The Battle of Iwo Jima, fought in the winter of 1945 on a rocky island south of Japan, brought a ferocious slice of hell to earth: in a month's time, more than 22,000 Japanese soldiers would die defending a patch of ground a third the size of Manhattan, while nearly 26,000 Americans fell taking it from them. The battle was a turning point in the war in the Pacific, and it produced one of World War II's enduring images: a photograph of six soldiers raising an American flag on the flank of Mount Suribachi, the island's commanding high point.

One of those young Americans was John Bradley, a Navy corpsman who a few days before had braved enemy mortar and machine-gun fire to administer first aid to a wounded Marine and then drag him to safety. For this act of heroism Bradley would receive the Navy Cross, an award second only to the Medal of Honor.
