I may have posted this heart-warming Christmas story before, but I could not find it on a search. So, here it is from an AP post:
With British and German forces separated only by a no-man’s land littered with fallen comrades, sounds of a German Christmas carol suddenly drifted across the frigid air: “Stille Nacht, Heilige Nacht” (“Silent Night, Holy Night”).
Then, during that first Christmas Day in World War I, something magical happened. Full report is here.
