Cdr (later Rear Admiral-Ret) Richard H. O’Kane’s (USNA ’34) USS TANG (SS-306), running on the surface,is spotted by the lookouts from CD-46. Alerted by a signal flare, the entire convoy commences an emergency turn to starboard.
At 0208, USS TANG torpedoes and sinks EBARA MARU at 25-04N, 119-35E. Eleven crewmen are KIA. MATSUMOTO MARU, following behind EBARA MARU, alters course intent on
ramming USS TANG, but one of the torpedoes fired at EBARA MARU strikes onrushing
MATSUMOTO MARU’s No. 1 hold. Her bow plunges under and she comes to a halt. Two
machine guns on her bridge open fire and drive the submarine under where the
water depth is a mere 131 feet.
Aboard HAKUSA, the convoy commodore orders the convoy dissolved. CD-34 is tasked with the rescue of survivors and conducting anti-submarine operations in the area. One cutter and a 6-meter motor boat are lowered to pick up the survivors of MATSUMOTO and EBARA MARUs. USS TANG commences another attack, but one of her remaining torpedoes commences a circular run. The lookouts on CD-34 first spot the torpedo and then witness an explosion, which sinks the submarine.
The convoy speeds onward. Nine American submariners are found drifting on the surface including Captain O’Kane. CD-34 rescues the survivors and later claims to have sunk USS TANG, but, in fact, the submarine was sunk by a defective Mark-18 torpedo that happened to be USS TANG's very last torpedo.
