A message written by Pope Francis in the Fosse Ardeatine (Ardeatine Caves), the site of a 1944 massacre carried out by German troops occupying Rome in retaliation for a partisan attack on an SS battalion the day before, reads, in Italian: "Questi sono I frutti della guerra: odi, morte, vendette... Perdonaci, Signore" (These are the consequences of war: hate, death, vengeance... Forgive us, Lord), in Rome, Italy, Thursday, Nov. 2, 2017. Pope Francis is underlining the price of war, visiting an American military cemetery and the site of a Nazi massacre in Rome. The pope first said Mass in the American Cemetery, where 7,680 American war dead who helped liberate southern and central Italy during World War II are buried and 3,095 missing are commemorated.
