Back in time, at the same time as the Russo-Japanese Battle of Tsushima broke out, the battle for Vladivostok also resumed.

At the Battle of Shuangchengzi, the victorious Japanese Army, after a brief rest, carried out a final attack on Vladivostok.

The Japanese Army, which controlled the 356 heights, had the commanding heights and was able to calibrate the artillery and attack the main defensive pillboxes inside the fortress.

Under the blow of Japanese siege artillery, in three days, Russia lost almost all its main defensive fortresses, and a large number of machine-gun fire points were also removed, leaving only those trench lines in Vladivostok.

Three thousand Russian soldiers, who continued to hold out under artillery fire, were all convinced that the navy would come to the rescue of Vladivostok and would kill all the damned Japanese.

It's just that no one knows whether they will really be able to hold out until the fleet arrives in Vladivostok.

On the other hand, the Japanese Third Army did not rush to send soldiers to attack, and patiently cleared the defenses in Vladivostok with artillery, and for three consecutive days, no Japanese soldiers appeared in front of the Russian soldiers.

But because of this, the hearts of all Russian soldiers became heavier and heavier.

By this time, the remnants of the Russian soldiers had little morale, pillboxes were blown up one after another, and the smell of surrender was permeating the trenches.

Xu Yanwu led a fully formed infantry division, and after several months of preparation, he also quietly concentrated in the rear of the Vladivostok battlefield.

Less than twenty kilometers from the artillery positions of the Japanese Third Army, they were hidden in the woods, quietly waiting for the opportunity to come.

In this forest in the eastern part of Vladivostok, a cave was dug to serve as Xu Yanwu's headquarters.

In the headquarters, a simulated sand table of Vladivostok was built, and with the artillery fire of the Japanese Third Army in the past few days, the marks of the vladivostok fortress on the sand table were pulled up.

Now, there are less than ten pillboxes left in the Vladivostok fortress on the sand table, and it is estimated that in two days, these ten pillboxes will also be killed.

This made Xu Yanwu inevitably feel slightly anxious, and the news from the command center that the fleet had no sign of departure.

And beside him, there was only one combat unit of an infantry division, there were no heavy weapons such as artillery, and the most powerful firepower was only machine guns.

If there is no news tonight, Xu Yanwu can only take the risk of sending troops, take advantage of the night, seize the 356 heights, and directly capture the fortress of Vladivostok, and then directly face the Japanese Third Army.

As long as they can hold out until the fleet destroys the Japanese combined fleet and goes north to Vladivostok, then the Japanese will not be able to attack Vladivostok.

The defense of the Vladivostok fortress was built on three points, the outer harbor was blocked with mines, which could block the attacking enemy, and the fleet, which was in the inner harbor, was able to directly support the fortress in battle.

Under normal circumstances, if you want to attack Vladivostok, you will face the firepower inside the Vladivostok fortress and the heavy artillery of the warship.

So the Russians never worried that the Vladivostok fortress would be captured, and it was not until World War I and World War II, after the appearance of the air force on the battlefield, that the Vladivostok fortress really became the first fortress in the Far East.

At this time, the Vladivostok fortress was not too strong, and after 1912, Vladivostok's defense was called strong, and even if it was a Japanese army of 300,000 at that time, even if Vladivostok did not have naval support, it was extremely difficult to storm it.

Now Vladivostok is already in a storm, without the support of naval guns, the commanding heights have been captured, and the fortresses in the fortress have been uprooted one by one, and they will be breached at any time.

Seeing that it was difficult for the Russians to continue to hold on, Xu Yanwu also had to make a decision to capture Vladivostok in the next two days, depending on the situation.

Wait for the Navy to come, take out the artillery positions of the Japanese, and then hold Vladivostok.

It's just that it's very risky to do this, although Xu Yanwu is very confident in his soldiers, he will definitely be able to wait until the fleet comes, but he knows better than anyone that in the absence of artillery suppression, in the face of the Japanese Third Army with 30,000 troops, even if he can hold on, he will pay a lot of casualties.

But once that time comes, it will be easier than fighting for this fortress from the Japanese.

In the midst of Xu Yan's troubles, night fell, and the artillery of the Japanese Third Army began to rest.

The shelling during the day was only intermittent, with no intensity or density to speak of, and the Japanese side actually had no intention of storming Vladivostok.

Everything will have to wait for the news of the combined fleet to come before making a decision.

However, for the Russian defenders in the fortress, the pressure must not be relaxed, and maybe the Russians in the fortress will surrender in the next second.

Therefore, while maintaining a certain artillery strike, the Japanese Third Army was only camped in the fortress, and did not even have the intention of encircling the fortress.

However, the Japanese Third Army did not know that just tonight, Xu Yanwu received the news that he had been waiting for for a long time.

The fleet moved, and soon the news of the actions of the three fleets came in a steady stream.

The next morning, as soon as the sky was bright, Xu Yan woke up from a nap and received the news that the Japanese Combined Fleet had been completely wiped out and the First Fleet had come to Vladivostok.

And last night, when the fleet was engaged in a battle with the Japanese Combined Fleet, a minesweeping formation that came out of the chrono portal was already heading towards Vladivostok.

General Xu smiled, looked at the sand table in front of him, and gave the order to assemble the troops.

It is expected that in a few hours, the minesweeper will reach Vladivostok and begin to clear the waterways of the port.

But it didn't matter if the mines were not cleared, because the fleet was able to shell the Japanese artillery positions outside the Vladivostok fortress from the Amur Bay.

Vladivostok Fortress is located in the southernmost part of the Amur Peninsula, the whole peninsula is basically northeast-southwest trend, the southwest is sharp and narrow, east, west and south facing the sea, the east is bordered by the Golden Horn Bay of Peter the Great Bay, the west is bordered by the Amur Bay and Sports Bay, and the south is bordered by Peter the Great Bay and the Russian Island.

The inner harbor of the Vladivostok fortress, the Bay of Peter the Great and the Golden Horn, has been blocked by mines by the 1st Pacific Fleet of the Russian Navy.

Surrounded by hills, the fortress did not worry about warships shelling the fortress from the Amur Bay, but in front of the fortress, it was a smooth road.

As long as the warships are close to the coastline from the edge of the fortress, they will be able to cover the area with firepower.

This is also the reason why the Vladivostok fortress was not actually built on the edge of the bay, and the reason for the existence of the Vladivostok fortress was to prevent the enemy from attacking from the direction of the Amur Bay, and also to defend it in the rear of Peter the Great Bay.
