History.com has a somewhat sentimental summary of the even Christmas Truce of 1914 (undated).
Here's a story from today - literally - about the “1914-2016, Great Britain vs. Germany Christmas Football” event (E.B. Boyd, German, British soldiers commemorate WWI Christmas Truce on Kabul soccer field Stars and Stripes 12/25/2016):
On that first Christmas of World War I, German and British soldiers laid down their weapons, climbed out of their trenches, and celebrated the holiday together in the no-man’s land that lay between them. According to some accounts, impromptu games of soccer broke out.No word on whether on whether any Taliban fighters took part.
In Sunday’s match, soldiers took to the pitch — a soccer field long ago transformed into a helicopter landing zone — for two 20-minute halves. The sidelines were a confetti of uniforms as soldiers from NATO partner countries, including Australia, Italy, Romania, Belgium, and Czech Republic, together with officers from the Afghan army. A handful of Afghans from a school next door spilled through a gate and watched from the far side of the field.
