William did not ask King Henry I of France for help this expedition, you must know that it is easy to ask God to send God, and ask King Henry I for reinforcements, then William's power in Normandy will inevitably be restricted, and William does not want to owe Henry I a favor.

In William's ambition, the pacification of Normandy was only the beginning, the conquest of Britain was the starting point of hegemony, and the throne of France was what William wanted most.

The current situation in Europe is that France and the Holy Roman Empire are juxtaposed, but as long as the Holy Roman Empire does not change the law of electoral succession and the electoral system, then the potential of the Kingdom of France, which enforces the law of primogeniture, will far exceed that of the Holy Roman Empire.

With its vast plains and cultivated land, France is located in the middle of the European continent and has a thriving population, which undoubtedly has the foundation for European domination, which is the main reason why the monarchs of England since William the Conqueror have never forgotten the French throne.

William sent 19,000 troops, including 7,800 well-trained Praetorian Guards, which were enough to rival the aristocratic armies that were three times as numerous, and the rest of the army, including the standing militia and the Knights, was far superior to the ordinary aristocratic armies.

This is the source of William's confidence, and William, who is sitting on this tiger army, is confident that he can sweep through the rebels and sweep through Normandy.

......

At the same time, the Earl of Kay, who had received a letter of declaration of war from William's emissary, was furious and immediately gathered a group of rebellious nobles from the factional camp, including Nigel, Baron of Cotentin, Lanouf, Baron of Besan, Hammer, Baron of Affranche, Baron Lanou Tyson, Baron of Tierry, and Baron Gremel of Plessis—and others - to gather an army of about 25,000 men.

The army was divided into two groups, one of which moved south from the Earldom of Mortan in the northwest, aiming at William's army in order to defeat and capture William in World War I, while the other army was a detachment of more than 5,000 men led by Baron Tierry Lanouf Taison, who came from the southwest and was responsible for attacking William's army from behind, attacking the enemy's transport and supply lines, so that William could not take care of each other.

As the main character, William, he leads his army from the parish of Lischel in the county of Evreux to the west, aiming directly at the 20,000 rebels led by Kay, in order to defeat them in battle.

The three armies formed a "Y" shape on the map, and William was very much looking forward to which rebel army would encounter first.

After only a few days of marching, William and Tyson's army met first, and the lightly armed Tyson marched very fast, and he was surprised that William's army had encountered so quickly because he had miscalculated the speed of William's march.

William knew Baron Tyson, and Baron Tyson also knelt on the ground to swear allegiance to William at the allegiance ceremony presided over by Robert two years ago, but he didn't expect that in less than two years, Baron Tyson, who should have followed William, is now on the opposite side of William.

Due to the tacit understanding reached by William through Emma and Sir Tyson, William only brought a few personal guards cavalry to go forward alone, and came to Baron Tyson, who also rode forward alone, and said, "Baron Tyson! You once swore allegiance to me and obeyed my orders, why are you fighting with me on the battlefield today? ”

"I did swear allegiance to you, but yesterday I swore to Kay that I would strike you with a sword." Baron Tyson said helplessly.

"You have two vows, which one are you going to keep now?" William asked rhetorically.

"This—" Baron Tyson was a little embarrassed, he felt that no matter what he did, he would break one of the oaths, and that harming William was something Baron Tyson could not do under any circumstances.

"Then you keep both vows so that you don't break either!" William said.

Baron Tyson looked at William suspiciously, not knowing how to speak.

"Come, Baron Tyson, and strike me with your sword." William urged.

Baron Tyson instantly understood what he meant from William's words, and saw him rush to William's side, he drew his sword, slapped William's shoulder lightly twice, and said to William: "Your Highness William, in this way I have fulfilled my oath to Kay, and now I am your vassal, please allow me to fight for you!" ”

"I look forward to your performance, Baron Tyson, and there will be a place for you in my ducal palace." William replied with a smile.

Receiving William's affirmative reply, Baron Tyson turned his horse's head and shouted to his army: "From now on, I am the Duke's man, fighting for His Royal Highness William, Duke of Normandy!" ”

"Oh! ... Oh! ... Oh! ...”

The continuous cheers resounded in the sky, and the five thousand troops led by Baron Tyson all raised their weapons and cheered, they were dissatisfied with the brutal rule of Kay for a long time, and had long hoped that William could rule Normandy again.

When the cheers subsided a little, William commanded Baron Tyson, who was waiting in front of him to obey his orders: "Baron Tyson, please lead your troops to attack the rebels from behind Kay, disrupt their line, and create fighters for our army to break through the rebel formation." ”

"As you command, Lord Duke." Baron Tyson said respectfully stroking his chest.

After sending off Baron Tyson and his army, when William led his army through Caen, an important county in the county of Mortan, many local nobles spontaneously joined William's camp and obeyed William's orders.

These temporary nobles numbered 2,000 men, and although their combat strength was suspicious, William could not refuse their allegiance, so he had to place them in the knights of Baron Richard, believing that Baron Richard would be able to subdue them.

The next day, William's army of more than 20,000 and Kay's rebels of more than 20,000 met in the plains of the Vals Dunes, and the two sides were evenly matched in terms of numbers, but if the combat strength was calculated, William's army far outnumbered the rebels led by Kay.

The Waars Dunes Plains, located in the eastern part of the county of Mortan, near the present-day town of Conteville, where William's mother, Arlett, and her husband, Knight Conteville, were located.

William and Kay did not send people to shout to each other or anything, but directly sent the vanguard of the cavalry, mainly cavalry, to do it, since both sides are enemies of life and death, there is nothing superfluous to say for so long.
