It took a week for William to finally take the castle of Mount Trajoli, and although the loss of thousands of soldiers was heart-wrenching, what he needed to cherish more now was time.

Only by defeating Henry I before he could rally his allies in place would William be able to achieve ultimate victory at a much smaller cost.

At the same time, William also received news of victories in the east and west, in which the Eastern Route Army led by Duke Andrew defeated the army of the Duke of Flanders, and he was leading his army to pursue and capture the castles and towns along the way, while the Western Route Army led by the Duke of Richard won a brilliant victory.

The Duke of Richard defeated the mighty Duke of Champagne and captured him in the battle, the best news he had ever heard, and it meant that there were no more powerful princes near Paris who could stop his march into Paris.

In order to boost the morale of the army, William passed the two good news to the army. Sure enough, after receiving these two good news, the morale of the army quickly rose to the peak, and everyone realized that victory was beckoning to them.

At ten o'clock in the morning of May 26, 1050, William led his army south, and finally encountered the main force led by Henry I himself at Versailles, 15 kilometers southwest of Paris.

Versailles is a satellite city of Paris, France, and the capital of the Yvelines department, which was once the administrative center of the French Bourbon dynasty, located 15 kilometers southwest of Paris, is an art city, and the famous Palace of Versailles is the pearl of French art. The Palace of Versailles is located in the town of Versailles, the capital of the Yvelines department in the southwestern suburbs of Paris, France, and served as the court of France for 107 years.

At this time, however, the town of Versailles did not have magnificent palaces and gardens, it was just a small and inconspicuous town, surrounded by small villages.

The reason why William chose to march into Versailles was to join up with the Duke of Richard, who had arrived from the Countdom of Chartres, and he was ready to capture Paris with a huge force of more than 45,000 people, and completely destroy the confidence of Henry I.

Obviously, Henry I also sensed William's intentions in his unusual behavior, and in order to prevent William from meeting with the Duke of Richard, he personally led an army of 20,000 to fight William to the death.

Compared with the previous wars, Henry I's strength has become much stronger, before he only had two counties, Paris and Orleans, surrounded by princes in the isolated island of Paris, and the King of France was also nicknamed the King of Île-de-France.

But as the struggle between Henry I and William intensified, the Duke of Flanders, the Duke of Champagne, and the Duke of Valois were successively involved in the war.

Because of this, Henry I was able to draw an army of 20,000 to the decisive battle, and even had the spare time to build a castle and place a guard.

However, the 20,000 army in the hands of Henry I was still not enough in front of the Normans, and the nearly 30,000 troops in William's hands were far superior to Henry I's army in terms of numbers and combat effectiveness, and I really don't know what gave him the confidence to defeat William.

However, William could guess a thing or two, the succession of good news these days was indeed bad news for Henry I, he could feel that the three armies of the Normans were forming a siege of Paris, he could not afford to lose Paris, and in order to defend Paris, he had to defeat William before he could join the Western Route Army.

Because it was a decisive battle on the plain, the town of Versailles had no way to rely on it, so the armies of the two sides spread out in turn in the wilderness, and the formation was decent, at most the Norman formation was much wider and deeper than that of the French.

In this battle, William planned to use the Norman longbow phalanx as the core, and use the conventional style of longbow and cavalry to defeat Henry I's army.

This tactic was tested in the Battle of Hastings. Godwinson is under this strategy.

In front of the battle, several horses were still arranged in front of the Norman longbow phalanx and cut wooden stakes were erected to prevent the French cavalry from raiding our longbow phalanx.

Behind the Norman longbow phalanx were dozens of dense phalanxes of Norman heavy infantry, interspersed with crossbowmen armed with crossbows and light infantry in leather armor and swords and shields.

This infantry phalanx was designed to use the heavy infantry phalanx and the pike phalanx as the core, with a dense formation to block the enemy's onslaught, and the phalanx as a city wall, so that the crossbowmen and light infantry could calmly harvest the enemy.

This infantry phalanx was actually adapted by William from the Spanish phalanx, but it is a pity that he did not make a large-caliber arquebus, otherwise its power could have been further enhanced.

However, Willian did not have to be rigid, he did not ask for such a formation in the attacking career, as long as they maintained the formation.

Behind and on the sides of the infantry phalanx were a large number of cavalry, ready to charge at critical moments.

The full-body plate armor of those high-ranking nobles was naturally purchased from Normandy at a high price, but the relatively poor knights did not have the financial resources, and they were still equipped with chain mail and iron helmets that had been passed down from their ancestors in the family.

It is well known that although the chain mail worn by knights is generally double-layered, and the double layer of dense chain mail provides better protection, like the scale armor with many gaps, the chain mail is weak in resistance to stabbing and bowing and arrows.

What's more, the long arrows fired by the longbowmen were as powerful as crossbow arrows, and there were not many polite things to talk about before the First World War, and William and Henry I both regarded each other as mortal enemies, so they did not spare their hands, and each used his strongest killing move.

The sound of horses' hooves was heard in front of the Normans, and it was clear that the first to attack were the French knights that Henry I was proud of, and the French knights, numbering as many as four thousand five hundred, seemed to Henry I to be enough to destroy the Norman formation.

However, to Henry I's surprise, the French knights were hit by a torrential rain of arrows after entering the 200-yard range of the Norman longbowmen, and except for a few high-ranking nobles wearing full-body plate armor, those French knights wearing chain armor and iron helmets were all killed by several arrows.

The general chain armor can't be put down at all. And even if some knights were lucky, the horses under his seat would not be able to survive the dense rain of arrows.

Just ten rounds of continuous arrow rain covered, thousands of French knights who rushed to the sprint fell off their horses, lost their combat effectiveness, and even more were injured.

"It's time to fight back, the knights strike!" William shouted an order, ordering his knights to deliver a heavy final blow to the French knights.
