ced agent projectiles for their 75 mm rapid firing gun. The British Livens Projector was a large-scale mortar developed for delivering large amounts of chemical warfare agent. Back to Top *ww1.html* The Toll of Chemical Warfare, 1914-1918It is difficult to find a definitive figure for the numbers of men injured and killed by chemical warfare agents during World War I. British casualties alone can be estimated at 185,000 injured and 8,700 dead.*ww1.html* Prentiss gives a figure of 1,296,853 casualties produced by approximately 125,000 tons of chemical warfare agents used by the combatants,*ww1.html* but it is known that in many cases the official figures underestimate the number of casualties. Furthermore, it is unclear to what degree the official figures include individuals who were injured in gas attacks but who developed serious symptoms only after the war. Given Prentiss' estimate of 10,000,000 battle deaths from the war, it is arguable as to whether chemical warfare was more or less horrific than the other methods of conducting the war.Back to Top *ww1.html* ReferencesThe historical information on this page comes primarily from the references listed below.Paxman, J.; Harris, R., A Higher Form of Killing : The Secret Story of Chemical and Biological Warfare, Hill and Wang, New York:1982, pp. 24, 32.
