Here are a couple more pictures from the Mid-Week Pictorial. The first is captioned "British troops constructing trenches in a flooded area near Blangy in France" and is from Vol. VII no.2 (March 14,1918). The second photo is "A British wiring party under the leadership of an officer setting out on the perilous duty of repairing wire defenses" and is from Vol. VI no. 26 (February 28, 1918).
