At this moment on the battlefield, Sancho, the once high-spirited King of Castile, looked at this scene in front of him with distraction, the knights of Castile who once roamed the Iberian Peninsula were now trembling under the scarlet spears of the Norman knights, and the armorers with zither-shaped shields were once the backbone of his reliance, and the shield wall they formed was impregnable, but now they fell one after another in front of the shells fired by the cannons and the lead bullets ejected from the muskets.

No matter how brave the knights and hoplites were, how vulnerable they were to the glittering cannons and muskets, and they were senselessly killed by the projectiles fired by the Normans before they even approached the position of the Norman phalanx.

What brave knights, their names can still be clearly remembered by Sancho, the loyal and brave Sir Ordono, the energetic young Baron Ferdinand. Morality. How did Giron and his younger brother the Knight of Tello, the proud Sir Antonino, the loyal and brave Holy Knight Diego the Elder, die on the battlefield one after another, and this did not make Sancho grief-stricken.

A year earlier, when Sancho had just taken the throne, he was determined to follow in the footsteps of his father, Ferdinand the Great, and to become a great monarch. His greatest dream in life was to unify the surrounding kingdoms and form a great power.

By swearing to Sancho, King of Aragon, to become brothers, and swearing that if anyone died first and had no heirs, another would inherit the country, and Sancho gained a loyal ally and a marriage.

Soon he married Uraka, a princess of the Kingdom of Aragon.

Sancho's younger brother Alfonso inherited the kingdom of León, and shortly after Sancho's marriage, he also held his own wedding, perhaps in order to make peace with neighboring Castel, and he invited Sancho and the king of Aragon to witness his wedding.

However, at the wedding feast, his sworn brother, Sancho, king of Aragon, disappeared but disappeared, and after a while, the palace guards ran up to him and told Sancho that the king of Aragon had died in the palace toilet and had been killed with a knife.

Sancho was suspicious at the time, he was convinced that his sworn brother, the King of Aragon, had been killed by his own brother Alfonso, and that his sworn brother had unfortunately been killed by Alfonso's plot in his place.

Returning to Castil, Sancho inherited the throne of the Kingdom of Aragon by swearing to each other, and then he led a mighty army of the two countries to besiege the capital of León.

Sancho wept in front of the crowd and swore an oath to avenge his brother, the King of Aragon, and loudly scolded King Alfonso for his assassination of the hero of Castile.

At that time, the army of Castile was impressed, and the knights obeyed the command of Josan and captured the kingdom of León.

The noble Alfonso was a master of intrigues, but his military prowess was no match for Sancho's, and his army was routed by the enraged Castillean army.

With Alfonso fleeing to Salamanca in the south, Sancho seized the opportunity to capture León and proclaimed himself king of the three kingdoms of León, Castile, and Aragon.

Sancho was in high spirits at the time, his brother Alfonso was a lost dog, and Garcia cowered in the castle of Santiago, waiting for his final fate.

However, at this time, the ambitious William, his brother-in-law, who seemed to see himself unifying Castile and becoming a great king, fabricated the facts and blatantly invaded Castile in disregard of the alliance between the two countries.

Sancho was hesitant at the time, after all, he had grown up listening to Willian's deeds since he was a child, and he knew very well what kind of opponent he was about to face.

In the face of such an opponent, even if his father Ferdinand I was alive, he might hesitate.

However, the situation was extremely critical at that time, the fortress of San Sebastian in the Pyrenees continued to hear of the Norman army, and within the kingdom there was his brother Alfonso still entrenched in the south of the kingdom, and in the west of the kingdom was the self-defended brother Garcia, and the untamed princes of León, and he could only use the only army he had at his disposal of less than 20,000 troops.

Even so, Sancho mustered up the courage to lead 20,000 horses to the fortress of San Sebastian in the Pyrenees to join forces with Sancho IV, King of Navarre, to fight against the mighty Normans.

At the same time, in order to unite all the forces that could be united, Sancho mercifully pardoned his brother Alfonso and returned the country of Leon to him in exchange for Alfonso's joint fight against William's invasion.

It's just that in the end, Sancho had to admit that he had lost his eyes, and the viper was still a venomous snake no matter what, even if it was fangs extracted, even if it was pressed with a pair of teeth without venom glands, it would still betray itself at its most critical moment.

Almost, just little, the Castile knights on the right flank bravely entangled the Norman knights, while the Castillic heavy cavalry on the left flank almost broke one of the opposing wings in the rain of cannons and muskets.

Had Alfonso had attacked the Normans' flanks as he had agreed with them, the victory in the war would have been for him and Castile.

However, just as time does not turn back, there are no ifs, and the Castille Knights' achievements on the enemy's left flank did not translate into an advantage, and they were soon routed by the 1st Norman Guards Cavalry Brigade.

With the defeat of the Knights of Castile, the war also slipped inexorably in the direction of defeat, the cavalry on both flanks was defeated one after another, and the heavily armored men, deprived of cavalry support, could not get close to the large phalanx of the Normans under the rain of artillery and muskets.

At the same time, his ally, King Sancho IV of Navarre, after hearing that his kingdom of Pamplona had been attacked by the Normans, abandoned his allies and fled with his Navarre legions.

At that time, the Navarre army was placed on its right flank, near the Pydasoa River, and the flight of King Sancho IV of Navarre directly led to the vacancy of his right flank defense, so that the right flank of Castille was replaced by Robert Castile, who led the troops later. Morality. Conteville was quickly routed.

His right flank was routed, his left flank was surrounded by Norman cavalry, and the center was full of approaching Norman phalanx oppressors, while his rear was the city of Pamplona, the capital of Navarre, which was occupied by the Normans, and it could be said that Sancho had no way out.

"King Sancho, as long as you are willing to surrender, my lord is willing to guarantee your crown and canonize you as Count of Castile." At the last minute, Sancho, surrounded by Normans, received a letter of surrender from William.
