Battle of Port Arthur

The Battle of Port Arthur (Japanese: 旅順港海戦 / 旅順口海戦 Ryojunkō Kaisen or 旅順港外海戦, Ryojunkōgai Kaisen, 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 Russian fleet anchored at Port Arthur, Manchuria, and continued with an engagement of major surface combatants the following morning; further skirmishing off Port Arthur would continue until May 1904. The battle itself ended inconclusively, though later event would result in the war ending in a Japanese victory. For a major European power to lose to the Japanese was not only inconceivable to the world at large but also fraught with dire circumstances for the Imperial regime; the Russian people, from the nobility down to the recently-emancipated serfs, lost confidence in the military and in the Tsarist political system. This led directly to the Russian Revolution of 1905, and would be well-remembered upon yet-more-disastrous defeats to come later in World War I.
