Authors’ Notes:
[1] LtCdr Merrill K. Clementson’s was unaware that the two ships in the harbor were damaged TOKAI and NICHIYO MARUs. On 27 Jan ’43, LtCdr (later Vice Admiral) Glynn R. Donaho’s (USNA ’27) USS FLYING FISH (SS-229) fired two torpedoes at TOKAI MARU anchored in Apra Harbor and got one hit that caused damage, but did not sink her. It is unknown what sort damage, if any, immobilized NICHIYO MARU before Clementson’s attack, perhaps engine trouble.

Thanks go to Erich Muehlthaler of Germany.
