During the Second World War SS Intelligence developed a secret weapon to undermine and ruin the British war effort – it was a weapon made of paper. Operation Bernhard – the Nazi codename for this covert project – became the biggest currency forgery in history, counterfeiting, at today’s value, over three billion pounds. The 104-strong workforce who produced the money were all Jewish prisoners isolated in a special workshop at Sachsenhausen concentration camp near Berlin. With the threat of death hanging over them they skilfully printed banknotes, which the Bank of England described as: “the most dangerous forgeries ever seen”.
