The Paris Review shares this image of a story about Ernest Hemingway, wounded on the Italian Front. The article follows the reminiscence of a soldier hospitalized next to Hemingway in the summer of 1918, and the experiences in the hospital may have crept into A Farewell to Arms.
“Hemingway was a good-looking son-of-a-gun, I thought, lying there fresh-faced and clean-shaven on the white-painted iron bedstead…he had a strong jaw and a wide boyish grin that revealed an even row of dazzling white teeth, and his jet black hair and dark eyes contrasted starkly with the snowy pillows that propped up his broad shoulders as he reclined at full length, one leg in a plaster cast, the other swathed in bandages.”
