The Japanese warships withdrew with Makarov in pursuit. As Makarov caught up to the Japanese fleet, the thick fog that blanketed the sea lifted to reveal the Japanese trap: Admiral Togo was waiting with his capital ship and five additional battleships, plus six additional first-class cruisers bringing up the rear. Makarov quickly turned his force around and fled back to the safety of Port Arthur's harbour. As "Petropavlovsk" moved closer to the harbour's entrance, she detonated a Japanese mine that his men had failed to clear as he had instructed. Secondary explosions followed quickly in succession and "Petropavlovsk" sank, taking Admiral Makarov with her.
