Remarks :

Introduced into the German Army late in 1914. As Gas shells it used the lacrimatory B-Stoff (with Xylyl bromide), and the lethal C-Stoff (with Mono or Tri-chloromethyl cloroformate) and D-Stoff (with Phosgene). Projectiles included a special message shell designed to burst in the air over the addresses position when all other means of delivering it had failed. A light MW shell had about the same effect as the shell of a 77mm field gun.
