entry by Peter Cundall: Gyoun Maru (1890, 912 gt) was formerly Moller's Ethel Moller seized in December 1941. The intelligence report is mostly correct. The ship was in convoy TA-406 from Shanghai and sailed to Takao (Kaohsiung) as one of 4 ships. The same ships then sailed to Hong Kong as convoy No.91. En route on 4 July the ships were attacked by Seahorse and three of the four ships in the convoy (Nitto Maru, Kyodo Maru No.28 and Gyoyu Maru (ex Joan Moller)) were torpedoed and sunk. Gyoun Maru and escorting destroyer Kuri and torpedo boat Hatsukari arrived at Hong Kong at 1540 on 5 July (NB not 20 July).
