King of German Mercenaries

During a cross-country training, Marin was there to scout the terrain, but found that the distance that the human eye can see is limited, and it is impossible to see clearly at a distance. So, Marin remembered the telescope...

The telescope was only invented at the beginning of the 17th century, and there are still more than 100 years left. Marin had to find a way to make an "invention"...

Of course, as an advanced technology, and it is a very strategic advanced technology, Marin is not willing to let others know the existence of the telescope. So, he went to the optical shop in Robach, and found a craftsman in the shop to polish a batch of circular concave lenses of the same size. Then, he rode to another town, found a local optical shop, and asked the glasses craftsman in this shop to polish a batch of convex lenses (magnifying glasses) of similar specifications for him.

Then, he went to Vienna and found a craftsman who was good at making wooden handicrafts and made a batch of wooden tubes for him. The front and rear ends of the wooden barrel are detachable spiral card holders, which can fix the polished lenses.

Of course, in order to hide the lens, there is a length of wooden tube in front of the deck, so that people can't see the glass inside. If you don't pay attention, when Marin looks into the distance with the telescope, others think Marin is looking through a wooden tube.

However, what makes Marin depressed is that the quality of glass in this era does not seem to be good. General glass, some green. This is because the iron ions in the glass are not removed, so the transparency of the glass is not very good. The earlier optical glass, lead glass, seems to have appeared in England in the 17th century.

Therefore, Marin can be sure that the telescope of this era will not look too far. Because the clarity of the glass is not enough...

Sure enough, after Marin got the goods a few days later, he assembled the telescope by himself, and he could draw a long wooden tube and adjust the focal length. However, no matter how Marin adjusted, the telescopic distance of the telescope was no more than 5 kilometers. Farther away, it starts to blur. Even at a distance of 5 kilometers, it can only be discerned roughly, but cannot be seen clearly. Of course, this is used to detect the enemy's situation, which is much better than seeing it with the naked eye.

After assembling the two telescopes, Marin bought two wooden boxes and locked the telescopes. Only he had the key and no one else could open it. Even if there are a few Kahns, they don't know what this is.

After that, in order to train Schwartz (in fact, Marin decided to be lazy and let Schwartz do some daily work instead of him), Marin organized several group confrontations. The confrontation was mainly carried out in the mountains, and Marin also took out the mountain ambush tactics commonly used in the East. It's just that he didn't dare to use the trick of throwing rocks down the mountain, because that would kill people.

Schwartz took people hard, made a long detour carefully, and then quietly touched the camp guarded by Marin. But what he didn't know was that at the height of the camp, Marin had already used a telescope to figure out the deployment and marching direction of his troops from 5 kilometers away, and made corresponding adjustments.

When Schwartz's 50 people touched the vicinity of the camp, they directly faced the traps and encirclements set by Marimbu...

Others didn't understand it, but Kohler, who didn't participate in the war, seemed to understand a little - it seemed that Marin could make corresponding subordinates, which had something to do with the two cylinders he locked in the box. However, as a servant, he is not easy to inquire at will, nor can he do so. The depressed Schwartz did not understand why Marin was able to "predict the enemy's opportunities." Then, Schwartz adored Marin more and more...

After a few drills, Marin seemed to notice that Kohler noticed the cylinder in his hand. Therefore, he felt that the cylinder in his hand seemed to be too conspicuous.

So, he found craftsmen again, customized smaller lenses and smaller and more inconspicuous cylinders, and assembled a small telescope again. This kind of telescope is so small that Marin can cover most of it with two hands, but it can also reach an observation distance of 5 kilometers. When Marin stood at a high place and looked into the distance with a telescope, others saw Marin's two hands in front of him.

He thought that his hands were used to block the sun... But in fact, he was holding a small cylinder in both hands...

In fact, the telescope is the most useful thing for scouts. As the head coach, Marin can observe the enemy's formation before the battle, but it is impossible to go out to investigate often (there are also coaches who investigate in person, but the end is generally not good. For example, Li Zicheng went out to investigate and was KOed by an unknown landlord. Washington personally investigated. , and was almost sniped by Colonel Ferguson...). So, after thinking about it, he decided to develop the squire Sauer into a scout...

The reason why Sauer was chosen was because the Sauer family were their own serfs and were more reliable than outsiders. Moreover, Sauer's character is very calm and his mind is not bad. From his recommendation of Schwartz, Sauer is also a bit wise. At least he can see people. Moreover, Sauer's eyesight is also good. What's more, when hunting before, Sauer often served as the task of reconnaissance, and he had some experience in this. He was able to come back and report the location without disturbing the deer or boars, proving he was well suited for reconnaissance.

Moreover, in this era, scouts often have to get close to reconnaissance, which is very dangerous. If you are not careful, you will be found and hunted by enemy sentinels.

But after having a telescope, the scout does not need to approach the opponent's camp, just find a high point a few kilometers away, and pull out the telescope to do it.

In the days when telescopes weren't popular, even the best-sighted people had to come within a kilometer to get some important data. Ordinary people even have to approach within a few hundred meters to see clearly. Therefore, people in this era, even if they are anti-reconnaissance, will not be more than 1 km away.

Therefore, as the first group of people to use telescopes to investigate, under normal circumstances, Sauer's safety can still be guaranteed.

Afterwards, Marin and Sauer had a private exchange. Marin tested Sauer's loyalty and found it to be fine. Then he made Sauer swear that he would never let anyone know about the telescope. Moreover, every time Sauer goes out to investigate, he can only come to him to collect the telescope. Usually, Sauer's telescope is to be locked in Marin's box.

Not only that, Marin also asked that in front of others, Sauer must not use the telescope to avoid being seen as the problem.

Sauer didn't care at first, but when he got the telescope, he was really surprised. The first time he used the telescope, he was so frightened that he nearly dropped it.

"This... this is amazing!" Sauer was shocked.

"Okay, Sauer, remember, never reveal the secrets of the telescope to anyone! Including your relatives!"

"Yes, sir!"

"Also, don't drink too much alcohol in the future. It's easy to talk nonsense when you're drunk."

"Yes!"

"Okay, let's go!"

Over the next few days, Marin assigned Sauer several reconnaissance missions, taught him how to conceal himself, and gave him a camouflage reconnaissance outfit.

Sauer has been trained to complete the task better each time. In fact, the difficulty of this kind of task is also very low. If you use a telescope to peek a few kilometers away, who will not do such a thing. The key is to choose a suitable location to avoid being discovered by the other party. Moreover, reconnaissance also requires patience. Fortunately, Sauer is a very patient man. If he was as quick-tempered as Kahn, he would definitely not have the patience to sit there and slowly count the number of each other, the number of animals, and the entry and exit of carriages and horses.

Of course, this involves the knowledge of reasoning and calculus, and Sauer certainly does not have that level. What Sauer can do at present is to estimate the number of people on the other side through the house/tent, and infer how many pots the other side has by using the amount of smoke that rises when cooking, so as to simply infer the number of people who eat each other...

These are basic truths, and Westerners in this era prefer to confront hardships, and at this time they will never come up with any strategy of "reducing the fire and attracting the enemy". This estimate is relatively accurate.

In addition, Marin also emphasized that Sauer should strengthen the observation and estimation of the location of the enemy's grain storage. In the Middle Ages, Europeans would not have figured out a way to disguise military rations with sand to stabilize people's hearts. Therefore, investigating the opponent's grain reserves is also conducive to estimating the opponent's military morale (the military morale is stable when the food is sufficient), and it can even facilitate the destruction of the opponent's grain and grass...
