The later was hit in No. 6 hold by a bomb, splinters from others that landed to port alongside the same hold added to the fires raised.

The covering force moves eastwards to carry out antisubmarine sweeps.
Cdr Talbot's DesDiv 59 arrives from the south. At 0316, they begin their first attack firing their 4-inch guns and launching ten torpedoes at the anchored transports, but all their torpedoes miss. Talbot orders another attack. At 0330, at 00-10N, 118-00E USS POPE hits and sinks SUMANOURA MARU. Many troops are KIA and only nine of her crew of navy sailors survive. Captain Shibuya Shunsaku (36) is KIA and posthumously promoted Rear Admiral.
At 0335, USS PARROTT and USS PAUL JONES hit transport TATSUKAMI MARU with torpedoes in a deep fuel tank, the resultant flooding caused her to sink by the stern, and four of her crew lost their lives. USS POPE and USS PARROTT sink the 2nd Base Force's patrol boat PB-37 (casualties unknown) with torpedoes and gunfire.
At 0345, USS JOHN D. FORD sinks transport KURETAKE MARU with gunfire and torpedoes. Six crewmen and 272 troops are KIA. ASAHISAN MARU suffers damage from gunfire and torpedoes but remains afloat.
