“Exactly one century ago Wednesday, German troops opened the taps on a line of chlorine tanks to send a poisonous cloud drifting across no man’s land and into World War I Allied trenches. The gas blinded soldiers and made them retch, vomit and choke, combining with bodily fluids to destroy their lungs. Today chemical warfare has come full circle. Reports from Syria about chemical weapons used in that conflict also involve chlorine — a widely available substance that has legitimate industrial and commercial uses. Both government forces and insurgents deny accusations of using the gas.”
