Iwo Jima was arguable the toughest battle the marines had ever faced. The raising of the flag is one of the most iconic photographs of World War II. The courage and sacrifice of the men who fought to secure the eight miles of stinking sulphur rock and volcanic ash will never be forgotten. The inspirational story of Clint Eastwood's 'Flags of Our Fathers' and 'Letters from Iwo Jima' is captured in this new documentary that combines veteran interviews with harrowing colour footage shot by Marine Corps cameramen. One third of all Marines that died in WWII would fall at Iwo Jima. This documentary tells the untold story of the battle for Iwo Jima through the eyes of those who fought it.
