The Battle of Tsushima (Russian: Цусимское сражение, Tsusimskoye srazheniye), also known in Japan as the Battle of the Sea of Japan (Japanese: 日本海海戦, Hepburn: Nihonkai kaisen), was the final naval battle of the Russo-Japanese War, fought on 27–28 May 1905 in the Tsushima Strait. A devastating defeat for the Imperial Russian Navy, the battle was the only decisive engagement ever fought between modern steel battleship fleets[4][5] and the first in which wireless telegraphy (radio) played a critically important role. The battle was described by contemporary Sir George Clarke [f] as "by far the greatest and the most important naval event since Trafalgar".[6]

The battle involved the Japanese Combined Fleet under Admiral Tōgō Heihachirō and the Russian Second Pacific Squadron under Admiral Zinovy Rozhestvensky, which had sailed over seven months and 18,000 nautical miles (33,000 km) from the Baltic Sea. The Russians hoped to reach Vladivostok and establish naval control of the Far East in order to relieve the Imperial Russian Army in Manchuria. The Russian fleet had a large advantage in the number of battleships, but was overall older and slower than the Japanese fleet. The Russians were sighted in the early morning on 27 May, and the battle began in the afternoon. Rozhestvensky was wounded and knocked unconscious in the initial action, and four of his battleships were sunk by sunset. At night, Japanese destroyers and torpedo boats attacked the remaining ships, and Admiral Nikolai Nebogatov surrendered in the morning of 28 May.

All 11 Russian battleships were lost, out of which seven were sunk and four captured. Only a few warships escaped, with one cruiser and two destroyers reaching Vladivostok, and two auxiliary cruisers as well as one transport escaping back to Madagascar. Three cruisers were interned at Manila by the United States until the war was over. Eight auxiliaries and one destroyer were disarmed and remanded at Shanghai by China. Russian casualties were high, with more than 5,000 dead and 6,000 captured. The Japanese, which had lost no heavy ships, had 117 dead.

The loss of almost every heavy warship of the Baltic Fleet forced Russia to sue for peace, and the Treaty of Portsmouth was signed in September 1905. In Japan, the battle was hailed as one of the greatest naval victories in Japanese history, and Admiral Tōgō was revered as a national hero.[g] His flagship Mikasa has been preserved as a museum ship in Yokosuka Harbour.


Conflict in the Far East[edit]

On 8 February 1904, destroyers of the Imperial Japanese Navy launched a surprise attack on the Russian Far East Fleet anchored in Port Arthur; three ships – two battleships and a cruiser – were damaged in the attack. The Russo-Japanese war had thus begun. Japan's first objective was to secure its lines of communication and supply to the Asian mainland, enabling it to conduct a ground war in Manchuria. To achieve this, it was necessary to neutralize Russian naval power in the Far East. At first, the Russian naval forces remained inactive and did not engage the Japanese, who staged unopposed landings in Korea. The Russians were revitalised by the arrival of Admiral Stepan Makarov and were able to achieve some degree of success against the Japanese, but on 13 April Makarov's flagship, the battleship Petropavlovsk, struck a mine and sank; Makarov was among the dead.[7] His successors failed to challenge the Japanese Navy, and the remaining six Russian battleships[h] and five armoured cruisers [i] were effectively bottled up in their base at Port Arthur.

By May, the Japanese had landed forces on the Liaodong Peninsula and in August began the siege of the naval station. On 9 August, Admiral Wilgelm Vitgeft, commander of the 1st Pacific Squadron, was ordered to sortie his fleet to Vladivostok,[8] link up with the Squadron stationed there, and then engage the Imperial Japanese Navy (IJN) in a decisive battle.[9] Both squadrons of the Russian Pacific Fleet would ultimately become dispersed during the Battle of the Yellow Sea, where Admiral Vitgeft was killed by a salvo strike from the Japanese battleship Asahi on 10 August, and the Battle off Ulsan on 14 August 1904. What remained of Russian Pacific naval power would eventually be sunk in Port Arthur in December 1904.[10]


With the inactivity of the First Pacific Squadron after the death of Admiral Makarov and the tightening of the Japanese noose around Port Arthur, the Russians considered sending part of their Baltic Fleet to the Far East. The plan was to relieve Port Arthur by sea, link up with the First Pacific Squadron, overwhelm the Imperial Japanese Navy, and then delay the Japanese advance into Manchuria until Russian reinforcements could arrive via the Trans-Siberian railroad and overwhelm the Japanese land forces there. As the situation in the Far East deteriorated, the Tsar (encouraged by his cousin Kaiser Wilhelm II),[11] agreed to the formation of the Second Pacific Squadron.[12] This would consist of five divisions of the Baltic Fleet, including 11 of its 13 battleships. The squadrons, including the later-formed Third Pacific Squadron, departed the Baltic ports of Reval (Tallinn) and Libau (Liepāja) on 15–16 October 1904 (Rozhestvensky fleet)[j] and 2 February 1905 (Nebogatov fleet),[13] and the Black Sea port of Odessa on 3 November 1904 (armoured cruisers Oleg and Izumrud, auxiliary cruisers Ural and Terek, destroyers Gromkiy and Grozniy [k] under the command of Captain 1st rank Leonid Dobrotvorsky.[15]), numbering 48 ships and auxiliaries.[16][l]

Dogger Bank[edit]

The Rozhestvensky and von Fölkersahm squadrons sailed through Øresund strait into the North Sea. The Russians had heard fictitious reports of Japanese torpedo boats operating in the area and were on high alert. In the Dogger Bank incident, the Rozhestvensky squadron mistook a group of British fishing trawlers operating near the Dogger Bank at night for hostile Japanese ships. The fleet fired upon the small civilian vessels, killing several British fishermen; one trawler was sunk while another six were damaged.[12] In confusion, the Russians even fired upon two of their own vessels, killing some of their own men. The firing continued for twenty minutes before Rozhestvensky ordered firing to cease; greater loss of life was avoided as the Russian gunnery was highly inaccurate.[17] The British were outraged by the incident and incredulous that the Russians could mistake a group of fishing trawlers for Japanese warships, thousands of kilometres from the nearest Japanese port. Britain almost entered the war in support of Japan, with whom it had Anglo-Japanese alliance (but was neutral in the war, as their mutual defense clause stipulated "when either nation faced 'more than one' adversaries in a war"). The Royal Navy sortied and shadowed the Russian fleet until a diplomatic agreement was reached.[12] France, which had hoped to eventually bring the British and Russians together in an anti-German bloc, intervened diplomatically to restrain Britain from declaring war.[12] The Russians were forced to accept responsibility for the incident, compensate the fishermen, and disembark officers who were suspected of misconduct to give evidence to the enquiry.[18][19][20]

The draught of the newer battleships, which had proven to be considerably greater than designed,[22] preventing their passage through the Suez Canal[m] caused the fleet to separate after leaving Tangier on 3 November 1904. The newer battleships, cruisers, fast auxiliaries and the destroyers for protection, proceeded around the Cape of Good Hope under the command of Admiral Rozhestvensky while the older battleships and cruisers made their way through the Suez Canal under the command of Admiral von Fölkersahm. They planned to rendezvous in Madagascar, and both sections of the fleet successfully completed this part of the voyage.[22] The longer journey around Africa took a toll on the Russian crews under Rozhestvensky, "who had never experienced such a different climate or such a long time at sea" as "conditions on the ships deteriorated, and disease and respiratory issues killed a number of sailors".[20] The voyage took half a year in rough seas, with difficulty obtaining coal for refueling – as the warships could not legally enter the ports of neutral nations – and the morale of the crews plummeted. The Russians needed 500,000 short tons (450,000 t) of coal and 30 to 40 re-coaling sessions to reach French Indochina (now Vietnam), and coal was provided by 60 colliers from the Hamburg-Amerika Line.[n] By April and May 1905 the reunited fleet had anchored at Cam Ranh Bay in French Indochina.[o][16][28]

The Russians had been ordered to break the blockade of Port Arthur, but the battleships in the port were sunk by the Japanese land artillery, and the heavily fortified city/port had already fallen on 2 January just after the Second Pacific Squadron arrived at Nossi Be, Madagascar, before the arrival of the Fölkersahm detachment. The objective was therefore shifted to linking up with the remaining Russian ships stationed in the port of Vladivostok, before bringing the Japanese fleet to battle.[29]

The Russians had three possible routes to enter the Sea of Japan and reach Vladivostok: the longer were the La Pérouse Strait and Tsugaru Strait, on either side of Hokkaido. Admiral Rozhestvensky did not reveal his choice even to his subordinates until 25 May, when it became apparent he chose Tsushima by ordering the fleet to head North East after detaching transports Yaroslavl, Vladimir, Kuronia, Voronezh, Livonia and Meteor as well as auxiliary cruisers Rion and Dniepr with the instruction to go to the near-by neutral port of Shanghai.[30] The Tsushima Strait is the body of water eastward of the Tsushima Island group, located midway between the Japanese island of Kyushu and the Korean Peninsula, the shortest and most direct route from Indochina. The other routes would have required the fleet to sail east around Japan.[p] The Japanese Combined Fleet and the Russian Second and Third Pacific Squadrons, sent from the Baltic Sea now numbering 38, would fight in the straits between Korea and Japan near the Tsushima Islands.[30]

Because of the 18,000-mile (29,000 km) journey, the Russian fleet was in a poor condition for battle. Apart from the four newest Borodino-class battleships, Admiral Nebogatov's 3rd Pacific Fleet consisted of older and poorly maintained warships.[32] Overall, the Japanese side had a maneuvrability advantage. The long voyage, combined with a lack of opportunity for maintenance, meant the Russian ships were heavily fouled, significantly reducing their speed.[33] The Japanese 1st Battle Division could exceed 18 knots (33 km/h) and regularly maneuvred at 15 knots, but the Russian fleet included warships with the maximum speed of 14 to 15 knots (with new engines/boilers, normal load, and clean hull) and the auxiliaries of 10-12 knots, that limited the fleet speed to 9 knots.[34]

Additionally, there were significant deficiencies in the Russian naval fleet's equipment and training. Russian naval tests with their torpedoes exposed major technological failings.[q] Tōgō's greatest advantage was that of experience, having five of the ten fleet commanders in either navy with combat experience aboard modern warships on his side,[r] while Rozhestvensky had none. The others were all Russian admirals whom he had defeated, including Oskar Starck, who had been relieved of his command following his humiliating defeat in the Battle of Port Arthur; Admiral Stepan Makarov, killed by a mine off Port Arthur; Wilgelm Vitgeft, who had been killed in the Battle of the Yellow Sea; and Admiral (Prince) Pavel Ukhtomsky who was relieved and recalled to Mukden by Viceroy Yevgeni Alekseyev[s] after six battleships of the Pacific Squadron failed to reach Vladivostok as a result of Battle of the Yellow Sea.[36] Admiral Karl Jessen, who experienced Battle off Ulsan, remained in Vladivostok.

First contact[edit]

Departure of the Japanese Combined Fleet in the morning of 27 May 1905

Because the Russians wanted to slip undetected into Vladivostok, they approached Japanese waters in radio silence. They steered outside regular shipping channels to reduce the chance of detection. On the night of 26 May 1905 the Russian fleet approached the Tsushima Strait.[37]

In the night, thick fog blanketed the straits, giving the Russians an advantage. At 02:45 on 27 May Japan Standard Time (JST), the Japanese auxiliary cruiser Shinano Maru observed three lights on what appeared to be a vessel on the distant horizon and closed to investigate. These lights were from the Russian hospital ship Orel,[t] which, in compliance with the rules of war, had continued to burn them.[38] At 04:30, Shinano Maru approached the vessel, noting that she carried no guns and appeared to be an auxiliary. The Orel mistook the Shinano Maru for another Russian vessel and did not attempt to notify the fleet. Instead, she signaled to Shinano Maru in Russian code, which made no sense to the Japanese ship. The Shinano Maru then sighted the shapes of ten other Russian ships in the mist.

Wireless telegraphy played an important role from the start. At 04:55, Captain Narikawa of the Shinano Maru sent a message to the Combined Fleet command onboard Mikasa in Masampo that the "Enemy is in grid 203". By 05:00, intercepted radio signals informed the Russians that they had been discovered and that Japanese scouting cruisers were shadowing them. Admiral Tōgō received the message at 05:05, and immediately began to prepare his battle fleet for a sortie.[39]

Beginning of the battle[edit]

Routes of the Russian and Japanese fleets on 27–28 May 1905

At 06:34, before departing with the Combined Fleet, Admiral Tōgō wired a confident message to the navy minister in Tokyo:

In response to the report that enemy ships have been sighted, the Combined Fleet will immediately commence action and attempt to attack and destroy them. Weather today fine but high waves.[40]

The final sentence of this telegram has become famous in Japanese military history, and has been quoted by former Japanese Prime Minister Shinzō Abe.[41]

The entire Japanese fleet was put to sea, with Tōgō in his flagship Mikasa leading over 40 vessels to meet the Russians. Meanwhile, the shadowing Japanese scouting vessels sent wireless reports every few minutes as to the formation and course of the Russian fleet. There was mist which reduced visibility and the weather was poor. Wireless gave the Japanese an advantage; in his report on the battle, Admiral Tōgō noted the following:

Though a heavy fog covered the sea, making it impossible to observe anything at a distance of over five miles, [through wireless messaging] all the conditions of the enemy were as clear to us, who were 30 or 40 miles distant, as though they had been under our very eyes.[42]

At 13:40, both fleets sighted each other, ready to engage. At around 13:55, Tōgō ordered the hoisting of the Z flag, issuing a predetermined announcement to the entire fleet:

The Empire's fate depends on the result of this battle, let every man do his utmost duty.[43]

By 14:45, Tōgō had 'crossed the Russian T'[44] enabling him to fire broadsides, while the Russians could reply only with their forward turrets.[45][46]

Daylight action[edit]

Russian battleship Oslyabya, the first warship sunk in the battle

The Russians sailed from south-southwest to north-northeast; "continuing to a point of intersection which allowed only their bow guns to bear; enabling him [Tōgō] to throw most of the Russian batteries successively out of bearing."[47] The Japanese fleet steamed from northeast to southwest, then Tōgō ordered the fleet to turn 180-degrees in sequence, which enabled his ships to take the same course as the Russians. Although Tōgō's U-turn was successful, Russian gunnery had proven surprisingly good and the flagship Mikasa was hit 15 times in five minutes. Before the end of the engagement, she was struck 15 more times by large calibre shells.[48] Rozhestvensky had only two alternatives, "a charge direct, in line abreast", or to commence "a formal pitched battle."[47] He chose the latter, and at 14:08, the Japanese flagship Mikasa was hit at about 7,000 metres, with the Japanese replying at 6,400 meters. Superior Japanese gunnery then took its toll,[49] with most of the Russian battleships being crippled.

Captain 2nd Rank Vladimir Semenoff, a Russian staff officer aboard the flagship Knyaz Suvorov, said "It seemed impossible even to count the number of projectiles striking us. Shells seemed to be pouring upon us incessantly one after another. The steel plates and superstructure on the upper decks were torn to pieces, and the splinters caused many casualties. Iron ladders were crumpled up into rings, guns were literally hurled from their mountings. In addition to this, there was the unusually high temperature and liquid flame of the explosion, which seemed to spread over everything. I actually watched a steel plate catch fire from a burst."[50][51]

Ninety minutes into the battle, the first warship to be sunk was the Russian battleship Oslyabya from Rozhestvensky's 2nd Battleship division.[u] This was the first time a modern armoured warship had been sunk by gunfire alone.[53]

A direct hit on the Russian battleship Borodino's magazines by the Japanese battleship Fuji caused her to explode, which sent smoke thousands of metres into the air and trapped all but one[v] of her crew onboard as she sank.[50] Rozhestvensky was knocked out of action by a shell fragment that struck his skull. In the evening, Rear Admiral Nikolai Nebogatov took over command of the Russian fleet. The Russians lost the battleships Knyaz Suvorov, Oslyabya, Imperator Aleksandr III and Borodino. The Japanese ships suffered only light damage.

Night attacks[edit]

At night, around 20:00, 21 destroyers and 45 Japanese torpedo boats[w] were thrown against the Russians.[x] They were deployed initially from the North, East and West while being slightly visible, forcing the Russians, roughly in the order of cruisers, battleships and auxiliaries groups, to turn West.[55] The Japanese were aggressive, continuing their attacks for three hours without a break; as a result, during the night there were a number of collisions between the small craft and Russian warships.[y] The Russians were dispersed in small groups. By 23:00, it appeared that the Russians had vanished, but they revealed their positions to their pursuers by switching on their searchlights – ironically, the searchlights had been turned on to spot the attackers. The old battleship Navarin struck a chained floating mines[z] laid in front and was forced to stop in order not to push the chain forward, inviting other floating mines on the chain in on herself. She was consequently torpedoed four times and sunk. Out of a crew of 622, only three survived, one to be rescued by the Japanese and the other two by a British merchant ship.[56]

The battleship Sissoi Veliky was badly damaged by a torpedo in the stern and was scuttled the next day. Two old armoured cruisersAdmiral Nakhimov and Vladimir Monomakh – were badly damaged, the former by a torpedo hit to the bow, the latter by colliding with a Japanese destroyer. They were both scuttled by their crews the next morning off Tsushima Island, where they headed while taking on water.[57] The night attacks placed a great strain on the Russians, as they lost two battleships and two armoured cruisers, while the Japanese lost only three torpedo boats.[58]

XGE signal and Russian surrender[edit]

At 05:23 on 28 May, what remained of the Russian fleet was sighted heading northeast. Tōgō's battleships proceeded to surround Nebogatov's remaining squadron south of the island of Takeshima and commenced main battery fire at 12,000 meters.[59] The Russian cruiser Izumrud then turned South East and started to flee.[60] Realising that his guns were outranged by at least one thousand metres,[ab] and the Japanese battleships had proven on the day before to be faster than his own so that he could not close the distance if he tried, Nebogatov ordered the four battleships remaining under his command to surrender.[ac][ad] XGE, an international signal of surrender, was hoisted; however, the Japanese navy continued to fire as they did not have "surrender" in their code books and had to hastily find one that did.[61] Still under heavy fire, Nebogatov then ordered a white tablecloth sent up the masthead, but Tōgō, having faced the difficult decision to sink a British transport ship full of Chinese soldiers during the First Sino-Japanese War as the commander of IJN Cruiser Naniwa,[ae] knew the signal meant a request for a truce or parley, not 'surrender' in the legal definition, and that either meaning contradicted not stopping the ships.

His lieutenants found the codebook that included XGE signal and reported that stopping engines is a requirement for the signal and all the Russian ships were still moving, so he continued firing while the response flag signal "STOP" hoisted.[62] Nebogatov then ordered St. Andrew's Cross lowered and the Japanese national flag raised on the gaff and all engines stopped.[63] Seeing the requirement for the signal met, Tōgō gave the cease-fire and accepted Nebogatov's surrender. Nebogatov surrendered knowing that he could be shot for doing so.[50] He said to his men:

You are young, and it is you who will one day retrieve the honour and glory of the Russian Navy. The lives of the two thousand four hundred men in these ships are more important than mine.[50]

Damaged Oryol[t] at Maizuru Naval Arsenal[af]

As an example of the level of damage inflicted on a Russian battleship, Oryol[t] was hit by five 12-inch, nine 8-inch, 39 six-inch and 21 smaller or unidentified shells.[ag] This damage caused her to list, and the engine ceased to operate when she was being taken by the Japanese navy to First Battle Division home port of Sasebo in Nagasaki after Tōgō accepted the surrender. Cruiser Asama and then battleship Asahi had to tow Oryol, and their destination was changed to the closer Maizuru Naval Arsenal to avoid losing the prize of war. Her commander Captain Yung, who was seriously injured on 27 May, died in the night of the 29th onboard battleship Asahi en route.[ah][64]

Capture of Rozhestvensky[edit]

Captured Russian destroyer Byedoviy at Sasebo on 3 June 1905 [ai] before she became IJN Satsuki.

Russian destroyer Buyniy, after rescuing the squadron command including Admiral Rozhestvensky from the burning Knyaz Suvorov at 17:30 during the day battle on the 27th, found Cruiser Donskoi, destroyers Byedoviy and Grozniy in convoy on the morning of 28 May. Rozhestvensky chose Byedoviy to move the fleet command officers and himself as Buyniy had serious damages and Donskoi, being an old ship, was very slow. (Later in the afternoon, Buyniy was sunk by gunfire from Donskoi after taking the crew aboard.) Leaving the struggling Buyniy and the slow Donskoi[aj] behind, Byedoviy and Grozniy headed for Vladivostok.[66]

Japanese destroyers Sazanami and Kagerō had mechanical issues during the night battle on the 27th and had to fix the problems at the Port of Ulsan.[ak] Both destroyers finished their temporary repair work by the morning of the 28th and left the port together. They spotted the two Russian destroyers on the way to join the rest of the Combined Fleet and engaged at 15:25.[65][am]

Destroyer Grozniy increased speed being chased by Kagerō, but Byedoviy slowed down and stopped in the face of firing and approaching Sazanami while raising a white flag.[69][an] Grozniy was able to keep sufficient distance from Kagerō, exchanging just a few long-distance shots at about 18:30, before nightfall.[70] She became one of the three warships reaching Vladivostok after surviving the battle.

The Combined Fleet command could not believe the news when Cruiser Akashi, which rendezvoused Sazanami on the morning of the next day, sent a radio telegraph message about the capture of Admiral Rozhestvensky, as they were certain to have sunk Knyaz Suvorov and assumed the squadron commander went down with the flagship.[68] But cruiser Akashi, accompanied by Sazanami and Kagerō, arrived at Sasebo port in the morning of 30 May with Byedoviy in tow, with not only the injured admiral but also the surviving members of the Russian fleet command onboard.[ao][68][65]

Tsar Nicholas II, who was executed on 17 July 1918 and the remains found near Yekaterinburg in 1979, was interred in the white cathedral shown behind in 1998.[71] Russian cruiser Aurora is displayed 1km away[aq] from this fortress.

Until the evening of 28 May, isolated Russian ships were pursued by the Japanese until almost all were destroyed or captured. The cruiser Izumrud, which escaped from the Japanese despite being present at Nebogatov's surrender, was destroyed by her crew after running aground on the Siberian coast.[72]

The wounded Admiral Rozhestvensky went to the Imperial Japanese Naval Hospital in Sasebo to recover from a head injury caused by shrapnel; there, the victorious Admiral Tōgō visited him personally in plain clothes, comforting him with kind words: "Defeat is a common fate of a soldier. There is nothing to be ashamed of in it. The great point is whether we have performed our duty."[75]

On 10 June 1905, Tsar Nicholas II sent a telegram :

“Tokyo. Adjutant General Rozhdestvensky. From the bottom of my heart I thank you and all the ranks of the squadron who honestly fulfilled their duty in battle, for their selfless service to Russia. Your feat was destined to be crowned with success, but your fatherland will always be proud of your selfless courage. I wish you a speedy recovery, and may God console you all.  Nikolai"[76]

Rozhestvensky and other officers were placed on trial in August 1905 after returning to Russia. Rozhestvensky claimed full responsibility for the fiasco and was sentenced to death, but the Tsar commuted his death sentence. Flag captains Clapier de Colongue (Second Pacific Squadron) and Cross (Third Pacific Squadron), Staff officers Filippinovsky, Leontieff, together with the commanders of the surrendered battleships, Captains Vladimir Smirnov (Nikolai I), Nikolai Lishin[as] (Apraksin), Sergei Grogoryev (Senyavin),[77] and the Byedoviy commander Nikolai Baranov were sentenced to 10 years in prison and dismissed from service (Nicholas II pardoned them on 1 May 1909).[78] The executive officer of Oryol (who was in charge of the ship at the surrender) Captain 2nd rank K.L.Schwede and other officers were acquitted.[76]

Admiral Nebogatov, who surrendered the fleet, was also sentenced to death, which was commuted to 10 years imprisonment and eventually pardoned by the Tsar. He was released from the Trubetskoy Bastion prison in Peter and Paul Fortress in May 1909.

Contributing factors[edit]

Commander and crew experience[edit]

Admiral Rozhestvensky faced a more combat-experienced battleship admiral in Tōgō Heihachirō. Admiral Tōgō had already killed two Russian admirals: Stepan Makarov outside of Port Arthur in the battleship Petropavlovsk in April 1904, then Wilgelm Vitgeft in his battleship Tsesarevich in August of the same year. Before those two deaths, Tōgō had chased Admiral Oskar Starck, also flying his flag in the Petropavlovsk, off the battlefield. Admiral Tōgō and his men had two battleship fleet action experiences, which amounted to over four hours of combat experience in battleship-to-battleship combat at Port Arthur and the Yellow Sea.[79] The Japanese fleets had practiced gunnery extensively since the beginning of the war, using sub-calibre practice guns[at] mounted in their larger guns.[au][av][aw]

In contrast, Russian battleship Borodino underwent sea trials from 23 August to 13 September 1904[63] as a brand new ship upon her completion,[82] and the new crew did not have much time for training before she set sail for the Pacific on 15 October 1904. Borodino's sister ship, Knyaz Suvorov started trials on 9 August, Oryol[t] started trials the latest on 10 September 1904, leaving Imperator Aleksandr III (the trials finished in October 1903) as the only Borodino-class ship actually ready for deployment.[63][ax] As the Imperial Russian Navy planned on building 10 Borodino-class battleships (5 were ultimately built) with the requirement for thousands of additional crewmen, the basic training, quality and experience of the crew and cadets were far lower[83] than those onboard the battleships in the seasoned Pacific Fleet.[84]

The Imperial Russian Admiralty Council (Адмиралтейств-совет) and the rest of the Admiralty were quite aware of this disadvantage, and opposed the September dispatch plan[ay] for the following reasons:

1. The Japanese navy has completed the battle preparations with all the crew having some combat experience.

2. The long voyage is mostly through extreme tropical weather, so a meaningful training is practically impossible on the way.

3. Therefore, the newly created Second Pacific Fleet should conduct training in the Baltic until the next spring while waiting for the rigging of another battleship, Slava,[az] and the purchase of Chilean and Argentine warships.[ba][63]

However, at the council in the imperial presence on 23 August 1904 held at the Peterhof Grand Palace, this opinion was overruled by Admiral Rozhestvensky (Commander in Chief of the Fleet), Navy Minister Avellan, and Tsar Nicholas II; for it was deemed impossible to re-arrange the massive coaling for the long voyage if the navy broke the contract that was already signed with Hamburg-American Steamship Line of Germany.[63]

Salvo firing director system[edit]

Up to the Battle of the Yellow Sea on 10 August 1904, naval guns were controlled locally by a gunnery officer assigned to that gun or a turret. He specified the elevation and deflection figures, gave the firing order while keeping his eyes on the inclinometers indicating the rolling and pitching angles of the ship, received the fall of shot observation report from the spotter on the mast, calculated the new elevation and deflection to 'walk' the shots in on the target for the next round, without much means to discern or measure the movements of his own ship and the target. He typically had a view on the horizon, but with the new 12-inch gun's range extended to over 8 miles (13 km), his vantage point was lower than desired.[86][bb]

In the months before the battle, the Chief Gunnery Officer of Asahi, Lieutenant Commander Katō Hiroharu, aided by a Royal Navy advisor who introduced him to the use of the early mechanical computer Dumaresq in fire control, introduced a system for centrally issuing the gun-laying[bc] and salvo-firing orders by voice.[bd] Using a central system allowed the spotter to identify a salvo of distant shell splashes much more effectively than trying to identify a single splash among the many in the confusion of fleet-to-fleet combat. Further, the spotter needed to keep track of just one firing at a time as opposed to multiple shots on multiple stopwatches, in addition to having to report to just one officer on the bridge. The 'director' officer on the bridge had the advantage of having a higher vantage point than in the gun turrets, in addition to being steps away from the ship commander giving orders to change the course and the speed in response to the incoming reports on target movements.[89]

This fire control director system was introduced to other ships in the fleet, and the training and practice on this system were carried out in the months waiting for the arrival of the Baltic Fleet[av][au] while its progress was reported by the British intelligence from their naval stations at Gibraltar, Malta, Aden (Yemen), Cape of Good Hope, Trincomalee (Ceylon), Singapore and Hong Kong, among other locations.[90]

As a result, Japanese fire was more accurate in the far range (3 to 8 miles or 5 to 13 kilometres),[be] on top of the advantage they held in the shorter distances using the latest 1903 issue Barr and Stroud FA3 coincidence rangefinders of baselength 5 ft (1.5 m),[bf] which had a range of 6,000 yards (5,500 m), while the Russian battleships were equipped with Liuzhol stadiametric rangefinders from the 1880s (except battleships Oslyabya and Navarin, which had the Barr and Stroud 1895 issue FA2 of baselength 4.5 ft (1.4 m) retrofitted), which only had a range of about 4,400 yards (4,000 m).[92]

Wireless telegraphy[edit]

The wireless telegraph (radio) had been invented during the last half of the 1890s, and by the turn of the century, nearly all major navies were adopting this improved communications technology. Tsushima was "the first major sea battle in which wireless played any role whatsoever".[93][94]

Lieutenant Akiyama Saneyuki (who was the key staff to Admiral Tōgō in formulating plans and directives before and during the battle as a Commander, who also went aboard Nikolai I to accompany Admiral Nebogatov to Mikasa for a formal meeting with Tōgō) had been sent to the United States as a naval attaché in 1897. He witnessed the capabilities of wireless telegraphy firsthand during the Spanish–American War, and sent several memos to the Navy General Staff urging that they push ahead as rapidly as possible to acquire the new technology.[94] The IJN command became heavily interested in the technology; however, it found the Marconi wireless system, which was then operating with the Royal Navy, to be exceedingly expensive.

Kimura Shunkichi (in plain clothes on the front row) and the members of Imperial Japanese Navy Wireless Telegraph Research Committee in 1900.

The Japanese therefore decided to create their own radio sets by setting up a wireless research committee under Professor Kimura Shunkichi,[bg] which eventually produced an acceptable system. In 1901, having attained radio transmissions of up to 60 miles (97 km) with the Type 34 (34th year of Meiji = 1901) set, the Navy formally adopted wireless telegraphy. Two years later, a laboratory, a factory, and the wireless telegraphy curriculum were set up at Imperial Japanese Navy Mines Training School in Yokosuka to produce the Type 36 (1903) wireless sets,[bh] and these were quickly installed on every major warship in the Combined Fleet by the time the war started.[94]

Alexander Stepanovich Popov of the Naval Warfare Institute had built and demonstrated a wireless telegraphy set in 1900. However, technology improvement and production in the Russian empire lagged those of Germany, and "System Slaby-Arco",[bi][95] originally made by Allgemeine Elektricitäts-Gesellschaft (AEG) and then produced in volume by its successor wireless-set maker Telefunken in Germany (by 1904, this system was in wide use by Kaiserliche Marine) was adopted by the Imperial Russian Navy. Although both sides had early wireless telegraphy, the Russians were using German sets tuned and maintained by German technicians half-way into the voyage,[96] while the Japanese had the advantage of using their own equipment maintained and operated by their own navy specialists trained at the Yokosuka school.[bj]

British support[edit]

Illustration by E.Huskinson for the Conservative Party c. 1905–1910.

The United Kingdom assisted Japan by manufacturing guns[bk] and building battleships for the IJN.[97] As the ally in the Anglo-Japanese Alliance, the UK also assisted Japan in intelligence, finance, technology, training and other aspects of the war against Russia. At the time, Britain owned and controlled more harbour facilities around the world – specifically shipyards and coaling stations – than Russia and its allies (France,[bl] and to some extent Germany) combined. The UK also obstructed, where possible, Russian attempts to purchase ships and coal.[90] France openly allowed the Baltic Fleet warships into Tangier port before and after the Dogger Bank Incident; and the UK formally protested in the post-Dogger Bank negotiations, pointing out that the 'Neutral' countries cannot accept warships of the fighting countries into their ports without enforcing internment,[bm] and if France is no longer neutral in the war, the UK is obligated to commence military action in support of Japan as required in the Anglo-Japanese Alliance.[bn] As a result, the rendezvous point for Rozestvensky and Fölkersahm squadrons was changed from the port of Diego Suarez to the remote islands of Île Sainte-Marie and Nosy Be in Madagascar, and free access to the ports including Saigon and Ba Ngoi port in Cam Ranh Bay was denied for the fleet in French Indochina.[bo]

This support created a major logistics problem for around the world deployment of the Baltic Fleet to the Pacific in procuring coal and supplies on the way.[101][102] At Nosy Be in Madagascar and at Camranh Bay, French Indochina, the fleet was forced to be anchored for about two months each, seriously degrading morale of the crew. By the time it reached the Sea of Japan, the hulls of all the ships in the fleet were heavily fouled in addition to carrying the extra coal otherwise not required on deck.[103][o]

The Japanese ships, on the other hand, were well maintained in the ample time given by the intelligence. For example, battleship Asahi was under repair from November 1904 to April 1905 at Sasebo Naval Arsenal for two 12-inch guns lost and serious damage to the hull from striking a mine. They were divided into battle divisions of as much uniform speed and gun range so that a fleet would not suffer a bottleneck in speed, and the range of guns would not render some ships useless within a group in extended-range combat.[104][d]

At the end of the Argentine-Chilean naval arms race in 1903, two Chilean-ordered and British-built battleships (then called Constitución and Libertad) and two Argentine-ordered, Italian-built cruisers (then called Bernardino Rivadavia and Mariano Moreno) were offered to Russia and the purchase was about to be finalized.[105] Britain stepped in as the mediator of Pacts of May that ended the race, bought the Chilean battleships (which became HMS Swiftsure and HMS Triumph), and brokered the sale of Argentine cruisers to Japan.[bp] This support not only limited the growth of the Imperial Russian Navy but also helped IJN in obtaining the Italian-built cruisers (IJN Kasuga and Nisshin) with a strong armour design [bq] that enabled IJN to use them on the main line of battle along with the heavier-armoured battleships.[108][br]

High explosive and cordite[edit]

The Japanese used mostly high-explosive shells filled with Shimose powder, which was a pure picric acid (as opposed to the French Melinite or the British Lyddite, which were picric acid mixed with collodion (French) or with dinitrobenzene and vaseline (British) for stability).[109] Engineer Shimose Masachika (1860–1911) solved the instability problem of picric acid on contact with iron and other heavy metals by coating the inside of a shell with unpigmented Japanese lacquer and further sealing with wax.[110] Because it was undiluted, Shimose powder had a stronger power in terms of detonation velocity and temperature than other high explosives at the time.[109] These shells had a sensitive Ijuin fuse[111] (named after Vice Admiral Ijuin Gorō[bs]) at the base as opposed to the tip of a shell that armed itself when the shell was spun by the rifling. These fuses were designed to explode on contact and wreck the upper structure of ships.[bt][114] The Japanese Navy imported Cordite from Great Britain as the smokeless propellant for these Shimose shells,[109] so that the smoke off the muzzle would not impede the visibility for the spotters.

In the early 1890s, Vice Admiral Stepan O. Makarov, then the Chief Inspector of Russian naval artillery, proposed a new 12-inch gun design, and assigned a junior officer, Semyon V. Panpushko, to research the use of picric acid as the explosive in the shell. However, Panpushko was blown into pieces in an accidental explosion in experiment due to the instability.[bu] Consequently, high explosive shells remained unreachable for the Russian Navy at the time of the Russo-Japanese War, and the navy continued to use the older armour-piercing rounds with guncotton (Nitrocellulose, Pyroxylin) bursting charges and the insensitive delayed-detonation fuses. They mostly used brown powder or black powder as the propellant, except Sissoi Veliky and the four Borodino-class ships that used smokeless gunpowder for the main 12-inch guns.[115]

As a result, Japanese hits caused more damage to Russian ships than Russian hits on Japanese ships. Shimose blasts often set the superstructure, the paintwork and the large quantities of coal stored on the decks on fire,[101] and the sight of the spotters on Russian ships was hindered by the large amount of smoke generated by the propellant on each uncoordinated firing.[bv] Moreover, the sensitivity difference of the fuse caused the Japanese off-the-target shells to explode upon falling on the water creating a much larger splash that sent destabilizing waves to Russian inclinometers,[bw][bx] as opposed to the Russian shells not detonating upon falling on the water.[by] This made an additional difference in the aforementioned shot accuracy by aiding the Japanese spotters to make an easier identification in fall of shot observation.

Gun range and rate of fire[edit]

The Makarov proposal resulted in Model 1895 12-inch gun that extended the range of the previous Model 1886 12-inch Krupp guns (installed on Imperator Nikolai I and Navarin) from 5–6 km to 11 km (at 15-degrees elevation) at the expense of significantly limited amount of explosives that can be contained in the 332 kg (732 lb) shell.[118][bz] Reload time was also improved from 2–4 minutes previously to a rated 90 seconds, but in reality, it was 2.5–3 minutes.[121] These guns were installed to Sissoi Veliky and the four Borodino-class ships.[115]

The four Japanese battleships, Mikasa, Shikishima, Fuji and Asahi, had the latest Armstrong 12-inch 40-calibre naval gun designed and manufactured by Sir W.G. Armstrong & Company ahead of its acceptance by the Royal Navy in the UK. These British-built 12-inch guns had a range of 15,000 yards (14 km) at 15-degrees elevation and the rate of fire at 60 seconds with a heavier 850 lb (390 kg) shell.[ca] One of the reasons for the Royal Navy's late adoption of this type of gun was the accidental shell explosions in the barrel Japanese battleships experienced up to the Battle of the Yellow Sea in August 1904, which were diagnosed and almost rectified[cb] by the Japanese Navy with the use of aforementioned Ijuin Fuse[111] by the time of this battle.

The Russian fleet had 20 of the 1895-issue longer range 12" guns on five battleships compared to 16 of the Armstrong 12" guns on four battleships for the Japanese. Statistically, this 20% advantage in the number of guns was much more than offset by the 60% disadvantage in the rate of fire difference of one shot in 2.5 minutes versus one minute. The range difference of 11 km versus 14 km translated into a flatter trajectory (smaller elevation and fall angle) for the Japanese shells, which resulted in a better hit rate for the Japanese shots[cc] when both sides had an equal distance facing each other in 11 km and shorter range.[ce]

Russian losses[edit]

Russian personnel losses were 216 officers and 4,614 men killed; with 278 officers and 5,629 men taken as Prisoners Of War (POW). Interned in neutral ports were 79 officers and 1,783 men. Escaping to Vladivostok and Diego-Suarez were 62 officers and 1,165 men.[162]

The battle was humiliating for Russia, which lost all its battleships and most of its cruisers and destroyers. The battle effectively ended the Russo-Japanese War in Japan's favour. The Russians lost 4,380 killed and 5,917 captured with a further 1,862 interned.[75] Two admirals, Rozhestvensky and Nebogatov, were captured by the Japanese Navy. The second in command of the fleet, Rear Admiral Dmitry Gustavovich von Fölkersahm, after suffering a cerebral hemorrhage on 16 April, died in the night of 24 May 1905 onboard battleship Oslyabya.[63] Vice Admiral Oskar Enqvist fled to Manila onboard cruiser Oleg and was interned by the United States.


The Russians lost eleven battleships, including three smaller coastal battleships, either sunk or captured by the Japanese, or scuttled by their crews to prevent capture. Four were lost to enemy action during the daylight battle on 27 May: Knyaz Suvorov, Imperator Aleksandr III, Borodino and Oslyabya. Navarin was lost during the night action on 27–28 May, while the Sissoi Veliky and Admiral Ushakov[163] were either scuttled or sunk the next day. Four other battleships, under Rear Admiral Nebogatov, were forced to surrender and would end up as prizes of war. This group consisted of only one modern battleship, Oryol, along with the old battleship Imperator Nikolai I and two small coastal battleships General-Admiral Apraksin and Admiral Seniavin.[163]


The Russian Navy lost five of its nine cruisers during the battle, three more were interned by the Americans, with just one reaching Vladivostok. Vladimir Monomakh and Svetlana were sunk the next day after the daylight battle. The cruiser Dmitrii Donskoi fought against six Japanese cruisers on the 28th and barely survived with many officers and crew killed onboard, and was scuttled on 29 May 1905 due to heavy damage. Izumrud ran aground on the Siberian coast.[163] Three Russian protected cruisers, Aurora, Zhemchug, and Oleg, escaped to the U.S. naval base at Manila[163] in the then-American-controlled Philippines where they were interned by the United States. The armed yacht (classified as a cruiser) Almaz, alone was able to reach Vladivostok.[178]

Destroyers and auxiliaries[edit]

Imperial Russia also lost six of its nine destroyers in the battle, had one interned by the Chinese, and the other two reached Vladivostok. Buyniy ("Буйный"), Bezuprechniy ("Безупречный"), Gromkiy ("Громкий") and Blestyashchiy ("Блестящий") were sunk on 27 May. Bistriy ("Быстрый") was beached and destroyed by her crew the next day. Byedoviy ("Бедовый") surrendered also on 28 May. Destroyer Bodriy ("Бодрый")[co] ran out of coal, and was interned in Shanghai.[164] Grozniy ("Грозный") and Braviy ("Бравый") reached Vladivostok.[179]

Of the auxiliaries, repair ship Kamchatka, auxiliary cruiser Ural and ocean tug Rus were sunk on 27 May, auxiliary cruiser Irtysh was disabled, abandoned on 28 May, then sank on 29 May. Ammunition ship Koreya and ocean tug Svir reached Shanghai and returned home. After being ordered to separate from the fleet on 22 May,[p] auxiliary cruisers Kuban and Terek were interned at Batavia in Dutch East Indies by the Netherlands on 9 June 1905 after raiding a British and a Danish steamer destined for Japan. Transports Yaroslavl, Vladimir, Kuronia, Voronezh, Livonia and Meteor were detached from the fleet on 25 May, reached Shanghai and returned home. Auxiliary cruisers Rion and Dniepr[165] escorted the transports to Shanghai, engaged in commerce raiding activities in the Yellow Sea, and returned to Kronstadt on 31 July 1905.[180] Transports Mercury, Tambov, Herman Lerke, Count Stroganov and repair ship Ksenia, which accompanied the Third Pacific Fleet to Cam Ranh Bay, had been sent home via Saigon.[30] Merchant cruiser Anadyr escaped to Madagascar and then returned home. The hospital ships Orel and Kostroma were captured during the battle; Kostroma was released afterwards.[cy]

Japanese losses[edit]

The Japanese lost three torpedo boats (Nos. 34, 35 and 69). Personnel losses were 117 officers and men killed and 583 officers and men wounded.[162][75]

Political consequences[edit]

Imperial Russia's prestige was badly damaged and the defeat was a blow to the Romanov dynasty. Most of the Russian fleet was lost; the fast armed yacht Almaz (classified as a cruiser of the 2nd rank) and the destroyers Grozny and Bravy were the only Russian ships to reach Vladivostok.[178] In The Guns of August, the American historian and author Barbara Tuchman argued that because Russia's loss destabilized the balance of power in Europe, it emboldened the Central Powers and contributed to their decision to go to war in 1914.[181]

The battle had a profound cultural and political impact on the world. It was the first defeat of a European power by an Asian nation in the modern era.[182][183] It also heightened the alarm of "The Yellow Peril" as well as weakening the notion of white superiority that was prevalent in some Western countries.[184][185] Mahatma Gandhi (India), Mustafa Kemal Atatürk (Turkey), Sun Yat-sen (China) and Jawaharlal Nehru (India) were amongst the future national leaders to celebrate this defeat of a colonial power.[186] The victory established Japan as the sixth greatest naval power[187] while the Russian navy declined to one barely stronger than that of Austria-Hungary.[187]

In The Guinness Book of Decisive Battles, the British historian Geoffrey Regan argues that the victory bolstered Japan's increasingly aggressive political and military establishment. According to Regan, the lopsided Japanese victory at Tsushima:

...created a legend that was to haunt Japan's leaders for forty years. A British admiral once said, 'It takes three years to build a ship, but 300 years to build a tradition.' Japan thought that the victory had completed this task in a matter of a few years ... It had all been too easy. Looking at Tōgō's victory over one of the world's great powers convinced some Japanese military men that with more ships, and bigger and better ones, similar victories could be won throughout the Pacific. Perhaps no power could resist the Japanese navy, not even Britain and the United States.[75]

Regan also believes the victory contributed to the Japanese road to later disaster, "because the result was so misleading. Certainly the Japanese navy had performed well, but its opponents had been weak, and it was not invincible... Tōgō's victory [helped] set Japan on a path that would eventually lead her" to the Second World War.[75]

Takano Isoroku, the future Japanese admiral Yamamoto Isoroku who would plan the attack on Pearl Harbor and command the Imperial Japanese Navy through much of the Second World War, served as a junior officer (aboard Nisshin) during the battle and was wounded and lost two fingers by an accidental explosion of an 8-inch shell in a forward gun. Had he lost a third, he would have been medically discharged from the IJN.[188]

Dreadnought arms race[edit]

Prior to the Russo-Japanese War, countries constructed their battleships with mixed batteries of mainly 6-inch (152 mm), 8-inch (203 mm), 10-inch (254 mm) and 12-inch (305 mm) guns, with the intent that these battleships fight on the battle line in a close-quarter, decisive fleet action. The Battle of Tsushima conclusively demonstrated that faster battleships and big guns[189] with longer ranges were superior to batteries of mixed-size guns.[190]

Japanese battleship Satsuma, laid down on 15 May 1905, earlier than HMS Dreadnought (1906), was designed with 12 x 12" 40 Cal. guns.
(She ended up with 4 x 12" 45 Cal. Armstrong plus 12 x 10" 45 Cal. Vickers guns and became the largest battleship in the world at launch in 1906.)

Britain's First Sea Lord, Admiral Jackie Fisher, reasoned that the Japanese victory at Tsushima confirmed the importance of large guns and speed for modern battleships.[191][192] While Captain William Pakenham of the British Royal Navy, who had been present aboard the Japanese battleship Asahi as an official observer during the Tsushima Battle, "famously remarked...the effect of the fire of every gun is so much less than that of the next larger size, that when 12in guns are firing, shots from 10in pass unnoticed...everything in this war has tended to emphasize the vast importance to a ship, at every stage of her career, of carrying some of the heaviest and furthest shooting guns that can be got into her."[193] In October 1905 the British started the construction of HMS Dreadnought, which marked the beginning of a naval arms race between Britain and Germany in the years before 1914.[194]

The battle also accelerated the naval arms race on a geopolitical level; though the Anglo-German naval arms race had begun in 1897, the collapse of Russian naval power in 1905 allowed Britain to send the bulk of its naval forces to other regions, reassured by the naval superiority of its ally Japan in the Far East. In turn, the presence of a larger British fleet in Europe meant that the Germans must build a proportionally larger fleet to maintain the same relative power, in accordance with Tirpitz's fleet in being principle. The Royal Navy, in turn, must increase its fleet size to maintain the relative power as set out by its two-power standard. This positive feedback meant that any external increase in the regional naval power of one side – in this case, the British – would precipitate not just a proportional increase in naval power from the opposing side, but rather a mutual multi-stage build-up in naval power on both sides, before settling to a higher equilibrium. Ultimately, the Germans passed three of its five Fleet Acts after Tsushima within a span of 6 years.[195]

Upon the breakout of World War I, the British and Germans were both aware of the potentially devastating consequences of a naval defeat on the scale of Tsushima. Britain needed its battle fleet to protect its empire, and the trade routes vital to its war effort. Winston Churchill, then First Lord of the Admiralty, described British Admiral John Jellicoe as "the only man who on either side could lose the war in an afternoon."[196] German naval commanders, for their part, understood the importance Kaiser Wilhelm II attached to his navy and the diplomatic prestige it carried. As a result of caution, the British and German fleets met in only one major action in World War I, the indecisive Battle of Jutland.[197]

On film[edit]

The battle has been the main focus for two historical films in Japan. The first, 1969's Battle of the Japan Sea (日本海大海戦, Nihonkai Daikaisen), directed by Seiji Maruyama, starring Toshiro Mifune as Admiral Tōgō, with music by Masaru Sato and special effects by Eiji Tsuburaya. It was dramatized again in 1983's Battle Anthem (日本海大海戦・海ゆかば, Nihonkai Daikaisen – Umi Yukaba) with Mifune reprising his role.

Another, more recent, depiction is episode 4, season 3 of the 2009–2011 NHK taiga drama series Saka no Ue no Kumo (坂の上の雲) (lit. "Clouds Above the Slope").

  23. ^ 21 destroyers and 31 torpedo boats of the Combined Fleet, 4 torpedo boats from Kure Naval District, and 10 torpedo boats from Takeshiki Guard District.[d]
  24. ^ After the war, Admiral Rozhestvensky was asked in a Russian court martial why he chose day time to pass the most dangerous zone of Tsushima Strait. His answer was "Because torpedo boats in the night is a greater risk for battleships."
  25. ^ a b Lighthouses at the North-end ("Mitsushima Lighthouse" (in Japanese).) and the South-end ("Kousaki Lighthouse" (in Japanese).) of Tsushima were lit to indicate the borders of the area on the East side of Tsushima Island in which destroyers and torpedo boats are ordered to be free to attack any larger-than-destroyer ship in the dark.
  26. ^ a b The composition of Shimose Powder, director-controlled salvo firing, the use of Ijuin Fuse and the shells not being armour-penetrating/delayed-detonation, and this chained floating mines on the Japanese side, and Makarov Tip, the death of Rear Admiral von Fölkersahm, which strait the fleet was headed going into the Sea of Japan, and the use of Barr and Stroud rangefinders by Oslyabya and Navarin on the Russian side were top secrets at the time. Most of the official records were not kept on these items.
  27. ^ See Russian battleship Oryol#Construction and career
  28. ^ Oryol had lost its front left main gun, and the rear left gun could no longer be raised to extended-range elevations,[aa] meaning that only four 12-inch guns were left in the fleet: two older black-powder firing (shorter range) guns on Imperator Nikolai I, and two longer-range guns on the damaged Oryol that had however lost both of its rangefinders.
  29. ^ During Nebogatov's court martial, his defense for surrendering his battle fleet was because his guns were outranged by the Japanese guns.
  30. ^ In retrospect, the Japanese main 12" guns outranged his shorter-range 12" Krupp guns by 8000 metres and the longer-range 1895-issue 12" guns by about 3000 metres. See the Gun range and rate of fire section for details. The Japanese fleet had 14 (out of 16) of the 12" Armstrong guns operational on the four main battleships at the time.
  31. ^ See Battle of Pungdo#Kowshing Incident for details of this incident on 25 July 1894. He had suffered pneumonia and was taken off duty for 3 years from 1887 before the Sino-Japanese war. He utilised the time to research and became an expert in international law. Japan had just signed the Anglo-Japanese Treaty of Commerce and Navigation with the UK on 16 July 1894, and his decision to sink the British ship (flying the British civilian ensign) after a boarding inspection, maritime capture, and demanding to abandon ship, was later cleared by British jurists to be in compliance with Admiralty law. He also experienced Chinese cruiser Jiyuan fleeing from the Battle of Pungdo after raising a white flag and the Japanese naval ensign.

  33. ^ See Russian battleship Oryol#Construction and career for details. Due to her position in the Russian formation being the last in line of four Borodino-class battleships, Oryol probably received the least number of large calibre shells and possibly the most number of small calibre hits among the four.
  34. ^ a b Oryol's officers and most of the crew were taken aboard battleship Asahi, which towed and then accompanied Oryol, after her engines were temporarily repaired, to Maizuru. The Burial at sea was conducted for Captain Nikolay Viktorovich Yung at 07:30 on 30 May 1905 onboard Asahi, all hands on fore-deck with all Russians and Japanese lined up. Half-mast was flown on battleships Asahi, Oryol and cruiser Asama.[131] After the funeral, a piece of cardboard with "35°56'13"North, 135°10'East" written on, was given by a Japanese officer to the junior navigator, Lieutenant Leonid Larionov who was personally close to the captain from his childhood.[77]

He spent 350 Yen (equivalent to one year's Lieutenant salary) of personal funds to purchase the same model, and the binoculars had reached him stationed at Tsushima from the agent in Tōkyō before this battle.[68]
  40. ^ According to Novikov-Priboy,[65] Byedoviy raised a white table cloth on the foremast, Red Cross flag on the rear mast, and had lowered the Saint Andrew's Cross from the stern flag pole, by the instruction of the Flag Captain Clapier de Colongue (the most senior officer onboard the destroyer after the injured admiral, outranking the ship commander Captain 2nd rank Nikolai Baranov.), who reasoned Byedoviy had become a hospital ship.

  46. ^ Large calibre long barrel rifle with special mounts to be centered in the bore
  47. ^ a b During the 11 days from 28 March to 7 April 1905, Mikasa had 5 days with gunnery training sessions. In these 5 days, Mikasa fired 9,066 rounds of practice ammunition.
  48. ^ a b As an indication of unusually high level of gunnery training Tōgō applied to the fleet, the Maizuru Naval Arsenal requested an increase in 1905 fiscal year budget for additional 40,000 rounds of sub-calibre practice ammunition on 17 May 1905 for Mikasa, 34,000 rounds for cruiser Nisshin, 1,000 rounds per gun for destroyer Sazanami, among others, as they depleted annual allocations merely one and a half months into the fiscal year (Fiscal years begin on 1 April). These requests were all approved by the Fleet Management Dept. of the Naval Ministry for the entire fleet.[80]
  49. ^ The Russian 2nd Pacific Squadron departed Libau with small supply of sub-calibre practice ammunition. The transport Irtysh was loaded with additional practice ammunition for the squadron, but was delayed in departure due to an accident, and was left behind at Libau for repair. The Russian Admiralty decided to unload the ammunition, send it via the Trans-Siberian railroad to Vladivostok, and reload the ship with coal, without notifying Rozhestvensky (who was promoted to rear admiral on the strength of founding the gunnery training school of the Baltic Fleet.[65]), who learned about the decision after reaching Madagascar. The squadron conducted four practice sessions each at Nosy Be and Cam Ranh Bay.[81]

  54. ^ Approximate distance to horizon is calculated by sqrt(2 x h x R) where R is the Earth radius and h is the observation height above the sealevel. (see horizon for details.) Using battleship Mikasa as the example, the height of gunsight on top of 12" main gun turret (technically they are barbettes with armoured covers that make them look like turrets) is about 10 to 11m from the waterline and the bridge height is about 16 to 18m from the waterline by estimating from the sideview plan. Using the globally-averaged earth radius of 6,371,000m[87] for the R, the distance observable from the turret is sqrt(2 x 11 x 6371000m) = 11.8km. The distance observable from the bridge is sqrt(2 x 16 x 6371000m) = 14.3km. Mikasa's main guns had a range of 14km. (This explanatory note is provided for the benefit of the readers in accordance with WP:CALC.)
  55. ^ What ship to target, and the distance to the target were specified on the bridge. Each gun/turret aimed the target to determine the deflection, and used a distance-to-elevation conversion table for the gun to set the elevation.
  56. ^ All the gunnery personnel on Mikasa was given a lecture on telephone systems at 17:20 on 18 April 1905 in Chinhae Bay.[88]
  57. ^ On 6-7 April 1905, Mikasa conducted the second sub-calibre gunnery training competition against Shikishima. Mikasa scored 285 hits / 927 shots (30.7%), Shikishima scored 258/974 (26.5% hitrate) on opposite course; Mikasa scored 894/1703 (52.5%), Shikishima scored 1085/1672 (64.9%) on the same course with the target at the distance of 280–720 m at 6 knots, with towed target by torpedo-boat at 6 knots.[91]
  58. ^ Baselength is the distance between the left and the right lens or mirror facing the target, which largely determines the effective range of a rangefinder.

  63. ^ IJN almost exclusively used Armstrong guns on its heavier ships of the time. Cruisers Chitose and Kasagi were built in the US, but their main guns were Armstrong. Cruisers Kasuga and Nisshin were built in Italy with Armstrong guns (Sir W.G. Armstrong & Company had a factory, Stabilimenti meccanici di Pozzuoli, in Italy). IJN licensed the design of Armstrong 8" guns and had started producing it in 1902.
  64. ^ See Franco-Russian Alliance for details.
  65. ^ The time was in between Hague Conventions of 1899 and 1907, and international agreements were not formalised on naval warfare yet (except on hospital ships). This argument made by Great Britain, based on Section IV "On the Internment of belligerents and the care of the wounded in neutral countries," (Article 57) of the 1899 agreement (which says "A neutral State which receives in its territory troops belonging to the belligerent armies shall intern them"[98]), may have been acceptable to most governments in the world at the time. However, as it was incorporated into the 1907 Convention, it said "Belligerents are forbidden to use neutral ports and waters as a base of naval operations against their adversaries (Article 5)" with further articles permitting up to 24-hour stay (Article 12) for the maximum of three warships of a belligerent at war in any neutral port (Article 15) if the neutral power permitted.[99]
  66. ^ The alliance required both countries to join the war if one of them faces "more than one" countries as the adversary. The Franco-Russian Alliance had a similar requirement, but in wars against Germany only. The French government had to accept the logic, as France did not wish to risk going into war against the UK, nor wish to give any excuse for the Royal Navy to attack the Russian warships with or without declaring war.
  67. ^ When the Rozestvensky squadron reached Dakar after leaving Tangier, the ships were allowed into the port and carry out coaling, but upon exchanges of telegram messages with Paris by the local authorities, they were banned from the port.[100] The German government, who had interned Russian battleship Tsesarevich at Qingdao on 11 August 1904, took a lenient stance towards the squadron as a neutral power in the war. After the Dakar stop, the Rozestvensky squadron reached Angra Pequena Bay in German South West Africa on 15 November 1904 (Gregorian), and the local Lüderitz authorities, busy in the Herero and Namaqua genocide, did not object to the mooring and coaling in the port until their departure on 21 November 1904.[100]
  68. ^ The Imperial Russia also tried to purchase Argentine cruisers General Belgrano and Pueyrredón, and Chilean cruisers Esmeralda and Chacabuco, all of which were also blocked by Great Britain.[106][105]
  69. ^ Being in the Giuseppe Garibaldi class of armoured cruisers, and ordered by Argentina with the likelihood of facing the Chilean battleships in mind, they were the forerunners of the later battlecruisers. The design prioritised on heavy armour at the expense of speed and cruise range which were important for other designs for commerce raiding/protection. The Royal Italian Navy ranked this class of warships as 2nd-class battleships.[107]
  70. ^ Effectively replacing the two battleships previously lost in the war, the Hatsuse and Yashima.
  71. ^ He was credited with this invention as he spearheaded its development program as one of the leaders of IJN (as the senior member of Navy General Staff), together with Navy Minister (Admiral) Yamamoto Gonnohyōe who appointed Tōgō Heihachirō to the Commander in Chief of the Combined Fleet disregarding seniority ranking within IJN. He was a major proponent of Anglo-Japanese Alliance after having attended the Greenwich Naval Academy for a period, and was the key figure in IJN's tight relationship with Armstrong Mitchell & Company.
  72. ^ After hitting Russian bettleship Peresvet 13 times with 12" and 15 more times with 6" or 8" shells;[112] hitting Retvizan 18 times, Tsesarevich 15 times,[113] Poltava 12–14 times, and Pobeda 11 times with 8" and larger armour-piercing shells with delayed detonation fuze without being able to sink any of them (likewise none of the Japanese battleships was sunk despite receiving many hits) in the Battle of the Yellow Sea, the Japanese tactical priority shifted from sinking to the destruction of superstructure. This concept of high explosive incendiary shells (The first example of what is called the HEI-BF "High Explosive Incendiary – Base Fuze" shells today) was not used by any navy in the world at the time. The Russian Navy used what is known as Makarov tip on its shells to improve penetrating performance upon hitting the target at an angle, without the experience of high explosive armour-piercing shells not being effective enough against the Harvey / Krupp armour and compartmented hull used on the battleships.
  73. ^ Shimose Masachika also experienced an accidental explosion in 1887 and had lost dexterity on the left fingers. ja:下瀬雅允
  74. ^ On Christmas day on Julian Calendar in 1904 off Madagascar, Alexey Novikov-Priboy onboard battleship Oryol wrote: "At noon, the ocean expanse was filled with the thunder of guns. Each ship fired a salute of thirty-one shots. The squadron was enveloped in black powder smoke."[96]
  75. ^ 12" shells creating an "incomparably larger splash than the enemy's on the water"[116]
  76. ^ "Japanese shells exploded even when they hit the water."[34]
  77. ^ 12" shells creating a "tall splash of 10–20 m"[117]
  78. ^ These shells held 5.3 kg[119] of guncotton, compared to 19.3 kg of Shimose powder for the Armstrong 12".[120]
  79. ^ See Armstrong Whitworth 12-inch 40-calibre naval gun for details.
  80. ^ Battleship Shikishima still experienced this problem and lost a gun in the battle.
  81. ^ When the trajectory is nearly flat, the shot hits the target even with a large range dispersion (+-100m or more at 10km range) because the height of the target ship effectively enlarges the target size. There is no such effect for the fall angles closer to 90 degrees no matter how tall the target is.

  83. ^ After the Nebogatov surrender, the Second in Command of battleship Oryol, Captain 2nd Rank K.L.Schwede, who was in charge of the ship at the surrender (the ship commander Captain 1st Rank N.Yung was seriously wounded and unconscious.) was interviewed by Captain T.Nomoto[cd] on battleship Asahi. It turned out they knew each other from previous assignments of Nomoto in Russia. Schwede desperately wanted to know why the Japanese shots had so much better hit rates in the battle. Nomoto did not (or could not) explain and just boasted "Our guns are meant and made to hit the target."[123]

As Oldhamire was carrying 150,000 cans of oil destined for Japan, she became subject of a maritime capture, and was forced to join the fleet with Russian officers onboard. The removed captain, the chief engineer, and two more British personnel were kept in captivity onboard the hospital ship Orel.

IJN concealed the loss and gave the 'Akatsuki' name to the captured Reshitel‘nyi as if the original returned to service. At the beginning of this battle, there was a plan to dispatch Akatsuki, being indistinguishable from other Russian destroyers, in front of the Baltic Fleet to lay chained floating mines.[z] Tōgō did not use this ploy, and the destroyer was added to the Navy list as Yamabiko (and Akatsuki struck) after the war.[176]
