The map surveying and mapping of Beihai Country is different from the surveyors of other countries in this era. For example, Marin introduced the contour marking method that only appeared in the 18th century. In this way, the map is more intuitive and provides more detailed information to the army commander.
In this era, because there is no contour marking technology, maps of other countries can only mark the difference between plains, rivers and mountains. However, it is not clear how high the mountain is. At most, with some brief introductions. For example-this mountain is very high, this mountain is neither high nor short, this mountain is very short... But the specific height depends on the officers who look at the picture and use their imagination. If the imagination is wrong, it will be over...
However, because it is sneaking into other countries to survey and map. Therefore, many large-scale surveying and mapping instruments invented by Beihai State cannot be carried. Even if you bring it over, you can't use it. As a result, the spy door can only carry small surveying and mapping equipment such as short rulers and protractors. For example, when measuring the height of a mountain slope, the only way to measure the height of the mountain can be through the flagpole shadow method. Of course, the **** of the lower **** will also be marked. This is very important because it relates to whether you can send troops to rush up.
In addition, because it is a deep survey and mapping in other countries, the height of the mountain **** is not the measured altitude, but the height of the relatively flat ground. Measuring altitude requires measuring atmospheric pressure and calculating gravity acceleration. Although Marin provided a lot of data, he could not give a particularly accurate figure for the detailed value of the acceleration of gravity. Therefore, sometimes there will be a large error in the calculation, resulting in an error in the altitude calculation.
But for marching and fighting, the absolute altitude is not very important. Military maps mainly consider the impact of terrain differences on military marches. Therefore, spies only need to use simple and easy-to-carry measuring tools to measure the height of the hillside relative to the nearby plain.
Then, draw the contour line and mark the **** angle and whether it is suitable for washing up the mountain. Of course, whether the mountain is a stone mountain or a soil mountain must also be marked. Because the earth mountain can collapse, while the stone mountain is difficult.
In addition, the depth of the river is also an important surveying project. After all, Marin wanted to use ships to transport grain and grass deep inland. There is also the wind direction and wind force in the river area, as well as the seasonality of the wind. After all, the boats of this era are mainly sailboats. This requires a long period of observation, as well as introductions from locals. But asking locals directly about such professional questions will be suspected of motives. Therefore, we can only inquire round and round.
In addition to the wind information, fighting in the Russian region, the frozen world on the river must also be grasped clearly. If the world is wrong and the huge fleet is frozen on the river, it would be miserable. There are several months of winter in Russia, and the ship is frozen in the river, which is simply a target for the Muscovites.
Obviously, it was because Napoleon's army did not consider these details thoroughly, which eventually led to all losses. And because of the failures of Napoleon and Mustache, Marin did not dare to relax.
Moreover, Marin never thought of occupying this side for a long time. Mainly, the defeats of Napoleon and Moustache are really frightening. Therefore, despite his eyes on the extremely large population of the Grand Duchy of Moscow and the vast resources of the country, Marin did not dare to give birth to the idea of fully occupying and controlling the Grand Duchy of Moscow. It's not that I can't beat the Moscow army, but the weather...
Therefore, for Moscow, Marin can only give birth to the idea of looting the population, rather than directly annexing it. Moreover, even if you really want to annex, it is not the time right now. At least, until the annexation of England and the settlement of the French and domestic princes' threats, Marin was unable to covet there.
...
However, how to send spies to sneak into the Grand Duchy of Moscow, Marin summoned Kohler and Kohler's intelligence officials to discuss.
But the Grand Duchy of Moscow is too far away, and everyone is not as familiar with it as Marin. In the beginning, Marin was planning to send someone to sell alcohol inside the Grand Duchy of Moscow. After all, Maozi is a good spirit, which is world-famous.
However, intelligence officials said-this idea is okay, but it can only work in urban areas. Because, in the vast rural areas of the Grand Duchy of Moscow, people do not like to drink hard liquor, but can't afford it.
If you go with Erguotou, they can only be greedy. Or, just draw a knife to grab it. Because they have no money...
Not to mention those serfs, even the rich households in ordinary small villages are relatively poor. According to the information returned by some spies sent to the Grand Duchy of Moscow not long after, in many remote villages in the Grand Duchy of Moscow, the lives of wealthy families may not be as good as the serfs in the manor under the name of Marin.
The serfs in the manor under Marin's name are all black bread. The bread has a high proportion of rye flour, and the grass chaff is almost invisible. At this time, wealthy households in villages in remote areas of the Grand Duchy of Moscow still had a high proportion of brown bread and wild vegetables. That is to say, there are a lot of wild vegetables in the forests of Eastern Europe. Adding to the occasional game to get some game, it's still pretty good.
But a very strange phenomenon in the Grand Duchy of Moscow in this era is that there are many wild animals, but people lack the weapons to deal with them.
Because of the backward production technology, the peasants of the Grand Duchy of Moscow let alone iron weapons, even iron farm tools are severely lacking.
It is said that in this era, the price of salt in Eastern Europe is high. In fact, ironware is the most expensive commodity in the Ross area in this era. Its price is more expensive than salt.
In the impression of later generations, Russia seems to be rich in minerals, and there is no shortage of coal and iron at all. But in fact, in this era, the Grand Duchy of Moscow is short of coal and iron.
For example, the Kursk region, which is rich in coal and iron resources in later generations, still belongs to the border area with the Crimean Khanate. Even if coal and iron resources were discovered and the steel industry started, they would be snatched by the brutal Crimean Khanate. Because the Crimeans also lack iron!
As for the Ural coal and iron production areas, they still belonged to the Kazan Khanate and the Siberian Khanate at this time. Even if the Grand Duchy of Moscow knew that there was coal and iron, there was nothing it could do. What's more, they don't know now.
Therefore, it is embarrassing that the current ironware of the Grand Duchy of Moscow relies on imports and is expensive. Even if there are many wild animals in the territory, they don't have enough weapons to hunt them down. In particular, the people lack iron weapons to deal with wild animals.
Even if Vasily III wanted to attack Smolensk and lacked weapons, he had to entrust the Teutonic State to help purchase from Western Europe.
Of course, it cannot be said that the people do not have the ability to hunt wild animals. Ordinary hunters can use traps to hunt wild animals. In addition, even the arrows made of stone tools can be used to hunt small animals and larger deer.
However, animals with thick skins such as wild boars and bears are never dared to provoke them. Unless these thick-skinned beasts fell into the trap, ordinary people would not dare to hit their minds.
In fact, the first spies sent to the Grand Duchy of Moscow suggested selling matchlock guns to the villages of the Grand Duchy of Moscow. In this way, these hunters can easily deal with beasts such as bears, wild boars and wild wolves. Then, after selling matchlock guns and ammunition at high prices, they can also purchase animal skins from local hunters who buy matchlock guns at low prices.
It can be said that this is a great deal of killing two birds with one stone! But Marin directly rejected it, why? Because Marin worried that these matchlock guns would fall into the hands of the official hands of the Grand Duchy of Moscow. After all, the Grand Duke gave an order to confiscate the matchlock guns of those hunters, which is a matter of one sentence.
And those fine matchlocks made by the North Sea countries, if they were obtained by the Moscow Grand Duke’s army, might harm the army led by Marin in the future. Perhaps, Marin himself, the man who led the troops himself, would also suffer.
Therefore, Ma Lin would rather let this profitable and good business not do it, and would not cause trouble for his future military operations.
However, if you have a business, you have to do it. Moreover, only with good business projects can the spies be successfully sent into the territory of the Grand Duchy of Moscow in the name of merchants.
The merchant who buys fur is a very reasonable identity. But ordinary people in the Grand Duchy of Moscow lack weapons to deal with beasts. What should be done? Can't sell matchlock guns to them, isn't it, sell bows and crossbows?
Marin thought for a while, but gave up. After all, a sophisticated crossbow, in this era, is actually no worse than a musket. Even, in many respects, it is better than the musket. And if it is a crossbow that can shoot bears and wild boars, it can also pose a huge threat to the soldiers of the North Sea country...
Guns don’t work, UU reading www.uukanshu. Com bows and crossbows won’t work either. Do you really want the Orion in Moscow to use stone weapons to take risks? Others have to be happy... and if they use the fur of a beast caught with a trap, they may not necessarily sell it to you...
Thinking about it, Marin suddenly remembered a video he had seen in his previous life. It was a video of African black uncles hunting elephants with a javelin...
Uncle Hei used primitive javelins to pierce the thick-skinned elephants into hedgehogs, which was extremely spectacular. Elephants with such thick skins don't have a low javelin, and bears and wild boars are not immune. What's more, it's still a javelin head made of iron. Moreover, for the army, those javelins are not a threat. Because, Marin remembers, it was said in previous life books that the range of the heavy javelin was about 27 meters. The range of the light javelin is 50 meters. For this short-range weapon, even if it is taken away by the authorities of the Grand Duchy of Moscow, it will not pose much threat. After all, let alone single-headed bullets, even ordinary bows and arrows can abuse the javelin.
Therefore, intelligence officials such as Marin and Kohler formulated a plan to send spies pretending to be fur merchants to go deep into the heart of the Grand Duchy of Moscow, purchasing furs, and selling the iron spearheads of heavy javelins.
The javelin head is easy to carry, not attached to the wooden handle, and occupies a small volume. Moreover, even if they are found by the official of the Grand Duchy of Moscow, they will be taken away at most without prohibiting them from entering the Grand Duchy of Moscow. Why? Because the official of the Grand Duchy of Moscow also lacks iron tools. Big deal, you can promise to sell iron spear heads to the court of the Grand Duchy of Moscow. In this way, it will surely be able to exchange permits for activities in various parts of Moscow. As long as he can smoothly enter the inland of the Grand Duchy of Moscow and survey and map topographical maps, Marin doesn't mind giving the Grand Duchy of Moscow some sweetness...
