One of the most famous and powerful images of the Second World War: Joe Rosenthal's dramatic photo of the Marines raising the American flag atop Mount Suribachi during the horrendously bloody Battle of Iwo Jima on February 23, 1945. (Actually only five of the six are Marines; one is a Navy corpsman.) Three of the men pictured here were killed in action before the terrible battle finally ended more than a month later.
