The rest of the convoy is diverted from Takao and arrives at Kirun (Keelung) later that day.

Removed from the Navy List.

Authors' Notes:
[1] Salvage tug HASHIMA was renamed KASASHIMA to avoid confusion when cable-minelayer HASHIMA was completed on 25 October 1940.

Little data were found for tug KASASHIMA's assignments or movements. Readers with access to any such data are requested to post the information on the Discussion and Questions board or's IJN Ship Message Board

Thanks go to Gengoro S. Toda for clearing up the confusion caused by the two ship's names.
