On the sea, among the flagships of the North Sea Fleet, Gerbo, who was the admiral of the fleet. Fan. The Count of Ostel Zele was anxiously stamping his steps back and forth, as if waiting for something.

Suddenly, an officer came to Count Gerbo, gave him a military salute, and immediately reported: "Lord Admiral, the Greek fire has been thrown on the sea, and all preparations have been made. ”

"Captain Philip, the wind hasn't changed." Count Gerbo reconfirmed.

"Everything is normal, the wind is northwesterly, still the same as previously predicted." Captain Philip nodded in response.

"Alright, order all warships to shoot fire bolts at the sea, and I'm going to bury the Viking longships at the bottom of the sea. And Captain Philip, you have to be ready to attack at any time, your Spitfire fleet is the irreplaceable protagonist tonight! Count Gerbo tapped Captain Philip on the shoulder and ordered.

"Yes!" The crowd responded, and then the order of Count Gerbo was conveyed to the entire fleet.

......

At this time, after the surprise attack of the Normans, the Norwegians and Danes had already reacted, and then King Harald IV of Norway, who had personally rushed to command the battle, immediately organized a fleet and began to counterattack.

Although they lost no less than 200 Viking longships under the Norman attack, many more were still in good condition, and in just a few moments, more than 800 Viking longships were assembled on the orders of Harald IV.

"Assault the whole army, and tear all the vile and shameless Normans apart with me." King Harald IV of Norway commanded loudly, and the words contained endless anger that could be heard by both the Vikings and the Normans.

More than 800 Viking longships sailed out of Calais and the Norman fleet set anchor, adding Viking ships to the fleet, and soon the Viking fleet swelled to the thousands.

However, the sheer size of the fleet inevitably led to confusion in command and affected the speed of the fleet, but Harald IV did not care about this, as long as he left the shallow sea of the port area, the vast expanse of the sea was not the world for their Vikings to gallop, and these crappy Normans were no match for them at all.

Suddenly, news came from the outpost of the Viking warship in front of them, saying that the Normans had dispatched small boats to move in the sea not far away, and they were throwing something into the sea.

Unmoved, Harald IV thought it was the so-called "holy water" of the Christian army, but he suddenly found that the wind was northwesterly, and the sea breeze was pouring into the bow of the Arab fleet with sea water and Greek fire.

"There's grease in the sea! Retreat! It dawned on Harald IV that the boat that had appeared earlier had splashed not Christian "holy water" on the sea, but flammable grease.

But it was too late at this time, the Norman fleet a hundred meters away fired thousands of arrows, the Norman soldiers fired fire arrows into the sea, longbows, crossbow arrows with flames fell into the sea full of oil, the rockets ignited the oil on the sea, and ignited the wooden hull of the Viking fleet, and the vanguard fleet was all burned to the sea.

"Retreat, retreat!"

King Harald IV of Norway continued to shout orders to retreat, only to find a large number of dhows coming out of the Norman fleet, and these small galleons continued to spew terrifying bright "fire dragons" into the chaotic Viking fleet, which shocked Harald IV and all the Vikings at such a distance and with great power.

The flames seemed to have been manipulated by the Normans, and Viking longships were constantly ignited by the flames on the sea, and several sloops signaled "fire dragons" from the Viking fleet, and everywhere the Greek fire passed, all the Viking longships were set on fire, and no one was spared.

The smoke and poisonous gases from the burning of the Greek fires killed a large number of Viking sailors, and the explosions and smoke caused the Viking fleet to collide and sink.

The bright fire dragons and the grease poured on the sea by the Normans are the famous "Greek fire", which was the secret weapon used by the Byzantine Empire to defeat the Arabs several times, and it is the basis of the empire's thousand-year national fortune.

But to be honest, the composition of Greek fire is not complicated, it is mainly composed of oil and flammable substances, and William only pointed out a direction, ordered the secret manufacture of this substance in the royal palace, and successfully cracked the formula of Greek fire. Later, the craftsmen invented a weapon capable of spraying the substance by filling a large number of Greek fires into wooden barrels, using the principle of siphoning to ignite the Greek fire and eject it out of a tube made of bronze.

The Kingdom of England was rich in oil, with several oil fields of various sizes in the southern part of England alone, and larger and more easily exploitable fields in William's newly conquered part of Scotland, which made it possible for the Normans to make Greek fire in large quantities.

It can be said that this naval battle was the first time that the Normans used Greek fire, and even William had no experience in using Greek fire, so the tactics of using Greek fire in this battle were also formulated by Count Gerbo based on the Byzantine literature on the use of Greek fire.

However, even William, who invented Greek fire, did not expect it to be so powerful, and he regarded it more as one of the means to disrupt the formation of enemy warships and siege cities.

The first to come to his senses was Count Gerbo, who recovered from the shock and ordered the entire army to be led by the Spitfire fleet, with the Five Ports Alliance following up to destroy the surviving Viking swords, while the main ships of the North Sea Fleet were responsible for suppressing fire and using them as reserves.

The Norman fleet suppressed the Viking fleet with its inferior fleet numbers, and they did not dare to fight the Normans at all, for fear of being burned to death by the unquenchable flames ejected by the fire dragon.

The Viking fleet was forced back to the port of Calais by Count Gerbo's fleet, and most of the Viking longships were either burned by Greek fire or sunk during the retreat, while the remaining Viking longships were temporarily incapacitated due to the Vikings' lack of will to fight.

King Harald IV of Norway saw that he could not do anything, so he had to take people back to the shore, and as for the ships in the harbor, he could only give up painfully, and even the ambitious monarch lost the courage to face the inexplicable Greek fire.

However, just as Harald IV was about to lead his army back to the camp, a raging fire rose from the Norwegian camp behind him, and screams continued to be heard.

"That's our camp, our camp has been attacked by the Normans!" Harald IV was speechless in shock, and stood stunned and bewildered.

However, after all, Harald IV quickly reacted from the shock and decisively ordered the whole army to return to the camp to rescue the camp, at least to reduce the losses to a minimum.
