Beginning in 1942 Nazi Germany devised Operation Bernhard, a plan to bomb and demolish the British economy. Using prisoners primarily from Sachsenhausen but also Auschwitz and other concentration camps, SS Major Krüger directed a team of about 140 prisoners to forge £5, £10, £20 and £50 notes which, at the program’s end in 1945, would end up totaling £134,610,810. The forged notes are considered the best counterfeits ever produced, being virtually indistinguishable from official Bank of England notes. The notes were never dropped on England, but were used by the Nazi foreign intelligence to pay for their activities. In early 1945 another similar operation was in the works to forge American $100 bills, but was cancelled one day after starting.
