http://home.earthlink.net/~nbrass1/4enigma.htm Not knowing that the British had lost him, Admiral Lütjens assumed they knew where he was. He transmitted a coded message detailing his shortage of fuel and that his destination was France. The code used was not readable by BP, but the length of transmission afforded plenty of time to obtain RDF fixes on his position; however, the report was somehow mishandled, and British forces went searching in the wrong direction. A cardinal rule in sending coded messages is never to transmit the same text in two different ciphers.In a response to an inquiry from Luftwaffe Chief of Staff General Hans Jeschonnek, who may have had a relative on board Bismarck, the message was repeated in the Luftwaffe cipher, which the British could read. One of the last messages from the Bismarck read: KRKRX FLOTT ENCHE FANAN OKMM XXTOR PEDOT REFFE RACHT ERAUS XSCHI FFMAN OEVRI ERUNF AEHIG XWIRK AEMPF ENBIS ZURLE TZTEN GRANA TEXES LEBED ERFUE HRERX "Commander-in-Chief Fleet to Naval Headquarters: Torpedo hit right aft. Ship unmaneuverable. We fight to the last shell. Long live the Führer"
