Here they were spotted by the Japanese Combined Fleet of Admiral Tōgō Heihachirō, which engaged them in battle, sinking 7 of the 11 Russian battleships for no major losses. The remnants of the Russian fleet were mostly destroyed or captured the following day, with only three warships making it through to Vladivostok.
