1920 Rotogravure WWI Phosphorous Bomb Explosion Combat Illuminate Enemy WAR1

This is an original 1920 World War I sepia rotogravure of a phosphorous bomb explosion in Gondrecourt, France. These bombs were used to illuminate enemy positions at night, marking them for attack or artillery fire. The phosphorous burns so hot and bright that it can set most anything on fire, especially combustibles like ammunition. This incendiary ammunition also creates a smoke screen, preventing the enemy from strategically fleeing, while maintaining coverage for allied forces to change positions.
