Battle of Port Arthur
On the night of 8 February 1904, in the Battle of Port Arthur, the opening battle of the Russo-Japanese War, Imperial Japanese Navy destroyers launched a pre-emptive strike on the First Pacific Squadron anchored in the roadstead outside Port Arthur. Admiral Oskar Stark sent a squadron that included "Boyarin" in pursuit, but it succeeded only in attacking a Russian destroyer heading into port before returning to Port Arthur.
