"I saw some rats running from under the dead men's greatcoats, enormous rats, fat with human flesh. My heart pounded as we edged towards one of the bodies. His helmet had rolled off. The man displayed a grimacing face, stripped of flesh; the skull bare, the eyes devoured and from the yawning mouth leapt a rat." Many men killed in the trenches were buried almost where they fell. These corpses, as well as food scraps that littered trenches, attracted rats. Quotes from soldiers fighting in the trenches: 'Gassed'. Painting by John Singer Sargent, 1918/1919.
