Just after Marin and the Hanseatic city of Hamburg had reached an agreement to borrow a ship, Marin and his army were still waiting for the ship sent by Hamburg in the harbor west of the Duchy of Schleswig, while at the same time, Emperor Maximilian I of Switzerland gathered tens of thousands of troops at Marin's suggestion and marched to the Aargau region......

Under normal circumstances, in order to ensure the safety of Austria and Burgundy, the Habsburgs set up a standing army of 16,500 people, all of whom were warlike mercenaries.

However, after the occupation of Graubünden at the suggestion of Marin, the Emperor Maximilian I increased the standing army from 16,500 to more than 20,000 men in order to prevent a Swiss counterattack, reaching a high of 25,000 men.

Therefore, this dispatch of 10,000 people is not an all-out effort for the Habsburgs. However, this is also enough. Because, at this time, there were fewer soldiers in Switzerland itself.

However, this time, the emperor's troops and horses did not attack from the Graubünden region in the southeast of Switzerland, but from the side of the Count of Burgundy, that is, from the northwest of Switzerland.

Because of the complex terrain of the Graubünden region, if you want to send troops from the Graubünden region, you must first lead the army through the most powerful canton of Switzerland, Zurich, and then reach the canton of Aargau in the north.

This time, although the entire Swiss army, almost all went out. However, the canton of Zurich was still partially guarded by troops. Those few men, although only two or three thousand, were not enough to openly confront the emperor's soldiers and horses. However, relying on the complex mountainous terrain and strong fortresses, it was still able to hold back the emperor's army.

Moreover, the army of Maximilian I could not afford to drag it out. Although Marin detained 18,000 Swiss mercenaries, there were more than 10,000 Swiss mercenaries on the French side and the Duchy of Guedes.

Once Maximilian I's army was held back by two or three thousand defenders of Zurich and dragged back to France and the Duchy of Guedes, it was difficult to say whether the outcome would be known.

Therefore, Maximilian I decided to attack from the Count of Burgundy in the northwestern part of Switzerland (later known as France-Comté).

This is because the canton of Aargau is located due north of Switzerland, bordered by the canton of Zurich to the east and the bishopric of Basel to the west. Moreover, the topography of Switzerland is high in the south and low in the north. Although the north side is not plain, the terrain is much more relaxed. The dispatch of troops from the Count of Burgundy also avoided crossing the mountains as much as possible.

Historically, the Council of Basel abolished the bishop in 1501 and opted to join the Swiss Union. However, this happened in 1499 when Maximilian I entered the Swabian War and lost to Switzerland.

And due to Marin's intervention, Maximilian I did not rashly participate in the Swabian War, nor was he defeated. Thus, the Bishopric of Basel still exists, and is still a religious prince of the Holy Roman Empire, not yet part of the Swiss Union.

Thus, the 10,000-strong army of Maximilian I entered the Bishopric of Basel from the Count of Burgundy without any hindrance. Because, the bishop of Basel, too, was somewhat close to the empire and disliked the Swiss.

The citizens of the Basel area, however, are close to the Swiss Union. However, because Switzerland had never defeated the emperor, the citizens of Basel did not have the courage to depose the Bishop of Basel and throw themselves into the arms of Switzerland.

The most important thing is that now Switzerland is empty, and the emperor's army is unstoppable at this time.

In normal times, if Maximilian I had sent only 10,000 troops into Switzerland, he would have been beaten into a dog. However, the timing is too good now, Switzerland has more than 30,000 mercenaries, but most of them are outside, and Switzerland itself is very empty. So, although Maximilian I sent only 10,000 troops, he swaggered through the Basel region and entered the canton of Aargau, where the Habsburgs had their birth......

The Aargau canton had nothing to do about it, because at this time, there were only three or four hundred old, weak, sick and disabled people, and it was no match for the Habsburg army.

In normal times, the canton of Aargau can also ask for help from Zurich, the most powerful big brother of the Swiss alliance in the east, and ask Zurich to send troops to rescue him.

However, Zurich only had two or three thousand second-line troops at this time, which was considered old and weak among Swiss mercenaries. These people, relying on the strong local fortress of Zurich, may be able to withstand the 10,000-strong army of Maximilian I. However, coming to the rescue of Allgäu is definitely an act of seeking death. After all, Austria sent 10,000 troops, or elite German mercenaries.

And the choice of the commander of this 10,000-strong army is also very surprising. Because, the man was very young, his name was Frenzberg......

That's right, this is the same Frenzberg, the brilliant officer that Marin gave to Maximilian I, the "father of the German mercenary" in the original history.

Originally, Maximilian I did not trust Frenzberg very much. After all, Frenzberg was sent by Marin. The organizational relationship is still on Marin's side.

But later, because of the strong combat effectiveness of the Marin army, although Maximilian I did not directly reuse Frenzberg, he gave the important task of training recruits after the expansion to Frenzberg.

As a result, Frenzberg began to train the recruits in earnest according to the Spanish phalanx he had learned from Marin, so that the recruits quickly developed combat effectiveness. When defending the Graubünden area, this well-trained recruit exerted a strong fighting force, relying on the mountainous terrain, repelled several Swiss counterattacks, and also suppressed several rebellions of local forces in the Graubünden area.

Then, in the eyes of Maximilian I, Frenzberg became even more important. Like Marin, Maximilian I officially appointed Frenzberg as the phalanx leader of the new army, mainly in charge of the two phalanxes sent by Marin.

But Frenzberg's talent showed that he was capable of commanding several phalanxes. After all, in terms of commanding talent, Frenzberg's talent surpassed that of Marin's number one general, Schwarz.

It's just that Frenzberg's loyal and patriotic thoughts are too serious, and his heart is actually more inclined to Emperor Maximilian I. In the end, Marin chose to cultivate Schwarz, who was more loyal to him, and kicked Frenzberg to the emperor's side, and brought two phalanx of soldiers and horses, which was also considered an explanation to Maximilian I.

Just some time ago, suddenly came the news that Marin had openly drawn a line with Maximilian I. Maximilian I, who had always valued Frenzberg, felt that the opportunity had come......

What chances? To test Frentzberg's loyalty, of course. Although on the surface, Frenzberg was very loyal to Emperor Maximilian I (and in fact he was), Maximilian I, as an emperor, was not so easy to trust.

Therefore, Maximilian I deliberately did not tell Frenzberg the real reason, but deliberately said that Marin was really going to distance himself (he did not know that Marin really thought so). Then His Majesty the Emperor gave Wrenzberg a choice - to return to East Friesland or to stay......

If Frenzberg chooses to return to East Friesland, then, there is nothing to say, and for his departure, Maximilian I, although it is a pity, is not impossible to give up. After all, an unfaithful subordinate, gone and left.

And if Frenzberg chooses to stay, it shows that Frenzberg is a talent worthy of promotion and training by Maximilian I. Later, Maximilian I could safely reuse the ......

After all, Frederick II, Count of Hohenzollern, Swabian, the number one general under Maximilian I, was not too young, and his military talent was average, not as good as that of Frenzberg.

Frenzberg didn't know that this was a test given to him by Maximilian I, and thought that Marin had really parted ways with Maximilian I.

After a night of painful thinking, the next day Frenzberg, with dark circles under his eyes, told Emperor Maximilian I that he was willing to stay. In addition, Frentzberg also wrote a letter of apology, hoping that the emperor would send someone to help send it to Marin......

Maximilian I was overjoyed, and convinced that Marin had not sent anyone to contact Frenzberg recently, His Majesty the Kaiser made the decision to reuse Frenzberg.

So, in the surprise and shock of everyone, Maximilian I appointed Frenzberg as the acting commander of the army, commanding 10,000 soldiers and horses, from the direction of the Count of Burgundy, to launch an attack on the state of Aargau, in order to recapture the ancestral land of the Habsburgs and the land of Longxing, and fulfill the long-cherished wish of the Habsburgs for generations......
