The list was printed as a supplement or appendix to the secret Informationsheft G.B. handbook, which Schellenberg also claimed to have written. This handbook noted opportunities for looting, and named potentially dangerous anti-Nazi institutions including Masonic lodges, the Church of England and the Boy Scouts. On 17 September 1940, SS-Brigadeführer Dr Franz Six was designated to a position in London where he would implement the post-invasion arrests and actions against institutions, but on the same day, Hitler postponed the invasion indefinitely.[5] In September 1945, at the end of the war, the list was discovered in Berlin.
