The Following Excerpt is from the Unternehman Kriegstagebuch of OberLeutnant zur See Karl Jobst U-2326 a Type XXIII ( simply put they were unable on the 6th of May 1945 to receive Elektra/Sonne and the following day in heavy fog and mist surfaced their boat to figure out their position by using Nautical charts and visual bearings )
