The Battle of Port Arthur (Japanese: 旅順口海戦, Hepburn: Ryojunkō Kaisen)^[2] of 8–9 February 1904 marked the commencement of the Russo-Japanese War. It began with a surprise night attack by a squadron of Japanese destroyers on the neutral Russian fleet anchored at Port Arthur, Manchuria, and continued with an engagement the following morning; further skirmishing off Port Arthur would continue until May 1904. The attack ended inconclusively, though the war resulted in a decisive Japanese victory.
