In early 1945 the unit was moved to Mauthausen-Gusen concentration camp in Austria, then to the Redl-Zipf series of tunnels and finally to Ebensee concentration camp. Because of an overly precise interpretation of a German order, the prisoners were not executed on their arrival; they were liberated shortly afterwards by the American Army. Much of the output of the unit was dumped into the Toplitz and Grundlsee lakes at the end of the war, but enough went into general circulation that the Bank of England stopped releasing new notes and issued a new design after the war.
