Overview

The Battle of the Yellow Sea was a naval battle of the Russo-Japanese War, fought on 10 August 1904. In the Russian Navy, it was referred to as the Battle of 10 August. The battle foiled an attempt by the Russian fleet at Lüshunkou to break out and form up with the Vladivostok squadron, forcing them to return to port. Four days later, the Battle off Ulsan similarly ended the Vladivostok group's sortie, forcing both fleets to remain at anchor.

Significance

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.
