Hi Captain Duffy,

I googled K-14 and the first hit was [www.fishermensvoice.com].

It doesn’t definitely attribute her loss to a U-boat and its source is the “Eastern Sea Frontier - Northern Group Reports (War Diary) July, 1944, National Archives and Records Administration”.

If it was a U-boat perhaps nobody has ever figured out which one for sure although there is speculation that U-233 (lost roughly in that area 3 days later) did it. Of course her KTB would still be aboard so we can't know for sure.

Regards,

Ken Dunn
