Just as the Russian Navy was heading to Vladivostok after resting from Cam Ranh Bay, the commander of the Japanese Combined Fleet, Heihachiro Togo, also concluded that the Russian fleet would go directly to Vladivostok through the Tsushima Strait, based on the supply situation of the Russian fleet.

On May 25, 1905, a supply ship flying the Russian flag sailed into Shanghai.

As a result, the Japanese Navy decided that the Russian fleet must be in the nearby waters, so it stepped up preparations for war.

The Russian fleet from the east, because Port Arthur had fallen into the hands of the Japanese, could only sail to Vladivostok, and there were two routes to Vladivostok: either through the Tsushima Strait into the Sea of Japan, or through the Soya or Katsu Straits, and from the vicinity of Hokkaido.

Heihachiro Togo judged that Rozdvinsky would definitely take the Tsushima Strait, so he concentrated the combined fleet on the Tsushima Islands and the bay of Korea, waiting for the arrival of war, and Togo sent 4 armed merchant ships and 2 old cruisers to reconnoiter in the East China Sea.

So Heihachiro Togo ordered the whole fleet to enter the battle position and wait for the arrival of the Russian fleet.

It was at this time that the Russian fleet began to depart from the vicinity of Taiwan, reaching the vicinity of Shanghai on May 26, 1905, and entering the Tsushima Strait in the early morning of the 27th, followed by a crucial naval battle.

In the early morning of May 27, 1905, the armed Japanese merchant ship Shinano Maru discovered a medical ship in the Russian fleet.

After careful deliberation, Shinanomaru sent a telegram discovering that the Russian fleet was sailing northeast at location 203, and the 3rd, 4th, 5th, and 6th Sentai of the Japanese Combined Fleet, under the leadership of Vice Admiral Shigehiro Dewa, Vice Admiral Kuayu Wakichi, Vice Admiral Shichiro Kataoka, and Rear Admiral Togo Masaji, respectively, concentrated in the direction of the Russian fleet.

Aboard the Japanese battleship Mikasa, anchored in the bay of the town, Heihachiro Togo ordered the entire army to be dispatched.

The cruiser Izumi of the Japanese Sixth Sentai made contact with the Russian ship and reported a position of 48 km northwest of Ukushima in a northeasterly direction.

On that day, there was a thick fog on the sea, and it was not easy to identify the Japanese warships painted all gray-blue, but the bright yellow painted chimneys on the black hulls of the Russian ships became obvious targets, and the Japanese cruisers had been monitoring the movements of the Russian ships from a distance without relaxation.

But just when the Japanese cruisers thought that the Russian Navy would not open fire at the moment, the battleship Orel opened fire on the Japanese cruiser that was tracking, and then continued to fire under the order of Rozdvinsky, so that before the war began, the Japanese Navy had already lost a cruiser.

Then Togo ordered the whole fleet to attack, 1 hour later the Japanese fleet began to follow the Russian fleet forward, at 11:15 p.m. the two sides had a tentative exchange of fire, the rest of the Japanese fleet was always accompanied by the Russian fleet like a ghost, the Japanese fleet was also a little panicked when the Japanese fleet first appeared, but then it returned to normal, and Rozdvinsky also let the fleet enter a state of imminent battle at the first time to prevent the Japanese sneak attack.

At 1:30 p.m., the war between Japan and Russia approaching 10 nautical miles began.

At 1:55, Togo Heihachiro imitated Nelson during the Battle of Trafalgar, and issued a signal of "the rise and fall of the imperial kingdom in this battle, and all members of the team will work hard", and then in order to obtain a favorable attack position, Togo Heihachiro resolutely ordered a big turn in front of the enemy, using all the firepower on the side to meet the bow fire of the Russian army, but Rozdvinsky did not make Togo Heihachiro get his wish, but let the fleet turn to the right to the fire point of Togo Heihachiro, which was bypassed.

However, Rozdvinsky's move did not make Togo Heihachiro give up, so Togo Heihachiro began to use his side's speed advantage to turn to the left in an attempt to gain priority again.

In response, Rozdvinsky was also trying to gain a favorable fighting position for his side, but after a series of orders from the supreme commanders of both sides, neither side was able to gain the superior position as desired.

A series of orders instead brought the fleets of both sides closer and closer, and seeing that the fleets began to approach but did not gain an advantageous position, the battle could only begin in a melee.

In the ensuing hours of naval battles, both Japan and Russia suffered heavy losses.

When the melee began, Togo ordered the ships to turn to the port side at 16 o'clock, which surprised both the Japanese officers and the Russian fleet, because in this way, the ships that turned behind would only hinder the shooting of the ships that were not turning, and that turning point made the Japanese ships that were turning a target for the Russian ships.

At this moment, Rozdvinsky seized the advantage and ordered the ships to open fire one after another, the Japanese ships still turned in turn and were attacked by the Russian ships, the Asama armored cruiser was hit by three shots in the stern, the steering gear failed to rotate, and then several shells were hit, one of which happened to hit its ammunition depot, and the Asama sank on the spot, and the other Japanese ships were also damaged to varying degrees.

After the turn was completed, the Japanese ships began to concentrate their firepower on the Russian Second Fleet, and its flagship Osilijabia was immediately hit, and the command of the Second Fleet, which was immediately lost, fell into confusion, but fortunately, Rozdvensky took over the command in time and ordered the ships to start a counterattack.

For some time after that, due to the mist at sea, the Japanese fleet lost the trace of Russian ships for a time, but sometimes recaptured the main force of Russian ships.

In the ensuing melee, the Russian First Fleet and the Second Fleet were successively hit hard by the Japanese, several warships were sunk and some warships were damaged and withdrew from the battle, and the most tragic thing was the flagship of the Second Fleet, Osrijabia, which was not originally a major injury after being hit, but the Japanese ships seemed to have seen the Osiriabia, resulting in the Osiriabia being sunk only fifteen minutes later.

Compared with the heavy damage suffered by the Russian fleet, the Japanese ships were not much better, the Asama was directly sunk at the beginning of the battle, and then the flagship of the combined fleet, the Mikasa, was also shelled, indicating that Heihachiro Togo lost command of the fleet for a period of time, and Rozdvinsky also seized the opportunity in time During this time, the Russian army sank six cruisers of the combined fleet, and three cruisers were also heavily damaged and withdrew from the battlefield.

In the ensuing melee, the Japanese ships of the 1st and 2nd Squadrons lost all the destroyers in the fleet, and in this case, Togo Heihachiro had to put the 5th and 6th Sentai into battle, and as soon as they entered the battle, the "Naniwa" and "Otowaba" were heavily damaged by the Russian army, but although they were heavily damaged, the situation was still saved by Togo Heihachiro.

At this moment, Rozhdvinsky saw that his side had lost its advantage, and immediately issued an order to break out, and after the order to break out, the ships began to break through, but they were still tightly bitten by the Japanese ships, and the Russian cruiser "Svetlana" was also sunk in the breakout until it was sunk.

An old cruiser "Donskoy" gave the Russian army hope of breaking through only after stubbornly resisting the siege of 6 Japanese cruisers.

After the breakout was carried out, most of the Russian fleet was chased and sunk by the Combined Fleet, but the Combined Fleet also paid the price of three battleships being sunk and most of the battleships were heavily damaged, and some of them were sunk after the battle.

After this battle, only seven warships of the Russian army successfully broke through, but in order to pursue the Russian combined fleet that broke through also paid a great price, it can be said that both sides of this battle were seriously traumatized, and the navies of both countries were all elite, if you want to recover, don't talk about it in five or six years.
