A letter found among the private papers of Pope Pius XII suggests that the Holy See was told in 1942 that up to 6,000 people, “above all Poles and Jews,” were being killed in furnaces every day at Belzec, a Nazi death camp in Poland.
Though news of the atrocities being perpetrated by Hitler was already reaching Pope Pius XII’s ears, this information was especially important because it came from a trusted church source based in Germany, said Giovanni Coco, a Vatican archivist who discovered the letter. The source was “in the heart of the enemy territory,” Mr. Coco said on Saturday.
