I am currently very interested in U-boats and am studying about them. A U-175 sailor asks to be rescued after his boat was sunk while preparing to attack Convoy HX-233 on 17 April 1943.  USCGC Spencer detected U-175 ahead of the convoy and conducted two depth charge attacks.  Forty minutes later the boat was forced to surface and was scuttled by her crew.  Spencer and USCGC Duane rescued 44 survivors
