Splitting his fire proved to be a poor decision as the Japanese eight- and six-inch guns inflicted little damage on the Russian ships, which concentrated all their fire on the Japanese ships with some effect. Although many ships on both sides were hit, Russian casualties numbered some 150, while the Japanese suffered roughly 90 killed and wounded before Tōgō disengaged.

. Jessen was ordered to rendezvous with them, but the order was delayed. His three armored cruisers, , , and , had to raise steam, so he did not sortie until the evening of 13 August. By dawn he had reached Tsushima, but turned back when he failed to see any ships from the Port Arthur squadron. north of the island he encountered Kamimura's squadron, which consisted of four modern armored cruisers, , , , and ''Iwate''. The two squadrons had passed during the night without spotting one another and each had reversed course around first light. This put the Japanese ships astride the Russian route to Vladivostok.
Jessen ordered his ships to turn to the northeast when he spotted the Japanese at 05:00 and they followed suit, albeit on a slightly converging course. Both sides opened fire around 05:23 at a range of . The Japanese ships concentrated their fire on ''Rurik'', the rear ship of the Russian formation. She was hit fairly quickly and began to fall astern of the other two ships. Jessen turned southeast in an attempt to open the range, but this blinded the Russian gunners with the rising sun and prevented any of their broadside guns from bearing on the Japanese. About 06:00, Jessen turned 180° to starboard in an attempt to reach the Korean coast and to allow ''Rurik'' to rejoin the squadron. Kamimura followed suit around 06:10, but turned to port, which opened the range between the squadrons. ''Azuma'' then developed engine problems and the Japanese squadron slowed to conform with her best speed. Firing recommenced at 06:24 and ''Rurik'' was hit three times in the stern, flooding her steering compartment; she had to be steered with her engines. Her speed continued to decrease, further exposing her to Japanese fire, and her steering jammed to port around 06:40.
Jessen made another 180° turn in an attempt to interpose his two ships between the Japanese and ''Rurik'', but the latter ship suddenly turn to starboard and increased speed and passed between Jessen's ships and the Japanese. Kamimura turned 180° as well so that both squadrons were heading southeast on parallel courses, but Jessen quickly made another 180° turn so that they headed on opposing courses. At this time an eight-inch shell struck the roof of ''Iwate''s starboard forward upper six-inch casemate and ignited the ready-use ammunition. The fire killed 40 and wounded 24 more and knocked out the six-inch gun in that casemate, as well as those below and aft of it. In addition, the 12-pounder above it was rendered inoperable. The Russians reversed course for the third time around 07:45 in another attempt to support ''Rurik'' although ''Rossia'' was on fire herself; her fires were extinguished about twenty minutes later. Kamimura circled ''Rurik'' to the south at 08:00 and allowed the other two Russian ships to get to his north and gave them an uncontested route to Vladivostok. Despite this, Jessen turned back once more at 08:15 and ordered ''Rurik'' to make her own way back to Vladivostok before turning north at his maximum speed, about .[Brook 2000, p. 43]
About this time Kamimura's two elderly protected cruisers, and , were approaching from the south. Their arrival allowed Kamimura to pursue Jessen with all of his armored cruisers while the two new arrivals dealt with ''Rurik''. They fought a running battle with the Russians for the next hour and a half; scoring enough hits on them to force their speed down to . The Japanese closed to a minimum of about , but Kamimura then opened the range up to .[
About 10:00, Kamimura's gunnery officer erroneously informed him that ''Izumo'' had expended three-quarters of her ammunition and he turned back after a five-minute rapid-fire barrage. He did not wish to leave the Tsushima Strait unguarded and thought that he could use his remaining ammunition on ''Rurik''. By this time she had been sunk by ''Naniwa'' and ''Takachiho''. They had radioed Kamimura that she was sunk, but he did not receive the message. Shortly after the Japanese turned back, ''Gromoboi'' and ''Rossia'' were forced to heave-to to make repairs. ''Iwate'' was the most seriously damaged Japanese ship and suffered a total of 40 killed and 37 wounded.
In mid-September, ''Tokiwa'' and ''Iwate'' were transferred to the 1st Division. In early December the cruiser was sent home to refit. In mid-February, she was guarding the Tsugaru Strait and remained there through mid-April.

The cruiser also fired upon the battleship before 14:50. The protected cruiser attempted to make a torpedo attack at about 15:06, but was driven off by fire from ''Iwate'' and the armored cruisers and . The battleship suddenly appeared out of the mist at 15:35 at a range of about . All of Kamimura's ships engaged her for five minutes or so with ''Azuma'' and the armored cruiser also firing torpedoes at the Russian ship without effect.
After 17:30 Kamimura led his division in a fruitless pursuit of some of the Russian cruisers, leaving Tōgō's battleships to their own devices. He abandoned his chase around 18:03 and turned northwards to rejoin Tōgō. His ships spotted the rear of the Russian battleline around 18:30 and opened fire when the range closed to 8000–9000 meters. Nothing is known of any effect on the Russians and they ceased fire by 19:30 and rejoined Tōgō at 20:08 as night was falling. The surviving Russian ships were spotted the next morning and the Japanese ships opened fire around 10:30, staying beyond the range at which the Russian ships could effectively reply. Rear Admiral Nikolai Nebogatov
Nikolai Ivanovich Nebogatov (; occasionally transliterated as Nebogatoff; April 20, 1849 – August 4, 1922) was a rear admiral in the Imperial Russian Navy, noted for his role in the final stages of the Russo-Japanese War of 1904–1905.

therefore decided to surrender his ships as he could neither return fire nor close the range.
In the meantime, the coast defense ship had fallen well behind Nebogatov's ships and was spotted by the protected cruiser early in the morning, but the Japanese were more intent on locating the main body of the Russian fleet than attacking a single isolated ship. ''Admiral Ushakov'' was then spotted at 14:10, well after Nebogatov's surrender, by Shimamura who received permission to pursue her with ''Iwate'' and ''Yakumo''. They caught up with the Russian ship at 17:00 and demanded her surrender. ''Admiral Ushakov'' attempted to close the range to bring the Japanese cruisers within range of her guns, but they were fast enough to keep the range open and the Russian ship never hit either one. After about half an hour, ''Admiral Ushakov'' was listing heavily enough that her guns could not elevate enough to bear and her commander ordered his crew to abandon ship and the scuttling

charges detonated. The ship sank in three minutes and 12 officers and 327 crewmen were rescued by the Japanese. Between them, ''Yakumo'' and ''Iwate'' fired 89 eight- and 278 six-inch shells during the engagement. ''Iwate'' was struck 17 times, over the course of the entire battle, including hits that burst in the water alongside. She was, however, only lightly damaged by two hits that caused two compartments on the lower deck to flood.
