These dispositions culminated with the Russo-Japanese War (1904–1905). The battleship "Mikasa" was the flagship of admiral Tōgō Heihachirō. At the Battle of Tsushima, the Mikasa with Admiral Tōgō led the Combined Fleet of the Imperial Japanese Navy into what has been called "the most decisive naval battle in history". The Russian fleet was almost completely annihilated: out of 38 Russian ships, 21 were sunk, 7 captured, 6 disarmed, 4,545 Russian servicemen died and 6,106 were taken prisoner. On the other hand, the Japanese only lost 117 men and 3 torpedo boats. This overwhelming victory made admiral Tōgō one of Japan's greatest naval heroes.
