Iwo Jima was an unusual battle even by WWII’s tough standards. The 8-square mile island had nearly 100,000 combatants on it. In 36 days, 28,000 men died protecting or seizing this piece of volcanic rock…thousands of Japanese are still entombed there. Four out of every five men who fought on this island would either be killed or wounded. Battlefield ghosts stalk both American and Japanese survivors.  Although it was not called PTSD in 1945, it was just as destructive a condition. The men who fought on Iwo Jima describe how they coped after the war. And one fighter pilot describes the unexpected family event that brought him redemption.
