From Wikimedia Commons: [“This picture is more than 40 years old and was taken at Arlington National Cemetery. There are similar grave yards around the USA and throughout Europe and the Pacific. Many of these people died in their 2nd decade of life, never to know another Christmas gathering with their loved ones. They did so that we might have our freedom and celebrations. Remember them on December 25.” (Taken from a slide)]
