06:07 Third and fourth torpedo came, hit fore bridge and amidships on the port but both dud. The Grunion intended to surface and sink by gunfire, ripples was seen 400m distance from her. Kano Maru had two old 8cm guns on forecastle and stern. Stern's one malfunction by the torpedo shock, but forecastle gun fired to the periscope. 13mm machine guns on bridge fired as well. Before the sub appear the whole, fourth shot from Kano Maru hit the conning tower of the sub. It is thought the last of Grunion. The attack had ceased. Later rescue came from Kiska, three seaplanes, cable layer Ukishima, and sub chaser No. 26.
Sounds like another US WWII sub lost due to the dud torpedoes that plagued the fleet early in the war.
