Location
Cause → Event → Consequence
The Russian Pacific Fleet at Port Arthur sought to break free from the Japanese naval blockade and unite with the Vladivostok squadron, which would have consolidated Russian naval strength in the region and threatened Japanese supply lines during the Russo-Japanese War.
On 10 August 1904, the Russian fleet sortied from Port Arthur into the Yellow Sea but was intercepted by the Imperial Japanese Navy. The ensuing engagement prevented the Russian ships from completing their breakout, forcing them to turn back to port after suffering damage in the fighting.
The Russian Port Arthur fleet was compelled to return to anchor, and four days later the Battle off Ulsan similarly neutralized the Vladivostok squadron's sortie. Both Russian fleets were effectively bottled up, leaving Japan in firm control of the sea lanes and weakening Russia's strategic position in the war.
