Here is a magazine article which sought to explain to American readers the workings of one of the cruelest of the World War I inventions:
"Among the many scientific tools of destruction employed in the war, the so-called "flammenwerfer" of the Germans, a more or less hose-like apparatus for hurling jets of flaming liquid, holds an important place..This idea of projecting upon the adverse trenches and their occupants a rain of liquid fire was no sudden afterthought of the German mind. It was conceived, studied, and perfected for several years before the war, and its history may be traced in the German patent office."
