Liquid Fire Attack [ASE label]
Billowing clouds of smoke over no-mans land after an attack utilizing a flame-thrower (or Flammerwarfer in German). The weapon was developed in Germany in 1900, and thought it was determined to be useful agains enemy defenses, trenches, and tanks, the flame-thrower never went into wide-scale production and deployment. One notable instance was at Hooge during the Second Battle of Ypres, July 1915. Despite few casualties,the Germans captured whole trenches with six flame-throwers. A general sense of demoralisation among the British troops was reported by their commanders. The second instance was wtih the knapsack sprayer model, used successfully by the Royal Navy in the Zeebrugge Raid in 1918.
