Chapter 288： Artillery Ranger II

The surveying and mapping team composed of students from Weiss College followed the first and third battalions southward, and arrived at Fort Byram on June 10 to set up camp.

In order to create pressure on the Kent family as soon as possible, the artillery of the Arda army quickly started shelling.

The artillery directly under the two battalions and an independent artillery company lined up more than 20 artillery pieces and poured firepower directly at Fort Byram.

Sir Valentin, the knight commander of the Kent family, was in charge of commanding the defenders of Fort Byran. He received the news that the Arda army stationed in the north was going south, and immediately sent a fast horse to send a report to Center. Before responding, he must stick to Fort Byram.

After the first Battle of Bidowburg, instead of disbanding, Arda's army occupied the northern part of Emden in one go, which surprised the upper echelons of the Duke of Kent's faction.

Fortunately, the high fortress and deep ditch of Fort Bylan blocked their attempt to occupy the whole of Emden, which made the Duke heave a sigh of relief. If the Kent family lost their hometown, it would be the last bit of loss of face—it has already been lost. It's half of it, it's a shame, okay?

Later, although there was a riot in Arda, the Arda army stationed in Emden did not withdraw. The high-level officials in Center City reassessed Arda's strength—except for the more than 1,000 people who loved Emden. , Greiman still has a large reserve force in the territory.

After entering May, when the "Anti-Usurtor Coalition Army" regrouped, the Gleiman family was missing, and the lords in Center City judged based on this: the remaining troops in Gleiman's hands were due to the previous riots. The impact did not dare to move easily, and he didn't want to spit it out in the north of Emden, so the more than a thousand people stationed in Emden did not move.

It stands to reason that the spies of the Kent family only successfully provoked a riot, and it was quickly quelled. How can they hold back the remaining forces in Arda?

In fact, spies don't need to take huge risks to organize real riots one after another, they only need to use the impact of the first riot.

In the streets and alleys, in taverns and teahouses, some clips that have been "processed" based on facts are inadvertently released, and the spread will become more and more fierce.

Once bitten by a snake for ten years, Huxin Town, which has been afraid of well ropes for ten years and takes "nipping danger in the bud" as its guiding principle, will immediately go to investigate and organize troops to martial law. How do you know it's true before the investigation is clear? fake?

After careful observation for more than half a month, it was confirmed that there was no movement in Arda's army, so the Duke's Mansion formulated a plan: after the arrival of the mercenaries from the south, they should defeat Earl Parker and other lords before Greyman made a move. , and then hit the troops to deal with Graeman.

But what shocked the Duke's mansion was that Graiman had more cards in his hands than expected. After only being caught for a month, he was able to pull out his hand and stab them in the back—landing in Fishtail Town on the upper reaches of the Weiss River.

Of course, the current Sir Valentin has no time to take care of the affairs of Fishtail Town. His current duty is to guard Byram Castle.

This is the place where the Duke's family has lived for generations. If it falls into the hands of the enemy, even if the Duke does not blame him, he will be ashamed to see others, and can only apologize with death.

Sir Van Lundin took part in or the first Battle of Pittburgh, and was impressed by the army of Arda.

At the beginning of being appointed to guard Fort Byram, he still tried to organize troops to conquer the northern part of Emden, but he quickly retreated under the power of Thunder Hammer and Fire Crossbow.

Sir Valentin always believed that he was defeated by the powerful power of thunder hammer and fire crossbow—although the fire crossbow of Arda's army only fired one round before rushing to fight melee with bayonets.

After that, the knight commander made up his mind that as long as Arda's army didn't take the initiative to provoke trouble, he would stay in Fort Byron and not make any moves. With his current strength of less than 2,000 people, he could only do so. Seeking meritorious service, but seeking no faults.

However, he is still very confident in defending the Knight Commander of Fort Byron. As the castle where the heads of the Kent family lived for generations, its defense capabilities are among the best in the entire Northwest Gulf.

After the expansion of the owners of the past generations, the outer wall of the castle is 12 meters high, and the top is 10 meters wide. The boulder was built.

The castle is surrounded by a wide moat, and several deep ditches have been dug outside the moat.

The Arda army once tried to attack Fort Byram, but the moat and ravines prevented the mortars from being deployed close, so they had to use 6-pounder and 12-pounder guns to bombard them, but the effect was not great.

Now they're at it again.

…

Nick and his classmates built a range-finding instrument and are experimenting with the artillerymen on the artillery emplacement.

A beam that is supported on the ground and can be adjusted in height. Both ends of the beam protrude a thin "arm" towards the horizontal front. Viewed from directly above, the "arm" at one end is fixed and perpendicular to the beam, and the other end is vertical to the beam. One end can rotate left and right with the end point of the beam as the center.

"Two points and one line, two points and one line..."

The artillerymen first aimed at the gate of Fort Bairam in the distance with the fixed arm on the left side of the crossbeam, and the aiming was considered when the front and rear ends of the fixed arm coincided with the gate.

"Two o'clock and one line..."

While muttering, the artilleryman moved to the right side of the crossbeam, and gently moved the rotatable movable arm, trying to make its front and rear ends coincide with the city gate.

The length of the beam is one meter, which is the so-called [baseline]. In theory, as long as the angle between the movable arm and the beam is measured, the straight-line distance between the fixed arm and the target can be measured~www.novelhall. com~ But there is a little deviation between reality and theory.

It’s okay to say that the nearby target is relatively easy to measure, but as the target gets farther and farther away, if you move one meter to the left or one meter to the right in the direction of the baseline, there is no change in the angle at all with the naked eye.

"With all due respect, sir, this thing of yours..."

The artilleryman who participated in the test smiled wryly and hesitated to speak.

Nick scratched the back of his head and smiled awkwardly. He calculated carefully, and found that the tangent value of the full 89-degree angle is about 57.28996, and it can measure about 57 meters when the baseline is one meter. 1000 meters, the change of this angle is too...too subtle, and it is impossible to observe with the naked eye and the current crude rotating arm.

It really echoed the words that Earl Greyman taught in the class - a small mistake, a thousand miles away.

Joyce stood behind him and patted Nick on the shoulder: "Don't be discouraged, this method of distance measurement is theoretically feasible, and I believe it can be improved through certain technologies."

He made up some trigonometry-related knowledge on the march, and he had no doubts about Nick's distance-measuring method.

Nick turned his head and said: "Thank you, Mr. Joyce, I think we can increase the accuracy by lengthening the base line at this stage. 1 meter is too short. If it is increased to 15 meters, I think it will be effective for artillery at this stage. In terms of range, its accuracy should be sufficient."

Joyce shook his head: "15 meters, are you sure? It's too inconvenient to make a beam that long?"

"This rangefinder can be disassembled into left and right parts, and the method of two points and one line can also be used to ensure that they are on the same straight line."

"Oh? Let's try!"
