Inside History on Instagram: "111 years ago in 1914, British and German soldiers emerged from their trenches to greet one another, exchange small gifts, wish each other a Merry Christmas, and even take part in a friendly football match. Over the next two days, the armies swapped prisoners, buried their fallen, sang carols, and played games together. When Christmas ended, the fighting resumed.
