O ne of the main aims of the camp resistance was to keep written documents which would prove the cruelties committed by the SS.

Those reports were mainly written by Polish prisoners and smuggled out of the camp - usually because of contacts that some Poles had with people living outside the camp. Thus, the world was delivered messages and informations about the deportations, the inmates' nationalities, the life conditions in the camp and the mass murder. Most of the SS-guards were also identified by these contacts.

A report called "Auschwitz Hangman" dated from September 16, 1944, names the identities of the SS-staff, starting with the camp commander Rudolf H: "We deliver a rough enumeration of the hangmen of Auschwitz. All data are undoubtedly authentic. London should as soon as possible demand death penalty for these murderers." (Swiebocka, page 176)
