Christmas Truce, Flanders, December 24, 1914.
Germans were warned that if they staged another truce, they would be shot. British soldiers were threatened with court martial. But many of the men who took part in the Christmas truce refused to fire on their opponents again until the day they were rotated out and other soldiers came to take their place. Many memorials in Britain remind us of it and it was widely publicised in the British press. In Germany it wasn't and there is no memorial.
"On the whole, people don’t generally like to kill one another."
