Between late February and early March 1945, with the advance of the Allied armies, all production of notes at Sachsenhausen ceased. The equipment and supplies were packed and transported, with the prisoners, to the Mauthausen-Gusen concentration camp in Austria, arriving on 12 March. Shortly afterwards Krüger arranged for a further transfer to the Redl-Zipf series of tunnels where they were to restart production. The order to resume production was soon rescinded, and the prisoners were ordered to destroy the cases of money they had with them. That which was not burnt by the prisoners was loaded onto trucks with the printing equipment and sunk in the Toplitz and Grundlsee lakes.
