QuoteDuring the first week of the push inside the Citadel at Huế, in February 1968, photographer John Olson was with Charlie Company in the thick of the fighting. Officially he was shooting for Stars and Stripes, but he carried four other cameras to take pictures he hoped to sell elsewhere.
One of the frames he shot that week was a common sight in those terrible days of urban warfare, when for a period of weeks, in seemingly permanent fog and rain, American forces and their South Vietnamese allies were locked in combat with North Vietnamese forces inside the walls of Vietnam's ancient capital. It was a photograph of a Patton tank carrying wounded U.S. Marines. The picture would become emblematic of the Battle of Huế—one of the most famous photographs from the Vietnam War and one of the great images in the annals of combat photography.
