In fact, the Han Dynasty had a navy, and the main battleship was the building ship.

In the Western Han Dynasty, the building ship has been mass-produced, and in Liu Xi's compilation of "Interpretation of Names and Soldiers", "the first floor of the building ship is called Lu, the second floor is called Feilu, and the third floor is called the Bird Room." Du You's "General Dictionary" "Building a ship, building a three-fold building on the ship, a column of female walls, battle grids, tree flags, open windows and spear holes, and place throwing cars, stones, and iron buckets, like city ramparts." Basically, the structure of this kind of ship is generally divided into three layers, but there are as many as five layers and ten layers, because of the huge hull, more than 10 zhang high, it is one of the main types of ships in naval warfare. During the reign of Emperor Guangwu of the Eastern Han Dynasty, when Gongsun Shu gathered troops to accumulate grain and rebelled against Shu, he once built a 10-story building ship.

A building boat is equipped with a stone thrower, a strong crossbow, and an auxiliary boat, and can accommodate hundreds of people.

The person who is responsible for commanding the fleet is called General Lou Chuan.

There were garrisons in Qingzhou, Xuzhou, and Yangzhou, which were directly under the command of the imperial court. Later, Dong Zhuo rebelled, and these sailors ran out of food, and they became the private property of the princes everywhere.

The last general of Lou Chuan was called Gu Yue, and now he has defected to Yuan Shao and become Yuan Shao's subordinate, this time he was ordered to lead the fleet to attack the rear defense of Jizhou.

Gu Yue has lived in Qingzhou for a long time, and he knows the terrain around the Bohai Sea very well, and knows that Zhang He only has 3,000 cavalry in his hands, so he plans to walk his dog and exhaust this team of men and horses.

"Report! General, the cavalry on the shore stopped! ”

The men in charge of spying on intelligence entered the command ship.

Stopped?

Gu Yue smiled slightly.

Finally can't hold it anymore?

This is also inevitable.

When marching on the water, people travel on the boat with the help of water and wind, even if it is a month or two, they will not get tired, but the march on the road can only borrow manpower and animal power, and this manpower and animal power will eventually be exhausted.

This general on the shore supported him for four or five days, which is commendable.

"General, should we find a suitable place to land?"

No hurry!

Gu Yue waved her hand.

His gaze fell on the map.

The Bohai Sea is very large, and although there are several ferries around, they will also become the object of the other party's attention, and it is difficult to land even if they drive over.

Although they have 50,000 people, most of them are naval forces, and they are not at all the opponents of ordinary infantry in land battles, not to mention that the opponent has 3,000 cavalry.

There were two roads in front of Gu Yue, one was to find a place to land along the coast, so that Hou Hou could gather troops to attack the back of the Jizhou defense line.

The advantage of this is that the army can be mobile and flexible to attack any target at will. The disadvantage is that there is no fleet support, and supply is a serious problem.

The other is to go up the river along the estuary of the Yellow River and sail into the hinterland of Zhangwu County, and advance by waterway, so that they can take care of each other and ensure the supply safety of the landing army, but the disadvantage is that they must advance along the river and the landing force cannot leave the river bank.

As a general of the navy, Gu Yue naturally prefers the second method.

With warships as the foundation and gradual progress, even if the attack fails, there is a way to retreat.

After all, there are no ships in Jizhou, and there is no way to take them.

Thinking of this, Gu Yue hurriedly ordered.

"Pass my order, advance at full speed, enter from the mouth of the Yellow River, advance along the river, attack the surrounding counties along the road, disrupt the rear defense of Jizhou, and cooperate with General Yuan's strategy."

Promise!

Everyone answered in unison!

……

Seeing hundreds of ships marching north, two figures appeared on the shore not far away, it was Zhang He and Zhao Dazhui.

The two of them held a strange cylinder in their hands, and there were two lenses at one end of the cylinder, which could be stretched and stretched, and through this strange cylinder, they could see the situation three or five miles away.

Because of this, they don't have to chase Qingzhou's ships all the time, they just need to stay far behind, saving a lot of physical strength.

"The lord really has the power to penetrate the heavens and the earth, how did he create such a miraculous thing."

Zhang He couldn't put it down, holding this thing and studying it over and over again.

It's called clairvoyance!

Zhao Dazhui said proudly.

It turned out that Guo Jia bought a few pieces of high-purity crystals at a high price, and then hired skilled craftsmen to polish them for dozens of days, supplemented by bronze materials, to make a primitive telescope.

Although it is not as accurate as that of later generations, it is also very advanced in this era.

Clairvoyance?

Zhang He couldn't help but nodded.

Although they may not be able to see the situation thousands of miles away, it is also very surprising to them.

"It is said that this clairvoyant is a treasure dedicated to immortals, and ordinary people are blessed at a glance. When the lord was an immortal in Donghua in his previous life......"

Zhao slitched his saliva and began to blow hard.

This guy has never changed his love of pretending to brag.

Ok ok!

Zhang He shook his head helplessly.

In order to expand the prestige of Yunzhou, Guo Jia deliberately packaged Zhao Dazhui and made him a man of the year in Yunzhou.

Zhao Dazhui also lived up to expectations, and became stronger and stronger in the pretending career, becoming a veritable king of force.

It's just that now Yunzhou's strength is getting stronger and stronger, and there is no need to pretend to be forced to set off himself, so Zhao Dazhui has not come in handy over the years.

It's easy to have an opportunity to show off, how could he miss it.

However, he didn't choose someone to pretend to be.

As for the details of Zhao Dazhui, how can Zhang He, who is a veteran of Yunzhou, not know?

It's not bad if you don't expose you, you're still rubbing your nose and face.

Although Zhao Dazhui is pretending, this clairvoyant is really easy to use, and Zhang He is a little reluctant.

With this thing, it will be much easier to observe the enemy situation in the future, and if you look at the high ground, you will be able to know the situation of the enemy army for three or four miles.

"Sledgehammer, let's discuss something!"

Zhang He said mysteriously.

What's up?

The pretending career was interrupted by Zhang He, and Zhao Dazhui was a little unhappy.

Zhang He coughed and said, "Look, my brother is working very hard outside, chasing the boat and observing the situation. Can you borrow this thing from me first? ”

As soon as the words fell, Zhao Dazhui pulled the clairvoyant back.

Don't!

Zhao Dazhui snorted and said, "This is a treasure of the immortal family, how can you have it as an ordinary person?" Besides, this thing is very scarce, and there are only two in Yunzhou now, so in order to cooperate with this operation, the lord asked me to bring one. You also know that our artillerymen need this clairvoyant more than you do. ”

Good steel should be used on the cutting edge.

Two clairvoyants were made, Guo Jia kept one for himself, and the other was given priority equipment to the artillerymen.

With this clairvoyant, the artillery command is like a tiger with wings.

I see!

Zhang He was a little disappointed, but still expressed understanding.

They don't have clairvoyance, and at most it's harder.

If the artillery loses clairvoyance, the power will naturally be greatly reduced.

But......

Zhao Dazhui changed his words and said with a smile: "You don't have to be anxious, the lord said, this thing can be mass-produced in the future, and each commander has one." ”

That's great!

Hearing this, Zhang He was relieved.

With this thing, who in the world is still the opponent of the Yunzhou Army.
