Christmas Eve, 1914. After months of intense fighting that left hundreds of thousands dead, the guns fall silent. English and German troops leave their trenches in an impromptu show of good will that would go down in history.

As the German soldiers began to sing carols, their British counterparts joined in from their trenches. Gradually, the men left their posts for No-man's-land, waving their arms to signify their peaceful intent.

La Nuit de Noël, by Gustave Doré

Little baby
I am a poor boy too
I have no gift to bring
That's fit to give our King

Shall I play for you
On my drum?
