WWI Christmas truce drawing from the London News of January 9, 1915. The drawing’s caption reads, in part, “British and German soldiers arm-in-arm and exchanging headgear: a Christmas truce between opposing trenches. Drawn by A. C. Michael.”

On December 24, 1914, German and British soldiers laid down their arms and crossed into the “No Man’s Land” separating their trenches. They sang Christmas carols, played games, and shared jokes and beer. They also used the time to bury their dead.

Hundreds and perhaps thousands of men on the Western Front experienced the informal truce. The war had begun only months earlier.
