French Soldiers Awaiting a German Assault?

French soldiers in trenches near Compiègne said to be awaiting a German attack but probably taken during training. The lack of any ground torn up by shell holes and the exposed position of the cameraman are good indications that this was taken during training. The closest that stereoscopic cameras seemed to have really come to photographing combat in World War I was capturing artillery shells exploding. Animated stereoview.
