バラバク海峡
After refitting at Majuro from 14 August to 6 September 1944, "Cobia" sailed into the Luzon Strait for her second war patrol, a mission frequently punctuated by attacks by Japanese aircraft. On 22 October, the sub rescued two survivors of a Japanese ship previously sunk by another American submarine. "Cobia" put into Fremantle for refit 5 November, and cleared that harbor on her third war patrol 30 November. Sailing into the South China Sea, she reconnoitered off Balabac Strait between 12 December and 8 January 1945, and on 14 January sank the minelayer "Yurishima" off the southeast coast of Malaya. Surfacing to photograph her sinking victim, "Cobia" was driven under by a Japanese bomber. Next day she rescued two Japanese from a raft on which they had been adrift 40 days.
