The ferry is escorted by an unidentified subchaser leading the way and CD-112 as rear guard.

Off the S coast of Karafuto. At 1110, Cdr (later Rear Admiral/MOH) Eugene B. Fluckey's (USNA ’35) USS BARB (SS-220) sights the small convoy, coming down the coast at 12 knots, Fluckey sets up and, at about noon, fires two torpedoes at CD-112. One torpedo explodes on the nearby shore close to the mouth of the Magotsue River. A second torpedo is seen approaching the flank of SOYA MARU.

CD-112, immediately goes to flank speed and deliberately intercepts the approaching torpedo to save the many helpless women and children on board the ferry from certain death. Seconds later, CD-112 is hit aft below her DC racks, followed by a huge explosion and heavy black smoke. For about 10 minutes, part of her bow remains above water before she sinks by the stern in shallow water at 46-03N, 142-16E (6 km off Magotsue Village). CD-112’s CO, Cdr Ishiwatari Shunichiro and 199 of his brave crew are KIA. He is likely promoted Captain posthumously.

SOYA MARU makes up maximum speed and escapes. Fluckey fires his last three torpedoes at the ferry, but misses. About three hours later the ferry safely arrives at Odomari. After receiving news about the sinking of CD-112, kaibokan SHIMUSHU and two other units race to the scene. SHIMUSHU rescues two surviving sailors, while the other units rescue another two survivors.
