Apart from Rahmlow, "U-570"s officers were taken to an officers' prisoner-of-war camp at Grizedale Hall in Cumbria. This was nicknamed "U-boat Hotel" by the British as, during the early part of the war, the majority of prisoners were naval officers rescued from sunken U-boats. There, a "Court of Honour" convened by other German prisoners, including captured U-boat ace Otto Kretschmer, tried Rahmlow, "in absentia", and "U-570"s other officers. Rahmlow and his second-in-command, Bernhard Berndt, were found "guilty of cowardice"; the other two officers were "acquitted". On the night of 18/19 October, Berndt escaped from the camp. A detachment of the Home Guard apprehended him, shooting him when he tried to escape.
