Smoke generators German

To resolve this problem chemical officers, with the approval of Maj. Gen. Lucian K. Truscott, Jr., the corps commander, came up with a new technique for the mechanical smoke generator—the production of a light haze in the area between the harbor and the front lines, thin enough to permit normal operations within it, thick enough to prevent German observation from the encircling hills. ... 

According to plan, the companies of the 23d Smoke Generator Battalion were to have assumed the smoke mission at Omaha on D plus 3.

Both companies experienced a great deal of difficulty. Men and equipment became separated some roads indicated on the map were nonexistent and others were heavily mined or subject to enemy fire.

One of the earliest and by far the most efficient material used in the war for generating artificial smoke was phosphorus. This element exists in two allotropic forms white phasphorus and red phosphorus. WTiite phosphorus, tlie normal and common form, was discovered in 1669 by the German chemist, Brand, who noted that it is spontaneously inflammable at ordinary temperatures and bums with a dense white smoke. While both white and red phosphoru.s were used in the war, white phosphorus was by far the most effective and the most widely ofnployed and is the form now generally denoted by the word pho phoru9.
