‘The Best Photo From Vietnam’: One Photographer’s Defining Image of War

Like the soldiers he was photographing, Art Greenspon was in his 20s when he traveled to Vietnam to document the war. After five months in-country, Greenspon went on a two-day patrol with soldiers in the A Shau valley, just inside the Laotian border. There, after an ambush and subsequent firefight, Greenspon made a photograph that David Douglas Duncan, the famous TIME-LIFE war photographer, lauded as the “best picture yet of the Vietnam War.”
