Wobasi said: "We all know this, where is the plan?"

Zhang Muchun said: "We still need to sail on the Black Sea for at least two days. During these two days, the Ottomans will definitely know that the coming people are evil, so they will take the following actions."

"First, blocking the Bosporus is nothing more than iron chains and artillery on both sides. For this, our Third Fleet can send four new Baturus to explore the way ahead."

"These four new Batulus are extremely thickly armored, and the highest position of the chimney is only slightly higher than the fort. In addition, the forts are all on the first deck, so they can attack all targets on both sides of the strait while traveling."

"Two-thirds of the strait is surrounded by cliffs on both sides, but the highest point is only more than a hundred meters. Whether they use artillery to attack from a low position or use trebuchets, they will have little impact."

"If the attack is from a high place, raise the elevation angle and use grenades and shrapnel bombs to carry out fixed-point strikes. If the attack is from a low place, just strike flatly."

"The focus of Istanbul's defense for hundreds of years has been around the castle. As for the strait, it has never been the focus. It is impossible to deploy too many artillery, and the castle cannot be built too strong or too thick."

"The thickest ones are naturally those in the narrowest places, such as Fort Meli and Fort Anatolia, but their walls are only three meters thick, and our country's 18cm armor-piercing howitzers can still cause damage to them."

"As for the iron chain, it's not a problem. Among the four new Batulus, there is still a special battleship. In addition to being used as a battleship, it also has sharp and thick ramming angles that can easily cut off the iron chain."

"The Ottomans didn't have machinery, so it was impossible for them to pull the iron chain straight. What we were most afraid of was the rebound force after the iron chain was cut off, especially the impact on the chimney. But because the Ottomans couldn't pull it straight, it contained

The rebound force will not be very strong, and most of the iron chains are arranged underwater to make it difficult for people to guard against."

"The rebound force is even smaller under the resistance of water, so there is no need to worry about this section."

"There is also the fire attack. We are all armored ships, but they are still helpless."

"When we arrived near the Golden Horn, due to the wide sea surface, the artillery of Úsküdar on the opposite side could not threaten us at all. At this time, we only need to have a big battle with the enemy navy nearby to completely block the strait and prevent the enemy from letting the strait pass.

Reinforcements from Asia Minor arrive in Istanbul"

"Then there is the matter of building a dock on the west coast of the strait. Under the superior firepower, we can quickly occupy a position on the shore, and then the infantry carrying mortars and short-barreled artillery can quickly build blocking positions."
p>

"About ten miles away from the Golden Horn, there is a place about three miles long that is actually a natural harbor. There are usually flat-bottomed boats docking there, but the Sultan is afraid that the enemy will come up from there and prohibits them from docking here."

(He was talking about the area near Dolmabahce Palace in later generations)

"After occupying this place, on the one hand, we built a blocking position to the west of the port, and on the other hand, we accelerated the construction of the port. Eight Batulus then went out of the strait, waiting for an opportunity to fight the enemy."

"Most of the enemy's main warships are docked near Port Pendik on the east side of the Sea of ​​Marmara. According to information provided by the intelligence department, they do have at least eight wooden steam warships and at least thirty large galleys waiting for us to arrive.

Near Haikou, if there are no accidents, they will definitely come out to fight."

"Once the enemy's navy is defeated, since the Black Sea is basically controlled by our army, there is no need to worry about the rear. We can send an armored fleet out of the Sea of ​​Marmara to sweep the Ottoman ships docked in nearby ports.

”

"After establishing a shore position on the west bank of the Bosporus, the army can be unloaded. One division will hold the position and attract nearby enemies to attack, while two divisions will attack and advance, one attacking southward along the strait, and the other

Attack on the perimeter"

"With three divisions as escorts, we can allow three engineer battalions to go ashore to repair the road to Galata Fort so that our field cannon can be transported to Galata Fort. The walls of Galata Fort are about one foot thick, which is still very high.

It is strong. Only by taking this fort can it be possible to move the field artillery to the top of the city to bombard the opposite city of Istanbul."

"After destroying the artillery on the other side, use the Batulu to cut off the iron chain blocking the Golden Horn Bay. At this time, with the cooperation of our warship artillery in the Golden Horn Bay, we can devote about one division to the attack.

The fighting outside Istanbul comes up"

"It is estimated that it will take three days to reach this point. It also depends on whether the attack near Galata Fort goes smoothly. There is only one standing brigade near Galata Fort. It is not our opponent at first, but the vastness all the way to the Black Sea is nearby.

The local area can also mobilize an army of 10,000, but it will still take some effort to completely eliminate it."

"Once we make good progress, about half a month later, the enemy will definitely draw troops from Europe. At this time, His Majesty's Guards can be dispatched. They will land at the Port of Burgas in Bulgaria and then guard it with one division.

At the port, the other two divisions attacked and advanced."

"At this time, the Ottomans have Austrians outside, Guards in the center, and an army near Istanbul. Their strength is definitely not enough."

"At this time, the siege can be carried out step by step. At the same time, the Persians in the east should also launch an attack. Their Ankara legion will not be able to get through. Even if it does, it will not be able to cross the Bosporus. It can only be in despair."<

"..."

......

Two days later, Chu Feng led four new Batulus into the Bosporus.

In fact, he was the commander of the Third Fleet, but he handed over the command because Navy Commander Deng Quan personally took charge. As for Shen Muhan, he was the commander of the Second Fleet.

However, the main battleships of the squadron are these four Batulus. The flagship Bogda is only used at critical moments. As for Tengis and Saiyin, they are auxiliary battleships. He actually commands the four Batulus.

This is the vast majority of the combat power of the Third Fleet.

Along the way, Chu Feng was still feeling a little uneasy. This time they did not walk along the coastline, but walked openly in the middle of the strait. The catapults were also carefully prepared for the artillery that might appear on both sides of the strait, but until

When they walked near Fort Rumelli, they didn't find anything unexpected.

However, there were small strongholds on both sides of the strait in twos and threes that bombarded them, but they were all small cannons made by the Ottomans themselves. For the rough-skinned and thick-skinned Batulu, they were no more than itchy. Without exception, these strongholds were bombarded by four Batu ships.

Lu destroyed them all by name.

But the situation is different when we arrive near Fort Rummeli.

This is a shore fortress built across the bank, and there are various types of artillery close to the fortress.

At present, two Baturus are responsible for the Anatolian Fort on the east coast. The two Batulus are dealing with the Anatolian Fort. They each have two doors with a diameter of 18 centimeters, which can load a giant fifty kilogram.

Armor-piercing grenade.

Then, four Baturus braved intensive artillery fire and began bombarding the two fortresses.

Comparatively speaking, Fort Rumei on the west coast was stronger, and Chu Feng personally led two Batulus to attack it.

The 18-centimeter cannon on the right is aimed at the city wall of Fort Rumelli a few hundred meters away, while other artillery pieces are aimed at the city head and the artillery positions on both sides of the castle.

"Boom..."

The distance of a few hundred meters is really easy for the current Truchin artillery, and a giant howitzer weighing fifty kilograms came out of the barrel!

This is a strait, and the water flow is stable. Most of Batulu's ship-based artillery are rifled guns, especially those over thirty kilograms. The artillery shells fly in a high-speed rotating attitude. If it is an ordinary smooth-bore round solid bullet, due to the

Its rotation at the moment it comes out of the barrel is uncontrollable, and its flight trajectory is naturally uncontrollable.

The hit accuracy is naturally greatly reduced.

However, it is different for a rifled gun with a mirror or a rifled gun with a tapered shell. When it comes out of the barrel, the interference from the outside wind direction and air pressure is almost negligible due to its strong initial velocity.
p>

Moreover, after the round solid projectile is ejected from the chamber, due to its own resistance and irregular rotation, the height will drop every time it flies, but the rifled conical shell is different. It can almost hit the set target at a certain distance.

The only difference from the real howitzers of later generations is that the initial speed, range and impact effect of the shells are different due to different ammunition powers.

So, the first giant cannonball fired by the Batulu hit Fort Rumelli!

Driven by the high-speed rotation, the cannonball instantly penetrated the stone city wall!

After it is rotated in, the stone will be broken immediately. If it is an ordinary grenade, it will explode the moment it touches the city wall. If it is not rotated in at high speed, then the shell will only rotate in a small part before exploding.

, mostly just the armor-piercing parts.

In either case, the effect is not good, but the rifled armor-piercing bullet is different. When it is screwed in, the surrounding stones will break in an instant, so the moment it touches the stones, it will not touch the bullets behind it.

Body part.

Instead, it will spin further in. Even so, it will still explode when the armor-piercing part is screwed in for a distance of about one meter, because the further it goes in, the greater the resistance it encounters.

But this is enough.

The weight of the armor-piercing part of a fifty-pound artillery shell is about the same as the weight of the projectile body, which means that after drilling one meter, there is still about twenty-five kilograms of the projectile that explodes!

For example, the wall of Fort Meili is about three meters thick. This shell immediately caused a large area of ​​​​collapse near the strait!

Then it will be a matter of time before it completely collapses.

In other directions, under the covering blows of Batulu's other 12-centimeter and 15-centimeter howitzers and shrapnel shells, the enemy's firepower was suppressed in one encounter.

About half an hour later, the section of Fort Merrill facing the strait completely collapsed!

Large chunks of white stones fell hula-la-la-la-da towards the strait, causing large waves of waves from time to time.

An hour later, almost all the walls on the side of the Anatolia Fort facing the strait collapsed!

Under the saturation coverage of other artillery, there were probably very few soldiers left in the city. At this time, under the cover of artillery fire, a Marine Corps battalion disembarked from each Batulu.
Chapter completed!
