John Singer Sargent's painting Gassed hangs in the Imperial War Museum in London; the canvas is over seven feet high and twenty feet long. This impressive painting depicts soldiers blinded by gas being led in lines back to the hospital tents and the dressing stations; the men lie on the ground all about the tents waiting for treatment.


"With mustard gas the effects did not become apparent for up to twelve hours. But then it began to rot the body, within and without. The skin blistered, the eyes became extremely painful and nausea and vomiting began. Worse, the gas attacked the bronchial tubes, stripping off the mucous membrane. The pain was almost beyond endurance and most cases had to be strapped to their beds. Death took up to four or five weeks. A nurse wrote:

I wish those people who write so glibly about this being a holy war and the orators who talk so much about going on no matter how long the war lasts and what it may mean, could see a case--to say nothing of ten cases--of mustard gas in its early stages--could see the poor things burnt and blistered all over with great mustard-coloured suppurating blisters, with blind eyes . . . all sticky and stuck together, and always fighting for breath, with voices a mere whisper, saying that their throats are closing and they know they will choke."
