Victor Lefebure, The Riddle of the Rhine: Chemical Strategy in Peace and War
“ The factories of the organic chemical industries are more silently converted into arsenals than any other type. It is true that, under normal conditions of warfare, the decisive success of a chemical campaign might be restricted by the use of other weapons, such as artillery. But, under conditions where the latter are seriously limited, the chemical weapon becomes, relatively, of much greater importance. One of the main trends in chemical warfare was the development of devices which would give long-range chemical effects without a complicated form of projector, or with none at all. ”
