German And French Soldiers Aka Troops On March (1914)

German and French soldiers at start of World War One. Shot looking down at the troops walking through a very narrow and shallow trench or ditch; they are crouching down while walking. MS soldier leaning against fortified wall of trench; another comes over and looks over top with binoculars. 3 soldiers struggle to mount a piece of machinery (not certain if it is part of weapon or some sort of periscope). Soldiers walk through trench carrying guns; they pass other gunners already in position. Another shot looking down at soldiers walking through primitive trench. Then they join the main trench which is a bit wider; has ladders leaning against front. Good shot of officer talking to soldiers in trench; one man stands guard; others sit. The soldiers get up and creep away back through connecting trench. Again; shot of soldiers standing guard Now the other side: French Army troops in trench; loading something to be shot from rifle - flares or smoke bombs or even poison gas? French soldiers march past. S
