Several scenes were filmed in or near the Italian village Vittorio Veneto, including the battle scenes. Many of the extras playing the soldiers in the movie were airmen from nearby Aviano Air Base that volunteered to star in the movie.
This film's opening prologue states: "This film is based on a true story . . . NORTHERN ITALY 1918. Here, during the final year of World War One, Italy was defending itself alone against a massive Austrian invasion. America was one of Italy's allies but the US Army was already fully committed in France. So President Wilson sent in teams of Red Cross doctors and nurses to boost Italian morale and help care for the wounded. Young men across America responded to the President's call for further volunteers to drive red Cross ambulances and work in the front line canteens."
This movie's closing epilogue states: "Agnes von Kurowsky's long and distinguished career with the American Red Cross continued until the end of World War II. She remained unmarried until she was 36 and lived to be 92. Ernest Hemingway won the Nobel Peace Prize for Literature in 1954. One of his great novels, A FAREWELL TO ARMS, was inspired by his experiences in Italy during World War One. He married four times and took his own life in 1961."
