The Galata fortress fell into the hands of the Tang people, and then divided the Golden Horn with the Byzantines, cut off the large iron cable between Constantinople and the iron cable, and the iron cable sank to the bottom of the sea!

The people on the Tang gunboats were overjoyed, but Li Baodong, the commander of the naval division, was very calm, and first sent two sentinel boats to investigate the waterway.

As a result, his M's, shallow-water small gunboat actually bottomed out and ran aground!

The Byzantines were very cunning, they actually sank the bottom early with sand and gravel and scrap ships, and they did not know how much material they threw to block the channel at the exit of the Golden Horn, so that the Tang ships could not enter the Golden Horn, and could not play the effect of attacking from three sides (the Golden Horn is to the north, the strait to the east, the Sea of Marmara to the south, and the southeast and southeast sides are already the world of the Tang ships).

Emperor Tiberius III was a little level, he knew the power of the Tang army's gunboats, how could he not be wary of one or two, he made preparations in advance, and pretended to seal the sea with iron cables, in essence, he did something under the surface of the sea!

Seeing the two Tang boats moored crookedly on the water, the sailors rushed to get off the boats and flee for their lives, and the Byzantines cheered loudly: "Hahaha, these fools!" ”

The role of capturing the Galada fortress was greatly weakened, the Tang army's artillery was mounted on the fortress, and the cannon was fired across the Golden Horn, and the cannonball reached the opposite city wall at the end of the crossbow, and the Tang army officer clearly saw that the other party actually had someone to catch the bullet with his hand!

It's also successful!

Seeing the depressed appearance of his subordinates, Li Baodong said hesitantly: "Yesterday we blocked the sea, today we entered the Golden Horn, we went from one victory to another, we didn't lose!" ”

Everyone was right when they thought about it, and in reply to laughter, Li Baodong ordered: "Prepare the transportation boat, I will go and report to the governor!" ”

The governor Razakhan only said that he had taken the Galata fortress and nothing else, of course, he had to give credit to the sailors.

……

"Report, my sailor has captured the Galata Fortress by order of the general, and now I will reply to the commander's order!" In the handsome tent, Li Baodong said loudly.

Everyone had strange faces, they already knew about the blockage of the mouth of the Golden Horn, and what was the use of capturing the Galata fortress but not achieving the desired goal!

"I ordered the sailors to fire their guns 24 hours a day, so that the Byzantines were upset, distraught and afraid, and our gunboats did not work in vain!" Li Baodong said loudly.

This is very familiar!

All the generals looked at the governor Lazahan, thinking that the navy was a cow, and the special troops had a big temper, so they dared to fight against the governor, and they had a spear to return to the shield.

Lazahan remained silent and praised Li Baodong's decisive attack for achieving the intended goal, capturing the Galata fortress, and our army approached the Golden Horn and isolated Constantinople, which is not a small credit!

Write down the next merit first, and then reward the merit later.

Li Baodong was satisfied, and stood with his head held high.

"How's the stranded Kaido? Can I cross the boat? ”

"Not passable!" Li Baodong explained his reconnaissance situation, it turned out that the sediment was mostly made of boulders, which was difficult to salvage, that is, it could not dredge the channel, even if it was an infrastructure maniac like the Tang people.

While the army was discussing how to attack Constantinople, everyone felt that it was tricky, and there were guards outside, holding a tray with a purple bag embroidered with a fierce golden flying tiger, and he reported: "The prince sent someone to send the bag." ”

"What is the will of the prince?" Razakhan asked urgently.

"I didn't have any intentions, I just sent a bag!" The guard replied.

Ace in the hole?

Learning from Cao Cao and Zhuge Liang's way, everyone looked at the bag with interest.

The results did not disappoint them!

Razakhan politely bowed to the bag as a sign of respect, then opened it and took out a silk book to read.

Only Cheng Boxi was qualified to watch with him in the tent, and the two watched together, and their eyes burst out with surprise and joy.

Lazakhan himself read the silk book and said: "The prince taught us how to get the ship into the Golden Horn!" ”

He told Wei Xi's method, which amazed everyone.

“…… On the north side of the Galata Fortress, a land trough was laid, made of thick wooden planks, and the bottom of the trough was coated with a thick layer of beef and sheep fat, and the ships were dragged into the Golden Horn! ”

……

As soon as it was said, the ship took a large number of engineers, civilians and planks, rushed to the Galata fortress, and after landing, began to work quickly!

They worked from day to night, but when they saw the lights shining brightly and reflecting the sky, the Byzantines were secretly frightened!

The Tang Army's engineers and civilians worked together to use wooden planks and big nails to nail a kilometer-long wooden ship trough in one day and one night according to the terrain.

At the same time, the sailors and technicians of the Tang Army, together took off everything that could be removed from their gunboats: artillery, shells, supplies, armor guards on the hull, sails and ......, and then tied the hull with thick ropes, mobilized hundreds of people, and dragged them together!

It was not only the soldiers who participated in the hands-on, but only the officers who had a little strength, who also took off their uniforms, put fur on their backs (to protect their skin), and dragged them vigorously.

Hi yo...... Hey!

Hard, come on, 123!

The hull of the ship did not move at first, and then, with the efforts of everyone, it slowly left the water and moved towards the shore little by little.

But at the moment when it was completely out of the water, it was as if the sea did not want the ship to leave, and the rope broke!

The boat fell back into the water in an unstoppable position!

Bang!

The sea water was surging, and the "slender men" fell to the ground like a rolling gourd.

Many people were injured and screamed, many people had abrasions on their hands and feet, and some people even broke their legs.

Looking at the ripped rough rope, everyone gasped.

What are you doing with this ship, it's so big and so heavy!

Tang ships were generally larger than foreign ships, and these ships were reassembled at the seaside.

What to do?

Top hard!

The craftsmen brainstormed: the rope could not be thickened, otherwise the hands would not be able to grasp it.

"Easy, just add wire to the rope!" There was an old craftsman who said.

Aha, the Tang people evolved to the point where the wire appeared!

Iron wire is a kind of metal wire made of iron drawing, it has a very large role, used in industry, agriculture, breeding, transportation, mining and other fields, and is also used a lot in daily life, such as pulling iron wire to dry clothes.

The reason why iron wire came out is that there is also an important application promotion, that is, the construction industry, but Wei Xi's old business.

It is a very common usage in construction to hoop steel bars.

It was used militarily to guard and delay the enemy's attack, and it played a great role, but the Tang army occupied an offensive position, the strategic space was vast, and the cavalry came and went like the wind, and the enemy could not reach it, so it did not show the power of barbed wire.

Now, with the addition of wire to the rope, the tension is greatly increased and is not broken. Everyone regained their strength and tuged the boat hard.

The first boat got out of the water, leaned its hull, followed the trough, and headed for the Golden Horn!
