When the army intelligence came up with this conclusion, they themselves honestly couldn't believe it, could those Russians be crazy, they wanted to provoke another war? But with a bunch of factual evidence in front of us, other reasons simply don't make sense.

Previously, the Soviet-German border patrol was mainly carried out by the German border police and Nazi stormtroopers, and only in traffic passes or military fortresses were some regular army units stationed.

This line of demarcation was in the heart of Poland, and there was no reason for the Poles to set up a defensive line here, and there was not even a barbed wire fence on the banks of the river, and anyone could easily cross it with a little preparation.

All the German side can do at this time is to intensify border patrols and make every effort to search for people who have crossed the border in the control area, and find out their true identities, as well as their goals and intentions.

Many of the Polish villages along the border remained, and these peasants eventually moved to the west of Poland and beyond, where there was plenty of agricultural land, many of which lacked the manpower to cultivate because of the loss of population due to the war.

The plan of the German army was to evacuate all ordinary residents of the border in the direction of the German-occupied zone from this dangerous area by the end of the year 41.

The Soviet Red Army was never a liberator, and judging by what they did when they invaded Finland, don't think they won't do it again in Germany. Burning down villages and farmhouses and indiscriminately bombing towns in order to break the will of the local population to resist was a common tactic that was unanimously endorsed by the Red Army.

Clausewitz's theory of war is also very clear, war is the maximum use of violence, and finally force the other side to obey his own will. To put it bluntly, it's all you can, until you kneel down and call Daddy.

International war laws and the like are only binding on the weak, and rookies will need referees when they peck each other, but when lions and tigers fight, others only worry about whether they will harm the pond fish, and who cares whether they use claws or teeth.

After September '40, the Wehrmacht began to carry out major internal adjustments. The field forces on the Western Front gradually moved to the Eastern Front, and in order to avoid triggering an overreaction from the Soviet Union, the troops were concentrated mainly in the Eastern Province, that is, in the territory of the original Czech Republic and Austria. The German troops stationed in central and eastern Poland have also begun to move to the western part of Poland, and these units will return to Germany to be reorganized, replace obsolete weapons and equipment, and at the same time start training in new tactics.

The base of these garrisons themselves is not bad, the main problem is that there are too many new recruits in the establishment and the weapons used are relatively old.

The northern section of the German army's eastern defense line was built on the Vistula River, starting from Gdansk at the mouth of the sea, crossing the entire territory of Poland, and finally reaching the southern mountainous area where Poland and the Czech Republic meet, a distance of more than 490 kilometers in a straight line.

This meant that the original border was no longer within the defensive line, and even half of Warsaw was abandoned.

The Curzon Line is only a dividing line artificially created by historical circumstances, and from a military point of view, it is not at all suitable for defense, even if it is as fierce and tenacious as the Brest Fortress, in the face of large-scale military operations, it is only a slightly larger stumbling block.

Of course, the Germans could not build a Great Wall on Polish soil in one year, and even if they did, they would not be able to stop the red iron hooves. The lessons of the Maginot Line are just around the corner, but the Frenchman's design does have a lot of bright spots from a certain perspective.

Germany adopted a flexible defense tactic of combining permanent fortification and mobile defense, mainly building a number of semi-permanent fortresses at various important communication nodes on the defensive line.

Each fort is built as a firepower stronghold with strong self-sustaining capabilities, and a series of circular anti-tank support points are set around the core fortress, requiring each support point to not only provide cover for each other, but also obtain heavy fire support from the core fortress.

The mobile and flexible German armored detachments could carry out mobile defense between these firing points, and even wait for the opportunity to launch a counterattack against the loopholes in the enemy's formation and disrupt the enemy's attack deployment.

This set of defensive tactics was formed on the basis of the defensive tactics of anti-tank support points in World War II, and both the Soviet Union and Germany suffered a lot from this tactic on the Eastern Front. Xu Jun believed that in this time and space, no one knew more about the power of this method of warfare than he did.

In order to achieve strategic objectives, it was necessary to cover up the true face of the eastern defense line, and the General Security Service and the Imperial Intelligence Service assumed the responsibility of counterintelligence.

The German movement in central Poland was so great that it was impossible for the intelligence agencies of the Soviet Red Army to be unaware, and the purpose of these armed men who secretly crossed the border was probably to gather intelligence information on these defense projects.

The problem encountered by the German side was that the existing manpower of the General Security Service and the Imperial Intelligence Service was insufficient, and because the eastern defense line had drawn a large number of troops from Poland, it was difficult for both the German border police and the army units to draw more men on the Soviet-German border at this time.

When Himmler learned of this, he felt that this was a good opportunity for the SS to show the Führer what he was capable of, so he offered his hidden trump card, the SS special forces training at the Brandenburg School.

Himmler claimed that the inspiration for the birth of this force all came from a dinner party in the capital of a certain Führer, and the Führer first proposed the concept of special operations to him at the dinner table.

Himmler's interest in special forces became more and more keenly with the establishment of the "Tomahawk Brigade". For a long time, the national leader has been obsessed with historical literary depictions of the ancient elite troops, and the concept of special forces has just poked the itch of the SS national leader, and he feels that the mode of operation proposed by the Führer is simply tailor-made for the SS.

So while the Tomahawk Brigade was still training, he ordered a set of training programs for SS special forces based on the course of the Tomahawk Brigade. In addition to sabotage and infiltration tactics behind enemy lines, he demanded that each soldier master at least two or more specialized skills, and also learn to operate all Soviet weapons, control common means of transportation in the Soviet Union, and even horse-drawn carriages and dog-drawn plows.

Himmler knew very well that this force was about to be thrown into the Eastern Front, and that if it wanted to succeed, it would have to be ahead of everyone else.

The recruitment of the troops was smooth, all of them were young men in their twenties, each of whom met or even exceeded the medical standards of the Wehrmacht, which was the main contradiction between the SS and the Wehrmacht, and both sides were in dire need of high-quality soldiers of the right age.

This special forces unit is recruited by all members of the Nazi Youth League, there is no problem with loyalty, and the members have adapted to collective life and are very obedient to the management of their superiors.

In contrast, the Wehrmacht is less political and more focused on the relationship between the state and the individual, but all people must swear allegiance to the Führer when they join the army, regardless of their political views.

Brandenburg trained three battalions of SS special forces at once, which were designated as the 3rd, 6th, and 9th special operations battalions, and Himmler personally gave each battalion a resounding code name.

The SS National Commander-in-Chief gave the 9th Special Operations Battalion the code name "Werewolf", and the unit was transferred to the small town of Biava in eastern Poland. Podlaska. It was just an ordinary Polish town, with nothing to speak of, that had been almost razed to the ground by the Germans during the Thirty-Nine Years' War, and it took more than a year to rebuild only a small part of it.

But that's not the point, the point is that just thirty kilometres east of the town, on the other side of the Bug River, stands the fortified Brest Fortress.
