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 Two'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 Honour. Bradley, who died in 1994, never mentioned his feat to his family.
