In this Feb 23, 1945 file photo, U.S. Marines of the 28th Regiment, 5th Division, raise the American flag atop Mt. Suribachi, Iwo Jima, Japan. James Bradley, who wrote the book “Flags of Our Fathers,” said in a telephone interview Tuesday, May 3, 2016, that questions raised about the photo by two amateur historians, which have prompted a Marine Corps investigation, led him to think back on comments his father made about the 1945 flag-raising. Those comments by John Bradley, who died in 1994, now lead James Bradley to believe his father participated in an earlier flag-raising, but not the one captured in the famous picture.
