed down from generation to generation. Therefore, in the formation of the small wealthy families,
In the House of Lords, except for the four small wealthy families in Meinong who voted against it, everyone else approved the resolution.
However, Takamasa Hatakeyama stood up again at a critical moment - he pointed out that the bill of Congress was contrary to the requirement in the constitution that the military command power belongs to the Uaki family, declared the law unconstitutional, and ordered the House of Commons to revise it. Takamasa Hatakeyama
This move can be said to have saved Yu Qiuping once, because the businessmen wanted to enact the law again, which took a lot of time. After Hatakeyama Takamasa expressed his position, the small wealthy families in Hanoi also tended to follow their Hanoi guardians on the same side.
position and refused to pass this law, which put a lot of pressure on the House of Commons.
While there was internal wrangling in the Congress, Yu Qiuping's military operations were able to launch without any constraints and launched an attack on Nan Hanoi.
It was not that the Sanhao family had not noticed Yu Qiuping gathering troops in the territory, but they did not expect that Yu Qiuping would risk the impact of spring plowing and mobilize the entire army to attack. Because Yu Qiuping has always been a safe and cautious person, and rarely launches decisive attacks.
Surprise attack. They did not know that Ame Qiupei's attack was forcibly promoted by Oda Nobunaga behind the scenes. Miyoshi Choitsu and Miyoshi Masayasu in Takaya Castle were caught off guard and had to follow them to assemble their troops. But after they assembled a group
Before supporting a force capable of competing with the 2,400 troops of Tokiwa Bei and Mei Dabei, the Uakiu Army had already broken through the Yamatogawa defense line and surrounded Takaya Castle.
At this time, the Miyoshi family had not yet been able to assemble all the Minami Kawauchi troops in Takaya Castle, and many people had to scatter in the small town to fight on their own. Under the guidance of Hatakeyama Takamasa, many small wealthy families in Minami Kawachi who had been suppressed by the Miyoshi Army before
They revolted again and cooperated with Yu Qiuping's troops to attack the Sanhao family's stronghold in Nanhanei. Within 10 days, the entire Nanhanei had fallen under Yu Qiuping's control, and Gaowu City became an isolated island. The Sanhao family hurriedly left after the autumn harvest.
They assembled their troops and planned to come to Kinki to fight. Not to be outdone, Oda Nobunaga gathered the largest army that Owari, Mino, Ise and Minami Omi could mobilize to go to Luo, preparing to show off with the Miyoshi family.
Just when Yu Qiuping's Nanhanei strategy was unfolding smoothly, a big net had been opened in secret.
Chapter completed!
