Authors’ Note:
[1] LtCdr Abele and USS GRUNION were lost on this, USS GRUNION's first war patrol. Japanese sources indicate that on 30 July 1942, USS GRUNION was sunk by the deck gun of freighter KANO MARU after the submarine attacked the maru with dud Mark XIV torpedoes, then surfaced to engage with her own deck gun. KANO MARU herself, was sunk a week later at Kiska Harbor by USN PBY "Catalinas".

Grateful thanks to Mr. Gilbert Casse of France. Thanks go to Bruce Abele, son of LtCdr Abele, for identifying CH-27's final CO, Lt Shinoda Isamu. Abele also located Shinoda's son and 97-year old widow, Shinoda Chiyo, shown below with pressed flowers from Kiska sent by the sons of Catherine E. Abele.
