The Illustrated "All Quiet on the Western Front"
"In the meantime it has become pitch dark. We skirt a small wood and then have the front line immediately before us.
An uncertain, red glow spreads along the sky line from one end to the other. It is in perpetual movement, punctuated with the bursts of flame from the muzzles of the batteries. Balls of light rise up high above it, silver and red spheres which explode and rain down in showers of red, white and green stars. French rockets go up, which unforld a silk parachute to the air and drift slowly down. They light up everything as bright as day, their light shines on us and we see our shadows sharply outlines on the ground. They hover for the space of a minute before they burn out. Immediately fresh ones shoot up to the sky, and again green, red and blue stars.”
