to condemn the recent wave of atrocities in Poland; when Cardinal Secretary of State Maglione replied that the Vatican could not document individual atrocities, Papée declared, "when something becomes notorious, proof is not required". Although Pius XII received frequent reports about atrocities committed by and/or against Catholics, his knowledge was incomplete; for example, he wept after the war on learning that Cardinal Hlond had banned German liturgical services in Poland. There was a well-known case of Jewish Rabbis who, seeking support against the Nazi persecution of Polish Jews in the General Government (Nazi-occupied Polish zone), complained to the representatives of the Catholic Church. The church's attempted intervention caused the Nazis to retaliate by arresting rabbis and deporting them to the death camp.

In the spring of 1940, a group of German generals seeking to overthrow Hitler and make peace with the British approached Pope Pius XII, who acted as an interlocutor between the British and the abortive
