I used to volunteer at the VA. One old grunt told me that they (I can't remember where), watched as ANGELS calmed the battlefield during Christmas circa 1917. He told me they actually SAW the angels, and that no fighting took place until the next day. I know, he was almost 90 years of age, but I had heard of this phenomenon from my uncle when I was a boy.
Anyway, probably an urban myth.
Have a great day.
