"In June, 1918," the memorandum asserts, "the following shipment of gases in bulk was made to the American forces in France to be exchanged for gas shell: Mustard gas, 15 tons; chlorin, 705 tons; phosgene, 48 tons. Further shipment in bulk over seas was stopped pursuant to a cablegram from France dated July 21, 1918, the reason for this being that France had no more extra gas shells to be filled with American gas.
"There not being gas shell available with suitable boosters and adapters, the gas plants were not operated to capacity. However, sales of some excess gas were made both in England and to France. England was sold 900 tons of chlorin and 368 tons of phosgene. France was sold 300 tons of chlorin and 1,408 tons of chlorin, equivalent to 1,126 tons of phosgene. Phosgene is 50 percent chlorin, and France furnished phosgene shell in exchange for this chlorine. In addition to the above 200 tons of mustard gas were shipped to England for loading shell originally made for Russia. These shells were never loaded, and the gas, at least a large part of it, was utilized by the English in loading shell."
