10 August 1944:
Off Cape Bolinao, NW coast of Luzon, Philippines. At 0940, LtCdr (later Captain) Enrique D. Haskins’ (USNA ’33) USS GUITARRO (SS-363) detects a large unidentified convoy with surface and air escorts coming up from the south along the coastline. At 1029 (H), Haskins maneuvers from beachside and launches four stern torpedoes at a KATORI-class light cruiser and an overlapping merchant ship. Haskins last torpedo hits SHINEI MARU. She explodes and burns as USS GUITARRO dives to avoid depth charges. SHINEI MARU sinks at 16-15N, 119-45E. Only one crewman is KIA.
USS GUITARRO suffers minor exterior damage and depart the area. 
 Haskins claimed two hits on the light cruiser, but received no credit post-war. Based on his ID of a “KATORI-class light cruiser”, the convoy may have been HI-70 which departed Singapore for Moji at 2100 on 4 Aug '44 consisting of five tankers and three cargo ships escorted by light cruiser KASHII, escort carrier SHINYO, destroyer SHIMOTSUKI and kaibokan CHIBURI, SADO, CD-13 and CD-19 arriving at Moji at 1430 on 15 Aug '44, but there is no known Japanese documentation of his attack to support this speculation.
Thanks go to Gilbert Casse of France.
