"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, always fighting for breath, with voices a mere whisper, saying that their throats are closing and they know they will choke."
