Knowing that their gas masks could protect them only for two hours or less, the defenders fled for their lives, though 500-600 still died. At 02:00, 894 metal tubes (Gaswurfminen) dug into a reverse slope were triggered electrically to simultaneously fire canisters containing 600 ml of chlorine and phosgene gases, smothering the Italian trenches in the valley in a dense cloud of poison.
