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?
