While retiring with "Irresistible"s survivors aboard, "Ocean" herself was hit by an artillery shell fired by Seyit Çabuk, an Ottoman Army gunner and struck a drifting mine at around 19:00. Her starboard coal bunkers and passageways flooded, her steering jammed hard to port, and she took on a list of 15° to starboard. She came under fire from shore and began taking hits, which flooded her starboard engine room and prevented steering repairs. The destroyers , , and came alongside and took off her crew (and the survivors from "Irresistible") at around 19:30. She then drifted into Morto Bay, still under fire, and sank there unobserved by Allied forces at about 22:30. When destroyer "Jed" entered the bay later that evening to sink "Ocean" and "Irresistible" with torpedoes so that they could not be captured by the Turks, the two battleships were nowhere to be found.
