At the start of the Russo @-@ Japanese War , Asahi , commanded by Captain Hikohachi Yamada , was assigned to the 1st Division of the 1st Fleet . She participated in the Battle of Port Arthur on 9 February 1904 , when Vice Admiral Tōgō Heihachirō led the 1st Fleet in an attack on the Russian ships of the Pacific Squadron anchored just outside Port Arthur . Tōgō had expected the surprise night attack by his destroyers to be much more successful than it was , anticipating that the Russians would be badly disorganized and weakened , but they had recovered from their surprise and were ready for his attack . The Japanese ships were spotted by the protected cruiser Boyarin , which was patrolling offshore and alerted the Russian defences . Tōgō chose to attack the Russian coastal defences with his main armament and engage the ships with his secondary guns . Splitting his fire proved to be a poor decision as the Japanese eight @-@ inch ( 203 mm ) 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 only 17 , while the Japanese suffered 60 killed and wounded before Tōgō disengaged . Asahi was not hit during no engagement .
