The case is different with gas shells. The gas shells are the most important of all methods of using gas on the Western Front, and are still in course of development. The enemy started using them soon after the first cloud attack. He began with the celebrated...

...being followed by the use of phosgene [carbonyl chloride]. In gas shells, various substances were used. The original "tear" shells contained almost pure xylyl bromide or benzyl bromide, but some of the shells were rendered almost inactive by the presence of 20% of the dibromide. Later,... | |
