FOG OIL being used to produce a smoke screen to limit observation during river crossings. This function of the Chemical Warfare companies was utilized in covering the activities of troops at ports, airfields, docks, and harbors in addition to concealing vital points from direct enemy air observation during advances and river crossings. When the danger of aerial attack was practically eliminated it was still used against ground observation. By means of a generator the fog oil was converted into a white fog which was used effectively whenever the wind conditions were not strong enough to disperse the screen too rapidly.
90-MM. ANTIAIRCRAFT GUN M 1 being fired at a German flying bomb passing over Belgium. Liege was subjected to an attack by these robot bombs and suffered considerable damage. Because of the great speed of these weapons it was difficult to combat them, but later with the utilization of the newly developed proximity fuse, the seriousness of the threat of the flying bombs diminished.
