Imperial Russian Navy - Russo-Japanese War

Russo-Japanese War

On the night of February 8, 1904, the Japanese naval fleet under Admiral Heihachiro Togo opened the war with a surprise attack by torpedo boat destroyers on the Russian ships at Port Arthur, badly damaging two Russian battleships. The attacks developed into the Battle of Port Arthur the next morning. A series of indecisive naval engagements followed, in which the Japanese were unable to attack the Russian fleet successfully under shore batteries (coastal guns) of the harbor and the Russians declined to leave the harbor for the open seas, especially after the death of Admiral Stepan Osipovich Makarov on 13 April 1904.

After the attack on Port Arthur, the Japanese attempted to deny the Russians use of the port. On the night of 13/14 February, the Japanese attempted to block the entrance to Port Arthur by sinking several cement-filled steamers in the deep water channel to the port. But the steamers, driven off course by Russian gunfire were unable to sink them in the designated places, rendering them ineffective. Another attempt to block the harbor entrance on the night of 3/4 May with blockships also failed.
