In Dachau: The Official History 1933–1945, Paul Berben wrote that clergy were watched closely, and frequently denounced, arrested and sent to Nazi concentration camps: "One priest was imprisoned in Dachau for having stated that there were good folk in England too; another suffered the same fate for warning a girl who wanted to marry an S.S. man after abjuring the Catholic faith; yet another because he conducted a service for a deceased communist".
