Battle of the Yellow Sea

Battle context

The Battle of the Yellow Sea denied the Russian Pacific Fleet its primary operational objective: combining the Lüshunkou squadron with the Vladivostok squadron into a unified force. The Russian breakout attempt failed, and the fleet was driven back to port. Four days later, the Battle off Ulsan neutralized the Vladivostok group as well, leaving both Russian naval formations confined to anchorage. Together the two engagements effectively ended Russian naval offensive capacity in the Pacific theater, ceding sea control to Japan and tightening the strategic encirclement of Port Arthur that would define the land campaign through the remainder of 1904.
