In the afternoon of the same day, Wednesday, June 7th, the Pope received, in a memorable and moving general audience in the Sala Clementina, some seven hundred grimy Allied soldiers, most of them fresh from battle and all of them in the highest spirits. There were British, French, Americans, Poles, Indians, and men from all the Dominions. The contrast between these varieties of battle-dress and the plumed Swiss Guard in their sixteenth-century uniforms who marshalled them made the deepest impression : here were the centuries meeting, as well as the nations of the free world, at an historic moment in history. The Pope said in English from the throne : “We bless all you here in person, and We send Our blessing to your loved ones at home. We pray that God in His love and mercy may be with you always. Goodbye. Bless you all.” Then he administered the Apostolic Benediction as the soldiers knelt, and came down from the throne, passing among the men as he made his way to leave. Hundreds of soldiers pressed round the common father, trying to kiss his hand or his cassock, and altogether too enthusiastic for the Swiss Guard ; but the Pope himself was entirely unperturbed, smiling, and speaking all the time to those nearest to him. Every soldier who attended was given a rosary which he had specially blessed, in a little envelope bearing the papal crest.
The Tablet, June 17, 1944
The Italian theatre of operations was the forgotten theatre of operations in World War II Europe. The American, British, Poles, New Zealanders, Australians, South Africans, Brazilians and other Allied troops fought a long and grinding campaign against a formidable German defense, with advances often painfully won from mountain top to mountain top, up the tough spine of the Italian boot. Typical of how events in Italy were overshadowed by events elsewhere in Europe was the liberation of Rome on June 5, 1944, a very hard won objective of the Allied 5th American Army and the 8th British Army, which was immediately overshadowed by D-Day the next day.
