However, in a bomber attack by the Allies, the abbey is destroyed, leading to public outcry and, post-bombing, as shelter for the Nazis.
Advancing in Italy toward Rome, the Allies attack the Gustav Line, held by the Axis, at the mountain town of Monte Cassino, home to a Benedictine abbey dating to 524 A.D. Evacuated by the Germans, both sides tell the Vatican it will not be attacked or used in military operations. However, in a bomber attack by the Allies, the abbey is destroyed, leading to public outcry and, post-bombing, as shelter for the Nazis. Polish troops capture the abbey on May 18, leading the way for the Allied capture of Rome soon after.
