Makeshift swamp hospital used in the Vietnam War. “A victim of American bombing, ethnic Cambodian guerrilla Danh Son Huol is carried to an improvised operating room in a mangrove swamp on the Ca Mau Peninsula. This scene was an actual medical situation, not a publicity setup. The photographer, however, considered the image unexceptional and never printed it.” Photographed by Vo Anh Khanh on Sept. 15 1970
