Marin is on the emperor's side, so he naturally has his own eyeliner. In the two phalanxes led by Frenzberg in Graubünden, there were many intelligence officers.

The process of Vrenzberg's final choice to serve the emperor after a complex ideological struggle was naturally noticed by the intelligence officers, and quietly passed through the post station system, through the relay of horses, and was soon delivered to Marin.

For such a piece of information, Marin's heart was very painful. In any case, Frentzberg was the first historical celebrity to be recruited by Marin, before Leonardo da Vinci and Machiavelli. Moreover, in the early days, Marin even thought about letting him replace Schwartz as the second only to Marin himself in charge of the army.

However, Marin then discovered that Frenzberg seemed to have a great affection for the Habsburgs. The Swabian League, where his father served, was also a supporter of Maximilian I.

Marin had also been tempted, and it just so happened that Maximilian I wanted Marin to send troops to support his operations in the south. Therefore, Marin simply asked Frenzberg if he would like to lead his troops south to support His Majesty the Emperor. Unexpectedly, Frentzberg was very positive. In desperation, Marin had no choice but to let him lead two phalanxes south to serve the emperor. And the position of the second person in the army, Marin was eventually given to the more loyal Schwartz.

Of course, Frenzberg went south with two phalanxes to serve the emperor. However, its "organizational relations" are still in the East Friesian Lamberland. Nominally, Frenzberg was in the service of His Majesty the Kaiser instead of Marin.

Marin, on the other hand, also pinned some hopes on Flensberg that he would eventually return. After all, no one dislikes the talent under them. Look at those who have crossed the Three Kingdoms, which one of them was not packed up and taken away by the ministers?

However, this time, taking advantage of Marin's public announcement of a break with the emperor, Maximilian I cunningly made Frenzberg choose sides. As a result, Frenzberg finally chose Maximilian I, much to Marin's heartbreak.

In fact, in Marin's heart, Maximilian I had long since lost his head, and who made him unashamed to speak out when he was young about unifying all of Germany? From then on, Maximilian I became the tacit enemy of the princes. From then on, no matter how talented Maximilian I was, it was difficult to show it. If Maximilian I wanted to expand, he had to ask the princes if they agreed.

Marin is different, before, he followed Maximilian I as a horse boy, and he was naturally subject to various constraints in diplomacy. But this time, after being forced to declare a clear line with the emperor, he untied the shackles in his heart, and since then the sky has been free for birds to fly.

……

But Frentzberg couldn't see that. Frenzberg, although talented, was also only military. Politically, Frenzberg is still a little worse.

Moreover, the loyalty and patriotism of the traditional knight were also very important in Frenzberg's heart. After all, Frentzberg was born into a family of knights. Therefore, in Frentzberg's heart, he was more inclined to the side of the emperor with a righteous name.

Moreover, Maximilian I is also very capable and has more means, and will win people over. If he hadn't died at a young age and expressed his desire to unify Germany, he wouldn't have done so now. It can be said that Maximilian I spent the rest of his life paying for the arrogant words of his youth.

However, Maximilian I's means and charisma were very strong, which deeply attracted Frenzberg, who had been with the emperor for a long time. So, after a fierce ideological struggle, Frenzberg abandoned Marin, who had cultivated him, and chose to serve His Majesty the Emperor. In Frenzberg's heart, he was actually very much in favor of the French centralized system. He believed that since Marin was also a courtier of His Majesty the Emperor, it was reasonable for him to serve His Majesty the Emperor as a courtier.

……

Marin was very unhappy about Frentzberg's betrayal, but he did nothing. After all, Frenzberg followed him very early and knew a lot of secrets. In particular, the secret of increasing grain production. Although Frentsberg didn't know much about the details, he certainly knew that manure was an important fertilizer. It would have been miserable if Frenzberg had revealed this secret to the emperor.

Therefore, despite the upset, Marin wrote to reassure Frenzberg and expressed his support for his decision. Moreover, Marin emphasized that he was also forced by the princes to publicly declare that he had drawn a line with the emperor. And Frentsberg's service to His Majesty the Emperor is equivalent to serving His Majesty the Emperor. After all, it was Marin who brought out the Frenzberg. The two most elite phalanxes of the 10,000-strong army under his command were also sent by Marin......

In addition, Marin also said in his heart that Frenzberg's baronial title in East Friesland would continue to be retained as well as the manor fief. However, at the end of the letter, Marin hoped that Frenzberg would keep the fertilizer secret......

Frenzberg is still a man of a little conscience, after all, a loyal and patriotic person is not much worse. For turning his back on Marin to choose the emperor, Frenzberg already felt very guilty, Marin asked him to keep the secret of fertilizer, and Frenzberg naturally agreed and swore an oath.

Marin is naturally very satisfied with this. Moreover, Marin also planned to take good care of the estate that Frentzberg left in East Friesland in the future, so that Frentzberg could remember his goodness.

Seeing that Frenzberg will become a celebrity in front of the emperor in the future, it is always right to have a good relationship with him. Although Marin is now reluctant to be the emperor's horse, the power of the emperor's faction is not weak. Maybe one day, Marin will need to use their power to achieve his own goals. Therefore, there is nothing wrong with having a good relationship with Maximilian I.

Shortly after Marin received the letter from the Wrenzberg side, the fleet from the Hamburg side rushed to the station of Marin's army, Tenning at the mouth of the Aide River.

In fact, at this time, Tengning had not yet established a town and a port, and was still just a small fishing village. However, Marin is very optimistic about this small fishing village. Because, Tenning is located at the western end of a "great river" in the south of the Duchy of Schleswig. Moreover, to the southwest, Tengning is a trumpet-shaped outlet harbor, but there is a certain contraction in the place where it is connected to the sea. In this way, this side makes for a very good haven.

Although, the water depth here is not enough, and it will not be able to dock a 10,000-ton freighter until the next generation. However, this era is different. In this era, because the tonnage of ships was generally small, few exceeded 500 tons. Then, the harbor of a large river estuary like Tengning has become very good. Moreover, because it is the mouth of the Tamsui River, the boats are docked here, and they are not afraid of boat maggots gnawing the bottom of the boat. As a result, it is ideal as a port at the southwestern end of the Duchy of Schleswig, and it is a safe haven.

Therefore, the Marin faction built a large number of long-bridge wharves in the small fishing village of Tengning, and planned to build small towns on the spot after the war, and develop them into commercial ports, which became an important wharf for the Duchy of Schleswig to connect with East Friesland proper. Moreover, Marin also plans to build a military port here and dock some warships to ensure the safety of shipping in the North Sea.

Because a large number of long bridge wharves had been built in advance, when the ships from Hamburg arrived, Marin immediately organized the soldiers to carry all the food, baggage, artillery and ammunition on the ships. Then, everyone also lined up to board the boat, including Marin.

Hamburg is only 250 kilometers away from Wittenberg, and within a few days, a mighty fleet of ships has crossed the wide Elbe River to the city of Wittenberg.

Upon the arrival of the fleet, Marin immediately arranged for some of the elite to land and take control of all the shipping docks in Wittenberg to prevent sabotage by the Saxons. Then they sent the cavalry ashore first, and let them patrol the vicinity of Wittenberg to prevent John and his children from escaping.

In the end, Marin led most of his subordinates to use the shipping dock of Wittenberg unhurriedly, landed in batches, surrounded Wittenberg, and set up a large camp......
