William defeated the Duke of Leofric of Mercia and drove him to Lancaster, north of Mercia, where his next target was Ward, Duke of Northumbria, Yorkshire. Northumbria.

Sword. Although Northumbria is the only two powerful factions in the alliance of the northern princes, he has obeyed Duke Leofrick on many occasions, attached to him, and respected him as the leader of the alliance of the northern princes. After the historical information of the Duke of Northumbria, it was discovered that he was not as cowardly as he appeared, but a strongman duke.

Sword. Born in Scandina, Northumbria was a Viking in the Kingdom of Norway who served Cnut the Great when he invaded England and seized the throne in 1016.

After arriving in England from Scandina, like Sword, they settled in Yorkshire and Northumbria, and became the base of Canute the Great's rule over England.

But as the center of gravity of Canute the Great shifted south, he no longer had the energy to rule the Vikings of Northumbria himself.

In 1033, Sword was appointed governor of York and head of the Vikings living in York and Northumbria by Canute the Great, and controlled the southern part of Northumbria, which is now Yorkshire, and administered the Northumbria region on behalf of Cnut the Great's lieutenants.

In 1040, in order to consolidate his rule, Sword. Northumbria married Elfred, daughter of Edred, Earl of Bamburgh, who had entrenched roots in Northumbria, and widow of King Duncan of Scotland.

Through his marriage to the Bamburgh family, Sword. Northumbria consolidated its position in the Duchy of Northumbria.

However, in 1041, after Sword's position had been secured, he was driven by ambition to kill Edred's younger brother and successor, his own uncle, Edoff. Bamburgh, and seized the Duchy of Northumbria as the son-in-law of the Bamburgh family.

Sword used all his power to support Canute the Great's successors, Hardknout and Edward, in exchange for two kings recognizing him as Duke of Northumbria and extending his power to the south, controlling Northampton and Huntington.

Without William's presence, by 1050 Sword would have sought control of the Earldom of Cumberland and opposed Macbeth, the ruler of Scotland, perhaps without his ambition to seize the Scottish throne as the husband of Elfred, the widow of the former king Duncan.

In 1054, Sword. Northumbria's eldest son, Osborne, died in the war between Sward and King Macbeth of Scotland.

It is recorded in the book Macbeth: "At this time Earl Sword entered Scotland with a great army, including the fleet and the ground forces. Fight the Scots, kill King Macbeth of Scotland, take all the best lands, and keep them as your own spoils. During the war, his son Osborne was killed, and his sister's son Sword, along with his bodyguard, and the king's bodyguard, were asleep on the day (July 27). ”

The battle was fought in northern Scotland, Fosted, and was known as the "Battle of the Seven of Sleep" or "Battle of Dunsnern".

Combining the historical materials in his hands and William's knowledge of this history, an ambitious and cunning prince came to his mind.

In the face of such an opponent, William did not take it lightly, he gathered all his troops, abandoned the castles and towns of Warwickshire, Leicestershire and Derbyshire, and prepared to concentrate all his efforts against Sword. Duke of Northumbria.

From Leicester, William made his way along the River Trent, which originates in Derbyshire, flows through Leicestershire, Lincolnshire, and joins the River Uss in Yorkshire into the North Sea.

Naturally, before the opening of the voyage, William also had to send warships to clear the waterway, and with the naval power in his hands, he only sent a large number of dragon-headed warships to defeat the Northumbria fleet and control the waterway in a short time.

Along the river, William was unhindered and approached the city of York.

Slightly different from Duke Leofrick's strategy, Sword. The Duke of Northumbria did not leave his capital, York, and tried to delay his time by relying on the city's strong defenses to defend against the Normans who invaded Yorkshire.

Judging from the current situation, time is not on William's side, if William can't conquer York City in a short time, he will have to face the landing Viking reinforcements.

Even if he was as strong as the Norman army, William had to retreat with a grudge against the long-conquered city of York and the Vikings who landed on the Yorkshire coast.

However, perhaps because William led his army too quickly, Sword. Northumbria may not have heard of William's one-day assault on Coventry, nor did they know William's impressive record in Warwickshire, Leicestershire, and Derby, and no castle or city could withstand the twin onslaughts of gunpowder and counterweight trebuchets.

Looking at the magnificent walls of York in front of him, the magnificent buildings left over from the Roman era, William may be able to understand that Sword. The reason why Northumbria was so confident that it could withstand the Norman attack was indeed as magnificent as the walls of York could not be easily conquered by ordinary medieval armies.

The walls of York are the most intact and longest preserved of the ancient walls of all of England. The city walls were first built during the reign of Emperor Constantine the Great in ancient Rome, and outside York Minster, there is also a statue of Constantine the Great to record the history of that era.

Later, the walls of York were re-fortified by the Vikings from Denmark, who changed the original pirate lifestyle here, settled down, and developed York into a trading town, named York, which still has many Viking Age buildings and the York Museum, which records the history of the Vikings.

Most of the remaining York Walls were rebuilt between the 12th and 14th centuries. Attentive people will find many copper needles on the walls of the city, which were planted by local archaeologists and engineers to accurately determine the location of the restoration.

The walls of York are a 5-kilometer-long square wall built by the Romans, with a total of four gates leading to the center of the ancient city, which surrounds the ancient city of York and acts as a barrier against foreign enemies.

The city walls are centered around York Minster, and it takes about 2 hours to circle the city walls.

Looking at the imposing York City Wall, William was familiar with its history and glorious past, although he could not bear to destroy the York City Wall, a monument preserved from Roman times, but for the victory of the war, William could only ruthlessly order the whole army to attack the city.
