LtCdr Gunn tracks the submarine for over three hours and attempts an "end-around" to outrun the target and reach a favorable firing position. SCABBARDFISH is spotted by a Japanese aircraft (that fails or is unable to warn I-365). Gunn is forced to dive, but finishes his approach submerged and launches two stern torpedoes at 1,625-yards. At 0940, a torpedo explodes on the Japanese submarine's starboard side in the forward battery compartment. I-365 sinks in 30 seconds at 34-44N, 141-01E.
