The branch office in Bern, Switzerland, began gathering reports, including some that were smuggled out of the camps, for a book called Kreuzzug gegen das Christentum (Crusade Against Christianity), an exposé of Nazi crimes.
Šveitsi harubüroo Bernis hakkas koguma sellekohaseid aruandeid, sealhulgas koonduslaagritest välja smugeldatud tunnistusi raamatu jaoks „Kreuzzug gegen das Christentum ” (Ristisõda kristluse vastu), mis paljastas natside kuritegusid.
