Marin didn't know the specific attack time of the Saxon army. Although he estimated that it would be after the autumn harvest, he was not sure. If the old and cunning Duke of Saxony had a whim and launched an attack in advance, it would be a tragedy if Marin was unprepared.
Therefore, Marin decided to send spies to Dresden, the capital of the Principality of Saxony, to investigate the movements of the Principality of Saxony. In fact, this job is very simple. You don't need to break into the top management of Saxony, you just need to observe the daily life in Dresden.
If the Saxons were going to attack, they would have to muster at least ten thousand troops. And gathering more than 10,000 people obviously won't be silent. Among other things, the transfer of food alone will be very frequent. The preparation of other materials will also cause market turmoil.
Therefore, Marin intends to ask Kohler to send two grain merchants to Dresden from the "North Sea Chamber of Commerce" like a leather bag company to inquire about the news. Once the Dresden grain market finds an abnormality, he will send someone to report the situation.
Of course, this is only one of the early warning methods. In addition, defense on the homeland is also very important. The Saxon army is obviously not here for tourism. Wherever the army passed by, there must be chickens flying around. Moreover, the army in the Middle Ages had the bad habit of robbing the people of food. Every time a war broke out, the number of people who died because of the lack of food far exceeded the number of people slaughtered by the army. In the "Thirty Years' War" that broke out in the 17th century, millions of people died in Germany. Among them, more than half died due to lack of food. There is also a large part of the death caused by the plague. Only a small number were killed by lawless soldiers.
Marin can bring most of the food into the city, but he always has to leave a stutter for the people in the manor outside the city. But if the food is scattered in the manor, it is easy to be robbed by the passing Saxon army.
Before, Marin thought about digging a cellar. But, later, he remembered that the soldiers of this era are definitely veterans in looting property. The common people are not stupid, and the belongings at home will definitely be buried. Therefore, in order to search for more property, many veteran soldiers have trained a pair of "golden eyes" to specialize in searching for hidden compartments and basements... The more experienced soldiers are, the more proficient they are...
Therefore, Marin decided to set up several bunkers across the country, which not only have a defensive function, but also can protect and store food.
Moreover, these bunkers also serve as beacon towers...
In this day and age, there are no mobile phones, no telephones and no telegraphs. Therefore, it is difficult to determine the whereabouts of the enemy. However, the ancient Chinese ancestors cleverly invented the alarm mechanism of the beacon tower.
Beacon towers set off beacon smoke during the day and light a fire at night, sending a very clear signal to neighboring beacon towers. Then, one after another, until it was passed to the military camps and various towns in the rear.
Generally speaking, according to the Tang law, there is one beacon tower every 30 miles, but they are all built on high mountains so that they can be seen from a distance. However, East Frisia is full of plains, with at most a few small slopes. Therefore, the distance between beacon towers must not be set that far.
For this reason, Marin decided to set up a bunker every 10 kilometers. The bunker is both a fortification and a place to store food. The top floor of the bunker can also be used as a beacon tower for early warning...
Marin actually learned this trick from the devils in the movie. At the beginning, the devils used a large number of bunkers to blockade the base areas, and caused the Eighth Route Army to fall into serious difficulties. They were once oppressed and retreated to the mountains. Even top leaders like Zuo Da's chief of staff were unfortunately killed. Therefore, this method is very powerful.
Of course, Marin built the bunker not to suppress the common people, but to guard against foreign enemies. The devil's bunker is still worth learning. Because the bunker's defense ability is good. In particular, after the moat was dug, the only connection between the bunker and the outside world was the suspension bridge. In this way, if the enemy wants to besiege the bunker, they must first overcome the river around the bunker. This difficulty is not small. The guerrillas of later generations were able to quickly capture the bunkers because they had explosive weapons such as blasting tubes and explosive kits. Moreover, those are the dynamite packs of the 20th century, all of which are smokeless gunpowder, which is much more powerful than black gunpowder.
As far as this era is concerned, if a blockhouse is built, it will definitely take a long time for the Saxon army, which mainly uses cold weapons, to conquer a strong blockhouse with a moat.
And Marin's intention to build the bunker was to prevent the Saxon army from easily grabbing food, nothing more. Because, as long as Marin is given enough time, he can lead the main force to defeat the Saxon army. Therefore, the function of the bunker is only to delay time.
Before Marin entered the Counties of East Frisia, East Frisia was a country where almost all the people were soldiers. This is because East Frisia is relatively poor and cannot afford regular mercenaries. Therefore, the Sexner family had no choice but to turn their minds on the serfs. Whenever there was a war, the serfs would be armed and dragged into the city to defend the city.
However, the militias served by these serfs could only be used to defend the city. Let them face off against professional mercenaries in the wild, and they will definitely lose. But it is used to defend the city, but it can rely on the strong city wall to play a role.
Similarly, if the Saxon army invades. Those militiamen who had no time to retreat into the city could hide in the bunkers in their respective manors to fight against the besieging Saxon army. The bunker has strong protection and can last for a long time. Moreover, the Saxon army came here not to conquer the bunker, but to defeat Marin. When there are more important things to do, the Saxon army will generally not fight a few rural bunkers, but will choose to give up temporarily. After all, it is very stupid to leave the army to fight against a few rural bunkers.
The bunkers can not only resist the enemy's attack for a certain period of time, but also release beacons (European wars usually take place in the daytime, so the possibility of releasing beacons is the greatest), warning the bunkers in the distance. Then, through a relay between the bunkers, the warning signal was transmitted to Aurich. In this way, Marin has enough time to make an appropriate response. By the time the enemy army arrives, the preparations have already been completed on my side.
Originally, Marin planned to build the bunker into a larger dock. However, Marin remembered that in the history of China, many tyrants used Wubao to fight against the imperial court. Therefore, Marin finally decided to build a much smaller bunker. Bunkers are small, cheap to build, and don't take long. Moreover, because of the small scale, when a local rebellion occurs, it is impossible for all the rebels to retreat into small buildings like bunkers. But Wubao is different. When a rebellion occurs, Wubao can accommodate a lot of people, making it difficult for the ruler to deal with it.
Therefore, the establishment of a bunker can not only play its due role, but also prevent local forces from using it to fight against Marin himself. After all, the Saxon army was passing by and had no time to pay attention to the bunker. Marin is the ruler, but he has enough time to besiege the bunker. Therefore, bunkers are very difficult to use against rulers. Even if it is useful for a while, it will definitely be suppressed in the end.
After making up his mind, Marin signed an order to build bunkers and beacon towers all over the country, building one every ten kilometers...
In fact, the county of East Frisia is very small, only more than 3,000 square kilometers. Therefore, in total, Marin only needs to build dozens of bunkers. However, the early warning ability for foreign enemy invasion has been greatly improved. After the establishment of the bunker + beacon system, no matter which enemy country it is, it is impossible to achieve the goal of sneak attacking East Frisia.
Just like the last time Marin attacked East Friesland last time, if East Friesland had a beacon system at that time, once Emden set off a wolf smoke, Aurich would receive a warning within half a day. Not to mention whether they can send troops to rescue Emden, at least, they won't be tricked by Marin to open the city gate.
Not only that, but with the bunker, Marin can strengthen his control over various places. As long as a dozen standing army soldiers are stationed in each bunker, Marin can thoroughly monitor the situation around the bunker. If there are signs of rebellion somewhere, the news can be quickly learned by Marin, and a wolf smoke can solve the problem.
In short, the establishment of the bunker + beacon system has raised the military security of East Frisia to a very high level. At least, as soon as there is a disturbance on the border, the alarm can be sent to Aurich quickly, giving Marin enough time to respond and avoid being successfully attacked. At the same time, the existence of the bunker can also enable Marin to control the rural areas to a high degree. No matter what troubles arise, they can be conveyed to myself by the soldiers of the standing army stationed in the bunkers everywhere...
