Description[]
"In their journals, soldiers often recount their losing war against lice and rats in the trenches. Apart from lice powder, the only other prevention against lice was this fine toothed metal comb. Often when soldiers took leave
behind the lines, they were scrubbed down with hot water, their clothing boiled or a new uniform issued."
