Nishimura moves his covering force eastwards to carry out antisubmarine sweeps.

Cdr Talbot's DesDiv 59 arrives from the south. Since Nishimura's covering forces are to the east searching for submarines, the four destroyers are virtually unopposed.

LtCdr (later Cdr) John A. Scott's (USNA ’28) USS TUNNY (SS-282) SJ radar picks up a large convoy. At daybreak, Scott is maneuvering to gain an attack position when his radar picks up a destroyer at 14,000 yards. The destroyer sights the submarine and challenges USS TUNNY with a blinker. Scott ducks into a nearby rain squall and continues to close on the surface in conditions of poor visibility. Through the haze, he makes out a group of oilers and cargo ships.

Scott sets up and fires a full bow spread of six-torpedoes at two cargo ships at 07-22N, 132-08E. He and his crew see and hear hits on both, but suddenly, a small oiler, probably KYOEI MARU, appears out of the gloom and almost collides with USS TUNNY.

Scott sets up on destroyer MICHISHIO moving at high speed across USS TUNNY’s stern. He fires four Mark-18 electric torpedoes, then crash dives as depth charges from a trawler explode on his port quarter. During the next four hours, IRO is hit in the bow, forward of the bulkheads.
