The Norman kingdom and the great kingdom of Europe, and his and his possessor William were constantly watched by other nations and princes, including his allies, his rivals and enemies, and those who did not want to do it, but when William ordered an expedition to Mecklenburg and Pomerania, the surrounding countries moved almost simultaneously.

King Swain III of Denmark, the closest to Mecklenburg, sprang into action, and he gathered his army and drove first to Holstein, near the Duchy of Mecklenburg, as if to take advantage of William's expedition to Mecklenburg and Pomerania.

However, the Danish move was somewhat puzzling, and after the army had been assembled and arrived in Holstein, they did not immediately declare war on the Mecklenburg chieftain Conyito, but in the name of convincing their homeland, they went to war against Lübeck, which was part of the Holstein territory.

Lübeck was at this time an independent state that struggled to balance the power of Denmark, the Holy Roman Empire, and the chieftains of Mecklenburg in order to survive in the gap between the three, but with William's expedition to Mecklenburg, this balance of power changed dramatically, giving the Kingdom of Denmark the opportunity to take advantage of the law of war in Lübeck.

The Danes were not drunk, no matter who knew this, and their purpose was very clear, that is, they wanted to take advantage of the bitter battle between William and the chief of Mecklenburg, and take advantage of the opportunity to raid from behind, so as to seize territory and benefits.

In addition to the Danes, in Mecklenburg and southern Pomerania, the Dukes of Saxony and Brandenburg also took action.

Bernhard II, Duke of Saxony, was always ambitious, and he also had an eye on the rich and weak Lübeck, and when he saw that the Danes had begun to use troops against Lübeck, he immediately mobilized the knights and troops in his domain, and set sail for Lübeck.

The army was commanded by Odof, the eldest son of Bernhard II. Although this man is not strong in military ability, he should be assisted by a noble general who can fight well, and there are always many people, enough to compete with the Danes for Lübeck.

As to whether or not they had ambitions for the territories ruled by the Mecklenburg chieftain Coneto, it is obvious to anyone with a discerning eye that the Saxons have always regarded the territories east of the Elbe as their own territory, and have been their main direction of expansion.

Historically, the Duchy of Saxony has been expanding its territory east and north of the Elbe for almost a century, and Hamburg is the result of these years.

If the Duchy of Saxony opened up the territory north of the Elbe, the greatest credit is Henry the "Lion" of the Welf family hundreds of years later, the Duke of Saxony and Bavaria.

In 1156, Henry the Lion, Duke of Saxony and German commander, crossed the Elbe River to occupy the areas inhabited by many Slavic tribes, which seemed shocking at the time, but laid the foundation of what would become the territory of the German Empire, and a large part of the territory of Germany is now won by Henry the Lion.

In 1159 AD, Henry the "Lion" established many famous commercial cities in the occupied area, the most famous of which was Lübeck, one of the two giants of the Hanseatic League, and he also established the coastal city of Munich, in addition to the important commercial cities such as Munich and Braunschweig, it can be said that "Lion" Henry was not only a great conqueror, but also an outstanding ruler.

Henry the Lion's achievements were very high, as the commander of Germany and the most powerful prince of Germany, his greatest achievement was to cross the Elbe River and occupy the areas inhabited by many Slavic tribes, this kind of action is some act of aggression from the point of view of the Slavs, but if you look at it from the point of view of the Germans themselves, it is a heroic act of expanding the territory.

In addition to the powerful Duke of Saxony, another German prince, Salo-Judu of the Udonen family of Duke Brandenburg, also began to gather troops.

However, it seems that the Duke of Brandenburg's target was not his northern Mecklenburg, because he knew very well how extraordinary the military talent of the Mecklenburg chieftain Kang Yituo was, which could be called a strategic genius, and the military strength of the Mecklenburg tribe was also extremely strong, and the number of troops he could mobilize could reach 30,000, and the number of excited troops was more than 10,000.

Therefore, the Duke of Brandenburg declared war on the weaker Pomeranian tribe, whose chieftain was dying and could only survive by helping the Mecklenburg tribe, and now that the other party is unable to protect itself, how can he still save Pomerania?

In addition to the three vultures of Denmark, Saxony and Brandenburg, there is a strong male lion lurking near Pomerania, and that is the mighty Kingdom of Poland.

Twenty years ago, Pomerania and Mecklenburg were the fiefdoms of the Polish dukes, but they were lost from the hands of the Poles after the polytheistic revolt eighteen years ago, so the Poles could claim to have regained their homeland.

Ambitious to regain his homeland, the Polish king Casimir the Rebuilder sent his eldest heir, Duke Bolesław of Great Poland, known as the "Fearless", to lead 20,000 troops and swear to conquer the country.

The Poles, the most powerful of these forces vying for Mecklenburg and Pomerania, did not need to hide their intentions, but brazenly raised the banner of the capital's homeland, and continued to gather troops along the way towards Danzig.

As the initiator of this war, the Norman expeditionary force had entered the Danish waters from the North Sea, passing through the island of Zealand, and was about to arrive at the destination of this expeditionary force, Rügen.

The composition of the armies involved in this expedition was somewhat more complex than that of several other armies led by William himself, and less than 6,000 of them were standing armies from their respective legions. Feng. Hohenzollern said to lead, and the rest were mostly Norman nobles who responded to William's call and spontaneously formed troops, including knights, servants, soldiers, levies, mercenaries, Norman adventurers, etc.

Among them, the two brothers, Mephistopheles as the Duke of Leinster and Albert as the Duke of Gwyneth, tried their best to cobble together an army of about 5,000 people and followed the expeditionary force to attack.

Being able to cobble together an army of more than 5,000 men was already the limit of what the two brothers Mephistopheles and Albert could recruit soldiers, after all, the barren Ireland and Wales could only support their troops at most.

Rügen, the Baltic island in northeastern Germany, the largest island in northeastern Germany, was already in sight, and the people dressed in it, whether nobles or soldiers, were all waving weapons and hats and cheering loudly.
