The Marine Corps admitted Thursday that it misidentified one of the six men in the World War II photograph of a flag-raising in Iwo Jima — one of the most iconic images in American history. For more than 70 years, history said John Bradley, a Navy hospital corpsman, was one of the six men seen in the legendary photo from one of the war’s bloodiest battles. But the Marines now say Bradley is nowhere in the photo — and the man believed to be Bradley is in fact Harold Schultz, a private first class.
