'At two minutes to eleven, opposite the South African Brigade, at the eastern-most point reached by the British armies, a German machine-gunner, after firing off a belt without pause, was seen to stand up beside his weapon, take off his helmet, bow, and then slowly walk to the rear.' -John Buchan
I can't help but think that every time something is proven, a little bit of the magic of the world dies.
