At the same time that the 1st Division of the Red Guard Army captured Vladivostok and attacked the headquarters of the Japanese Third Army, the main ships of the 3rd Fleet of the Red Guard Navy quietly approached the Uraga Waterway at the entrance to Tokyo Bay at night.

The Uraga Waterway is the first waterway to exit the Pacific Ocean in front of Tokyo Bay, and it is also an important line of defense for the gateway to the Japanese capital.

Entering from the Uraga Waterway is Tokyo Bay.

By the time the Third Fleet had quietly arrived, Tokyo, Japan, had not yet received information about Heihachiro Togo and the Combined Fleet.

The vanguard of the Third Fleet provides support for the advance of the capital ship group, and all ships encountered along the way will be secretly controlled to ensure that no information is leaked.

In the middle of the night, the Third Fleet, with the help of night and dense fog at sea, quietly passed through the Uraga waterway.

If it weren't for the limitations of technology in this era, the Third Fleet would not have entered Tokyo Bay so easily.

After all, there are no radios, no radars, sonars and other equipment, and at night, in the wide waterways of Uraga, the Japanese simply cannot monitor in real time.

In addition, during the day, the waterways were busy, and there were no mines and other defensive facilities, so the Third Fleet was extremely easy to enter.

The Third Fleet, which quietly entered Tokyo Bay, was still very careful, the dense fog weather gave the Third Fleet the best cover, and in the middle of the morning, the channel of Tokyo Bay was in the quietest state.

In addition, the Japanese Combined Fleet took away all the warships of the Japanese Navy, and there were only a few torpedo boats in the entire Tokyo Bay, and there were no other sea ships that could fight.

The Third Fleet, which entered Tokyo Bay, did not go directly in the direction of Tokyo, but after entering Tokyo Bay, it went directly to Yokosuka.

Yokosuka is the largest port in the Far East today, much larger than Vladivostok, where the Russian Pacific Fleet is stationed, and is one of the few natural deep-water ports in Japan.

Located on the east coast of the entrance to Tokyo Bay on the island of Honshu, Yokosuka Port is connected to Yokohama City to the north and the east coast of Yokosuka City to the south.

Although all the main warships of the Japanese Navy during this period were ordered from European countries, Japan has always been developing its own shipbuilding capabilities.

Cultivating skilled shipbuilding workers is a necessary condition for Japan to make every warship order in Europe, learn advanced shipbuilding technology from European countries, and develop its own shipbuilding industry at the same time.

Forty years ago, during the Edo shogunate, Japan built its first shipyard in Yokosuka, and nearly half a century has passed now, and the first shipyard in Japan, the Yokosuka Naval Yard, was expanded in Yokosuka the year before last.

The current Yokosuka Naval Works already has the ability to build armored cruisers and battleships, giving Japan the ability to develop a strong navy on its own.

And because of the existence of the Yokosuka Naval Yard, the port of Yokosuka has also become the largest naval base in Japan, where all the warships of the Japanese Combined Fleet are repaired, maintained, and repaired, and most of the warships in the Combined Fleet, except for battleships and cruisers, are also built here.

Yokosuka is the base camp of the Japanese naval fleet, and it is also the most important link in the defense of the capital Tokyo, and the Tokyo Defense Fortress Command is located in Yokosuka, and many army units are stationed.

At this time, Yokosuka was not a city with few civilians living there, but a fortress with a large number of barracks, a professional naval academy, and a battery on the commanding heights along the coast.

Although Yokosuka does not have the scale of World War II and the style of the first naval base in the Far East after the end of World War II, it has begun to take shape on an industrial scale, and with this place, the Japanese Navy has the possibility of recuperation.

The necessity of Yokosuka's strike, measured at a tactical level, surpasses Tokyo's.

Fan Yize looked down on this family background in Yokosuka, Japan, and the factories that Japan had worked so hard to build, destroying the combined fleet, and then extinguishing the last bit of hope for the Japanese navy, which was just a piggybacking thing.

The fleet in the night slowly approached Yokosuka, and the Japanese navy and army and battery defenses in Yokosuka were still relaxed.

Although Japan does not yet know the information of the Combined Fleet, the Japanese government knows that the Russian Second Pacific Fleet is heading in the direction of Vladivostok.

The army had drawn too many troops in Korea and Siberia, and in fact, here in Yokosuka, the Japanese army had a single wing of troops left, and most of the naval barracks were empty.

The precautions were there, but the level was not high, and most of the Japanese defenders in the Yokosuka fortress were also asleep.

No one would have thought that Yokosuka would be attacked, and most of them were relaxed, and their hearts were worried about the news of the Combined Fleet.

When the Third Fleet came within range of the attack on Yokosuka, a kilometer away from Yokosuka's six main batteries, several lurking Red Guard soldiers, carrying radio stations, prepared to direct the attack of the ship's guns.

The three dreadnoughts of the first class battleship, close to the distance of about 6,000 meters from Yokosuka, can faintly see the lights of the Yokosuka Naval Yard, which has no rest at night, is still busy.

The roar of the ship's guns erupted on the sea, and a large number of Japanese workers in the shipyard stopped their work.

"Yamamoto-kun, did you hear the sound of cannons just now?"

"I heard it, but where did the cannon sound come from?"

A few seconds later, the roar of cannonballs, the whistling of falling shells in the sky, completely shattered the silence of the shipyard.

The workers in the shipyard looked up one after another, and the tracer shells dragged in the sky were clearly visible, and the Japanese shipyard workers, who had never experienced such a thing, were all at a loss.

The whistling shells fell, and the violent explosion sounded around the batteries around Yokosuka, and the huge explosion Tokyo and the flames made Yokosuka completely wake up, and tens of thousands of Japanese shipyard workers, as well as students and soldiers of the academy, woke up from the bed one after another.

Heavy artillery fire shook the entire Tokyo Bay, and even Yokohama could hear the sound of explosions coming from Yokosuka.

In the six batteries in Yokosuka, the Japanese soldiers did not have time to put on their clothes, and hurriedly prepared to return fire.

The Russians are coming, this is the first thought in the minds of all the Japanese, and the only thing left is to fight back.

Yokosuka, with six reinforced concrete forts, has the power to bring the attackers home.
